2. Fig. 1
Hematoxylin and eosin staining shows an open laser channel (C) 1 mm in diameter bordered by a 1- to 2-mm broad rim of necrotic, carbonized myocardium (lower third of Fig. 1). (×200 before 38% reduction.)

3. Fig. 2
Lie staining reveals an open laser channel (C) bordered by a 1- to 2-mm broad rim of necrotic myocardium (lower third of Fig. 1), followed by a 1- to 3-mm rim of myofibrillated degeneration (MFD) and edema with a beginning focal demarcation by granulocytes (middle third) and normal myocardium (N) (upper third). (×200 before 38% reduction.)
