The treatment of extensive deep burn wound is mainly by transplantation of razor - thin graft or split - thickness skin autograft in clinic . but the lack of dermis makes the wound heal with scarring and contraction . we can prepare a new kind of acellular dermal matrix ( adm ) by the method of naoh - maceration . first the acellular dermal matrix became vascularized within 3 weeks after implantation into full thickness skin defects in sd rats , then auto - split - thickness skin was overlaid on it . by animal experiments , we observed that the new kind of composite skin can reduce scarring and contraction of transplantation of razor - thin or split - thickness skin autograft 目前在臨床上治療大面積深度燒傷的方法是移植刃厚或斷層自體皮,但因缺乏足夠的真皮成分,常造成疤痕和攣縮,本實驗用naoh消蝕法研制出一種新的真皮基質( adm ) ,先將其移植于全厚皮膚缺損的大鼠背部創面,外覆蓋輻照豬皮保護3周,使其血管化,再在其上移植斷層自體皮,經動物實驗我們觀察到這種新型復合皮膚,可以減少單純移植刃厚或斷層自體皮造成疤痕和攣縮。

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 結果如下:皮下包埋卜周者,無細胞真皮基質漸與周圍組織粘附,顏色由蒼白轉紅;皮下包埋3周者,無細胞真皮基質與周圍組織緊密枯附,盾晰葉辯;術后卜周,包埋的基質面積變化較包埋前無統計學差異o川0引,術后4周包埋的無細胞真皮基質面積較包埋前縮小j刃刀5 ) 。光鏡下術后卜周,宿主的淋巳組織細胞、成纖維細胞浸入生長,釉附在膠原纖維上,少量血管內皮細胞浸入基質;術后34周,無細胞真皮基質內較多的血管形成,故可認為無細胞真皮基質免疫原性低,能誘導宿主的成纖維細胞、巨噬細胞浸入生長,為一種新型的真皮替代物。第四部分無細胞真皮基質與自體斷層皮片復合移棺的研究, sd大鼠10只,在其背部卜方造成全厚皮膚缺損的創面

An acellular dermal matrix was prepared from allogenic skin by removing epidermis with a hyperosmotic salt solution and cross - linking with glutaralaldehyde , then clear away acellular components in dermis with naoh - maceration . the light and sme observation of the acellular dermal matrix revealed that the epidermis and cellular component in dermis were eliminated 本研究共分四部分:第一部分無細胞真皮基質的制備用高滲鹽除去異體皮膚的表皮細胞,經戊二醛交聯后以低濃度naoh消蝕以除去真皮中的所有細胞成分,得到無細胞真皮基質。

We treat the porcine skin by 0 . 25 percent trypsin , 0 . 125 % trypsin , 2 . 5 u / ml dispase , hypertonic saline or hypertonic saline - trypsin / dispase . we find that after the skin has been incubated in 0 . 125 percent trypsin for 24h at 4 ? , the cells in the skin are all disintegrated . there are no significant differentiation between the acellular matrix treated by 0 . 125 , 0 . 25 perlent trypsin , 2 . 5 u / ml dispase and hypertonic saline - trypsin / dispase . but the cell ca n ' t be removed by using the hypertonic saline - sds 本研究通過對0 25胰酶不同脫細胞時間處理、不同濃度胰酶處理、 dispase脫細胞法、 im 、 zm高滲鹽水脫細胞法、高滲鹽水和胰酶或dispase混合脫細胞法的比較確認采用0 12盼胰酶, 4 , 244 。

One is the acellular lipid core of mature atherosclerotic plaques , but that doesn ' t really count , because macrophages are constantly arriving and eating bits of that core , and the only problem is that they can ' t then break it down after eating it , and eventually they die and become part of the problem 一是成熟的動脈粥樣硬化斑塊的非細胞脂質核,但是,這種脂質核并非真正脂質核心,因為巨噬細胞不斷來吃掉一點這種核心,唯一的問題是它們吃后不能消化,它們最終死亡并成為該問題的一部分。
