Degradation test in vitro was carried out in phosphate buffer solution (0.1M, pH7. 4) at 37 ℃. The buffer solution was changed daily. Degradation test in vivo was implanted the sample to subdermal in adult ICH rat in the scapular area lateral to the dorsal midline. At suitable time the samples were recovered. Molecular weight changes in surface layer and bulk of polymer sample were measured by GPC and weight loss was determined gravimetrically. It was found that the degradation behavior can be regulated by changing the composition of copolymers. The critical compositions from surface to bulk degradation behavior for PGCA, PLCA, PLMCA, PLDCA systems were 15-20, 20-30, 30- 40, 40 of mol percent GA or LA unit in copolymers, respectively. The degradation behavior of PGCA, PLCA, PLMCA, PLDCA systems were compared and analysed. Some factors influencing the degradation character, such as copolymer composition, hydrophobicity, crystallinity and enzyme affect etc. played important role.

The proliferative capacity of LEC from human had directly relevance to the age of donor(r=-0.996).Conclusions The formation of lens-like spherules is characteristics of LEC lines in the cultured cells.Under identical conditions,the proliferative rate of LEC from bovine and rabbit is fast than that of LEC from human,but dedifferentiation of LEC from bovine and rabbit is easier than that of LEC from human;LEC from the three species exhibit similar limited growth potential.The proliferative rate of LEC from human has a inversely proportion with age.
