In an experiment with 7-d immersion of 8 male test-subjects (21-26 y.o.) we investigated excretion with urine of total protein, creatinine, urea, uric acid, glucose, K, Na, Ca, P, Mg, 12 groups of proteins and 5 enzymes. Results of the investigation bring to the conclusion that 7-d immersion does not impact the kidney functioning. Analysis of uroproteinogram failed to detect shifts in glomerular filtration or tubular reabsorption which correlates with the absence of significant changes in uroenzymogram. Even profuse diuresis was unable to provoke abnormally high protein and glucose excretion, whereas electrolyte excretion normalized fairly soon. Increased excretion of creatinine, urea, Ca, Mg and P appears to reflect activation of catabolism in skeletal muscles.

UI MeSH Term Description Entries
D007101 Immersion The placing of a body or a part thereof into a liquid. Submersion,Immersions,Submersions
D007668 Kidney Body organ that filters blood for the secretion of URINE and that regulates ion concentrations. Kidneys
D007684 Kidney Tubules Long convoluted tubules in the nephrons. They collect filtrate from blood passing through the KIDNEY GLOMERULUS and process this filtrate into URINE. Each renal tubule consists of a BOWMAN CAPSULE; PROXIMAL KIDNEY TUBULE; LOOP OF HENLE; DISTAL KIDNEY TUBULE; and KIDNEY COLLECTING DUCT leading to the central cavity of the kidney (KIDNEY PELVIS) that connects to the URETER. Kidney Tubule,Tubule, Kidney,Tubules, Kidney
D008297 Male Males
D011507 Proteinuria The presence of proteins in the urine, an indicator of KIDNEY DISEASES. Proteinurias
D012016 Reference Values The range or frequency distribution of a measurement in a population (of organisms, organs or things) that has not been selected for the presence of disease or abnormality. Normal Range,Normal Values,Reference Ranges,Normal Ranges,Normal Value,Range, Normal,Range, Reference,Ranges, Normal,Ranges, Reference,Reference Range,Reference Value,Value, Normal,Value, Reference,Values, Normal,Values, Reference
D003401 Creatine An amino acid that occurs in vertebrate tissues and in urine. In muscle tissue, creatine generally occurs as phosphocreatine. Creatine is excreted as CREATININE in the urine.
D005500 Follow-Up Studies Studies in which individuals or populations are followed to assess the outcome of exposures, procedures, or effects of a characteristic, e.g., occurrence of disease.

D005919 Glomerular Filtration Rate The volume of water filtered out of plasma through glomerular capillary walls into Bowman's capsules per unit of time. It is considered to be equivalent to INULIN clearance. Filtration Rate, Glomerular,Filtration Rates, Glomerular,Glomerular Filtration Rates,Rate, Glomerular Filtration,Rates, Glomerular Filtration
D006029 Glycosuria The appearance of an abnormally large amount of GLUCOSE in the urine, such as more than 500 mg/day in adults. It can be due to HYPERGLYCEMIA or genetic defects in renal reabsorption (RENAL GLYCOSURIA).
