- During Plasmodium malaria parasite infection in a human, the intraerythrocytic stages lead to the clinical manifestations of the disease, especially hypoglycemia. Hypoglycemia is a recognized feature of severe malaria and linked with a high risk of mortality for children. Hence, the present study aimed to investigate the protective effect of T. crispa stem extract on hypoglycemia induced by P. berghei infection tested with a mouse model. ICR mice were inoculated with 1 × 107 parasitized erythrocytes of P. berghei ANKA (PbANKA) by intraperitoneal injection and given 50, 100, and 200 mg/kg of ethanolic extract for 4-consecutive days. The results showed that T. crispa stem extract exerted a protective effect (100%) on hypoglycemia induced by PbANKA infection at doses of 100 and 200 mg/kg. A significantly (p < .05) prolonged mean survival time (28.0 ± 1.9 days) of the extract treated mice was also observed. Additionally, no effect on blood glucose levels was seen in normal mice treated with all doses of extract. It can be concluded that T. crispa stem extract may have beneficial properties in protecting against hypoglycemia, and in increasing survival time during malaria infection.
