Abstract
Influence of excessive intake of ascorbic acid (AA) on alcohol induced hyperlipidemia was investigated. In the present study four groups of male guinea pigs were maintained for 30 days as follows: (1) Control group (1 mg AA/100 g body wt). (2) Ethanol group (I mg AA + 9 g ethanol/100 g body wt). (3) AA group (25 mg AA/100 g body wt). (4) AA + Ethanol group (25 mg AA/100 g body wt + 9 g ethanol 100 g body wt). It was shown that tissue ascorbic acid concentration increased with the intake of mega dose of AA. Alcohol administration depleted tissue ascorbic acid content. But coadministration of AA and alcohol enhanced AA levels in comparison with the ethanol group. Alcohol induced hyperlipidemia was reduced in almost all the tissues by the intake of ascorbic acid. This was observed to be due to increased hepatic catabolism of cholesterol to bile acids. However cholesterogenesis was enhanced as evidenced by the increased HMG CoA activity. Thus the results indicate that the mega dose of AA ingestion is beneficial in reducing alcohol induced hyperlipidemia and AA deficiency.
