B: Inclusion Criteria (main):

* Active ulcerative colitis except proctitis, i.e. inflammation minimal 15cm ab ano, confirmed by endoscopy and histology
* Established or new diagnosis
* Disease activity at baseline: Clinical Activity Index (CAI) \>4 and Endoscopic Index (EI) \>= 4

Exclusion Criteria (main):

* Crohn's disease
* Toxic megacolon
* Present or past colorectal cancer
* Symptomatic gastrointestinal disease
* Serious secondary disease(s)
* Baseline stool positive for germs causing bowel disease
* Immunosuppressants within 3 months and/or corticosteroids within 1 month prior to baseline

* Serum creatinine \>= 1.2x upper limit of normal (ULN) and creatinine clearance \< 60 ml/min per 1.73 m2
* Serum transaminase (ALT and/or AST), and/or alkaline phosphatase \>= 2x ULN
C: Inclusion Criteria:

(1) Male or non-pregnant, non-lactating females, 18 years of age or older. (2) Documented diagnosis of UC with disease extending at least 15 cm from the anal verge.

(3) Active UC defined by:

(a) modified UC-DAI score of 4-10 with (b) sigmoidoscopy component score ≥ 2 and (c) rectal bleeding component score ≥ 1 (4) Ability of subject to participate fully in all aspects of this clinical trial.

(5) Written informed consent must be obtained and documented.

Exclusion Criteria:

1. Severe UC defined by the following criteria:

   ³6 bloody stools daily with one or more of the following:
   1. oral temperature \> 37.8°C or \> 100.0°F
   2. pulse \> 90/min
   3. hemoglobin \< 10 g/dL
2. Previously failed treatment with a mesalazine dose of \> 2.0 g/day.
3. Current relapse lasting \> 6 weeks in the opinion of the investigator.
4. Treatment with 5-ASA at a dose of \>2.0g/day within 1 week prior to randomisation
5. Treatment with systemic or rectal steroids within 4 weeks prior to randomization.
6. Treatment with immunosuppressants within 6 weeks prior to randomization.
7. Treatment with infliximab or other biologics within 3 months prior to randomization.
8. Treatment with systemic antibiotics for UC within 7 days prior to randomization.

17. Immediate or significant risk of toxic megacolon.
18. Hypersensitivity to salicylates, aspirin, sulfasalazine or 5-ASA.
19. Serum creatinine \> 1.5 times the upper limit of the normal range.
20. AST, ALT, total bilirubin or alkaline phosphatase \> 2 times the upper limit of the normal range.
21. Serious underlying disease other than UC which in the opinion of the investigator may interfere with the subject's ability to participate fully in the study.
22. History of alcohol or drug abuse which in the opinion of the investigator may interfere with the subject's ability to comply with the study procedures.
23. Stools positive for clostridium difficile.
24. Pregnant or lactating women.
25. Prior enrolment in the current study and had received study treatment.
D: Inclusion Criteria:

1. Signed informed consent,
2. Men or women aged 18 to 75 years,
3. Active ulcerative colitis, except proctitis limited to 15 cm ab ano, confirmed by endoscopy and histology,
4. Established disease (presence of blood or mucus in the stools) or new diagnosis (bloody stools occurring at least during 14 days prior to baseline visit),
5. Clinical Activity Index (CAI) \>= 6 and Endoscopical Index (EI) \>= 4,
6. Women of child-bearing potential, if heterosexually active, have to apply a highly effective method of birth control, which is defined as those which result in a low failure rate (i.e., less than 1% per year) when used consistently and correctly such as implants, injectables, combined oral contraceptive method, some intrauterine devices (IUDs), sexual abstinence, or vasectomised partner. The investigator is responsible for determining whether the subject has adequate birth control for study participation.

9. Active colorectal cancer or a history of colorectal cancer,
10. Active malignancy other than colorectal cancer or treatment with anticancer drugs during the last 5 years. Patients with a history of cancer other than colorectal cancer and at least five years of uneventful follow up and no signs of recurrence may be eligible,
11. Immunosuppressants within 3 months and/or corticosteroids (oral, intravenous \[IV\] or topical rectal) within 4 weeks prior to baseline,
12. Current relapse occurred under maintenance treatment with \> 2.4 g mesalazine per day,
