The effects of caffeinated and non-caffeinated paracetamol administration, with or without vitamins A and E supplementation on the protein and enzyme levels in Wistar albino rats were investigated using cafeinated paracetamol and paracetamol as caffeinated and non-caffeinated paracetamol respectively, and water soluble acetic acid derivatives of vitamins A and E. Serum AST, ALT and ALP levels (u/l) significantly increased [P < 0.05] following paracetamol administration. Caffeination as well as administration of vitamins A and E caused significant decreases[P < 0.05] in AST and ALP levels in all test groups when co-administered with paracetamol and in ALT level except in the cafeinated paracetamol + Vitamin E group in which ALT and ALP level except in the cafeinated paracetamol + vitamin E group in which ALT and ALP levels significantly increased [P < 0.05]. Total serum protein level (g/100ml) significantly increased following caffeination as well as during co-administration of cafeinated paracetamol and Vitamin E; and significantly decreased during co-administration of paracetamol and vitamin A. Paracetamol administration without caffeination or supplementation with vitamin A and E can therefore cause increases in serum liver enzymes that is suggestive of liver necrosis which can be ameliorated to varying degrees by caffeine, vitamin A and E. 相似文献

Effect of caffeine-coconut products interactions on induction of drug-metabolizing enzyme in wistar albino rats was studied. Twenty rats were randomly divided into four groups: The control group (1) received via oral route a placebo (4.0ml of distilled water). Groups 2 to 4 were treated for a 14-day period with 50 mg/kg body weight of caffeine, 50 mg/kg body weight of caffeine and 50 mg/kg body weight of coconut water, and 50 mg/kg body weight of caffeine and 50 mg/kg body weight of coconut milk in 4.0ml of the vehicle via gastric intubation respectively. One day after the final exposure, the animals were anaestheticized by inhalation of an overdose of chloroform. The blood of each rat was collected by cardiac puncture while the liver of each rat was harvested and processed to examine several biochemical parameters, i.e., total protein and RNA levels, protein/RNA ratios, and activities of alanine and aspartate amino transferase (ALT and AST, respectively). The results showed that while ingestion of coconut milk and coconut water increased the values of protein and protein/RNA ratios, it decreased alanine and aspartate amino transferase (ALT and AST) activities. These effects, in turn, enhanced the induction of the metabolizing enzymes and a resultant faster clearance and elimination of the caffeine from the body, there by reducing the toxic effect on the liver. 相似文献
