Abstract

Background Leukocytes play an important role in the elimination of malaria infection. The leukocyte profile upon elimination of the malaria parasites that have been exposed to antimalarials and are subsequently capable of faster growth has not been researched. The aim of this research was to evaluate the role of mouse leukocytes in the elimination of parasites as shown by the leukocyte profile.Methods An experimental research with post test only control group design was conducted involving 24 male mice of the Swiss Albino strain weighing 20 g -30 g, and 2.5 months old. They were randomized into four groups: two control groups (K1, KP) and two treatment groups (P1, P4). Artemisinin at a dose of 0.04 mg/g body weight was given to the mice for 3 days, starting 2 days after infection. The leukocyte profile was observed on the 2nd, 5th, 8th, and 10th day after infection. The results were analyzed by two-way Anova.Results As shown in treatment control group KP and treatment group P4, P. berghei that had been passaged in the mice and were still viable after repeated exposure to artemisinin, may cause changes in leukocyte profile. On the 10th day of infection, the neutrophil percentage in group P1 showed a significantly different decrease when compared with the other groups (K1, KP and P4) (p<0.05).Conclusion Repeated exposure to artemisinin of mice infected with P. berghei can cause changes in neutrophil profile in mice.

Abstract

BACKGROUND The presence of Plasmodium falciparum resistance and decreased efficacy of artemisinin and its derivatives has resulted in the issue of malaria becoming increasingly complex, because there have been no new drugs as artemisinin replacements. The aims of this research were to evaluate in vitro changes in ultrastructural morphology of P. falciparum 2300 strain after exposure to artemisinin. METHODS The research used an experimental design with post test only control group. Cultures of P. falciparum 2300 strain in one control and one mutant group were treated by exposure to artemisinin at IC50 10-7 M for 48 hours. Ultrastructural phenotypic examination of ring, trophozoite and schizont morphology and developmental stage in the control and mutant group were done at 0, 12, 24, 36, 48 hours by making thin blood smears stained with 20% Giemsa for 20 minutes and examined using a microscope light at 1000x magnification. RESULTS Dormant forms occurred after 48 hours of incubation with IC50 10-7 M artemisinin in the control group. In the mutant group, dormant forms, trophozoites with blue cytoplasm and normal schizont developmental stages were seen. Ultrastructural phenotypic morphology at 0, 12, 24, 36, 48 hours showed that in the control group dormant formation already occurred with exposure to IC50 10-7 M, while in the mutant group dormant formation occurred only with exposure to IC50 2.5x10-5 M. CONCLUSION Exposure to artemisinin antimalarials in vitro can cause phenotypic morphological changes of dormancy in P. falciparum Papua 2300 strain.
