To investigate the effects of the supplementation of carnitine and/or ${\gamma}$ -aminobutric acid (GABA), Sprague-Dawley male rats were orally treated with either an AIN-76 diet (control), a control diet plus ethanol (CE, 4 g ethanol/kg bw), CE plus L-carnitine (CEC, 0.5 g/kg bw), CE plus GABA (CEG, 0.5 g/kg bw), or CE plus L-carnitine plus GABA (CECG, 0.25 g/kg bw each) for 6 weeks. Serum triglyceride levels were increased in the CE group and were decreased significantly in the CEC, CEG and CECG groups. HDL-cholesterol was increased and LDL-cholesterol was decreased in the CEG and CECG groups compared with the CE group. Serum GOT and GPT levels increased by the chronic ethanol administration were decreased in the CEC group. In addition, we have evaluated the mRNA levels of carnitine palmitoyltransferase-I in those groups. Supplementation of carnitine/GABA had some recovery effects on the liver CPT-I mRNA levels which decreased by chronic ethanol administration. These results may suggest that supplementations of either L-carnitine or GABA aye effective on the recovery of chronic ethanol-related symptoms, but no combined effects were shown.
