MORPHOFUNCTIONAL INVESTIGATION OF BROWN BEAR (URSUS ARCTUS) STOMACH

Histological investigation and functional comment of the brown bear stomach structure wall and its comparison with another carnivorous as dog, fox, wolf, jackal, cat and tiger, respectively which were surveyed previously was the aim of this study. The stomach of a female brown bear after sudden death was obtained and slides by conventional histological method were examined microscopically and morphometry was done. In mucosal layer of the brown bear stomach as in other investigated canine species the subglandular layer stratum compactum was not established also, as opposed to feline species in which stomach's mucosa this specific collagenous layer was always presented.
