This study was undertaken to investigate the effects of mustard leaf diet on the lipid metabolism under chronic alcohol administration. Sprague-Dawley male rats were fed either AIN-76 diet(control), control with ethanol, AIN-76 diet plus 5% mustard leaf(mustard leaf), or mustard leaf with ethanol lot 30 days. On the 21st day, all of the rats were given an oral dose of ethanol and blood-ethanol concentration were monitored for the next 5 hours. Lipid and enzyme determinations in serum and liver were carried out after 30 days. The results obtained were summarized as following: 1) Supplementing 5% of mustard leaf did not recover the body weight loss due to chronic alcohol administration. 2) There were no significant differences in blood ethanol concentrations among the experimental groups. 3) Mustard leaf diet decreased the plasma total cholesterol, triglyceride levels increased due to the chronic alcohol administration, but not HDL-, LDL-cholesterol, and liver lipids. 4) Mustard leaf diet decreased ${gamma}$ -GTP level increased by chronic alcohol administration. Overall, these data suggest that mustard lear can have a recovery function, which was not via ethanol metabolism on the symptoms of alcohol related diseases.(Korean J Human Ecology 1(1) : 94~102, 1998)
