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。

Upon a salinity challenge, euryhaline teleosts immediately regulate the functions of many ion transporters and enzymes in the gill mitochondria-rich cells for maintaining their internal homeostasis.

当广盐性鱼类面对环境盐度改变时，鱼类鳃上皮细胞许多位於富含粒线体细胞(mitochondria-rich cell， MR cell)的离子通道就必须及时运作以维持鱼体内的渗透压恒定，由於大多数的离子通道都是需要耗能的主动运输，故鳃是个需要大量能量的器官。

The ultrastructure of the gill surface in largemouth bass Micropterus salmoides and blue gill Lepomis macrochirus was investigated using scanning electron microscopy.

应用扫描电镜对大口黑鲈Micropterus solmoides和蓝鳃太阳鱼Lepomis macrochirus鳃的表面微细结构进行了观察。

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。

The first gill area of breastplate is light yellow , the gill Intermittently shows vacuolar.

头胸甲的鳃区呈淡黄色，鳃丝间断出现空泡。

It was showed that pectenolone and pectenoxanthin were all found in Gonads, hepatopancreas, mantle and gill, among of them, ovary, hepatopancreas and gill possessed more carotenoid than other tissues, but no carotenoids were found in the white muscles of Yesso scallops. Hepatopancreas contains a variety other carotenoids some kind of other not identified beside pectenolone and pectenoxanthin. The result also showed that the Yesso scallop with orange muscle had more the carotenoids in a variety of tissues than the common, and the female more than the male.4 Impacts of carotenoid accumulation on morphological structure and chemical composition in orange muscle of Yesso scallopThere was no difference between the orange and white muscle obserced by conventional HE staining, while musclular fiber type and matrix density in the orange muscle was different from white ones by the TEM observation of ultra-thin slices, and there were three musclular fiber types, among of them, the loose muscular fiber was orange muscle specifically.

利用HPLC法对橘红/白色闭壳肌虾夷扇贝各组织中含有的类胡萝卜素种类和含量，结果表明，虾夷扇贝在性腺、肝胰腺、外套膜、鳃丝中均含有类胡萝卜素pectenolone和pectenoxanthin，白色闭壳肌中未检测到类胡萝卜素，其中肝胰腺除上述两种类胡萝卜素外，还含有其他多种未鉴定的类胡萝卜素；在各组织中，雌性性腺、肝胰腺、鳃丝中类胡萝卜素的含量较高；橘红色闭壳肌虾夷扇贝各组织中的类胡萝卜素含量高于白色闭壳肌虾夷扇贝；雌性虾夷扇贝中的类胡萝卜素的含量高于雄性。4累积类胡萝卜素对虾夷扇贝闭壳肌的形态结构和化学成分的影响本文对橘红色闭壳肌进行了常规HE染色切片观察，并未观察到异常现象；超薄切片透射电镜观察发现橘红色闭壳肌在肌纤维类型及基质密度等方面有别于白色闭壳肌，在橘红色闭壳肌中有三种肌纤维，其中疏松型肌纤维为橘红色闭壳肌特有。

The results indicate that the thyroid gland of grey mullet is dispersedly distributed in the region of the arteria branchialis afferens of the first to the third pair of branchial arches. The monolayer follicle epithelial cells around a follicle were squamous shaped or cuboidal shaped, indicating an asynchrony of cellular activity in a follicle. The scale of the two shapes of cells differed significantly among developmental stages.

结果表明，鲻鱼甲状腺滤泡分散地分布在第1对至第3对鳃弓的入鳃动脉之间；构成同一滤泡的单层上皮细胞呈扁平形和立方形两种形态，反映出同一滤泡中上皮细胞生理活动的不同步，且发现不同发育时期的鲻鱼这两种形态细胞的比例有显著差异。
