Phil >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Bensoussan A, Myers SP, Wu SM, O'Connor K. | Naturopathic and Western herbal medicine practice in Australia-a workforce survey. | Complement Ther Med. 2004 Mar;12(1):17-27. | The Centre for Complementary Medicine Research, University of Western Sydney, Locked Bag 1797, Penrith South DC, NSW 1797, Australia. | Background: Despite substantial growth in the use of complementary medicine, no comprehensive national study has been undertaken of the naturopathic and Western herbal medicine component of the healthcare workforce in Australia. This study aimed to examine the nature of these practices and this currently unregulated workforce in Australia. Methods: A comprehensive survey questionnaire was developed in consultation with the profession and distributed nationally to all members of the naturopathic and Western herbal medicine workforce. Results: The practices of herbal medicine and naturopathy make up a sizeable component of the Australian healthcare sector, with approximately 1.9 million consultations annually and an estimated turnover of $AUD 85 million in consultations (excluding the cost of medicines). A large proportion of patients are referred to practitioners by word of mouth. Up to one third of practitioners work in multidisciplinary clinics with other registered sectors of the healthcare community. The number of adverse events associated with herbal medicines, nutritional substances and homoeopathic medicines recorded in Australia is substantial and the types of events reported are not trivial. Data suggest that practitioners will experience one adverse event every 11 months of full-time practice, with 2.3 adverse events for every 1000 consultations (excluding mild gastrointestinal effects). Conclusion: These data confirm the considerable degree of utilisation of naturopathic and Western herbal medicine practitioners by the Australian public. However, there is a need to examine whether statutory regulation of practitioners of naturopathy and Western herbal medicine is required to better protect the public. | PMID: 15130568 [PubMed - in Process] Goel HC, Prasad J, Singh S, Sagar RK, Agrawala PK, Bala M, Sinha AK, Dogra R. | Radioprotective Potential of an Herbal Extract of Tinospora cordifolia. | J Radiat Res (Tokyo). 2004 Mar;45(1):61- 8. | Department of Radiation Biology, Institute of Nuclear Medicine and Allied Sciences. | A preparation of Tinospora cordifolia (RTc) administered i.p. (200 mg/kg b.w.) to strain " A " male mice 1 h before whole body gamma-irradiation was evaluated for its radioprotective efficacy in terms of whole body survival, spleen colony forming units (CFU), hematological parameters, cell cycle progression, and micronuclei induction. Preirradiation treatment with RTc rendered 76.3% survival (30 days), compared to 100% mortality in irradiated control and prevented radiation induced weight loss. On 10th postirradiation day, the endogenous CFU counts in spleen were decreased with increasing radiation doses 12.0 (5 Gy), 2.16 (7.5 Gy) and 0.33 (10 Gy) but pre-irradiation administration of 200 mg/kg b.w. of RTc increased CFU counts to 31.16, 21.83 and 3.00 respectively. Pre-irradiation RTc treatment could restore total lymphocyte counts (TLC) by the 15th day to normal. It also increased the S-phase cell population that was reduced following 2 Gy irradiation in a time dependent manner. 2 Gy irradiation-induced micronuclei were also decreased by a pre- irradiation administration of RTc from 2.9 to 0.52%. Because the radioprotective manifestation of RTc observed in several systems in experimental animals can be exploited for human applications. | PMID: 15133291 [PubMed - in Process] He N, Edeki T. | The Inhibitory Effects of Herbal Components on CYP2C9 and CYP3A4 Catalytic Activities in Human Liver Microsomes. | Am J Ther. 2004 May-Jun;11(3):206-12. | Departments of Pharmacology and Medicine, Morehouse School of Medicine, Atlanta, GA, USA. | Herbal medicines are widely consumed by patients in different clinical settings in the United States and all over the world. In this study, 7 herbal components ginsenosides Rb1, Rb2, Rc, and Rd (from ginseng quercetin) ginkgolides A and B (from ginkgo biloba) were investigated for their inhibitory effects on hepatic CYP2C9 and CYP3A4 catalytic activities in human liver microsomes. Tolbutamide 4-methylhydroxylation and testosterone 6beta-hydroxylation were used as index reactions of CYP2C9 or CYP3A4 catalytic activities, respectively. The metabolites of both reactions were measured by high-performance liquid chromatography and used as indicators of whether enzymes were inhibited or unaffected by these agents. Herbal components were studied at various concentrations (0.1, 1, 10, 100, 200 micromol/L). The herbal compounds investigated were capable of inhibiting CYP2C9 and CYP3A4 catalytic activities, but the potencies differed. Quercetin showed marked inhibitory effects on both tolbutamide 4- methylhydroxylation and testosterone 6beta- hydroxylation