The following phase II enzyme activities were also well maintained after cryopreservation: Phenol sulfotransferase (92%), 1-naphthol UDP-glucuronosyl transferase (95%), soluble epoxide hydrolase (87%), and glutathione S-transferase (88%), determined with broad spectrum substrate 1-chloro-2,4-dinitrobenzene.

Glucuronidation of 1-naphthol, bilirubin but not of testosterone could be followed in the microsomal fraction.
Activities of epoxide metabolizing enzymes (microsomal and cytosolic epoxide hydrolases; glutathione S-transferase) were also characterized in skin.

Microsomal and cytosolic epoxide hydrolase, glutathione S-transferase and phenol sulphotranserase were low or even below detection limit in FAO.
These enzyme activities were significantly higher in HPCT and correspond to about 1-10% the activities measured in PC. 4. 1-Naphthol UPD-glucuronosyl transferase activity was about 20% in FAO and about 100% in HPCT compared to PC. 5.

These cells also glucuronidated 1-naphthol efficiently (6 nmol/min per mg) and, at a lower extent, bilirubin (12 pmol/min per mg). 5.

The activities towards 4-methylumbelliferone, 1-naphthol, morphine or a monoterpenoid alcohol, nopol, supported by two different isozymes were significantly increased only with the highest dose; meanwhile bilirubin glucuronidation was 2-fold enhanced, whatever the dose used.

It was observed that the activities of microsomal epoxide hydrolase (with benz (a) pyrene 4-5 oxide as substrate), uridine diphospho glucuronyl transferase (with 1-naphthol as substrate) and cytosolic glutathione-S-transferase (with chlorodinitrobenzene as substrate) were altered exclusively due to zinc deficiency.
