Table 1. Histological scores of severity for livers collected 64 days after irradiation from 12 Gy-irradiated rats with hind limbs or head protection treated with Enrofloxacin and control rats treated or not with Enrofloxacin.

Parameters	C	C + E	12 Gy HL-p + E	12 Gy H-p + E
Hepatocytes	1,67	2	2.67	2.33
Hepatocyte rows	0	0	0.67	1.67
Steatosis	0	0	0	0
Sinusoids	0.67	0.67	0.33	1.33
Fibrosis	0	0	0	0.67
Macrophages	0.67	0	1	1
Lymphocytes	1	1	1	1
Necrosis	0	0	1	1.33
Global Histological Score	4 ±0.58	3.67 ±0.33	6.67 ±0.33 ( * )	9.33 ±0.88 ( *** , § )

Rat Groups: C: Control; C + E: Control + Enrofloxacin; 12 Gy HL-p + E: 12 Gy Hind limbs-protected + Enrofloxacin; 12 Gy H-p + E: 12 Gy Head-protected + Enrofloxacin. For each parameter and for each rat group, values represent the average of scores obtained in three animals. Global histological scores represent average values (± SEM) of cumulated histological scores obtained from three rats for each group

* (p<0.05);

*** (p<0.001): significant versus control + Enrofloxacin;

§ (p<0.05): significant versus 12 Gy hind limbs-protected + Enrofloxacin).
