Figure 5From: A novel fungus concentration-dependent rat model for acute invasive fungal rhinosinusitis: an experimental study A. fumigatus hyphae invasion in sinus cavity mucosa of rat with acute invasive fungal rhinosinusitis (AIFR). Bone resorption is caused by the intrusion of hyphal masses. The hyphae are antler-like. (A1. Hematoxylin and eosin staining, ×20; A2. Hematoxylin and eosin staining, ×40; B1. Periodic acid–Schiff staining, ×10; B2. Periodic acid–Schiff staining, ×40; C. Methenamine silver staining, ×40; D. MUC5B staining, ×40).Back to article page
