Abstract
Biochemical changes in the serum and liver of albino rats chronically exposed to rats administered 5gk-1 , 7.5gk-1 and 15gk-1 of gasoline , kerosine and crude petroleum(bonny light) respectively were studied. The petroleum samples were administered intraperitoneally and the biochemical changes in the rat serum and the liver wree monitored over a three monthduration:Asparate amino transferase (AST) Alanine amino transferas (ALT) and Alkaline Phosphate (ALP) all showed dose- dependent increase in levels from zero month to 3rd month, gasoline from 19.0 ± 2.8 of control to 69.0 ±12.8 third month kerosine 19.0 ±2.8 control to 58±5.0 third month and crude Petroleum 19.0±2.8 control to 33.2 ± 1.3 at the third month. Alanine amino transferase increase from 12.0 ± 1.1 of control to 62.0 ± 6.0 at the third month with gasoline, also from 12+ 1.1 of control to 29.7 + 5.6 in the third month with kerosene and from 12.0 ± 1.1 of control to 27. ± 3.1 at the third month with crude petroleum. Furthermore, the alkaline phosphatase increase from 62.1 ± 3.0 μ/l control to 161.0 ± 2.0 at the third month for gasoline, kerosene from 62.1 ± 3.0 of control to 123.6 ± 12.6μ/l at the third month, with crude petroleum (bonny light) increasing from 62.1 ± 3.0 μ/l of control to 90.5± 6.3 μ/l at third month. Glutathione transferase (GST) was marginally increase in gasoline treated rats from 13.0 ± 0.8 μ/l of control to 17.0 ± 1.0 u/l however, greater elevation in level of the enzyme was obtained in kerosene treated rats from 13.0 ± 0.8 μ/l of control to 25.2 ± 2.0 μ/l at the third month. Finally the reducedglutathione (GSH) seemed to be depleted from 0.56 ± 0.1 mM of control to 0.43 ± 0.1 at the third month with gasoline, 0.30 ± 0.1 mM at the third month with kerosene and 0.41 ± 0.1 mM at the third month with crude petroleum (bonny light). In conclusion the petroleum sample caused biochemical changes in the serum andliver of the rats. @ JASEM
