Effect of Salvianolic Acid B on Mitochondrial Function of Cerebral Ischemia in Mice

摘要

The effects of salvianolic acid B (SalB) on the mitochondrial membrane potential (MMP), calcium, and apoptosis of neurons with cerebral ischemia in mice were investigated using an acute cerebral ischemia model established by ligating the bilateral common carotid arteries in mica. The MMP, the intracellular cal-cium concentration, and the apoptosis rate of cortical neurons were measured at 6 min, 12 min, 18 min, 24 min, and 30 min after cerebral ischemia by a flow cytometer. The experiments show that SalB increases the MMP and reduces the intracellular calcium and the apoptosis rate at different stages of the cerebral ischemia in mice. The results show that the protective mechanism of SalB on cerebral ischemia enhances the MMP and maintains intracellular calcium homeostasis.
