Ex vivo gelation tests of collagen gels in artificial porcine stomach ulcers.

Notes: (A) Artificial ulcers (30 × 30 mm) were induced in excised stomach tissues and were elongated vertically by gravity. (B) A stomach specimen on an aluminum plate tilted at 60°. (C) Artificial ulcer with 0.5% collagen sol in 1 × NPB containing 4 mM genipin. (D) Artificial ulcer with 1.44% collagen sols in 1.6 × NPB containing 4 mM genipin. Artificial ulcers were elongated by gravity. Stomach specimens (C and D) were stored at 37°C for 2 h after application of collagen sol.

Abbreviation: NPB, neutral phosphate buffer.
