摘要: Abstract Some properties of the trout bladder-contracting substance (UHS), extractable with hot acetic acid from teleost urophyses, were investigated pharmacological and chemical means. Observations UHS activity on isolated bladder indicated that was not due to following: acetylcholine, 5-hydroxytryptamine, histamine, adrenaline noradrenaline, or neurohypophysial peptides (arginine vasopressin, arginine vasotocin, isotocin, oxytocin). The blocked by atropine. In addition, gave responses different acetylcholine small intestine goby did produce any visible effects rat blood pressure uterus when applied in doses about 10 times higher than those necessary induce rhythmic contractions bladder. destroyed incubation trypsin chymotrypsin; it also partially treating alkali.
