[The diagnosis of cholecystitis by ultrasonic densitometry]. / Diagnostika kholetsistitov metodom ul'trazvukovoi densitometrii.

Ultrasound densitometry was used to determine echo density of the wall and contents of the gallbladder in normal persons and in patients suffering from cholelithiasis and chronic calculus-free cholecystitis. In patients with cholelithiasis, the gallbladder was later removed, followed by histological examination of its wall. The ultrasound and histological data were studied and compared. The highly significant differences in the echo density of the wall and contents of the gallbladder were obtained in normal persons and patients afflicted with chronic cholecystitis.

[Characteristics of arterial blood pressure in children aged 10-14 years living in Novosìbirsk (data of a simultaneous epidemiological study)]. / Kharakteristika arterial'nogo daleniia u detei 10-14 letzhitelei Novosibirska (po materialam odnomomentnogo épidemiologicheskogo obsledovaniia).

The authors reported the results of a study of BP levels in children aged 10 to 14 in Novosibirsk using a standard WHO method. Regional normal limits of systolic and diastolic BP with relation to age and sex were presented. The mean levels of systolic and diastolic BP were growing with age, particularly at the age of 11-12. Sex differences in the levels of systolic and diastolic BP were undetectable. In the group of children with raised BP the body mass index was increased, and a rise of diastolic BP was attended by atherogenic shifts in the blood lipid spectrum. Comparative assessment of BP levels was given for Novosibirsk, Moscow and American schoolchildren.
