| Abstract | Oncological pain is one of the most prevalent and difficult-to-treat symptoms in patients with cancer. p-Cymene (PC) is a monoterpene found in more than 100 different plant species, endowed with various pharmacological properties-particularly antinociceptive. Hypothesis/Purpose: PC has antinociceptive effect in a model of oncologic pain due to the activation of the
descending inhibitory pathway of pain.
Study Design: A pre-clinical, longitudinal, blind and randomized study.
Methods: Male Swiss mice were induced with S180 cells in the right hind paw, then treated daily with PC (12.5,
25 and 50 mg/kg, s.c.) and screened for mechanical hyperalgesia, spontaneous nociception, nociception induced
by non-noxious palpation, tumor growth, changes in the neuromuscular function and existence of bone degradation
in the tumor area. The effect of PC on Ca2+ currents (electrophysiological records), histological and
neurochemical changes (immunofluorescence for Fos) were also evaluated.
Results: PC reduced (p < 0.05) the mechanical hyperalgesia, the spontaneous (p < 0.001) and non-noxious
palpation (p < 0.001) nociceptions, not changing the tumor development, neuromuscular function or histopathological
aspects of the paw affected. PC reduced Fos expression in the spinal cord (p< 0.001) and increased
this expression in the PAG (p < 0.05) and in the NRM (p < 0.01). PC decreased the density of calcium channel
currents (p < 0.05).
Conclusion: These results suggest the antinociceptive effect of PC on oncologic pain, probably acting in both
ascending and descending pain pathways, and modulating the calcium channel currents in order to exert its
effects. | pt_BR |
