神经肽丫(Neuropeptide Y,NPY)和神经降压素(Neurotensin,NT)属于生物活性多肽物质,在哺乳动物脑组织中分布广泛,对心血管、消化系统及中枢神经系统具有复杂的生物学效应。据文献报告,肾上腺嗜铬细胞瘤及人某些癌组织中可有大量NPY或NT存在。脑组织是中枢神经系统肿瘤的好发部位,为观察NPY、NT在脑瘤患者中的变化及意义,我们检测了脑瘤患者肿瘤组织及肿瘤周围正常组织NPY、NT含量,并观察了相应患者和正常人血浆含量变化。现报告如下 Neuropeptide Y (NPY) and Neurotensin (NT) are bioactive peptides that are widely distributed in mammalian brain tissue and have complex biological effects on cardiovascular, digestive and central nervous system . According to the literature, adrenal pheochromocytoma and some cancerous tissue may have a large number of NPY or NT exist. In order to observe the changes and significance of NPY and NT in brain tumor patients, we detected the content of NPY and NT in tumor tissues and normal tissues around the tumor, and observed the corresponding patients And normal plasma changes. The report is as follows
