The diameters and densities of parietal and zymogenic cells were measured from slides stained with H&E.
The diameter of the zymogenic cells were also observed to be largest in rat (1.6 [+ or -] 0.26) as compared with 1.5 [+ or -] 0.20 and 0.8 [+ or -] 0.06 in pangolin and bat respectively (Table I).
The stomach of the pangolin and rat are characterized with numerous gastric pits with the zymogenic cells located towards the base of the gland, the parietal cells along the length and the mucus-secreting cell at the luminal surface (Fig 1a & b).
The same observation was evident in the zymogenic cells except for the cellular diameters in pangolin (1.5 [+ or -] 0.20 [+ or -]m) which was not significantly different (p>0.05) when compared with that of rat (1.6 [+ or -] 0.26 [+ or -] m) (Table I).
Also, the zymogenic cells were observed to be well arranged at the base of the gastric gland.
