Pettenkofer and Vogt determined that diabetics absorbed less oxygen than healthy persons, and that hence we might hope, by introducing more into their system, to obviate some conditions of their malady.
Bouchardat, and also Demarquay, have recorded cases relieved by this treatment, but no extensive trial of it has been made. Peroxide of hydrogen has been given internally with the same object - of oxygenation- and with some partial success.
I have tried oxygen-inhalation in several cases of diabetes in which prostration, dyspnoea, and tendency to cyanosis were prominent symptoms -one case was at the very unusual age of seventeen months, another at thirteen years, and three others at adult age. The gas certainly relieved for a time the symptoms mentioned, although it did not in any instance reduce the sugar in the urine.
