Prophylactic effects of Kaempferia Galanga against Plasmodium berghei: in vivo study

Abstract

Recently, medicinal plants have been the main source in treating malaria. Kaempferia galanga was investigated as an antioxidant, and anti-inflammation. In vivo study of K. galanga had been verified as antimalarial for severe malaria. The objective of this study is to investigate the chemoprophylactic effect, body composition, and blood parameters of K. galanga against Plasmodium berghei. The prophylactic effects were determined by employing K. galanga (50; 100 and 200 mg/kg) in mice infected with P. berghei. Mice were subdivided into 4 groups (control negative and 3 treatment groups). The treatment groups received K. galanga daily for 3 days before the inoculation of P. berghei. Each mice were inoculated with the infected blood containing 106 of P. berghei. Parasitemia and body weight were calculated every day until 5 days post-inoculation, and the blood parameters was monitored in day 5. The parasitemia on the fifth days after inoculation revealed a significant suppresses effect compared to control (p<0.05). The suppressed effect by doses 50 mg/kg; 100 mg/kg; 200 mg/kg and negative control were 0.83%; 1.96%; 2.82%, and 17.8% respectively. The body weight on treatment groups was normal, but the control group decreased (p<0.05). The blood parameters on treatment groups were normal compared to control group. The K. galanga possess the prophylactic effect, normal weight and blood parameters against Plasmodium berghei.
