I think we have too much feel good stuff here. Alon Alon, agreed! ALL drugs, indeed all nutrients, are potential poisons under certain circumstances. Even the two most essential nutrients for live - air and water - can kill if they are taken in excess. Water toxicity is well documented in calves and pigs deprived of water for a few days and then allowed access to ad- libitum water. IMO, the body must process (metabolise/handle) ALL molecular substances [including air & water] absorbed into it, whether from digesta, skin or lungs. Through its organs, detox-, circulatory- and excretory- systems, it uses what it needs, and stores or excretes what it does not need; it neutralises or complexes metabolisable toxins and excretes or stores the byproducts. IMO, the same principle applies to herbs. Herbs have many active compounds [alkaloids, glycosides, oxalates, etc] that can be toxic under certain circumstances. Toxic compounds in herbs can (and do) cause toxicity or adverse reactions. For example, plant poisoning is well known in cattle [rhododendron, senecio, veratrum, claviceps, digitalis, pterydium, taxus, nitrate poisoning, etc]. In USA, selenium toxicity in range-cattle occurs when they eat excessive amounts of Se-accumulator plants, such as astragalus. If these plants grow in an area with toxic Se levels in the soil, they can accumulate up to 10,000 ppm Se in their dry matter! Whether or ot toxicity occurs after ingestion of herbal materials depends mainly on (a) the levels of toxic substances in the plant; (b) the dose and dose-intervals of the plant, and © the health status of the subject. Subjects whose Detox Systems are fully operational, and who have not been loaded previously with stored toxin [like heavy metal, etc] can cope easily with toxin doses that could kill subjects with a compromised Detox System. For example, the media hype over deaths in people taking products containing Kava or Hypericum was ludicrous. One MUST expect that ANY potent drug [herbal or otherwise] poses high risk in subjects whose livers or kidneys are damaged [bEFORE herbal use] by severe cirrhosis, hepatitis or nephritis. The subsequent sales ban on Hypericum and KAVA products was a cynical and self-interested attack on herbal medicine by its opponents. The western drug Industry pumps milliions (billions?) of dollars into research each year. The industry has the universities and research institutes on their side, if only because those institutions DEPEND on industry for funding. An organisation that " does not play ball " with the industry will receive no funding from that industry.

Agreed. In contrast to Pharma research, herbal research funding is relatively pathetic. Thus, there is a relative (some would say appaling) LACK of good research in many aspects of the safety, efficacy and mechanisms of action herbal medicines. There is also relatively little good research on the interactions between herbs, interactions between their active ingredients, and interactions with western drugs. Whether we like it or not, many people [even many of our friends!) see us [herbalists or holistic practitioners] as oddballs, practicing a scientifically unproven and under-researched if not highly dubious medicine. In contrast to public perception, the INDUSTRY and its minions take us VERY seriously! They see us as the SINGLE greatest challenge to their enormous profits and will do all that they can to bury us. That could include funding moles within our ranks, and funding herbal research projects that they expect will produce poor results or show adverse effects.

Quackbusters will attack on all fronts. But the question of the wisdom of using steroidogenic herbs in steroid-sensitive cancer is a prime target for Quackbusters. In warefare, one is advised to know the enemy and attack the weakest defences. Mammary and prostate cancer are day-to-day concerns of the public. Everyone knows someone afflicted with those conditions, and many fear that they may develop them themselves. THAT is why I see the oestrogen- or androgen- sensitive cancers as being to important. They are a potential battle-ground for the industry to highlight the confusion and scarcity of REAL research knowledge in our ranks. Many western drugs and herbal molecules work by activating or blocking cell-receptors. IMO, we should AVOID known oestrogenic/androgenic herbs/formulas in mammary and prostate steroid-sensitive cancers unless we are fairly sure that they are SAFE [i did not say EFFECTIVE!]. Comments?

Guest guest Posted October 2, 2003 Report Share Posted October 2, 2003 hi all, one of the things we bneed to realise is that all things are poisonous to our body depending on dosage. one mans food is another mans poison. same with medicines. theya re more potent. CM drugs are natural, so their absorption & strength is limited. being natural they can be detoxed easily. synthetic drugs are harmful as detox is harder. its same as opium & heroin, besides this the dosage can have a harmful effect too. we have to be careful that today drug companies are now producing natural health food supplements, vutamins, minerals & other products synthetically. this may have the same level of damage to the body organs as synthetic drugs(medicines). so look out. anand --- < wrote: > HI All, > > Emmanuel wrote: > > Alon, Most of the reference books on > pharmaceuticals describe > > specific pathways of metabolism and excretion. > They're pretty > > much mostly metabolized as poisons by the liver > and kidney.

