[Study on preparation and quality standard of Xueshuantong Drop Pills].

Objective: To optimize the best technical parameters and establish the quality standard for Xueshuantong Drop Pills.

Methods: Using moulding probability of drop pill as the evaluation to choose the best dropping condition. Using parallel experimentation for the choice of proportion of drug and matrix, and refrigerant; HPLC method was employed on ODS column which was used with a mobile phase of acetontrile-water, 0 min 20% A, 14 min 40% A, 15 min 60% A, 16 min 20% A.

[Preparation of new lipid-hydroxyapatite-DNA complex and gene transfection reseach in eukaryotic cell].

This work was directed at obtaining a better gene carrier to improve the effects of gene delivery. Neutral liposomes made from cholesterol, lecithin and DOPE by reverse evaporation technique were used for encapsulating DNA-HAP complex which was made from DNA and optimized HAP. The sizes of complexes and the efficiency of encapsulation were detected.
