conclusions the results of this study supported the potential protective effects of zncl2 on rat kidney tissues against cdcl2 toxicity. results in contrast to the animals that received zncl2, cdcl2 induced a dose-dependent elevation in bun, creatinine, and mda in those without zncl2 pretreatment. zinc chloride had significantly decreased all biochemical parameters and protected kidney cells aga...
vanadium is quantitatively retained on 2-nitroso-1-naphhthol-4-sulfonic acid tetradecyldimethlbenzyammonium chloride onto microcrystalline naphthalene in the ph range of 3.0-4.0 from a large volume of aqueous solutions of various alloys and synthetic samples. after filtration, the solid mass consisting of the vanadium complex and naphthalene was dissolved with 5.0 ml of dimethylformamide and th...
در بخش اول این کار تحقیقاتی بطری های نوشابه از جنس پلی(اتیلن ترفتالات) (pet) با روش گلیکولیز توسط اتیلن گلیکول(eg) و در حضور کاتالیزورهای زیست سازگارزیرکونیل کلرید(zirconyl chloride)(zrocl2)، بیسموتکلرید(bismuth chloride)(bicl3)و سدیم کربنات(sodium carbonate)((na2co3به منظور تولید بیس(2-هیدروکسی اتیل ترفتالات) (bhet) مورد مطالعه قرار گرفتند. تحت شرایط عملیاتی متفاوت از قبیل دما( ?c 198-185)، زم...
chemical pollutants presence in water may induce severe ecological consequences and consequently affecting aquatic ecosystems integrity. heavy metals are dangerous pollutants for aquatic inhabitants that have a great stability. heavy metals contamination (pollution) of the surface waters happens widely by discharge of mill effluents. the objective of the present study was to determine the 50% l...
the present study deals with the oral supplementation with (50, 100 and 150 ?g/ml) synergetic effect of potassium and magnesium chloride on the fat body glycogen, protein, total lipids and haemolymph trehalose, protein of fifth instar larvae of bombyx mori l (lepidoptera: bombycidae). the observed parameters significantly increased in all the treated groups when compared with those of the corre...
introduction: aluminum is known as a neurotoxic element which causes neurodegeneration, learning deduction and movement disorders. aluminum ions in the brain cause serious problems such as alzheimer, parkinson and other degenerative diseases. on the other hand, zinc is a dietary element essential for several biological processes, modulates neurotransmission in brain regions and associates with ...
hormone-independent prostate cancer cell lines are resistant to antineoplastic drugs, this study sought to determine the usefulness of lithium chloride as an inhibitor of glycogen synthase kinase-3β to increase the cytotoxic effect of doxorubicin, etoposide or vinblastine antineoplastic drugs on du145 cells. combination effect was assessed by using low and ic50 doses of drugs + lithium chloride...
among the environmental stresses, salinity is a major limiting factor in world legumes production is considered. in this study, sodium chloride and salicylic acid interaction on growth parameters were investigated in greenhouse with factorial arrangement in randomized complete block design with three replications. the plant consisted of three cultivars of lentil (kimiya, kermanshah and gachsara...
