Ginger efficiently reduced the lung damage and protected the lungs from severe damage due to hyperoxia and inflammation. - GreenMedInfo Summary

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% O 2 ) + lipopolysaccharide (LPS) group, the hyperoxia + LPS + ginger-treated group, and the control/no treatment group (21% O 2 ). 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-1β), 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-1β, 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.
