鳃丝

鳃丝中Na，Ca和Cl元素的含量总体上呈下降的趋势，在一定程度上说明与Ca2+、Na+和Cl-运转有关的酶的活性受到抑制。

The levels of Na , Ca and Cl in gill filament decreased along with the exposure time in general , indicating Na + / Ca 2 + ATPase activities were inhibited .

鳃丝表皮上有扁平上皮细胞、氯细胞、粘液细胞；

Epithelia , chlorine cells and mucilage cells were observed on the gill filament surface .

重金属离子对中华绒螯蟹肝胰脏和鳃丝SOD，CAT活力的影响

Effects of Heavy Metal Ions on SOD , CAT Activities of Hepatopancreas and Gill of the Crab Eriocheir sinensis

胁迫后，对照组血清T-SOD、鳃丝NKA活性显著降低，皮质醇含量显著增加（P0.05）。

After stressed , T-SOD and gill NKA activity in control group were significant decreased and cortisol content was significant increased ( P0.05 ) .

以初始体重7.004±0.14g的青鱼幼鱼为研究对象，研究氨氮胁迫对其鳃丝NKA、组织结构及血清部分生理生化指标的影响。

The object of this study was to evaluate the effects of ammonia on the gill NKA , microstructure and serum biochemical indices of juvenile black carp , Mylopharyngodon piceus .

结果表明：ALF主要表达并存在于血细胞中，在鳃丝小叶边缘微血腔、心肌束间隙、肝小管间隙以及肠壁边缘有阳性信号出现。

Immunohistochemistry results showed that the ALF existed mainly in hemocyte and positive signals were also found in blood vessel of gill , lacunaes among myocardial bundles of heart , hepatopancreatic tubules and blood sinus in connective tissues of intestine .

结果显示，NKA广泛分布于鳃丝和鳃小叶上，其中盐度组的NKA免疫阳性细胞数量显著多于淡水组，盐度组细胞的荧光强度大于淡水组。

The tests revealed that : NKA-positive cells were widely present in the filament and lamellae . The number and staining intensity of NKA-positive cells in salinity 10 group was more than that of fresh water group .

鳃丝表面有少量氯细胞。

There are a few chloride cells in the gill surface .

普通鳃丝的扁平细胞为呼吸上皮。

The flat cells in the ordinary gill filaments are respiratory epithelia .

鳃丝呼吸面上皮细胞薄，高度血管化，形成呼吸面隆起；

The respiratory surface of gill filament was rough and highly fulled of blood vessels ;

褐牙鲆鳃丝Na~+-K~+-ATPase性质的研究

Characterization of Gill Na ~ + - K ~ + - ATPase in Paralichthys olivaceus

在血淋巴、肝胰腺、心脏、鳃丝等器官组织内均可见细菌。

There can be seen bacteria in hemolymph , hepatopancreas , heart , gill and other organs .

3种重金属离子对中华绒螯蟹鳃丝Na~+-K~+-ATPase活性的影响

Effects of three heavy metal ions on Na ~ + - K ~ + - ATPase activity in gills of crab Eriocheir sinensis

前者的鳃丝和鳃小片上氯细胞的数量明显多于后者，两者细胞形态也存在差异；

The number of chloride cells of the gill filament and lamellar in the former is higher than in the latter , and the morphology of chloride cells of both fishes are different ;

病鱼体表黏液脱落，皮肤溃烂，有出血和炎性渗出物、烂鳃，鳃丝固有结构崩解，皮肤坏死。

The mucus of body surface was desquamated , the skin of eels in lesions was ulcerated , and having hemorrhaging and inflammatory exudation , the gill was rotten , the inherent structure of gill filaments collapsed , skin necrosis .

结果表明：鳃耙、鳃弓、鳃丝上皮细胞表面都有环形隆嵴、断续的短纹；

The results demonstrated that the external morphological structure of gill rakes , the gill arches and the gill filaments showed the presence of various features such as annular ridge and short lines .

扫描电镜观察，鳃表面密生纤毛，主鳃丝处形成沟，18～21条鳃丝形成一条状隆起。

Scanning electron microscopic observations show that cilia grows densely on the surface of gill . Gullis are located in the main filaments . 18 ~ 21 filaments form a ridge .

鳃腹缘形成食物沟，鳃丝上具有明显的侧纤毛、前纤毛和前侧纤毛，鳃丝表面可见大量入鳃小孔。

Ventral margin of gill forms food groove , and there are obvious lateral cilia , frontal cilia and anterolateral cilia on gill filament , and a great number of holes into the gills on the surface of gill filament .

乐果和三唑磷对缢蛏鳃显微结构的影响是：鳃丝变短，鳃丝间隔和基底膜结缔组织增生，鳃孔、血管腔堵塞；

The microstructure of gill was destroyed when exposed to dimethoate and triazophos . Symptoms included the shortening of branchial filament , hyperplasia of inter-filamentary junction and the basal membrane connective tissues , and the jam of water tube and blood tube .

鱼鳃主要由鳃弓、鳃耙、鳃丝、鳃小片组成。

The gills constitutes of gill arch , gill raker , gill filament , branch leaf .

鳃小片呈褶皱状，镶嵌排列在鳃丝两侧。

Many secondary gill lamellae arranged on two sides of each filament , and inlaid each other .

在沼虾鳃细胞内未发现Pb颗粒，但在鳃丝之间发现少量Pb颗粒吸附在鳃丝的表面。

No lead granule was found in the cells of gills , but a few of lead granules adsorbed on the surface of gill filaments among the gill filaments .