with IC(50) values of 35 and 38 micromol/L, respectively. Ginsenoside Rd also had significant inhibitory potency on both CYP2C9- and CYP3A4-mediated index reactions with IC(50) values of 105 and 62 micromol/L, respectively. Ginsenosides Rb1, Rb2, and Rc had limited inhibitory activities on both enzyme reaction systems, whereas the effects of ginkgolides A and B appeared negligible. It is concluded that the components of ginseng and ginkgo biloba screened are capable of inhibiting CYP2C9- and CYP3A4-mediated metabolic reactions. Our findings suggest that quercetin and ginsenoside Rd have the potential to interact with conventional medicines that are metabolized by CYP2C9 and CYP3A4 in vivo. | Hecker M, Volp A. | Tolerability of icelandic moss lozenges in upper respiratory tract diseases - multicentric drug monitoring study with 3,143 children - Article in German | Forsch Komplementarmed Klass Naturheilkd. 2004 Apr;11(2):76-82. | Engelhard Arzneimittel GmbH und Co. KG, Niederdorfelden, Germany. | Tolerability of Icelandic Moss Lozenges in Upper Respiratory Tract Diseases - Multicentric Drug Monitoring Study with 3,143 Children Background and Objective: Icelandic moss is a medical herb with therapeutic efficacy in inflammatory airway diseases. Although preparations based on the extract of this lichen have been marketed since the 19th century, their tolerability has not yet been investigated systematically. Patients and Methods: The tolerability of Isla-Moos® and Isla-Mint® lozenges and the changes of clinical symptoms during treatment were investigated in a post-marketing surveillance study performed in 300 predominantly pediatric practices in Germany. The preparations contained 80 and 100 mg, respectively, of an aqueous Icelandic moss extract. 3,143 children between 4 and 12 years of age who suffered from upper respiratory tract diseases received Isla-Moos® (n = 1,848) or Isla-Mint® (n = 1,295) over a period of 1-2 weeks; 61% of the children received 4-6 lozenges per day. Tolerability was evaluated by assessing adverse drug reactions (ADRs). Treatment success was assessed globally by the investigators and the patients' parents. The parents were also asked to rate their children's symptoms before and after treatment. Results: During the period of observation, 73 adverse events, most of which were related to the basic disease, were reported in 57 children (1.8%). In 6 children (0.2%) and 7 events (2x itching, 2x nausea, 1x abdominal pain, 1x heartburn, 1x burning in the mouth) a causal relationship with Icelandic moss extract could not be excluded, so that they were evaluated as ADRs. All ADRs subsided spontaneously during the period of observation. The incidence of ADRs was 1 event in 3,008 (95% confidence interval: 1,504- 7,019) treatment days. As regards clinical symptoms, 39% of the children were fully recovered and another 55% were improved by the end of the period of observation. Conclusions: During treatment of 4- to 12-year-old children with Isla-Moos® and Isla-Mint® lozenges only isolated, trivial, and transient adverse drug reactions were observed. The results thus confirm the good tolerability of both drugs and support a favorable risk-benefit assessment. Copyright 2004 S.

(2) To investigate the possibility of reducing toxicity of the herb combined with Rhizoma Coptidis (Huanglian). Methods: The 70% ethanol extract of the herb was fed to mice via gastric tube for 8 weeks. The blood was collected to assess liver and renal functions. The tissue samples of the liver, kidney and bladder were collected from executed animals for pathology examination. Results: The LD(50) with a 95% average trustable probability ( [Formula: see text] ) of AMA from Hanzhong (HZ) is [Formula: see text] g/kg. The weight of animals in the treatment group at a dose of 4g/kg raw drug, equivalent to 40 times of normal human dose in clinical prescription, remained the same as the control group ( [Formula: see text] ). On pathological examination, there were no morphological changes under light microscope in the liver and bladder. For the kidney, the renal toxicity was significantly reduced after using ethanol extract of R. coptidis to process HZ AMA in that there were no interstitial inflammation, formation of hyaline cast or regeneration of renal tubules. | PMID: 15138042 [PubMed - in Process] Huang ST, Yang RC, Chen MY, Pang JH. | Phyllanthus urinaria induces the Fas receptor/ligand expression and ceramide-mediated apoptosis in HL-60 cells. | Life Sci. 2004 Jun 4;75(3):339-51. | Chinese Herbal Pharmacy, Chang Gung Memorial Hospital, Tao-Yuan, Taiwan, ROC. | Phyllanthus urinaria (P. urinaria), a widely used herb medicine, was tested for the anticancer effect on human myeloid leukemia cells in this study. The water extract of P. urinaria induced the apoptosis of HL-60 cells as demonstrated by morphological change, DNA fragmentation and increased caspase-3 activity. However, normal human peripheral mononuclear cells remained viable under the same treatment. The