Abstract
Purpose:
To evaluate the protective effect of dexmedetomidine on gastric injury
induced by ischemia reperfusion (I/R) in rats.
Methods:
A total of 18 male albino Wistar rats were divided groups as: gastric
ischemia reperfusion (GIR), gastric ischemia reperfusion and 50 μg/kg
dexmedetomidine (DGIR) and sham operation (HG) group. After the third hour
of reperfusion, the biochemical and histopathological examinations were
performed on the removed stomach tissue.
Results:
Malondialdehyde (MDA) and myeloperoxidase (MPO) levels were found to be
significantly higher in GIR compared to HG (p < 0.05). A statistically
significant decrease was observed at the DGIR compared to the GIR for
oxidants levels. Total glutathione (tGSH) and superoxide dismutase (SOD)
levels were statistically significantly decreased at the GIR, and
antioxidants levels were found to be significantly higher in the DGIR (p
< 0.05) There was no significant difference between HG and DGIR in terms
of SOD (p = 0.097). The DGIRs’ epitheliums, glands and vascular structures
were close to normal histological formation.
Conclusions:
Dexmedetomidine is found to prevent oxidative damage on the stomach by
increasing the antioxidant effect. These results indicate that
dexmedetomidine may be useful in the treatment of
ischemia-reperfusion-related gastric damage.
