Effect of forskolin, acetylcholine, and acetylcholine in the presence of forskolin on efflux of ¹²⁵I from T₈₄ cells

Treatment	Basal efflux rate	Peak efflux rate
None (n = 9)	0.115 (0.076)	0.092 (0.024)
Forskolin (n = 9)	0.057 (0.014)	0.231 (0.057)*
ACh (n = 7)	0.102 (0.018)	0.063 (0.011)
ACh in the presence of forskolin (n = 9)	0.069 (0.012)	0.166 (0.033)*

Acetylcholine (ACh 50 μM) was given five minutes after forskolin (10 μM) to the basolateral surface. All values are apparent efflux rate constants (r/min), as described in the methods.

Data are means (SEM) (n = 9).

*p<0.05 compared with time matched basal controls.
