摘要: Riboflavin (vitamin B2) is an easily absorbed micronutrient with a key role in maintaining health humans and animals. It the central component of cofactors flavin adenine dinucleotide (FAD) mononucleotide (FMN) therefore required by all flavoproteins. also works as antioxidant scavenging free radicals. The present study was designed to evaluate effects riboflavin against acute lungs injury induced administration single intranasal dose (20 μg/rat) lipopolysaccharides (LPS) experimental rats. Administration LPS resulted marked increase malondialdehyde (MDA) level (p < 0.01) MPO activity (p < 0.001), whereas decrease glutathione (GSH) content reductase (GR) (p < 0.001) peroxidase activity. These changes were significantly improved treatment dose-dependent manner (30 100 mg/kg, respectively). (100 mg/kg, p.o.) showed similar protective dexamethasone (1 mg/kg, p.o.). cellular including interstitial edema, hemorrhage, infiltration PMNs, etc., which reversed administration. Histopathological examinations normal morphological structures tissue control group. biochemical histopathological examination appended iNOS CAT gene expression. mRNA expression increased levels decreased animals exposed LPS, while both gene. In conclusion, clearly demonstrated that caused effect LPS-induced ALI. results suggest may be used protect toxic lungs.
