1918 Excerpt: ...as such has a nutritive effect is very old, and it
even seems that by means of hyperemia the deficient stimulus to
formation of bony tissue in absent formation of callous can be
fanned into life." From this we see how all important hyperemia is,
both in causing the elimination of the infection, and in promoting
the activity of the regenerative forces, and I am sure that to one
who partially appreciates the defensive and life giving forces of
the blood, a preparation, that, when introduced within the soft
tissues surrounding the teeth, is capable of producing a marked and
lasting hyperemia of the parts. This preparation, which is known as
the ethyl borate gas, is especially prepared, at the time of its
administration, in a machine particularly adapted to its making.
Necessary Aids The gas is an unstable oxygen compound, formed by
the uniting of the Dunlop compound oxygen with the Dunlop ethyl
borate solution. In the free state it is a transparent,
semi-volatile liquid of a slightly acrid taste, but pleasant odor.
In the gas machine, and under pressure of about one-half an
atmosphere, or seven pounds, the liquid becomes surcharged with
oxygen from the specially prepared gas in the tank, and is
discharged through the needle as a highly diffusible oxyethl-borate
gas with the oxygen in loose combination. Upon its release into the
soft tissues of the mouth, the oxygen is separated from the
compound and passes into the blood, while the ethyl borate is
precipitated into the interstices of the soft tissues. Though still
active, the oxygen thus liberated is so modified as to have lost
considerable of its oxidizing powers, and is taken up by the blood
without producing any untoward symptoms. The oxygen joins with the
hemaglobin, producing oxy-hemaglobin ud libera...
