益气活血补肾法对早期糖尿病肾病血管活性物质的影响

观察益气活血补肾法（治糖保肾冲剂）对早期糖尿病肾病（DN）血管活性物质的影响。将63例DN患者随机分为中药组（治糖保肾冲剂）32例,西药组（洛丁新）31例,疗程3个月。结果：两组治疗后尿微量白蛋白排泄率（UAER）均明显下降（P＜0．01）,血浆内皮素（ET－1）亦明显下降（P＜0．05）,组间比较P＞0．05;中药组治疗后血浆一氧化氮（NO）水平明显下降（P＜0．05）,西药组NO水平下降,但无显著差异,P＞0．05,组间比较P＜0．05,提示益气活血能的治糖保肾冲剂治疗早期DN的机理与调整ET－1,NO水平有关。     

Evaluation on Antisperm Antibody of Infertile Men with Absolute Immotile Sperm

Objective To investigate the level of antisperm antibodies(ASA) in infertile men with absolute immotile sperm(AIS).Methods Thirteen men with AIS were enrolled into this study. Sperm immotility of ejaculates from these infertile men was proven by two or three consecutive semen analyses. Sperm vitality was assessed by the eosin exclusion. Serum and seminal plasma were screened by the indirect immunobead test(IBT) for ASA type IgG and IgA according to the WHO laboratory manual.Results Semen samples from these patients showed ejaculate volume, pH, and sperm count in the normal range. Sperm vitality, sperm concentration, and sperm abnormal forms in these cases were 40.2 ± 11.1%, 45.0 ± 11.9 × 106/ml, and 97.8 ± 1.4%,respectively. No case had the positive or sub-positive level of ASA type IgG and IgA in samples of both serum and seminal plasma.Conclusion ASA is not associated with the pathogenesis of AIS-associated infertility.
