摘    要:目的:观察电针对吗啡戒断大鼠免疫器官及胸腺细胞凋亡的影响。方法:连续15d肌肉注射递增量吗啡,建立大鼠慢性吗啡成瘾模型,观察电针对吗啡戒断大鼠免疫器官胸腺、脾脏及其指数的影响,运用TUNEL法标记各组大鼠胸腺的凋亡细胞。结果:与正常组比,戒断组大鼠免疫器官胸腺、脾脏萎缩,重量下降(P<0.01),胸腺细胞凋亡率升高;电针组大鼠胸腺、脾脏萎缩减轻,重量上升(P<0.01),胸腺细胞凋亡率下降。结论:电针“足三里”穴具有保护免疫器官、抑制胸腺细胞凋亡的作用。

关 键 词:电针  吗啡戒断大鼠  细胞凋亡  TUNEL法

Abstract:Objective: To investigate the effect of electroacupuncture (EA) on thymus and spleen and apoptosis of thymocytes in morphine withdrawal rats. Methods: Rat abstinence syndrome model was established by continuous muscular injection of morphine (with the injected doses increasing gradually from 4 mg to 140 mg/kg, 1~3 times/d) to the hind limbs for 15 days. A total of 24 Wistar rats were randomly and evenly assigned to normal control group, abstinence syndrome (AS) group and EA (ST-36) group. The net weight of the thymus and spleen were detected and recorded.TUNEL method was applied to mark the apoptosis of thymocytes. EA (2~100 Hz, 1~2 mA) was applied to bilateral “Zusanli”(ST 36) for 30 min, once daily, continuously for 7days. Results: In comparison with normal control group, a significant decrease of the weight of both thymus and spleen, and the thymus index and spleen index was observed in AS group(P<0.01). Comparison between AS group and EA group showed that the weight of both thymus and spleen of EA group increased significantly than that of AS group, and both thymus index and spleen index of EA group were bigger than those of AS group (P<0.01), indicating that the effect of AS was reversed by EA. TUNEL method showed that the apoptosis rates of thymocytes in normal control, AS and EA groups were 5.7%, 51.1% and 31.8% respectively, displaying that EA could suppress AS-induced apoptosis of thymocytes. Conclusion: EA of ST-36 may protect the immune organ and inhibit the apoptosis of thymocytes, which may account, at least partly, for the suppression of EA on immune organ impaired by morphine.
Keywords:Electroacupuncture Abstinence syndrome Apoptosis TUNEL method
