[Preliminary studies on process and ultramicro-pulverization on pharmacodynamics of Leech]
1Shandong University of Trditional Chinese Medicine, Jinan 250014, Shandong, China.
Objective:
To compare pharmacodynamics of decoction and powder of Leech; To identify effect of pharmacodynamics of Leech with new methods of process and ultrmicro-pulverization.
Method:
The size of ultramicor-powder of Leech and new method processed Leech is determined by BT-1500 size distributive instrument. It is compared that the pharmacodynamics of Leech decoction and powder as well as ultramicro-powder with new method processed of 1/2 decoction dose by anticoagulation and antithrombus action of mice. The safety of different samples is identified.
Result:
The pharmacodynamics of samples is as ultramicro-powder of Leech with new method processed > ultrmicro-powder of Leech > powder of Leech > decoction of Leech.
Conclusion:
The ultramicro-powder of Leech with new method processed has better pharmacodynamic effect and the smell of Leech is improved.
