ABSTRACT
The effects of direct influence of gravity on a cell have been studied. Potassium transport from infusoria. Tetrahymena pyriformis GL induced by the high gravitational levels which immobilize the cell (80, 140, 260 g) was examined. A minimum acceleration level at which the cells become motionless is 80 g. Kinetics of potassium output can be described as containing "fast" and "slow" component. The rate of potassium output relating to fast component does not depend on an acceleration level but is a function of the age and density of culture. The potassium output rate associated with slow component increases as acceleration is increased. It also rises in the course of time which points to a change of internal structure of the cells occurring the more rapidly the higher level of acceleration is. Direct effect of gravity on the cell is realized by two ways: 1) effect which results from difference of densities of cell and its environment; 2) effect on intracellular structures due to difference of their densities. It is supposed that the observed effects in main are being developed at the cost of a 2nd type of gravity effect.

Results of clinico-laboratory examinations of the endogenic intoxication in patients with injuries of the chest and abdomen are presented. Correlative relationships of the endogenic intoxication parameters and their association with the degree and character of injuries were established, the clinical informative value and prognostic significance of certain laboratory tests were determined. A conclusion is made on the necessity of a correction of endogenic intoxication in complex treatment of these patients.

Blood toxicity was estimated with the use of Tetrahymena pyriformis strain GL in patients with diffuse peritonitis. The time of the infusoria survival in the blood serum was a criterion of toxemia level. Infusoria life span was found to depend on peritonitis severity and serum concentration of medium-molecular peptides.
