response latency

Result: ① Characteristics of nerve conduction: 94.7% patients had abnormal motor nerve conduction with decreased CMAP amplitude, prolonged distal motor latency ( DML) and absent response.

结果：①神经传导特征：94.7%患者运动传导异常，表现为单纯复合肌肉动作电位（CMAP）波幅降低、波幅降低伴潜伏期延长、动作电位缺失三种类型；

Six hours after the last injection, the jumping response times in 30 minutes, jumping latency in 1 hour before and after withdrawal reaction, straight, body stretch, loss of body mass, diarrhea and other symptoms were observed.

于末次注射吗啡后6h观察各组小鼠30min内跳跃反应次数、戒断反应前后1h内跳跃潜伏期、直立、躯体拉伸、体质量丧失量及腹泻等症状。
