OBJECTIVE: To investigate the effects of Radix Salviae Miltiorrhizae (RSM) on intracellular free calcium in hepatic stellate cells (HSCs). METHODS: After the model of hepatic fibrosis was established in SD rats, RSM [20 ml/(kg x d)] was given via gastrogavage to the rats of treatment groups while the same volume of 0.9% NaCl was given to the rats of control groups twice a day for 6 consecutive days. Then the blood sample was drawn from the inferior vena cava, and the serum was extracted for pharmacological studies. After 24 h incubation with 10% drug serum, HSCs were loaded with Fluo-3/AM, a Ca2+ marker, and were observed with laser scanning confocal microscopy (LSCM). RESULTS: By comparison with controls, both RSM pharmacological serums decreased [Ca2+]i in HSCs significantly in the condition of using Ang II or not (P<0.05). CONCLUSION: RSM decreased [Ca2+]i in activated HSCs, which may be one of important ways to block liver fibrosis.
