Neuroprotective Effect of Radix Trichosanthis Saponins on Subarachnoid Hemorrhage

Figure 5

RT saponins at 2 mg/kg/d significant inhibition of iNOS activity. (a) Decreased iNOS activity was observed in RT saponins at 2 mg/kg/d in brain cortex at 24 h of SAH; (b) iNOS activities in serum were lower than that of sham when treated with 2 mg/kg/d RT saponins after SAH. Data are expressed as the mean ± SD of three independent experiments. versus sham; versus SAH.
