血管周圍細胞的營養不足,引起外膜的變性。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We also investigated the pathological changes of mouse liver, thymus and cerebrum cortex challenged by so2 inhalation by in vivo tests. we studied the apoptotic induction on mouse spleen cells and cytotoxicity of human embryo lung fibroblasts of so2 derivatives by in vitro tests. in vivo tests of sulfur dioxide inhalation showed : ( 1 ) effects on mouse lung of so2 challenge : we found no significant apoptotic changes induced by so2 inhalation but obvious pathological changes of lung with vacuolating of osmiophilic multilamellar bodies which maybe related with the decrease of surfacant and decrease of microvillus of type ii alveolar cells ; we also found thickening of part of basement lamina between type i alveolar cells and capillary endothelium cells which may inhibit the dispersion of oxygen and contribute to lung dysfunction
二氧化硫熏氣染毒的體內實驗結果表明,在本次實驗的濃度范圍內( 56mg m ~ 3 、 112mg m ~ 3 、 168mg m ~ 3低、中、高三個濃度) : ( 1 )通過透射電鏡、 dna凝膠電泳分析和流式細胞分析發現二氧化硫吸入染毒一周對小鼠肺臟沒有明顯的凋亡誘導作用,但通過透射電鏡觀察發現二氧化硫可引起肺臟明顯的超微結構改變,引起型肺泡上皮細胞板層體空泡化,微絨毛減少,線粒體緻密化或腫脹變性;肺泡血管內皮細胞和型肺泡上皮細胞之間基膜增厚,使氧氣彌散功能出現障礙,從而降低肺功能。This is a renal biopsy in which there is a focal lesion centered around a blood vessel
