There were dose dependent decrease in enzymes activities (ALT, AST, GGT and ALKPHOS) in Sugar and gari fed albino rats compared with their controls. There was no significant difference in the enzymes activities between the sugar and gari fed rats .The study showed that 20%sugar and 20% gari reduced enzyme induction caused in rats fed crude oil contaminated diet through reducing cAMP concentrations. The reduction was not significant between the sugar and gari fed . Therefore sugar and gari diets can repress enzymes induction through the process of glucose effect. Key words: Glucose Effect % Sugar % Gari % Crude Oil INTRODUCTION Goldberg [2] showed that glucose feeding causes in both Exposure of humans and animal to crude oil, which is include inhibition of induction of several enzymes, increasing in terms of the environmental levels and stimulation of others and blockage of most effects of application to body, may be toxic. Crude oil is used in glucocorticods while Bostford and Harman [3] studied the folkloric medicine in the Niger-delta area of Nigeria for the reduction of gene expression by glucose (catabolite treatment of various ailments including stomach up-set, repression) in various microorganisms. The sugar cane is wound and burns [1]. In several organs, mainly heart and one of the most important sucrose sources, containing liver, cell damage is followed by increased levels of a until 20% wt sucrose [4]. The sucrose is a natural number of cytoplasmic enzymes in the blood, a sweetener, traditionally, used in human nourishment due phenomenon that provides the basis for clinical diagnosis to its pleasant taste, nutritious value and low cost of heart and liver diseases e.g. liver enzymes are usually production. Sucrose hydrolysis produces a fructose and raised in acute hepatotoxicity but tend to decrease with glucose equimolar mixture named inverted sugar, which prolonged intoxication due to damage to the liver cells. has higher edulcorant power. Feeding varieties of carbohydrates (Glucose, sucrose Cassava is a staple food in human diets in over 80 and fructose) to mammals and bacteria result in blocking countries [5]. Gari a starchy food prepared from cassava the induction of many enzyme systems. Melvin and (Manihot utilisima) tubers is one of the most popular man and microorganism profound changes in metabolism
