摘要
用不同剂量前列腺素E1(PGE1,100μg·kg-1体重、500μg·kg-1体重)注入急性梗阻性胆管炎(AOC)大鼠腹腔,设立盐水对照组,观察动物不同时间的死亡率,并检测血液内毒素、肿瘤坏死因子(TNF)浓度变化趋势。结果:大剂量PGE1组死亡率明显低于盐水对照组;各组血液内毒素变化无显著差别,均随时间延续呈上升趋势;3组TNF浓度呈上升后下降,治疗组趋势平缓,高峰推迟。证明大剂量PGE1对TNF有抑制作用,可降低AOC大鼠死亡率。
Rats with acute obstructive cholangitis(AOC) were injected different doses of prostaglandin E 1(PGE 1)(100μg/kg and 500μg/kg)intraperitoneally.Saline group was served as the control.The mortality rates at 6,12,18,24,48 and 72h were observed and the plasma endotoxin concentration and tumor necrosis factor(TNF) concentration were examined.The results revealed:the mortality of large dose group was significantey lower than saline group;endotoxin concentration in all groups increased persistently and there was no significant difference among these three groups;TNF concentration in each group increased first and then decreased,the changes in treatment groups were gentle and their peak values were postponed.It was demonstrated that large dose of PGE 1 could inhibit the action of TNF and decrease the mortality of AOC rats.
