Abstract:
Quantitative histochemical demonstration of the nonspecific esterase in injuredskin on 32 Hartly guineapigs and 8 cases of human skin wounds was performed,using a microspectrophotometric scanning technique.In all antemortem incisions andlacerations,including those made at the agonal stage,the nonspecific esterase acti-edvity can be observed in the dermal collagen fibers in the vicinity of the woundedge.The enzyme activities increase with the antermortem duration of the injuries.Both total content and mean concentration of the nonspecific esterase in the woundedge between antemortem and postmortem wound groups are significantly different(P
