Abstract:
:The adenosine triphosphate (ATP) content of keloids and scars resected from patients was demonstrated by high-performance liquid chromatography. The surface color of hypertrophic scars was red or pink and that of atrophic scars was white. The ATP content of red scars was (in mmol/g protein) 1.06 +/- 0.14, of pink scars 0.12 +/- 0.02, of white atrophic scars 0.19 +/- 0.06, and of keloids 1.06 +/- 0.19. The longer the elapsed time after the trauma, the lower the level of ATP in scar tissues (correlation coefficient = -0.506; p = 0.005 by Spearman's rank correlation). However, ATP levels in keloids were still high 10 years after the injury. Fibroblasts and fibrocytes in keloids and scars were counted in histologic preparations stained with hematoxylin and eosin. The average number of fibroblasts in a definite area (56 x 10(-4) mm at a magnification of x400) was 4.8 in keloids, 5.1 in red scars, 2.4 in pink scars, and 1.3 in white atrophic scars. The number of fibrocytes in the same area was 0.4 in keloids, 0.4 in red scars, 2.3 in pink scars, and 1.3 in white atrophic scars. These results indicate that keloids and red hypertrophic scars have higher ATP levels and contain more fibroblasts than pink or white scars, and they also suggest that the levels of ATP and the number of fibroblasts decrease when red hypertrophic scars change into atrophic scars. In keloids, ATP and fibroblasts seem to remain at high levels for a long time.
