核仁形成體
英文
nucleolar organizer-
The ultrastructure of the merozoites of eimeria tenellawas observed and discribed. the pellicle consist of two layer membranes, the outer membrane was a continous covering enclosing the whole merozoites, while the inner pellicular complex is interrupted at the anterior and the micropore, and thicken to form the polar ring and micropore. there are 24 microtubules under the pellicle of the merozoite which originated from the polar ring, all of them are connected with the polar ring, and extend alongside the inner pellicular complex to the middle of the merozoite. the head of the merozoite consists of a conoid, an apical vesicule and polar ring. the conoid is a hollow truncated cone. the conoid and spical vesicule can stretch and contract. there are three or more rhoptry and a lot of micronemes. the nucleus has nucleolus. and two layer membranes
利用透射電鏡對柔嫩艾美耳球蟲裂殖子的超微結構進行了觀察描述.柔嫩艾美耳球蟲裂殖子的表膜由外膜和內膜復合體兩層組成，外膜連續，內膜復合體在頭部斷開形成極環，在其它部位斷開形成微孔；裂殖子的膜下微管24根，起始於極環，向後延伸至細胞核處；裂殖子的頭部由頂泡、錐體和極環組成，錐體和頂泡可以伸縮；柔嫩艾美耳球蟲裂殖子棒狀體3個以上，微線數量很多，二者都由電子緻密的結構組成；細胞核位於裂殖子的中後部，外被雙層膜，有電子緻密的核仁和染色質At low concentration of zn, the changes in ultrastructure were nuclei deformation, chloroplast swelling and disorder of thylakoid arrangement ; serious damages in ultrastructure caused by greater zn stress were indicated by scattered nucleoli, condensed chromatin, almost empty nuclei with nuclear membrane disrupted and nucleoplasm flowing into cytoplasm, swollen and partly dissolved cristae of mitochondria, disrupted and collapsed chloroplast envelopes, and some dissolved thylakoids that flew into cytoplasm
超微結構的變化也呈現加重趨勢，低濃度處理的變化為細胞核變形、葉綠體膨脹、類囊體排列紊亂；嚴重的超微結構的損傷是核仁散開、染色質凝集，細胞核幾乎成為空核和核膜破裂，核質散出；線粒體脊突膨脹和部分溶解；葉綠體膜斷裂、消失和部分類囊體溶解和散到細胞質中。Ebv gp350 and c3d bind selectively to the same site on the cr2, epitopes on scr - 1 and scr - 2 are necessary for the binding. as soon as c3d binds to scr - 1 and scr - 2, cr2 may cross - link - 8 - to memberane ig and form a " co - capping " structure, moreover, activate b lymphocyte through cd19, a component of cd19 / cd21 / cd81 / leul3 complex, signaling and / or nucleolin tyrosine phosphorylation independent on cd 19 signaling pathway
配體與scr l和scr 2結合后， crz與細胞膜免疫球蛋白（ inlg ）形成「共帽」 kofthofcccptor ）結構，並經過d19c 21兒81肚u13復合體中d19的信號轉導以及不依賴于cd途徑的核仁素（ nucleolin ）酪氨酸磷酸化激活b細胞。
