An Experimental Evaluation of the Physiological, Molecular, and Histological Effects of Pyridoxine on the Cardiovascular System in Ovariectomized Rabbits

This work looks into OVX rabbits that are representative of menopausal levels of estrogen deficiency to determine whether pyridoxine supplementation can afford cardiac protection.Ovarian hormones, particularly estrogen, have been proven to mediate numerous cardiovascular risk factors such as endothelial dysfunction, oxidative stress, and insulin resistance in postmenopausal women. In the present study, PY was examined regarding its impact on CVBMS, histopathological variations, and the expression of genes connected with CV function in OVX rabbits. Eighteen healthy female rabbits were divided into three groups: Sham operation, ovariectomy (OVX), and ovariectomy plus pyridoxine (Sigma purchased, 10 mg/ kg/day for 12 weeks). Serological assessment confirmed the effectiveness of pyridoxine supplementation to modulate upregulated cTnT and Lcn-2 in decreased myocardial injury and inflammation.Moreover, the OVX + Pyridoxine group had a marked enhancement in the activity of nitric oxide synthase (NOS), implying better endothelial integrity. Using various histopathologic features of myocardial tissue, it has been proven that pyridoxine administered to the rats reduced the extent of structural changes, such as fibrosis and inflammation, and enhanced the tissue organization.Molecular study of gene expression profile established thatNos3 gained tremendously in expression in the OVX + Pyridoxine group, raising the possible effect of pyridoxine on endothelial function. věty These outcomes indicate that pyridoxine supplementation can ameliorate cardiovascular dangers triggered by estrogen deficiency by decreasing oxidative stress, enhancing endothelial function, and reversing myocardial structure. From this research, this author has discovered that pyridoxine could be useful for treating postmenopausal cardiovascular disorders.
