【摘要】： 目的:研究常體、熱體、寒體各組間在攻毒發(fā)熱后下丘腦PGE-2、AVP、血清中IL-1β含量變化。揭示不同體質大鼠攻毒發(fā)熱后中樞發(fā)熱解熱介質含量的變化與體質的相關性。 方法:參照文獻造模方法,經過預實驗改良飼養(yǎng)方法,復制常體、熱體、寒體大鼠模型。喂養(yǎng)大鼠四周后,每天固定時間測量大鼠肛溫,連續(xù)3天。常體組為均值±0.2℃,熱體或寒體組為均值±1℃,兩組體溫相差在2℃以上,證明造模成功。用大腸桿菌內毒素攻毒法復制大鼠發(fā)熱模型,采用放射免疫法測定大鼠攻毒發(fā)熱后下丘腦PGE-2、AVP含量、血清中IL-1β的含量。 結果:常體、熱體、寒體不同體質大鼠攻毒發(fā)熱后體溫波動有差別,寒體組對攻毒反應強烈,體溫波動大,但反應時間相對滯后,熱體組和常體組體溫波動相對較小。發(fā)熱介質IL-1β及PGE-2含量與ΔT變化曲線一致,1h IL-1β、PGE-2含量比較不同體質之間存在顯著差異(p＜0.05),3h常體組IL-1β、PGE-2含量大于寒體組(p＜0.01)、大于熱體組(P＜0.05),6h寒體組IL-1β含量小于熱體組(p＜0.05),寒體組PGE-2含量小于常體組(p＜0.01)。 負反饋因素AVP與體溫曲線呈反向變化,3hAVP熱體組小于寒體組(p＜0.05),熱體組大于常體組(P＜0.01),6h AVP寒體組大于熱體組(P＜0.05)。 結論:體質的差異決定了攻毒發(fā)熱后,中樞發(fā)熱和解熱介質含量的差異性。
[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 鹵0.2 鈩，
