[Abstract]  The formalin test was originally developed by Dubuisson and Dennis (1977), and has since been extensively used to assess pain-related responses. Rats and mice are the most frequently used animal models, though other species including cats, rabbits, guinea pigs, Octodon degus, domestic fowls, crocodiles, tortoises, toads and primates have also been employed. The injection of formalin into the skin of rodent hindpaws to cause spontaneous pain-related flinch behaviors is the most commonly used procedure. The resulting nociceptive response can be divided into two phases differing in timing, duration and underlying mechanisms, and is responsive to many classes of analgesic drugs (Coderre et al., 1990; Hunskaar and Hole, 1987; Rosland et al., 1990; Taylor et al. ... [摘要]  福尔马林试验最初由Dubuisson和Dennis(1977)开发,此后被广泛用于评估疼痛相关的反应。大鼠和小鼠是最常用的动物模型,但其他物种,包括猫,兔,豚鼠,八达冬,家禽,鳄鱼,龟,蟾蜍和灵长目动物也被使用。将福尔马林注射到啮齿动物后爪皮肤中引起自发性疼痛相关的退缩行为是最常用的手术。所产生的伤害感受反应可以分为时间,持续时间和潜在机制不同的两个阶段,并且对许多类别的止痛药有反应(Coderre等,1990; Hunskaar和Hole,1987; Rosland等,1990; Taylor et al。,1995)。对福尔马林的行为和电生理反应由短期持续反应的急性期(I期)组成,据信其反映C纤维传入伤害感受器的活性。在短暂的静止期后,急性期之后是连续延长的反应(II期),这被认为是由于脊髓背角神经元的中枢致敏引起的,因为来自C纤维伤害感受器的输入的初始阻塞早期阶段的传入(Coderre等,1993; Dickenson和Sullivan,1987; Raboisson等,1995; Shibata等,1989)。在这方面,福尔马林试验被认为是一种更加令人满意的疼痛模型,而不是产生诸如热板和尾部轻弹试验之类的阶段性疼痛的试验(Abbott等,1981)。在这里,我们描述了在大鼠和小鼠中产生有效和可重复的福尔马林试验的程序。