Guest guest Posted October 3, 2003 Report Share Posted October 3, 2003 Well put piece. If you look at the case of PC-SPES you will see how this formula was first heralded by urologists and oncologists as a worthy drug in the armamentarium against prostate cancer (and indeed some other cancers as well - check PubMed). HOWEVER, when it was discovered the formula was not as squeaky clean as the makers claimed all hell let loose. Not one WM doc stood up to put in a word for PC-SPES. It was withdrawn from the market after heavy pressure from the FDA and California HD. Men using PC-SPES to suppress advanced PC either died, had to go back on conventional meds such a Zoladex, Lupron, Casodex or Flutamide (horrible side effects) or took their chance with herbal analogs such as PC-PLUS. > Many western drugs and herbal molecules work by activating or blocking cell-receptors. IMO, we should AVOID known oestrogenic/androgenic herbs/formulas in mammary and prostate steroid-sensitive cancers unless we are fairly sure that they are SAFE [i did not say EFFECTIVE!]. Despite the clamour against PC-SPES there is no clear evidence that it promoted androgen independent PC any more than conventional medicines. What is more PC-SPES had a cancer cell kill effect in its own right. For example, reports in peer reviewed journals were coming out that PC-SPES was effective in treating colon cancer (again check PubMed if you feel the need to follow this up). That is something the conventional meds have never had. Safety is another issue, I agree. Problems of formula consistency and herb quality abound. Together of course with a general lack of understanding of the true mechanism(s) of action. But you are right Phil, there was an enormous effort to get PC-SPES off the market so that it was not a thrreat to conventional meds. After all, you can't have 100,000's of PC patients self medicating at 1/4 the Big Pharma price can you ! There now comes another strange 'herbal' by the name of DIM which is the extract of cabbage. Diindolylemethane (DIM) is the digestive product of enzymatically reduced brassicans first converted to indoles by mastication, primarily I3C (indole-3-carbinole) and then DIM in the gut. 200 mg + doses of DIM have been shown to act as steroid receptor disruptors for both BC and PC. In others words, DIM is something like Tamoxifen and Casodex put together in one. At lower doses DIM blocks CYP450 enzymatic production of 16-alpha-hydroxyestrone (16a-OH1) a highly carcinogenic estrogen implicated in BC and probably PC as well. DIM has a 'subtle effect' : Its electronic cloud configuration is similar to the anti-androgen (AA) Casodex. Casodex (like Tamoxifen which is effectively an anti estrogen AE) has a 'lock and key' action with steroid receptors. Once the AA/AE key docks into the steroid receptor(s) found on most cells, there is no way for the real steroid to reach the cell and activate cellular processes like growth and mitosis. This blocking effect has been used for years to suppress sex-steroid cancers. Now a cheap vegetable extract has been found to do the same thing as highly expensive drugs. Time will tell how the FDA and Big Pharma deal with this threat, but here is a clue that DIM, like PC-SPES may have a naturally limited 'life-cycle' if that is the right word to use: Eventually cells learn to treat Casodex and Tamoxifen as if they were androgens and the cellular processes go on again in a new form, often in the guise of far more aggressive cancer. This may be because conventional AA's and AE's have a similar chemistry to sex-steroids and are able to initiate intracellular cAMP cascade instead of the real steroid. Now, PC-SPES (and analogs) and DIM are chemically different to steroids. They are similar in the morphological configuration only - hence they may be *incapable* of initiating the ugly cellular adaptations found with conventional AA's and AE's. Time will tell. Hope that helps. But you are right Phil, stay away from steroid receptor disruptors if you want TCM to stay clean dealing with BC and PC. There are other things out there that address the cancer process in a TCM way. Sarcandra for example has been used to relieve stasis in the pelvis. It is most unfortunate that the product available in the west Xin Huang Pian is contaminated with the western anti-inflammatory Indometacin. Indometacin has a side effect profile that beggars belief and why commercial preparations should include it baffle me. Yun Zhi has also been used to address immune system imbalance which also may play a part in cancer process. Work by John Tindall at the Yuan Clinic may be of interest here, if anyone knows John ..

