Effect of xylazine and yohimbine on the phasic pain during the estrous cycle in the rat
The aim of the present study was to investigate the effect of α2-adrenergic agonist (xylazine) andantagonist (yohimbine) on phasic pain during estrous cycle in female rats. Adult female rats weighing 180-220 g were kept under controlled temperature (21-24°C) and light/dark conditions (light on at 6:00 a.m. and light off at 6:00 p.m.). Animals were divided into four groups: 1) control group whic...
متن کاملHippocampal GABAA Receptor and Pain Sensitivity during Estrous Cycle in the Rat
Background: Estradiol and progesterone as well as hippocampal GABAA receptors are believed to play a role in the modulation of pain. The aim of present study was to investigate the effect of intrahippocampal injections of GABAA receptor agonist (muscimol) and GABAA receptor antagonist (picrotoxin) on pain sensitivity during estrous cycle. Methods: Pain sensitivity was evaluated in rats ...
متن کاملThe rat estrous cycle revisited: a quantitative and qualitative analysis
The rat has been elected as the main animal model in several studies involving reproduction. However, there are scarce and conflicting data related to its estrous cycle. It comprises phases characterized by different cell types in vaginal smears (proestrus, estrus, metestrus and diestrus). Nevertheless, this classification and the time span of each phase are controversial and may induce mislead...
متن کاملEstrous Cycle Synchronization In
E STRUS and ovulation in gilts have been successfully inhibited by daily injections of progesterone (Ulberg et al., 1951; Baker et al., 1954) and more recently by the inclusion of progestational compounds in the feed (Nellor, 1960; Dzuik and Baker, 1962). The successful use of orally active progestational agents to synchronize the estrous cycles of gilts without a subsequent reduction in fertil...
