Ionic mechanisms in secretagogue-induced morphological changes in rat parotid gland

Abstract

When 10(-5) M carbachol was added to parotid tissue slices incubated in buffer containing Ca++, watery vacuoles were formed in the cells. The percent volume density of vacuoles, as measured from 0.5-micron sections, increased from 0.64 +/- 0.15 SE (n = 7) to 3.09 +/- 0.99 (n = 5) in 10 min and, finally, to 7.27 +/- 1.88 (n = 4) in 30 min. In electron… (More)
