[The immune status of children with differing intensities of caries]. / Immunnyi status u detei s razlichnoi intensivnost'iu kariesa.

The present paper reports on the results of the studies of the quantity, functional activity of immunocytes and interrelation between their parameters in healthy children (12-14) with healthy periodontium which were ascribed either to caries-resistant or caries-prone group. In all the subjects venous blood and mixed saliva were investigated. Immune state was described through its parameters interrelations. This yields better detection of differences in immune states of both groups.

[The effect of exogenous adrenaline and angiotensin II on the resistance vessels of the cat kidney]. / Vliianie ékzogennykh adrenalina i angiotenzina-II na rezistivnye sosudy pochki koshki

In experiments with perfusion of the renal vessels with isotonic saline solution, the ability of angiotensin-II to activate the smooth muscle cells of these vessels was shown: both by direct myotropic action and in an indirect way - by catecholamines. Obvious tachyphylaxis is characteristic only for the direct myotropic effect of angiotensin-II. The data obtained suggest that the direct effect of angiotensin-II is selective for certain intrarenal vessels, while indirect action is more universal.
