Fig. 3From: Hypothermic treatment reduces matrix metalloproteinase-9 expression and damage in the liver following asphyxial cardiac arrest in ratsH&E staining of the liver sections from the normothermia (NT; A-E) groups and the hypothermia (HT; a-e) groups at sham, 6 h, 12 h, 1 day, and 2 days after asphyxial cardiac arrest (ACA). In the CA operated liver tissues, histopathology is markedly increased at 12-h post-CA. The histopathological changes are more increased at 1- and 2-day post-CA, showing the sinusoidal dilatation, vacuolization (asterisk), and infiltration of inflammatory cells (arrow heads). In hypothermic groups (HT; a-e), histopathological alteration was reduced as compared with the normothermia (NT; A-E) groups. CV, central vein. Scale bar = 50 μmBack to article page
