Results and discussion

Any other information on results incl. tables

RENAL DAMAGE:
- Exposed and control female rats did not display any renal damage. 
- Male exposed rats exhibited increased cytoplasmic hyaline droplets in  proximal convoluted tubular epothelial cells, which were  indicative for  toxic injury. Additionally, foci of cellular degeneration were present  within proximal convoluted tubules. Intratubular 

cellular casts, overt  glomerular changes or significant inflammation was not seen.
METABOLITES identified (mean percentages in all 36 samples):
  1,2,3,4-tetrahydro-1-naphthol, CAS No. 529-33-9 (29 %)
  1,2,3,4-tetrahydro-2-naphthol, CAS No. 530-91-6 (7 %)
  1,2,3,4-tetrahydro-1-oxo-2-naphthol (33 %)
  1,2,3,4-tetrahydro-1-oxo-4-naphthol (25 %)
