Protective Effect and Mechanism of Total Flavones from Rhododendron simsii Planch on Endothelium-Dependent Dilatation and Hyperpolarization in Cerebral Ischemia-Reperfusion and Correlation to Hydrogen Sulphide Release in Rats
Figure 2
The enhancement of TFR on the outward current in VSMC from middle cerebral arteries of rats subjected to global cerebral ischemia-reperfusion. (a) The trace of outward current in one VSMC, A: control, B ~ D: 300,900 and 2700 mg/L TFR and (b) the curve of current-voltage relationship. (); effect of TEA on the TFR-induced enhancement of outward current in VSMC from middle cerebral artery of rats subjected to global cerebral ischemia-reperfusion. (c) The trace of outward potassium current in one VSMC. A: TFR 2700 mg/L, B: TEA 1 mM + TFR 2700 mg/L and (d) the curve of current-voltage relationship. . Values are presented as means ± SE. , , compared with control group. compared with TFR (2700 mg/L) group. Comparisons were performed by unpaired Student’s -test.
