Nine wethers of Inner Mongolian White Cashmere(IMWC) goats(25-30 kg) with the same father,fitted with permanent cannulas at the proximal duodenum,and with two sides temporary carotid venous catheters were used to investigate the effect of absorbable amino acid pattern in the small intestine,i.

Two tensile tests of sewing the incision concrescence rat skin by the absorbable suture;

Absorbable Screw in the Treatment of Joint Fracture;

They are more promising absorbable implantable materials for medicine application, and have been put into the research and development on surgical suture, membrane for the prevention of postsugical adhesion and internal fixation of bone fracture et al.

The organic and elemental carbon in absorbable particle have been decreasing greatly which improve the atmosphere environment quality.

In this study, the poly-D,L-lactic (PDLLA) absorbable rods were comfirmed to have good biocompatibility by embed experiment, and the degradation experiment in vitro and in vivo showed good mechanical features and total in vivo absorption of the rods, indicating that the rods meet the demands to be a biodegradable internal fixation material.
