Microdialysis data.

<p>Panels a-d depict data from three eligible animals (one from group A with perfusate A and two from group B with anti-inflammatory perfusate B). Data are displayed as individual measurements per time interval. RD_urea (%) was expressed as median (min-max) of values obtained on day 4. Symbols denote: *p<0.05 and **p<0.01 <i>vs</i>. rat A. Statistical approach was restricted to the evaluation of inter-individual differences owing to low number of subjects. Possible effect of 5-ASA (perfusate B) could not be determined. Due to ethical reasons the attempts to harvest more data were discontinued.
