[The effect of Ca++ on gastrin output and LESP before and after antrectomy (author's transl)]

Previous investigations show that calcium infusion stimulates gastrin output in healthy volunteers, whereas after antrectomy calcium does not cause any significant change of IRG levels. Both healthy volunteers and antrectomized patients (B II) show a continuous increase of LESP, reaching a maximum after 120 minutes. These results suggest a direct interaction of Ca++-ions and gastrointestinal smooth muscle cells.
