The relationship between NE level and myocardial damage. A: Starting from the initiation of intravenous infusion of saline or NE, goat blood samples were collected during (T0-T60) and after infusion (A-T30-180) at designated time points. Serum samples were subjected to measurement of NE level and each group was plotted in a curve (Con = saline, NE group was named according to the infused NE concentration. This group name is applicable for subfigure B and C). B: Representative micrographs of myocardial tissue of goats at 3 hours after the completion of NE for groups, Con, NE1, NE5 and NE10; at 30 min after NE infusion for group NE30 (×24000). C: Quantitative results of mitochondrial damage as observed in B.
