ABSTRACT
As many as 54 patients with systemic lupus erythematosis presenting with the kidney damage and thirteen damage-free patients were studied for the dynamic surface tension (ST) of the urine with the aid of the computerized tensiometer MPT2. The condition is characterized by a drop in ST with the surface time equal to 1 second and a slope in the curve of tensiograms. The above findings have been secured in 53.7 and 71.6 percent respectively. In lupiform glomerulonephritis there is noted further lowering of the parameters. The proposed technique will, we believe, help in carrying out the differential diagnosis of the condition, assessment of the clinical course and degree of activity of the pathological process as well as in exercising control over efficiency of the therapeutic measures adopted.
