Pomegranate extract cream enhances FGF and reduces IFN-gamma in excision wounds of wistar rats
Abstract
Wounds impose significant social and financial burdens, and effective healing requires regulation of growth factors and cytokines. Fibroblast growth factor (FGF) accelerates proliferation, angiogenesis, and tissue repair, whereas interferon-gamma (IFN-gamma) negatively affects the healing process. This study aimed to evaluate the effect of pomegranate (Punica granatum) extract cream on FGF and IFN-gamma levels in excision wound model rats. A true experimental design with post-test only control groups was conducted using 48 Wistar rats divided into 12 groups, with evaluations on days 3 and 7. Treatments included base cream, Bioplacenton, and pomegranate extract creams at 10% and 20% concentrations. FGF and IFN-gamma. levels were measured by ELISA and analyzed with Kruskal–Wallis and one-way ANOVA. The results showed significantly higher FGF levels in the 20% pomegranate extract group compared to controls on both day 3 (1353.42 pg/mL, p=0.000) and day 7 (1565.00 pg/mL, p=0.000), while IFN-gamma. levels were significantly reduced across treatment groups, with the lowest levels in the 20% extract group (p=0.001). These findings indicate that pomegranate extract cream enhances wound healing by upregulating FGF and downregulating IFN-gamma expression, with the 20% concentration showing the most effective response, comparable to Bioplacenton.
