摘要

154.8毫微克/公斤(600 R)的60Co全身照射在两周内造成50%的死亡率。照射前30分钟给予1-乙酰-3-苯基氨基硫代氨基盐酸盐(APTH)可防止这种死亡。照射消除了视上和室旁神经元核周的神经分泌物质,而APTH抵消了这一作用。APTH还增加了生物胺(5-羟色胺、儿茶酚胺和乙酰胆碱)的合成。

Biogenic amine response to whole body irradiation. Prevention by APTH.

60Co whole body irradiation with 154.8 mC/kg (600 R) resulted in a mortality of 50 per cent within two weeks. Administration of 1-acetyl-3-phenylamidine thiocarbamide hydrochloride (APTH) 30 min before irradiation prevented this mortality. Irradiation eliminated neurosecretory material from the perikaryons of the supraoptic and paraventricular neurons, whereas APTH counteracted this action. APTH also increased the synthesis of bioamines (5-hydroxytryptamine, catecholamine and acetylcholine).
