| EImin, AU | 0.131 ± 0.033 | 0.142 ± 0.008 |
| Omin, mOsm | 187.8 ± 5.6 | 186.3 ± 2.5 |
| EImax, AU | 0.517 ± 0.052 | 0.547 ± 0.002 ** |
| OEImax, mOsm | 359.4 ± 18.9 | 355.3 ± 2.5 |
| EIhyper, AU | 0.259 ± 0.027 | 0.274 ± 0.001 ** |
| Ohyper, mOsm | 484.6 ± 7.6 | 462.0 ± 2.0 ** |
| Area, AU | 124.9 ± 14.2 | 118.4 ± 0.25 |
| Na, mmol/kg dw | 269.9 ± 13.7 | 264.8 |
| K+, mmol/kg dw | 13.7 ± 2.9 | 12.6 |
Means ± SD values from affected cat on three occasions (0.5, 4, and 6 months after surgery) and from five control cats. Ion content was measured on one occasion. # osmotic tolerance (area), deformability as maximal elongation index (EImax), osmolarity at which EImax is reached (OEImax), hydration state as the half-maximal tolerated hyperosmotic osmolarity (Ohyper), the elongation index at Ohyper, minimal tolerated osmolarity (Omin), elongation index at Omin (EImin), and dry weight (dw) [36]. ** Difference from the control (p < 0.05).
