Abstract

The effects of various Ca2+ antagonists and aminoglycoside antibiotics on the Ca2+ channel in isolated outer hair cells of the guinea pig were investigated using a whole-cell patch-clamp technique. The inhibitory action was in the order of La3+ ≫ Cd2+ ≫ Ni2+ ≫ Co2+ for inorganic Ca2+ antagonists, and flunarizine = nicardipine > ω-Conotoxin > methaxyverapamil = diltiazem ≫ amiloride for orgaini ones. Aminoglycoside antibiotics also had antagonistic effects on the Ca2+ channel.
