Invasive pulmonary aspergillosis (IPA) is a life-threatening disease in immunocompromised patients that requires aggressive therapy. Because of the widespread use of antibiotics, corticosteroids, antitumor drugs, and immunosuppressive drugs, the morbidity of IPA is currently increasing. The ink secretion of molluscan species was identified as one of the novel sources of bioactive compounds. So the present study designed to investigate the antifungal and antioxidant effects of Sepia officinalis ink extract against IPA in mice. Eighty neutropenic infected mice were randomly assigned into four main groups (20 mice/group). The 1st group was treated with saline, neutropenic infected, the 2nd group was treated with ink (200 mg/kg) and the 3rd group was treated with amphotericin B (150 mg/kg) and the 4th group was treated with ink plus amphotericin B (Ink 200 mg/kg and AMB 150 mg/kg). Treatment was started at 24 h after fungal inoculation and was administered for 3 consecutive days. The present study demonstrated good in vitro and in vivo antifungal activity of IE against Aspergillus fumigatus. Compared with IPA group; IE-treated, AMBtreated, and AMB + IE-treated animals had a 67.80%, 83.41%, and 72.68% reduction in the pulmonary fungal burden, respectively. Treatment with IE and/or AMB for one and three days significantly decreased MDA and increased GSH and SOD levels in the lung tissues as compared with the infected untreated group. In conclusion, the results of our in vivo and in vitro studies demonstrate that IE has therapeutic effect against invasive pulmonary aspergillosis via reducing oxidative stress. {u00AA} 2014 The Egyptian German Society for Zoology.
