Abstract

BackgroundCerebral malaria is a severe form of malaria caused by brain ischemia. Artesunate, an artemisinin derivative, is the standard WHO therapy for severe malaria. Tinospora crispa (brotowali) is a traditional plant with antiinflammatory, antioxidant and antiparasitic properties. The aim of this study was to determine the effect of combinations of artesunate and T. crispa extract on nuclear factor kappa-B (NFêB) and intercellular adhesion molecule-1 (ICAM-1) expression in the brain of mouse malaria models.MethodsThis was an experimental post-test only control group study using C57BL/6J mice infected with Plasmodium berghei, divided into 7 groups: negative control, positive control, group receiving artesunate 32 mg/kgBW, group receiving tinospora extract 3.5 mg/kgBW, and three groups receiving combinations of artesunate 32 mg/kgBW and tinospora extract 2.5 mg/kgBW, 3 mg/kgBW and 3.5 mg/BW, respectively. The expression of NFêB and ICAM-1 was measured by immunohistochemistry. One-way ANOVA was used to analyze the data.ResultsNFkB and ICAM-1 expression increased significantly in the positive controls compared to all other groups (p=0.000). NFkB expression was significantly lower in the groups receiving artesunate and tinospora at 3 mg/kgBW and 3.5 mg/kgBW, as compared with the artesunate only group (p=0.003; p=0.005) and the tinospora extract only group (p=0.001; p=0.003). NFkB expression in all combination treatment groups was similar to that in the negative controls (p>0.05), whereas ICAM-1 expression did not differ between single and combination treatment groups (p>0.05). ConclusionThe combination of artesunate and T. crispa extract is better in decreasing NFêB and ICAM-1 expression in the brain of mouse malaria models.

Abstract

BACKGROUNDCatechins inhibits apoptosis through anti oxidant and anti inflamation pathway. Catechins also increases brain-derived neurotrophic factor (BDNF). There was a few research that explained the role of catechins in traumatic brain injury (TBI). The objective of the study was to evaluate the effect of catechins administration on neurologic severity score (NSS) through apoptosis and neurotropic pathway in traumatic brain injury rat model.METHODSA post test only controlled group design was performed using traumatic brain injury rat (Rattus novergicus) model through weight drop models. It was devided into negative control group, positive control group, TBI+catechins 513 mg/kgBW, TBI+catechins 926 mg/kgBW, TBI+catechins 1113 mg/kgBW. NSS was measured in the first hours, day three, and day seven. The expressions of NFkB, TNFa, Bcl-2, Bax, caspase 3, caspase 8, BDNF, and the numbers of apoptosis cells were evaluated by imunohistochemystry method. One way Anova and Kruskal Wwallis were used to analyse the data.Results TNFa, caspase 8, number of apoptosis cells were significantly decreased on the seventh day administration compared to the third day administration (p<0.05). Catechins increased the expression of Bcl-2/Bax and BDNF significantly (p<0.05). Yet, there were no significant differences between expression of caspase 3, NSS, Bcl-2/Bax ratio, and BDNF toward third days administration of catechins compared with seven days administration (p>0.050).ConclusionsAdministration of catechins decreased NSS through inhibiting inflammation and apoptosis, as well as induced the neurotrophic factors in rat brain injury. Catechins may serve as a potential intervention for TBI.
