摘要
目的探究两种黄芪剂量补阳还五汤对海绵体神经损伤性大鼠勃起功能障碍的治疗效果。方法将32只SD大鼠随机平均分成假手术组、模型组、30 g组(模型+含黄芪30 g补阳还五汤)、120 g组(模型+黄芪120 g补阳还五汤);通过手术对SD大鼠海绵体神经进行钳夹(但不剪断)以造成海绵体神经损伤所致勃起功能障碍(erectile dysfunction,ED)大鼠模型;术后5 d采用不同剂量黄芪(分别设置黄芪30、120 g)的补阳还五汤灌胃干预,假手术组与模型组均予以等量生理盐水灌胃,每日1次,连续30 d。30 d后测定大鼠阴茎海绵体内压(intracavernous pressure,ICP),Masson染色技术观察海绵体组织平滑肌与胶原沉积含量,免疫应荧光技术和Western Blot检测各组神经型一氧化氮合酶(neuronal nitric oxide synthase,nNOS),神经丝蛋白轻链多肽(neurofilament light polypeptide,NF-L),生长相关蛋白43(growth associated protein 43,GAP-43)变化。结果与假手术组相比,模型组大鼠ICP明显降低(P<0.01),阴茎海绵体平滑肌面积/胶原面积减少(P<0.01),NF-L、nNOS、GAP43水平明显下降(P<0.01);与模型组相比,30 g组与120 g组大鼠ICP明显增高(P<0.01),阴茎海绵体平滑肌面积/胶原面积增高(P<0.01),nNOS、NF-L、GAP43水平明显增高(P<0.01),其中与30 g组相比,120 g组大鼠ICP明显增高(P<0.05),阴茎海绵体平滑肌面积/胶原面积增高(P<0.05),nNOS、NF-L、GAP43水平明显增高(P<0.01)。结论补阳还五汤可以明显改善大鼠勃起功能障碍,且《医林改错》原方所载的补阳还五汤治疗效果更优。
Objective To explore the therapeutic effects of two different doses of Buyang Huanwu decoction containing Astragalus on erectile dysfunction(ED)in rats with cavernous nerve injury.Methods Thirty-two Sprague-Dawley(SD)rats were randomly divided into four groups:sham operation model,30 g(model+Buyang Huanwu decoction containing 30 g Astragalus)and 120 g(model+Buyang Huanwu decoction containing 120 g Astragalus).The cavernous nerve of the rats was surgically clamped(but not cut)to establish the rat model of ED caused by cavernous nerve injury.Five days after the operation,a 30 g or 120 g dose of Astragalus was used for the gavage intervention of Buyang Huanwu decoction,or the same volume of normal saline(sham and model groups)was given,once a day for 30 consecutive days.After 30 days,the intracavernous pressure(ICP)of the rat corpus cavernosum was measured.Masson staining was used to observe the content of smooth muscle and collagen deposition in the spongy tissue.Fluorescence and western blotting were used to detect changes in neuronal nitric oxide synthase(nNOS),neurofilament light polypeptide(NF-L),growth associated protein 43(GAP-43)expression in each group.Results Compared with the sham group,the model group showed significantly decreased ICP(P<0.01),decreased area of penile smooth muscle/collagen(P<0.01),and significantly decreased levels of NF-L,nNOS and GAP43(P<0.01).Compared with the model group,the rats in the 30 g and 120 g Astragalus groups showed significantly increased ICP(P<0.01),increased area of penile smooth muscle/collagen(P<0.01),and significantly increased levels of nNOS,NF-L and GAP43(P<0.01).Compared with the 30 g group,the rats in the 120 g Astragalus group showed significantly increased ICP(P<0.05),increased area of penile smooth muscle/collagen(P<0.05),and significantly increased levels of nNOS,NF-L and GAP43(P<0.01).Conclusions Buyang Huanwu decoction containing Astragalus obviously improved ED in cavernous nerve injury model rats.The higher dose of Astragalus(120 g),which is used in the o
