[Skin response to phytohemagglutinin in patients with typhoid fever, bronchial asthma and Hodgkin's disease].

The skin response to phytohemagglutinin was investigated as an index of cellular immunity in group of 50 children made up of 11 with thypoid fever, 13 with bronchial asthma type I, 15 with Hodgkin's disease and 11 controls. A mild but statistically significant (p less than 0.005) depression was found in the skin response of patients with typhoid fever and moderate in patients with Hodgkin's disease. In patients with bronchial asthma, it was similar to control cases; thus, in the future, finer parameters are considered necessary in these cases to investigate cellular immunity.
