“…Since the first in vitro studies of ureteric function appeared about 1900, no systematic analysis of the influence of acid-base changes upon ureteric smooth muscle contractility has been made, although spontaneous contractions have been studied in various muscle bath solutions ranging from pH 5.6 to 8.4 (Boyarsky and Labay, 1972). Roth (1917) considered that Locke's solution with pH 8.1 to 8.3 was best suited for eliciting maximal spontaneous contractions and rhythmicity of animal ureters. Decreasing pH was associated with a lowering of tone and rhythmicity.…”

“…Our observations upon the effects of drugs do not accord with those of other authors working on other animals. Roth (1917) found adrenaline to raise the tone in isolated dogs' ureters, but noted no differences in response from different parts. Satani (1919 a) and Gruber (1930) found the isolated ureter of the pig to respond to adrenaline by an increased rate of contraction, but noted no effect on tone.…”

“…Atropine has no effect on spontaneous contractions at doses which abolish contractions induced by acetylcholine. Most animals species investigated, including cat (Lucas, 1908), dog (Roth, 1917;Malin et al, 1968), pig (Longrigg, 1974a & b;Muschat, 1929), rabbit (Gosling & Waas, 1971), rat (Finberg & Peart, 1970) and water-buffalo (Gould et al, 1955), have been shown to possess excitatory a-adrenoceptors as in human tissue. Less consistent responses have been found when using f3-adrenoceptorand muscarinic-agonists.…”
