Abstract

The vocalization thresholds and latent periods of motile reaction have been studied in normal rats, at extremity trauma, and at intraperitoneal injection of an algogen [correction of allogene]. The dissociation of changes in pain sensitivity and motile reactivity in during, visceral and somatic pain conditions was observed. A strong hypoalgesia during visceral stimulation and hyperalgesia at trauma accompanied by inhibition of motile activity have been discussed from the point of view of their significance in defense reactions of the organism at pain conditions of various nature.

摘要

已经在正常大鼠、肢体创伤以及腹腔注射致痛剂[异体校正]的情况下,研究了发声阈值和运动反应的潜伏期。观察到在内脏和躯体疼痛状态下疼痛敏感性和运动反应性变化的分离现象。从它们在机体对各种性质疼痛状况的防御反应中的意义角度,讨论了内脏刺激时的强烈痛觉减退以及创伤时伴有运动活动抑制的痛觉过敏现象。