Guest guest Posted October 3, 2003 Report Share Posted October 3, 2003 Hi Phil, I accept your crossposting as acceptable since you are quoting and addressing people on both lists. Seems ethical to me, but my apologies to those who feel bruised by this. Phil, I can't think of anything to say except nutrients in normal amounts do not cause hepatomegaly (liver enlargement and injury), while drugs in normal amounts often do cause hepatomegaly or at least some extra work by the liver. Now I'll jump completely over to your side, Phil, and point out that simple food intake and metabolism is presented by physiologists as the most stressful thing we do over a lifetime. Makes you want to subsist on moderate doses of well cooked and pureed soup doesn't it? This is exactly what I do when I compete as a distance runner. Low stress foods and plenty of sleep makes me a more energetic athlete. That's all I can think of for the moment aside from a recommendation that you look at the molecules characterized in an August, 1998 research article in the Journal of Chromatography A. Dr. Lin, et. al. characterized 26 new ring structured molecules in Dang Gui, Angelica sinensis Radix. None of them are steroids, but some have 5 or 6 rings that show resonance. Makes my biochemist heart smile. I have similar articles that look at newly found molecules in Huang Qi, Wu Wei Zi and a number of other herbs. Probably pretty boring for most of the list, but I figured you, Phil, would get off on it. If you have a fax number in Ireland, I'll fax you the two pages that shows the 26 cool ring structured molecules found in Dang Gui. There's one ligustilide dimer that has a fifth hidden resonant ring ... I love it. Hey, it's no worse than collecting stamps, coins or Barbie dolls.

I think we have too much feel good stuff here. Alon Alon, agreed! ALL drugs, indeed all nutrients, are potential poisons under certain circumstances. Even the two most essential nutrients for live - air and water - can kill if they are taken in excess. Water toxicity is well documented in calves and pigs deprived of water for a few days and then allowed access to ad- libitum water. IMO, the body must process (metabolise/handle) ALL molecular substances [including air & water] absorbed into it, whether from digesta, skin or lungs. Through its organs, detox-, circulatory- and excretory- systems, it uses what it needs, and stores or excretes what it does not need; it neutralises or complexes metabolisable toxins and excretes or stores the byproducts. IMO, the same principle applies to herbs. Herbs have many active compounds [alkaloids, glycosides, oxalates, etc] that can be toxic under certain circumstances. Toxic compounds in herbs can (and do) cause toxicity or adverse reactions. For example, plant poisoning is well known in cattle [rhododendron, senecio, veratrum, claviceps, digitalis, pterydium, taxus, nitrate poisoning, etc]. In USA, selenium toxicity in range-cattle occurs when they eat excessive amounts of Se-accumulator plants, such as astragalus. If these plants grow in an area with toxic Se levels in the soil, they can accumulate up to 10,000 ppm Se in their dry matter! Whether or ot toxicity occurs after ingestion of herbal materials depends mainly on (a) the levels of toxic substances in the plant; (b) the dose and dose-intervals of the plant, and © the health status of the subject. Subjects whose Detox Systems are fully operational, and who have not been loaded previously with stored toxin [like heavy metal, etc] can cope easily with toxin doses that could kill subjects with a compromised Detox System. For example, the media hype over deaths in people taking products containing Kava or Hypericum was ludicrous. One MUST expect that ANY potent drug [herbal or otherwise] poses high risk in subjects whose livers or kidneys are damaged [bEFORE herbal use] by severe cirrhosis, hepatitis or nephritis. The subsequent sales ban on Hypericum and KAVA products was a cynical and self-interested attack on herbal medicine by its opponents. The western drug Industry pumps milliions (billions?) of dollars into research each year. The industry has the universities and research institutes on their side, if only because those institutions DEPEND on industry for funding. An organisation that " does not play ball " with the industry will receive no funding from that industry. Ze'v wrote: > There are presently no mechanisms to study herb interactions in > prescriptions, although we can safely say that there are more > complex interactions and more complex pharmacodyamics in the body > that with most medications. Agreed. In contrast to Pharma research, herbal research funding is relatively pathetic. Thus, there is a relative (some would say appaling) LACK of good research in many aspects of the safety, efficacy and mechanisms of action herbal medicines. There is also relatively little good research on the interactions between herbs, interactions between their active ingredients, and interactions with western drugs. Whether we like it or not, many people [even many of our friends!) see us [herbalists or holistic practitioners] as oddballs, practicing a scientifically unproven and under-researched if not highly dubious medicine. In contrast to public perception, the INDUSTRY and its minions take us VERY seriously! They see us as the SINGLE greatest challenge to their enormous profits and will do all that they can to bury us. That could include funding moles within our ranks, and funding herbal research projects that they expect will produce poor results or show adverse effects.

