Abstract:
OBJECTIVE： To study improvement effects of different proportions of total glucosides of ginseng （TGG）， total glucosides of moutan cortex （TGM） and paeonol containing serum on the injury of human umbilical vein endothelial cells （HUVEC） injury induced by hydrogen peroxide （H2O2）， screen the optimal proportion and investigate its mechanism. METHODS： The rats were randomly divided into blank group （distilled water）， TGG group （TGG， 2.025 g/kg）， TGM group （TGM， 4.05 g/kg） and paeonol group （paeonol， 1.08 g/kg）， with 12 rats in each group. They were given relevant medicine twice a day for consecutive 7 days. 1 h after last medication， the blood samples were collected via abdominal aorta to prepare drug containing serum. Using survival rate of HUVEC as evaluation indexes， different proportions of TGG， TGM and paeonol containing serum as factors， L9（34） orthogonal test was designed to optimize the optimal proportion of 3 kinds of drug containing serum. HUVEC were divided into blank group， model group， TGG group， TGM group， paeonol group and optimal proportion group. Except that blank group were treated with relevant medium， other group were treated with 1.2 mmol/L H2O2 to induce HUVEC injury， and then TGG group （volume fraction of drug containing serum was 0.000 5％）， TGM group （volume fraction of drug containing serum was 0.000 5％）， paeonol group （volume fraction of drug containing serum was 1％） and optimal proportion group were intervened with drug containing serum. The levels of LDH， NO and ET-1 in cells were detected by microplate method and ELISA. RESULTS： The optimal proportion of drug containing serum were TGG 0.000 5％， TGM 0.000 5％ and paeonol 1％. Compared with blank group， the levels of LDH and ET-1 were higher in model group （P＜0.01）， while NO level was lower （P＜0.05）. Compared with model group， the levels of NO were higher in TGG group， TGM group and optimal proportion group （P＜0.01）， while the levels of LDH and ET-1 were lower （P＜0.05 or P＜0.01）. Compared with TGG group， TGM group and paeonol group， the level of LDH was lower in optimal proportion group （P＜0.05 or P＜0.01）， while the level of NO was higher （P＜0.05 or P＜0.01）. CONCLUSIONS： TGG and TGM combined with paeonol can significantly improve HUVEC injury induced by H2O2， and the mechanism of which may be associated with the decrease of LDH and ET-1 and the increase of NO.
