| 2. | Result : the histological structure of anencephalus differentiates primitively and grows very slowly
结果：无脑儿食管的组织学结构较正常胎儿分化较低，发育迟缓。 |
| 3. | Purpose : to study the anatomical and histological structure of colon of congenital malformation fetus , to discuss the relationships between several malformations and the development of colon
摘要目的：研究先天性畸形胎儿结肠的解剖及组织学结构，探讨几种畸形与结肠发育之间的关系。 |
| 4. | Method : use morphological method to dissect and observe the colon of congenital malformation fetus , make - up the paraffin sections and observe the histological structures under the light - microscope
方法：应用形态学方法，对先天性畸形胎儿结肠进行解剖、观察，并制成组织切片，在光学显微镜下观察其组织学结构。 |
| 5. | The structure of oviduct : 1 . anatomy and histological structure . a pair of oviducts originates from the anterolateral part of the ovary , and ends at the female genital pores lying in the basipodite of the sixth thorax appendage
、输卵管结构主要发现如下： 1 、解剖及组织学结构日本沼虾输卵管一对，发自卵巢两侧，终止于第3步足基节上。 |
| 6. | 9 . the gonad development of g . przewalskii can be divided into 6 stages . the development of oocytes from phase 3 to phase 4 was synchronous , the histological structure of the ovary and testis came back to stage ii after reproduction
青海湖裸鲤的性腺发育可分为6期，卵母细胞从第3时相发育到第4时相基本同步，产后卵巢和精巢的组织学结构回复到期。 |
| 7. | We found nuclear deformation lymphocytes with increased heterochromatin and impaired thymus epithelium cells with increased lysosomes and deformation of mitochondrias . ( 4 ) effects on mouse liver of so2 challenge : so2 can cause significant liver injury . he staining showed several kinds of necrosis of liver including spot necrosis , focal necrosis and submassive necrosis infiltrated with lymphocytes , monocytes , few neutrophils and eosinophils ; tem observation showed fatty degeneration with dispersion of fatty droplets and dilation of rough endoplasmic reticulums , acid degeneration with significant hyperplasia of mitochondrias , necrosis of hepatocytes with karyorrhexis and other organelles losing their normal structure
( 4 )二氧化硫染毒对小鼠肝脏的组织学结构有明显影响，可引起肝脏点状坏死、灶状坏死甚至片状坏死，伴随不同程度的炎性细胞浸润；透射电镜观察发现二氧化硫可引起肝细胞脂肪变性、嗜酸性颗粒变和坏死，脂肪变肝细胞中可见大小不等的脂滴存在，嗜酸性颗粒变肝细胞中可见线粒体明显增生，坏死肝细胞可见细胞核结构破坏，细胞器减少，细胞膜不完整。 |
| 8. | Result : in three categories and ten examples of congenital malformation fetus , the morphological and histological structures of colon in syndactyly and sxtrodactyly fetus have no obvious abnormity ; the colon ' s structure shows abnormity in omphalo - thoracopagus twins ; the colon ' s structure was insufficient development in anencephaly fetus
结果：三类10例先天性畸形胎儿中，并缺指畸形胎儿结肠的形态学及组织学结构无明显异常；胸腹联体胎儿结肠结构异常；无脑儿结肠组织结构发育不全。 |
| 9. | These suggested that so2 may affect body immunity to a certain degree . ( 3 ) effects on mouse thymus of so2 challenge : he staining showed no obvious structure changes of thymus in all treatment groups compaired with the control group ; the ultrastructure of thymus can be seen injured in so2 treated groups from tem observation
( 3 )二氧化硫染毒对小鼠胸腺组织学结构影响较小：用透射电镜观察发现胸腺组织中有部分淋巴细胞变形且异染色质增多，胸腺上皮细胞中可见次级溶酶体增多，线粒体变形，这说明二氧化硫可能对中枢免疫器官也有一定的不良影响。 |
