Abstract

Objectives

The objective of this research is to develop new animal-experimental model for Sasang Constitutional Medicine, especially for partial Taeyangin(one of four constitution which has good pulmonary function and poor hepatic function) by AAP intraperitoneal injection, and to estimate from the viewpoint of obesity and lipid metabolism.

Methods

The C57bl/6J mice was divided into 4 groups; Normal group, AAP group, High-Fat-Diet(HFD) group, and HFD+AAP group. 200mg AAP was injected intraperitoneally to the AAP group twice a week for six weeks, and HFD group was fed with 60%-High-fat Diet for six weeks. HFD+AAP group got both AAP injection and 60%-High-fat Diet at the same time for the same period. In this period, We measured the weight and Food Efficiency Ratio(FER, %) once a week. After six weeks, We conducted the blood chemical test from the groups, and extracted the fat tissue to measure weight.

Results & conclusion

In the liver function test, two AAP groups had higher AST and ALP, and normal LDH. The blood level of creatinine from all groups were normal. The rate in weight was lesser by 7.8% in HFD+AAP group, and had lesser FER than HFD group. Also They had lesser Total cholesterol and LDL cholesterol, and had more HDL cholesterol than HFD group. HFD+AAP group hadmore glucose in serum and lesser Insulin-like Growth Factor 1(IGF-1) than HFD group.
