鳃下的

To investigate the stability of lectin from gill of bighead carp under various conditions and cell agglutinating activity.

［目的］为了探明鳙鳃凝集素在各种条件下的稳定性及其细胞凝集活性。

But he untied the harpoon rope from the bitt, passed it through the fish's gills and out his jaws, made a turn around his sword then passed the rope through t he other gill, made another turn around the bill and knotted the double rope and made it fast to the bitt in the bow.

他从系缆柱上解下鱼叉柄上的绳子，穿进鱼鳃，从嘴里拉出来，在它那剑似的长上颚上绕了一圈，然后穿过另一个鱼鳃，在剑嘴上绕了一圈，把这双股绳子挽了个结，紧系在船头的系缆柱上。

Microstructure and ultrastructure of the hypobranchial gland of Haliotis diversicolor have been studied by light and electron microscopy.

本文采用光镜和电镜方法，研究了杂色鲍鳃下腺的显微和亚显微结构。

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。

These numeric results explained the outside stimulates the experimental phenomenon of the lamprey below the circumstance.

这些数值结果解释了外界刺激情况下七鳃鳗的实验现象。

Result succinylation modified, trypsin hydrolysis, SDS and β-mercaptoethanol treatment greatly reduced lectin from gill of bighead carp; dimethyl sulfoxide, NaCl, tri fluoroacetic acid at a given treated concentration had no effect on its activity; lectin from gill of bighead carp agglutinated Haenatcoccus pluvialis, vibrio harveyi and Vibrioauguil larum specifically.

结果］琥珀酰化修饰、胰蛋白酶水解、SDS及β-巯基乙醇处理均使鳙鳃凝集素活性大大降低；在设定的处理浓度下，二甲基亚砜、NaCl及三氟乙酸对其活性没有影响；鳙鳃凝集素能专一地凝集雨生红球藻及哈维氏弧菌和鳗弧菌。

The results showed that the American shad fingerlings stopped opercular movement less than half an hour after anesthetia when the fish were exposed to concentration of MS-222 at 75mg/L, clove oil at 20mg/L and bezocaine at 40mg/L. The fish recovered to normal behaviors again after exposed in air for less than 10min when transferred into fresh water. The shad fingerlings had good anaesthesia for more than 12h at 20-30mg MS-222/L, 8-10mg/L clove oil and 20-30mg/L benzocaine. The anesthetic effects were enhanced at high water temperature and changed with fish sizes. Small fish were more easily in good anaesthesia than the bigger one in MS-222 while the opposite case was found in clove oil and in benzocaine.

麻醉试验结果表明：在较高麻醉浓度（MS-222为75mg/L以上，丁香油为20mg/L以上，苯唑卡因为40mg/L以上）下，鱼很快（30min内）停止鳃盖张合运动，且停止鳃盖运动的鱼在空气中暴露一定时间（10min内）后也能够复苏；在适宜的麻醉浓度（Ms-222为20~30mg/L，丁香油为8~10mg/L；苯唑卡因为20~30mg/L）下，鱼能够进入麻醉状态，且能保持很长时间(12h)；麻醉效果随着水温的升高而增强；在20mg/L MS-222麻醉剂下，小规格鱼较大规格鱼更容易进入麻醉状态，而在10mg/L丁香油和20mg/L苯唑卡因麻醉剂下，小规格鱼却难进入麻醉状态。

Concentrations of free copper and mucus and other parameters including pH and alkalinity of the gill microenvironment of Cyprinus carpio exposed to copper of various levels were determined using Playle's apparatus.

利用 Playle设计的装置测定了不同铜暴露水平下鲤鱼鳃部进出水中的游离铜离子浓度、粘液含量及有关参数。用MINTEQA2和单配位体模型联合的试算方法计算了不同形态铜含量以及鳃部粘液对铜的络合能力。

Its translucent gills, in the sunshine, will show yellow-green, Gill, after a pair of pectoral fins, and other fish are not the same as the surface is a fan-shaped fins, and swimming up and is like a dance butterfly.

它的鳃半透明的，在阳光的照耀下，会显出黄绿色，鳃后是一对胸鳍，与其它的鱼不一样的是鳍面是扇形的，游动起来仿佛是一只翩翩起舞的蝴蝶。
