碩士 === 國立中興大學 === 獸醫學系 === 85 === Ito cells are located in the space of Disse closely contact
with hepatocytes or distribute in the hepatic parenchyma between
hepatocytes, it play multiple physiological and pathological
roles. In order to obtain more histological and ultrastructal
informations of Ito cells ,and the relationships with
hepatocytes, endothelial cells, and Kupffer cell, the livers of
pigs, dogs, rabbit, rats, mice, chickens, ducks, geese were
studied , and the normal condition of these organs were proved
by hepatic fuctional tests.Quantitative analysis of Ito cells
was studied by examing liver semithin(1μm) sections, which were
stained by 1%toluidine blue, and counting the number of Ito
cells per 100 hepatocytes of various animals, and the results
were evalvated by "Completely randomized design; CRD" in
Statistics. The results showed that swine hepatic lobules
were significantly higher than that of other animals, and the
connective tissue which surrounded the hepatic lobule was also
more abundant than others. The mean area of central vein in
rodent was significantly higher than that of other animals
(P<0.05). The size of sinusoid in dog was the largest .The ratio
of Ito cells per 100 hepatocytes of avian liver was signficantly
higher than rodent and mammalian species (P<0.001). Species
difference between hepatocytes and the number of Ito cells were
primarily dissimilarity in the main ultrastructural features.The
number of lipid droplets of the Ito cells were different in all
species studied. Conclusively,the ultrastructure of the liver
in all species studied were different, and the number of Ito
cells were abundant in avain species. According to the results,
it was suggested the relationship of production fatty liver
between the numbers of Ito cells in avain species.
