【摘要】 为探讨母乳中生长抑素的存在、变化规律及作用,应用放射免疫法系列观测30名正常哺乳产妇乳汁及相对应的血浆中生长抑素水平。结果:母乳生长抑素水平3倍～4倍于母血。母乳中该激素水平自产后7天起持续显著下降(P均<0.05),至产后3月其变化趋于平缓。结果表明,母乳中高浓度的生长抑素极可能有助于维持新生儿消化机能平衡;降低哺乳妇女乳腺癌发病率。更多还原

【Abstract】 To study the existence, change and function of somatostatin in human milk, radioimmunoassay was used to detect a series of somatostatin levels in the milk and the corresponding plasma of 30 normal nursing mothers. The somatosta-tion levels in the milk are 3 to 4 times those in the plasma. It begins to lower significantly in succession since 7 days postpar-tum (p all<0. 05) , and then remains stable since 3 months postpartum. The high - level somatostation in human milk may facilitate the homeostasis of neonatal digestive function and reduce the incidents of breast cancer in nursing mothers.更多还原
