Figure 2: Effect of epinephrine on rat trachea smooth muscle contractions induced using potassium chloride (60 mM) with and without 1 μm propranolol. The statistical differences in the data in the experimental groups were found using one-way analysis of variance and Tukey tests with SPSS-16 software; P<0.001was considered as significant for all concentrations
