摘　　要：Objective To investigate the relationship between intrauterine growth retardation (IUGR) and endocrine parameters so as to assess the effects or the main endocrine ractors on IUGR. The concentrations of growth hormone(GH), insulin, T3, T4 and TSH were measured in umbilical cord blood, amniotic fluid and maternal serum.Methods The samples were collected from 23 pregnant women who were diagnosed as the full term IUGR, 42 normal full term pregnant women with normal infants’ weight were taken as control. Growth hormone and insulin were measured by radioimmunoassay. T3, T4 and TSH were investigated by micro-radioimmunoassay. Results The concentrations of growth hormone, insulin and T4 in umbilical cord blood were lower in IUGR than that in control group(GH4. 63μ/L vs 7. o1μg/L, insulin 1o. 68μIU/ml vs 31. 44μIU/ml, T487. 39nmol/L vs 138. 1onmol/L. P <o. o5, o. o5 and o. o5, respectively). The TSH concentration in umbilical cord blood was higher in IUGR than in control group (1o. 84μmIU/L vs 5. 75μmIU/L, P <o. o1 ). The concentration of growth hormone in maternal serum and the concentration of insulin in amniotic fluid were also lower in IUGR group than in control group(GH 1. 77μg/L vs 2. 74μg/L,P <o. o1, insulin 5. 84μIU/ml vs 15. 64μIU/ml, P <o. o1). Conclusion This study confirms that full term neonates with IUGR are abnormal in endocrine factors. The inadequacy of growth hormone may be one of the causes of IUGR. The relatlve scarcity of growth hormone and insulin seems to be a factor to compromise the fetus’ metabolism. Besides, the early hypothyrosis of infants with IUGR might protect them from unfavorable environment in the uterine.Objective To investigate the relationship between intrauterine growth retardation (IUGR) and endocrine parameters so as to assess the effects or the main endocrine ractors on IUGR.
