The ingress of blood into the SPG-178 gel. (a) The ability of SPG-178 and Viscoat hyaluronic acid to allow the inward diffusion of blood after immersion for 2 min in 2 ml of blood. (b) Area occupied by blood in SPG-178 (black diamond) and Viscoat (black square) (p = 0.002 (repeated ANOVA), *p = 0.01 (0 min); **p < 0.01 (2, 4, 6, 8, 10 min) by unpaired Student’s t test). The error bars represent the standard deviation of the means (SDs, n = 3). (c) The peptide forms an antiparallel beta sheet structure in an aqueous solution by electrostatic interaction and forms one fiber.
