| 1. | Between the secretory cell and the basal cell the cell wall exists the similar structure of casparian strip through which much plasmodesma goes 头细胞和基细胞相邻的细胞壁上有类似凯丝带增厚的细胞壁,壁间有较粗的胞间连丝通过。 |
| 2. | On the under epidermis and petiole epidermis of sophora flavescens ait . is founded salt gland which has a secretory cell and a basal cell for the first time 首次在苦参叶的下表皮及叶柄的表皮上发现了盐腺。该盐腺由一个头细胞和一个基细胞构成。 |
| 3. | Special subepidermal cells were found to exist beneath the epidermises of h . cordata stems and leaves and secretory cells were found to exist in the cortex and pith of the stems 鱼腥草茎和叶的表皮下有特殊的皮下层细胞,茎的皮层和髓中有分泌细胞存在。 |
| 4. | The results show that , from inner to outer , like oxya chinesis , the spermatheca of loxoblemmus doenitzi also consists of six layers except that there is only one kind of secretory cell in the epidermis 与中华稻蝗相似,受精囊由内向外也可分为六层,但上皮层仅有一种分泌细胞。 |
| 5. | Conclusions basal cell hyperplasia and tumors have different features of morpholoy and immunohistochemistry in constract to that of secretory cells , and based on these fertures 6 types were categorized 结论基底细胞增生和肿瘤具有与分泌细胞不同的形态学和免疫组化反应特征,其特征可表现为6型。 |
| 6. | It can be concluded from the results that c - myc plays an important role in regulatin g the related genes in meiosis of spermatomeres and spermiogenesis and in regulating the secretion of the secretory cells in the spermatheca 从实验结果看, myc蛋白可能在减数分裂中激活相关基因,尤其是在精细胞形成早期可能参与了精细胞内大量的基因转录,还可能参与了受精囊囊壁上皮细胞的分泌活动。 |
| 7. | Each type of hormone secretory cells is adjusted directly by the nerve fibre in the pituitary . the nerve secretory fibre can be divided into types of a1 , a2 and b . the nerve fibre forms synaptic or indirect links with special harmone secretory cells 根据其轴突内分泌颗粒的大小和形状,鲇神经分泌纤维可区分为a _ 1 、 a _ 2 、和b三种类型,不同类型的神经分泌纤维分别与特定激素分泌细胞形成突触联系或其他间接联系形式。 |
| 8. | The results indicated that ( 1 ) " longxianhuosuan " presented more regular and more densely - arranged epidermal cells in its scapes than " gailiangsuan " ; ( 2 ) " longxianhuosuan " showed a lower stomata number but a larger stomatal aperture in its scape surface than " gailiangsuan " ; its scapes had a great number of secretory cells , which had a larger size and appeared earlier ; its scapes presented a smaller number of vascular bundles with smaller diameters ( 3 ) " longxianhuosuan " had polygonal cells in its scape pith with their intercellular space occupying a small proportion while " gailiangsuan " showed elliptical cells in its scape pith with their intercellular space occupying a high proportion 结果表明: ( 1 ) “陇县火蒜”比“改良蒜”蒜薹的表皮细胞形状规则,排列致密;角质层较薄; ( 2 ) “陇县火蒜”比“改良蒜”蒜薹表面的气孔数量少,但开张度大;分泌细胞出现早、体积大、数量多;维管束数量少、直径小; ( 3 ) “陇县火蒜”蒜薹髓细胞卫多边形,髓细胞间隙率小,而“改良蒜”蒜薹的髓细胞呈椭圆形,髓细胞间隙率大。 |
| 9. | However , kit protein doesn " t exist in oogenesis after birth . there are also c - myc positive protein granules in the spermatomeres from metaphase i to telophase ii , in the spermatozoa and in the secretory cells of the spermatheca . c - myc protein expresses not in the normal follicles , but in the follicular cells of the apoptotic ones Myc在处于减数分裂的中期至末期的精母细胞的细胞质或细胞核内呈阳性表达,在减数分裂后形成的精细胞和受精囊囊壁的上皮细胞的细胞质内也有阳性表达:但在出生后的卵子正常发生过程中无阳性表达,然而在凋亡卵泡的滤泡细胞的细胞质内有阳性表达。 |
| 10. | Both upper and lower epidermis cells are polygonal or irregular in shape in all species studied . the patterns of anticlinal walls are straight , arched or sinuous , and the raphal cuticular striastriae are occasionally observed on periclinal walls . stomatal apparatus and secretory cells are found on the upper epidermis of several species and on the lower epidermis of all species 结果表明:这些植物叶片的上、下表皮细胞呈多边形或不规则形,垂周壁式样为平直、弓形或波浪状,平周壁偶有脊状条纹;少数种类上表皮还有气孔器或分泌细胞,所有种类下表皮具气孔器和分泌细胞;气孔器类型以平列型和侧列型居多,偶尔有无规则型;气孔极区呈稍角质加厚或棒状加厚,稀t形加厚。 |
