>By our researches we have established in what consists the generic difference between inhalation anesthetics and narcotics.

In our experiments no increase in the H-ion concentration was produced by morphin or by scopolamin, no matter how deep the narcotization.

In animals already narcotized by morphin the production of acid by any of the acid-producing stimuli was delayed or prevented. On the other hand, in animals in which an acidity had already been produced by ether, by shock, by anger, or by fear, the later administration of morphin delayed or inhibited entirely the neutralization of the acidity.

In other words, morphin interferes with the normal mechanism by which acidity is neutralized possibly because its inhibiting action on the respiratory center is sufficient to overcome the stimulating action of acidity on that center, for, as we have stated, the neutralization of acidity is in large measure accomplished by the increased respiration induced by the acidity itself.

SUMMARY

Acidity inhibits the functions of the cerebral cortex, but stimulates those of the medulla. This antithetic reaction to the stimulus of increased H-ion concentration is an adaptation to prevent animals from committing suicide by overactivity, for the mechanism for the initiation and control of the transformation of energy is in the higher centers of the brain, while an essential part of the mechanism for the neutralization of acidity—the centers governing circulation and respiration—

is in the medulla. This explains many clinical phenomena—

why excessive acidity causes paralysis, why there is great thirst after inhalation anesthesia, after excessive muscular activity, excessive emotion—after all those activities which we have found to be acid-producing, for water, like air, neutralizes acids.

The excessive use of alcohol, anesthetics, excessive work, intense emotion, all produce lesions of the kidney and of the liver.

The explanation is found in the fact that all these stimuli increase the acidity of the blood. and that, if long continued, the neutralizing mechanism must be broken down and so the end-products of metabolism are insufficiently prepared for elimination.

 

In view of these considerations we may well conclude that the maintenance of the normal potential alkalinity of the blood is to be estimated as the keystone of the foundation of life itself.
