本文首先确定使用香草醛—浓硫酸比色法测匙羹藤酸含量。

Methods:The study group included 30 pregnant women diagnosed with PIH( 10 mild, 10 moderate, 10 severe). Thirty healthy pregnant women were selected as the control group. The serum was assayed for the activity of ACE by using color comparison method, hippuric acid used as the substrate.

选择轻、中、重度妊高征病人各10例为实验组，正常妊娠妇女30例为对照组，用马尿酸微量比色法检测血清中ACE活性，并进行对比分析。

These indicates bioactive peptides in Chinese forest frog skins have great potential for the exploitation and utilization. S_(180) cells were inoculated hypodermically at the concentration of 1×10~6 cells per mouse and the bioactive peptides in Chinese forest frog skins were resolved into aseptically distilled water to make injection liquid. After injected continuously 15 days, the inhibition rate of tumor was calculated. The induction of tumor cell apoptosis of active peptides in Chinese forest frog skins could be detected by morphological
