组织形态学

The present study is designed to seek the evidences of regeneration of auditory epithelia and acoustic nerve in the postnatal chick, By using the methods of tissue cultures, scanning electron microscopy, autoradiography and the cell image analysis technique, we observed the regeneration of auditory hair cell after intense sound exposure, and also neuron repair following a mechanical injury with either in vivo or in vitro.

本研究应用物理性噪声，建立了内耳听器-基底乳头声损伤的模型和初级听神经元纤维机械损伤的模型。在此基础上应用体外组织细胞培养、扫描电镜、放射自显影、光镜以及细胞图象分析等多种形态学方法，综合分析了听觉毛细胞和初级神经元轴突的再生反应。

Methods; 24 Sprague-Dawley rats were randomly divided into 3 groups; normal control group, LIR model group, and LW+HS treatment group. Pathologic changes of pulmonary tissue were observed. Lung tissue wet mass/dry mass weight ratio, tumor necrosis factor-α contents, myeloperoxidase activities, malondialdehyde contents were measured respectively.

将SD大鼠24只随机分为3组：正常时照组、模型对照组、模型＋高渗盐水处理组，分别行肺的病理形态学观察；批量检测肺组织湿重／干重比值、肿瘤坏死因子－α、含量、髓过氧化物酶活性、丙二醛MDA）含量。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
