The homologous analysis showed that the identity between AVA and Galanthus nivalis agglutinin, Narcissus hybrid cultivar agglutinin, Lycoris radiata agglutinin, Clivia miniata agglutinin are 73.4％, 85.3％, 80.7％, 83.5％,respectively. Molecular modeling of AVA indicated that its three-dimensional structure strongly resembles that of the snowdrop agglutinin. Blocks' analysis revealed that the deduced amino acid sequence of AVA has three functional domains specific for agglutination and three carbohydrate-binding boxes.

Biological characterization results showed that all NDV isolates could form round and clear plaques on the monolayer cell of chicken embryonate fibrocytes; MDT are between 36.8 hours and 73.6 hours; ICPI are between 1.51and 2.00, belong to velogenic NDV.

所有毒株均可较好地凝集鸡和人的红细胞，但对其它动物的红细胞凝集性差异较大，对马和兔的红细胞凝集无规律。

Four field strains of infectious bronchitis viruswere isolated from chicken kidney, trachea and lung of the young layer flocks in some regions of Shaanxi province. Biological characterizations of the virus were investigated by virus pathogenicity to chicken embryo and healthy chickens, hemagglutination test, hemagglutination inhibition test, dwarfing embryonated chicken eggs, electron microscopy and reverse transcription polymerase chain reaction. It demonstrated that allantoic fluid of each passage virus could hemagglutinate chicken red blood cells by treatment with 1% trypsin. The standard positive serum to IBV could inhibited the hemagglutination. The isolates could make respiratory and kidney diseases in chickens.

采集陕西省宝鸡市、扶风县、兴平市和榆林市等地鸡场疑似传染性支气管炎发病鸡病料，通过9～11 日龄非免疫鸡胚进行了病毒的实验室分离和传代，并对分离毒株进行了病毒的血凝性、血凝抑制性、致病性、鸡胚矮小化、电镜特征等生物学特性鉴定，结果表明，4 株分离株经1%胰酶处理后的各代病毒尿囊液均可凝集鸡红细胞，标准阳性血清可特异性的抑制其凝集性，回归试验可复制出与自然发病相同的病例，病毒传代物有明显的致鸡胚矮小化作用，透射电镜下可见有近似球形、直径100 nm左右的冠状病毒粒子，将分离鉴定的4 株IBV 定名为BJ-04、FF-04、XP-03 和YL-04。

As the first attempt, it was designed to reveal the general pattern of lectin receptor distribution on the surface of female cells, namely egg cells, central cells and synergids of Torenia fournieri and, especially, toensure the possible effects of cell isolation procedure on the distribution of lectin receptors by four different systems.
