HISTOLOGICAL AND ULTRASTRUCTURAL STUDY OF THE KIDNEY IN ONE – HUMPED CAMEL (Camelus dromedarius)

The current study was carried in the college of Veterinary Medicine-University ofBasrah for observing the histological and ultrastructural of the kidney in one-humpedcamel. In this study 10 adult healthy kidneys of one-humped camel bought fromslaughterhouse of Al-Samawah city, (2-3) years in summer (2020). The histologicalstudy include 5 kidneys investigated by using histological methods, the samples werefixed with 10% formaldehyde solution. Three stains were used H&E, PAS and Mallory.Five kidneys were used for ultrastructural study, samples were then processed forultrastructural technique. The histological examination show that high number of longloops of Henle and vasa recta in the kidney and the density percentage of renalcorpuscles more in the midcortical region than in a juxtamedullary region and thediameter of renal corpuscle was nearly similar in midcortical and in juxtamedullaryregion. The nephron was investigated by transmission electron microscopy is unique inhaving thick basal lamina, the thickest being found in part of the parietal layer ofBowman, s capsule and the thin loop of Henle. The characteristics above showed thatthe one – humped camel ͗s kidney possessed a high reabsorption and hence promotingthe production of high concentrated urine. The current study was aimed to report someof the histological and ultrastruchural characteristics of the kidney in normal state toprovide basic data which will utilized in the other studies.
