ABSTRACT
The absorbed doses of radiation for dominant species of natural ecosystems of Polesski State radio-ecological reserve were calculated. The received values, absence of morphological anomalies in plants, and stability of their specific and numerical structure indicate high resistance of phytocenosis to the influence of radiation.

A study is presented of the central hemodynamics, renal function and water-salt metabolism in 42 patients with ischemic heart disease and chronic circulatory insufficiency (grades I and II) and revealed a deterioration of these indices in this categories of patients manifested in a retention of sodium, deterioration of central hemodynamics after increase of venous inflow.

Contact thermography was performed in 87 patients with benign and in 75 with cancerous tumours of the breast. Hyperthermia over the tumour is characterized by a 2.2 degrees C and higher increase of the temperature and was registered only in cancer of the breast. Anisothermy of the breast was characterized by a +/- 0.5 degrees C and higher and may be considered as a supplementary diagnostic sign distinguishing cancer of the breast from benign tumours.

The present paper studies lipoprotein of human blood plasma in the norm and pathology. The three informational groups of lipoprotein crystals are isolated, which correspond to certain types of diseases. The question of possible diagnostics of some diseases by means of the lipoprotein crystals type in the polarized light is under discussion.
