[The effect of influenza and para-influenza on the course of ischemic heart disease].

A retrospective analysis was made of 541 case reports of patients with coronary heart disease admitted to the infectious department with the diagnosis of influenza (n-387) and parainfluenza (n-154). In all the patients, the diagnosis was verified serologically with the aid of the hemagglutination inhibition test, with a 4-fold and greater increase of the antibody titer in the serum. In part of the patients, it was confirmed by the above test combined with immunofluorescence in examining rhinopharyngeal smears and in part of influenza patients, it was verified virologically.

[The incidence of exacerbations in chronic diseases in patients hospitalized with influenza and para-influenza].

A retrospective analysis was made of the case reports of 829 patients admitted to the infectious department with a diagnosis of influenza (592) and parainfluenza (237). In all the patients, the diagnosis was supported serologically with the aid of the hemagglutination inhibition test, with the antibody titer in the serum rising 4-fold and more. In part of the patients the indicated test was used in combination with the immunofluorescence test in studying nasopharyngeal smears, whereas in part of the patients, it was coupled with virological tests.

[A comparison of the dynamics of changes in large intestinal mucosa of acute dysentery patients with detection of a specific antigen in urine].

The relationship between the elimination of shigellae from the body with urine and the dynamics of morphological changes in the mucous membrane of the large intestine of acute dysentery patients at the early convalescence period has been studied. The persistence of Shigella antigen in acute dysentery patients and its elimination with urine is, as a rule, accompanied by local immune cell reaction in the mucous membrane of the large intestine. The antigen circulating in the body is a factor contributing to the inflammatory process in the intestine, the amount of the eliminated antigen being higher in pronounced inflammations of the intestinal mucosa than in residual inflammatory phenomena.
