“…Acetic acid produces nociception directly by stimulation of terminal nerves, and indirectly by leading to the release of endogenous mediators involved in pain modulation, including bradykinin, serotonin, histamine, prostaglandin, and others that cause the stimulation of nociceptive neurons and, consequently, pain induction [13,14]. Thus, this model could be used routinely as a screening method to identify compounds with antinociceptive activity potential because of this high sensitivity to drugs with antinociceptive action from different drug classes such as aspirin, antagonists of kinin receptors, and central-and peripheral-acting opioid analgesics [15,16].…”

“…5). The inhibition in croton oil-induced ear edema caused by these treatments could be associated with interference in factors that influence edema formation, such as tissue vascular flow and systemic blood pressure [15]. However, considering that EtEx was able to inhibit the pain reaction time only in the second phase of the formalin test (inflammatory pain), we consider that the inhibition of croton oil-induced ear edema is due to a anti-inflammatory activity of this extract, and that the isolated substance, especially in the blockage of prostaglandins synthesis, is important in edema and pain generation [21].…”

“…Thus, acetic acid is used widely to screen and study compounds for antinociceptive activity and is thought to be a suitable method (Collier et al, 1968). In the acetic acid-induced writhing test, the behavioral reaction can be blocked by drugs with analgesic activity similar to aspirin, antagonists of kinin receptors, and the central-and peripheral-acting opioid analgesics (Barber et al, 1994;Brignola et al, 1994;Siegmund et al, 1957;Smith et al, 1982;Steranka et al, 1987;Vacher et al, 1964).…”

“…Avaliação da atividade analgésica -contorções abdominais induzidas por ácido acético: Ácido acético a 1,2% v/v (10 ml/kg, i.p) foi usado como agente irritante 5,6 . As contorções abdominais seguidas de torções do tronco e extensão dos membros posteriores 7 , provocadas pelo ácido, foram contadas durante 30 minutos. Avaliação da atividade antiinflamatória -edema em orelhas induzido pelo óleo de Croton: 20 µl de solução de óleo de Croton (2,5%) dissolvido em acetona, aplicada na superfície da orelha direita foram usados como agente inflamatório.…”
