: p<0.05, significant difference compared to fed groups.

Mucosal height and cell number are higher in aged group at base line (p<0.05), which significantly decreases after starvation in both groups (p<0.05). The relative change of mucosal height and cell number were significantly different between the aged and adult groups 48 hours after starvation.
