Intracellular photorelease of Ca 2+ from caged Ca 2+ (DM-nitrophen or nitr5) and the patch-clamp technique in the whole-cell configuration were used to investigate Ca2+-activated currents in inner hair cells (IHCs) of the mammalian cochlea.

The effects of the nematocyst venom of the sea anemone Bunodosoma cangicum on depolarization-activated currents were studied in opener crayfish muscle fibers and in cultured bovine chromaffin cells. The venom selectively and reversibly blocked the Ca2+dependent K+ current (IKcca)) present in crayfis

## Abstract The effects of rottlerin, a known inhibitor of protein kinase C‐δ activation, on ion currents were investigated in pituitary tumor (GH~3~) cells. Rottlerin (0.3–100 µM) increased the amplitude of Ca^2+^‐activated K^+^ current (I~K(Ca)~) in a concentration‐dependent manner with an EC~50~

To explore the involvement of a class of seven‐trans‐membrane‐span (7TMS) receptors in cellular signalling, a synthetic analogue (mas7) of the amphipathic tetradecapeptide mastoparan was used to mimic hormonal stimulus in guard cells of __Vicia faba__. The ability for mas7 to substitute for an activ
