The effects of functional pinealectomy on the morphological organization of the regional lymph nodes in the liver of rats were studied. Shrinkage of follicles (with increased percentage of germinative centers in them) and reduced count of mature lymphoid cells in the medullary cords indicated more intense migration of B cells from these B-dependent zones.(More)
The effects of melatonin, aluminum oxide, and polymethylsiloxane complex on the expression of LYVE-1 (lymphatic vessel endothelial hyaluronan receptor) in the liver were studied in db/db mice with experimental obesity and type 2 diabetes mellitus. The complex or placebo was administered daily by gavage from week 8 to week 16 of life. The animals receiving(More)
Histological study of structural transformations in the thymus of Wistar females in induced carcinogenesis (N-methyl-N-nitrosourea injection in the right 2-nd mamma) and polychemotherapy (6 months after tumor growth initiation; cyclophosphamide, methotrexate, and 5-fluorouracyl) was carried out. The area of the cortical matter in the thymus decreased 6(More)
Morphological changes in the thymus of female Wistar rats with experimental mammary gland carcinomas were studied. After adjuvant therapy, the area of the cortical matter and density of parenchymal cells in the thymus decreased, while areas of the medulla, connective tissue, and content of immunoblasts and macrophages increased. In the thymuses of rats(More)
We studied the effect 24-h illumination on quantitative and qualitative parameters of the bone marrow cells in Wistar rats. It was shown that desynchronosis reduced the release of nucleated cells from the femoral bone, while melatonin weakened this effect. The number of bone marrow mesenchymal stromal cells was resistant to circadian rhythm disturbances,(More)
