Isoflurane provides long-term protection against focal cerebral ischemia in the rat.

abstract：BACKGROUND:Neuronal voltage-dependent potassium (K) currents are crucial for various cellular functions, such as the integration of temporal information in the central nervous system. Data for the effects of intravenous anesthetics on human neuronal K currents are limited. It was the authors' aim to evaluate the concen...
