title: [Pharmacological and toxicological studies of novoolean].
abstract: A toxicologic study and some pharmacologic investigations were carried out with the novobiocin salt of oleandomycin, formulated as novoolean. The LD50 of the of the preparation for i/m application to mice proved equal to 1500, and to rats--1800 mg per kg of body weight. For oral introduction the average lethal dose for mice amounts to 3250 mg/kg. At such route of application on deaths were observed in rats after the administration of 5 000 mg/kg. A 30-day treatment via i/m application to rats of 180 mg/kg (which is equal to one tenth part of LD50) did not lead to changes in the growth, blood picture, and a number of clinical and biochemical indices of the blood and urine; there were no changes in the development and the structure of the viscera as well as the reproductive capacity of the test animals. Electron-microscope studies with rats treated in the same period with 360 mg/kg (one fifth of the LD50 value) revealed certain injuries of the liver kidneys. With cats the venous infusion of the preparation at rates of up to 15 mg/kg showed no changes in the blood pressure and the rhythm and pulse rate, and the addition of novoolean to the nutrient solution in concentrations of up to 100 mg/cu. cm did not influence the tonus and the motor function of isolated (after Magnus) sectioned portions of the small intestine of rabbits and guinea pigs.
