Figure 1From: Histamine release and fibrinogen adsorption mediate acute inflammatory responses to biomaterial implants in humansPhagocyte accumulation on the surfaces of PET disks implanted in human volunteers, precoated with either plasma or serum derived from each volunteer. (A) Myeloperoxidase and non-specific esterase activities were measured on disks explanted after 24 h to reflect the degree of accumulation of PMN and MØ, respectively. (B) The estimated numbers of adherent PMN, MØ, and total phagocytes (PMN+ MØ) were calculated. Vertical lines denote ± 1 Standard Deviation. Significance vs. plasma-coated disks: * p < 0.05.Back to article page
