Abstract
The effect of Ca ions on electrical responses of gastric gland cells to histamine and prostaglandins E2 and F2 alpha was studied using intracellular glass microelectrodes. The hyperpolarization evoked by histamine and prostaglandin F2 alpha was decreased in hypocalcium solutions and did not occur in Ca-free solution. The Ca ions seem to be necessary for the hyperpolarization responses of gastric gland cells to histamine and prostaglandins.
摘要
使用细胞内玻璃微电极研究了钙离子对胃腺细胞对组胺、前列腺素E2和F2α的电反应的影响。在低钙溶液中，组胺和前列腺素F2α引起的超极化减弱，而在无钙溶液中则不发生。钙离子似乎是胃腺细胞对组胺和前列腺素产生超极化反应所必需的。
