本文探讨下丘脑饮食中枢(摄食中枢——下丘脑外侧区,LH和饱中枢——下丘脑腹内侧区,VMH)八肽胆囊收缩素(CCK-8)对清醒大鼠胃运动的调节作用。胃收缩运动采用应力传感器记录;中枢和外周给药分别经脑内埋植注射套管和颈外静脉插管;用微电极记录
This article investigates the regulatory effect of cholecystokinin (CCK-8), an octapeptide, in hypothalamus diet center (feeding center - lateral hypothalamus, LH and saturatostasis - hypothalamic ventromedial region) on gastric motility in conscious rats. Stomach contractions were recorded using stress sensors. The central and peripheral administrations were implanted with an injection cannula and a jugular vein cannulated respectively in the brain. Microelectrode recording
