hematological changes in opium addicted diabetic rats

objectives the aim of this study was to evaluate the biological effects of opium on the number of peripheral blood cells and red blood cells (rbcs) indices in diabetic rats. materials and methods peripheral blood samples were collected from diabetic, opium-addicted, diabetic opium-addicted and normal male and female rats and hematological parameters were measured. results the mean number of white blood cells (wbcs) was significantly higher in diabetic opium-addict females compared to diabetic non-addict female group. in both male and female, the mean number of neutrophils was significantly higher and the mean number of lymphocytes was lower in diabetic opium-addicted rats than those observed in diabetic non-addicted group. in diabetic opium-addicted male group the mean counts of rbc significantly increased as compared with diabetic male group. however, in diabetic addicted female, the mean number of rbcs was significantly lower than diabetic non-addicted female group. in both males and females, the mean number of platelets was significantly lower in diabetic addict rats compared to diabetic non-addict group. conclusions generally, the results indicated that opium addiction has different effects on male and female rats according to the number of wbc, rbc and rbc indices. it could also be concluded that in the opium-addicts the risk of infection is enhanced due to the weakness of immune system as a result of the imbalance effect of opium on the immune cells. background chronic opioid treatment in animal models has shown to alter hematological parameters.
