دیابت ملیتوس یک اختلال متابولیکی مزمن است که علت آن نقص در ترشح انسولین (نوع i) یا فعالیت انسولین در سطح رسپتورها و یا هردو (نوع ii) است. از دیرباز گیاهان دارویی در درمان بیماری دیابت بکار رفته اند. اما بررسی علمی اثر بخشی و عوارض احتمالی این گیاهان دارویی از اهمیت زیادی برخوردار است. مشخص شده اکثریت گیاهان دارویی که در درمان دیابت استفاده می شوند دارای اجزا فعال بیولوژیکی (آلکالوئیدی، فلاوونوئ...
Introduction Reduced glutathione, most commonly called glutathione or GSH, is a relatively small molecule ubiquitous in living systems. Occurring naturally in all human cells, GSH is a water-phase orthomolecule. Its intracellular depletion ultimately results in cell death and its clinical relevance has been researched for decades. GSH is the smallest intracellular thiol (–SH) molecule. Its high...
introduction: during spermiogendsis, sperm chromatin histones are replaced by protamine. after fertilization, the sprem nucleus is decondenced by glutathione (gsh). in this survey, we study the effect of various concentrations of gsh on human in vitro sperm decondensation. material and methods: after preparation and analysis of semen samples, sperm pellet was washed by ham's f-10 medium twice a...
The objective of this study was to evaluate the concentrations total (T-GSH), oxidised (GSSG) and reduced (GSH) glutathione in blood dairy cows, assess relationships phase number lactation, milk production, body condition score (BCS) selected biochemical parameters on its concentrations. We analysed 79 samples whole from Holstein cows. concentration assessed by spectrophotometric enzymatic meth...
background: melatonin is a free radical scavenger. it has also antioxidant effects through its stimulatory actions on antioxidant system. objective: we conducted this study to examine the effect of different oral doses of melatonin on liver tissue. methods: we used 42 rats—6 rats in each group. group i served as the control group; group ii rats were pretreated with only melatonin; group iii was...
Glutathione in its reduced form (GSH) is an antioxidant and also is involved in pheomelanin formation. Thus, it has been long believed that GSH has a skin whitening effect. However, its actual or direct effect is unproven. We evaluated the anti-melanogenic effects of GSH and its derivatives in vitro. We examined change of melanogenesis and its related proteins by GSH itself and its derivatives,...
Human liver glutathione S-transferases (GSH S-transferases) were fractionated into cationic and anionic proteins. During fractionation with (NH4)2SO4 the anionic GSH S-transferases are concentrated in the 65%-saturated-(NH4)2SO4 fraction, whereas the cationic GSH S-transferases separate in the 80%-saturated-(NH4)2SO4 fraction. From the 65%-saturated-(NH4)2SO4 fraction two new anionic GSH S-tran...
The present study reports data on absorption of orally administered glutathione (GSH) in rat jejunum and in other organs, and the possible role of specific transport systems of GSH and gamma-glutamyltranspeptidase (EC 2.3.2.1; gamma-GT) activity. GSH levels were measured simultaneously in various organs after oral GSH administration to untreated rats and rats treated with L-buthionine sulfoximi...
