[Changes in the immunologic status of myocardial infarct patients at various times in its course].

Cell-mediated and humoral immunity parameters were investigated at different dates of myocardial infarction and compared with the blood tests. A diagram is proposed correlating changes of immune status to blood test results, as an instrument for the assessment of changes in immune status on the basis of blood composition. Immunologic changes (defense immunodeficiency and developing cytotoxic component) associated with acute myocardial infarction, and disorders of immunologic control persisting to the time of discharge were demonstrated.

[Experimental development of immunity to pertussis].

Experiments on animals inoculated intracerebrally with B. pertussis culture No 18-323, serovar 1.2.

[Vaccine from the cell fragments of Bordetella pertussis. I. Protective, sensitizing properties and morphological characteristics of the vaccine].

The authors present the results of studying the protective and sensitizing properties of a new preparation made of a ultrasonic disintegrate of pertussis microbes treated by ethyl ether. As shown by electron microscopy, the preparation consisted of the cell wall elements (the membrane), remnants of the cytoplasm and protectosome, i.e.
