introduction: prenatal stress has deleterious effects on the development of the brain and is associated with behavioral and psychosocial problems in childhood and adulthood. this study aimed to determine the protective effect of l-arginine on fetal brain under maternal stress. methods: twenty pregnant wistar rats (weighting 200-230 g) were randomly divided into 4 groups (n=5 for each group). th...
Background: Role of nitric oxide (NO) in morphine-induced conditioned place preference (CPP) has already been proposed in the rat medial septum (MS), but no molecular evidence has been provided to clear this fact. Methods: Effects of intraseptal injections of L-arginine and/or NG-nitro-L-arginine methyl ester (L-NAME) on morphine place conditioning in Wistar rats were examined. Morphine (2.5-7....
Introduction: The role of ovarian hormones and nitric oxide (NO) on oxidative damage in brain tissues as well as learning and memory has been widely investigated.The present study was carried out to evaluate the effect of the precursor of NO, L-Arginine on learning and brain damage due to oxidative stress in ovariectomized (OVX) rats.Methods: Thirty -two rats were divided into four groups: 1) S...
context the occurrence of intradialytic hypotension (idh) during hemodialysis (hd) continues to be a main problem in patients with esrd (end-stage kidney disease). it also negatively affects health-related quality of life. we aimed to determine vasopressin effect in decreasing idh. evidence acquisition we reviewed clinical and experimental literature in a variety of sources, including pubmed, c...
Background and Objective: L - Arginine is a semi-essential amino acid that affects some blood indices. The purpose of this study was to evaluate the effect of supplementation of L - Arginine on plasma lipids, blood sugar and blood pressure in healthy subjects. Materials and Methods: This study was a randomized double-blind controlled clinical trial. A lot of, 56 male athletes wit...
This experiment was conducted to investigate effects of l-arginine on productive performance and egg quality parameters, blood and hormone parameters of laying hens in late phase of production for 8 weeks. Forty eight Hy-Line W-36 were used in a completely randomize design with four level of l-arginine (1/20=control diet, 1/32, 1/44 and 1/56 percent) and four replicate from 92-98 weeks of age. ...
The objective of the present study was to determine the best dietary level of L-arginine on the growth performance, carcass traits, and blood parameters of female Ross broiler chickens in the starter and grower periods. In this experiment, 192 day old female Ross broiler chicks were fed with 4 dietary treatments in a completely randomized design, in which each dietary treatment included 4 repli...
Objective: Hypertension is a common component of metabolic syndrome (MetS). Some studies showed that L-arginine reduced the blood pressure (BP) .Therefore this study was designed to evaluate the effect of L-arginine supplementation on BP in MetS. Materials and Methods: In this randomized, double-blind, placebo-controlled trials, 60 patients with MetS were randomly divided into two groups: the ...
سابقه و هدف: تاکنون مطالعات اندکی بر روی کشت قلب جنین موش در شرایط in vitro صورت گرفته است. هدف این تحقیق تعیین مدت زمان امکان نگهداری قلب فعال در محیط کشت و مقایسه میزان رشد و نمو آن تحت شرایط in vitroبا in vivo و تاثیر میدان الکترومغناطیسی وL-Arginine در رشد و نمو قلب و تمایز آن می باشد.روش بررسی: در این مطالعه تجربی، قلب جنین موش های 11 روزه با استفاده از استریومیکروسکوپ جدا شده و به محیط کش...
Introduction: The current study aimed at investigating the role of Nitric Oxide (NO) in the maintenance of anxiety and depression induced by stress in male Wistar rats using intra-Basolateral Amygdala (BLA) injection of NO precursor, L-arginine, Nitric Oxide Synthase (NOS) inhibitor, and L-NAME. Methods: Two 23-gauge stainless steel cannulas were placed in the BLA, stereotaxically. Seven days...