Quackbusters will attack on all fronts. But the question of the wisdom of using steroidogenic herbs in steroid-sensitive cancer is a prime target for Quackbusters. In warefare, one is advised to know the enemy and attack the weakest defences. Mammary and prostate cancer are day-to-day concerns of the public. Everyone knows someone afflicted with those conditions, and many fear that they may develop them themselves. THAT is why I see the oestrogen- or androgen- sensitive cancers as being to important. They are a potential battle-ground for the industry to highlight the confusion and scarcity of REAL research knowledge in our ranks. Many western drugs and herbal molecules work by activating or blocking cell-receptors. IMO, we should AVOID known oestrogenic/androgenic herbs/formulas in mammary and prostate steroid-sensitive cancers unless we are fairly sure that they are SAFE [i did not say EFFECTIVE!]. Comments?

Agreed, in most cases. I accept your point about WM drugs and liver. However, we see conditions in animals where energy-dense feed [for example high-concentrate diets in cattle, or high-energy forced- feeding of Strasbourg geese] causes massive fat-infiltration into liver; liver fat content can rise to 20-40%, with swelling of the liver and great increase in serum liver enzymes. Such livers are under severe metabolic stress, with clinical consequences that include lowered immunity, laminitis/hoof- lameness [equivalent to " nail-bed " disorders in humans], infertility, indigestion and rumen acidosis [LV overacting on ST in cattle, not geese!], etc. It is uncanny how well some of the LV Syndromes in TCM reflect in clinical findings in western vet practice! A rare manifestation of grain-acidosis in cattle is hypocalcaemia, with spasms, tetany, or paresis. LV-Fire/Wind Rising? Another COMMON situation with " NORMAL " feed occurs when cattle are on heavily fertilised grass. Mean N values in Irish grass are 3.5% DM, equivalent to crude protein values of 23%. On heavily fertilised grass, N values can reach 5-6% DM, equivalent to 31-37% crude protein in the DM. The enormous amount of N absorbed [mainly as ammonia and amino acids] must be converted into urea and proteins in LV. These livers cannot cope and serum urea-N values [bUN] rise markedly. > Now I'll jump completely over to your side, Phil, and point out > that simple food intake and metabolism is presented by > physiologists as the most stressful thing we do over a lifetime. > Makes you want to subsist on moderate doses of well cooked and > pureed soup doesn't it?

I don't make that premise. Herbs are thousands of things: nutrients, medicines, and things that I have yet to imagine. And that's just in reference to the molecules. What is toxic to one person, may be nutritional balance to another. Emmanuel Segmen Quote Link to comment Share on other sites More sharing options...
Guest guest Posted October 5, 2003 Report Share Posted October 5, 2003 Hi Jackie, Because society usually views them as special animals, there is little research on horses relative to cattle. For example, a search of CAB Abstracts for the profile (fatty or steato* or fat-infiltration) and (liver or hepat*) and (horse? or mare? or equine) gave only 67 hits, as compared with 908 hits for the same profile for cattle. Very few of the equine hits were relevant. There are virtually no fat stores in the liver of newborn foals (Stammer et al, 1991). Postnatal fat accumulation in equine liver is associated with dietary and pathological factors. Ocana-Quero et al (1993) and Carroll et al (1987) suggest that enterotoxaemia associated with excessive carbohydrate intake caused liver damage, including fatty degeneration/fatty liver, in horses. A genetic component is involved; the Morgan breed appears more predisposed metabolically than Thoroughbreds to laminitis and associated fatty liver (Janson, 1980). Hepatic fatty degeneration in horses can occur in Tyzzer's disease, toxicosis (aflatoxin, fumonisin) from fungal-contaminated feed and other hetatoxoxins, such as camphechlor (toxaphene) poisoning. Hepatic lipidosis [fatty infiltration] can be a non-specific concomitant of hepatocyte necrosis in many liver pathologies, including some bacterial infections and equine herpes virus 1 infection and equine dysautonomia (grass sickness). Stress and undernutrition/starvation can mobilise fat from storage depots, causing hyperlipaemia and increased fatty acid levels in blood. This can cause fatty liver also. Acland-HM; Mann-PC; Robertson-JL; Divers-TJ; Lichtensteiger-CA; Whitlock-RH | Toxic hepatopathy in neonatal foals. | Veterinary- Pathology. 1984, 21: 1, 3-9; 23 ref. LA: English | Six foals and three different breeds, born to healthy mares, and normal at birth, died at 2-5 days of age with icterus, ataxia, head pressing, and terminal hepatic coma. Their livers were less than one-half normal weight. Most of the liver was dark red-brown and slightly rubbery. Histologically, these areas were characterized by severe bile ductule proliferation, mild portal tract fibrosis, and massive hepatocellular necrosis and lobular collapse. A small proportion of the liver, usually on the peripheral part of the lobes, was grossly light brown and slightly raised. Histologically, these areas had mild to severe bile stasis in canaliculi. In the thin marginal zone between the severely affected and mildly affected liver, there was mild bile ductule proliferation and periportal fatty change and necrosis. Alzheimer's type II cells, characteristic of hepatoencephalopathy, were numerous in the brains of all foals. Within two hours after birth, all the foals had been given an oral proprietary nutritional paste (PrimaPaste SL), the ingredients of which included a viable Aspergillus sp. and an iron compound. Similar lesions were produced in an experimental foal given three tubes of the paste. The lack of significant inflammation in the liver suggested a deficiency or toxic cause to be more likely than an infectious or immune mediated one. PT: Journal-article AN: 842240041 Bauer-JE; Ransone-WD | Fatty acid composition of serum lipids in fasting ponies. | Lipids. 1983, 18: 6, 397-401; 15 ref. LA: English | Hyperlipidaemia in horses presented for treatment of various diseases associated with food deprivation has been described [see VB 39, Abst 3496]. Alterations in the fatty acid distribution of total lipid extracts and of 4 of the major lipid subclasses of serum in ponies starved overnight and for 4 and 7 days were determined. Although there were changes in individual fatty acids, overall there was no significant change in the ratio of saturated to unsaturated fatty acids in the total extracts. Phospholipids became enriched in saturated fatty acids owing to a decrease in 18:1, but this response was variable. The free fatty acid and triglyceride fractions both showed increases in relative amounts of 18:3omega3 and a decrease in 18:0 and a concomitant change in the saturated: unsaturated fatty acid ration. This was attributed to mobilization of an increased proportion of polyunsaturated fatty acids from tissue sites with their subsequent incorporation into triglyceride by the liver.

