Impact of Opium Addiction on Levels of Pro- and Anti-inflammatory Cytokines after Surgery
Authors
Abstract:
Background: Opium addiction alters immune responses to stresses such as an injury due to changing the secretion of cytokines. The present study assessed the effect of opium addiction on the cytokines [tumor necrosis factor α (TNFα), interferon-γ (IFN-γ), interleukin-4 (IL-4), and IL-10] before and after laparotomy. Methods: Male rats were randomly divided into control and opium addicted (n = 20). Then, cytokines were measured before surgery, immediately after surgery (within 30-60 minutes) and 24 hours after surgery. Findings: IFN-γ was raised in an addicted group in three phases of the study as compared to that of the control group. IL-4 in opium addicted group decreased in two phases after surgery compared to the control group. IL-4 was lower after surgery in comparison to before surgery in the opium addicted group. The difference in IL-10 and TNFα levels was not statistically significant in the all groups measured in three phases of the investigation. Conclusion: The results revealed that opium addiction can increase plasma level of IFN-γ in rats and decrease plasma level of IL-4 after surgical stress. It seems that opium addicted rats are a more susceptible to increased inflammation.

Stress-related mucosal damage (SRMD) is a significant cause of morbidity and mortality in critically ill patients due to the gastrointestinal blood loss. Prophylaxis of SRMD with proton pump inhibitors or histamine-2 blockers has gained widespread use in intensive care units. Both demonstrated to be effective in reducing clinically significant bleedings, while PPIs has shown to exert some anti ...

Background: The levels of IL-13, IL-4, IL-1B, TNF-α and IL-10 alter in the colon of people with ulcerative colitis. previous studies, it was found that shilajit (asphaltum) was effective in the improvement of ulcerative colitis.we guessed that the shilajit has been able to improve the ulcerative colitis by affecting the amount of cytokines. Objective: The aim of the present study was to investi...
