In the normal group, electron microscopy showed normal chondrocytes were oval, and cells and cell membrane were intact. In cytoplasm, there were abundant rough endoplasmic reticulum, dictyosome, and mitochondria with intact nucleus, and even chromatin. In the model group, chondrocytes exhibited obvious pyknosis and their shape was irregular. The areolae around cells disappeared; cell organs in cytoplasm coagulated to flaps which showed electron dense and was uneasy to observe; the shape of nucleus showed irregularity, and caryotin gathered densely.

电镜下正常对照组软骨细胞呈椭圆形，细胞及胞膜完整，包质内可见丰富的粗面内质网、高尔基体、线粒体，细胞核完整，染色质分布均匀；模型对照组软骨细胞明显固缩且外形不规则，细胞周晕消失，胞浆内细胞器凝成高电子密度的片状物不易分辨，细胞核不规则，染色质浓聚，散裂于核中。

At early stage after brain injury, there were a quantity of fibrous callus and cartilaginous callus formation in brain injury and fracture group and many neuropeptides immunoreactive nerve fibers in callus were found. Strong immunoreactivites of CGRP, SP, VIP, NPY, TOH occurred to osteogenitor cells and chondroblast, which proliferated in thickened endothecium.
