Two methods for the assay of rifampicin in serum are described. The first is a conventional plate diffusion method, measuring concentrations down to 0.02 mug/ml, and the second a chemical extraction followed by measurement of the inhibition of uptake of (14)C-uridine by Staphylococcus aureus, which estimates in the range of 0.02 to 0.001 mug/ml. The methods were used to measure serum concentrations in man following doses of about 1050 mg and 75 mg rifampicin.
本文描述了两种测定血清中利福平的方法。第一种是传统的平板扩散法,可检测低至0.02微克/毫升的浓度;第二种是化学提取法,随后测定金黄色葡萄球菌对(14)C - 尿苷摄取的抑制作用,其估计范围为0.02至0.001微克/毫升。这些方法用于测定人体在服用约1050毫克和75毫克利福平后的血清浓度。
