[Feeding behavior of people in advanced age].

In the article the questions of eating attitudes of people in advanced age are considered. Inspection of 54 people of St. Petersburg in the age from 65 to 84 included questioning (biological, social and questions of eating contents), estimation of eating attitude (the eating attitude test EAT-26, the Dutch eating behaviour questionnaire) and psychological testing (techniques of an estimation of complaints, attitudes, levels of anxiousness, depression, astenia, aggression and quality of life). Symptoms of eating disorders with restrictive and emotional tendencies were registered in 14,8% of people of advanced age. Communications of eating attitude with social factors, eating preferences, application of a diet, a degree of a dissatisfaction of body weight, arterial blood pressure and psychological parameters have been revealed.

[People and their symbiotic microflora: general biological aspects of the problem].

[The light diffusion technique for estimation of the size of urine particles in patients with type 2 diabetes mellitus in the Tamm-Horsfall protein precipitation].

Tamm-Horsfall uroprotein accounts for more than 50% of the urinary proteins in healthy individuals. In abnormalities, it creates a favorable background for detecting smaller-sized uroproteins and for diagnosing pathological processes from the results of native urine tests. In this connection, there is a need for precipitating Tamm-Horsfall glycoprotein while applying laser correlation spectroscopy to analyze the size of urine particles in patients with type 2 diabetes mellitus. Eighty patients with this condition concurrent with different stages of diabetic nephropathy and 23 apparently healthy individuals were examined. The findings suggest that the subfraction urine composition before and after Tamm-Horsfall protein precipitation is different in apparently healthy individuals and patients with type 2 diabetes mellitus concurrent with diabetic nephropathy. This is most likely to be due to the change in the qualitative composition of protein as renal lesion progresses, to the specific features of protein excretion at different stages of a pathological process, and to different concentrations of other low and high molecular-weight proteins.
