Title

The effect of alpha linolenic acid on tracheal responsiveness, lung inflammation, and immune markers in sensitized rats

Pages

  255-261

Abstract

 Objective(s): The effects of Alpha linolenic acid (ALA) on Tracheal responsiveness (TR), total protein (TP), phospholipase A2 (PLA2), immunoglobulin E (IgE), interleukin 4 (IL-4), interferon gamma (INF-γ ) level and INF-γ /IL4 ratio in bronchoalveolar lavage fluid (BALF) of Sensitized rats were examined. Materials and Methods: TR to methacholine and ovalbumin (OA), BALF levels of TP, PLA2 and IgE as well as IL-4, INF-γ and INF-γ /IL4 ratio were measured in control group (non-sensitized, group C), Sensitized rats to OA (group S), S groups treated with two concentrations of ALA and dexamethasone group. Results: TR to methacholine and OA, BALF levels of TP, PLA2, IgE and IL-4 were significantly increased but BALF level of INF-γ and INF-γ /IL4 ratio decreased in group S compared to group C (P<0. 001 for all cases). Treated S groups with dexamethasone and both concentrations of ALA lead to significant decrease in TR to methacholine and OA, BALF levels of TP, PLA2, IgE and IL-4 compared to group S (P<0. 001 for all case). The effects of all concentrations of ALA on INF-γ , IL-4 and INF-γ /IL4 ratio and also the effect of its highest concentration on TP and IgE level were significantly higher than dexamethasone treatment (P<0. 001 for all cases). Conclusion: Results showed an immune modulatory effect of the ALA that increased INF-γ , INF-γ / IL4 ratio (as an index of Th1/Th2) and decreased IL-4 in Sensitized rats. ALA also showed preventive effect on Inflammatory markers and Tracheal responsiveness in sensitized animals comparable to the effect of dexamethasone.
