摘要
本实验用白色家兔,在常温(20±1℃)和高温环境(40±1℃)时,分别记录动物的直肠温度,并分别从动物的小脑延髓池抽取脑脊液(C. S. F. ),从耳缘静脉采血,用蛋白结合法测脑脊液(C. S. F. )和血浆中(cAMP)含量。动物在常温(对照组)和高温环境(热应激组)的平均直肠温度相比较,两者有显著性差异。而动物在常温及热应激时C. S. F. 和血浆中cAMP含量其差异均不显著。表明热应激时体温虽有显著升高而不能引起C. S. F. 和血浆中cAMP含量的增加。说明既往实验发热时体温升高很可能是由于C. S. F. 中cAMP含量增加所致。
White rabbits were placed in insulated chambers in which temperature was maintained at 19-21℃ (control group) and 39-41℃ (heat stress group) . Rectal temperature was measured and recorded continuously, cAMP levels in the C.S.F. and plasma were determined with protein-binding method. Difference of temperature between these two groups showed statistical significance,but the difference of cAMP levels between the control and heat stress group showed no statistical significance. The authors inferred that the temperature rise seen in the former experiments[1~6]might be the result of increase of cAMP levels in the C.S.F.
