Effect of cholinergic antagonist atropine on [Ca2+]i stimulated by BzATP or carbachol in lacrimal gland acini. Time-dependent increase in [Ca2+]i induced by stimulation of lacrimal gland acini with BzATP (10−4 M) or carbachol (Cch, 10−4 M) after a 30-minute preincubation with atropine (10−4 M). Traces from three to five experiments (A). Mean change in peak [Ca2+]i from three to five experiments (B). Values are mean ± SEM. Arrows: time of addition of agonists. *Significant difference between agonist alone and agonist plus antagonist.
