Abstract
- Contractility, in vitro, was examined in uterine horns of rats acclimated to 35 degrees C and controls (22 degrees C). 2. Responses to oxytocin and prostaglandin F2 alpha were measured in the four stages of the estrus cycle and on day 4 of pregnancy. 3. Responses to oxytocin of uteri from heat acclimated rats were significantly depressed in estrus, metestrus and diestrus, while responses to prostaglandin F2 alpha were decreased in estrus and metestrus. 4. Responses to oxytocin and prostaglandin were slightly but insignificantly decreased in uteri from pregnant day 4 heat-acclimated rats.
摘要
- 在适应35摄氏度的大鼠子宫角和对照组（22摄氏度）中检测体外收缩性。2. 在发情周期的四个阶段以及妊娠第4天测量对催产素和前列腺素F2α的反应。3. 热适应大鼠子宫对催产素的反应在发情期、间情期和动情后期显著降低，而对前列腺素F2α的反应在发情期和间情期降低。4. 妊娠第4天热适应大鼠子宫对催产素和前列腺素的反应略有降低，但无统计学意义。
