摘 要: | 用CEAE DE-52分离纯化的锥虫,经超声波粉碎后离心,上清经硫酸铵沉淀,再经Sephadex G-200分子筛层析,DEAE Cellulose ED-52离子交换层析,2’,‘ADP-Sepharose层析得到纯化。筛选到抗蠕虫药奥芬哒唑(Oxfendazole)对TR有抑制作用。但对治疗锥虫病没有作用;兔抗TR抗体与安锥赛共同注射人工感染锥虫病的小白鼠,可增加安锥赛对锥虫病的疗效。

THE STUDIES ON TRYPANOTHIONE REDUCTASE OF TRYPANOSOMA EVANSI |

Abstract: | Trypanosoma evansi was purified by DEAE cellulose DE 52.After ultrasonication and centrifugation,TR was purified by ammonium sulfate precipitation,gel filtration chromatography,ion exchange chromatography,and affinity chromatography.One antihelminth drug Oxfendazole inhibited 50% of TR activity in vitro,but had no effect on treating trypanosomiasis.Antrycide worked together with rabbit antiserum of TR to increase the treating effect of the drug on trypanosomiasis. |
