What the authors concluded

Five different groups of Wistar rats were submitted or not to a daily dose of fish oil or/and laser sessions for 2 months. The ischemia volume was evaluated by stereology; GFAP, Iba, and NeuN by immunohistochemistry; TNF-α, IL-1β, IL-6, IL-10, and TGF-β by ELISA assay. " "PBM influenced both the lesion volume and the GFAP. Furthermore, PBM and Ω-3 or both reduced Iba RNAm. PBM reduced TNF-α, IL-
