Introduction: The aim of the study was to evaluate the involvement of nitricergic system within the shell part of the nucleus accumbens (NAc) by injection of L-arginine, a nitric oxide precursor, and L NAME, a nitric oxide synthase inhibitor in the metabolic disturbances induced by acute stress in the male rat. Materials and Methods: Male Wistar rats were cannulated unilaterally in the left par...
اثر تجویز توأم مورفین و ال- آرﮊینین در ناحیه CA3 هیپوکامپ بر یادگیری و حافظه فضایی موشهای صحرایی نر
Background: Learning and memory are the complicated agents of central nervous system that various regions of brain can be involved in these phenomena, especially regions like hippocamp. Various agents like nitric oxide and morphine can influence learning and memory. About the effects of morphine with other components there was not clear reports so in this study the effect of co-administrati...
background: parkinson’s disease (pd) is a common neurodegenerative disease resulting from the degeneration of dopaminergic (da) neurons in the substantia nigra pars compacta (snc). increasing evidence demonstrated that mice treated intranasally with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (mptp) suffered impairments in motor functions associated with disruption of da neurons in snc conceiv...
introduction: this study was conducted to determine the possible beneficial results of l-arginine on prefrontal cortex of rats which impressed by immobilization stress to define the synchronous impression of stress and nitric oxide (no) on evolution of prefrontal cortex of rats after birth. methods: forty-eight one month, male wistar rats were divided into two groups: stressed and non-stressed....
The role of glutamate receptors within the nucleus accumbens in morphine tolerance has been postulated. Previous studies have reported that glutamate receptors exert their effects in part through the release of nitric oxide (NO). In the present study, the effect of intra-accumbal injections of L-arginine, the NO precursor and L-NAME, the NOS inhibitor on the morphine tolerance in Wistar rats (2...
Introduction: Previous studies shows L-arginin (nitric oxide precursor) increases conditioned place preference and drug seeking behaviors whereas LG-nitro-arginine methyl ester) L-NAME( as nitric oxide synthase inhibitor decreases this process. In this project, effects of intra-central amygdale bilateral injection of nitric oxide agents on drug-seeking behaviors including rearing, sniffing and ...
In the past few years Meldrum's acid furfural conjugate (MAFC) have been extensively explored as starting material for synthesis of photo switchable donor acceptor stenhouse adducts (DASA). Hereby, we interaction MAFC with various amino acids. To our surprise, nitrogen rich acids like lysine and arginine interact spontaneously to give colored adduct immediately, whereas other acids, including h...
the objective of the present study was to investigate the effects of high dietary levels of l-arginine during starter period on growth, intestine morphology and immune system of female ross broiler chicks. 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 replications. dieta...
background: identifying new ways to decrease adiposity will be very valuable for health. the aim of this study was to find out whether l-arginine (arg) and selenium alone or together can increase the effect of hypocaloric diet enriched in legumes (hdel) on anthropometric measures in healthy obese women. methods: this randomized, double-blind, placebo-controlled trial was undertaken in 84 health...
background: role of nitric oxide (no) on expression of morphine conditioning using a solely classic task has been proposed previously. in this work, the involvement of no on the expression of opioid-induced conditioning in the task paired with an injection of naloxone was investigated. methods: conditioning was established in adult male wistar rats (weighing 200-250 g) using an unbiased procedu...
