From: Angiotensin II type 2 receptor antagonist reduces bleomycin-induced pulmonary fibrosis in mice
Histologic sections of the left lung 14 days after the last dose of bleomycin (BLM). (a) BLM group. Pulmonary fibrosis with definite damage to the lung structure is visible. (b) BLM + olmesartan medoxomil 1 mg/kg group. Increased fibrosis with definite damage to the lung structure and formation of small fibrous masses were partially observed. (c) BLM + PD 5 mg/kg group. Increased fibrosis with definite damage to the lung structure and formation of small fibrous masses were partially observed. (d) Control group. The normal alveolar structure is visible.
