ABSTRACT
The kidneys are one of main homeostatic organs participating in regulation of concentration of osmotic active substances, ionic composition and acid-base balance, in maintenance of volume of fluid of internal medium of organism fulfilling excretory function. The analysis of urine is largely applied in laboratory practice for detecting different pathological conditions. The actual study was organized to develop simple, accessible and economic mode of evaluation of functional condition of kidneys in patients with somatic diseases, detection of their early dysfunction and timely implementation of adjustment. The study was carried out on sampling of 78 patients: 58 persons with inflammatory diseases of intestine (ulcerous colitis, Crohn's disease) and 20 healthy persons (volunteers). The proposed technique is based on detection of total pool of metabolites in day urine of patients. The spectrophotometer is applied to detect main groups of metabolites of urine within range of wavelength 210-300 nm. The excess amount of pathologic components, toxically effecting and affecting homeostasis of internal medium of organism, is detected under establishment of total optical density. Its value is ≥30 standard unit and also sum of optical density within range 210-230 and 270-290 nm, equal 10 and 7 standard units correspondingly testify presence of glomerular and tubular apparatus of kidneys.
