目的通过慢性束缚应激(CRS)建立C57BL/6J小鼠抑郁症模型。方法C57BL/6J小鼠经体重、糖水偏好、旷场实验初筛后从中选择20只小鼠并随机分为正常对照(NC)组和CRS组2组,每组10只。对CRS组小鼠进行连续21 d,每天4 h的束缚刺激,并最终进行糖水偏好检测和强迫游泳检测。结果CRS组小鼠在水中不动的时间为(131. 70 ± 21. 65) s,明显长于NC组的(68. 88 ± 8. 43) s (P = 0. 0304)。CRS组小鼠0 ~ 24 h和0 ~ 48 h的糖水偏好百分比分别为(66. 21 ± 3. 24) %和(73. 25 ± 1. 50) %,均明显低于NC组的(79. 46 ± 3. 85) % (P = 0. 0196)和(80. 20 ± 2. 26) % (P = 0. 0248)。结论通过慢性束缚应激成功建立C57BL/6J小鼠抑郁症模型。 |

Objective To establish a chronic restraint stress (CRS) model of depression,using C57BL/6J mice. Methods Totally 20 C57BL/6J mice were screened by weight,sucrose preference,and the results of open-field test. Then,they were equally randomized into two groups: normal control (NC) group and CRS group. Mice in the CRS group were under restraint 4 hours a day and their behavioral changes were evaluated after 21 days. Results The immobility time was significantly longer in CRS mice [(131. 70 ± 21. 65) s] compared with controls [(68. 88 ± 8. 43) s](P = 0. 0304) . CRS mice showed a significant decrease in sucrose preference during the time 0-24 h [(66. 21 ± 3. 24) % vs. (79. 46 ± 3. 85) %,P = 0. 0196] and 0-48 h [(73. 25 ± 1. 50) % vs. (80. 20 ± 2. 26) %,P = 0. 0248]compared with controls. Conclusion The C57BL/6J mice CRS models of depression were successfully established. |
