The merits of isotope dilution are validated with the determination of lead concentration in standard reference materials including plant samples and human hair by ICP-MS, and the results are in good agreement with the certified values.

为考证同位素稀释测量方法的优点，用ICP-MS测量了植物、人发标准参考物质中的铅同位素比值，进而用同位素稀释法测定其中的铅含量，实验测量值与标准物质的铅参考值十分吻合。

Based on pre-experiment foundation of the earlier period, 60 male patients among 45-65 year old were chosed as the clinical case according to the PADAM diagnosis standard, and were divided into 3 groups according to the block stochastic principle, the observation group (acupuncture combined with BUSEHN capsule), group 1, group 2 (takes orally BUSEHN capsule group), each group had 20 cases, and each group of patients was measured by the method of radio-immunity for the serum level of testosterone, luteinizing hormoha, follicle-stimulating hormone before and after the treatment.

在前期预实验的基础上，选择符合诊断标准的PADAM诊断标准的45-65岁男性患者临床病例60例，按照区组随机原则分为3组，观察组、对照组1、对照组2，每组各20例，采用放射免疫法分别测定各组患者治疗前后血清中血清睾酮、黄体生成素、卵泡刺激素的血清浓度的水平；通过三组及三组间治疗前后PADAM症状评分指数的对比研究，揭示针药结合的整体调节作用特色，探讨提高针灸疗效的新途径；总结出针刺对中老年雄激素缺乏综合征患者的内分泌的调节及针刺对睾丸的改善程度，探讨针药结合治疗本病的机制及针灸增效剂的应用前景，为今后进一步研究打下坚实基础。
