Inhibition effect of vagus and enhancement effect of hypoxia to cardiac sympathetic activity were verified with amperometric method. Both of these two effects were time limited.

A method for the determination of reduced form of nicotinamide adenine dinucleotide (NADH) using capillary zone electrophoresis with amperometric detection is DE - scribed.

With novel bulk micro-machining technique and novel surface modification method, a novel amperometric microelectrode sensor is presented.
