Abstract

This study was investigated the mechanism of action of n-6/n-3 fatty acid ratio on the metabolic partitioning of blood glycerolipids by in vivo monitoring technique in hyperlipidemic animal model rats. The ratio of cholesteryl 14C-oleate metabolized in the liver of total glycerolipids was lower in the order of n-6/n-3 ratios of 4:1, 15:1, 30:1 and control group (p<0.05). The secretion amount of phospholipid was higher in the order of n-6/n-3 ratio 4:1, 15:1, 30:1 than the control (p<0.05). The secretion amount of triglyceride was lower in especially 4:1, in order of n-6/n-3 4:1, 15:1 and 30:1 compared with the control. The ratio of phospholipid partitioning to total glycerolipid was high in orfer of n-6/n-3 ratio 4:1, 15:1, 30:1 and control (p<0.05). The triacylglycerol partitioning (%) via liver was higher 72.97, 75.93, 78.12% in n-6/n-3 4;1, 15:1, 30:1, respectively than the control of 82.25%, according to increased n-6/n-3 (p<0.05). The phospholipid partitioning (%) was lower 25.15, 18.87, 18.15% in n-6/n-3 4;1, 15:1, 30:1, respectively, compared to control 11.04%, according to increased n-6/n-3 (p<0.05).

본 연구는 고지혈증 모델동물 랫드에서 n-6/n-3가 서로 다른 식이를 급여하였을 때 혈액지질의 대사적 분할에 미치는 작용 메카니즘을 생체 모니터링 기법으로 구명하였다. 총 glycerolipids의 간에서 대사된 cholesteryl $^{14}C$-oleate 비율은 n-6/n-3 비율 4:1, 15:1, 30:1, 대조군 순서로 낮았다(p<0.05). 인지질 분비량은 대조군과 비교할 때 n-6/n-3 비율 4:1, 15:1, 30:1 순서로 높았다(p<0.05). 중성지방 분비량은 대조군과 비교할 때 n-6/n-3 비율 4:1, 15:1, 30:1 순서로 특히, 4:1 처리군에서 낮았다(p<0.05). 총 glycerolipid에 대한 인지질의 분할 비율은 n-6/n-3 비율 4:1, 15:1, 30:1, 대조군 순서로 높았다(p<0.05). 간으로부터 중성지방 분할 비율(%)은 대조군 82.25%와 비교할 때 n-6/n-3 비율 4:1, 15:1, 30:1에서 각각 72.99, 75.93, 78.12%로써 n-6/n-3 비율이 증가할수록 높아졌다(p<0.05). 인지질 분할 비율(%)은 대조군 11.04%와 비교할 때 n-6/n-3 비율 4:1, 15:1, 30:1에서 각 25.15, 18.87, 18.15%로써 n-6/n-3 비율이 증가할수록 낮아졌다(p<0.05).
