Herbal Substance, Acteoside, Alleviates Intestinal Mucositis in Mice

الملخص EN

This study investigated the role of acteoside in the amelioration of mucositis.

C57BL/6 mice were gavaged daily with acteoside 600 μg for 5 d prior to induction of mucositis and throughout the experimental period.

Mucositis was induced by methotrexate (MTX; 12.5 mg/kg; s.c.).

Mice were culled on d 5 and d 11 after MTX.

The duodenum, jejunum, and ileum were collected for myeloperoxidase (MPO) activity, metallothionein (MT) levels, and histology.

Acteoside reduced histological severity scores by 75, 78, and 88% in the duodenum, jejunum, and ileum, respectively, compared to MTX-controls on d 5.

Acteoside reduced crypt depth by 49, 51, and 33% and increased villus height by 19, 38, and 10% in the duodenum, jejunum, and ileum, respectively, compared to MTX-controls on d 5.

Acteoside decreased MT by 50% compared to MTX-control mice on d 5.

Acteoside decreased MPO by 60% and 30% in the duodenum and jejunum, respectively, compared to MTX-controls on d 5.

Acteoside alleviated MTX-induced small intestinal mucositis possibly by preventing inflammation.
