【摘要】 电刺激大鼠丘脑下室旁核(Paraventricular Hypothalamic Nucleus PHN)引起胃内压明显下降。刺激前平均胃内压0.62±0.01kPa,刺激时下降至0.39±0.01kPa,与刺激前相比,差异有高度显著性(P<0.001)。胃内压变化率—37.1％。胃内压变化的潜伏期约3～5s,刺激停止后约2～5min才恢复至刺激前水平。本实验提示室旁核参与胃活动调节,并且可能由神经调节实现。更多还原

【Abstract】 Electrical stimulation of PHN could decrease intragastric pressure (IGP) obviously. IGP decreased from 0.62±0.01kPa to 0.39±0.001kPa in the course of electrical stimulation(P<0.001). The percentage of decrease was -37.1％. Potential period of IGP change was about 3～5s. IGP was restored in 2～Smin after stimulation stoped. Results showed that PHN regulated gastric activity possibly by the way of nerves.更多还原
