Section two the evaluation of biocompatibility of the acellular dermal matrix by the method of cell culture. the new born rat ' s epdermic cells were cultured with the acellular dermal matrix together as experiment group, while the epdermic cell were cultured simply as control. 24 hours later, under the invert microscope, the epidermic cells anchored well and transparent flat cells were observed in both groups. 7 days later, both cultured cells were taked out and fixed in 95 % ethanol, stained with hematoxylin and were observed under light microscope. many cleaved cells were observed in both groups. during cell culture, no pathogenic microganism was observed. so we considered the acellular dermal matrix was aseptic and had good biocompatibility. section three subdermal implantation of the acellular dermal matrix. 24 rats were used in the experiments. a piece of acellular dermal matrix ( 1. 5 x 1. 5cm2 ) was implanted beneath the dorsum skin flaps of each rat, 1 week, 2 weeks, 3 weeks and 4 weeks after implantation, 6 pieces of acellular dermal matrix were harvested and the size of implanted acellular dermal matrix were measured, the sections were used for he staining and observed under light microscope. the result were as folio wing : 1 - 2 weeks after implantation, the acellular dermal matrix began to adhere to the tissue around and turned red gradually ; 3 - 4weeks after implantation, the acellular dermal matrix adhered closely to the tissue around and could be recognized easily, 1 - 3 weeks after implantation, the size of implanted acellular dermal matrix had no statistical difference ( p > 0. 05 ). 4 weeks after implantation implanted acellular dermal matrix contracted ( p < 0. 05 ). under light microscope, l - 2weeks after implantation, the fibroblast cells infiltrated the acellular dermal matrix and a small amount endothelial cells of vessel and lympho - histiocytic cells infiltrated the acellular dermal matrix. 3 - 4 weeks after implantation, infiltrating blood vessels were evident. so we think that the acellular dermal matrix had low immunological reactions and could induce the infiltration of fibroblast macrophage cell and the endothelial cells of vessel

The highest vt and p valt in true leaf were accompanied two hybridizable polypeptides of aox protein, 35kd and 38kd respectively. the next was cotyledon vt and p valt with only one 38kd hybridizable polypeptide of aox protein. hypocotyl vt and p valt were the lowest and its immunobloting band was similar to that of cotyledon, but the expressive amount of 38kd protein was less than that of cotyledon
