Abstract

Microvascularization of domestic fowl kidneys was studied using scanning electron
microscopy (SEM) of vascular corrosion casts (VCCs). Two types of nephrons,
mammalian-type
(MT) and reptilian-type
(RT) nephrons and their glomerular structure
were analysed quantitatively by 3D morphometry. A significant difference in
shape and size between the MT and RT glomeruli was found. The mean diameter of
the RT glomeruli was about 56 μm, while that of MT glomeruli was significantly larger,
namely about 80 μm. The afferent arterioles in mammalian-type
glomeruli usually
bifurcated into two lobular branches and formed a complex glomerular capillary network
with numerous loops. Reptilian-type
glomeruli consisted of a single capillary
forming few loops and leaving the glomerulus as efferent arteriole. Diameters of afferent
and efferent arteriolar replicas were similar in all three kidney divisions of
MT and RT nephrons. The absence of the interconnecting branches between the
MT nephron capillaries at the gross inspection suggests that the mammalian-type
nephron glomeruli, although more complex than the reptilian type, are not equivalent
to those in mammalian kidneys.
