[Determination of the turbidity temperature of solutions of the nonionogenic surface-active agent LF-57 after the action on urinary calculi in uric acid].

Non-ionogenic surfactant LF-57 contributes solving of urinary calculi from uric acid and is a component of the drug Pharmalit for curing kidney-stone disease. Turbidity temperature was determined of the solution LF-57-78, 1C, and in the presence of uric acid--80.2C.

[Level of microelements in urinary stones after the action of surface-active agents].

Effect of non-ionogenic surfactant LF-57 on concrements from uric acid was studied. It was shown that the litholytic effect of this chemical was also directed on microelements. Composition of concrements and LF-57 was determined.

[Effect of several microelements contained in drinking water on the development of atherosclerosis].

During his whole life man drinks water - about 2 litres in 24 hours for an adult in the countries with moderate climate. Usually, drinking water contains many microelements. Their type and concentration depend mainly on the geochemical characteristic of the earth layers.
