Productivity of spermatogenesis and the population of spermatogonial cells were substantially reduced in male Wistar rats 3 months after administration of cytostatic drug paclitaxel, damaging stem spermatogonia. However, signs of reparative regeneration appeared in the testicular tissue. In animals receiving paclitaxel in combination with granulocyte CSF,(More)
Pharmacological characteristics of somatotropin pegylated using electron-beam synthesis nanotechnology (PEG-STH) were studied. Oral PEG-STH stimulated the intensity of protein and lipid metabolism and endochondral bone growth without modifying the processes of periosteal and endosteal bone formation. Specific activity of this substance administered orally(More)
Hyaluronidase immobilized on polyethylenoxide obtained by electron bean synthesis was administered intranasally and intravenously to C57Bl/6 mice after intratracheal bleomycin and the enzyme effects on the development of pneumofibrosis in animals were studied. Intranasal immobilized hyaluronidase prevented connective tissue growth in the lungs exposed to(More)
Using the model of lung fibrosis induced by intratracheal administration of bleomycin we studied anti-fibrotic activity of combined treatment with neuroleptic haloperidol and hyaluronidase immobilized on polyethylene oxide using electron-beam synthesis. It was shown that successive administration of immobilized hyaluronidase and the neuroleptic drug(More)
Course treatment with IFN-α2b immobilized on polyethylene glycol stimulates phagocytic activity of peritoneal macrophages and neutrophils, enhances humoral immune response in CBA/CaLac mice, stimulates IL-4 synthesis, and suppresses IFN-γ production by mitogenstimulated splenocytes from experimental animals.
Effectiveness of the granulocyte colony-stimulating factor immobilized by using electronbeam synthesis nanotechnology was investigated on the model of experimental testicular failure caused by the toxic effect on stem spermatogonia. Administration of the drug to experimental paclitaxel-treated animals increased the number of sources of the proliferative(More)
The effect of immobilized hyaluronidase on stem and progenitor cells of the lungs was studied on the model of partially reversible toxic bleomycin-induced pulmonary fibrosis in C57Bl/6 mice. During the inflammation phase, immobilized hyaluronidase reduced infiltration of alveolar interstitium with hemopoietic stem cells Sca-1+, c-Kit+, CD34–, (CD3, CD45R(More)
Population of spermatogonia was reduced in 2, 3, and 6 months after single intravenous injection of antitumor drug paclitaxel in maximum tolerated dose (MTD). The count of Sertoli cell increased in 3 months after the start of the experiment. The maturity of the seminiferous tubule epithelium was lower than in intact rats. Spermatogenesis productivity did(More)
Antifibrotic activity of intranasally administered conjugates of pluronics L31 and F68 with hyaluronate-endo-β-N-acetylhexosaminidase was studied in C57Bl/6 mice under conditions of single and repeated bleomycin-induced injury to the alveolar epithelium. Conjugates were prepared using the technique of protein immobilization with ionizing radiation. We(More)
The possibility of boosting antifibrotic activity of testicular hyaluronidase immobilized on polyethylene oxide with spiperone was studied on the bleomycin models of a single (partially reversible pneumofibrosis) and repeated (irreversible pneumofi brosis) injuries to the alveolar epithelium in C57Bl/6 mice. The antifibrotic effect was more pronounced after(More)
