Nephrotoxicological Effect of Water Soluble Fraction of Bonny Light Crude Oil in Wistar Albino Rats . International Journal of Biochemistry Research & Review. 2019 Dec; 28(4): 1-92231-086Xhttp://imsear.searo.who.int/handle/123456789/200759This study evaluated the Nephrotoxic effect of water soluble fraction (WSF) of Bonny Light Crude Oil (BLCO). After preparation of the WSFand a range finding test, the Wistaralbino rats were administered three concentrations (25%, 50% and 100%) of WSF of BLCO for 30 and 60days. Data from the study showed that Urea concentration increased significantly (p≤0.05) with increasing dose of BLCO ranging from 14.71mg/dl in the control to 35.28mg/dl in the 100% group after 30days and 14.28mg/dl in the control to 41.08mg/dl in the 100% group after 60days, Creatinine concentration increased significantly (p≤0.05) from 0.22mg/dl in the control to 0.82mg/dl in the 100% group after 60 days administration while electrolyte (Na, K, Cl) concentration increased significantly (p≤0.05) with increasing dose of BLCO after 60days administration. Histopathological examination of the kidney was characterized by partial partitioning of the glomerular tufts, obliteration of the Bowman’s capsule and distortion of the renal tubules. The findings in this research suggest that WSF of BLCO induced nephrotoxicity.Water soluble fractionbonny light crude oilureacreatininenephrotoxicityJournal ArticleIndiaInstitute of Natural Resources Environment and Sustainable Development, University of Port Harcourt, Nigeria.Centre for Petroleum Geoscience, University of Port Harcourt, Nigeria.World Bank Africa Centre of Excellence for Public Health and Toxicological Research, University of Port Harcourt, Nigeria
