title: [An experimental and clinical study on radix Salviae miltiorrhiae in the treatment of hepatocellular Ca2+ overload during hepatic ischemia/reperfusion injury].
abstract: In recent years there has been considerable interest concerning the role of hepatocellular Ca2+ overload which probably was a major factor in hepatic ischemia/reperfusion injury. We studied the effect of radix salviae miltiorrhizae (RSM) on cytosolic free calciumion concentration [(Ca2+)i](nM) in isolated hepatocytes in rats and patients with ischemia reperfusion by microflurometry using fluorescent (Ca2+)i indicator Fura-2/AM. Changes of lipid peroxide free radical (ROO.) signal ranges with in the liver tissue by ESR technique and those of hepatocellular ultrastructure by electronmicroscope were also observed. The results showed that RSM reduced levels of (Ca2+)i and ROO. Ymax (mm) ESR signal rangs. RSM had an effect on protecting hepatocytes against ischemia/reperfusion injury as a useful receptor-operated calcium channels (ROC) blocker.
