Tourniquet application is a widely accepted adjuvant technique in extremity surgery. The purpose of this prospective, randomized trial was to evaluate the effect of cuff width on skeletal muscle ischemia-reperfusion injury. A 2- or 4-cm wide curved tourniquet cuff was applied around the midthigh of 36 New Zealand White rabbits and inflated to a pressure of 200 or 400 mm Hg for 2 hours: group A=...
در این تحقیق، میزان حذف تری بوتیل فسفات (tbp) از محلولهای آبی بوسیله فرایند فتوکاتالیست مورد بررسی قرار گرفت. عوامل موثر در فرایند شامل غلظت آلاینده، غلظت فتوکاتالیست تیتانیا، غلظت پراکسید هیدروژن، استفاده از لامپ های uv-c و uv-aو حضور نمکهای معدنی بررسی شدند. نتایج آزمایش که به کمک gc آنالیز شد، نشان داد که پرتو uv به تنهایی بعد از گذشت 120 دقیقه درصد قابل قبولی از این ماده را حذف نمود. تاثیر ...
The possible protective effects of NMDA receptor antagonists dizocilpine (MK-801) and D(-)-2-amino-5-phosphonopentanoic acid (AP5), and nitric oxide synthase (NOS) inhibitors L-nitro-arginine methyl ester (L-NAME) and 7-nitro-indazol (7-NI) on the methylmercury (MeHg)-induced dopamine (DA) release from rat striatum were investigated using in vivo microdialysis. Intrastriatal infusion of 400 mic...
The uteri, spontaneously active or Ca(2+) (6 mM) induced, were allowed to equilibrate, and to inhibit voltage-gated potassium (K(V)) channels 1 mM 4-amino pyridine (4-AP) was applied for 15 min before adding H(2)O(2). H(2)O(2) was added cumulatively: 2 μM, 20 μM, 200 μM, 400 μM, and 3 mM. Average time for H(2)O(2) concentrations (2, 20, 200, and 400) μM to reach its full effect was 15 min. H(2)...
To evaluate the capacity of different metabolic indices to predict performance in middle distance swimming, 15 competitive swimmers performed a submaximal and a maximal 400 metres freestyle swimming event. Expired gases were collected in Douglas bags immediately after the events for the determination of VO2 max. Arterialized blood samples were collected for the determination of maximal blood la...
The aim of this study was to improve the quantitative and qualitative characteristics and vase life of rose (Rosa hybrida cv. Dolcvita). For this purpose, an experiment was conducted in a randomized complete design with 7 treatments and 4 replications in a commercial rose-growing greenhouse, equipped with soilless culture, adjacent to Yasouj city, Iran. Treatments included: Control, 200 and 400...
In the present study, the effects of intrastriatal administration of different concentrations (40 microM, 400 microM, and 4 mM) of inorganic mercury (HgCl(2)) on the dopaminergic system of rat striatum were evaluated, using a microdialysis technique coupled to liquid chromatography-electrochemical detection. In previous studies, we discussed the effects of organic mercury (MeHg) administration ...
