Background/aim: Hyperoxia- and inflammation-induced lung injury is an important cause of the development of bronchopulmonary dysplasia (BPD) in premature infants. We aimed to ascertain the beneficial effects of ginger (Zingiber officinale) on rat pups exposed to hyperoxia and inflammation. Materials and methods: Thirty-six newborn Wistar rats were randomly divided into 3 groups as the hyperoxia (95% O2) + lipopolysaccharide (LPS) group, the hyperoxia + LPS + ginger-treated group, and the control/no treatment group (21% O2). Pups in the hyperoxia + LPS + ginger group were administered oral ginger at a dose of 1000 mg/kg daily during the study period. Histopathologic, immunochemical (SMA and lamellar body), and biochemical evaluations including total antioxidant status (TAS), total oxidant status (TOS), malondialdehyde (MDA), myeloperoxidase (MPO), tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1ß), interleukin-6 (IL-6), and caspase-3 activities were performed. Results: Better weight gain and survival rates were shown in the hyperoxia + LPS + ginger group (P < 0.05). In the histopathologic and immunochemical evaluation, severity of lung damage was significantly reduced in the hyperoxia + LPS + ginger group, as well as decreased apoptosis (ELISA for caspase-3) (P < 0.05). Tissue TAS levels were significantly protected, and TOS, MDA, and MPO levels were significantly lower in the hyperoxia + LPS + ginger group (P < 0.05). Tissue TNF-α, IL-1ß, and IL-6 concentrations were significantly decreased in the ginger-treated group (P < 0.05). Conclusion: Ginger efficiently reduced the lung damage and protected the lungs from severe damage due to hyperoxia and inflammation. Therefore, ginger may be an alternative option for the treatment of BPD.