P. urinaria-induced apoptosis of HL-60 cells was associated with the increased Bax gene expression and decreased Bcl-2 gene expression. In addition, the gene expressions of Fas receptor and Fas ligand, but not p53, were also induced in HL-60 cells dose- and time- dependently. The inhibitor of ceramide synthase, fumonisin B1, completely suppressed the apoptosis induced by P. urinaria and this inhibitory effect of fumonisin B1 could be eliminated by the addition of ceramide. It indicated that the activity of ceramide synthase is critical for the P. urinaria-induced apoptosis in HL-60 cells. The P. urinaria- induced apoptosis in HL-60 cells is mediated through a ceramide-related pathway. | PMID: 15135654 [PubMed - in Process] Ikegami F, Fujii Y, Satoh T. | Toxicological considerations of Kampo medicines in clinical use. | Toxicology. 2004 May 20;198(1-3):221-8. | Center for Environment, Health and Field Sciences, Chiba University, Kashiwanoha 6-2-1, Kashiwa 277-0882, Japan. | Kampo (Japanese herbal) medicines, produced by combining multiple crude drugs, almost all of plant origin but with some of animal or mineral origin, contain great many substances. Since Kampo medicine results from the combination of many substances, their effect is a combination of the various interactions of the constituent substances. It has been demonstrated that several potential side effects such as allergic reactions, diarrhea and vomiting may be experienced when administering Kampo medicine. In addition, it has been reported that Kampo medicine may have antagonistic or synergistic interactions with western drugs or with some foods such as grapefruit juice. Among the 210 medicinal prescriptions used in present-day Japan, the clinical uses and the acute, chronic and mutagenic toxicity of some Kampo medicines are described. Studies of some potential interaction between Kampo medicines and western drugs are also considered. | PMID: 15138045 [PubMed - in Process] Iten F, Saller R. | Fennel tea: risk assessment of the phytogenic monosubstance estragole in comparison to the natural multicomponent mixture - Article in German | Forsch Komplementarmed Klass Naturheilkd. 2004 Apr;11(2):104-8. | Abteilung fur Naturheilkunde, Departement fur Innere Medizin, Universitatsspital, Zurich, Schweiz. | Fennel Tea: Risk Assessment of the Phytogenic Monosubstance Estragole in Comparison to the Natural Multicomponent Mixture For centuries, fennel fruits have been used as traditional herbal medicine in Europe and China. For the treatment of infants and sucklings suffering from dyspeptic disorders, fennel tea is the drug of first choice. Its administration as a carminativum is practiced in infant care in private homes and in maternity clinics as well where it is highly appreciated for its mild flavor and good tolerance. The long standing positive experience is astonishingly contrasted by a recent statement of the German 'Bundesinstitut fur gesundheitlichen Verbraucherschutz und Veterinarmedizin' (BgVV, May 11, 2001), where consumers are adviced to reduce their intake of foods containing estragole and methyleugenol, e.g. tarragon, basil, anis, star anis, jamaica pepper, nutmeg, lemon grass as well as bitter and sweet fennel fruits for reasons of health. These warnings are based on experiments with rats and mice where estragole, a natural ingredient of fennel fruits, proved to be carcinogenic. Meanwhile, criticism arose amongst experts concerning the interpretation of these studies. The crucial points of criticism concern the transfer of data obtained in animal models to the human situation as well as the high doses of the applied monosubstance, which do not at all represent the amounts humans are exposed to as consumers of estragole-containing foods and phytopharmaceuticals. Furthermore, studies on estragole metabolism revealed at least quantitative differences between the estragole metabolism of mice and men. In addition, it has been shown that an agent when administered in its isolated form may have significantly different effects and side effects than the same agent applied as a constituent in naturally occuring multicomponent mixtures. Thus, a multicomponent mixture such as fennel tea contains various antioxidants known to be protective against cancer. These differences were not considered in the risk assessment. A well done risk assessment should be based on appropriate data collected in humans. Considering the long traditional use of fennel tea and the total lack of epidemiological and clinical studies indicating a well founded cancerogenic potential, the probability of a serious risk connected with the consumption of fennel tea seems to be negligibly small.

