| Summary: | Indonesia has 205 species of bats that constitutes 21 % kind of the bats in
the world. Bat is divided into 2 subordo which are Megachiroptera &
Microchiroptera. Codot is the bats which included in the subordo of
Megachiroptera, the bat which eat fruits and nectar. While subordo
Microchiroptera is insectivorous bat. Research on the structure of duodenum
codot (Rousettus sp.) histology become important because of those differences.
Sample of this research was three dudenum codot that obtained from
region of Bantul. These sample was fixation, dehidration, clearing, and
embedding. Then followed by block cutting with 5-6 μm thickness. Staining was
done by using routine Hematoxylin-Eosin staining early confirmation of the
histological structure and Alcian Blue pH 2.5�Periodic Acid Schiff (AB pH 2.5-
PAS) was used to determinethe distribution of mucopolysaccharides in the
duodenum codot. Staining results analized with descriptive result analysis.
The histological structure of the duodenum codot (Rousettus sp.) has
similarity with such frugivore bats such Sturnira lilium and other mammals. Villi
of duodenum codot is short and branched. Lamina muscularis mukosae codot is
very thin because it is composed of only one layer of smooth muscle. Brunner
glands in the codot tunica submucosa fills the anterior portion of the duodenum.
Intestinum length has Brunner Glands is 4503.57 ± 4329.88 μm. Internus circular
lamina muscularis and externus longitudinal lamina muscularis has same
thickness as plexus myenterikus in between. Goblet cells in the epithelium and
kripte Lieberkuhn were acid because stained strong blue or positively reacted to
Alcian Blue staining while the columnar cell in the lamina epitelialis mukosae, the
columnar cell Kripte Lieberkuhn, and the Brunner glands in the tunica
submucosa were neutral because they were stained magenta or positively reacted
to the Periodic Acid Schiff staining.
