1·Methods: Using spontaneous hypertensive rats (SHR) of different age in months as experiment models to observe the remodeling of myocardium mesenchyme by collagen in quality and quantity.
方法：采用不同月龄自发性高血压大鼠(SHR)为实验动物模型，从胶原定性和定量指标观察心肌间质重构。
2·Some researches have shown that BMP -2 is an important signal molecule in the interaction between the epithelium and mesenchyme during embryonic development.
已有研究显示BMP-2在胚胎发育中是上皮与间质相互作用的重要信号分子。
3·The changes, termed 'pathological airway remodeling', affect the epithelium, the underlying mesenchyme and the reciprocal trophic interactions that occur between these tissues.
的变化，被称为“病理气道重塑”，影响上皮细胞，底层间质和这些组织之间发生的相互营养的相互作用。
