In vivo combination therapy of chloroquine and stigmasterol against Plasmodium berghei induced pathologies in mice

摘要

Objective:To investigate the effect of combination therapy of chloroquine and stigmasterol on Plasmodium(P.)berghei malaria-induced organ pathologies.Methods:Totally 35 mice weighing 20-30g were placed into 7 groups of 5 mice each and distributed as uninfected administered 100 mg/kg BW stigmasterol,uninfected administered only feed and water ad libitum,infected with P.berghei and administered 50 mg/Kg BW stigmasterol,100 mg/kg BW stigmasterol,100 mg/kg BW stigmasterol plus 5 mg/kg BW chloroquine,and 5 mg/kg BW chloroquine.The last group of mice served as P.berghei infected and not treated control.The levels of parasitemia,packed cell volume,and other biochemical parameters were measured.Results:Combination therapy of P.berghei infection with stigmasterol and chloroquine did not significantly(P>0.05)reduce parasitemia level while stigmasterol treatment alone significantly(P0.05)altered upon treatment with both doses of stigmasterol as well as the combination therapy.Conclusions:This study concluded that the combination of stigmasterol and chloroquine could combat anemia and some organ pathologies associated with P.berghei infection.
