[Fabrication and characteristics of oriental poly (lactic-co-glycolic acid) scaffold: a preliminary study].

Objective: To explore the method of fabricating oriental scaffolds and investigate the biocompatibility of the scaffolds as well as cells distribution within the scaffolds in vitro.

Methods: The oriental poly (lactic-co-glycolic acid) (PLGA) scaffolds were fabricated with modified emulsion-phase separation method. The scaffolds were treated with plasma and then anchored with collagen I.

[Drug release and biocompatibility of cyclosporine A drug delivery system implanting into the anterior chamber].

Objective: To study the drug concentration in the aqueous humor and the biocompatibility of cyclosporine A drug delivery system (CsA DDS) implanting in the anterior chamber.

Methods: There were four different types of CsA DDS which had different biodegradable polymers as the vector or had different ratio between CsA and the vector. Thirty-six New Zealand rabbits were randomly divided into 4 groups to receive the 4 different types of CsA DDS.
