盾形葉 的英文怎麼說

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

In this study, systems of rapid propagation of the cultivars such as d. zingiberensis, d. panthaica and d. composite were setup to find the best way to meet the need of producing, and to establish the base of introduction, breeding and cultivar improvement of foreign dioscorea with high diosgenin ; in addition, there are two strategies to obtain polyploids combining with chromosome engineering : screeding natural mutations and mutation breeding were carred out on d. zmgiberensis. exploratively studies were done on rapid propagation of the three dioscorea plants. the result showed : explants of d. pathaica obtained the appreciate propagation efficency on ms + ba1. 0mg / l + naa0. 1mg / l, ms basic medium containing 6. 0mg - 1 ba, l. 0mg - 1 kt and sucrose at 30gl - 1 or 60g1 - 1 was the appreciate medium for microtuberization

三種薯蕷屬植物離體再生體系培養條件的探索試驗結果表明：黃山藥外植體適宜的增殖培養基為ms + ba1 . 0mg / l + naa0 . 1mg / l ，微型塊莖誘導為ms + ba6 . 0mg / l + kt1 . 0mg / l + 3蔗糖，高濃度的蔗糖含量（ 6 ）能提高微型薯蕷的誘導率，但對其誘導起關鍵作用的還是ba的濃度；菊葉薯蕷增殖效果較好的培養基為ms + ba1 . 0mg / l ，以ms培養基為誘導微型薯蕷的最佳選擇，誘導率可達50 ；盾葉薯蕷最適宜的增殖培養基為ms + ba2 . 0mg / l ，在誘導微型薯蕷的實驗中發現，當ba濃度為6 . 0mg / l和8 . 0mg / l時， 15d左右節間處膨大形成綠色圓球狀小塊，但繼續培養其上則開始分化芽。

The diversities, of which 15 dioscorea zingiberensis local populations in characteristics of morphology, climate and physiology, showed the significant inner genetic diversities of the species of dioscorea zingiberensis. 2

本實驗所選的15個地方居群在形態性狀、生理性狀和物候期等的多樣性表現，說明了盾葉薯蕷存在著豐富的遺傳性狀的多樣性。

By means of polyaerylamide gel electrophoresis, peroxidase isozyme, esterase isozyme and a - amylase isozyme of dioscorea zingiberensis, which were gathered from different growing environment conditions, were analyzed. with the results of 3 kinds of isozyme analysis and the analysis of 15 populations morphology and climate, dioscorea zingiberensis were divided into 5 ecotypes. the main results were shown as follows : 1

本研究以來自我國秦嶺山脈以南的甘肅、陜西、湖北、湖南、四川及雲南各省的盾葉薯蕷為試驗材料，通過對盾葉薯蕷的pox 、 est和a - amy3種酶的同工酶進行聚丙烯酰胺凝膠電泳分析，結合其形態性狀和物候期等生物學特徵，進行生態型的劃分，所得結論如下： 1

Through the clustering analysis with the data of isozyme analysis, morphology analysis and climate analysis, 15 local populations were divided into 5 ecotypes. ecotype i included shanxi - fengxian, shanxi - shiquan, hubei - yunxi, hubei - wudang, hubei - yichang, hunan - anhua, hunan - shimen. gansu - liangdang population was belong to ecotype ii

由於存在環境異質性，使得盾葉薯蕷各居群在長期的生態適應過程中，發生了生理以及形態等生物學特性的變異，這些變異有的是暫時性的，有的則在遺傳上被固定下來。
