摘要
目的：探讨维生素Ｅ（ＶＥ）对大白鼠寒冷的保护作用。方法：采用放射免疫分析法测定不同低温下大白鼠补充ＶＥ后血浆中环核苷酸含量，经方差分析和ｑ检验。结果：单纯冷暴露组大白鼠血浆中环核苷酸含量随温度下降而持续增高，冷暴露同时饲喂ＶＥ组，大白鼠血浆中ＣＡＭＰ含量与室温对照组差异无显著性（Ｐ＞０．０５）。结论：ＶＥ可通过影响冷暴露大白鼠体内环核苷酸代谢，以促进机体对寒冷的适应，提高机体的耐寒力。
Objective:To discuss the mechanism of Vitamin E on enhancement of anti cold ability in rats.Methods:Supplied the rats with vitamin E,and then measured the plasma contents of cyclic nucleotide in at different low temperatures with radioimmunoassay.The data were analyed with variance and Q test.Results:The plasma content of cAMP in rats without Vitamin E supply increased continuously with the diciease in body temperature after exposing to cold.The change in plasma content of cAMP were not significant between the rats supply with Vitemin E and exposing to cold and the control rat kept in room temperature with vitamin E supply.Conclusions:Vitamin E can enhance the adaptability of rats in cold weather and increase its' anti cold ability by influencing the metabolism of cAMP.
