A preparation method of
chronic hepatic injury complicated with stress depression
rat model comprises selecting male Wistar rat (
body weight of 180-220 g), acclimating for one week, performing
open field test ethology screening, and selecting rat having close integration; normally drinking and eating for the first week to the fourth week, and performing
hypodermic injection of 40% CCL4 1ml / kg (twice per week); normally drinking and eating from the fifth to the twelfth week, performing
hypodermic injection of 40% CCL4 1ml / kg (twice per week), and performing gastric
perfusion of normal
saline (one time per day); normally drinking and eating in the thirteenth week, and performing gastric
perfusion of normal
saline (one time per day); performing
open field test in the fourteenth to sixteenth week (one rat per cage), normally drinking and eating, performing gastric
perfusion of normal
saline (one time per day), and offering chronic stress stimulation; and weighing in 112th day, and performing sweet
water consumption and
open field test. The preparation method provides reference for modeling research of
chronic hepatic injury complicated with stress depression, provides effective experiment base for
clinical diagnosis of hepatopathy complicated with depression, and provides experimental
verification means for the research of
drug for treating the hepatopathy complicated with depression.