LA: English | During a period of drought 17 lactating mares were fed a daily diet of 7-8 kg wheaten hay and 4-5 kg concentrates containing 5.8% crude fibre. During subsequent rainfall the concentrate was withdrawn and oat hay, which was unpalatable, then whole oats and a little hay were fed for three days, followed by a new supply of concentrate and oat hay, one day after which two animals were found dead. Subsequently one was killed in extremis; 6 became ill and one further died at 6 days. For four days only wheat hay was fed, then oats were introduced to unaffected lactating mares and one died the next day. Symptoms included enteritis, abdominal pain, lameness, acute laminitis, pyrexia, cyanosis, limb oedema and tachycardia. PM lesions included gastric distension, intestinal hyperaemia, pulmonary congestion, fatty liver, nephrosis, epicardial petechiation and, in one case, rotation of the os pedis of both fore feet. Cultures of faeces from 8 mares yielded large numbers of coliforms and enterococci. Cultures of the small and large intestinal contents of the last mare to die yielded large numbers of Clostridium perfringens type D which was producing 80 mouse lethal units of toxin per ml of small intestinal contents. No further cases followed removal to pasture on another farm.

LA: English | The metabolic effects of feeding soyabean oil instead of an isoenergetic amount of maize starch plus glucose were studied in ponies. Twelve adult Shetland ponies were given a control diet (15 g fat/kg DM) or a high-fat diet (118 g fat/kg DM) according to a parallel design. The diets were fed for 45 d. Plasma triacylglycerol (TAG) concentrations decreased by 55% following fat supplementation. Fat feeding also reduced glycogen concentrations significantly by up to 65% in masseter, gluteus and semitendinosus muscles (P < 0.05, P < 0.01 and P < 0.01 respectively). The high-fat diet significantly increased the TAG content of semitendinosus muscle by 80% (P < 0.05). Hepatic acetyl-CoA carboxylase and fatty acid synthase activities were 53% (P < 0.01) and 56% (P < 0.01) lower respectively in the high- fat group, but diacylglycerol acyltransferase activity was unaffected. Although carnitine palmitoyltransferase-I (CPT-I) activity in liver mitochondria was not influenced, fat supplementation did render CPT-I less sensitive to inhibition by malonyl-CoA. There was no significant effect of diet on the activity of phosphofructokinase in the different muscles. The activity of citrate synthase was raised significantly (by 25%; P < 0.05) in the masseter muscle of fat-fed ponies, as was CPT-I activity (by 46%; P < 0.01). We conclude that fat feeding enhances both the transport of fatty acids through the mitochondrial inner membrane and the oxidative capacity of highly-aerobic muscles. The higher oxidative ability together with the depressed rate of de novo fatty acid synthesis in liver may contribute to the dietary fat-induced decrease in plasma TAG concentrations in equines.

