柴胡注射液对家兔内生致热原性发热及其脑脊液cAMP含量变化的效应

Effect of Bupleurum Chinense injection on endogenous pyrogen fever and change of cAMP concentration in cerebrospinal fluid in rabbits

本实验共分二部分进行。第一部分,观察柴胡注射液解热效应,第二部分,观察柴胡注射液解热时对脑脊液cAMP含量变化的影响。用家兔内生致热原复制发热模型,剂量(1×10~6 cells/ml)0.5ml/kg。目前认为:cAMP是一种重要的中枢性发热介质,脑脊液中cAMP含量与发热效应呈正相关。本研究结果表明,柴胡注射液(250mg/kg)对内生致热原性发热有明显抑制作用;同时,脑脊液中cAMP含量也明显低于发热对照组。作者推论:柴胡注射液可能通过某些环节减少体温调节中枢神经元cAMP合成和释放,从而抑制发热效应。

The experiments were divided into two parts. The first part: inhibitory effect of Bupleurum Chinense injection on fever was observed. The second part: while Bupleurum Chinense injection inhibited fever, the cAMP concentration in cerebrospinal fluid was observed. The experimental fever models were induced by endogenous pyrogen from monocytes of rabbits' blood. The results obtained demonstrated that the Bupleurum Chinense injection (250mg/kg) had marked inhibitory effect on the endogenous pyrogen fever and the cerebrospinal fluid cAMP levels of the experimental group was obviously lower than in control. The authors inferred that inhibitory effect of Bupleurum Chinense injection on endogenous pyrogen fever may be obtained through some-link to reduced central cAMP content.
