Figure 2:

Force (median) of evoked by electrostimulation of contractions of the myocafrdial strips of right ventricle of nonpregnant and pregnant (5-20 day) rats in experiments with blockers of beta-adrenoceptors - propranolol (10-8 g/mL; panel A) and atenolol (10-8 g/mL or10-6 g/mL; panel B) in a series with histidine (10-4 g/mL)
and adrenaline (10-5 g/mL). 
Note: stage 1 - perfusion with Krebs solution (force of contraction is taken as 100%); stage 2- effects of
adrenaline ( force in % of stage 1); stage 4 - impacts blocker (force in %% to the previous stage, i.e, force at perfusing with Krebs solution); stage 5 - effects of adrenaline on the background of blocker (in % to force at stage 4); stage 6 - effects of adrenaline on the background blocker and histidine (in % to force at stage 4). * - differences with comparison stage is statistically signifi cant at Wilcoxon test (p <0.05); 3,4,5 - the difference with the appropriate stage is statistically signifi cant for Wilcoxon test (p <0.05).
