中子增殖因數
英文
neutron multiplication factor-
By the compounds of submandibular gland cells and collagen sponges. we investigate the optimal cell denisity of tissue engineered compound of submandibular gland cells and collagen sponges, the cellular compatibility of tissue engineered compound of submandibular gland cells on the collagen sponges with different porosity and the influence of epidermal growth factor on the adherence of submandibular gland cell to collagen sponge. our studies can primary provide theoretical ground work to form the model in vitro of tissue engineering smg
在本研究中，以初步探討體外頜下腺細胞與膠原海綿支架相互作用為目的，採用體外分離培養sd大鼠頜下腺細胞，然後接種于膠原海綿支架上體外復合培養的方法；從不同接種細胞濃度對細胞一支架復合物影響，同一接種細胞濃度在不同孔隙率的支架上黏附、增殖的情況及表皮生長因子（ egf ）對頜下腺細胞的促增殖作用，促細胞在支架上黏附等三方面入手，初步研究了頜下腺細胞與膠原海綿相互作用的影響因素，為進一步在體外及體內構建較為理想的組織工程化頜下腺提供理論參數和實驗依據。The maximum heating rate of absorber is o. skw. ? h / ? inside experiment fuel rod is much lower than that outside experiment device. influence of absorber movement on thermal neutron flux decreases, as radial distance between absorber and measuring point increases
給出了硼不銹鋼和銀分別做為吸收體的兩種方案的計算結果，即有效增殖因子keff 、中子通量密度分佈、燃料棒功率、吸收體組分及其發熱，並進行了分析、比較，為瞬態試驗裝置的設計提供了參數。Methods : the effects of different neurotrophic factors on the growth and differentiation of neural stem cells were observed by cells counting and immunofluorescence staining. the levels of rara mrna and rxra mrna in differentiated neural stem cells were assayed by rt - pcr. agarose gel electrophoresis and image analysis
方法應用細胞計數和免疫熒光細胞化學法，研究不同神經營養因子對神經幹細胞增殖及分化的影響；應用rt - pcr 、瓊脂糖凝膠電泳和紫外分光圖象分析法檢測神經幹細胞分化過程中rar和rxr mrna表達量的改變。結果1
