查询词典 nitric oxide

After 24 hours, all rats were anesthetized again and their left common carotid arteries were cannulated to facilitate blood withdrawal for serum sample. The contents of tumor necrosis factor-a and interleukin-6 (IL-6) in serum were determined before and after experiment by ELISA; the activity of superoxide dismutase and content of malondialdehyde were determined by xanthinoxidanse method and modified TBA microdetermination. The content of NO2(superscript -)/NO3(superscript -), and activity of nitric oxide synthase and inducible NOS were determined by nitrate reductase method, and chemical chromogenic reaction, respectively; the immunoglobulin G, IgA, IgM and complement 3 (C3) and C4 were determined by immunoprecipitation method before and after experiment.
