曾在临床上观察到很多蛔虫病患儿发生维生素缺乏引起的眼部症状。本文作者研究了感染蛔虫的儿童对维生素甲的吸收。5名无蛔虫病的正常儿童和6例蛔虫病患儿,年龄为2～6岁,每个儿童口服4微居里的retinylacetate(11,12-~3H_2),同时给服单剂量1,000微克冷的维生素A,以后4天内收集24小时小便和粪便样本。于第2天给蛔虫病患儿口服单剂量2.5克枸橼酸哌哔嗪,在3天内收集排出的虫体。小便和粪便样本的放射性物质用液体闪烁分光器测定,虫体以生理盐水洗涤后,用80%乙醇生理盐水制成匀浆,
Many clinically observed ascariasis in children with vitamin deficiency caused by eye symptoms. The authors studied the absorption of vitamin A in children infected with roundworms.
