D. Wisdom et al., EFFECT OF SECRETIN ON VAGAL STIMULATION-EVOKED EXOCRINE PANCREATIC-SECRETION IN THE RAT, Revista Espanola de Fisiologia, 49(1), 1993, pp. 31-35
The effect of secretin on nerve-mediated pancreatic juice secretion in
the anaesthetized rat has been studied. Vagotomy caused a significant
reduction in the rate of pancreatic juice flow, total protein output
and amylase secretion being compared to control values prior to vagoto
my. Both secretin (intravenous infusion 10(-10) mol/kg body weight/h)
and electrical stimulation of the vagus nerves (4 V, 2 ms, 20 Hz) caus
ed marked increases in flow, total protein output and amylase output.
Pretreatment of rats with atropine (0.1 mg/kg body weight) abolished t
he electrical stimulation-evoked secretion. However, simultaneous intr
avenous infusion of secretin and electrical stimulation did not yield
either a clear additive response or a potentiation of secretory respon
ses.
