Description
| - The effects of carbachol (CCh) on the frequency (f) of the miniature endplate potentials were tested at temperatures between 5 and 30 degrees C. Higher CCh concentrations, 1 x 10(-5) and 5 x 10(-6) M, reduced the f to 60 and the temperature dependence was negligible. However, an inverse temperature dependence was found when low concentrations 3 x 10(-7) and 6 x 10(-7) M were applied. The depression of f was 40-50 in 5-10 degrees C but only 10-20 of the control in the 25 and 30 degrees C. During application of CCh, the new steady of f was reached at temperatures between 5 and 30 degrees C within 17-20 min (Q10 = 1.07). Much greater temperature dependence of recovery was observed during washing out CCh (Q10 = 1.6). The temperature-independence of the steady state effects of CCh, good agreement with Langmuir adsorption-desorption theory and non-steady kinetics indicate that physical rather than receptor-mediated events are responsible for the depression of f.
