Abstract

Background/aims: The effects of short-chain fatty acids and glutamine on diseased colonic mucosa, such as in inflammatory bowel disease, are not well described. The aim of this study was to investigate the role of L-glutamine and short-chain fatty acids, both via enema and oral administration, on mucosal healing in experimental colitis. Methods: Colitis was induced with trinitrobenzenesulphonic acid in ethanol enema in rats. Saline enema (Colitis group, n: 12), L-glutamine enema (n: 12), short-chain fatty acids enema (n: 12), oral L-glutamine (n:11) and oral short-chain fatty acids (n.11) were applied twice daily for 10 days after induction of colitis. The sham group (n: 12) received only saline enema. Rats were sacrificed at the tenth day. Crypt depth and DNA content were measured in colonic mucosa. Results: Crypt depth was significantly greater in both glutamine groups and short-chain fatty acids enema group than in sham and colitis groups (p<0.05). The mucosal DNA contents of the colitis and glutamine enema groups were significantly greater than both short-chain fatty acids groups (p<0.05). DNA content in the oral glutamine group was significantly greater than in the short-chain fatty acids enema group (p<0.05). Conclusions: L-glutamine enema can accelerate mucosal healing and regeneration in experimentally induced colitis in rats. When compared to glutamine in this study, shortchain fatty acids showed no beneficial effect on colitis.

Özet

Amaç: ‹nşamatuvar barsak hastalığı gibi hastalıklı kolon mukozası na kısa zincirli yağ asidi ve glutaminin etkileri tam olarak aydınlatılamamıştır. Bu çalışmanın amacı deneysel kolitte L-glutamin ve kısa zincirli yağ asidi kokteyli lavmanı ve oral uygulamalarının kolon mukozası iyileşmesine etkilerini incelemektir. Gereç ve yöntem: Çalışmada sıçanlarda etanol içinde trinitrobenzensülfonik asid lavmanı ile kolit oluşturuldu. Gruplar; Serum fizyolojik lavmanı (Kolit grubu, n: 12), L-glutamin lavmanı grubu (n: 12), kısa zincirli yağ asidi lavmanı grubu (n: 12), oral l-glutamin grubu (n: 11) ve oral kısa zincirli yağ asidi grubu (n: 11) şeklinde idi. Lavman solusyonu kolit oluşturulduktan sonra on gün süre ile günde iki kere uygulandı. Sham grubunda kolit oluşturulmadan sadece serum fizyolojik lavmanı uygulandı (n: 12). Onuncu gün sakrifiye edilen sı- çanlarda kolon mukozasındaki kript derinliği ve mukozal DNA içeriği ölçüldü. Bulgular: Kript derinliği her iki glutamin grubu ve kısa zincirli yağ asidi lavmanı gruplarında sham ve kolit gruplarından fazla bulundu (p < 0.05). Mukozal DNA içeriği kolit ve her iki glutamin gruplarında kısa zincirli yağ asidi gruplarına göre daha fazla idi (p < 0.05). Oral glutamin grubu mukozal DNA içeriği de kısa zincirli yağ asidi lavmanı grubundan daha fazla idi (p < 0.05). Sonuç: Sıçanlarda deneysel kolitte L-glutamin mukozal iyileşme ve regenerasyonunu hızlandı rabilmektedir. Kısa zincirli yağ asidi kokteyli ise bu çalışmada glutamin kadar etkili bulunmamıştır.
