Fig. 7. Effects of WIN 55,212-2 and 2-AG ether on the Na+ currents. (A)
Reversible inhibition of the Na+ current by 10 µmol
l1 WIN 55,212-2. The currents were elicited by a 20 ms pulse
from a holding potential of 84 mV to a test potential of 24 mV.
The current traces labelled ac were obtained at the times indicated by
the same letter on the time course. (B) Representative example of time course
of the current signal. (C) Na+ current magnitudes before and after
superfusion with each drug. Values are means ±
S.E.M. Numerals within parentheses are number
of the cells sampled.
