BACKGROUND: Pleurotus ferulae is an edible mushroom has been widely used for nutritional and medicinal purposes. Irrespective of the medicinal importance or therapeutic potentials of P. ferulae, there have not been studies on antihyperlipidemic properties. Therefore, the present study investigates the effects of dietary P. ferulae fruiting bodies on plasma and feces biochemical and on the liver histological status in hypercholesterolemic rats.METHODS: Six weeks old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. Then biochemical and histological examinations were performed. RESULTS: Feeding of a diet containing 5% P. ferulae fruiting bodies to hypercholesterolemic rat reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and LDL/high-density lipoprotein ratio by 30.02, 49.31, 71.15, 30.23, 21.93, and 65.31%, respectively. Mushroom also significantly reduced body weight in hypercholesterolemic rats. However, it had no adverse effects on plasma albumin, total bilirubin, direct bilirubin, creatinin, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, and enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that P. ferulae significantly reduced plasma β and pre-β-lipoprotein, while increased the α-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red O staining showed normal findings for mushroom-fed hypercholesterolemic rats. CONCLUSIONS: The present study suggests that 5% P. ferulae diet supplement provides health benefits, at least partially, by acting on the atherogenic lipid profile in hypercholesterolemic rats.
