【摘要】 探讨人绒毛膜促性腺激素（hCG）是否具有垂体促甲状腺激素（TSH）样作用。方法:应用放射免疫方法（RIA）对65例旱孕妇女hCG与甲状腺激素水平进行测定。结果:早孕妇女Ⅰ组（停经35—50天）3,3’,5’-三碘甲状腺原氨酸（rT₃）水平升高,与正常对照组差异显著（P<0.01）;早孕妇女Ⅱ组（停经51—80天）甲状腺素（T₄）、游离甲状腺素（FT₄）、rT₃水平均升高,与正常对照组差异显著（P<0.01）;而两组早孕妇女的三碘甲状腺原氨酸（T₃）、游离三碘甲状腺原氨酸（FT₃）水平与正常对照组无明显差异（P>0.05）。结论:hCG具有TSH样作用,早孕妇女甲状腺激素水平升高为hCG促使甲状腺功能增强所致。更多还原

【Abstract】 To study whether hCG can affect thyroid likeTSH.Methods We detected the serum levels of hCG and thyroidhormone in 65 early pregnant women by RIA.Results We dividedthe early pregnant women into two groups.Group Ⅰ:the womenhave no menstruation for about 35 days to50 days.Group Ⅱ:thewomen have no menstruation for about 51 days to 80 days.The serumlevel of rT3 in Group Ⅰ were remarkably higher than those in NormalGroup (P <0.01).The serum level of T4,FT4 and rT3 in Group Ⅱ wereremarkably higher than those in Normal Group (P<0.01).But thedifference between the serum level ofT3 and FT3 in early pregnantwomen and those in Normal Group was not significant (P >0.05).Conclusion hCG can affect thyroid like TSH.The reason whythe serumlevel of thyroid hormonein early pregnant womenbecomes higher is that hCG can increasethe thyroid function.更多还原