LA: English | The administration of carbon disulphide to horses and calves in which the hepatic microsomal amido-pyrine N-demethylase activity had been raised by daily dosing with phenobarbital for 14 days, was followed by a rapid fall in the induced microsomal enzyme activity and the development, in calves, of bilirubinaemia and clinical jaundice. These changes were accompanied by the release of live specific enzymes into the plasma and centrilobular liver cell necrosis with ballooning of the central and midzonal cells, fatty changes, loss of glycogen and of intracellular enzyme activity. The same dose of disulphide given to horses and calves which had not been pretreated with phenobarbital did not cause jaundice and no liver changes were detected. It is suggested that the product of the metabolism of disulphide by the microsomal enzymes of horses and cattle is hepatotoxic.

LA: English LS: German, French | Spontaneous Tyzzer's disease is described in two quarter horse foals which died suddenly with no clinical history of apparent illness. Significant gross findings included icterus, focal pale tan areas in the liver and catarrhal enterocolitis. Focal dark red lesions were present in the small intestine of one foal, and the mesenteric lymph nodes of another were enlarged and hyperaemic. Histologically, the liver showed multiple discrete and confluent foci of necrosis, fatty change, sinusoid congestion and haemorrhage. Bundles of intracytoplasmic bacilli were demonstrated in hepatocytes at the margin of liver lesions using special stains. Infiltration of the portal triads with inflammatory cells and biliary duct hyperplasia and degeneration were also observed. Lesions in the intestine were characterised by mucosal necrosis with inflammatory cell infiltration, increased mucus production, submucosal lymphois hyperplasia and, in one foal, submucosal haemorrhage. Necrosis of lymph follicles, congestion and haemorrhage were also present in the spleen and mesenteric lymph nodes.

LA: English | Breed susceptibility to laminitis was assessed through a nationwide poll of 235 equine veterinary practitioners. Laminitis occurred in 0.92% of the horse population, with the American Quarter Horse (AQH) being the most susceptible breed. In practices limited to either AQH or Thoroughbreds (the 2 most common breeds in the USA), the AQH had an incidence of laminitis 8 times greater than the Thoroughbred. However, the recovery rate of the AQH was 1.3 times higher; Thoroughbreds had a 5-fold higher death rate than AQHs, primarily due to complications of the disease. During Sep.- May, concentrations of serum phospholipids, triglycerides, total cholesterol, NEFAs and glucose were recorded in 15 fasting horses (8 Morgans and 7 Thoroughbreds). Morgans had higher concentrations of total lipid than Thoroughbreds, although the relative proportions of each type of lipid were similar. Morgans showed less ability to clear and metabolise glucose in response to glucose, insulin and adrenaline administration, and the amount of insulin secreted was less than in the Thoroughbred, which was more prone to hypoglycaemic shock. Increased mobilisation and clearance of NEFAs during adrenaline administration and insulin tolerance tests were seen in Morgans but not in Thoroughbreds. Tests showed Morgans to tend towards hypothyroidism, and to have some degree of hepatic impairment. It was concluded that the Morgan appears more predisposed metabolically than the Thoroughbred to laminitis and associated fatty liver.

LA: Portuguese | The first focus occurred in 1985 in Salvador Bahia, causing the death of 11 donkeys. Histopathological examination revealed a non- suppurative interstitial nephritis with large numbers of parasites in the tubules. The liver showed severe fatty degeneration probably caused by treatment administered. The second focus was seen in 1988 in a Thoroughbred horse originating from Bananal and being kept at the Jockey Club, Sao Paulo. The animal was killed because of a broken humerus. At PM examination, formaldehyde- fixed kidney sections stained by haematoxylin and eosin showed interstitial nephritis and many parasites at different stages of development (uninuclear, microgametes, macrogametes, sporoblasts, sporocysts) were seen in the nephrons. This seems to be the first identified record in Brazil and confirms the need to examine urine during the course of reaching a diagnosis.

LA: Portuguese | At the Jockey Club of Sao Paulo, an 8-year-old Thoroughbred developed progressive locomotor incoordination over a period of about 20 days. Weakness of the hindquarters grew steadily worse and there was facial paralysis and nervous excitement terminating in lateral recumbency. PM examination revealed organs congested or haemorrhagic with fatty accumulation in the liver; brownish foci of the central nervous system in the region of the thalamus, hypothalamus and bulb; areas of granulomatous encephalomyelitis with nematodes present. Over 30 years during which 3540 PM examinations were recorded, this is the first case of parasitic encephalomyelitis. The foreign literature, however, cites some cases caused by Micronema deletrix.

