本文测定了38例健康新生儿和25例早产儿血心钠素、肾素、血管紧张素Ⅲ和醛固酮含量。结果显示健康新生儿生后3～7天组与8～28天组四种激素含量无显著性差异。动态观察结果表明生后24小时内心钠素明显升高,3天后达稳定水平。而醛固酮、肾素和血管紧张素Ⅲ含量较低,3天后逐渐升高。早产儿血心钠素、肾素和血管紧张素Ⅲ及血钠含量明显高于足月儿,醛固酮含量明显低于足月儿。
In this paper, 38 healthy newborns and 25 preterm infants were tested for atrial natriuretic peptide, renin, angiotensin III and aldosterone levels. The results showed that healthy neonates 3 to 7 days after birth and 8 to 28 days group four hormone content was no significant difference. Dynamic observation results show that within 24 hours after birth, atrial natriuretic peptide increased significantly, reached a stable level after 3 days. And aldosterone, renin and angiotensin Ⅲ content is lower, gradually increased after 3 days. Preterm children with blood atrial natriuretic peptide, renin and angiotensin Ⅲ and serum sodium levels were significantly higher than those of full-term children, aldosterone content was significantly lower than full-term children.
