LMCPs(1.0 g/kg body weight) in 15% ethanol(10 mL/kg body weight) were given to Wister rats by intragastric gavage. The assay of blood ethanol was conducted by using the enzyme based assay kit. The amino acid analysis was made with an amino acid analyzer. The data of the animal experiments showed that LMCPs could accelerate the metabolism of alcohol in rats. In the control group, the blood ethanol concentration reached the maximum level of (827.0±77.3) mg/L after ethanol loading for 30 min, then gradually decreased. In contrast, the blood ethanol concentration only reached (527.25±47.0) mg/L after 30 min in the group of LMCPs taken. These results indicate that LMCPs could decrease ethanol concentration in blood rapidly.展开更多
