Most of the gastric diseases seat in the mucosa, and the present investigation was undertaken in order to see if amogastrin, a synthetic tetrapeptide, was capable of enhancing gastric accretion of intravenous 99mTc pertechnetate in man as well as in the rabbit. Improvement of gastric scintigraphy was achievable with a pretreatment of the agent by increasing the gastric accretion and reducing the background radioactivity in the liver and small intestinum.
大多数胃部疾病位于黏膜层，本次研究旨在探究一种合成四肽——氨基胃泌素是否能够增强人体及兔子静脉注射高锝[99mTc]酸盐后的胃部摄取。通过增加胃部摄取并降低肝脏和小肠的本底放射性，对该药物进行预处理可实现胃闪烁显像的改善。
