Histochemistry of the post-resuscitation changes in the brain

In 20 dogs, acid mucopolysaccharides, gangliosides, lysosomal enzymes and iontransport enzymes were investigated. Material was taken 2, 24 and 72 h after 15 min of clinical death due to electrotrauma. Changes in the post-resuscitation period indicated deterioration of transmembrane ion--metabolite transport in the brain. These changes had phasic variations that reflect the complexity of post-resuscitation processes.
