OBJECTIVES: To investigate the effect of magnesium isoglycyrrhizinate on the proliferation and oxidative stress of rat hepatic stellate cells (HSCs). METHODS: The effect of various concentrations of maganesium isoglycyrrhizinate on the proliferation of primary rat HSCs and HSCs strains were measured by making cell growth curves and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphennylterazolium bromide (MTT) colorimetric assay. Morphological changes of the rat HSCs were also studied. After rat HSCs were incubated with various concentrations of maganesium isoglycyrrhizinate and ferric nitrilotriacetate (Fe-NTA) for 24 hours, the activity of superoxide dismutase (SOD) and contents of malondialdehyde (MDA) in supernates were measured to observe the effect of magnesium isoglycyrrhizinate on the oxidative stress of rat HSCs. RESULTS: Compared with the control group, the proliferation of rat HSCs was significantly inhibited when the concentration of magnesium isoglycyrrhizinate in the medium reached a certain level range. In the oxidative stress induced by Fe-NTA, magnesium isoglycyrrhizinate, within a certain strength range, obviously enhanced the activity of SOD and decreased the contents of MDA in supernates of rat HSCs culture media. CONCLUSIONS: Magnesium isoglycyrrhizinate could significantly inhibit the proliferation of rat HSCs and it, within a certain strength range, exert protective effects in the oxidative stress induced by Fe-NTA.
