methods ghrelin was microinjected into pvn in rats and the antral motility and electrical activity were measured by extraluminal force strain gage transducers and electrodes.
采用核团内微量注射药物、应力传感器引导胃运动及银丝电极同步记录胃电活动等方法。
changes in antral motility induced by pentagastrin (g5) microinjected into the dor-sal vagal complex (dvc) were investigated in fasting conscious rats.
