    (KAFKAS UNIV, VETERINER FAKULTESI DERGISI, 2020) Selcuk, Muhammet Lutfi; Colakoglu, Fatma; Tipirdamaz, Saadettin
    The objectives of this study were to determine renal volume, volume ratios in New Zealand rabbits by stereological methods, reveal the histomorphological properties of tubulus proximalis, tubulus distalis, collecting tubule, Henie's loop and number of glomerulus. Besides, it is to investigate the possible differences between the functional subcomponents of the right and left kidneys and the effects of gender discrimination on them. The study was carried out on 9 males and 9 females healthy New Zealand rabbits' kidneys. After weighing kidneys, diameters and lengths were measured with a digital caliper. Total kidney volume and volume fractions of subcomponents of left and right kidneys were estimated by Cavalieri's method. The histological section was taken from the sampled kidneys and kidney structures in the unit area were counted. After all values of each component were expressed as ratios with in kidney, they were analyzed statistically to reveal differences between sexes. There was no statistical difference between the renal densities. The right dorsoventral and mediolateral diameters of the females and males were found to be greater than the left (P<0.05). No statistical difference was found in volume measurements with Archimedes' principle and Cavalieri's method (P>0.05). It was determined that the number of left collecting tubules in female rabbits was higher than males and it was statistically significant (P<0.05). Obtained data by making sexual dimorphism will contribute to the existing anatomical knowledge accumulation.
