Using the immunohistochemical technique, nerve cell bodies and fibres immunoreactive to the anti-Met-enkephalin sera were observed in the cerebral ganglia, pedal ganglia, visceral ganglia, inspect ganglia and coat ganglia of Octopus ocellatus. Met-ENK immunoreactivity was also localized in the mouth, esophagus, craw, stomach, stomachic caecus, the epithelium of the intestines, rectum, sialoid gland, liver, branchia, branchia gland, ventricle, branchial heart, kidneys, ovary, fallopian tube, back of mantle, abdomen of mantle, wrist, membrane of wrist, funnel, and immunocytes of Octopus ocellatus.

免疫组织化学定位结果表明：(1)在短蛸的脑神经节、足神经节、脏神经节、视神经节、外套神经节、口球、食道、嗉囊、胃、胃盲囊、肠、直肠、前唾液腺、后唾液腺、肝胰脏、鳃、鳃腺、心室、鳃心、肾静脉腺质附属物、卵巢、输卵管腺、外套膜背面、外套膜腹面、腕、腕间膜、漏斗中检测到呈不同阳性反应的Met-ENK分子。

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。

Positive cells were only seen in the oesophague of freshwater pomfret.

在鱼类的后鳃腺中相继发现这种激素的存在。

Taking all together, we proposed a energy metabolism model in gill epithelial cells during SW acclimation: The tricarboxylic acid cycle in MR cells is stimulated to produce enormous amount of energy for maintaining homeostasis and ion regulation at the 1st h after transfer to SW.

藉由上述结果，我们认为在鱼类适应不同盐度过程中，其鳃上皮细胞能量代谢的机制如下：当鱼类转移到海水后1st h时，其鳃上的MR cells会进入柠檬酸循环以产生大量的能量给MR cells。

At day 20, some of the acini collapsed, and the epithelial cells of the duct were damaged.

由10μg·L-1 B\P处理20d时，在鳃回血管中发现血细胞坏死后残留的固缩细胞核，鳃丝的上皮细胞排列不规则甚至断裂，部分消化腺泡崩解，鳃丝结构和消化导管上皮结构损害严重；消化盲囊组织结构的损伤比鳃更为严重。

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。

In this "five-step", the evolution of the first step in the series of groups of animals very strange: 14 more haikou insect specimens comparative anatomy studies show that, they not only, and the lack of chordomas in skin, muscle, breathing, circulation, neural organs such as the system with the fundamental difference between the existing chordates, One of the most distinctive is the gills of six foreign composed of respiratory system, and this is the mouth of higher animals in the gills.

在这分&五步走&的演化系列中，&第一步&的动物类群十分奇特：对1400多枚海口虫标本进行比较解剖学研究表明，它们不仅缺少脊索构造，而且在皮肤、肌肉、呼吸、循环、神经等器官系统上与脊索动物存在着根本差别；其中最为独特的是其由6对外鳃组成的呼吸系统，这与较为高等的后口动物的勤鳃迥然有别。

The activity of SOD in grass carp＇s liver and kidney tissues decreases first then increases and decreases once again when Cd^2＋ presents low concentration pollution, while the activity of SOD is inhibited obvious all along （p〈 0.05） when Cd^2＋ presents high concentration pollution.

Cd^2＋低浓度时，肝胰脏和肾脏组织SOD活性均为&先降后升再降&，而Cd^2＋为高浓度时SOD活性始终处于被显著抑制（P〈0.05）；鳃组织在低Cd^2＋污染时SOD活性为&先降后升&，而高浓度的Cd^2＋污染时其SOD活性为&先降后升再降&。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
