The study was broadened when a relationship between attacks of acute intermittent porphyria and the menstrual cycle in human females was suspected.
Patients studied were hospitalized on a metabolic ward, where caloric intake and output as well as diet constitution were measured by standard methods. All patients had a positive Watson-Schwartz test, and 24-hour porphobilinogen excretion was measured by the dilution or column methods