Though it was previously shown that tetrandrine causes a G1 blockade and apoptosis in various cell types, however, the mechanism by which tetrandrine initiates apoptosis remains poorly understood. In present study, we investigated the mechanisms of apoptosis induced by tetrandrine in U937 leukemia cells. Tetrandrine inhibited U937 cell growth by inducing apoptosis. After treatment of U937 cells with tetrandrine (10microM) for 24h, alteration of cell morphology, chromatin fragmentation, cytochrome c release, and caspase activation were observed. Tetrandrine also induced early oxidative stress, which resulted in activation of JNK, but not ERK and p38 MAPK. A broad-spectrum caspase inhibitor and antioxidants significantly blocked tetrandrine- induced caspase-3 activation. However, inhibition of the JNK activity with SP600125 did not block tetrandrine-induced apoptosis. Tetrandrine-induced apoptosis of U937 cells also required activity of PKC-delta, because pretreatment with a specific PKC-delta inhibitor greatly blocked tetrandrine-induced caspase-3 activation. In addition, the apoptotic response to tetrandrine was significantly attenuated in dominant-negative PKC-delta transfected MCF-7 cells, suggesting that PKC-delta plays an important role in tetrandrine-induced apoptosis and can induce caspase activation. These results suggest that tetrandrine induces oxidative stress, JNK activation, and caspase activation. However, JNK activation by ROS is not involved in the tetrandrine-induced apoptosis. In addition, tetrandrine induces caspase-dependent generation of a catalytically active fragment of PKC-delta, and this fragment also appears to play a role in the activation of caspases. | PMID: 15130759 [PubMed - in Process] Jiang XL, Cui HF. | Different therapy for different types of ulcerative colitis in China. | World J Gastroenterol. 2004 May 15;10(10):1513- 1520. | Department of Gastr-oenterology, Chinese PLA General Hospital of Jinan Military Command, 25 Shifanlu, Jinan 250031, Shandong Province, China. jiangxueliang678 | AIM: To study the different therapy for different types of ulcerative colitis (UC) in China. METHODS: Among 102 UC patients, 42 chronic relapse type UC patients were randomly divided into olsalazine sodium treatment group (n=21) and SASP group (n=21). Clinical effects and safety were observed in the 2 groups. Forty-two first episode type UC patients were randomly divided into Heartleaf houttuynia herb treatment group (n=21) and SASP group (n=21). Clinical effects were observed in the 2 groups while ultrastructure of colonic mucosa, ICAM-1 and the pressure of distant colon were studied in Heartleaf houttuynia herb group. Eighteen patients (8 males, 10 females) with refractory UC and unresponsive to high-dose prednisolone and sulfasalazine therapy more than one month were treated with Kangshuanling (7 200 U/d). Prednisolone was gradually stopped and sulfasalazine was maintained. Stool frequency, rectal bleeding, colonoscopy, general well- being, histology were observed and CD62p, CD63, CD54, Pgp-170 (flow cytometry), TXA2 (RIA), blood platelet aggregation rate and thrombosis length in vitro were assessed. RESULTS: In the 42 chronic relapse type UC patients, the overall clinical effects of olsalazine sodium group (complete remission in 16, improvement in 4, inefficiency in 1) were better than those of SASP group (complete remission in 10, improvement in 4, inefficiency in 7, P<0.05). Symptomatic remission of olsalazine sodium group (complete remission in 15, partial remission in 5, inefficiency in 1) was better than that of SASP group (complete remission in 10, partial remission in 5, inefficiency in 6, P<0.05). The colonoscopic remission of olsalazine sodium group(complete remission in 11, partial remission in 9, inefficiency in 1) was better than that of SASP group (complete remission in 7, partial remission in 8, inefficiency in 6, P<0.05). The histologic remission of olsalazine sodium group (complete remission in 13, partial remission in 7, inefficiency in in 1) was better than that of SASP group (complete remission in 6, partial remission in 10, inefficiency in 5, P<0.05). The side effects of gastrointestinal tract in olsalazine sodium group were less than those of SASP group except for frequency of watery diarrhea. No other side effects were observed in olsalazine sodium group while ALT increase, WBC decrease and skin eruption were observed in SASP group. Two patients relapsed in olsalazine sodium group while 8 cases relapsed in SASP group during the flow-up period (from six months to one year). In the 42 first episode type UC patients, the clinical effect of Heartleaf houttuynia herb group (complete remission in 20, 95.2%; improvement in 1, 4.8%) was better than that of SASP group (complete remission in 15, 72.4%, improvement in 5, 23.8%; inefficiency in 1, 3.8%, P<0.01). The time of stool frequency recovering to normal (5.6+/-3.3 d), and blood stool disappearance (6.7+/-3.8 d) and abdominal pain disappearance (6.1+/-3.5 d) in Heartleaf houttuynia herb group was all shorter than that in SASP group (9.5+/-4.9 d, 11.7+/-6.1 d, 10.6+/-5.3 d, P<0.01). Heartleaf houttuynia herb could inhibit the epithelial cell apoptosis of colonic mucous membrane and the expression of ICAM-1 (45.8+/-5.7% vs 30.7+/- 4.1%, P<0.05). Compared with normal persons, the mean promotive speed of contraction wave