The response of frog sciatic nerve action potentials
to x-irradiation and metabolic (carbon monoxide) or
transport (ouabain) inhibition was determined in an
attempt to further identify the nature of radiation
insult to nervous tissue. Carbon monoxide, ouabain
(2 X 10-5 M), and nitrogen anoxia were shown to
produce a near linear decline in action potential
amplitude. The carbon monoxide and nitrogen inhibitions
of activity were reversible in air; the carbon monoxide
inhibition was light reversible. Ouabain inhibition
was partially reversible by soaking the nerve in
aerated Ringer's. Application of 120 kv x-rays (75 Kr
at 4.9 Kr/min) to nerves during the linear decline in
spike amplitude brought about a marked enhancement (146%)
of inhibition by 99% CO/l% 02, nitrogen (136%), and
ouabain (265%). All bhanges were shown to be
Here’s what’s next.
