摘要
目的:研究精浆抗精子抗体(AsAb)阳性对精子顶体酶、精浆一氧化氮合酶(NOS)及超氧化物歧化酶(SOD)活力的影响。方法:精浆AsAb阳性不育者40例,对照组为40例正常生育男性。通过吸光度变化分别计算顶体酶活力(BAEE/ADH联合法)、NOS活力(氧化还原反应)、SOD活力(黄嘌呤氧化酶法)。结果:精浆As-Ab阳性组与正常生育组比较,精子顶体酶活力明显降低(P<0.01),NOS活力明显升高(P<0.01),精浆中SOD活力明显降低(P<0.01)。结论:精浆AsAb阳性引起不育可能与精子顶体酶、精浆中SOD及NOS活力改变有关。
Objective: To study the impacts of positive antisperm antibody (AsAb) in seminal plasma on acrosomal enzyme activity, nitric oxide synthase(NOS) and superxide dismutase(SOD) levels of spermatozoa. Methods: Swatch from 40 infertile patients with positive AsAb in seminal plasma as experimental group, and 40 fertile men as control group. Acrosomal enzyme activity was detected by the BAEE/ADH unitive method, NOS was detected by the redoxreaction assay, and SOD level was measured xanthine oxidase method. Results: Compared with control group, acrosomal enzyme activity of spermatozoa of experimental group was significantly decreased (P 〈 0.01 ) , NOS activity was apparently increased (P 〈 0.01 ) , and SOD level in seminal plasma was markedly decreased ( P 〈 0.01 ). Conclusion : It may be possible that the positive AsAb in seminal plasma beget infertility through the changes of acrosomal enzyme of spermatozoa, SOD and NOS activitise in seminal plasma.
