The object of the present study was to investigate the effect(s) of UV-B irradiation on the functional integrity, metabolic and detoxifying capacity of the isolated goat hepatocytes. Isolated goat hepatocytes were subjected to UV-B irradiation invitro for 0, 250, 500, 1250, 2500 and 7500 Joules/m2 which correspond to the irradiation time of 0, 1, 2, 5, 10 and 30 min. Cells were then analysed for Viability (Trypan blue exclusion test [TBE], 3-[4,5-dimethylthiozol-2yl]-2,5-diphenyltetrazolium bromide [MTT] assay, Membrane integrity (Lactate dehydrogenase [LDH] leakage, Lipid peroxidation) Detoxification (Ureagenesis, Cytochrome P450 activity [CYP450, Diazepam metabolism] and Glutathione-S-Transferase [GST] activity.

Ultraviolet-B (UV-B) irradiation in the range of 280-320nm has shown to be a promising immunomodulatory tool in xenogenic hepatocyte transplantation. Most of the studies documenting the effect(s) of UV-B irradiation on hepatic transplantation have been carried out in small model systems with very little information available in larger animals. The aim of the present investigation was to study in vitro the effect(s) of UV-B irradiation (302 nm) at 0, 250, 500, 1250 and 2500 J/m2 on the viability and cellular responses in the isolated goat hepatocytes.
