[Detection of Signs of Thrombus Formation in Patients With Typical Atrial flutter].

Aim: to assess rate of detection of markers of thrombi formation and to determine whether transthoracic echocardiography data or clinical characteristics predict severe left atrial appendage [LAA] dysfunction (low LAA velocity, severe spontaneous echo contrast [SEC], LAA thrombus) in patients with typical atrial flutter (AFI).

Material And Methods: Consecutive 406 patients (299 with atrial fibrillation [AFib] and 107 with AFI) underwent transesophageal echocardiography before cardioversion. Mean age was 59.

[Determination of Shigella antigens in the feces of people, immunized with enteral vaccine prepared from S. flexneri antigen].

The dynamic determination of the presence of the specific antigen and its activity in the excreta of humans subjected to enteral immunization with vaccine prepared from S. flexneri antigen was made in the agglutination test and neutralization test with the use of, respectively, antibody and antigenic erythrocyte diagnosticums. In the feces and urine of the vaccinees antibodies occurred less commonly and, as a rule, they were less active than those detected in dysentery patients at the corresponding time from the beginning of the disease.

[The possibility of using the demonstration of Shigella antigens in the study of the epidemic process in dysentery].

The detection of Shigella antigens in feces in accordance with the results of the passive hemagglutination test is more effective than the bacteriological method for finding out persons infected with Shigella, especially in the absence of pronounced clinical manifestations of dysentery, and can be used in the study of the mechanism of the epidemic process. The examination of two groups, each consisting of permanent and temporary members, has revealed that the use of this method for detection of the antigen makes it possible to perform the epidemiological analysis of morbidity and, in particular, to determine the source(s) of infection.
