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，它也能改变花瓣的颜色，这是因为液泡外包绕的细胞内容物是透明的，而气味分子必须穿过细胞并挥发才能为闻者所闻。
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 胆囊充盈、其内充满稀薄的胆汁；法氏囊、胸腺萎缩，肠道扩张、肠壁菲薄、内充满气体及黄色泡沫状物；肾脏肿大。病理组织学变化方面，早期肝脏、肾脏、肠主要以出血、水肿和坏死为主，且肝细胞核及肾小管的上皮细胞核内均发现有核内包涵体，包涵体呈嗜酸性，为大型圆形包涵体或不规则的颗粒状；法氏囊则以水肿、滤泡发育不良、小型淋巴细胞数量增多为主。 19 21日龄鸡胚肝细胞、肾小管上皮细胞的胞浆内出现1 2各大的空泡，法氏囊滤泡数目增多细胞间有较大空隙。
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 结果表明，病毒感染后12 48小时，雏鸡法氏囊粘膜上皮细胞肿胀、坏死脱落，淋巴滤泡髓质部及皮质部淋巴细胞不同程度变性、坏死、排空，形成腺管样结构或囊状空泡，接毒后72 144小时，法氏囊淋巴滤泡淋巴细胞坏死排空，淋巴滤泡萎缩，网状结缔组织大量增生，而胚胎发育时期，法氏囊粘膜上皮肿胀变性，法氏囊淋巴滤泡形成延迟或不完整，淋巴滤泡内淋巴细胞缺乏或空虚。
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 发现大量的含晶细胞是高盐度盐生植物的一种代表性的抗盐结构特征，并且盐离子在植物体内的分布呈现出明显的多层次性的区域化特征：盐离子液泡分散的单个含晶细胞或含盐液泡包成群或成堆分布的含盐液泡包或含晶细胞器官外周不太连续的含晶细胞环器官外周连续的含晶细胞环。
