【摘要】 目的 探讨垂体腺瘤患者血浆神经肽Y与生长激素之间的相关关系。方法 收集82例垂体腺瘤患者空腹静脉血3ml,进行血浆神经肽Y放射免疫测定分析,并与生长激素水平进行相关分析。初步探讨神经肽Y与生长激素之间的相关性。结果 促性腺激素细胞腺瘤患者中血浆神经肽Y与生长激素呈负相关。而在其他组别中神经肽Y与生长激素均无相关。结论 神经肽Y参与了垂体腺瘤病理生理状态中下丘脑-垂体轴生长激素的调节,可能与垂体腺瘤的发生有关。更多还原

【Abstract】 Objective To investigate the correlation between plasma neuropeptide Y (NPY) and growth hormone (GH) in patients with pituitary adenoma. Methods Fasting venous blood (3 ml per patient) was collected from 82 patients with pituitary adenoma. The level of plasma NPY was measured using radioimmunoassay, and the correlation with GH was analyzed. Results The level of plasma GH was negatively correlated with NPY in patients with gonadotropin cell adenoma but not in those with pituitary adenoma of other cell-types. Conclusion NPY is involved in the regulation of growth hormone production from the hypothalamus-pituitary axis in pathological conditions, and is possibly associated with development of pituitary adenoma.更多还原
