The Effect of Virgin Coconut Oil on TNFα and Cytochrome P450 Aromatase Levels in Obese Female White Rats (Rattus norvegicus) Induced with a High-Fat Diet

Abstract

Background: The high level of various proinflammatory cytokines due to adipocyte hypertrophy such as TNFα in obesity increases cytochrome-P450-aromatase, further inducing increased estrogen production, hypersecretion of Luteinizing Hormone and decreased Follicle Stimulating Hormone, resulting in impaired folliculogenesis, and chronic anovulation. Virgin Coconut Oil is rich in Medium Chain Fatty Acid and phytochemicals as anti-inflammatory. Aim: The aim of this study was to determine the effect of VCO on reducing TNFα and cytochrome-P450-aromatase levels in obese female white rats. Methods: Post test only control group, 24 rats were divided into 3 groups, namely: negative control group (K-), positive control group (K+), and treatment group (P). The K+ and P groups were induced using a high-fat diet for 10 weeks, then the P group was given VCO in weeks 7-10. On the first day of week 11, blood was taken from the orbital vein of the eyes of all rats for TNFα levels. Both examinations used ELISA kits. Data analysis used Shapiro Wilks normality test. The value of p>0.05, followed by hypothesis testing using one-way annova and post hoc Bonferroni. Results: Mean TNFα in the K- group: 141.71±8.87, K+ group: 15.09±19.30, P group: 162,09±13,57. Mean cytochrome-P450-aromatase levels in the K- group: 9.00±0.77, K+ group: 12.22±1.69, P group: 10.58±0.97. The mean levels of one way ANOVA analysis showed that the administration of VCO can significantly reduce TNFα levels (p=0.001) and significantly reduce Cytochrome-P450-aromatase levels (p=0.001). Conclusion: VCO administration can reduce TNFα levels and cytochorme-P450-aromatase levels in obese female white rats. Keywords: TNFα, cytochrome-P450-aromatase, infertility, obesity
