本文在研究中国水牛鼻唇腺微细胞结构的基础上,应用三例老龄水牛鼻唇腺的材料,通过电镜技术,观察了腺细胞和部分导管的亚微结构。鼻唇腺腺细胞呈锥体形,游离面具短小而稀疏的微绒毛,胞核位近细胞的基底部,明显有内外两层核膜,核仁1～2个,糙面内质网明显,其间夹有长形线粒体。细胞分泌区具明显的高尔基器,并有大量外包界膜的分泌颗粒。分泌颗粒可分三种类型:第一种类型是体积大小不同、电子致密度不等的分泌颗粒,根据其电子致密度的不同可再分为四种类型;第二种类型是体积大小相近、电子致密度近乎一致的分泌颗粒;第三种类型是具有致密心或致密心偏位的分泌颗粒。腺细胞间存在明显的细胞间分泌小管。闰管细胞的特征是含有少量糙面内质网,少量微绒毛,胞质内有十字交叉排列的张力微丝束,细胞侧膜分布有多重桥柱。分泌管细胞存在明暗两种类型,其主要特征是基部质膜大量内褶,与相邻细胞形成指状相嵌,褶内有大量线粒体。
Based on the study of the nasolabial gland microcephalus structure of buffalo in China, three sub-microtissues of glandular cells and some catheters were observed by electron microscopy. The nasolabial gland cells are pyramidal in shape with short and sparse microvilli of free facets. The basal part of the cell near the nucleus is obviously with inner and outer two layers of nuclear membrane with 1-2 nucleoli. The rough endoplasmic reticulum is obvious There are long shaped mitochondria. Cell secretory region with obvious Golgi device, and a large number of secretomes secreted particles. Secreted particles can be divided into three types: The first type is the size of the different electron density of secreted particles, according to their different electronic density can be further divided into four types; the second type is similar in size, Nearly uniform electron density of secretory granules; the third type is dense granules or dense centrilobular secretory granules. Gland cells have obvious intercellular secretory tubules. Intercalated ductal cells are characterized by a small amount of rough endoplasmic reticulum, a small amount of microvilli, the cytoplasm of cross-arranged tension microfilament bundle, the cell membrane distribution of multiple pillars. There are two types of secretory tube light and shade, its main feature is the base of a large number of plastids within the placenta, adjacent to the formation of finger-like phase of the cell, pleated with a large number of mitochondria.
