摘　　要：Objective: To explore the effects of Tetramethylpyrazine (TMP) and Radix Salviae Miltiorrhizae (RSM) on collagen synthesis and proliferation of cardiac fibroblasts. Methods: Using collagenase and pancreatin digested rat cardiac tissue assay to isolate cardiac fibroblasts (FB). Different dosage of TMP, RSM and norepinephrine were used to study their effects on the collagen synthesis and proliferation of cultured cardiac FB. Results: Compared with the control group, moderate or high dosage TMP and RSM could significantly inhibit the collagen synthesis and the proliferation of cultured cardiac FB. Moreover, low-dose TMP (50 mg/L) and low-dose RSM (3 g/L) could antagonize the collagen synthesis and the proliferation of cultured cardiac FB stimulated by NE (500μg/L). Conclusion: Both TMP and RSM can inhibit the collagen synthesis and proliferation of cultured cardiac FB processes.The mechanisms of these effects might be correlated to their Ca++ antagonistic action.
