Radio-ligand binding assay was applied to determine the maximum binding and affinity changes of nicotinic acetylcholine receptor on five weeks old male Sprague-Dawley rat's lateral pterygoid muscle and superficial masseter muscle after the function mandibular advancement.

本研究在以往研究的基础上，首次对功能矫形的神经肌肉调控机理进行探索。应用放射受体分析法，从膜受体蛋白分子水平定量研究功能矫形前伸青春期SD大鼠（5周龄）下颌后，下颌前伸肌细胞膜烟碱样乙酰胆碱受体最大结合容量和亲和性的变化。

A virus strain was isolated from the arthrosis of broiler chickens.The virus was shown to have spherical particles with isometric symmetry,no envelope,double deck capsids,with outer capsid of 75nm,inner one of 50nm in diameter by electron microscopy.The virus was not sensitive to aether,acid and heat.The virus could multiply on the chick embryo fibroblastcell,and could cause syncytial pathologic change with the appearance of cytoplasm inclusion bodies.The challenged chickens of one-day old by nasal,oral,intramuscular and pulvillus injection displayed obvious clinical symptom of severe arthritis and accompanied with pathological changes of malabsorption and necrosis.Meanwhile,four avian reovirus isolates CL,S1133,YH and YB were examined in the cross-neutralization test.

从临床患病鸡关节病料中分离到一株病毒，在电镜下观察到病毒粒子无囊膜，有双层衣壳，外衣壳直径约75nm，内核约50nm；分离病毒株对酸、热有较强的抵抗力，对乙醚不敏感；病毒感染鸡胚成纤维细胞上能产生以融合细胞为特征的CPE；爪垫接种1日龄雏鸡表现出明显的病毒性关节炎临床症状，并伴有吸收障碍型和坏死型的病理变化；血清中和交叉试验表明，该病毒分离株与国内的2株番鸭源呼肠孤病毒分离株和国外S1133呈不同程度的交叉反应。
