Effects of a benzodiazepine on the muscle membrane architecture of the rat diaphragm. A freeze-fracture study.
1. Midazolam increases, stimulation-independently, the amount of intermembraneous particles on the sarcolemma of the muscle fibres of the diaphragm. 2. Midazolam does not affect the amount of orthogonal arrays of particles on the sarcolemma. 3. Possible mechanisms for the action of midazolam are discussed.
