Mean histological score (range)
at entry	3.2 (2–4)	2.9 (2–4)	P>0.2
at 3 months	2.6 (1–3)	2.6 (2–4)	P>0.2
ESR (range)

at 3 months	10.6 (1–30)	10.86 (1–26)	P>0.2
CRP (range)

at 3 months	0.1 (0–0.3)	0.2 (0.1–0.6)	P = 0.072
WBC (range)
at entry	5850 (3200–9700)	5863 (3100–11600)	P>0.2
at 3 months	5517 (3100–9000)	6213 (3700–9200)	P>0.2

Symptom grades were scored according to Lichtiger et al.'s symptom score. Endoscopic and histological findings were scored according to Matts's grading score. ESR: erythrocyte sedimentation rate (mm). CRP: C-reactive protein (mg/dl). WBC: white blood cell (count/µl).
