前言 乳色斑(MS)也称Kampmeiers’s病灶,局部于体壁的小叶内并充当纵膈感染的屏障,具有非常重要的吞噬细胞功能。先前的研究弄清高强度/低频率的噪声暴露导致胸膜的间皮层发生形态功能变化。本研究的目的是调查MS的动力学变化,即在噪声的应激下感染因子达到胸膜腔的反应。材料与方法 Introduction Milk stains (MS), also known as Kampmeiers’s lesions, are localized in the parietal lobules and act as a barrier to mediastinal infection and have a very important phagocytic function. Previous studies have identified that high-intensity / low-frequency noise exposure leads to morphological changes in the pleura’s mesothelium. The purpose of this study was to investigate the kinetic changes of MS, that is, the response of the infectious agent to the pleural cavity under noise stress. Materials and Methods
