摘要: 目的 观察萘哌地尔衍生物BWYJ 对前列腺增生模型的作用。方法 采用激素法建立去势大鼠和未去势小鼠前列腺增生模型, 通过小鼠前列腺湿重, 计算前列腺指数。光镜及透射电镜下, 分别观察小鼠前列腺组织形态学及超微结构变化;TUNEL 法检测BWYJ对大鼠前列腺细胞凋亡的影响。结果 BWYJ 5 、10 、20 mg·kg-1组均可降低BPH 小鼠前列腺湿重指数(P<0.05) , 光镜及电镜结果表明, BWYJ5 、10 、20 mg·kg-1组均可抑制小鼠组织结构增生性变化, 且BWYJ 10 、20 mg·kg-1组使腺腔直径、腺体表面积变小(P<0.05) 。TUNEL 检测发现, 大鼠前列腺凋亡细胞检出率较低, 与模型组比较, BWYJ 各剂量组差异无统计学意义(P>0.05) 。结论 BWYJ 具有抗小鼠及大鼠良性前列腺增生作用。

Abstract: AIM: To observe the effect of naftopidilderivant BWYJ on benign prostatic hyperplasia (BPH) induced by testosterone propionate in castrated rats and uncastrated mice.METHODS: Castrated rats and uncastrated mice were injected subcutaneously testosterone propionate to induce BPH.The effect of BWYJ on mice with BPH was obtained by the prostatic wet weight and wet weight index.As well morphological changes of prostate were observed through light microscope and electron microscope,and were semi-quantified by image analysis system.The apoptotsis of prostatic cells in rat was detected by TUNEL assay.RESULTS: BWYJ decreased the prostate wet weight index (P<0.05).BWYJ inhibited histomorphological changes of BPH induced by testosterone propionate in uncastrated mice.Few apoptosis cell was detected by TUNEL assay in BWYJ-treated groups compared with model grouP(P>0.05).CONCLUSION: BWYJ inhibits BPH induced by testosterone propionate in KM mice and SD rat.
