艾灸关元穴对老年大鼠下丘脑－垂体－甲状腺轴和IL－2的影响

老年大鼠大脑皮层ＮＥ、下丘脑ＴＲＨ、血清Ｔ３、Ｔ４、ＦＴ３、ＦＴ４和脾脏ＩＬ－２均明显低于青年组，血清ＴＲＨ、ＴＳＨ和ｒＴ３则高于青年组；而艾灸可明显提高老年大鼠降低的大脑皮层ＮＥ、下丘脑ＴＲＨ，血清Ｔ４和脾脏ＩＬ－２活性，降低老年大鼠升高的血清ＴＲＨ，提示艾灸关元穴可不同程度调整神经内分泌和免疫系统功能从而达到补肾固本。

The cerebral cortex NE,hypothalamus TRH,serum T_3,T_4,FT_3,FT_4,contents and spleen IL-2 activities in senile rats were lower than that in young rats obviously, while serum TRH,TSH and rT_3 contents were higher than that in young rats signifi- cantly.Moxibustion Guanyuan,however, could increase the reduced contents of NE in cerebral cortex,TRH in bypothalamus,T_4 in serum and the activities of IL-2 in spleen of the senile rats ,decrease the heightened con- tents of TRH in serum.The above results showed that moxibustion Guanyuan might modulate the function of neuroendocrine- immunesystem,so as to exert the effects of tonifying the kidney and enhancing the body resistance which in turn retarding the ag- ing.
