[Silent Myocardial Ischemia as a Result of Cardiac Autonomic Neuropathy].

Aim: to verify the effect of vegetative nervous system on the silent myocardial ischemia.

Materials And Methods: We included in this study 56 patients with functional class II-III effort angina (22 men and 34 women, age 45-49 years) with silent myocardial ischemia (SMI). Examination included 24hour blood pressure and ECG monitoring.

Detection of mycobacterial lipoarabinomannan with an antigen-capture ELISA in unprocessed urine of Tanzanian patients with suspected tuberculosis.

A direct antigen-capture ELISA based on the detection of mycobacterial lipoarabinomannan (LAM) in unprocessed urine was evaluated for its usefulness in clinical practice. In Tanzania, 231 patients with suspected pulmonary tuberculosis (TB) and 103 healthy volunteers were screened with standard TB tests and with the new LAM-ELISA. Of 132 patients with confirmed pulmonary mycobacterial disease (positive sputum culture), 106 were positive using the LAM-ELISA (sensitivity 80.

[Development of a method of polarization fluorescence immunoanalysis of the herbicide 2,4,5-trichlorophenoxyacetic acid].

Immunoreagents were produced and a polarographic fluorescent immunoassay was developed for estimation of residual content of widely used herbicide 2,4,5-trichlorophenoxy acetic acid. The procedure is simple, accurate, specific and allowed one to measure 10 preparations within 7 min. The sample volume was 50 microliters and the minimal content of the substance estimated was 0.

[The immunological properties of the main outer membrane protein of Legionella].

The immunogenic properties of Legionella outer membrane main protein (OMMP) were studied by its effect on the proliferative activity of lymphocytes in guinea pigs. Preliminary immunization with OMMP activated only the specific and nonspecific proliferation of spleen cells. After infection with Legionella, secondary immune response developed in the spleen and lungs of previously immunized animals, in contrast to intact ones, and the nonspecific proliferative activity of lymphocytes in the spleen and lungs of previously immunized animals considerably increased.

[Isolation and primary characteristics of the common species-specific outer membrane protein of Rickettsia prowazekii].

Common species-specific protein is isolated for the first time in the chromatographically pure state from the outer membrane of Rickettsia prowazekii, and its amino acid composition is determined. As revealed by chromatofocusing technique, the protein possesses pI 4.18 +/- 0.
