[Blood lipids and the incidence of hyperlipidemia in pilots]. / Lipidy krovi i chastota giperlipidemii u letnogo sostava.

The content of cholesterol and triglycerides was measured in healthy pilots. Over 1500 subjects were examined and age-related norms of the parameter were established. They were compared with published data. Physiological variations of cholesterol and triglycerides were related to age, height and body weight. The authors developed a method for diagnosing hyperlipidemia based on the agreement or disagreement between experimentally measured and theoretically calculated values. The authors maintain that hyperlipidemia can be diagnosed if the difference between the real and expected values is over 10%. The authors calculated the incidence of hyperlipidemia in all subjects examined (over 2100) and found that it was high: even in pilots of the age group 20-29 years hyperlipidemia occurred in 30% of subjects.

[Rare cases of severe heart rhythm disturbances during the hypoxic function test]. / O redkikh sluchaiakh tiazhelykh narushenii ritma serdtsa pri gipoksicheskoi funktsional'noi probe.

Cases of severe rhythm disorders of cardiac activity--the syncope developing lasting up to 34 seconds, are described in practically healthy individuals undergoing the hypoxic functional test. It is concluded that the hypoxic functional tests require a specially trained physician who must not only stop the test, but also give the patient immediate aid.
