人口服富硒酵母的药物动力学研究

用金膜电极微分阳极溶出伏安法测定人口服富硒酵母(SEY)后的血浆硒浓度,并用一室模型分析 SEY 在健康人体内的药物动力学参数:半衰期(t_(1/2))3.50 h,吸收速度常数(k_a)0.57h^(-1),消除速度常数(k)0.20h^(-1),药物达峰时间(T_(max))3.39 h,血药浓度-时间曲线下面积(AUC_(0→∞))600 ng/(ml·h)。实验结果显示健康人口服 SEY 10 μgSe/kg 后12 h 从体内基本消除,24 h 后体内完全消除,故在低硒地区按推荐剂量补硒不易引起蓄积中毒。

RESEARCH INTO ANALGESIA BY INHALING ANALGESIC

This article deals with analgesia by inhaling analgesic. According to Chinese medical theories, TCM analgesics were chosen from the literature and folk prescriptions screened and proved by analgesic tests on animals. A reasonable prescription was made up and the drug inhaled. Its analgesic effect was superior to that of dolantin injection (3 mg/ kg body weight, intraperitoneal injection). Clinical trials showed its analgesic effect in 3-10 minutes and it lasted for more than 2 hours in over 70% of the cases for a total effective rate of 94.6%. The drug is absorbed quickly and acts directly on the nerve center. Its use is not addictive.
