Inter-laboratory surveys have shown that "routine methods" of urinary protein determination are often unsatisfactory. Therefore, we compared six frequently used methods for determination of protein in urine with respect to linearity, within-batch and between-batch precision, comparative bias, and practicability. We assayed dilutions of human and bovine albumin and serum, and fresh and lyophiliz...

Variation of the protein content in urine of patients known to excrete protein in excessiveamountswas studied. Variation in different specimensobtained from the same patient on a particular day and from day to day were studied. A total of 293 urine specimensexcreted over a 3to 6-day period by 25 patients were examined. No particular pattern of protein excretion was observed. The morning specime...

In the crystal structure of the title compound, C(9)H(7)N(2)O(2)S(+)·C(7)H(5)O(6)S(-)·2H(2)O, an H atom from the 5-sulfosalicylic acid is transferred to the pyridyl N atom, forming a salt. The dihedral angle between the thiazole and pyridinium rings is 5.909 (5)°. The crystal packing is determined by O-H⋯O and N-H⋯O hydrogen bonds involving water mol-ecules.

the abscission of alstroemeria petals is the serious problem at the industry of cut flowers of this plant. in this study, cut alstroemeria cv. bridal flowers were pulsed with solutions containing natural essential oil carvacrol, gibberellic acid and benzyladenine (50 and 100 mg l-1), -5-sulfosalicylic acid (1 and 1.5 mm) and sucrose (5 and 10%) for 24 hours. the distilled water was used as cont...

The results of studying the physical properties a deep eutectic solvent based on choline chloride and sulfosalicylic acid have been presented. A phase diagram for this two-component mixture has constructed, dependences its density refractive index temperature studied first time. molar refractivity under study calculated. possibility using as an extractant recovery metal ions in solid–liquid sys...

The kinetics of leaching zinc from hemimorphite was investigated. factors that influence were also evaluated, and a kinetic model built. In addition, scanning electron microscopy-energy dispersive spectroscopy (SEM-EDS) used to investigate the changes surface morphology before after leaching. By decreasing particle size increasing temperature, 5-sulfosalicylic acid concentration, stirring speed...

A unidimensional Thin Layer Chromatography system for the separation of salicylic acid and its derivatives (sulfosalicylic acid and Aspirin) has been developed. The separation was successfully using a solvent system of chloroform-methanol-water-ammonium hydroxide 120:75:6:2 (V/V) as mobile phase on TLC plates impregnated with boric acid. The method is based on different behavior of investigated...

Cocrystallization of 1-hydroxy-ethyl-2-methyl-5-nitroimidazole (metronidazole) and 5-sulfosalicylic acid (5-H(2)SSA) from methanol solution yields the title salt, C(6)H(10)N(3)O(3) (+)·C(7)H(5)O(6)S(-). In the crystal structure, the ions are linked by a combination of inter-molecular O-H⋯O, N-H⋯O and C-H⋯O hydrogen bonds, forming a three-dimensional framework. The hydroxyl group of the cation i...

URING THE PAST HALF CENTURY a large number of tests for the detection of protein in the urine have been described. Three of these tests have gained outstanding popularity and are widely used in clinical practice. These are the sulfosalicylic acid test, the nitric acid ring test, and the heat and acetic acid test. Because of the wide usage of these tests as a part of “routine urinalysis” there i...
