目的：用低压电流刺激动物足底部并观察消化器官的形态学变化，以探讨现代医疗仪器使用过程中可能引起的组织损伤。方法：实验组动物每天定时给予80～140V交流电流的刺激，第16天处死动物并进行组织学计量分析。结果：应激组肝细胞、肝血窦、门管区发生明显损伤；2、小肠腺细胞、平滑肌细胞形态发生明显变化．结论：低压电流在一定务件下可明显改变消化组织的结构．“,”Purpose: To probe into the tissue damnification in progress of using modern madical instruments, the degest organs variation of low-voltage alternating current stimulation on thenar was observed. Method: the animals of experiment group were stimulated with 80V- 140V alternating current on time every days. At day of sixteenth these animals were killed,and liver and intestine histology were analyzed. Result: 1.the damnifications were distinctly in hepatocytes、hepatic sinusoid and portal area .2.the gland cells of small intestin and the cells ofsmooth muscle altered distinctly in morphology. Conclusion:Low-voltage alternating current could change the configuration of degest organs.
