ABSTRACT
The protective capacities of fresh green (unripe) sweet bananas and of phosphatidylcholine and pectin (banana ingredients) against acute (ethanol- or indomethacin-induced) and chronic (indomethacin-induced) gastric mucosal lesions were evaluated in rats. Banana pulp was mixed with saline and given by gavage, as a pretreatment in a single dose. The identical protocol was used for pectin and phosphatidylcholine solution, and the dosages were adjusted to equal the amount of ingredients in the banana mixture, but higher concentrations were also given. The banana suspension reduced acute lesions, as did pectin and phosphatidylcholine in higher concentrations, but in concentrations as in fresh fruit no protective effects were observed except by pectin against indomethacin injury. In the model of chronic ulcers the banana suspension provided an incomplete and temporary protective effect. We conclude that the protective capacity of fresh green sweet bananas cannot be confined to only one active component. Pectin and phosphatidylcholine may protect gastric mucosa by strengthening the mucous-phospholipid layer, but the mechanism of protection afforded by bananas has to be further elucidated.