stepped up (4.6+/-1.6 cm/min vs 3.2+/-1.8 cm/min, P<0.05) and the mean amplitude of the wave decreased (14.2+/-9.3 kPa vs 18.4+/-8.0 kPa, P<0.05) in active UC patients. After treatment with Heartleaf houttuynia herb, these 2 indexes improved significantly (17.3+/-8.3 kPa, 3.7+/- 1.7 cm/min, P<0.05). In normal persons, the postprandial pressure of sigmoid (2.9 +/-0.9 kPa) was higher than that of descending colon (2.0+/-0.7 kPa) and splenic flexure (1.7+/-0.6 kPa), while the colonic pressure (1.5+/-0.5 kPa, 1.4+/-0.6 kPa, 1.3+/-0.6 kPa) decreased significantly (P<0.05) in active UC patients. After treatment with Heartleaf houttuynia herb, the colonic pressure (2.6+/-0.8 kPa, 1.8+/-0.6 kPa, 1.6+/-0.5 kPa) recovered to normal. The pain threshol Heartleaf houttuynia herb, the colonic pressure (2.6 & plusmn;0.8 kPa, 1.8 & plusmn;0.6 kPa, 1.6 & plusmn;0.5 kPa) recovered to normal. The pain threshold of distant colon (67.3 & plusmn;18.9 mL) in active UC patients decreased significantly compared with that of normal persons (216.2 & plusmn;40.8 mL, P & lt;0.05) and recovered to normal after treatment with Heartleaf houttuynia herb(187.4 & plusmn;27.2 mL, P & lt;0.05). In the 18 refractory UC patients with platelet activation, after more than 4 wk of combined Kangshuanling and sulfasalazine therapy, 16 patients achieved clinical remission, with a highly significant statistical difference (P & lt;0.01) between pre- and post-treatment mean scores for all disease parameters: stool frequency (8.2/d vs 1.6/d), rectal bleeding (score 2.7 vs 0.3), colonoscopy (score 2.6 vs 1.1), histology (score 12.0 vs 5.0), general well being (score 4.0 vs 0.6) and CD62p (8.0 & plusmn;3.1% vs 4.1 & plusmn;1.8%), CD63 (6.3 & plusmn;2.1% vs 3.2 & plusmn;1.6%), TXA2 (548 & plusmn;85 ng/L vs 390 & plusmn;67 ng/L), platelet aggregation rate (43.2 & plusmn;10.7% vs 34.8 & plusmn;8.1%), thrombosis length in vitro (2.3 & plusmn;0.6 cm vs 1.8 & plusmn;0.3 cm), CD54 in blood (26.9 & plusmn;6.9% vs 14.4 & plusmn;5.1%), CD54 in tissues (51.1 & plusmn;6.2% vs 23.1 & plusmn;4.1%), Pgp-170 in blood (18.9 & plusmn;3.9% vs 10.4 & plusmn;2.7%), Pgp-170 in tissues (16.5 & plusmn;3.2% vs 10.2 & plusmn;2.3%, P & lt;0.01 or 0.05). CONCLUSION: Based on the characteristics of UC cases in China, different therapy should be given to different types of UC with expected satisfactory results. | PMID: 15133864 [PubMed - as supplied by publisher] Kirui PK, Cameron J, Benghuzzi HA, Tucci M, Patel R, Adah F, Russell G. | Effects of sustained delivery of thymoqiunone on bone healing of male rats. | Biomed Sci Instrum. 2004;40:111-6. | Jackson State University, Jackson, MS 3921, USA. | The use of natural products as an alternative to conventional treatment in healing and treatment of various diseases has been on the rise in the last few decades. Nigella sativa, a natural herb has long been used as a natural medicine for treatment of many acute, as well as, chronic conditions. These include diabetes, hypertension and dermatological conditions. The specific objectives of this study were: (1) to successfully deliver the active component of black seed called Thymoqiunone (TMQ) at sustained level using TCPL drug delivery system; (2) to evaluate the physiological responses associated with sustained delivery of TMQ in femoral defect animal model (bone healing). A total of 15 adult male rats were randomly divided into three equal groups. Animals in group I served as controls, animals in group II served as sham while animals in group III served as experimental group (femur defect model). Group III animals were surgically implanted with TCPL capsule loaded with 0.02 grams of TMQ and 200 mg vancomycin. Blood samples, x-rays and body weights were collected and recorded weekly. At the end of 30 days post treatment, all animals were sacrificed and vital as well as reproductive organs were collected and analyzed histopathologically. Metabolic biochemical markers were also evaluated. The results of this study revealed the following: (i) gross anatomical observation indicated difference in healing pattern of animals in group III compared to those in group II (sham); (ii) no significant differences in all levels of cholesterol, proteins, malondialdehyde and alkaline phosphatase in all groups; (iii) no significant differences in the wet weights of vital as well as reproductive organs in all the groups. In conclusion, it appears that sustained levels of TMQ can enhance bone healing with little or no side effects on major vital and reproductive organs. | PMID: 15133944 [PubMed - in Process] Leach MJ. | A critical review of natural therapies in wound management. | Ostomy Wound Manage. 2004 Feb;50(2):36-40, 42, 44-6 passim. | School of Nursing and Midwifery, University of South Australia, North Terrace, Adelaide, South Australia 5000.

