A Study on Course of Infection and Haematological Changes in falciparum-Infected in Comparison with Artemisinin(s)‎-Treated Mice

الملخص EN

To find out the efficacy and effect of artemisinin derivatives on haematological indices, C57BL/6J mice were challenged with Plasmodium falciparum and treated with therapeutic doses of AS, AE, and AL.

Course of infection was studied in the infected and treated groups up to day 42.

Peak level of parasitaemia (38%) was observed on day 11 in infected group.

Haematological indices indicated significant (P<0.05) decrease in RBC, WBC, haemoglobin, packed cell volume, mean cell volume, and platelet counts in infected mice.

But all the parameters were restored to normal values, and significant (P<0.05) changes were observed in all drug-treated groups.

Insignificant changes were observed for MCHC (P>0.05) in all drug-treated groups.

Percent of peak parasitaemia was much reduced in AL- (3.2% on day 3) treated group in comparison with AE- (2.4% on day 4) and AS- (4% on day 2) treated groups.

Parasites were completely cleared on day 6 in AS group, day 5 in AE group, and day 4 in AL group.

Hence, our results strongly support that combination therapy has high efficacy rates than monotherapy.

No adverse effects were observed on haematological parameters when animals were treated with therapeutic dosages.
