title: Potential protective effects of Nigella sativa and Allium sativum against fructose-induced metabolic syndrome in rats.
abstract: Among famous medicinal plants with known antioxidant activity; black seed (Nigella sativa, NS) and garlic (Allium sativum) which have been used in traditional medicine. In recent years, rates of metabolic syndrome (MS) have been increasing globally. The present work was designed to study the potential protective effects of black seed and raw garlic homogenate against fructose-induced MS in rats and to assess the benefits gained from their combination. Fifty male albino Wistar rats were divided into 5 groups. A control group was allowed to feed on normal chow and drink tap water. MS group was fed the same diet plus 10% fructose in drinking water. Treated groups received NS or garlic either alone or in combination as oral supplements along with high fructose diet for 8 weeks. Results revealed that body weight, liver weight, fasting blood glucose, serum triglycerides (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C) levels were significantly increased while high density lipoprotein cholesterol (HDL-C) and the activities of Lactate dehydrogenase (LDH), glucose -6-phosphate dehydrogenase (G-6-PHD) and catalase in liver tissues were significantly decreased in MS group compared to the control group. Administration of NS or garlic either alone or in combination significantly ameliorated all the above-mentioned altered parameters. Treatment with both NS and garlic showed the utmost reduction in serum LDL-C and TG levels and could restore the activities of the studied enzymes in liver nearly to normal values. It was concluded that both NS and garlic were effective in attenuating multiple abnormalities of MS. Combination of these medicinal plants may have additional effectiveness in reducing serum TC, LDL-C and increasing HDL-C levels which could be a step in the prevention and management of MS.
