【摘要】 本文以自制摆式胶锤打击器，一次性打击猫脑枕部，造成猫脑震荡的动物模型，并通过生理功能指标（EEG、ECG等）及组织学检验（HE、Nissle、Glees－Marsland染色），结果显示出脑震荡的病理学无明显的形态学变化，而脑损伤则有挫伤、出血、弥漫性神经元损伤等明显的病理形态学改变，从而提出了脑震荡与脑损伤的分界和诊断标准。更多还原

【Abstract】 Blunt btain trauma and brain concussion tend to happen in daily life, espetially, mild brain injury. In order to have a view of it, 18 cats were used for experiment in which the cat occipital was hit by artificial pendulum hammer to establish an animal model of mild brain injury and brain concussion.The results indicated that there were only reversible changes in physiological function (EEG, ECG) and reversible unconsciousness for a short while without obviously morphological changes following mild concussive blunt brain trauma suggesting the occurrence brain concussion. On the other hand, if the morphological changes occurred following mild brain trauma, they would belong to brain injury instead of brain concussion. Therefore, the pathological morphological changes and whether the changes in physiological functions (ie, EEG, ECG,Consciousness) reverse in a short while may separate concussive blunt brain trauma from brain concussion, which is very important to the forensic identification and clinicaI diagnosis.更多还原
