一、研究概况1.过去的研究:多半是造成动物脊髓的钝挫伤,损伤暴力以克一厘米计算,即打开椎管,硬脊膜不切开,把重量(以克为单位)放在距离脊髓一定的高度(以厘米为计算单位)使其下落造成脊髓损伤。研究者有 Black(以猴作实验)使用损伤暴力为350克厘米,造成脊髓轻度损伤。Osterholm 及 Mathews:(以猫作实验)使用损伤暴力为500克厘米,造成重度损伤。Dohrmann(以猴及狗作实验)使用损 I. Research Overview 1. Past research: Mostly cause blunt trauma to the spinal cord of animals. The damage is calculated in grams of centimeters, that is, the spinal canal is opened, the dura is not cut, and the weight (in grams) is placed in the distance. A certain height (in centimeters) of the spinal cord causes it to fall and cause spinal cord injury. Researchers had Black, an experimental monkey, who used 350 g of traumatic violence to cause mild spinal cord injury. Osterholm and Mathews: (using a cat as an experiment) used a traumatic violence of 500 grams centimeters, causing severe injuries. Dohrmann (experimental with monkeys and dogs)
