Abstract
Banana pulp powder ( Musa sapientum Linn. var. paradisiaca) was studied for its effects on gastric mucosal resistance. Banana-treated (0.5 g/kg orally, twice daily for 3 days) rats of either sex showed: (i) a significant increase in the [ 3H]thymidine incorporation into mucosal cell DNA; (ii) a significant increase in the total carbohydrate (sum of total hexoses, hexosamine, fucose and sialic acid) content of gastric mucosa; (iii) a significant decrease in gastric juice DNA and protein; (iv) a significant increase in the total carbohydrates and carbohydrate/protein ratio of gastric juice. Aspirin treatment to rats caused similar effects as banana on the [ 3H]thymidine incorporation into mucosal cell DNA but showed opposite effects on the other parameters. These results suggest that banana treatment increased and aspirin decreased the gastric mucosal resistance as evidenced by a respective decrease and increase in gastric juice DNA, the latter serving as an index of the rate of mucosal shedding. Increased cellular mucus may be the factor for increased mucosal resistance. The results of the present study tend to confirm that plantain banana powder strengthens mucosal resistance and promotes the healing of ulcers.
