The Inhibitory Effect of Haloxylon salicornicum on Contraction of the Mouse Uterus
Figure 6
Effect of propranolol on the inhibitory action of HS1 and HS2. (a) Representative recording showing spontaneous contractions of the mouse uterus and how they are unaffected by the nonselective β-antagonist propranolol (20 μM). In the presence of propranolol the inhibitory action of HS1 (3 μg/mL) was largely prevented. All recordings are from the same mouse uterus. (b) Summary data showing how propranolol affects the inhibitory action of HS1, synephrine, and HS2 (all at 3 μg/mL) on the mouse uterus. The data represents the integral of the contraction-time record and is expressed as a percentage of the control response in the absence of propranolol. The data is presented as mean ± s.e.m and . ** indicates that for HS2 versus propranolol alone.
