Fig. 3. — Radioimmunoassay results of 15 paired scar specimens expressed in micrograms of procollagen type III amino propeptide per milligram tissue wet weight after thawing. The insoluble material after exhaustive extraction is compared to the soluble fraction. 1,4 DAB results are also shown as box-and-whisker graphs and show significance (p < 0.05) compared with control-treated scars with respect to soluble procollagen type III amino propeptide only, by Mann-Whitney U test. The Kolmogorov-Smirnov normality test was shown to be valid. PIIIP, procollagen type III amino propeptide; RIA, radioimmunoassay; 1,4 DAB, 1,4-diaminobutane.
