[Methodological approaches to the morphological assessment of the skin under slight toxic effects].

One-fold treatment of rat skin with 3% water solution of potassium bichromate resulted in slight toxic effects in epidermocytes, sebaceous gland cells and epithelial follicles. System of indexes for the slight toxic effects to assess was worked up.

[Hygienic evaluation of mineralizing lime substances for correction of mineral composition of low-mineral drinking water].

4 out of 6 mineralizing lime materials that were studied have been recommended for the practical application with the aim to correct the mineral composition of drinking low-mineralized water. The possibility to predict the biological properties of multicomponent mineralizing materials has been established on the basis of results of analysis of their chemical composition.
