A Comparative Histomorphometric Study of the Stomach of Rat (Rattus norvegicus), Bat (Eidolon helvum) and Pangolin (Manis tricuspis) in Relation to Diet

| Sumario: | This study verified the comparative histomorphometric adaptations in the stomach of rat, bat and pangolin in relation to diet. Ten rats, ten bats and ten pangolins of both sexes were used for this investigation. The animals were sacrificed after slight anesthesia under chloroform inhalation. The stomach were excised, fixed in 10% formol saline and processed for light microscopic study. Stained slides were also subjected to morphometric analysis at a magnification of 400x. The results revealed that the cellular diameter/ density of parietal and zymogenic cells are significantly different in the three mammals (p<0.05) with the exception of the diameter of the zymogenic cells in pangolin which was not statistically significant (p>0.05) when compared with that of rat. Also, histological analysis revealed slight differences in the pattern of organization and distribution of connective tissue fibers. All these observations were reflections of the different pattern the stomachs of the three mammals have adopted to cope with their respective diets. |
