摘　　要：The polycystic ovary syndrome (PCOS) model was established in fats and correlation between the expression of macrophage migration inhibitory factor (MIF) and cytokinesis with the MAPK signalling pathway in the rat ovary was measured. The PCOS model in rats was established by dehydroepiandrosterone (DHEA).Thirty sexually immature female Sprague-Dawley rats were randomly and equally assigned to three groups:control group,PCOS group,and PCOS with high-fat diet (HFD) group.Serum hormones were assayed by radioimmunoassay (RIA).The ovaries'were immunohistochemically stained with MIF,and the expression of MIF,p-JNK and p-p38 was detected by Western blotting in ovaries.The serum testosterone level,LH concentration,LH/FSH ratio,fasting insulin level and HOMA IR index in the PCOS group (6.077±0.478,13.809±1.701,1.820±0.404,10.83±1.123 and 1.8692±0.1096)and PCOS with HFD group (6.075±0.439,14.075±1.927,1.779±0.277,10.20±1.377 and 1.7736±0.6851)were significantly higher than those in the control group (4.949±0.337, 2.458±0.509,1.239±0.038,9.53±0.548 and 1.5329±0.7363),but there was no significant difference between the PCOS group and PCOS with HFD group.The expression levels of MIF,p-JNK,and p-p38 in the PCOS group (0.4048±0.013,0.6233±0.093 and 0.7987±0.061)and PCOS withHFD group (0.1929±0.012,0.3346±0.103 and 0.3468±0.031)were obviously higher than those in control group (0.2492±0.013, 0.3271±0.093 and 0.3393±0.061),but no Significant difference was observed between PCOS group and PCOS with HFD group.It was suggested that MIF may participate in the pathogenesis of PCOS through the MAPK signalling pathway in PCOS rats induced by DHEA.
