Abstract

Introduction: Stress is one of the most important parameters that causes changes in circadin cycle. Recent investigation showed that prenatal - stress (PS) causes depression and anxiety in man. In this study the effect of PS on sleep - wakefulness was evaluated in rat.Methods: The male and female rats were mated and after 24 hours pregnant rats were divided into two groups: control group which spent the period of pregnancy in the normal laboratory conditions and the other one as the experimental group was subjected to immobilization stress in the restrainer from day 14th of pregnancy between 9 to 11 a.m every day for one week 24 hours after final injection the sleeping time was measured by physiograph. Two subgroups (intact and PS) which received 200mg testosterone were selected for electrophysiological experiments. Statistically analysis was one way ANOVA.Results: The results of this study indicated that prenatal stress significantly deceased sleeping time in male rats, P<0.05 which is reversed by injection of testosterone. Electrophysiological studies of sleep also was begun 24 hours after behavioural observation. - These studies showed that prentatal immobilization stress increased alpha and teta rhythms and decreased delta rhythm of brian waves. Injection of testosterone in both control and PS groups incerased delta rhythm and decreased teta rhythm noticeably and also increased total power of brain waves.Discussion: As a results, testosterone increased total sleep and decreased insomnia which is induced by prenatal immobilization stress. It seems that these changes in total .sleeping time relative to changes in neurotransmitter and hormons in CNS.
