In vitro effects of propranolol on the TE-induced acute heart dysfunction. Propranolol at 1 μmol/L was pre-administrated followed by a dose of 180 μg TE in Langendorff-perfused rat hearts. Parameters including HR (a), LVDP (b), LVEDP (c), dp/dtmax (d) and -dp/dtmin (e) were recorded. Data are expressed as mean ± SD (n = 8), * P < 0.05 vs. the control, # P < 0.05 vs. TE
