Figure 4: Histopathological changes in rat heart. (a) Vehicle-treated group showing normal myocardial fibers; (b) Bromocriptine group showed normal histological structure of rat heart; (c) Fructose-treated group revealed focal myonecrosis and lymphocytic infiltration (myocarditis); (d) Fructose + bromocriptine-treated rat heart showing better architecture indicating protection from fructose-induced changes; (e) Fructose + bromocriptine + metformin indicated good architecture of myocardial fibers; (f) Fructose + bromocriptine + pioglitazone showed improvement in cardiac architecture; (g) Fructose + bromocriptine + insulin showed cardiac protection
