این پژوهش به منظور بررسی تاثیر هورمون گنادوتروپین انسانی و عصاره هیپوفیز کپور بر میزان پاسخ مولدین به القای هورمونی، هماوری کاری (تعداد تخمک استحصال شده)، شاخص های لقاح (درصد لقاح، چشم زدگی و تخم گشایی) در ماهی سوف معمولی sander lucioperca (l.) و کیفیت اسپرماتوزوآ ( تراکم، مدت زمان تحرک، درصد تحرک اسپرماتوزوآ و درصد اسپرماتوکریت) در مولدین نر صورت گرفت. علاوه بر این تاثیر استفاده از هورمون گناد...
تحقیق حاضر در راستای دستیابی به اهداف: الف) بازیافت ضایعات ذرت از طریق تبدیل آن به ورمی کمپوست، ب) بهبود کیفیت ورمی کمپوست از طریق تغییر نوع بستر و هم چنین ج) افزودن لجن فعال فاضلاب به عنوان منبعی از باکتری های تثبیت کننده نیتروژن و باکتری های محلول کننده فسفر و تغییر زمان تلقیح آن و کاهش دوره کمپوست سازی انجام پذیرفت. در این تحقیق، چهار غلظت لجن فعال فاضلاب (شامل 0، 2000، 4000 و mg/l 6000) در ...
PURPOSE The effect of clinical L-3,4-dihydroxyphenylalanine (L-DOPA) doses on the binding of [121I]N-Ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl)nortropane (121[I]FP-CIT) to the rat dopamine transporter (DAT) was investigated using small animal single-photon emission computed tomography. MATERIALS AND METHODS DAT binding was measured at baseline, after challenge with the aromatic L-amino ...
Copper pollution in soils is widespread, and its accumulation in crop products could pose a risk on human health. In this paper, bioavailability of added copper (Cu) and critical Cu concentrations in a vegetable garden soil was evaluated for Chinese cabbage (Brassica chinensis L.), pakchoi (Brassica chinensis L.), and celery (Apiumg graveolens L. var. dulce DC) based on human dietary toxicity. ...
BACKGROUND/AIMS This study was performed in order to elucidate the effects of 7-nitroindazole (7-NI) and L-arginine on cognitive functions of rats in a three-panel runway task. METHODS 7-NI (2.5, 5, 10 mg/kg) and L-arginine (200 mg/kg) were injected intraperitoneally into male Wistar rats 30 min before the test. RESULTS 7-NI (5, 10 mg/kg) significantly increased the number of errors (pushes...
We focused on the therapeutic effect of the stable gastric pentadecapeptide BPC 157 and how its action is related to nitric oxide (NO) in persistent colocutaneous fistula in rats (at 5 cm from anus, colon defect of 5 mm, skin defect of 5 mm); this peptide has been shown to be safe in clinical trials for inflammatory bowel disease (PL14736) and safe for intestinal anstomosis therapy. BPC 157 (10...
The aim of the present study was to investigate the possibility that catecholaminergic pathways within the central nervous system play a role in the control of renin secretion. Plasma renin activity (PRA) was measured after intravenous administration of L-dopa with and without prior inhibition of extracerebral dopa decarboxylase by carbidopa (MK-486) in pentobarbital-anesthetized dogs in which ...
the methanolic extract of leaves of turnera ulmifolia l was evaluated for its effect on blood glucose in alloxan-induced diabetic and euglycemic rats. the extract were administered at three doses of 100, 200 and 400 mg/kg, p.o. glibenclamide (10 mg/kg, p.o.) was used as standard for control group. in euglycemic rat, extract were administered at three doses of 100, 200 and 400 mg/kg, p.o. extrac...
BACKGROUND Cyclooxygenase-2 selective inhibitors have been developed to alleviate pain and inflammation; however, the use of a selective cyclooxygenase-2 inhibitor is associated with mild edema, hypertension, and cardiovascular risk. AIM To evaluate, in an experimental model in normotensive rats, the effect of treatment with parecoxib in comparison with diclofenac and aspirin and L-NAME, a no...
The influence of calcium channel antagonists on the behavioral sensitization to nicotine-induced hyperlocomotion and place preference was investigated. Locomotor sensitization in mice was produced by injecting nicotine (0.5 mg/kg, i.p.) for 5 consecutive days before placement in an apparatus in which locomotor activity was evaluated for 1 h. One week later, activity of mice was recorded after c...
