中文摘要 | 飲食中含較不飽和之油脂常促使血漿脂質降低,但最近的一些研究卻發現會增加肝臟中脂質的堆積。本實驗旨在探討大白鼠攝取高膽固醇與高黃豆油或魚油條件下,若添加磷脂質是否能影響血漿和肝臟中之脂質濃度?此外,另添加果膠時,是否更能降低血漿脂質或肝脂肪?實驗以雄性Wistar大白鼠為實驗動物分別餵以添加磷脂質或不添加磷脂質之黃豆油飼料或魚油飼料飼養8週。 實驗結果顯示,磷脂質不論是添加在黃豆油或魚油組,皆能明顯降低大白鼠肝臟總脂質與膽固醇,而在魚油組中亦能降低肝臟三酸甘油酯。磷脂質在不同油脂下對血漿脂質影響有不同結果,在魚油組中磷脂質只能降低血漿總脂質,但在黃豆油組中則能降低血漿三酸甘油酯的濃度。在飼料中添加果膠則更能明顯降低血漿和肝臟脂質。 |
英文摘要 | Distary polyunsaturated oils can decrease plasma lipids but induce severe fat accumulation in liver. The study was designed to investigated different effects on serum and liver lipids in rats when phospholipids were added in high cholesterol and high soy oil or fish oil diet. Moreover, the effect of adding pectin in a diet was also studied. Male Wistar rats fed diet with or without phospholipids and with soybean oil or fish oil for 8 weeks were employed in the study. The results showed that the concentrations of total lipids and cholesterol were significantly lowered in livers of rats fed with phospholipids. Among phospholipids-fed rats, the fish oil-diet group had lower levels of liver triacylglycerol than the soybean oil-diet group. The phospholipids in fish oil diet lowered the plasma total lipids, whereas in soybean oil diet they reduced the plasma triacylglycerol. Adding pectin to a diet decreased plasma and liver lipids significantly. |
