1. 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
