Abstract

目的: 探索对香豆酸(p-CA)对慢性束缚应激(CRS)诱导小鼠抑郁样行为的作用。方法: 实验分两批进行,第一批小鼠随机分成对照组(Control),慢性束缚应激组(CRS)和慢性束缚应激+p-CA组(CRS+p-CA),每组8只,其中慢性束缚应激小鼠每天接受4 h的束缚应激,连续束缚21 d,而对照组小鼠留在笼中不被打扰。第22日小鼠腹腔注射溶媒(10%吐温80)或p-CA(100 mg/kg),注射后1 h进行自发活动测试(LMA),注射后4 h进行强迫游泳测试(FST),注射后24 h进行悬尾测试。第二批小鼠随机分成慢性束缚应激组(CRS) ,慢性束缚应激+ANA-12(原肌球蛋白激酶B拮抗剂)组(CRS+ANA-12)和慢性束缚应激+p-CA组(CRS+ p-CA)慢性束缚应激+p-CA +ANA-12组(CRS+ p-CA +ANA-12),每组8只,4组小鼠每天接受4 h的束缚应激,连续束缚21 d。第22日小鼠腹腔注射溶媒(10%吐温80)或p-CA(100 mg/kg),ANA-12(0.5 mg/kg)在p-CA注射前30 min给药。注射后1 h进行自发活动测试(LMA),注射后2 h进行强迫游泳测试(FST),注射后24 h进行悬尾测试。结果: ①在实验一中,与Control组相比,CRS组小鼠强迫游泳和悬尾测试中不动时间显著性增多(P＜0.05);而与CRS组相比,CRS+ p-CA组小鼠不动时间显著性减少(P＜0.05,P＜0.01)。②在实验二中,与CRS组相比,CRS+ p-CA组小鼠强迫游泳和悬尾测试中不动时间显著性减少(P＜0.05);而与CRS+ p-CA组相比,CRS+ p-CA +ANA-12组小鼠强迫游泳和悬尾测试中不动时间显著性增多(P＜0.05)。结论: P-CA改善慢性束缚应激诱导小鼠抑郁样行为,TrkB受体可能介导了此作用。.
