Fig. 3From: Protective effects of thalidomide on pulmonary injuries in a rat model of paraquat intoxicationEffects of thalidomide on expression levels of IL-6, TNF-α, TGF-β1 and COL1A1 in lung tissues after PQ intoxication. Lung tissues from each treatment group were excised on day 15 after PQ administration and mRNA expression levels of IL-6, TNF-α, TGF-β1 and COL1A1 genes were examined using RT-PCRBack to article page
