THE EFFECT OF CARBON MONOXIDE AND OF HYDROGEN SULPHIDE ON NERVE IRRITABILITY

FRANCIS O. SCHMITT 1 and LYLE V. BECK 1

1 THE DEPARTMENT OF ZOÖLOGY, WASHINGTON UNIVERSITY, ST. LOUIS, Mo.

1. Both carbon monoxide and hydrogen sulphide, which presumably inhibit cellular oxidations by combining with the iron-containing respiratory enzyme, render nerve non-irritable. The effects of carbon monoxide appear to be completely reversible, those of hydrogen sulphide, less so.

2. Illumination of nerves failing in mixtures of carbon monoxide and oxygen causes a temporary partial return of irritability and there is some evidence that there is an after effect of the illumination which may last some minutes.
