ABSTRACT

The experiments were performed on 3 sheep which had bi-polar platinic electrodes subserously implanted to the uterus shank and horns during an operation. The registration of uterus myoelectrical activity was conducted by the use of Reega Duplex XVI electroencephalograph. The tests were carried out on sheep in uterus, sensitised and non-sensitised with Stilboestrol-Polfa (0.04 mg kg^-1 i.m.). After recording the output uterus activity, the sheep were administered serotonin in continuous infusion in the quantity of: 12-24 g kg^-1 min^-1. The obtained results revealed that serotonin in sheep in anestrus, non-sensitised with stilboestrol, does not cause (within the scope of action potentials) any changes in the electrouterographic record. In sheep sensitised with stilboestrol, serotonin increases the uterus myoelectrical activity.

Key words: sheep, uterus, myoelectrical activity, serotonin.
