While erthrocyte,hemoglobin and Hela cell were under oxidative damage induced by the hydrogen peroxide(H_2O_2) or tert-butyl hydroperoxide(TBHP) on different concentrations of dihydromyricetin,hemolysis rate of erythrocyte and methemoglobin converted from hemoglobin was estimated by ultraviolet-visible absorption spectroscopy.

[Results]The rates of neurasthenia,decrease of white blood cells and hemoglobin and the average level of MetHb were siginificantly higher in the exposure group than in the control group(P﹤0.
[结果]接触组神经衰弱症状、白细胞和血红蛋白偏低率、高铁血红蛋白平均含量均显著高于对照组(P﹤0。
Yet, such solution is unstable; there are marked rise in MetHb content and visible change in molecular distribution upon storage.
