ABSTRACT

PURPOSE:

To investigate the effect of enemas containing probiotics and budesonide on the colonic mucosa in experimental colitis.

METHODS:

Fifty male Wistar rats with experimental colitis induced by 10 percent acetic acid enema were randomized to five groups (10 rats each) according to the treatment group 1 - saline solution, group 2 - budesonide (0.75 mg/kg/day), group 3 - probiotics (1mg/day), group 4 - probiotics plus budesonide, and group 5 - control, with not-treated rats. The following variables were studied body weight, macroscopic and microscopic score of the colonic mucosa, and DNA content of the mucosa.

RESULTS:

All animals lost weight between the beginning and the end of the experiment (280+ 16 mg versus 249+21 mg, p< 0.001). There was no significant difference among the groups in relation to both the macroscopic and histological score. The budesonide + probiotic group showed higher DNA content than control group (1.24+ 0.15 versus 0.92+ 0.30 mg/100mg of tissue, p=0.01).

CONCLUSION:

Budesonide in addition to probiotics enhance the mucosal trophism in experimental colitis.
RESUMO

OBJETIVO:

Investigar o efeito da administração retal de probióticos e budesonida na mucosa colônica de ratos com colite experimental.

MÉTODOS:

Cinquenta ratos Wistar com colite experimental induzida pelo ácido acético à 10 por cento foram randomizados em 5 grupos (n=10 por grupo) para diferentes tratamentos grupo 1 - solução fisiológica; grupo 2 - budesonida (0,75mg/kg/dia); grupo 3 - probióticos (1 g/dia); grupo 4 - probióticos associados a budesonida; e finalmente grupo 5 - controle, composto por ratos sem tratamento. As seguintes variáveis foram estudadas peso corporal, aspecto macroscópico e microscópico da mucosa e conteúdo de DNA da mucosa colônica.

RESULTADOS:

Todos os animais perderam peso entre o início e o fim do experimento (280±16 vs 249±21g; p<0.001). Não houve diferença estatística significativa entre os grupos em relação a macroscopia e histologia. O grupo budesonida + probiótico apresentou conteúdo de DNA maior que o grupo controle (1,24±0,15 versus 0,92±0,30 g/100g de tecido; p=0,01).

CONCLUSÃO:

A associação de budesonida com probióticos acelera o trofismo mucoso na colite experimental.
