[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.

[Reproducibility of spectrophotometric and flame photometric methods].

The reproducibility of the studied biochemical methods was determined by means of the criterion of dispersion of the results approaching the average arithmetic value--the coefficient of variance 'V'. A total of thirty analyses per series were made of one and the same sample, under one and the same conditions, by one and the same laboratory assistant. The blood plasma of cows was studied spectro-photometrically with regard to the levels of urea, total protein, sialic acids inorganic phosphorus, carotene, cholesterin, alkaline phosphatase, aldolase, GOT, GPT, and whole blood (for blood sugar).
