Abstract
The effects of dichloromethane (CH$_2$C1$_2$), ethylacetate (EtOAc) or water ($H_2O$) fraction of Korean cabbage kimhi on accumulation of lipids in the heart, kidney and lung of rabbit fed 1% cholesterol diet for 16 weeks were studied. The amount of kimhi fraction added to the 100 g of diet was 8.3 mg of CHaC12.5.6 W of EtOAc, and 221.9 mg of $H_2O$, which are equivalent to 5% of freeze-dried kimhi added to the diet. Each group had 6 rabbits and rabbit was housed individually. Cholesterol and triglyceride concentrations of three organs were noticeably decreased due to these solvent fractions of kimhi but for phospholipid and total lipids, only CH$_2$C1$_2$ fraction group showed decreasing effects. In the heart, compared to the control, cholesterol concentrations for CE$_2$C1$_2$, EtOAc, and H2O fraction group were decreased by 42 (P<0.05),21 (P<0.05), and 8%, respectively, and triglyceride for these groups were decreased by 29 (p<0.05),4, and 11%, respectively. In kidney, cholesterol concentration for CH$_2$C1$_2$, EtOAc, and H2O fraction group were decreased by 23, 12, and 11%, respectively (p<0.05) and triglyceride concentration for CH$_2$Cl$_2$ and H2O fraction groups were significantly decreased by 51 and 21%, respectively (p<0.05). In lung, cholesterol concentrations for CItCIB, EtOAc, and H2O fraction groups were decreased by 37,20, and 22%, respectively (p<0.05) and triglyceride concentration of these groups were significantly decreased by 39, 28, and 28%, respectively (p<0.05). And phospholipid and total lipid of CH$_2$CI$_2$ fraction group were significantly decreased by 33 and 34% respectively (p<0.05). Among three organs the cholesterol content of lung was the highest followed kidney and heart. For triglyceride, heart, kidney and lung is in the order of showing the highest concentration. The phospholipid concentration was not significantly different among three organs. According to these results, we may conclude that CH$_2$C1$_2$, fraction of kimhi might have the most active component, which decreases cholesterol, triglyceride, phospholipid and total lipids concentrations in heart, kidney, and lung of rabbit fed high cholesterol diet.
