【摘要】: 目的:研究常体、热体、寒体各组间在攻毒发热后下丘脑PGE-2、AVP、血清中IL-1β含量变化。揭示不同体质大鼠攻毒发热后中枢发热解热介质含量的变化与体质的相关性。 方法:参照文献造模方法,经过预实验改良饲养方法,复制常体、热体、寒体大鼠模型。喂养大鼠四周后,每天固定时间测量大鼠肛温,连续3天。常体组为均值±0.2℃,热体或寒体组为均值±1℃,两组体温相差在2℃以上,证明造模成功。用大肠杆菌内毒素攻毒法复制大鼠发热模型,采用放射免疫法测定大鼠攻毒发热后下丘脑PGE-2、AVP含量、血清中IL-1β的含量。 结果:常体、热体、寒体不同体质大鼠攻毒发热后体温波动有差别,寒体组对攻毒反应强烈,体温波动大,但反应时间相对滞后,热体组和常体组体温波动相对较小。发热介质IL-1β及PGE-2含量与ΔT变化曲线一致,1h IL-1β、PGE-2含量比较不同体质之间存在显著差异(p<0.05),3h常体组IL-1β、PGE-2含量大于寒体组(p<0.01)、大于热体组(P<0.05),6h寒体组IL-1β含量小于热体组(p<0.05),寒体组PGE-2含量小于常体组(p<0.01)。 负反馈因素AVP与体温曲线呈反向变化,3hAVP热体组小于寒体组(p<0.05),热体组大于常体组(P<0.01),6h AVP寒体组大于热体组(P<0.05)。 结论:体质的差异决定了攻毒发热后,中枢发热和解热介质含量的差异性。
[Abstract]:Objective: to study the hypothalamic PGE-2 AVP in the hypothalamus after the attack of toxin and fever among the groups of normal body, hot body and cold body. The change of IL-1 尾 content in serum revealed the correlation between the changes of central fever and antipyretic medium in rats with different physical constitution. Methods: according to the method of model making in literature, the rat model of normal body, hot body and cold body was established by preexperiment and improved feeding method. After feeding rats for four weeks, the anus temperature of rats was measured at a fixed time every day. For 3 consecutive days, the mean value of normal body group was 卤0.2 鈩,
