摘要: 目的 对心理应激大鼠的部分福利相关指标进行检测并评价其福利水平。方法 选取8周龄雄性SPF级SD大鼠,使用电击旁观的方式对其进行心理应激,构建心理应激模型,观测大鼠的体质量增加、血压变化、脾脏系数和胸腺系数,实时荧光定量PCR和免疫组织化学分别检测大鼠肝细胞内核因子-κB(NF-κB) p65的mRNA和蛋白表达水平,酶联免疫吸附法(ELISA)测定血清白介素-2(IL-2)、肾上腺素(EPI)、去甲肾上腺素(NE)、促肾上腺皮质激素(ACTH)和皮质酮(CORT)水平。结果 与对照组相比, 实验组大鼠日常行为变化明显且体质量增加显著降低、血压升高(P<0.05),脏器系数差异无统计学意义(P>0.05),NF-κB p65的基因和蛋白表达显著升高(P<0.05),血清EPI、NE、ACTH和CORT水平提升而IL-2降低(P<0.05)。结论 电击旁观使实验组大鼠受到心理应激,心理福利受损,进而导致整体福利水平下降。在动物实验研究中,实验人员应对此加以重视,尽量避免对动物实验的不良影响。

Abstract: Objective To observe the effects of chronic stress on animal welfare related indexes in rats.Methods Eight weeks old SPF SD rats were subjected with chronic stress by electric shock observing.Body weight gain and blood pressure of the rats were recorded throughout the experiment.The expressions of mRNA and protein of nuclear factor-κB (NF-κB) p65 in liver cells were measured by real-time quantitative PCR and immunohistochemical method respectively when the experiment ended.Interleukin-2 (IL-2),epinephrine (EPI),norepinephrine (NE),adrenocorticotropic hormone (ACTH) and corticosterone (CORT) in blood were measured by enzyme-linked immunosorbent assay (ELISA).Results Related indexes of group test were compared with group control,the body weight gain were lower and blood pressure were higher (P<0.05).The expressions of mRNA and protein of NF-κB p65 were higher (P<0.05).The indexes of NE,EPI,ACTH and CORT were higher and IL-2 got lower (P<0.05).Conclusion The animal welfare would be infected by chronic stress,and should be paid attention to during the animal experiment studies.
