Effects of Ethanol on Contraction Strength of Chick Neck Striatum Muscle Following Electrical Stimulation of the Nerve

Introduction: Ethanol is a suitable solvent for many in vivo and ex studies. However, it can interfere with normal muscle contraction make variations the results. Contrary to present study, previous investigations revealed suppressant effect of ethanol on contraction. Methods: This study was based an isolated chick biventer cervicis nerve-muscle using twitch tension recording technique. Nerve complexes were exposed several concentrations (100, 200, 300, 400, 500 mM), impulses recorded. Results: Twitch height increased time dose-dependent manner, concentration mM after 30 minutes most elevation impulses. Conclusion: The potential effects striated are important should be considered studies as solvent.
