Hematoporphyrins 0-15 complement C3 Homo sapiens 84-87 15125391-10 2004 The mean plasma concentrations of C3a des Arg were 1246 +/- 832 ng/ml for HP, 1148 +/- 774 ng/ml for CD and 639 +/- 217 ng/ml for AN69 and significant difference was found comparing HP vs AN69, CD vs AN69 (p < 0.05). Hematoporphyrins 74-76 complement C3 Homo sapiens 34-37 15125391-21 2004 Modified cellulose membranes HP and CD induce higher C3a concentrations and superior leukopenia rate compared with AN69. Hematoporphyrins 29-31 complement C3 Homo sapiens 53-56
