Objective To observe the regulating effect of taurine on the function of peritoneal macrophages of mice in vitro. Methods Mouse peritoneal macrophages were collected and the cell concentration was adjusted to 2 ×105/m L. The mouse peritoneal macrophages were divided into 5 groups,which were normal control group,LPS control( LPS final concentration 1 μg/m L),3 dose of taurine groups( final concentration of taurine was5 μg/m L,50 μg/m L and 500 μg/m L,respectively). The IL-12,TNF-α,IL-1,IL-6 in macrophages su...
