ABSTRACT

Purpose:

To compare the effects of vitamin E and 1 percent methylen blue solutions on prevention of experimentally induced adhesions in rats.

Methods:

Thirty seven female Spraque Dawley rats were randomized into four groups. First group was kept as sham operated group. An adhesion model was constituted on the left uterine horn of the other groups. The lesion areas of rats from the second, the third and the fourth groups were coated with 2 ml 0.9 percent saline solution (C group), 10 mg vitamin E (VE group) and 1 percent methylen blue solutions (MB group), respectively.

Results:

Histopathologically, adhesion scores, mononuclear cell infiltration, oedema and fibrosis were more prominent in the MB group compared with C and VE groups. There were no significant differences between the groups in tissue glutathione peroxidase (GPx), catalase (CAT) activities and glutation (GSH) level, these parameters were slightly increased in group with VE supplementation though. The administration of VE and MB significantly decreased NO (P<0.01) levels when compared to the C group. The level of malondialdehyde (MDA) in the VE group was significantly lower (P<0.05) than those of the Sh and C groups.

Conclusion:

Intraperitoneal methylen blue solutions treatments were more effective according to vitamin E in preventing the formation of intra-abdominal adhesion in a rat uterine horn model.
RESUMO

Objetivo:

Comparar os efeitos da vitamina E e 1 por cento da solução de azul de metileno na prevenção de aderências induzidas em ratos.

Métodos:

Trinta e sete ratos fêmeas Spraque Dawley foram distribuídos em quatro grupos. O primeiro grupo foi mantido como grupo sham. O modelo de aderência foi realizado no corno uterino esquerdo nos outros grupos. As áreas da lesão dos ratos do segundo, terceiro e quarto grupos foram revestidas com 2 ml de solução salina 0,9 por cento (Grupo C), 10 mg de vitamina E (Grupo VE) e solução de azul de metileno 1 por cento (Grupo MB), respectivamente.

Resultados:

Histopatologicamente, o escore das aderências, infiltração celular mononuclear, edema e fibrose foram mais proeminentes no grupo MB em comparação aos grupos C e VE. Não houve diferença significante entre os grupos na peroxidase da glutatione do tecido (GPx), atividade da catalase (CAT) e o nível de glutation (GSH). Estes parâmetros foram ligeiramente aumentados no grupo com suplemento da VE. A administração da VE e do MB diminuiu significantemente os níveis quando quando comparada ao Grupo C. O nível de malondialdeído no grupo VE foi significantemente mais baixo do que nos grupos sham e C.

Conclusão:

A administração intraperitoneal da solução de azul de metileno foi mais eficaz de acordo com a vitamina E na prevenção de aderências intra-abdominais no corno uterino de ratos.
