实验用恶性疟原虫越南 FCR-1/FVO,冈比亚 FCR-3/FMG 及 FCR-4/6252三株,以 Trager 氏等的方法培养。在新培养第4天原虫血症达6～12％时,取标本作电镜观察。另用生理胶(Physiogel)将内含较多滋养体及裂殖体的红细胞与环状体及未感染的红细胞分开作电镜观察。结果如下:FCR-4株在连续培养了3个月后,感染较成熟原虫的红细胞表面,结节较另两株大而少;培养至18个月时,约50％表面失
Three strains of FCR-1 / FVO of Plasmodium falciparum Vietnam, FCR-3 / FMG of Gambia and FCR-4/6252 were cultured in the method of Trager et al. In the fourth day of protozoospermia training up to 6 ~ 12%, take specimens for electron microscopy. Another physiology gel (Physiogel) containing more trophozoites and schizonts of red blood cells and the ring and the uninfected erythrocytes separately for electron microscopy. The results were as follows: After 3 months of continuous culture, FCR-4 infected erythrocyte surface more mature protozoa, nodules than the other two large and less; cultured to 18 months, about 50% of the surface loss
