半鳃

The deduced amino acid sequence of red sea bream MHC classⅡB 1(Chma-DAB*0101) had 87.1%,85.1%,87.1%,90.4%,87.1%,90.8% identity with those of red sea bream classⅡB 2, 3, 4, 5, 6, 7(Chma-DAB*0201-Chma-DAB*0701), respectively, and had 75.2%, 74.5%, 55.9%, 55.1%, 34.3% and 30.4 % identity with those of striped sea bass, cichlid, rainbow trout, Atlantic salmon, mouse and human, respectively.

以正常鱼和鳗弧菌感染后真鲷组织为材料，以反转录合成的第一链cDNA为模板，应用RT-PCR半定量检测方法对真鲷的MHCⅡB基因组织表达特点进行了研究，结果表明，在正常真鲷组织中，其中较强的表达于鳃、脾、头肾、肾、胃、小肠和心脏中，在肌肉和血中表达最弱。

Built to feed exclusively on corals like this spindly gorgonian, a translucent 1.7-inch-long (4.3-centimeter-long) Phyllodesmium iriomotense houses its branching digestive gland within tentacle-like cerata—outgrowths the animal can shed if under attack.

建立供养独占的在珊瑚上像这个细长的柳珊瑚，一种半透明的1.7英寸长（4.3厘米长）Phyllodesmium iriomotense房子它的分支消化腺在触须里面-像露鳃-自然结果这动物能流出液体假如受到攻击。

建造供养仅仅专门地在珊瑚像这样细长的可怕的，一个半透明的1.7英寸长（4.3厘米长）Phyllodesmium iriomotense房子它的分支消化腺在触须里面-喜欢露鳃—自然结果这动物能射出液体假如受到攻击。

以细长的珊瑚为食物，一只长1.7英寸（4.3厘米）半透明的 Phyllodesmium iriomotense 就像那些断肢求生动物一样，如果受到攻击的话，它的枝状消化腺会收回到触手形的裸鳃中。

The result shew, Chromatin broke into pieces which dispersed around the irregular nucleus, nuclear outer member disintegrated; Mitochondria condensed, cristae of which disintegrated partly; The endoplasmic reticulum dilated, vesiculated, gradually disintegrated; A great number of dense granules appeared in the cell. To sum up: Enrichment of heavy metals in Eriocheir sinensis, Macrobrachium nipponease, Cipangopaludina cathayensis is obviou""

综上所述：我们首次证明上海地区沼虾、河蟹、园田螺对重金属元素富集能力要明显强于淡水鱼类；肝、鳃是鱼、虾、蟹体内重金属富集的主要部位；Hg和Cr为高富集元素，Cd是中富集元素，Cu和Pb为低富集元素；罗氏沼虾对镉离子和锌离子的96小时的半致死浓度（LC50）分别为0.115mg/L和0.68mg/L；首次证明锌离子、GSH在一定范围内可以抵抗镉离子对罗氏沼虾肝胰脏破坏。

Into the branchial artery to enter the blood with CO2 and more gill spacing, in the gills into the two sub-intervals of each one and a half gills, each issued a number of fine branches into the gill pieces, each small branch small piece of gill capillary network formed.

入鳃动脉将含CO2多的血液输入鳃间隔，在鳃间隔上分两支进入每个半鳃，每支发出若干细支进入鳃片，每细支的鳃小片上形成毛细血管网。

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。
