ELECTROMYOGRAPHIC STUDIES ON THE OCCURENCE OF PERISTALSIS IN DOG'S URETER:(Ⅱ The Effect of Pinching or Cutting of the Ureter on the Ureteromyograms of Dog's. Ureter)

　第1報に引続き，機械的に尿管挾把及び切断を行なつた場合の尿管筋電図に就て述べる。

In squence to the previous study, the ure-ters of 32 adult dogs were pinched or cut at the pyelo-ureteral junction, the mid-part of the ureter or the uretero-vesical junction, under laparotomy and their electrouretero-grams were recorded under such conditions. The results obtained are as follows :

1. A normo-peristaltic discharge, a normo-peristaltic downward discharge, a simulta-neous, anti-peristaltic upward discharge, and an anti-peristaltic discharge were set off in the cases with the ureter pinched at the pyelo-ureteral junction, the mid-part of the ureter and the uretero-vesical junction, res-pectively.
