..., but its existence and function in non-mammalian non-vascular smooth muscle have not been examined. In the present study we examined H 2 S production and its physiological effects in urinary bladder from steelhead and rainbow trout ( Oncorhynchus mykiss ) and evaluated the relationship between H 2 S...

...STEVEN J. YOUMANS; CATHERINE R. BARRY SUMMARY An earlier report indicated that acid secretion in turtle urinary bladder is driven by an unusual vacuolar H + -ATPase and that the ATPase accounts for essentially all acid secreted. These results, however, are difficult to reconcile with the acid...

...B. James Curtis; Chris M. Wood ABSTRACT The relative roles of the kidney and urinary bladder in ion, fluid and acid-base regulation were examined in freshwater rainbow trout chronically infused with either 140 mmol I -1 NaCl or 140 mmol I -1 NaHCO 3 (3mlkg -1 h -1 ) for 32 h. NaCl had a negligible...

...B. James Curtis; Chris M. Wood ABSTRACT Two different approaches were employed to examine the possible urine storage and ionoregulatory functions of the urinary bladder in vivo in the freshwater trout. An indirect approach, using non-catheterized fish, involved ‘spot sampling’ from the bladder...
