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Dendritic cells ( dc ) is the most powerful apc, which can markedly increase the antigen - presentation capacity by maximizing the pepitide - mhc complexes on the cell surface and upregulating the co - stimulatory ligands b7 - 1 and b7 - 2, adhesion moleculees such as il - 12 that promote full activation of lymphocytes. full activation of antigen - specific t cells requires two signals - one signal coming via the tcr and the other signal through engagment of co - stimulatary molecules. t cells receiving one signal via their tcr are turned off by mhc ( major histocompatibility complex ), via t cell cd28 binding to b7 on the dc induce tlymphokine and t cell proliferatiion
T細胞介導的細胞免疫在控制腫瘤生長方面發揮著重要作用, t細胞在發揮抗瘤效應(分泌細胞因子和直接殺傷)之前必須先經過活化,體內專職抗原提呈細胞( apc )細胞並使其活化,樹突狀細胞( dendriticcell , dc )為t細胞的激活提供雙重信號, t細胞藉助tcr識別由dcmhc分子遞交的抗原肽后,通過tcr - cd3復合體傳遞抗原特異性識別信號(第一信號) ,以cd28為主的t細胞表面輔佐分子識別dc表面b7分子,傳遞非特異性協同刺激信號(第二信號) ,在機體抗腫瘤免疫應答中處于核心地位。The results obtained in our laboratory in the past decade years showed, apoplast calmodulin in plant kingdom may regulate a lot of growth and development process of plant, such as accelerating the proliferation of angelica dahurica suspension cells and the proplast cell regeneration, startup the pollen germination of many plants " pollen and accelerating the elongation of the pollen tube, stimulating the redox of corn root " s cell, inducing the expression of light independent rbss gene, and participating in the regulation of the restraining function of al ~ ( 3 + ) to pollen tube germination
我室多年的研究結果表明,植物質外體cam可能做為多肽第一信使調節著植物體諸多的生長發育過程:如促進白芷懸浮細胞的細胞增殖和原生質體壁再生,啟動並促進多種花粉的萌發和花粉管的伸長,刺激玉米根細胞的氧化還原反應,誘導rbcs基因光不依賴的表達,以及參與調節胞外al ~ ( 3 + )對花粉萌發的抑制效應等。Effective activation of antigen - specific t cells not only requires the first signal transduction through t - cell receptor ( tcr ) binding with peptide - mhc complex on the antigen presenting cell ( apc ), but also needs the second signal, termed costimulation. costimulation critical to the degree and consequence of t cell activation is provided by interaction between soluble factors or cell - surface molecules on the t cell and on the apc
而t細胞的活化除需要t細胞受體( tcr )與抗原呈遞細胞( antigenpresentingcell , apc )表面的抗原肽- mhc復合物結合所形成的第一信號外,還需要t細胞和apc表面的其它膜分子結合所提供的共刺激信號(亦稱第二信號或輔助刺激信號, costimulatorysignal )的參與。In the first part, we observed the changes of expressions of type i receptor of il - 1 in the rat and mouse brain after intraperitoneally administration of different kinds and doses antigens respectively. in the second part including two experiments we cloned rat il - 6r ' s genes by pcr, expressed them in e. coli dh5 a and cos - 7 cell, and produced il - 6r ' s polyclonal antibody which is proved having more high liter, affinity and specificity 1
第一部分採用不同種類和劑量的抗原刺激,分兩個實驗,觀察了大、小鼠腦內il - 1的i型受體表達的變化,探討了腦內參與免疫調控的核團和細胞類型;第二部分分兩個實驗,運用pcr技術克隆了大鼠il - 6r的基因並進行了原核和真核表達,制備了特異性高、親和力強和較高效價的抗il - 6r多克隆抗體,為進一步進行il - 6r的研究奠定了基礎。Seen in this way, a group of white blood cells called t cells are the frontline soldiers of immune defense, engaging inading pathogens head on
從這點看,一組稱為t細胞的血細胞處在免疫防線的第一線,防止病原體入侵。Seen in this way, a group of white blood cells called t cells are the frontline soldiers of immune defense, engaging invading pathogens head on
