Abstract

Effects of dietary fatty acids and vitamin E on antioxidant system were studied in rat liver and serum. Sources of dietary fat (10 wt%) were safflower oil (SO) poor in $\omega$3 fatty acid and mixed oil (MO) with computer-adjusted fatty acid ratios (AA/DHA=1.4, $\omega$6/$\omega$3=6.3, P/M/S=1.0/l.5/1) with (ME) and without (MO) vitamin E (500 mg/kg diet). Rats were fed the three kinds of diet from 3~4 wks prior to the conception. At the age of 3 and 9 wks of the second generation rat, antioxidant vitamins and glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) activities were measured in the liver and serum. The concentrations of $\beta$-carotene were lower in ME than in MO and SO in the liver at the age of 3 wks. It seemed that vitamin E has an inhibitory action on the uptake of $\beta$-carotene or acts as a preferred antioxidant to $\beta$-carotene. The concentrations of lycopene were lower in SO than in MO in the liver at the age of 3 wks. The concentrations of cryptoxanthin showed no significant changes within groups. The activities of GSH-Px tended to increase in ME compared to MO and the ratios of SOD/GSH-Px tended to decrease in ME compared to MO in the liver at the age of 3 weeks. The activities of antioxidant enzyme at the age of 3 weeks and 9 weeks were similar. This suggested that the activity level of antioxidant enzymes reached to the adult level at the age of 3 weeks which is the end point of lactation period.

$\omega$3계 지방산 결핍군인 safflower oil(SO)군, 지방산을 바람직한 비율로 공급한 mixed oil(MO, P/M/S ratio=1.0 : 1.5 : 1, $\omega$6/$\omega$3 ratio=6.3)군 및 비타민 E를 보충시킨(MO+비타민 1500 mg/kg diet, ME군)식이로 임신되기 3~4주전부터 섭취시키고, 이로부터 출생한 제 2세대 쥐의 간과 혈청에서의 항산화비타민과 항산화효소의 활성을 측정하였다. 식이 지방산과 비타민 E의 보충에 따른 항산화비타민 농도의 변화를 보면 생후 3주의 간조직과 생후 9주의 혈청에서 비타민 E를 보충한 ME이 MO군보다 $\beta$-carotene의 농도가 유의적으로 감소(p<0.05)되어 나타났다. Lycopene농도는 생후 3주의 간에서 MO, ME군에 비하여 SO군에서 유의적으로 낮게 나타났으며 (p<0.05), 혈청에서는 생후 3주와 9주 모두 실험군간의 차이를 나타내지 않았으며, cyptoxanthin의 농도는 간과 혈청에서 생후 3주와 9주 모두 유의적인 차이를 나타내지 않았다. 간조직의 SO군과 MO군간의 항산화 효소의 활성은 생후 3주와 9주 모두 유의한 차이를 나타내지 않았다. 비타민 E의 첨가시 생후3주의 간에서 GSH-Px의 활성은 유의적으로(p<0.05) 증가하였고, SOD/GSH-Px의 비율은 식이지방산의 불포화도에 따른 타이는 관찰되지 않았으며, 비타민 E의 첨가시 생후 3주에서 유의적으로 감소되어 나타났다. 생후 9주에서는 이러한 실험군간의 차이가 나타나지 않았는데, 이는 생후 9주가 되면서 식이에 어느 정도 적응된 결과라고 사료된다. 혈청에서의 GSH- Px의 활성은 생후 3주의 경우 불포화도가 높은 식이를 섭취한 SO군에서 MO군보다 유의적으로 높게 나타났다. 이는 SO 식이의 높은 불포화도로 인하여 방어기전으로 항산화효소의 활성이 증가되었을 가능성과 동시에 최근 항산화체계에 관련성이 있다고 연구되고 있는 oleic acid(18:1)의 비율과도 관련이 있을 것으로 보여 여러 항산화계의 균형성과 상호작용 측면에서 종합적인 결과로 해석해야 함을 지적해 주었다.
