  • Alteration in endogenous systems during chronic inflammatory pain conditions

    • The influence of chronic arthritic pain on two endogenous opioid peptides, dynorphin B and [Met5]enkephalin-Arg6-Phe7, and multiple opioid receptors in discrete brain, lumbar spinal cord and pituitary pools was investigated. Using radioimmunoassay and receptor binding assay, we examined the changes in regional opioid peptide levels and opioid receptor activity due to chronic inflammation in adjuvant arthritic rats. At 4 weeks post-inoculation, increased levels of immunoreactive dynorphin B and [Met5]enkephalin-Arg6-Phe7 were measured in tissues of arthritic rats compared with controls. No significant changes in mu-, delta- or kappa-opioid receptors were seen after chronic inflammation. Taken together, these results indicate that in chronic arthritis, opioid receptor changes do not follow the peptide alterations of pro-dynorphin and pro-enkephalin systems. Thus, dynamic modification and modulation of nociceptive information takes place during chronic inflammation. This supports the key role of the central nervous system in chronic inflammatory pain conditions.

  • Effects of electro-acupuncture on corticotropin-releasing factor in rats with experimentally-induced polycystic ovaries.
  • 2001
  • Ingår i: Neuropeptides. - : Elsevier BV. - 0143-4179. ; 35:5-6, s. 227-31
  • Tidskriftsartikel (refereegranskat)abstract
    • The aims of the present study were to investigate corticotropin-releasing factor (CRF) concentrations in the brain, the adrenal glands, and the ovaries in rats with estradiol valerate (EV) induced polycystic ovaries (PCO). The effect of 12 electro-acupuncture (EA) treatments on CRF concentrations was also investigated. The CRF concentrations in the median eminence (ME) were significantly increased in rats with PCO (both the PCO control group and the PCO group receiving EA) compared with the healthy control group (veichle control group), indicating increased activity in the hypothalamus-pituitary axis. The CRF concentrations in the ovaries were significantly reduced in the PCO group receiving EA compared with the PCO control group. Also, there was a decrease in comparison withthe healthy control group but the decrease was not as significant. This finding indicates that repeated EA treatments change the neuroendocrinological state in the ovaries, which may play an important role in reproductive failure.
