Guest guest Posted August 25, 2006 Report Share Posted August 25, 2006 Estrogen Overload In Young Girls In a recent study of 17,077 American girls, at age three, 3% of African-American girls and 1% of white girls showed breast and/or pubic hair development. At age seven, 27.2% of the former and 6.7% of the latter showed such secondary development. At age eight 8, 48.3% of African American and 14.7% of white girls exhibit such development. Amazingly, three percent of three-year old girls also showed such precocious developemnt. This indicates a tremendous estrogenic overload and no one can predict what kind of trouble it spells for those girls.79 Estrogenic activities have been shown in chemicals in common use, including pesticides, plastics, petroleum products, polystyrene, and PAHs (polycyclic aromatic hydrocarbons).80,81 Chemical companies usually pooh-pooh the health hazards of their chemicals, claiming that minute amounts of are safe. However, in a recent study, some plastic compounds were shown to have hormonal activity at concentrations as low as two parts per billion. The author discussed this serious issue in his book RDA: Rats, Drugs and Assumptions.67 To complex layers of hormonal dysregulations must be added the impact of many environmental pollutants that often goes unrecognized. The studies of endometriosis in Rhesus monkey following chronic exposure to 2,3,7,8-tetrachlorodibenzo-e-dioxin by Rier et.al..82 are of special interest. Endometriosis occurs in Rhesus monkeys spontaneously and resembles its human counterpart, both pathologically and clinically. Endometriosis is generally believed to be caused by estrogen dysregulation, and the role of environmental pollutants in its pathogenesis is rarely appreciated. Rier et al observed a direct dose-response correlation between chronic dioxin exposure and the incidence and severity of endometriosis in Rhesus monkeys. Specifically, they documented the presence of endometriosis with laparoscopy and biopsy in 71% of the exposed (25 ppt) monkeys while similar lesions were encountered in only 33% of control monkeys not exposed to dioxin. There are several target genes for the action of dioxin, including several growth regulatory genes involved in cell differentiation and inflammatory response. Notable among them are genes for cytochrome P-450, plasminogen activator inhibitor-2, and interleukin-1b. In a related study, a higher incidence of endometriosis in humans was correlated with exposure to PCBs.83 Dioxin and PCBs belong to an ever-lengthening list of pesticides and industrial pollutants that have been clearly shown to cause a wide range of hormonal dysregulation in humans, mammals, birds and fish.84 It is noteworthy in this context that the World Health Organization in 1990 reported the average per person daily dioxin intake of 133 picograms (mainly through polluted fish, meat, and poultry) in industrialized countries. The data strongly suggested that maternal exposure to dioxins before and during pregnancy can result in fetal mortality with overt effects on the mother.85 It may be added here that dioxin binds to eryl hydrosulfate receptors and forms adducts directly with DNA to cause its toxicity.86 5.Empirical Eevidence of Functional Inter-Relationship and Interdependences of Gonadal and Nongonadal Hormones Empirical experience with patients with CFS, fibromyalgia, and chronic autoimmune disorders makes it clear that disorders of nongonadal endocrine systems, such as thyroid and adrenal glands, cannot be separated from those of seemingly gonadal origin. The data for 24-hour urinary excretion of adrenal metabolites and selected data for thyroid hormones are included in this article to underscore that point. Indeed, in the amenorrhea subgroup, all 12 patients showed clearly abnormal urinary profiles. http://garynull.com/cms/index.php/plain/documents/amenorrhea_oligomen orrhea_and_polymenorrhea_in_cfs_and_fibromyalgia_are_caused_by_oxidat ive _____________ JoAnn Guest mrsjoguest www.geocities.com/mrsjoguest/Genes Quote Link to comment Share on other sites More sharing options...
