【 摘 要 】

Epithelial cells isolated by hyaluronidase incubation from rabbit small intestine were used to explore the presence of ionic channels by the patch-clamp method. Recordings were made from cell-attached or excised patches of basolateral membrane. Evidence was obtained for the presence of at least two kinds of channels conducting potassium currents. One of these can be shown to be activated by Ca²⁺.
