the supplemental effect of vitamin-d3 and omega-3 on induced endometriosis in rat model to investigate the inflammatory response

Background & objective: the endometriosis treatment was critical due to complications associated with current drug delivery system. the present study was conducted with aim to compare the curative effect of vitamin d3 (vtd3) and omega–3 (og3) with diphereline during the treatment of endometriosis.materials & methods: in this study, endometriosis was induced in different groups containing 60 adult female rats. the rat model was categorized into 6 groups untreated and treated (olive oil (solvent), vtd3 (42 mcg/kg/day), og3 (450 mg/kg/day), vtd3+og3, diphereline (3 mg/kg/day)). the suspension containing combination of diphereline and supplements was injected and treated for 4 weeks to analyze the effect of supplements. the interleukin -6 (il-6) and tumor necrosis factor – alpha (tnfα) inflammatory responses were measured from the serum samples while endometrial implants was dissected and histopathological investigation was done.results: at the end of four weeks, pathologic score decreased significantly with simultaneous measurement of inflammation score of endometriotic lesion, size of implant area, il-6, tnfα response and compared with untreated female rat. no significant different was observed in groups undergoing treatment of vtd3, og3 and diphereline. the combined effect of vtd3+og3 has similar responses with diphereline treated endometrial implants. conclusion: treatment of vtd3 deficiency and making a change in dietary habits of high-risk population for endometriosis from adolescence may also play a preventative role in adulthood.
