FIGURE 4.

Endogenous, rα1-ACT activity is attenuated in exudates obtained from nonhealing versus healing human wounds. A, box plot diagram illustrates activity of α1-ACT protein in exudates obtained from healing (n = 5) and nonhealing (n = 15) human wounds. B, box plot diagram illustrating segregation of exudates obtained from patients with nonhealing wounds in two subgroups, based on endogenous α1-ACT activity levels <1 (n = 10) or >1 (n = 5) mg/ml; asterisk and circle illustrate divergent values.
