Under light microscope, on H-E stain section, four types cells can be distinguish: cells with weak basophilic fibrillar elements; cells with acidophilic granular substance; cells with strong basophilic fibrillar elements and ciliated cells. In the basal lamina region under gland epithelium, there are a few connective tissue; Surface view of the hypobranchial gland could be see by scanning electron microscope, there are cilia and different kinds of secretions distributed. Ultrastructure of the hypobranchial gland could be understand by transmission electron microscope, supporting cells, sensory cells and seven types gland cell were observed to form the glandular epithelium; cells with much rough endoplasmic reticulum,smooth muscle fiber and nerve endings were found beneath glandular epithelium, among basal lamina region.
光镜下H-E染色切片中腺上皮区仅可以区分出四种类型的细胞:弱嗜碱性纤维样细胞、强嗜碱性纤维样细胞、嗜酸性颗粒分泌细胞和纤毛细胞等;腺上皮下的基底膜区有少量结缔组织存在;扫描电镜下可以观察到鳃下腺表面的纤毛及腺细胞的分泌物等情况;透射电镜下观察到腺上皮中有支持细胞、感觉细胞和7种类型的腺细胞;近基底膜区观察到富含粗面内质网的细胞;基底膜间为薄层疏松结缔组织,内含肌细胞及神经末梢等结构。

This complex reaction was phenolic electronic substitution reaction, so reaction rate was related with the positive electricity of pro-electronic reagent, as well as the form of aromatic hydrocarbons. Rates of chlorination of phenol and 2-monochlorophenol were faster in alkaline water than that in weak acid water, so 2,4-dichlorophenol and 2,4,6-trichlorophenol formation concentrations increased with the reaction time.
该复合反应属于酚类电子取代反应,反应速率与亲电子试剂的阳电性以及芳香烃的形式有关,碱性水环境中氯取代苯酚和2-一氯酚的速率要快于在弱酸性水环境;随着pH的升高,2,4-DCP和2,4,6-TCP的生成浓度也不断增加。

But urushiol has a poor resistance to alkali because phenol hydroxyl of urushiol shows weak acidity. Meanwhile, inherent brittleness of urushiol has limited its development and application.
但是,由于漆酚的酚羟基显弱酸性,使得漆酚耐碱性较差;同时,漆酚清漆固有的脆性等也限制了其发展和应用。

The results indicated that AKP exist in all tissues and organs of Andrias davidianus, which were mainly 230 and 200 KD. Activity of AKP in different tissues and organs was different, and these were strongest in heart and weakest in eyes. In the same tissues and organs, two kinds of AKP activities were different.
结果表明,二十四种组织器官中都有碱性磷酸酶存在,其中230和200 KD的碱性磷酸酶占优势;不同组织器官的碱性磷酸酶活性有差异,心脏中活性最强,眼球中活性最弱;在同一组织中,230和200 KD的碱性磷酸酶活性也有差异。
