Research output: Contribution to journalConference article


A variety of fixatives and stains were examined for the ability to differentially stain the extracellular matrix components of thermal damage to the skin in an attempt to provide methods for examining the extent of thermal effects. This information is important in comparing different lasers and laser parameters. Four zones of thermal damage were identified including char and three zones of less extensive damage. The lower bounds of the damage with steady state conditions for these zones were 64-66 °C, 80-85 °C, and > 100 °C. The best choices based on this study include the following: Fixative: Bouin's, overall stain: H & E, inner zone stain: Pinkus' acid orcein giemsa, middle zone stain: Movat's pentachrome, and outer zone stain: The modified elastic stain presented in the appendix of this paper.