Also referred to as unconventional, alternative, and complementary, these therapies often are derived from natural sources and facilitate improvements in health and well being by supporting innate healing processes of the body. Although the application of natural therapies in wound management is still in its infancy, several--honey, larval therapy, aromatherapy, herbal medicine, homeopathy, nutrition, and mind-body-spirit techniques--are demonstrating potential benefit in the management of acute and chronic wounds. Existing evidence of safety and effectiveness is predominantly based on the results of in vivo studies; confirmation from well-designed clinical trials is deficient. Consequently, clinical research is needed to examine these therapies to address the escalating incidence of chronic wounds in a climate of increasing healthcare costs. | PMID: 15129611 [PubMed - in Process] Li SS, Li HY, Piao YA, Liu DL, Tian WJ, Dong YM. | The anti-respiratory syncytial virus effect of an active compound (AP3) from a Chinese medicinal herb-Herba patriniae in vitro - Article in Chinese | Zhonghua Liu Xing Bing Xue Za Zhi. 2004 Feb;25(2):150-3. | College of Public Health, Harbin Medical University, Harbin 150001, China. | OBJECTIVE: To study the effect on anti-respiratory syncytial virus of an active compound (AP3) from a Chinese medicinal herb- Herba patriniae in vitro. METHODS: Active component of herba patriniae (AP3) was extracted and its anti-respiratory syncytial virus (RSV) effect was tested. A water soluble substance (AP3) was isolated from a Chinese herb Herba patriniae, by hot water extraction, ethol precipitation and gel permeation column chromatography. The cytotoxicity of AP3 was tested by adding it to HeLa cells directly. Its effect against RSV was estimated by CPEI assay while ribavirin was used as positive control. RESULTS: Chemical test showed that the nature of substance AP3 was polysaccharide. The median cytotoxic concentration (TC(50)) of AP3 was 11.45 mg/ml by morphological observation and the median effective concentration (50% effective concentration, EC(50)) of it against replication of the long strain of RSV in HeLa cells was 0.0986 mg/ml. The Therapeutic index (TI = TC(50)/EC(50)) of AP3 was 116.12, much higher than the TI of herba patriniae (AP1) (TI = 59.26) and ribavirin (TI = 53.45). Moreover, AP3 gave a dose-dependent response in inhibiting RSV. In the assay, the effect of AP3 against RSV growth was also tested. In addition, the effect of AP3 on virus growth, AP3 inhibited replication of RSV in HeLa cells, when added at 0 h, 2 h, 4 h after virus infection, were also tested. CONCLUSION: This study suggested that the AP3 exerted an obvious inhibitory effect to RSV in HeLa cell culture. This study furnished a reliable evidence for development of a new antiviral drug. | PMID: 15132871 [PubMed - in Process] Limsong J, Benjavongkulchai E, Kuvatanasuchati J. | Inhibitory effect of some herbal extracts on adherence of Streptococcus mutans. | J Ethnopharmacol. 2004 Jun;92(2-3):281-9. | Department of Pharmacology, Faculty of Dentistry, Chulalongkorn University, Henri- Dunant Road, Bangkok 10330, Thailand. | The objective of this study was to investigate the inhibitory effect of the crude extracts from some herbs on adherence of Streptococcus mutans (S. mutans) ATCC 25175 and TPF-1 in vitro. Six herbs, Andrographis paniculata; Cassia alata; Chinese black tea (Camellia sinensis); guava (Psidium guajava); Harrisonia perforata and Streblus asper, were extracted with 50 or 95% ethanol and dried. Herbal extracted solution at 0.5% concentration (w/v) was initially tested for bacterial adherence on glass surfaces. In order to identify type and effective concentration of the extracts, the extracts that showed the inhibition on glass surfaces were then tested on saliva-coated hydroxyapatite by the use of radiolabeled bacteria. To study the mechanism of action, the effect of the extracts at such concentration on glucosyltransferase and glucan-binding lectin activities were examined. It was found that all extracts, but Streblus asper, showed significant inhibitory effect on bacterial adherence to glass surfaces. For the saliva-coated hydroxyapatite adherence assay, Andrographis paniculata, Cassia alata, Chinese black tea and Harrisonia perforata could inhibit adherence of S. mutans ATCC 25175. Chinese black tea was the strongest inhibitor followed by Andrographis paniculata, Cassia alata and Harrisonia perforata, respectively. For S. mutans TPF-1, adherence inhibition was observed from Andrographis paniculata and Cassia alata at similar levels. The lowest concentrations of the extracts that inhibited the adherence at least 50% were 0.5% of Andrographis paniculata, 0.5% of Cassia alata, 0.3% of Chinese black tea and 0.5% of Harrisonia perforata for S. mutans ATCC 25175. For S. mutans TPF-1, the effective concentrations were 0.5% of Andrographis paniculata and 0.4% of Cassia alata. All extracts at such concentrations decreased the activity of glucosyltransferase from both strains. Only Andrographis paniculata and Cassia alata eliminated or decreased the activity of glucan-binding lectin from both strains. These findings suggested that Andrographis paniculata, Cassia alata, Chinese black tea and Harrisonia perforata could inhibit adherence of S. mutans ATCC 25175, while Andrographis paniculata and Cassia alata had an effect on S. mutans TPF-1 in vitro at the concentrations employed in this study. | PMID: 15138013 [PubMed - in Process] MacDonald D, VanCrey K, Harrison P, Rangachari PK, Rosenfeld J, Warren C, Sorger G. | Ascaridole-less infusions of Chenopodium ambrosioides contain a nematocide(s) that is(are) not toxic to mammalian smooth muscle. | J Ethnopharmacol. 