dermal tissue 中文意思是什麼
dermal tissue
解釋
皮部組織-
Our skin surface is " cuticular layer ", and cuticular lower part is " dermal layer " ; cuticular layer and true cortex are not completely close together " sticky " together, skin is in only certain zone by connective tissue closely " bind " go up in derma, certain place is done not have ; so, absorbed water when skin " swollen " when rising, " bind " the place that live is stayed by confine however and show cave shape ; look from the exterior, cutaneous surface just has sunken have dash forward, like furrow
我們的皮膚表面是一層表皮層，而表皮下方是真皮層；表皮層與真皮層並非完全緊密的黏在一起，表皮只在某些地帶由結締組織緊緊地綁在真皮上，某些地方則沒有；所以，當表皮吸了水腫起來時，綁住的地方卻被局限住而呈凹陷狀；從外觀看起來，皮膚的表面才有凹有突，像皺紋一樣。 -
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隻，在其背部卜方造成全厚皮膚缺損的創面 -
