Study of Protective Effect of Nigella Sativa Nanocapsules on Tissue Pathology and IL-10 levels in Lung Tissues Exposed to NNK

  It is assumed that ketone derived from tobacco (NNK) which is the most important carcinogen in tobacco modulates alveolar macrophage mediator production, such as anti-inflammatory cytokine IL-10. The aims of this study were to investigate the effect of a Nigella sativa on tissue pathology and IL-10 levels in lung tissues exposed to NNK In this experimental study, 46 Wistar rats of supplement, supplement+NNK, NNK, solvent and control. NNK-induced groups received NNK subcutaneously one day per week at a rate of 12.5 mg per kg body weight. Supplemented groups also consumed Nigella sativa Nanocapsules for 12 weeks. Levels of IL-10 in homogenized lung tissue were measured by ELISA. To analyze the data; ANOVA and Tukey test were used at a significance level of p≤005. Exposure to NNK increased levels of IL-10 compared with the solvent group, although not statistically significant (p≥005). Meanwhile, a period of consumption of Nigella sativa Nanocapsules significantly increased levels of IL-10 in NNK + supplement and the supplement groups compared to NNK group (p=0.038, p=0.002; respectively). In addition, the effect of Nigella sativa Nanocapsules on IL-10 levels of lung tissue was shown that the levels of this variable were significantly higher than the solvent group (p=0.001). Generally it could be confirmed that consumption of Nigella sativa Nanocapsules plays an important role in the inhibition of inflammation induced by NNK via Increase of IL-10 activity.
