Hemagglutination activity of lectin samples after treated under different condition was tested, and its stability was evaluated; and agglutinating effect to the microalgae cells and microorganism were observed by an inverted microscope.

方法］测定经各种条件处理过的鳙鳃凝集素样品的血凝活性，评价其稳定性；通过镜检测定鳙鳃凝集素对微藻细胞及各种微生物细胞的凝集作用。

Then the difference of these lamellae in the histology and morphology were observed in light microscopy.

利用光镜研究怀卵期外鳃小瓣与非怀卵期鳃小瓣在组织学和形态学上的不同点。

The injured gill cells had a different ultrastructure, with endoplasmic reticulum dilated and vesiculated, mitochondrial cristaes partially disintegrated, gill fibre cuticles denatured and dropped. The ultrastructural damages to hepatopancreatic cells were characterized by the decrease of microvilli, swelling and breaking up of mitochondria, expansion of endoplasmic reticulum, disruption and vacuolization of nucleus, tumefaction of nuclear membrane and increase of lipid droplets. As for the toxicological changes of myocardial cells, the mitochondria were swelling, having a lot of vacuolus and disintegrating, while the myofibrils were irregular with endoplasmic reticulum dissolved.

鳃细胞的损害表现为鳃丝水肿，细胞器溶解，角质层变薄，线粒体、内质网的肿胀、解体；肝胰脏细胞的主要损害特征为肝管微绒毛减少，线粒体水肿解体，内质网扩张，细胞核空泡化，核膜水肿和脂肪滴增加；心脏细胞的毒理变化为线粒体内嵴肿胀、瓦解，肌原纤维不规则，内质网溶解。

Gill blood circulation on the gill respiratory protection.

鳃上的血液循环是鳃呼吸的保障。

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。

The result showed the crude extract of castor-oil plant leaves contains some active substances which are attractive to Holotrichia oblita.

金龟甲的取食反应在华北大黑鳃金龟、铜绿丽金龟、暗黑鳃金龟对不同植物叶片的取食反应试验中，3种金龟甲对蓖麻叶的取食量均最小。

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。

Based on this, four DBP concentrations(0.38, 0.85, 1.90, 4.25mg·L-1)were confected using the same distance of logarithmic distance, and 20 days' sub-acute toxicity test was carried out. The weights of the liver and gill of B. rerio were measured every 5 days.

在此基础上，等对数浓度差设置4个质量浓度0.38、0.85、1.90、4.25mg·L-1进行20d慢性染毒，期间每5d测定斑马鱼的体重、肝重和鳃重，同时测定斑马鱼肝脏、鳃中SOD酶和ATPase活性。

The surface architecture and ultrastructure of gill filaments and secondary gill lamellaes of S. oramin and S. argus were similar to other teleosts. The gills from both S. oramin and S. argus showed regular and irregular circular microridges, indentations, micropits and crevices.

结果表明，黄斑篮子鱼和金钱鱼鳃的表面结构及微细结构与其他硬骨鱼类基本相似，鳃丝表面都具有规则或不规则分布的环形微嵴、沟、坑、孔等结构。
