APPENDIX M

 

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
