Tail length and tail intensity in kidney cells of control (C) Swiss albino mice and mice subjected to two-hour anaesthesia with halothane (H), sevoflurane (S), or isoflurane (I) at 0, 2, 6, and 24 h after anaesthesia (based on the total score of 200 comets per group (40 comets per animal)

Tail length and tail intensity in kidney cells of Swiss albino mice exposed to halothane (H), sevoflurane (S), or isoflurane (I) and/or gamma-irradiation (60Co) of 1 Gy 0, 2, 6, and 24 h after irradiation [(based on the total score of 200 comets per group (40 comets per animal)]

Tail length and tail intensity in kidney cells of Swiss albino mice exposed to halothane (H), sevoflurane (S), or isoflurane (I) and/or gamma-irradiation (60Co) of 2 Gy 0, 2, 6, and 24 h after irradiation [(based on the total score of 200 comets per group (40 comets per animal)]

Statistical differences (Mann–Whitney U test; p<0_05), in tail length (TL, μm) and tail intensity (TI, % of DNA in comet tail) in kidney cells of Swiss albino mice treated with halothane, sevoflurane, or isoflurane alone or in combination with 1 or 2 Gy gamma-irradiation (60Co) compared to corresponding controls at the same time point
