Application of six-bar mechanism in the design of knee joint prosthesis / 中国组织工程研究

This paper validated the centrode of six-bar mechanism was similar to circle center curve for different bending radius of the lemur, and introduced the gait analysis of knee joint of six-bar mechanism in normal movement t oprovide theoretical design foundation for developing a new knee joint.

Controlled release of interferon tau from chitosan-alginate microcapsules / 中国海洋药物

Objective The microcapsules were prepared by using chitosan and sodium alginate as wall materials,and the controlled-release microcapsulas of interferon tau were hoped to be develop an oral interferon preparation.Methods The microcapsules were prepared by using syringe hand-made drop.In the process of dropping,speed and distance were the major factors which influence the form of microcapsules.Results Chitosanalginate microcapsules which was prepared simple and fast had high encapsulation rate and extended-release effect in intestine.Conclusion Chitosan-alginate microcapsules have the potential to be used to prepare interferon tau and other protein medicines.