LA: English | The study employed 12 healthy horses with no apparent signs of neurological or gastrointestinal disease and 55 horses suffering from grass sickness (GS). Fifteen of the cases were acute (AGS, < 2 days), 26 were subacute (SAGS, 2-7 days) and the remaining 14 were chronic (CGS, > 7 days). Hepatocellular and hepatobiliary damage was assessed. Based on histopathological analysis, enlarged hepatocytes; hepatocyte vacuolation that is indicative of steatosis; intrahepatocyte, canalicular and periportal deposition of pigments; frequent leukocyte infiltration and cholangitis were observed to occur even in some early cases of AGS. The AGS and SAGS groups displayed significantly increased levels of conjugated bilirubin, particularly in urine; but unconjugated bilirubin increased significantly in all the groups. Increased levels of bile acid in some individuals from each group, and significantly elevated levels of glutamate dehydrogenase in AGS and SAGS cases were also observed. These findings suggest that liver and biliary system dysfunction is present in horses suffering from GS and may be directly related to the pathogenesis of the disease.

Preliminary study. | Archivos-de-Zootecnia. 1993, 42: 156, 81-84; 6 ref. LA: Spanish LS: English | Blood was sampled from 18 Spanish horses 4-12 years old weighing 345-450 kg living in similar conditions and the liver of 11 horses from the same location which had died at 2 days to 18 years old was examined. Of the horses which had died, 8/11 showed some degree of fatty degeneration of the liver and 1 had hepatomegalia. Only 3 seemed to have a normal liver. There was no difference in activity of gamma-glutamyltransferase or of aspartate aminotransferase in blood between horses under and over 10 years old. Some of the horses showed a slight increase above normal in the activity of these enzymes. Digestible energy 30.05 Mcal daily (recommended value 16.5 Mcal daily), crude fibre 28.6% DM (18-22% DM) and phosphorus 31 g daily (14-18 g) intakes were excessive as were those for DM, digestible crude protein and calcium. It is concluded that excessive carbohydrate intake gave rise to liver damage.

LA: English LS: German | Effects of graded intensity exercise on plasma lipids was studied in Standardbred and Finnishbred Trotters. The rate of lipolysis indicated by the elevated plasma concentrations of glycerol increased parallel with the intensity of the trot in the Standardbreds, but not as clearly in the Finnishbred trotters. During the exercise plasma triglyceride concentration increased significantly and the increase correlated with the intensity of the exercise as well as the activity of lipolysis. Together with the increase in plasma triglycerides, there was a parallel increase in the pre-beta fraction of lipoproteins which suggests that the hepatic synthesis of triglycerides was increased. It was calculated that about one third of the NEFAs released in lipolysis during the high-intensity exercise is oxidized and the remainder is used for resynthesis of triglycerides. Since there were interstrain differences in the concentrations of triglycerides and glycerol after the high-intensity exercise it is suggested that the differences may be of some value in the estimation of recovery after submaximal exercise.

LA: English | The concentrations and fatty acid composition of the plasma free fatty acid, triacylglycerol and phospholipid fractions were determined in maternal and umbilical cord vein blood samples taken at parturition from 17 mares. Maternal and umbilical vein plasma free fatty acid concentrations were of a similar order and a positive correlation was found between the 2 values suggesting that the equine placenta is permeable to fatty acid. Substantial amounts of the essential fatty acids and their longer chain derivatives were seen in both umbilical vein plasma free fatty acid and phospholipid fractions supporting this view. Certain long chain polyunsaturated derivatives of the essential fatty acids found in the umbilical venous plasma phospholipid fraction were not seen in the maternal circulating lipids. The precursor fatty acids were readily available to both fetal and placental tissues and therefore must have been elongated and incorporated into phospholipid by either or both. Very small amounts of the essential fatty acids were found in adipose stores in the newborn foal and virtually no fat stores at all in the newborn foal liver.

LA: English | The incidence of hyperlipaemia in ponies is highest in mares in late gestation and then early in lactation. Plasma lipid and lipoprotein concentrations were measured to establish the metabolic basis for this and the lipoprotein composition of 6 healthy Shetland ponies was analysed before pregnancy, in the last 6 weeks of gestation and 1 month after foaling. In pregnant ponies, concentrations of cholesterol and triglyceride were increased because of increased concentrations of high density lipoproteins (HDL) and very low density lipoproteins (VLDL), respectively. The VLDL were significantly enriched in triglyceride and depleted of protein, with most cholesterol in the free rather than esterified form. These changes appeared to reflect increased hepatic triglyceride synthesis and VLDL secretion because the activities of lipoprotein lipase and hepatic lipase, the enzyme responsible for the catabolism of VLDL and their remnants, were unaltered. After foaling, the concentrations of triglyceride and VLDL decreased significantly because of increased lipoprotein lipase activity consistent with the induction of the enzyme in mammary tissue to provide for milk fat synthesis. Plasma cholesterol and HDL concentrations remained high and NEFA concentrations were significantly increased. The VLDL remained enriched in triglyceride but had normal cholesterol and protein compositions, although the mass of phospholipids was reduced. The changes in plasma VLDL concentration and composition found in the pregnant ponies mimicked those previously reported in ponies with hyperlipaemia and suggested a metabolic basis for the incidence of the disease in late gestation.

