[Effect of low temperature treatment of liquid nutrient media on the reproduction of microorganisms].

The development of bacterial cultures of 37 microbial strains was studied after their 4-5 and 24 hour cultivation in liquid thawed and normal nutrient media. The cultivation of gram-positive aerobic bacteria, facultative anaerobic bacteria, actinomycetes and moulds in pre-frozen nutrient media increased 2-4 fold their reproduction as compared to that in the media that were not prefrozen. An insigificant acceleration of growth was found in six strains of gram-negative aerobic bacteria.

[Effect of inhalation of freshly melted water on the mucous membrane of the upper respiratory tract].

The authors conducted experiments on healthy people-volonteers and found that inhalation of freshly melted water definitely intensified the activity of the ciliated epithelium of the upper respiratory tract mucous membrane. They pesent result of the investigation permitting to eliminate the effect of ciliated epithelium "fatigue': after prolonged use of such inhalation. Data of comparative observations with the use of functional methods of investigation show that freshly melted water has a definitely normalizing effect on reflex stimulation, secretory function, temperature and other factors of mucous membrane activity.
