It is established that Wistar rat testes demonstrate stable morphological changes attended by a diminishment of the stem cell population, depletion of the other layers of the spermatogenic epithelium, a decrease of the number of tubules with meiosis stage XII, and intensified desquamation of epithelial cells during 30 days after administration of(More)

Preclinical study of the safety of 6 preparations containing ultralow doses of antibodies to endogenous regulators showed that they are relatively safe, are well tolerated by animals in doses more than 1000-fold surpassing the therapeutic dose for humans, and produce no general toxic effect on the organism of laboratory animals.
Single intravenous injection of paclitaxel to rats in a maximum tolerated dose of 4.6 mg/kg was accompanied by permanent structural and functional changes in the liver. The observed changes were typical of nonspecific reactive hepatitis: infiltration with lymphocytes and macrophages, pyknosis, and focal fatty degeneration of hepatocytes. Liver enzyme(More)
We studied the mechanisms of therapeutic effects of granulocytic colony-stimulating factor in experimental diabetes mellitus. It was found that this preparation increased the number of mesenchymal precursor cells in the bone marrow and peripheral blood with subsequent increase in the content of progenitor cells in the pancreas. These results attest to(More)
We studied toxicity of a new Russian radiopharmaceutical Nanocolloid, 99mTc-Al2O3. Tests for acute toxicity showed that this agent belongs to a class of moderate-toxicity substances and does not have cumulative properties. The evaluation of subchronic toxicity after subcutaneous injection of this product to rats (0.04, 0.2, and 0.4 ml/kg) and rabbits (0.02(More)
High hepatoprotective activity of granulocytic CSF and hyaluronidase immobilized using electron-beam immobilization technology was demonstrated on the model of CCl4-induced hepatitis: the preparations produced anticholestatic, anti-inflammatory, and antisclerotic effects. These effects developed against the background of stimulation of bone marrow(More)
Intramuscular injections of Relatox in therapeutic and toxic doses to young outbred laboratory rats for 14 days caused no changes in the peripheral blood and bone marrow parameters, serum biochemical parameters, and morphology of the major viscera. In the toxic dose, the drug caused local irritation (inflammation, atrophy, and sclerosis in muscle tissue).(More)
The effect of immobilized granulocyte CSF on morphological characteristics and functional state of the liver was studied during chronic toxic hepatitis. The mechanisms of the therapeutic action of this agent were evaluated. The product had a strong hepatoprotective effect and exhibited the antiinflammatory and antisclerotic properties. The mechanism of(More)
