autograft n.【醫學】自體移植。

autograph

The bone - patellar tendon - bone autograft is an optimal source of graft material because of its initial strength , tendon bone interface , microstructure , and associated bone blocks that allow bone to bone healing and rigid fixation . therefore the patellar ligament has been considered the ideal graft material for reconstruction of the anterior cruciate ligament 其中由于髕腱的強度足夠大,而且它與acl有相似的解剖學表現,血運特征和組織結構, bpb ( bone - pateller - bone )又提供了骨與骨的連接方式,這種方式明顯優于其它組織。

However , in spite of the persistence of skeletal muscle along the graft , regenerated nerve fibers showed a good morphological pattern of regeneration , providing further evidence that the muscle - vein - combined grafting technique represents an effective surgical alternative to the classical fresh nerve autograft for the repair of peripheral nerve defects 雖然移植后骨骼肌纖維持續存在,但是,神經纖維卻顯示了較好的再生形態學模式,這進一步證實:骨骼肌-血管結合的移植物技術能夠有效修復周圍神經的缺損,可用來替代經典的新鮮自體神經移植,應用前景看好。

Result the fresh and freeze - stored fascial chondrocytes were superior to free grafts of chondrocytes in potentiality of formation of new cartilaginous tissue , structure and metabolism of newly formed tissue . relatively good results were also obtained similarly by using fresh autografts of periosteum and cartilage 結果新鮮和凍存的筋膜軟骨細胞移植在結構、形成新的軟骨組織能力、代謝活性方面均優于游離軟骨細胞移植;新鮮的自體骨膜和軟骨移植同樣可獲得較好的結果。

Despite publications on nerve conduits as an alternative for peripheral nerve repair , autologous nerve grafting is still the standard care for treatment of a nerve gap in the clinical situation ; however , the use of the skeletal muscle tissue technique can be added to the surgeon ' s arsenal of peripheral nerve repair tools , especially for bridging short nerve defects or when traditional nerve autografts cannot be employed 雖然目前有許多應用神經導管修復周圍神經的報道,但是,自體神經移植物仍舊是臨床治療神經缺損的金標準;盡管如此,骨骼肌組織的應用也是外科醫師在修復周圍神經缺損時的備選方法,尤其是當神經缺損長度較短或用傳統的自體移植物修復有困難的時候。

In control group , simple split - thickness skin autografts were transplanted on the rat ' s full thicknss defect wounds of dorsolumbar . 2 weeks , 3 weeks , and 4 weeks after transplantation ordinary observation and histological observation were employed . in comparison with the control group , the composite transplantation skin had no remarkable contraction and have a fine exterior 術后2周、 3周、 4周職材作大體形態學觀察,組織學檢查,結果發現與對照組相比,復合移植區痰痕增生較輕,斷層自體皮與無細胞真皮基質復合移植后外觀優于單純斷層自體皮移植。

This study evaluated the biomechanical properties of the femur - acl - tibia complex following acl reconstruction with the medial one - third pt autograft . experiment investigation random contrast balance , forty - two new zealand white rabbits was divided into three groups . bpb autograft contains blood vessels group ( i ) , bpb autograft which have no blood vessels group ( ii ) , blank contrl group ( illgroup ) . thirty - six new zealand white rabbits underwent acl reconstrution using a medial one - third pt autograft 實驗研究在隨機、對照、均衡的原則下進行,將42只新西蘭成年大白兔隨機分為帶血管蒂的bpb移植物組(組) 、不帶血管蒂的bpb移植物組(組)和空白對照組(組) ,分別予相應處理造模,然后在術后8周、 12周、 16周取股骨? ? acl ( bpb移植物) ?脛骨標本進行生物力學測試。

Autografts , allografts and artificial bone substitutes are general methods in reparation of bone defect . but all of these methods have there inherent problems and limitations . autografts are limited by the lack of adequate supply and donor site morbidity 目前臨床常用修復骨缺損的方法有自體骨移植、異體骨移植、基質材料替代,其中自體骨移植的骨來源有限,異體骨移植和基質材料替代缺乏種子細胞支持。

Among the different materials that have been used so far in alternative to traditional fresh nerve autografts , fresh muscle - vein combined conduits ( made by a vein segment filled with fresh skeletal muscle ) proved to be particularly effective 在已經投入應用的諸多新鮮自體神經移植物的替代物中,新鮮的骨骼肌-血管結合導管(由新鮮骨骼肌填充于血管片段中制成)經驗證是一種修復效果特別好的材料。

In clinic , the autograft bone - patellar tendon - bone is little used because of the donor - site complications , but the other two grafts are used more as they have less trauma and enough knee stability without donor - site complication 因受供端并發癥的影響,自體骨髕腱骨的應用已呈減少趨勢,而后兩者因不存在供端并發癥,創傷更小,也足以恢復膝關節的穩定性,應用呈增多趨勢。

6 ( 5 ) cf , a kind of phloem transport tracer , was used to test the functioning of the wound phloem across the graft union . 6 ( 5 ) cf was introduced from the leaves of the scion into autograft of c24 inflorescence stem 8 days after grafting 將6 ( 5 ) cf引入到接穗的葉片中,熒光顯微鏡觀察結果表明: c24擬南芥花序軸自體嫁接后8d ,在砧木的韌皮部中中可檢測到6 ( 5 ) cf的存在。

Intra - articular reconstruction is the most frequently used and effectual method . biologic tissues , whether autografts or allografts , or artificial tissues , are the most frequently used anterior cruciate ligament substitute 而關節內重建無疑是最常用而有效的方法,關節內重建選擇的移植物有自體組織、界體組織以及人工組織。

In autograft of arabidopsis thaliana ( columbia24 ecotype ) grafted in the position of hypocotyls , wound xylem and sieve elements were differentiated in the tissues both of scion and stock 4 days after grafting C24擬南芥下胚軸自體嫁接后4d ,在接穗和砧木中就已有管狀分子和篩分子的分化。

In autograft from inflorescence stems callus tissue was found 4 days after grafting . no xylem and sieve elements were differentiated in both scion and stock in this period C24擬南芥花序軸自體嫁接后4d ,嫁接面處愈傷組織開始形成,嫁接體雙方還沒有分化出管狀分子和篩分子。

Tissue - engineered skin substitutes provided a feasibility to overcome the shortage of skin autograft by culturing keratinocytes and dermal fibroblasts in vitro 體外成功的培養人表皮細胞和成纖維細胞為組織工程皮膚克服皮膚自體移植物的不足提供了可行性。

Using semithin sections techniques the histological development of the autograft arabidopsis thaliana ( columbia24 ecotype ) were examined 采用半薄切片技術,對c24擬南芥自體嫁接組合嫁接體的發育過程進行了組織學觀察。

Autograft bone - patellar tendon - bone , hamstring tendon , allograft bone - patellar tendon - bone are selected commonly by arthroscopy doctors 自體骨髕腱骨, ?繩肌腱,異體骨髕腱骨是關節鏡醫生最常選用的三種移植物。
