Rats were fasted for 8 hours and then fed 3 ml of 25% (v/v) ethanol per 100g body weight and subsequently sacrificed 18 hours
later. The levels of triacylglycerols and total cholesterol were significantly raised in serum and liver of alcohol fed rats.
However, when rats were fed on aqucous extract of onions (300 mg per 100g body weight) with 25% ethanol, no rise in serum
and liver lipids was observed. Alcohol fed to the fats with or without onion extract had no effect on serum, AST, ALT and
alkaline phosphatase levels. The increase in serum urea in ethanol-fed rats was not altered in rats fed a mixture of alcohol
and onion extracts. Values of liver MDA was lower in rats fed ethanol with or without onion extract compared to controls.
Onion extract seemed to show a hypolipidemic effect in alcohol fed rats. 相似文献

Risk-taking by biology students as they attempt to explain observed biological events was investigated. The dependent variable, risk-taking as measured by the Extremity-Confidence of Hypothesis Test and the Risk-Taking Verbal Observation Scale, was analyzed within 2 × 2 and 2 × 3 factorial designs. The independent variables consisted of two levels of achievement motivation and status of information, and three levels of group arrangement for discussion. The results indicate that verbal risk-taking is influenced by differential knowledge of the information and the composition of a discussion group based on the members' measured achievement motivation. No differences were noted in the comparison groups on risk-taking as measured by the Extremity-Confidence of Hypothesis Test. A significant, but low, positive correlation was found to exist between IQ and risk-taking in verbal discourse by individuals. Based on the results of this study, the suggestion that risk-taking is a multidimensional trait is supported, and the magnitude of its expression may be influenced by differential treatments. 相似文献
