Fig. 1. Evolution of total creatine kinase activity (CK^tot;A ), total lactate dehydrogenase activity (LDH^tot;B ), and cardiac troponin I concentration (cTnI;C ) in the effluent of the preparations after the blow (cardiac injury) and in the control group. Numbers in brackets give the size of the groups. Newman–Keuls test:*P < 0.05 for between-groups comparison.
