RESUMO
Objective To observe the effect on IL-2,TNF,TGF in uterus and serum,and IL-2RmRNA in spleen of menopausal rats with preventive accupuncture on Guanyuan point,and analysis the mechanism.Methods 112 ten month-aged SD female rats examined by vaginal smear were chosen and divided into seven groups.And another 16 three point five month-aged SD female rats were another group.Radio-immunity and hybridiztion in situ methods were applied to observe the effect on IL-2,TNF,TGF in uterus and serum and IL-2R mRNA in spleen of 12,14 and 16 month-aged menopausal rats with preventive accupuncture on Guanyuan point(twice a week,eight weeks continued) in 10th month.Results Compared with the normal group,IL-2,TGF in uterus and serum and TNF in uterus of menopausal rats reduced,TNF in serum came down in the 12th month and went up in 14th and 16th month,IL-2R mRNA in spleen decreased.Compared with the same-aged model group,IL-2,TGF of serum and uterus and TNF in uterus increased.TGF in serum of 14 and 16 month-aged group,IL-2 in uterus of 12 and 16 month-aged group,TNF in uterus of 12 month-aged group and TGF in uterus of 12 and 16 month-aged group rised significantly(P
