| Abstract: | Objective To observe the effects of chronic stress on behavior and body weight of rats.Methods Chronic forced-swimming was used as stress model.Behavioral detector was applied to observe motor activity;elctronic animal scale was used to weigh the rats.Results Motor activity in stress group was significantly higher than that in control group( P <0.01),the stressed rats showed more times of defecate and emiction and more modified behavior.Body weight gain in stress group was significantly lower than that in control group( P <0 01).Conclusion Chronic forced-swimming could increase motor activity and suppress weight gain of rats. |
