Abstract
This study tested whether duodenal application of lithium inhibits gastroduodenal motility, and whether it suppresses secretion from the exocrine pancreas. Five suckling pigs, 16–18 days old, were surgically fitted with 3 serosal electrodes on the wall of the gastric antrum and the duodenum for electromyography of smooth muscles, and with a pancreatic duct catheter and a duodenal T-cannula for collection and re-entrant flow of pancreatic juice. After the recovery period, on alternative days, each animal was tested once with an intraduodenal infusion of Li+ (100 mmol·L–1C3H5LiO3,10 mL·kg−1·h−1) for 1 h, and once with an intraduodenal infusion of NaCl (154 mM, 10 ml·kg−1·h−1), also for 1 h, with the first treatment, i.e., Li+ or NaCl, randomly assigned. Individual pigs served as their own controls, with data recorded prior to a treatment being used as the baseline. Li+ increased the duration of quiescence (P < 0.05) and activity phase (P < 0.05) in the antrum, thus increasing (P < 0.05) the duration of antral myoelectrical cycles. Li+ shortened (P < 0.05) phase I, but it did not affect phase II or phase III or the MMC in the duodenum. Li+ inhibited pancreatic juice outflow as well as pancreatic enzyme and bicarbonate output (P < 0.05 for all pancreatic parameters).
