Abstract:
Objective To evaluate the effect of oxycodone pretreatment on oxygen-glucose deprivation and restoration (OGD/R)-induced injury to small intestinal epithelial cells of rats and the role of different opioid receptors.Methods IEC-6 cells were divided into 5 groups (n=15 each) using a random number table:control group (group C),group OGD/R,oxycodone group (group O),μ opioid receptor antagonist CTOP plus oxycodone group (group CTOP+O) and κ opioid receptor antagonist BNI plus oxycodone group (group BNI+O).Cells were cultured for 8 h in normal culture atmosphere in group C.Cells were subjected to OGD for 4 h followed by restoration of oxygen-glucose supply in normal culture medium for 4 h in OGD/R,O,CTOP+O and BNI+O groups.Oxycodone at a final concentration of 1 μg/ml was added at 5 min before OGD/R in O,CTOP+O and BNI+O groups.CTOP and BNI at a final concentration of 5 μmol/L were added at 10 min before OGD/R in group CTOP+O and group BNI+O,respectively.Five holes in each group were selected at 8 h of OGD/R for determination of the cell viability (by MTT assay),lactic dehydrogenase (LDH) release rate (by colorimetry) and levels of tumor necrosis factor-alpha (TNF-α),interleukin-1beta (IL-1β) and high-mobility group box 1 protein (HMGB1) in supernatant (by enzyme-linked immunosorbent assay).Results Compared with group C,the cell viability was significantly decreased,and the LDH release rate and levels of TNF-α,IL-1β and HMGB1 were increased in OGD/R,O,CTOP+Oand BNI+ O groups (P＜ 0.05).Compared with group OGD/R,the cell viability was significantly increased,and the LDH release rate and levels of TNF-o,IL-1β and HMGB1 were decreased in group O (P＜0.05).Compared with group O,the cell viability was significantly decreased,and the LDH release rate and levels of TNF-α,IL-1β and HMGB1 were increased in CTOP+O and BNI+O groups (P＜0.05).Conclusion Oxycodone pretreatment can mitigate OGD/R-induced injury to small intestinal epithelial cells of rats and the mechanism is related to activating μ and κ opioid receptors.
