We have studied variations in absolute numbers of lymphocytes under conditions of daily living in small groups of normal controls and psychoneurotic patients. There CIRCULATING LYMPHOCYTES DURING STRESS AND NON-STRESS INTERVIEWS (MEAN VALUES) [See Source Pdf for Fig. 8] seems to be little difference between the controls and patients with anxiety neuroses in either males or females. In the female patients, a considerable group had diagnoses of hysteria, and in these the level of lymphocyte numbers during the day seemed appreciably lower than in the other groups.In a series of 13 pairs of stress and non-stress interviews, in 8 of the 13 there was evidence that the discussion of disturbing topics produced a mild alarm reaction.Abstract Teaser
