Abstract:
Objective To explore the changes of atrial natriuretic peptide(ANP)and parathyroid hormone(PTH)in umbilical cord blood of newborn infants with intrauterine growth retardation(IUGR)and their relationships with electrolytic.Methods A total of 71 IUGR infants borned between Jan.2006 and Aug.2007 were enrolled in this study.Another 40 normal appropriate for gestational age neonates were selected as control group.The study group were divided into 2 groups:mature IUGR group(n=29)and premature IUGR group(n=42).The samples of umbilical cord blood of every group were collected at the time of delivery,and ANP,PTH levels in umbilical cord blood were mea-sured by radioimmunoassay.The sodium,calcium levels in their peripheral vein were measured simultaneously.Results 1.Compared with control group[(0.78?0.42)?g/L],the ANP levels of premature IUGR group[(1.26?0.47)?g/L] and the mature IUGR group[(1.09?0.51)?g/L] were significantly increased(t=5.98,2.76 Pa0.05).The calcium levels of the premature IUGR group[(1.85?0.37)mmol/L]significantly decreased(t=1.93 P0.05)compared with control group [(2.02?0.44)mmol/L].3.The serum sodium level was negatively correlated with the umbilical ANP level(r=-0.93 P
