[Immunopathological circumstances in the structure of complications appearing after smallpox vaccination].

Investigations were carried out concerning the dynamics of antivaccinal antibodies and the structure of serum proteins in relation to the clinical manifestations following upon smallpox vaccination. In general, immunity is not apparently influenced by postvaccinal complications may be associated with immunoprotein perturbations, manifested by an increase in the alpha2-globulin fraction and, inconstantly, in the gamma-globulin fraction. Immunoelectrophoretic determinations revealed a relatively constant IgM and IgG deficiency.

[Clinical and biological aspects of chronic brucellosis].

The present study refers to 53 cases of chronic brucellosis admitted to the clinic or followed up in an out-patient unit for ten years (1962-1971). There was a total of 946 days in hospital and 1688 days of occupational disability, about 40% of the patients necessitating repeated hospitalization because of the relapsing course of the disease. This group of cases presented the classical dominant features of an occupational anthropozoonoses (90.
