| خلاصه مقاله | Introduction:
Inflammatory factors and Oxidative stress affect the opioid system. Celecoxib, is an anti-
inflammatory drug and crocin (saffron extract) as an herbal agent have antioxidant activity.
The aim of the present study was to investigate the effects of celecoxib and crocin in the
prevention of Morphine induced dependence in mice.
Materials and Methods:
Ten groups containing 9 male mice in weight group 20-30 gr were randomly selected and
received the regimens mentioned below once daily for 4 days.
1) Saline (10 ml/kg, ip) + Saline (10 ml/kg, ip)
2) Morphine (50 mg/kg, ip) + Saline (10 ml/kg, ip)
3) Morphine (50 mg/kg, ip) + tween80(5%w/v,10ml/kg, ip)
4,5,6) Morphine (50 mg/kg, ip) + crocin (100,200,400 mg/kg, ip)
7,8,9) Morphine (50 mg/kg, ip) + celecoxib (5,10,20 mg/kg, ip)
10) Morphine (50 mg/kg, ip) + crocin (100 mg/kg, ip) + celecoxib (5 mg/kg, ip)
To investigate the effect of drugs on Morphine dependency on day 4th ,2 hours after the
last dose of Morphine injection, Naloxone was injected and symptoms of withdrawal
syndrome (number of jumping and standing on feet) were recorded within half an hour in
each mice. Eventually to evaluate the effect of these drugs on pro-inflammatory cytokines,
blood samples from the heart of the animals were taken and tests for TNF-α were
performed.
Results:
The results showed that administration of celecoxib and crocin (100,200 mg/kg) before
daily injection of Morphine, didn’t decrease Morphine dependency. Significant difference
was not observed between (celecoxib or crocin) and morphine dependent groups |
