大蒜素治疗大鼠卡氏肺孢子虫肺炎的研究

目的　研究大蒜素对大鼠卡氏肺孢子虫肺炎(PCP)的治疗效果。　方法　地塞米松连续肌肉注射Wistar大鼠8周,建立大鼠PCP动物模型。用大蒜素治疗实验大鼠,同时设复方新诺明治疗对照组和PCP模型空白对照组。通过各组大鼠肺重、肺重/体重比值、肺印片中每100个油镜视野肺孢子虫包囊均数等指标考核疗效。　结果　大蒜素治疗组大鼠平均肺重为1.73±0.17、肺重/体重比值为0.84±0.12,显著低于PCP模型对照组的 2.31±0.35、1.25±0.35(P<0.01)。肺印片中包虫数较PCP模型对照组减少62.9% ,其与复方新诺明治疗对照组接近。　结论　大蒜素对实验大鼠卡氏肺孢子虫肺炎有明显的治疗作用,治疗效果接近复方新诺明。

The Experimental Study of Garlicin in Treating Pneumocystis carinii Pneumonia in Rats

Objective To assess the therapeutic effect of garlicin on Pneumocystis carinii pneumonia (PCP) of immuosuppressed rats. Methods The Wistar rats were injected intramuscularly continually with dexamethasone for eight weeks to establish the rat model of PCP. The rats were treated with garlicin, meanwhile control groups without treatment and with SMZ-TMP treatment were established respectively in PCP model. The efficacy was evaluated based on the lung weight, lung /body weight ratio and mean cyst number per 100 fields in lung print smear. Results The mean lung weight of the rats in garlicin is 1.73±0.17, lung/body weight ratio is 0.84±0.12, they are obvious lower than 2.31±0.35 and 1.25±0.35 of control (P<0.01). The numbers of cysts in lung print smear is reduced 62.9% compared with control. The results is similar to that with SMZ-TMP. Conclusion Garlicin shows an obvious therapeutic effect on Pneumocystis carinii pneumonia in rats with an efficacy similar to that with SMZ-TMP.
