Of the dry antiseptics iodoform is constantly used in septic or tuberculous wounds, and it appears to have an inhibitory action on Bacillus tuberculosis.
excitatory synapses have positive reversal potentials whilst inhibitory ones have negative reversal potential.
The more important of those in use to-day are carbolic acid, the perchloride and biniodide of mercury, iodoform, formalin, salicylic acid, &c. Carbolic acid is germicidal in strong solution, inhibitory in weaker ones.
It is much more powerful than carbolic acid in its inhibitory action upon unorganized ferments such as pepsin or ptyalin.
But moderate doses of atropine markedly paralyse the terminals of the nerves that go to involuntary muscles, whether the action of those nerves be motor or inhibitory.
