补骨脂与鸦胆子对感染卡氏肺孢子虫大鼠IL-2水平和NK细胞活性的影响

中药补骨脂（10.0 mg/kg）、鸦胆子（1.2 mg/kg）及两药合剂（补骨脂5.0 mg/kg，鸦胆子0.6 mg/kg）治疗PCP卡氏肺孢子虫肺炎（PCP）大鼠。通过检测脾NK细胞活性和血清IL-2水平，探讨两药对PCP大鼠的免疫调节作用。结果表明，与PCP模型对照组比较，补骨脂治疗组血清IL?鄄2诱生水平（526.1±5.5） pg/ml和脾NK细胞活性（27.1%±0.8%）均显著升高（P<0.01），两药合剂组其次［（314.7±6.7) pg/ml， (22.9%±0.9%）（P<0.05）］，鸦胆子组较低［（285.4±6.1） pg/ml， （20.7%±1.0%） （P<0.05）］。补骨脂和鸦胆子具有增强PCP大鼠免疫调节的作用。

Effects of Fructus psoraleae and Brucea javanica on the Level ofIL-2 and NK cell in Rats Infected with Pneumocystis carinii

SD rat model of PCP was established by subcutaneous injection with dexamethasone. The treatment groups received Fructus psoraleae (FP, 10.0 mg/kg), Brucea javanica (BJ, 1.2 mg/kg) and a mixture of the two Chinese herbs(FP 5mg/kg, BJ 0.6 mg/kg) respectively. By means of detecting the level of IL-2 in sera and NK cells in spleens, the effect of FP and BJ on the level of IL-2 and NK cells in rats with Pneumocystis carinii pneumonia (PCP) was observed, with SMZco treatment group (TMP 50 mg/kg, SMZ 250 mg/kg) and groups of infected and normal rats as controls. Compared with the infected group, the level of IL-2(526.1 +/- 5.5) pg/ml and NK cells (27.1% +/- 0.8%) significantly increased in the FP group (P < 0.01), followed by the FP/BJ combination group (314.7 +/- 6.7) pg/ml, 22.9% +/- 0.9%) (P < 0.05)], and BJ group (285.4 +/- 6.1) pg/ml, 20.7% +/- l.0%) (P < 0.05)]. Chinese herbs Fructus psoraleae and Brucea javanica show an immune regulatory action on the PCP rats.
