摘要

PROBLEM TO BE SOLVED: To obtain a gel which forms a secure gal exhibiting adhesiveness in vital tissues, is excellent in the hemostasis of a wound surface, eliminates the danger of a virus infection, is harmless and has no problems in safety by mixing specific compds. with gelatin. SOLUTION: This gel is obtd. by mixing the gelatin soln. and the soln. of at least one kind of the compds. selected from compds. of formula I (R2 , R3 , R5 , R6 are H, alkyl; Z1 , Z2 are the nonmetal atom groups necessary for forming a pyrolopyridine ring; R1 , R4 are groups having acid bases; L is methine; X- is anion; (m) is 3, 4; (n) is 1, 2, n=1 when an intra-molecular salt is formed) and/or formula II (R7 , R8 are H, alkyl; R9 is an H molecule, halogen, univalent org. group; K is halogen, OH, alkyl group, etc.; (p) is 0 to 4; R10 is a group substd with an acid).
