前列舒通片对大鼠非细菌性前列腺炎炎症反应的抑制作用

目的：观察前列舒通片（QLS）对非细菌性急、慢性前列腺炎模型中炎症反应的作用，为临床应用提供药效学依据。方法：Wistar大鼠按体重区组随机分组方法分为空白对照组、模型组、阳性对照组(前列康片组)及QLS低（17.5 mg•kg^-1）、中（35.0 mg•kg^-1）、高剂量组（70.0 mg•kg^-1），每组10只，分别于前列腺背叶的精囊腺注入1 %角叉菜胶生理盐水溶液，制作大鼠非细菌性前列腺炎模型，观察测定前列腺液中白细胞数和卵磷脂小体密度、前列腺重量、前列腺指数。在大鼠前列腺内注入消痔灵注射液制作非细菌性慢性前列腺炎模型，给药30 d后处死，观察前列腺组织形态学变化。结果：与模型组比较，QLS各给药组白细胞数不同程度减少。35.0和70.0 mg•kg^-1 QLS组前列腺液中白细胞数明显减少（P<0.05），卵磷脂小体密度显著增加（P<0.05或P<0.01）；17.5 mg•kg^-1 QLS组前列腺液中白细胞数减少、卵磷脂小体密度增加不明显。与模型组比较，70.0 mg•kg^-1 QLS组前列腺重量和前列腺指数明显减小、白细胞的浸润和纤维母细胞的增生减轻（P<0.05或P<0.01）；35.0 mg•kg^-1 QLS组前列腺指数明显降低（P<0.05），白细胞浸润减轻（P<0.01）。结论：QLS具有抑制大鼠非细菌性急、慢性前列腺炎炎症反应的作用。  

Effects of Qianlie Shutong Tablets on inflammatory reaction of nonbacterial prostatitis in rats

Objective To investigate the effects of Qianlie Shutong Tablets(QLS) on inflammatory reaction of nonbacterial acute and chronic prostatitis in rats and provide medical basis for its clinical use. Methods A total of 60 male rats were randomly assigned into normal group,model group,drug control group (Qianliekang group),low -dose(17.5 mg·kg-1),mid-dose (35.0 mg·kg-1) and high -dose QLS (70.0 mg·kg-1) groups,10 rats in each group. White cell count,lecithin corpuscle density in prostatic fluid,prostate weight and prostate index were observed respectively after acute rat models were made by injecting 1 % carrageenan in the seminal vesicle of prostate gland notopodium. The chronic prostatitis models were made by injecting hemorrhoid into prostate gland. The morphological changes of prostate tissue were observed 30 d after administration. Results Compared with model group,white cells in prostate fluid were obviously decreased (P<0.05) and lecithin corpuscle densities were obviously increased (P<0.05 or P<0.01) in 35.0 and 70.0 mg·kg-1 QLS groups. However,QLS with the dose of 17.5 mg·kg-1 did not obviously affect the number of white cells and lecithin corpuscle density. Compared with model group,QLS with the dose of 70.0 mg·kg-1 significantly diminished prostate weight(P<0.05)and prostate index(P<0.01),as well as significantly inhibited infiltration of white cells(P<0.01)and fibroblast accrementition (P<0.05),which was similar with the positive Qianliekang group. QLS with the dose of 35.0 mg·kg-1 significantly diminished prostate index(P<0.05) and inhibited infiltration of white cells(P<0.01). Conclusion QLS has inhibitory effects on inflammatory reaction of nonbacterial acute and chronic prostatitis.
