EFFECT OF DATE FRUIT (PHOENIX DACTYLIFERA L.) EXTRACT ON TNFα LEVELS AND BRAIN WEIGHT OF ALZHEIMER’S MODEL RATS

Abstract

Background: Alzheimer's disease (AD) is a neurodegenerative disorder marked by brain inflammation resulted in structural damage and brain dysfunction. Tumor necrosis factor α (TNFα) is a cytokine that plays an important role in inflammation. Dates fruit may help to fight oxidative stress and inflammation in the brain. Objective: To determine the effect of date fruit extracts on blood TNFα levels and brain weight of alzheimer’s model rats. Methods: This research is a laboratory experimental study by post-test only with control group design using alzheimer model rats. This study used 6 treatment groups with simple randomization. Each treatment group was represented by 8 Sprague Dawley rats. The normal control group (KN) was not induced by Hcy and was not given date palm extract, the negative control group (K-) was the Alzheimer's experimental rats which was not given the date palm extract, the positive group was the Alzheimer's experimental rats which was given the Donepezil (K+). Groups P1, P2, P3 were Alzheimer's experimental rats that were given date palm extract at a dose of 200, 400,800 mg / kgBW / day. The effect of date palm extract dosage on TNFα levels and brain weight were analyzed using the One Way Anova test followed by Tukey's post hoc test. Results: The difference in TNFα levels between groups showed a significant difference (p = 0.00). Meanwhile there was no significant difference in brain weight among all groups (p > 0,05). Conclusion: Date palm extract at doses of 200, 400, 800 mg / kgBW can decrease blood TNFα levels of Alzheimer’s model rats.
