Evaluation of the effects of bitter yam tuber supplementation on serum parameters used to assess hepatotoxicity and nephrotoxicity in transgenic mice
Journal Title: Journal of BioScience and Biotechnology - Year 2014, Vol 3, Issue 2
Abstract
The Jamaican bitter yam (Dioscorea polygonoides) (ITIS) is known to possess potent antidiabetic and hypocholesterolemic properties and can therefore be exploited for associated nutraceutical/pharmaceutical purposes. It however possesses bioactive compounds known to promote organ damage when ingested in excess. This study investigates the effects of bitter yam consumption at a concentration of 5% on liver and kidney damage/function parameters. Normocholesterolemic mice fed bitter yam supplemented diets experienced significant increases in serum aspartate aminotransferase activity and bilirubin, magnesium and phosphorus concentrations. Significant increases were also observed in serum aspartate aminotransferase activity and blood urea nitrogen concentration of the genetically modified hypercholesterolemic mice fed supplemented diets. These results suggest mild kidney damage in both mice species and a significant increase in the rate of erythrocyte haemolysis in the normocholesterolemic mice.
