| Abstract: | - 1.1. Changes in glomerular nitration rate (GFR), urine and blood properties and plasma catecholamines of carp were investigated during and following hypoxia.
- 2.2. GFR and urine flow decreased with increased urinary concentrations of bio-components, except protein, in the course of hypoxia.
- 3.3. Decreases in blood pH, and increases in haematocrit value and plasma K+, Ca2+, Mg2+, inorganic phosphate (Pi), ammonia, lactic acid and catecholamines (CAs) were observed as hypoxia progressed.
- 4.4. Increased GFR and urine flow, and higher values for urinary components, except protein, compared with those of the control were found in the initial post-stress stage.
- 5.5. The possible significance of increased plasma CAs in relation to changes in renal function in hypoxic carp is discussed.
