Abstract
Conclusions
1. By comparing the titre of diphtheria antitoxin of maternal blood and the globulin extracted from a placenta one may arrive at equivalents which are also equivalent in measles prophylaxis. This offers a method of measuring dosage of placental globulin extract. Ten experiments performed indicate that this, with the exception cited, is true. 2. The measles antibody and diphtheria antitoxin are both contained in the globulin fraction as extracted. 3. Globulin extract when properly applied as to dosage and conditions of exposure is effective in measles prophylaxis.
