Ficus carica Puree Exerts a Higher Antioxidative Profile in Hypoxic Lungs after Intermittently Inducing Hypoxia in Sprague–Dawley Rats

Abstract

Background The body produces more hypoxia-inducible factor and reactive oxygen species in response to hypoxic situations because they cause unbalanced oxygen levels. Ficus carica provides numerous benefits because of its high antioxidant and mineral content. Nevertheless, the mechanism by which F. carica consumption confers this protective benefit remains incompletely understood. Aim This study aimed to evaluate how F. carica puree (FCP) can affect the antioxidant enzyme activity and malondialdehyde (MDA) levels in the lung by mitigating the effects of intermittent hypoxia (IH). Methods Thirty Sprague–Dawley rats were divided into five groups: negative control (NC), untreated; positive control (PC), treated with aquadest; FCP1; FCP2; and FCP3, which received FCP at doses of 1.25, 2.5, and 5 mL/200 g body weight. The treatment was administered for 4 weeks before inducing IH (10% O2 and 90% N2) into all groups (except NC) for 4 h for 7 days. Furthermore, hemoglobin (Hb) level, lung MDA level, and lung superoxide dismutase (SOD) enzyme activity were assessed. Results The Hb level did not exhibit a significant increase under IH conditions. Conversely, the PC group exhibited the least activity of lung antioxidant enzymes and the highest lung MDA levels. In addition, the FCP intervention group exhibited lower MDA levels than the PC group and ameliorated relative lung weight loss. Conclusion All FCP intervention groups showed lower MDA levels and higher SOD levels compared to the PC group, suggesting that FCP could mitigate the effects of hypoxia in rat lungs.
