Anatomical, histological and biochemical studies of desert rodent Gerbillus tarabuli (Thomas, 1902) kidney.

Abstract

The present work aimed to study the anatomy, histology, cytology and some biochemical parameters (urea, osmolality, haematocrit, serum natrium, serum kalium) of the kidney of Gerbillus tarabuli. The investigated animals (n=16) were collected from the desert, weighed and transferred alive to the laboratory in separate cages. A blood sample was taken by puncture at the retro-orbital sinus of each animal using a Pasteur-type capillary pipette capillary. They were anaesthetized with urethane injection (25%), after which they were carefully dissected; their organs were taken out and prepared for the histological and cytological studies. Pasteur pipette capillary type the kidney of the Gerbillus tarabuli is subdivided into three regions: Cortex (1193.625±60μm), Outer Medulla (1316.72±73μm), Inner Medulla (2525.08±85 μm). Pasteur pipette capillary type the kidney of the Gerbillus tarabuli is subdivided into three regions: Cortex (1193.625±60μm), Outer Medulla (1316.72±73μm), Inner Medulla (2525.08±85 μm). The concentration of the biochemical parameters of urea (0.41±0.02g/L), osmolality (300.75±3.33mOs/kg), haematocrit (34.18±1.3%), serum natrium (141.37±2.31mmol/L) and serum kalium (7.69±0.39mmol/L) is in the interval of the norm compared with several studies on desert and semi-desert rodents and also on the Wistar rat. These findings revealed the adaptive morphology and physiological function in the kidney of G.tarabuli to the desert environment.