LA: Dutch LS: English | The study covered 103 widely assorted ponies with hyperlipaemia. Blood was sampled regularly. One treatment was with glucose 1 g/kg bodyweight by mouth twice daily and insulin 15 units by muscle. As a result the concentration of total lipid in blood and also the pH fell, lactate increased greatly and glucose rose. The ponies developed severe acidosis and nearly all died. In a second treatment ponies had on the odd days 100 g glucose by mouth twice and insulin 30 units by muscle and on the even days 100 g galactose once by mouth and insulin 15 units twice by muscle. All doses were increased by 50% for ponies weighing over 200 kg and for all with total lipid exceeding 8000 mg/100 ml. If they had severe acidosis they had 2 doses of 150 g galactose instead of the same amount of glucose on the first day. When total lipid fell below 3000 mg/100 ml, the ponies had on odd days glucose 75 g twice and insulin 15 units and on even days galactose 75 g once and insulin 10 units twice; all amounts were raised by 50% if the ponies were large. Acidosis and diarrhoea were treated. The supply of sugars was stopped when total lipid stayed <1000 mg/100 ml for several days and insulin was phased out over the next 3 days. Alternating use of both sugars reduced hyperlipaemia, pH rose and there was hardly any rise in lactate. Dissection of dead ponies showed that a number of organs were fatty, even if total blood lipid had become normal. The few liver studies made revealed no glycogen. Results were compared for ponies which survived or died, also for the clinically healthy and those given the first treatment. It was concluded that mares in late pregnancy with total lipid >3000 mg/100 ml were particularly at risk.

LA: French LS: English, Spanish | During May-November 1992, 146 cases of a fatal, sporadic, hepatic encephalopathy were reported in horse breeding centres of western France. The disease affected mares kept on permanent pasture, and was characterized clinically by an initial phase of icterus and photosensitization, followed by central nervous signs. 80% of cases died. Peak incidence was in July (56 cases). Virological tests were negative. No seroconversions for leptospirosis were detected. Histological examination of liver samples showed necrotizing hepatitis and steatosis. Herbage samples were negative for fungi, fungal spores and coumestrol. However, the white clover component of the samples had a high content (over 50%) of soluble nitrogenous matter and, in one case, a high content of hydrocyanic acid. PT: Journal-article AN: 932291220 >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Phil: However, we see conditions in animals where energy-dense feed [for example high-concentrate diets in cattle, or high-energy forced- feeding of Strasbourg geese] causes massive fat-infiltration into liver; liver fat content can rise to 20-40%, with swelling of the liver and great increase in serum liver enzymes. Jackie: I was wondering about the possibility of fatty liver in horses - any evidence you know of? And some horses (EPSM/PSSM) can only maintain normal muscle function on a pint of supplementary oil a day - that must have a downside. Phil: Such livers are under severe metabolic stress, with clinical consequences that include lowered immunity, laminitis/hoof- lameness [equivalent to " nail-bed " disorders in humans], infertility, indigestion and rumen acidosis [LV overacting on ST in cattle, not geese!], etc. Jaclie: Mind you, Chaihu Qing Gan Tan appeared to do roughly that to my horse. A Spleen tonic formula actually caused a gastric ulcer. Phil: Another COMMON situation with " NORMAL " feed occurs when cattle are on heavily fertilised grass. Mean N values in Irish grass are 3.5% DM, equivalent to crude protein values of 23%. Jackie: And sugars up to 40% in improved species like ryegrass - which has now been sown into many horse paddocks, or used for their hay. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Best regards, Email: < WORK : Teagasc Research Management, Sandymount Ave., Dublin 4, Ireland Mobile: 353-; [in the Republic: 0] HOME : 1 Esker Lawns, Lucan, Dublin, Ireland Tel : 353-; [in the Republic: 0] WWW : http://homepage.eircom.net/~progers/searchap.htm Quote Link to comment Share on other sites More sharing options...
