[Hygienic evaluation of the methods of water conditioning on marine ships]. / Gigienicheskaia otsenka sposobov konditsionirovaniia vody na morskikh sudakh.

Results of test stands and of field studies (on marine ships) have shown, that the use of installations for water preparation (IWP), including mineralizers of the wash out type and ozonizers, makes it possible to get water of stable quality independent of the terms of operations of the installations, and also provides the possibility of conditioning of shore water supply and of carrying out disinfection of the ship water supply system. Comparative analysis of the operation of various kinds of IWP on marine ships testifies to the necessity of development of the new types of IWP, which will promote health preservation of crew members having difficult long independent voyages.

[Use od ozone for disinfection of ships' system of water supply contaminated by Pseudomonas aeruginosa]. / Primenenie ozona dlia dezinfektsii sudovykh sistem vodosnabzheniia infitsirovannykh sinegnoinoi palochkoi.

Experimental substantiation is given of the use of ozone in doses, recommended for disinfection of water and ship water supply systems infected by Pseudomonas aeruginosa. The positive effect of ozonation of water supply systems infected by Pseudomonas aeruginosa was confirmed by results of field testing on ships of the Black sea marine steam-navigation.

[Pathogenetic significance of the immediate and delayed types of hypersensitivity reactions in the dynamics of nephritis]. / Patogeneticheskoe znachenie reaktsii giperchuvstvitel'nosti nemedlennogo i zamedlennogo tipov i dinamike nefrita.

Complex study of the immunologic status of rats from the first days after the injection of nephrotoxic serum up to formation of chronic renal failure in comparison with functional and morphological characteristics of the disease confirmed the hypothesis on the phasic development and different pathogenetic role of the hypersensitivity reactions of the immediate and delayed types during nephritis. Signs of the immediate hypersensitivity predominated during the initial stages of the disease; realization of this hypersensitivity is indicated both by the liberation of the mediators of the pathochemical phase and by the change of the renal processes. The development of delayed hypersensitivity reactions plays the basic role in the pathogenesis of chronic nephritis.
