CHANGES IN HYSTOLOGICAL STRUCTURE OF SUPERFICIAL RENAL CORPUSCLE IN POSTPARTUM ONTOGENESIS OF SIBIRYAK-2 HENS

Abstract

The paper pays attention to the important role of histological research in investigating the organism, its tissues and processes occurred. The authors declare about a great variety of modern methods applied in histological research. They contribute to conducting structural and histochemical analysis of microscopic and sub-microscopic types. The researchers carry out histological investigations in birds of different physiological preferences, which inhabit different climatic zones; they point out cell changes in the structure of organs and tissues. The authors studied histological structure of kidneys of Sibiryak-2 hens aged 15–90 days; they found out changes in superficial renal corpuscles and specific features for each stage of development. Hens aged 15 days are characterized with increasing number of renal corpuscles and capsular teeth. Hens aged 30 days are characterized with increasing of number of renal corpuscles but their size is smaller in comparison with the hens aged 15 days; nuclei are located in a circumferential direction of glomerulus of the renal corpuscles whereas the Bowman capsular teeth is reduced significantly. The researchers observed increasing of the number of renal corpuscles in hens aged 60 days whereas there was no capsular teeth; hens aged 90 days experience increasing of renal corpuscles and reducing their size.
