The presence of ingested cottonseed protein in woman's milk

Abstract

1. 1. By means of the passive transfer technique the presence of cotton-seed antigen was definitely demonstrated in the breast milk of seven mothers of the twenty-four studied. In five the results were doubtful, in twelve they were negative. 2. 2. Milk specimens taken in six cases during the first two hours after the ingestion of the cottonseed meal contained little or no antigen. 3. 3. Milk specimens obtained in eighteen cases from two and one-half to twenty-four hours after the test meal gave definitely positive results in seven (39 per cent) and doubtful results in four cases (22 per cent). 4. 4. Donnally's findings that egg white ingested by the nursing mother can be demonstrated in her milk by means of the passive transfer technique have been duplicated with cottonseed.
