Thus , it will help elucidate the development , self tolerance of self autoreactive b lymphocyte repetoire to investigate the generation of naa . researches on the function of naa will help clarify the significance of naa ' s existence . the exploration of biological nature , encoded gene and the difference or relation between naa and pathological autoantibody will shed much light on the pathological mechanism and treament of autoimmune disease 因此,對naa產生機理的揭示將有助于回答免疫學b細胞產生、發育以及自身耐受的問題;對naa功能的研究有助于進一步明確naa對機體的意義;對naa的特性、編碼基因、與病理性自身抗體界限和關系的研究可能對自身第四軍醫大學碩士學位論文免疫疾病的發病機制和治療提供有益的線索。
It has been demonstrated directly or indirectly - 7 - that ak auto ab is an important element in the immune network and plays a important role in maintaining physiological functions , clearing aged cells and metabolic products , regulating immune responses and protecting against infection . in some pathological states such as psoriasis and contact dermatitis , a certain serum level of the antibody could inhibit the progression of the diseases , and is beneficial to the recovery from the diseases . after a long time studies on the production and regulation mechanism of physiological and pathological auto antibodies , meanwhile , experiencing an intensive academic debating on whether naas a " horror autotoxicus " or a " gnothi seaution ( know yourself ) " , a common viewpoint has been achieved that naa is of clinical significance in the treatment of immunity diseases for it ' s function in the immune system stability , immunoglobulin y and polyclonal ak auto abs have been used in treating inflammatory dermatitis , and recombinant antibody is under investigating 抗角蛋白自身抗體( akautoab )是naa的重要組成部分,以往實驗通過雜交瘤技術、免疫親和層析技術和噬菌體抗體庫技術分別獲得單克隆akautoab 、健康人血清多克隆akautoab和基因工程人akautoab ,并對akautoab免疫學特性及在體生理和病理意義進行了廣泛的研究,直接或間接地發現akautoab是機體正常免疫調節網絡的組成部分,在維護某些生理狀態的穩定、清理衰老細胞及代謝產物、調節免疫和抗感染等方面起到重要作用;在某些病理情況下(如銀屑病、接觸性皮炎等) ,體內akautoab的組分和滴度會發生變化,而正常水平的akautoab則有利于限制病情的發展,促進損傷的修復。
No callus occurred from hairy roots on medium lacking 2 , 4 - d . high concentration ( l . 0mg / 1 ) of 2 , 4 - d could induce much more calli , but it obstructed the growth of calli and followed buds differentiation . the result of callus induction showed that the optimum medium for callus induction was ms + 0 . 5mg / l 2 , 4 - d + 0 . 5mg / l 6 - ba and ms + 0 愈傷組織誘導最佳培養基為: ms 05mg l個d 05mg l ba ,愈傷組織生長的最佳培養基為ms 0ling 12 , 4 d cling 16ea ;愈傷組織能在不含激素的培養基上自發地分化出不定芽,但分化頻率較低,而6ea對不定芽的分化作用較明顯,配合使用6習a和naa對芽的誘導及得芽率較好,不定芽誘導的最佳培養基為ms 10mgilnaa 05mg lia培養基。
The regeneration system of tobacco was established . the adventitious shoots were induced from leaf explants of tobacco based on ms basal medium supple - - mented with 2 . 0mg / l 6 - ba and 0 . 3mg / l naa . then the regenerated plants were rooted on ms medium containing 0 . 3mg / l naa 植株再生體系的建立采用無菌苗煙草葉片為外植體,以ms為基本培養基,篩選出ms + 6 - ba2 . 0mg l + naa0 . 3mg l以誘導不定芽的分化,并于ms + naa0 . 3mg l的pa碩士學位論文v沉了砂“工隊nk ”主根培養基上生根,獲得完整再生植株。