2004 Jun;92(2-3):215-21. | Department of Medicine, Hons. Biology- Pharmacology Coop Programme, McMaster University, Hamilton, Ont., Canada. | Infusions of Chenopodium ambrosioides (L.) have been used for centuries in the Americas as a popular remedy against intestinal worm infections. The essential oil of Chenopodium ambrosioides contains high levels of ascaridole, which is a potent anthelmintic, but which has also been responsible for human fatalities, leading to its disuse. Almost 90% of the nematocidal activity of Chenopodium ambrosioides infusions was due to a hydrophilic component different from ascaridole. Synthetic ascaridole and the ascaridole from infusions, extracted into hexane, caused a reduction of carbachol-induced contractions in rat gastrointestinal smooth muscle at concentrations required to kill Caenorhabditis elegans (L.). The herbal infusion and the ascaridole-free hexane-extracted aqueous residue of the above infusion, at nematocidal concentractions, had no detectable effect on smooth muscle contraction in the above system. It would appear that the traditional form of useage of Chenopodium ambrosioides infusions as a vermifuge is safer than the use of the herb's essential oil. | PMID: 15138003 [PubMed - in Process] Makino T, Inagaki T, Komatsu K, Kano Y. | Pharmacokinetic Interactions between Japanese Traditional Medicine (Kampo) and Modern Medicine (III).Effect of Sho-seiryu-to on the Pharmacokinetics of Azelastine Hydrochloride in Rats. | Biol Pharm Bull. 2004 May;27(5):670-3. | Department of Kampo Medicinal Science, Hokkaido College of Pharmacy. | Sho-seiryu-to (SST) is widely used herbal formula in Japanese traditional medicine (kampo) to treat allergic diseases. Since Japanese physicians frequently prescribe this formula combined with azelastine hydrochloride, one of anti-histamine and anti- allergic medicines, we evaluated the pharmacokinetic interactions between SST and azelastine hydrochloride in rats to obtain the drug information for the prevention from disadvantage or adverse effects by their combined therapy. Oral administration of SST did not influence the plasma concentration profile of azelastine after its intravaneous injection, suggesting that SST would not change the activities of metabolic enzymes such as cytochrome P450s. However, maximum concentration (C(max)) of azelastine after oral administration of azelastine hydrochloride was significantly reduced and mean residence time (MRT) was significantly lengthened when SST was orally administered at 20 times amount of human daily dosage. There was not significant difference in the area under the plasma concentration-time curve (AUC), suggesting that SST might delay the absorption of azelastine without affecting the extent of bioavailability. Since this delay was independent of ephedrine that is a main constituent of SST and that a suppressor for gastric transit, SST might form unsoluble complex with azelastine to reduce its absorption. At the double of human daily dose, SST did not made the absorption of azelastine delay. The possibility that SST reduce the absorption of azelastine hydrochloride could not be denied completely, however, it is suggested that SST would not cause pharmacokinetic interaction with azelastine hydrochloride clinically. | PMID: 15133242 [PubMed - in Process] Neurauter G, Wirleitner B, Schroecksnadel K, Schennach H, Ueberall F, Fuchs D. | PADMA 28 modulates interferon-gamma-induced tryptophan degradation and neopterin production in human PBMC in vitro. | Int Immunopharmacol. 2004 Jun;4(6):833-9. | Institute of Medical Chemistry and Biochemistry, Leopold Franzens University, Innsbruck, Austria. | Tibetan herbal remedy PADMA 28 revealed promising results to support treatment of intermittent claudication, atherosclerosis and chronic hepatitis. The remedy was confirmed to be closely linked with anti- and pro-oxidative properties in vitro. In this study, effect of PADMA 28 was investigated in stimulated and unstimulated human peripheral blood mononuclear cells (PBMC) in vitro. Neopterin production and tryptophan degradation were measured in supernatants of PBMC in the presence or absence of mitogens phytohaemagglutinin (PHA) and concanavalin A (Con A). Stimulation of PBMC induced neopterin formation and tryptophan degradation (p<0.001 compared to unstimulated PBMC), and PADMA 28 inhibited both immunobiochemical effects (p<0.001) in a concentration-dependent manner. Higher concentrations of PADMA 28 were more effective and were able to completely block the