Research Abstract

This research was done using the new composition preparations emulsified with PG (phosphatide compounded by epikuron200 and glycerol to phospholipase DM which is soy lecithin) which mixed MCT and LC in an equivalent amount of 1 to 1 as neutral fat 10%.Using four weeks of Wistar system age maleness rat, the self-sustaining intravenous dosage containing a new composition PG emulsification MCT/LCT agent was performed, and measurement of the neutral fat, phosphatide, HDL cholesterol, AST, ALT, direct, and indirect bilirubin value was performed. As a result, an impaired liver function was prominent at the medication speed of 1.2g/kg/hr and 1.8g/kg/hr, and it turned out that optimal speed is 0.6g/kg/hr.
