Inhibition of caffeine contractures of slow rat muscles by urea and its derivatives.

D O Karpenko, S A Krolenko.   

Abstract

Contractures induced by rapid cooling of rat soleus muscles in the presence of low concentrations of caffeine (2-3 mmol.l-1) have been studied. Urea, methylurea and 1,3-dimethylurea inhibit reversibly these contractures as well as caffeine contractures (20 mmol.l-1, 30 degrees C) but do not affect twitches. This finding leads support to the idea of the existence of different mechanisms activating contraction in response to caffeine action or deplorization.