pathways induced upon mitogenic stimulation. Data allow to conclude that PADMA 28 is able to inhibit immunobiological effects in stimulated PBMC in vitro. The suppression of neopterin production and tryptophan degradation suggests a specific influence on biochemical pathways induced by Th1- type cytokine interferon-gamma. | PMID: 15135323 [PubMed - in Process] Park WH, Shin SS, Lee YC, Kim CH. | The inhibitory effects of Silso-San-Gami on atherosclerosis in KHC rabbits. | Thromb Res. 2004;113(3-4):235-241. | Department of Biochemistry, Molecular Biology and Diagnostics, Dongguk University College of Oriental Medicine and National Research Laboratory for Glycobiology, Korean Ministry of Science and Technology, Sukjang-Dong 707, Kyungju City, Kyungbuk 780-714, South Korea. | Silsosangami is a dried decoction of a mixture of seven Korean herbal medicines, consisting of Typhae pollen, Pteropi faeces, Paeoniae radicis rubra, Cnidii rhizoma, Persicae semen, Carthami flos, and Curcumae tuber. The inhibitory effect of this traditional herbal medicine, Silsosangami-water extract (SSG), on the progression of the atherosclerotic diseases was examined using the spontaneous familial hypercholesterolemia (FH) model, Kurosawa and Kusanagi-hypercholesterolemic (KHC) rabbits. Changes in blood chemistry, pathology and low-density lipoprotein (LDL) oxidation were measured in a control group and a SSG- administrated group. In the control group, the area of atheromatous aortic plaques progressed between 4 weeks (30.43%) and 8 weeks (47.48%). This progressin of atherosclerotic disease was not observed in the SSG-treated group between 4 weeks (22.65%) and 8 weeks (23.23%). Antioxidative effects on LDL were observed in the SSG group at 12 and 14 weeks. SSG improved hypercholestrolemia in the KHC rabbits. These results suggest that SSG has inhibitory effects on the development of atheromatous plaques in spontaneous FH model rabbits. The antioxidative effects of SSG on LDL appear to be the source of the beneficial effects observed in this study. | PMID: 15140588 [PubMed - as supplied by publisher] Peng CH, Tseng TH, Liu JY, Hsieh YH, Huang CN, Hsu SP, Wang CJ. | Penta-acetyl geniposide-induced C6 glioma cell apoptosis was associated with the activation of protein kinase C-delta. | Chem Biol Interact. 2004 Apr 15;147(3):287-96. | Institute of Biochemistry, Chung Shan Medical University, No. 110, Section 2, Chien Kuo N. Road, Taichung 402, Taichung, Taiwan, ROC. | Herbal medicine has been utilized to treat a variety of diseases, including cancer. On the other hand, disturbance of apoptosis is often observed in cancer cells. It has been reported that protein kinase C (PKC) isoforms are involved in the signaling of apoptosis. In the present study, we investigate the antitumor effect and possible mechanism of a herbal-originated product, (Ac)(5)GP. We demonstrate that (Ac)(5)GP treatment results in DNA fragmentation of C6 glioma cells dose-dependently. Stimulated by (Ac)(5)GP, PKCdelta and PKCzeta were activated and translocated to the cell membrane fraction. Flow cytometry analysis showed that PKCdelta, but not PKCzeta inhibition blocks the (Ac)(5)GP- induced apoptosis by decreasing the cell population of sub G1 peak. However, the mRNA levels of PKCdelta and PKCzeta were not altered by (Ac)(5)GP-induced glioma cell apoptosis. These results suggested that the treatment of (Ac)(5)GP induces apoptosis of tumor cells through the activation but not the synthesis of PKCdelta. | PMID: 15135084 [PubMed - in Process] Takahashi T, Takasuka N, Iigo M, Baba M, Nishino H, Tsuda H, Okuyama T. | Isoliquiritigenin, a flavonoid from licorice, reduces prostaglandin E(2) and nitric oxide, causes apoptosis, and suppresses aberrant crypt foci development. | Cancer Sci. 2004 May;95(5):448-53. | Department of Natural Medicine and Phytochemistry, Meiji Pharmaceutical University, Kiyose-shi, Tokyo 204-8588, Japan. okuyama | Isoliquiritigenin (ILTG), a flavonoid group compound, exists in some foodstuffs and herbal medicines such as licorice (Glycyrrhiza uralensis Fisher). Previously, we showed that ILTG can suppress azoxymethane (AOM)-induced colon carcinogenesis in ddY mice. In the present report, we present evidence that ILTG markedly decreases both prostaglandin E(2) (PGE(2)) and nitric oxide (NO) production in RAW264.7 mouse macrophage cells. The decrease of PGE(2) was dependent on cyclooxygenase-2 (COX-2) expression and the decrease of NO appeared due to a decrease in inducible nitric oxide synthase (iNOS) protein expression. In mouse and human colon carcinoma cells, ILTG treatment suppressed cell growth and caused apoptosis. Furthermore, in vivo administration of ILTG inhibited the induction of preneoplastic aberrant crypt foci (ACF) in the male F344 rat colon. Our results suggest that ILTG is a promising chemopreventive agent against colon carcinogenesis. | PMID: 15132774 [PubMed - in Process] >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> 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...
