ABSTRACT
Parameters of bromine injury were studied in vitro with the use of full-thickness human skin (HS) specimens--discards from various surgical procedures. The morphology of in vitro-treated HS resembled that of in vivo-injured skin. The damage was pronounced in the epidermis (destruction of the stratum corneum, and extensive vacuolation of keratinocytes) and the dermis (collagen coagulation), depending on the bromine concentration, exposure time, and application method. A decreased viability of epidermal cells, assayed by dye exclusion, was observed as well. Permeation parameters of bromine via abdominal HS were determined by quantitating bromine concentration in the donor and receiving compartments. The amount of bromine that permeated HS was inversely related to the concentration gradient applied. This in vitro study suggests that prompt treatment and early medical intervention may be required for successful healing of both severe and mild cases of bromine injuries.
