RESUMO
The first data illustrating work efficiency of health centres in this country are presented. They suggest the necessity to change both the strategy of activities and the patient population. Studies on variability of cardiac rhythms and characteristics of vegetative status in adolescents showed that the equipment used is poorly adapted to the purpose.

The chromatomass-spectrometry method was for the first time employed to study organic substances isolated by vapour-phase extraction from the Matseta sulfide-containing mineral water near Sochi. These substances are found to contain sulphur in different valent forms. A new technique has been developed for the detection of monobasic C2-C6 carboxylic acids in natural mineral water based on the combination of sequential vapour extraction and extractive freezing of the analytes. The proposed method is readily reproducible and has a detection limit of 0.03 mg/l for the analysis of carboxylic acids in water.
