OBJECTIVES: To evaluate the beneficial effects of spirulina on the treatment of experimental colitis.

BACKGROUND: Spirulina, a planktonic blue green algae from oascillateriaceae family, has anti-inflammatory, antioxidant, antitumor, anti-viral, and antimicrobial effects, rendering it a natural drug of prophylactic and therapeutic properties. The effects of spirulina on colitis are not known.

METHODS: Wistar rats weighing 200-300 g were used. Experimental colitis was created during anesthesia using the trinitrobenzene sulfonic (TNBS) acid. The rats were randomly divided into the 3 groups. In the group 1 (sham; n = 8), saline was administered via oral gavage 7 days after 1 ml of rectal saline was administered. In the group 2 (experimental colitis + spirulina; n = 8), 2 g/kg spirulina was administered via oral gavage 7 days after the rectal 1 ml TNBS was administered. In group 3 (experimental colitis; n = 8), enema was administered via oral gavage 7 days after the rectal 1 ml TNBS was administered. Eight days after the instigation of TNBS colitis, the rats were sacrificed and blood and tissue samples were taken. Histopathologic and immunohistochemical evaluations were conducted, and malondialdehyde (MDA), advanced oxidation protein products (AOPP), catalase (CAT), total antioxidant status (TAS), and glutathione (GSH) levels were determined.

RESULTS: Inflammation on mucosa and submucosa, hemorrhage, necrosis, cellular infiltration and crypt abscess formation, immunoreactivity and tissue MDA levels were decreased in the experimental colitis + spirulina group when compared to the experimental colitis group (p<0.05).

CONCLUSION: The results of the present study indicate the beneficial effects of spirulina on TNBS-induced inflammatory bowel disease (Tab. 6, Fig. 10, Ref. 40).
