Previously, we demonstrated intrathecal administration of oxytocin strongly induced anti-hyperalgesia in male rats. By using an oxytocin-receptor antagonist (atosiban), the descending oxytocinergic pathway was found to regulate inflammatory hyperalgesia in our previous study using male rats. The activity of this neural pathway is elevated during hyperalgesia, but whether this effect differs in ...
Background and purpose: Chronic stress has detrimental effects on reproductive system. Offspring are likely to be vulnerable to adverse effects from antipsychotic medication and stress transmitted through gonads and gametes. The present study aimed to investigate the fertility of female rats from male rats treated with sulpiride because of chronic physical or psychological stress. Materials a...
Maternal separation (MatSep) is a model of behavioral stress during early life. We reported that MatSep exacerbates ANG II-induced hypertension in adult male rats. The aims of this study were to determine whether exposure to MatSep in female rats sensitizes blood pressure to ANG II infusion similar to male MatSep rats and to elucidate renal mechanisms involved in the response in MatSep rats. Wi...
Background: Opposite observations about the discrepancy in the pain perception between male and female has been reported. In this regard, in this research pain thresholds among male and female rats in different phases of oestrous cycle were evaluated via tail immersion test. In addition, the efficiency of alcoholic seed extract of Datura stramonium in the modulation of acute pain threshold ha...
objective: melanocortin-4 receptor (mc4r) and agouti-related peptide (agrp) are involved in energy homeostasis in the rat. the aim of the present study was to evaluate the expression of mc4r and agrp mrnas in arcuate nucleus (arc) during long term malnutrition of female ovariectomized rats. materials and methods: ten female ovariectomized rats were divided into two equal groups (n=6) of normal ...
Abstract Background: Chlorpromazine has been widely used to treat schizophrenia there are some reports about negative side effects of phenothiazines on the reproductive system. The present study was undertaken to consider the effects of the Chlorpromazine on the reproductive functions in female rats. Materials and methods: This experimental study was conducted on 32 adult female wistar rats div...
the aim of this study was to investigate the effect of acute swimming stress on plasma corticosterone and leptin levels in female and male rats. thirty- seven adult male (n=20) and female (n=20) sprague dawley rats (200-250 g weight) were used. the leptin and corticosterone levels were measured following swimming stress (10 minutes) or no stress. plasma leptin and corticosterone were measured b...
Eckel, Lisa A., Heidi M. Rivera, and Deann P. D. Atchley. The anorectic effect of fenfluramine is influenced by sex and stage of the estrous cycle in rats. Am J Physiol Regul Integr Comp Physiol 288: R1486 –R1491, 2005. First published January 6, 2005; doi:10.1152/ajpregu.00779.2004.—The controls of food intake differ in male and female rats. Daily food intake is typically greater in male rats,...
Aging is a critical risk factor for Parkinson's disease. Silibinin, a major flavonoid in Silybum marianum, has been suggested to display neuroprotective properties against various neurodegenerative diseases. In the present study, we observed that neonatal iron (120 μg/g body weight) supplementation resulted in significant abnormality of behavior and depletion of striatal dopamine (DA) in the ag...
