[Content of blood lipids and characteristics of dyslipoproteinemias in people exposed to radiation during the accident at the Chernobyl nuclear power station]. / Soderzhanie lipidov krovi i kharakteristika dislipoproteinemii u lits, podvergshikhsia radiatsionnomu vozdeistviiu pri avarii na Chernobyl'skoi AES.

Lipid and lipoprotein spectrum of the blood plasma was investigated and phenotyping of hyperlipoproteinaemias was carried out in men exposed to ionizing radiation and suffered from acute radiation illness as a result of the Chernobyl accident. An increase of the total cholesterol triglycerides and content frequency of atherogenic types of hyperlipoproteinaemias in comparison with average levels of population both a year and 3 years after irradiation was observed. No essential differences were found between the obtained indices 1 and 3 years after irradiation which testified to the stability of the revealed disturbances.

[Characteristics of functional tests with isometric loads used in the diagnosis of ischemic heart disease]. / Kharakteristika funktsional'nykh prob s izometricheskimi nagruzkami, ispol'zuemykh v diagnostike ishemicheskoi bolezni serdtsa.

Cardiovascular response to isometric stress (IS) applied to the upper and the lower extremities, and general isometric stress amounting to 30% of the maximum productive force (MPF) were compared in 50 normal subjects and 60 coronary patients. Hemodynamic values were significantly higher at 30% MPF general isometric stress tolerance threshold, as compared to those seen in the last minute of the maintenance of IS of the same force by the upper extremities. Hemodynamic responses to IS, applied to the lower extremities, and to general 30% MPF isometric stress were basically similar. The general 30% MPF isometric stress was more sensitive with respect to the diagnosis of coronary disease, while the test's specificity and predictive value were fairly high. The sensitivity of the lower-extremity IS test was somewhat lower, as compared to that of the general isometric stress test, yet it is much higher, as compared to the upper-extremity IS test, and can therefore be used in screening programs.
