DHEA: Dehydroepiandrosterone
DHEA: Dehydroepiandrosterone Joseph Pepping, Pharm.D. [Am J Health-Syst Pharm 57(22):2048-2056, 2000. © 2000 ASHP, Inc.] Introduction Dehydroepiandrosterone (DHEA) and its active metabolite, DHEA sulfate (DHEAS), are endogenous hormones synthesized and excreted primarily by the zona reticularis of the adrenal cortex in response to adrenocorticotropic hormone. The exact mechanism of action and clinical role, if any, of DHEA and DHEAS remain unclear. Epidemiological data indicate an inverse relationship between serum DHEA and DHEAS levels and the frequency of cancer, cardiovascular disease (in men only), Alzheimer's disease and other age-related disorders, immune function, and progression of HIV infection. [1] Animal (primarily rodent) studies have suggested many beneficial effects of DHEA, including improved immune function and memory and prevention of atherosclerosis, cancer, diabetes, and obesity. Many of the benefits seen in animal studies have yet to be shown in humans. [1-3] Uses Clinically substantiated (yet still controversial) uses of DHEA include replacement therapy in patients with low serum DHEA levels secondary to chronic disease, adrenal exhaustion, or corticosteroid therapy; treating systemic lupus erythematosus (SLE), improving bone density in postmenopausal women; improving symptoms of severe depression; improving depressed mood and fatigue in patients with HIV infection; and increasing the rate of reepithelialization in patients undergoing autologous skin grafting for burns. [1,4-8] Other possible uses (with some supporting clinical studies) include enhancing the immune response and sense of well-being in the elderly, decreasing certain cardiovascular risk factors, and treating male erectile dysfunction. [4,8-12] Use of DHEA to slow or reverse the aging process, improve cognitive function, promote weight loss, increase lean muscle mass, or slow the progression of Parkinson's disease and Alzheimer's disease is clinically unsubstantiated. -

At 12 weeks post-ovariectomy, the effects of different doses of chrysin (0.5, GABAA 1, 2, and 4 mg/kg) were evaluated in the elevated plus maze, light/dark test, and locomotor activity test, and Oophorectomy comparisons were made with the clinically effective anxiolytic diazepam. The participation of GABA receptors Ovariectomy A in the actions of chrysin was explored by pretreating the rats with the noncompetitive GABA chloride ion Surgical menopause A channel antagonist picrotoxin (1 mg/kg). The results showed that chrysin (2 and 4 mg/kg) reduced anxiety-like behavior in both the elevated plus maze and light/dark test, and these effects were similar to diazepam. -

Molecular understanding of ligand- basophils, enterochromaffin cells and probably also in some receptor interaction is obtained by combining pharmacology specific neurons. Mast cell histamine plays an important role in (signal transduction, proliferation), molecular biology, receptor the pathogenesis of various allergic conditions. After mast cell modelling and the synthesis and identification of new ligands. degranulation, release of histamine leads to various well-known symptoms of allergic conditions in the skin and the airway system. In 1937, Bovet and Staub discovered compounds that antagonise the effect of histamine on these allergic reactions.3 Ever since, there has been intense research devoted towards finding novel ligands with (anti-) histaminergic activity.
