[Difference of hypaconitine concentration in serum between cold-deficiency and normal mice].

OBJECTIVE
To investigate the difference of hypaconitine concentration in serum between normal and cold-deficiency mice after administration of aconite decoction. To analyze how the toxic dose of aconite decoction correlate to the metabolic environment.


METHOD
Prepared cold-deficiency mice model, treated normal and cold-deficiency mice with aconite decoction for 14 days continuously, and then detected hypaconitine concentration in serum by HPLC along with survival ratio of mice on the first, seventh and fourteenth day.


RESULT
After administration of aconite decoction for 14 days, the hypaconitine concentration in serum of cold-deficiency mice is close to that in normal mice. It showed aconite decoction has the ability of regulating metabolism environment, the hypaconitine concentration in serum of normal mice was higher on the seventh and fourteenth day than that on first day. It showed that aconite decoction can disturb metabolism environment of normal mice. It was also been observed that the range of variation of hypaconitine concentration in cold-deficiency mice was minor than that in normal mice during the fourteen days' administration.


CONCLUSION
The difference of serum concentration in normal and cold-deficiency mice showed that there were different metabolic environments in two mice models, and the metabolic environment changed during administration. These results showed that the different toxic doses of aconite decoction were partially due to the different metabolic environments.
