Isoprotenerol and octopamine diminish ovary muscle tone.
(a) Isoprotenerol strongly reduces basal muscle tone and inhibits maximal muscle contraction. (b) Octopamine strongly reduces basal muscle tone but enhances maximal muscle contraction. In both cases Chi-squared test and Dunnet´s multiple comparison test compared to control was P ≤ 0.0001, n = 6.
