His found that a large number of crystal cell is one of the typical salt - resistant characteristics in high - saltnity halophytes , and the distribution of salt hydronium inside plants appears obvious regional characteristic of many arrangements : salt - hydronium - - vacuole - - despersed singal crystal cell or vacuole bags which contain salts - - vacuole bags or crystal cell in groups or distributed as groups - - little consecutive crystal cell ring of organ periphery - - consecutive crystal cell ring of organ periphery 發現大量的含晶細胞是高鹽度鹽生植物的一種代表性的抗鹽結構特征,并且鹽離子在植物體內的分布呈現出明顯的多層次性的區域化特征:鹽離子液泡分散的單個含晶細胞或含鹽液泡包成群或成堆分布的含鹽液泡包或含晶細胞器官外周不太連續的含晶細胞環器官外周連續的含晶細胞環。

The results showed that , at 12 48 hrs post infection , the bursal epithelial cells bore swollen and necrotic shape . the lymphoid cells in the medulla and cortex of lymphoid follicles had various degrees of degeneration and necrosis . the lymphoid follicles showed glandular structures or cystic vacuoles owing to the prolifetation of bursal epithelium and lymphocyte depletion . lymphoid follicles from bursa at 72 144 hrs post inoculation became atropy . marked proliferation of interfollicular and interstitial connective tissue was present 結果表明,病毒感染后12 48小時,雛雞法氏囊粘膜上皮細胞腫脹、壞死脫落,淋巴濾泡髓質部及皮質部淋巴細胞不同程度變性、壞死、排空,形成腺管樣結構或囊狀空泡,接毒后72 144小時,法氏囊淋巴濾泡淋巴細胞壞死排空,淋巴濾泡萎縮,網狀結締組織大量增生,而胚胎發育時期,法氏囊粘膜上皮腫脹變性,法氏囊淋巴濾泡形成延遲或不完整,淋巴濾泡內淋巴細胞缺乏或空虛。

The steady dead generation and time that was caused by the isolated virus was certain by chicken embryo which was inoculated on seven or nine days . the histopathological changs of the infectious stunting syndrom were studied by the way of ordinary paraffin section and he dying . the experimental result were as follows : the test proved that the changes of the chicken embryo were different in different stage . the chicken embryo dead in a week after it inoculated . the body was dropsy and hemorrhage . dead before it hatched out , the embyo body were dropsy , pale and slime . the liver was yellow and swolled , gallbladder ( vesica fellea ) was filled with bile . bursa and glandula thymus analosis . the kindey dropsy . bowel lamina were humble , dilatation . gas and yellow foam were filled the bowel . histopathological changes were that , in early stage , obvious changes of liver and kindey were dropsy , hemorrhage and necrosis . two types eosinophilic intranuclear inclusion bodies including large round and little granular were present in cells of the above organs . the obvious changes of bursa were dropsy , adverse folliiculated growth and little lymphocytes proliferating , 19 - 21 days chicken embryo , one or two big empty vacuoles were prensent in cells of liver and kindey . the number of the folliculi was growing , the vacuoles between cells were larger 膽囊充盈、其內充滿稀薄的膽汁;法氏囊、胸腺萎縮,腸道擴張、腸壁菲薄、內充滿氣體及黃色泡沫狀物;腎臟腫大。病理組織學變化方面,早期肝臟、腎臟、腸主要以出血、水腫和壞死為主,且肝細胞核及腎小管的上皮細胞核內均發現有核內包涵體,包涵體呈嗜酸性,為大型圓形包涵體或不規則的顆粒狀;法氏囊則以水腫、濾泡發育不良、小型淋巴細胞數量增多為主。 19 21日齡雞胚肝細胞、腎小管上皮細胞的胞漿內出現1 2各大的空泡,法氏囊濾泡數目增多細胞間有較大空隙。

Whereas pigments are able to alter a petal ' s colour even when they are inside a vacuole , because the cell contents surrounding the vacuole are transparent , smelly molecules must find a route to the sniffer ' s nose by getting out of the cell and evaporating 色素即便是位于液泡中,它也能改變花瓣的顏色,這是因為液泡外包繞的細胞內容物是透明的,而氣味分子必須穿過細胞并揮發才能為聞者所聞。

