Table 2. Immunostaining scores for tumor necrosis factor-alpha (TNF-α), interleukin-1 beta (IL-1β), and inducible nitric oxide synthase (iNOS).

Groups	Scores
	TNF-α	IL-1	iNOS
Saline	0 (0–0)	0 (0–1)	0 (0–1)
Scratch	0 (0–1)	1 (1–2)	2 (0–3)
5-FU+ Saline	2 (1–3)*	2 (1–3)*	3 (2–3)*
AMF 50 mg/kg + 5-FU	0 (0–1)#	0 (0–2)#	1 (0–3)#

Data are reported as median and range of six samples. *P<0.05 vs saline group. ^#P<0.05 vs 5-FU group. Data were analyzed by Kruskal-Wallis and Dunn's tests. 5-FU: 5-fluorouracil; AMF: amifostine.
