The relationship between cytosolic concentrations of Ca2+ (Caz) and Na' (Na:) were studied in preparations of rat submandibular and pancreatic acini loaded with the Ca2+-sensitive dye Fura-2 or the Na+-sensitive dye SBFI. Pancreatic acini showed no changes in Na: during either transient or persisten
Acetylcholine (ACh) caused repetitive transient CI-currents activated by intracellular Caz+ in single rat submandibular grand acinar cells. As the concentration of ACh increased the amplitude and the frequency of the transient CI-currents increased. These responses occurred also in the absence of ex
