| 摘 要： | 目的:观察瓜蒌注射液对血管平滑肌细胞(SMC)增殖细胞核抗原(PCNA)表达的影响。方法:用免疫组织化学LSAB法检测培养的兔主动脉SMC中PCNA的表达,液闪法测定SMC氚-胸腺嘧啶核苷(3H]-TdR)掺入量,同时测定培养液中超氧化物歧化酶(SOD)、脂质过氧化物(LPO)、前列环素(PGI2)及环磷酸腺苷(cAMP)的含量。结果:瓜蒌注射液能增加SOD活性,降低LPO和升高PGI2、cAMP水平,抑制SMC的3H]-TdR掺入量和PCNA的表达(P均＜0.05,0.01)。结论:瓜蒌有抑制SMC增殖的作用。

| Abstract: | AIM: To observe the effect of thichosanthes injection on the expression of proliferating cell nuclear antigen (PCNA) of vascular smooth muscle cell (SMC). METHODS: The expression of PCNA of cultured rabbit aortic SMC was examined with LSAB immunohistochemical technique, and 3H]-thymidine( 3H]-TdR) incorporation data of SMC and the contents of superoxide dismutase (SOD), lipid peroxide (LPO), prostacyclin (PGI 2) and cyclic AMP (cAMP) in medium were simultaneously determined. RESULTS: Thichosanthes injection has an effects of increasing SOD activity, decreasing LPO, elevating PGI 2 and cAMP, reducing 3H]-TdR incorporation and expression of PCNA (all P< 0 05, P <0 01). CONCLUSION: Thichosanthes could inhibit SMC proliferation. |
