[Water decontamination in the swimming pools: standardization and practice].

Practical examples were used to analyze possible ways and regimens of water decontamination with chlorine and ozone in the swimming pools when oxidants substantially interacted with the mineral and albuminoid ammonias that were present in the water. Ozone water decontamination was shown to be more effective than water chlorination and to rule out the generation of chloramines that were responsible for their strong irritating activity. Redox potential measurement used as an auxiliary method substantially alleviates on-line technological monitoring of the efficiency of water decontamination at the critical control point during chlorination and, during ozonation, makes up the existing gap of the current SanPiN 2.

[Adrenergic innervation of the middle and internal ear in man].

Adrenergic nervous structures (ANS) in morphofunctional formations of human middle and internal ear were studied on the autopsy material obtained from 5 victims of accidents free of any ear disease. The samples were treated histochemically with glyoxylic acid. Non-varicose dilated sympathetic nerve fibers (single and in bundles, non-myelinized, intensively luminescent, twisted and direct) were detected in vertical nerve sections, in spiral and vestibular ganglia, in chorda tympani.
