1 Effect of parathyroid hormone and calcitonin on acetylcholine release in rat sympathetic superior cervical ganglion. Acetylcholine calcitonin-related polypeptide alpha Rattus norvegicus
2 The effects of parathyroid hormone (PTH) and calcitonin on acetylcholine release by rat superior cervical ganglion (SCG) were evaluated in vitro. Acetylcholine calcitonin-related polypeptide alpha Rattus norvegicus
3 PTH increased, and calcitonin inhibited, in a dose-dependent way, K(+)-elicited [3H]acetylcholine release, with apparent effective doses 50 of about 10(-9) M. The effect of PTH was inhibited by co-incubation with the PTH receptor antagonist NLe [8-18]-PTH (3-34) amide. Acetylcholine calcitonin-related polypeptide alpha Rattus norvegicus
4 The results indicate that, in vitro, PTH increases, and calcitonin inhibits, acetylcholine release in rat SCG. Acetylcholine calcitonin-related polypeptide alpha Rattus norvegicus
