Abstract
- Objective: To observe the effect of salvianolic acid B (SalB) on high energy phosphate and activity of ATPase of cerebral ischemia in mice, and to study the role of SalB on hydrocephalus further.<br />Method: NIH mice were divided into four groups randomly: Sham-operated group, cerebral ischemia group, SalB-treated group and Nimodipine (Nim)-collated group. In Sal B-treated group, mice were injected with SalB (22.5 mg x kg(-1)) in vena caudalis at 30 min before the experiment. In Nim-collated group, Nim (0.03 mg x kg(-1)) was injected into tail vein at the same time, while the mice in Sham-operated group and cerebral ischemia group were injected the same volume normal saline. The acute cerebral ischemia model was established by ligating bilateral common carotid arteries for 30 min in mice, then the mice were killed and the content of adenosine triphosphate (ATP), adenosine diphosphate (ADP), adenosine monophosphate (AMP), phosphocreatine (PCr) were observed, and the cerebral energy charge (EC) was computed. At the same time, activity of Na(+) -K(+) -ATPase and Ca2(+) -ATPase, content of water in brain tissue were measured.<br />Result: Compared with cerebral ischemia group, EC and content of ATP, ADP, PCr in SalB-treated group heightened evidently (P < 0.01). Moreover, activity of Na(+)-K+ ATPase and Ca2+ ATPase in SalB-treated group had a remarkable increase (P < 0.01). But the content of water in brain tissue decreased markedly (P < 0.05).<br />Conclusion: The mechanism that SalB can relieve content of water in brain tissue of cerebral ischemia in mice, may be associated with improving the content of high-energy phosphoric acid compounds and enhancing the activity of ATPase.
