[Hygienic aspects of wash water reclamation systems]. / Gigienicheskie aspekty razrabotki sistem regeneratsii sanitarno-gigienicheskoi vody.

The quality of reclaimed wash water and the composition of used wash water can be best determined by pH, oxygen chemical index, electric conductivity and chlorides that show individual variations but are sex-independent. Wash water contained mostly staphylococci and small amounts of sarcines, diplococci and micrococci. The use of washing and disinfecting agents may significantly modify the microbial characteristics of wash water, reducing noticeably its microbial content and increasing the content of organic substances and chlorides due to chemicals they include and due to more effective removal of sebaceous secretion. It is indicated that chemical components of washing and disinfecting agents that produce organic contaminants should be given special attention when developing a wash water reclamation system.

[Toxicologic and hygienic studies of water regenerated from oxidant-containing released moisture]. / Toksikologo-gigienicheskie issledovaniia vody, regenerirovannoi iz vlagovydelenii, soderzhashchikh okisliteli.

Toxic-hygienic examinations of water reclaimed from peroxide-containing technical fluids have shown that the water needs further purification using sorbents that contain a reducing agent. In the absence of the latter the reclaimed water exerts adverse effects on certain hematological parameters.

[Hygienic evaluation of the water reclaimed from various moisture-containing wastes]. / Gigienicheskaia otsenka vody, regenerirovannoi iz razlichnykh vlagosoderzhashchikh otkhodov.

The paper reviews 5 experiments on 25 healthy male test subjects, aged 20-36. For drinking and cooking they used water reclaimed from various water-containing wastes (atmospheric condensate, urine, fluids used in engineering processes and biological wastes) by the oxidation-catalytic and sorption techniques. The resultant water was saturated with salts and decontaminated by ionic silver at a dose of 0.1 mg/l. The experimental data on the excretion of water and minerals allow the conclusion that reclaimed and conditioned water is physiologically adequate and that the human body reacts to its intake as it does to normal potable water.

[Effect of nerobol on the water-electrolyte balance and kidney function in man during 120-day hypokinesia]. / Vliianie nerobola na vodno-solevoi obmen i funktsiiu pochek cheloveka pri 120-sutochnoi gipokinezii

The influence of anabolic steroids on the fluid-electrolyte metabolism and renal function of man was studied during a prolonged bed rest experiment. Seven test subjects were kept under surveillance. Three test subjects were given nerobol and four subjects served as controls. The fluid-electrolyte metabolism and the osmoregulatory function of the kidneys were studied. Nerobol induced a decreased excretion of sodium, potassium, calcium, chlorides and osmotically active substances. Nerobol produced the most pronounced effect on the calcium and potassium metabolism. The effect of the drug used during the prolonged bed rest experiment depended on the time and dosage as well as on the state of fluid-eletrolyte metabolism and the renal function.
