[Effect of Bulgarian preparation, Nivalin, on bioelectrical activity of the ureter].

The authors examined the influence of the Bulgarian preparation Nivalin on the bioelectrical activity of practicaly healthy ureters of cats under the conditions of acute experiment. They used on the average 1,5--2 mg of Nivalin per kg of body weight as the whole amount was used singly and administered intravenously. They found that Nivalin caused the appearence of more frequent bioelectrical complexes of ureters, which in most cases was manifested in two phages--the first almost 1--15 minutes after the injection and the second-after 60--90 minutesmthere was also an improvement of the rhythm of the bioelectrical activity and amplitude changes in bioelectrical complexes.
