Effect of Malus sylvestris Extract on Histopathological Features of Hypercholesterolemic Wistar Rat (Rattus norvegicus) Fatty Liver

Objective: To evaluate the effect of Malus sylvestris extract on improving the degree of steatosis and portalinflammation histopathological features of hypercholesterolemic Rattus norvegicus strain wistar. Method:Forty-two male rats were divided into 6 groups randomly. Hypercholesterolemic fatty liver induced bygiving high-fat diet (HFD) for 46 days on groups 1 to 5, while group 6 given standard diet with the sameamount of time. Simvastatin was administered in group 2 at a dose of 0.36 mg/day. Groups 3, 4, and 5 weregiven Malus sylvestris extract (MSE) as a treatment at doses of 90 mg/day, 180 mg/day, and 360 mg/day insequential order. Simvastatin and MSE were administered for 14 days, from day 33 to 46. On day 47, all ratswere sacrificed and the liver was removed for histopathological slides preparation with hematoxylin-eosin(HE) staining. Histopathological results were analyzed using Kruskal Wallis test followed by Mann Whitneytest. Result: Histopathological analysis showed that Malus sylvestris extract improved steatosis and portalinflammation features compared to HFD-fed rats in group 1 (p
