目的 不饱和脂肪酸对豚鼠胃窦平滑肌细胞钙激活钾电流的影响。方法 本实验在急性分离的豚鼠胃窦平滑肌上 ,利用膜片钳技术的全细胞记录法观察了外源性不饱和脂肪酸对豚鼠胃窦平滑肌细胞钙激活钾电流(IK(Ca) )的影响 ,及其作用机制。结果 结果发现AA明显增强豚鼠胃窦平滑肌细
Effect of Unsaturated Fatty Acids on Calcium - activated Potassium Currents in Gastric Smooth Muscle Cells of Guinea. Methods The effect of exogenous unsaturated fatty acids on the calcium-activated potassium currents (IK (Ca)) in antral smooth muscle cells of guinea-pigs was observed by patch-clamp technique in acutely isolated guinea pig gastric antral smooth muscle. And its mechanism of action. The results showed that AA significantly enhanced the smooth muscle of guinea pig gastric smooth muscle
