ABSTRACT
Ahadian M, Saadatfar
Z, Ghodrati H., Macro and micro structural and enzyme
changes in embryonic liver of ostriches (Struthio camelus), Onl J Vet Res., 20(5):279-295, 2016. Changes in gross anatomy, histology and enzymatic
activity in 24 incubated eggs of ostriches at day 10, 13, 16, 22, 26, 30 and
36, and 1st day after hatching, are described. On day 10 of
incubation, livers appeared small yellow buds adjacent to heart with
hepatocytes in cord and acini with sinusoidal endothelial and kupffer cells. Reticular and collagen fibers appeared on
day 10 and at day 13, left and right lobes became apparent and day 16 liver was completed with
organized hepatic cords and even glycogen inclusions. By day 26 lipid droplets
appeared in hepatocytes and day 36 or 1st day after hatching,
hepatocytes were vacuolated. Lactate dehydrogenase decreased after day 22, ALT
increased after day 16 and the ALP between day 22 and 36. Conclusions are
supported with micro and macro anatomy imaging.
Keywords: Ostrich embryo, Liver, Morphogenesis,
Histology, Enzymes.