Na + / h + antiporter is one sort of protein which on the membrane or vacuole membrane , they can transport na + retrorsely out of the cell or into the vacuole . most of the algaes and the salt plants have this kind of protein Na ~ + h ~ +運輸蛋白是位于質膜和液泡上的一類運輸蛋白,它可以逆電化學梯度將na ~ +排出細胞外或區隔化于液泡中,普遍存在于藻類與鹽生植物中。

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,呈團塊狀分布。

Like certain other bacterial pathogens , chlamydiae induce epithelial cells ? in this case , those lining genital tracts , eyelids or lungs ? to absorb them within a membrane - bound sac , or vacuole 一如某些病原菌,披衣菌會誘使上皮細胞利用由細胞膜包圍而成的囊泡,將自己納入細胞內;對披衣菌而言,主要的感染對象是生殖道、眼瞼或肺臟的表皮細胞。

Aleurone grain ( aleurone body ) a modified vacuole found in the embryo and endosperm of seeds and containing mostly reserve proteins , but also phytic acid and various enzymes associated with mobilization ( digestion ) of these reserves 糊粉粒(糊粉體) :在種子胚或胚乳中發現的經過修飾的液泡,里面包含許多儲藏蛋白,植酸和各種各樣的酶。

One potential drug could interfere with the proteins ' activity in a way that would force the entry vacuole to fuse with lysosomes , triggering an immune attack right after the chlamydiae invade the cell 其中一種的可能作用,在于干擾這些蛋白質的活性,迫使入侵囊泡與溶小體融合,而在披衣菌侵入細胞后,即迅速引發免疫攻擊。

This new method is basically different from the traditional way for gcv sap , which begins from the isolation of the protoplast of guard cells , and then vacuoles are isolated from protoplasts 用玻璃毛細管從液泡取樣的方法,克服了傳統方法從分離保衛細胞原生質體入手,再分離液泡的復雜、污染機會多、工作量極大等缺點。

Healthy cells typically attempt to kill internalized pathogens by having the entry vacuoles fuse with lysosomes , cellular structures containing enzymes that chop up proteins , lipids and dna 一般來說,健康的細胞會以溶小體與囊泡融合,將進入細胞的病原菌殺死;因為溶小體當中帶有分解蛋白質、脂質及dna的酵素。

Note the clear vacuoles in the colloid next to the epithelium where the increased activity of the epithelium to produce increased thyroid hormone has led to scalloping out of the colloid 臨近上皮細胞的膠質內可見清晰空泡,此處上皮組織細胞活躍,甲狀腺激素分泌增多,形成扇形的膠質邊緣。

Another drug might incapacitate the mechanisms the bacteria use to divert lipids from the host cell to the chlamydial vacuole , halting the trespassers ' ability to hide 另一種藥物,則是造成披衣菌挪用宿主細胞脂質的機制失效,使得這些非法入侵者無法藏匿。

However , it is hard to find out direct evidences for the accumulation of foreign k + in guard cell vacuoles for stomatal opening to satisfy the chemiosmotic hypothesis 然而該假說缺乏k ~ +等物質在滲透調節的關鍵部位? ?保衛細胞液泡中積累或耗散的直接證據。

The protein inclusions in a granular appearance accumulated in the central vacuole and starch grains generally in the cytoplasm of ordinary parenchyma cells 免疫熒光和電鏡免疫細胞化學定位證明,它們是貯藏蛋白質細胞的液泡蛋白質內含物的主要成分。

Nitrate may be converted to ammoium in the roots , or is carried to shoots and leaves and either stored in the vacuole or converted to ammonium 硝酸鹽可能在植物根部被轉化為銨,或被運送到植物嫩芽和葉片組織中,或存儲于液泡中或被轉化為銨。

This is a signet ring cell pattern of adenocarcinoma in which the cells are filled with mucin vacuoles that push the nucleus to one side , as shown at the arrow 如圖腺癌表現為印戒細胞癌,細胞里充滿黏液空泡把核擠向一邊,如箭頭所示。
