1. Elevation of [K(+)](e) induced a contraction of rabbit aorta. If 10 mM-La(3+) was applied to rabbit aortae prior to [K(+)](e) elevation no contraction occurred. When 10 mM-La(3+) was applied simultaneously with, or at short time periods after, elevation of [K(+)](e) graded contractions were obtained whose magnitudes were higher if La(3+) was added at a later stage.2. Net cellular Ca fluxes associated with these graded contractions were measured using (45)Ca as well as atomic absorption… CONTINUE READING
