WebThe chemical mediators responsible for tissue inflammation act on nociceptive nerve endings to lower neuronal excitation threshold and sensitize afferent firing rate leading to the development of allodynia and hyperalgesia, respectively. WebAnother effective approach in acute pain management is to lower the concentration of the chemical mediators. This is exemplified by application of cold after trauma. If the inciting lesion cannot be removed and if …

WebThe kinins are also important inflammatory mediators. The most important kinin is bradykinin, which increases vascular permeability and vasodilation and, importantly, activates phospholipase A 2 (PLA 2) to liberate arachidonic acid (AA). Bradykinin is also a major mediator involved in the pain response. WebChemical Mediators of Nociception. It is relatively easy to characterize the locus of actions of endogenous mediators that elicit a sensation of pain using the genetic approaches described earlier.

WebVisceral hypersensitivity is currently the most widely accepted mechanism responsible for abdominal pain. Inflammatory mediators are known to sensitise primary afferents and to recruit silent nociceptors. Recent evidence suggests that non-inflammatory mediators also have the potential to trigger visceral pain. This sequence of events may constitute part of …
