[Value of various criteria of assessment of a test in stress echocardiography in diagnosis of ischemic heart disease].

Aim of investigation was to study significance of electrocardiographical and echocardiographical criteria of development of angina attack, and their combination in assessment of results of stress echocardiographical tests (stress-echo) with various stress-agents. Stress echocardiography, coronary angiography and left ventriculography were carried out in 928 patients (805 men and 123 women) aged 31 - 72 years with suspected ischemic heart disease (IHD).

[Evaluation of the efficacy of collection media used in hospital inspections].

A total of 2303 parallel studies of washings off hospital environmental objects were carried out with 1% sugar broth and 1% peptone water used as enrichment media. Sugar broth was found preferable for the isolation of Staphylococci and gram-negative nonfermenting bacteria. Direct inoculations of washings off the environmental objects collected at treatment and prophylactic institutions for Staphylococci were found ineffective.
