Illustrative microscopic presentation of the lung (a) (control), (b) (BPC 157)), liver (c) (control), (d) (BPC 157)), and stomach (e) (control), (f) (BPC 157)) (HE staining. (a–d) Presentation at the 20 min ligation-time, 5 min after saline (a,c) or BPC 157 (b,d) intragastric application. (a) Control rats with congestion and intralveolar hemorrhage; (b) no congestion and lung hemorrhage in BPC 157 rats; (c) liver parenchyma showed congestion in control; (d) BPC 157 rats showed no changes in liver parenchyma; (e,f) presentation at the 24 h ligation-time, saline or BPC 157 at 1 min ligation-time; (e) controls with erosive gastritis; (f) BPC 157 rats with no pathological changes. Magnification ×100 ((a,b) scale bar 100 µm), ×100 ((c,d) scale bar 50 µm), ×200 ((e) scale bar 100 µm), ×200 ((f) scale bar 50 µm).
