近年来采用苯(?)咪唑、甲苯咪唑和丙硫咪唑治疗包虫病取得一定的成绩;然而,这些药物对病人的疗效从治疗到无效差别很大。目前寄希望于棘球蚴及其原头蚴通透特性和合理化疗途径研究。环亮氨酸和α-氨基异丁陵(AIB)为二种非代谢氨基酸,在缩小膜壳绦虫中吸收性很好,本文报告原头蚴对这两种氨基酸的吸收性。材料与方法 In recent years, the use of benzene (?) Imidazole, mebendazole and albendazole treatment of hydatid disease to achieve some success; however, the efficacy of these drugs from treatment to treatment vary widely. At present, we hope that the Echinococcus granulosus and its protoscoleces permeability and rational chemotherapy approach. Cyclic leucine and α-aminoisobutyronitrile (AIB) are two kinds of non-metabolizing amino acids, which have good absorption in the reduction of tapeworm. This paper reports the absorption of these two kinds of amino acids. Materials and Methods
