SOME quite recent information as to the strengths of some of
the “trypsin injections” at present in use—in tuberculosis, and possibly also
in cancer—in Germany will be found in Archly fur klinische Chirurgie, vol.
xcv., part i., 1911. Here Dr. W. Bätzner puts on record his tests of five
trypsin injections by the Jochmann method. The figures give their comparative
potencies in dilution:
1. Fairchild,
made up February, 1906 .. .. 1 : 4,000.
2. Fairchild, made up October, 1909 .. .. .. 1 : 4,000.
3. Freund und Redlich, sixty days old .. 1 : 32.
4. Kahlbaum, freshly made up from powder
one and
a half years old .. ,. .. .. .. 1 : 32.
5. Merck, specially prepared
January, 1909 .. ..
1 : 64.
The
author (p. 5) remarks that the Fairchild preparation was by far the
best. While insisting that Nos. 3, 4, and 5 were very much too weak to be of
service in any treatment whatever—even of corns—the writer must also point out
that this particular (keeping) preparation Fairchild is not nearly strong
enough for use in cancer cases.
The writer once
again would refer to Chapter VII. of this book, in which the requirements of
really efficacious preparations of trypsin and amylopsin are set forth. If such
cannot be furnished for use in all civilized countries, it is for manufacturing
chemists to say this, and not offer
