Effect of calabash chalk on the histomorphology of the gastro-oesophageal tract of growing wistar rats.

Background: Calabash chalk is a naturally occurring mineral consumed by members of some Nigerian communities for pleasure and by pregnant women as a remedy for morning sickness. The consumption of this geophagic material motivated our interest on the effect of the chalk on the histomorphology of the gastro-oesophageal tract.

Methods: Twenty-eight young Wistar rats, 4 weeks old, were divided into 4 groups of equal size.
