The Inhibitory Effect of Haloxylon salicornicum on Contraction of the Mouse Uterus

Figure 4

Effect of synephrine on spontaneous contractions of the mouse uterus. (a) Concentration response curve examining the effect of synephrine on spontaneous contractions of 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 synephrine. The curve has been fitted to the Hill Equation and the HS1 data from Figure 3 is included for comparison. The effect of synephrine on the amplitude (b) and frequency (c) of the spontaneous contractions is also shown. The data is presented as mean ± s.e.m and 𝑛=4. ** indicates 𝑃<0.01 synephrine treatment versus control.
