[Pharmacological and clinico-pharmacological studies of a combination preparation for calves having antianemia and general tonic action].

A combined preparation, biofer, was studied, defining its clinical and pharmacological capacity. Featuring in its composition are: normal bovine gammaglobulin, 8.0 g; ferridextran (dextrofer-100), 32 cm2 (= 3.2 g Fe); cuprum sulfuricum, 0.32 g (= 0.08 Cu); Co chloride, 0.18 g (= 0.08 Co); cyancobalamin, 0.0032 g; and protein hydrolysate up to 100 cm3, at pH = 7.0-7.2. The local and total tolerance of animals for biofer was studied along with the acute toxicity, absorption, and retention in the body of test animals and calves as well as the antianemic action in albino mice and calves. It was found that at 4 degrees C to 8 degrees C the shelf life of biofer was 2 years. Its LD50 at subcutaneous injection to albino rats was 11.7 cm3/kg body mass. At the rate of 0.6 cm3/kg (i/m) rabbits did not manifest local and total intolerance; at 1.8 cm3/kg there was no local inflammation, however, a transient drop of appetite was seen; at 3 cm3/kg rabbits manifested intoxication with exitus. At i/m introduction to rabbits and calves biofer was more slowly absorbed than dextrofer-100. The liver and spleen of animals injected with biofer showed higher values for copper. In i/m application to anemic albino rats biofer showed a better antianemic effect than dextrofer-100. In calves it activated to a better extent both erythropoiesis and leukopoiesis.

[Potentials for the combined use of gentamycin with gamma globulin and vitamins].

Rabbits and pigs were used to study the resorption and retention of gentamycin dissolved in swine gamma globulin, swine polyglobulin, in water (gentamycin ampoules) and as a combined preparation with gamma-globulin and vitamins (gentaglobin). It was found that the protein solutions of gentamycin as compared to the water solutions at i/m application to rabbits and pigs give higher and persistent concentrations in the blood serum. At muscular application to pigs at the rate of 0.002/kg gentaglobin was retained in bacteriostatic concentrations in the blood serum for 12 hours. In pigs the gentamycin preparation, no matter what solvent was used, was eliminated comparatively very quickly through the bile and urine. It is stated that the quarantine for gentaglobin-treated pigs intended for slaughter should be 72 hours, the kidneys of such animals being excluded from human consumption. Gentamycin in the gentaglobin preparation has been found to retain its activity in the course of one year at +4 degrees C.

[Sensitivity of microorganisms isolated from swine to aqueous and proteinic solutions of gentamycin].

Employing a microbiologic method (in vitro) the activity was investigated of Gentamicin DSO Pharmachim, dissolved in water, in normal swine gamma-globulin, and in normal swine polyglobulin with regard to swine strains of Escherichia coli, Salmonella choleraesis Bordetella bronchiseptica, and Pseudomonas aeruginosa as well as Mycoplasms. A strong sensitivity was found to exsist in all tested strains (except for the Mycoplasms) to gentamycin both in a water and in a protein solution. The in vivo testing of the therapeutic effect of the two types of solutions in an experimental infection in albino mice revealed that the differences found in the activity of the various gentamicin solutions were statistically insignificant. The step agglutination test was used to follow up the effect of gentamycin on the OK agglutinating antibodies of a gamma-globulin preparation against oedema disease in pigs. Results showed a slight increase in the agglutinating activity of the gamma-globulin antibodies under the effect of the antibiotic.

[Gentamycin binding with blood proteins].

An 'in vitro' microbiologic method was employed to follow up the activity of gentamycin diluted in bovine and swine sera and bound to proteins isolated from them, in the course of continuous storing. It was found that the protein solutions of gentamycin retain their activity for one year under refrigerator conditions (4 degrees C), whereas with the freeze-drying of these solutions storage could be effected at room temperature. It was established through the method of balanced dialysis that gentamycin binds with the proteins of swine sera, and to a largest extent with native serum (30 per cent) and to a lower one--with globulins (15--16.2 per cent). The protein complexes of gentamycin proved entirely reversible and the process of binding was shown to have no influence on the minimal bacteriostatic concentration of the antibiotic with regard to Bacillus mycoides HB2.

[Experimental study of a combination preparation of a ferrodextran complex, gamma-globulin, trace elements and vitamins].

A combined preparation was produced, containing the Bulgarian ferrodextran complex, edema-disease gamma-globulin, microelements (Co, Mn, Cu), and vitamins (B1, B6, PP), pro uso veterinario. It was found that the product (B-50), kept under ordinary conditions in the course of one year, does not change its physicochemical properties and is not distinguished substantially by toxicity (Fe3+/kg liveweight) from the initial ferrodextran complex, but is resorbed more slowly following its muscular application to rabbits. B50 combines the properties of the fast-resorbing ferrodextran preparations giving slight local coloration with those of preparations having antianemic, growth-stimulating, and resistance enhancing effects.
