The article shows down the results of histological researches of the femoral bone parts, which situated under bone cartilage. The method of manufacture of histopreparations is described. In article also describes the microscopic changes of bone tissue, which was observe. It is noted that knee joint osteoarthrosis is characterized not only by morphological changes of articular cartilage, but also by quite distinct microscopic changes below the position of bone tissue. In article is described that the axillary resorption of bone tissue and single cells of fibrous osteodystrophy is recorded microscopically in the femoral bone. [ABSTRACT FROM AUTHOR]

The results of the research on histostructure thyroid gland of red pigs with a white belt under different conditions of feeding. To perform the planned research animals were divided into 3 groups: First group - normal feeding; Second group - feeding 25% above normal; Third group - feeding 25% below normal. Samples for thyroid research were taken at slaughter pigs at the age of 2, 4, and 6 months at live weight of 120kg. Experimental animals were slaughtered in the morning before feeding. The research results of histological elements of structure of thyroid gland the pigs suggests that growing feeding levels affected the functional state of the thyroid gland. In pigs when they reach a live weight of 120kg follicular diameter of the thyroid is 122,7 ± 4,1mkm - for pigs normal feeding; 128,7 ± 4,5 mkm - feeding 25% above normal; 118,4 ± 4,3 mkm - feeding 25% below normal. Based on the data obtained can be noted that the pigs that were grown at elevated feeding, activity of the thyroid gland is higher. Research on height of thyroid follicular epithelium in all experimental animals increases to 4 months of age, followed by a gradual decline. A particularly sharp increase in the follicular epithelium height was observed in pigs of intensive feeding level. Based on the data obtained can be noted that the pigs feeding 25% higher activity of the thyroid gland is higher. [ABSTRACT FROM AUTHOR]

A certain dependence of physiological, morphological, histological parameters of the skin and wool productivity of sheep of different genotypes. Studied the histological features of the skin of sheep of different genotypes. It is found that sheep Tavrian type characterized finer wool, the greater thickness of the epidermis and a thin layer of the dermis itself, compared with the line 100 Ascanian tonkorunnoj breed.
