Table 2. Histological scores of severity for kidneys 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
Glomeruli	0	0	1	1.67
Tubular structure	0	0.33	1.33	2.67
Epithelial cells	0.33	0.33	1.67	2.67
Fibrin deposition	0.33	0.67	1	1
Vascular dilation	0.67	0	1	1.33
Inflammatory cells	0.33	0	1	1.33
Fibrosis	0	0	0	0.33

Medulla	0	0	0	1
Global Histological Score	2.67 ±0.33	1.67 ±0.88	8 ±0.58 ( ** )	14 ±1.73 ( *** , §§ )

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<0.01);

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

§§ (p<0.01): significant versus 12 Gy Hind limbs-protected + Enrofloxacin).
