[The age-related characteristics of changes in osmotic and ionic homeostasis in spontaneously hypertensive rats].

The 3-month old SHR differ from the WKY rats in that the former have an increased osmolality, concentration of albumins, activity (but not the concentration) of sodium and a reduced activity of potassium. The shifts in the albumins concentration occur, mainly, on account of the amino acid phenylalanine. The gradient increase of the sodium and potassium concentration between the plasma and muscular tissue in followed by a slight hyperpolarisation of the muscle fibers, a drop in the lability and a increase in pO2. The above shifts of homeostatic parameters were not revealed in the SHR and WKY rats of 1.5 and 6.0 months of age.

[Methodological bases for designing multipurpose laboratories].

A well-grounded selection of the necessary minimum of measuring facilities is of paramount importance in projecting multipurpose laboratories. These facilities should ensure the required accuracy of analyses to be carried out, and measurements covering the whole dynamic range of the values variations. It was suggested to organise new multipurpose laboratories in accordance with technical and economical reasoning and with the calculated generalized index which shows a compliance of technical characteristics of the measuring equipment chosen with the methodical demands.
