Nucleolar associated chromatin
核仁相隨染色質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。Cells take diverse shapes. these are epithelial cords of block - like cells. as always, nucleoli and nuclear heterochromatin stain darkly with hematoxylin
不同形態的細胞。這些是立方細胞排列成的上皮索狀結構。總之,核仁與細胞核中的異染色質被蘇木精染成深色。The nuclei are monomorphic with inconspicuous nucleoli. the nuclear chromatin has somewhat granular appearance. mitotic actiity is not increased. ( same case as preious 2 illustrations )
瘤細胞核形態單一,核仁不明顯。核內染色質呈顆粒狀表現。有絲分裂活性未見增強。The meristematic nuclei in wheat nodule - like were very large and rounder, a nucleus generally possessed a nucleolus, some nucleoli had nucleolar vacuoles but only a nucleolus usually had a nucleolar vacuole
摘要在小麥類根瘤中,分生細胞核很大,而且較圓整,一般為一個核仁,有的核仁還有核仁泡,但通常一個核仁只有一個核仁泡,染色質較少,呈團塊狀分佈。The results of these early research work showed that rna polymerase iii transcription was localized in the nucleoplasm. however, with the development and the application of new technologies since 1990s, the controversy arose on the transcription sites of rna polymerase iii. in recent years, more and more scientists presumed that rna polymerase iii transcription might not occur in the nucleoplasm but in the nucleoli
自上個世紀八十年代初期,人們相繼運用細胞化學染色、電鏡放射自顯影等進行研究的結果表明: rna聚合酶的轉錄發生在核質中,但隨著新的研究技術的發展和應用,人們卻發現rna聚合酶的轉錄可能發生在核仁中,從而對早期的研究結果提出了質疑。The nuclei are ooid or round with finely reticular chromatin and rare punctate nucleoli. the cytoplasm is pale eosinophilic or clear
細胞核呈圓形或卵圓形,染色質為精細的網路狀,稀疏的斑點狀核仁。胞漿蒼白色或透明,嗜酸性染色。During the stages of primary and secondary spermatogonium, components of the nucleolus, called chromatoid bodies ( cb ), are excluded from the nucleus
精原細胞階段,部分核仁物質外排,成為擬染色質小體,其上聚集一群線粒體,構成「線粒體區」 。Mitochondria and ribosomes are hard to see, and the ribosome are found to adhere on the surface of endoplasmic reticulum ; golgi body and lysosome do not exist, membranous ring emerges at the secondary spermatocyte stage. the organelles change into pre - acrosome vesicles at middle spermatid stage, and finally pre - acrosome forms acrosome. 2

在生精細胞階段核內染色質有不同程度的凝集,在成熟精子中核質分化成泡狀核和絲狀核,整個精子發生過程無核仁發現。Cultured epithelial cell undergoing division. this cell is in prophase of mitosis. microtubules are shown in green, actin is in red and mitotic chromosomes are colored blue
以上兩圖為正處于有絲分裂前期的動物上皮細胞。綠色的是微絲,紅色為肌動蛋白,染色質高度螺旋成為粗短的染色體(藍色) ,核膜核仁逐漸解體,染色體不規則地分佈於細胞內。分享友人
