[Electromyographic studies on the effect of transection-anastomosis of goat abomasum (author's transl)].
The four bipolar electrods were chronically sutured on the serosa of pylorus of four female goasts (29-36 kg in weight): from oral, electrod No. 1, No. 2, No. 3, No. 4. Electromyograms of abomasum were recorded before and after transection-end-to-end anastomosis of pylorus (between No. 2 and No. 3 electrods). The results are summarized as follows: 1. Before transection - anastomosis, anti-peristaltic discharge was not found in the pylorus. 2. After the anastomosis, prolonged discharge interval of peristalses and anti-peristaltic discharges occured in the upper part of the anastomosis (No. 1 and 2). 3. In the lower part of the anastomosis (No. 3 and 4), prolonged discharge interval of peristalses occured in all four goats, but anti-peristalic discharges were found in three goats. 4. Propagation velocity of anti-peristalic discharges became more faster than that of normo-peristalses.
