ABSTRACT
Efficacy and safety of unasyn, a combination of sulbactam and ampicillin, was studied in the treatment of 66 patients with infections of the urogenital organs. The drug was administered intramuscularly, intravenously and orally. The treatment course averaged 7-14 days. The dose of the drug for the intravenous and intramuscular administration was 1.5-3 g 4 times a day and that for the oral administration was 0.75 g 2 times a day. The strains of gram-positive cocci, Escherichia coli and Proteus spp. proved to be highly sensitive to the drug: 80-83, 43 and 53 per cent of the sensitive strains respectively. 25-75 per cent of the strains showed beta-lactamase activity that was most frequently detected in Proteus spp. and Staphylococcus spp. The maximum concentrations of ampicillin and sulbactam determined by liquid chromatography were respectively 18 +/- 5.7 and 11 +/- 2.42 micrograms/ml in the blood and 700 and 350 micrograms/ml in the urine. A satisfactory bacteriological effect of the treatment was observed in 93 per cent of the cases. A complete elimination of the initial pathogens was stated in 57-73 per cent of the cases. No side effects were recorded.

A panel of 22 hybridomas producing monoclonal antibodies (McAb) to C. psittaci was obtained. 15 hybridomas produced IgG1 antibodies, 4 hybridomas produced IgM antibodies and 3 hybridomas produced IgG2b, IgG3 or IgA antibodies. IgG1 antibodies and 2 IgM antibodies did not bind complement in the complement fixation test. All McAb were reactive in the enzyme immunoassay and the indirect immunofluorescence test and did not precipitate specific antigens. Peroxidase conjugates on the basis of McAb effectively detected Chlamydia antigen, prepared from the crude suspension of chick embryo yolk sack infected with different strains of C. psittaci and C. trachomatis, in different modifications of EIA.

Unasyn is a combination of ampicillin, a bactericidal antibiotic, and sulbactam, an inhibitor of beta-lactamases. It was used in treatment of 36 patients with urogenital infections. The combination was administered intravenously and in the main intramuscularly. The treatment course amounted to 7-10 days. The average daily dose was 6 to 9 g. 22 patients with acute nonocclusive pyelonephritis were treated with the combination and its clinical and bacteriological efficacy was stated in 95 per cent of the cases. An excellent clinical effect of the combination was observed in 6 patients with acute epididymitis. A clinical improvement was also observed in the treatment of the patients with acute prostatitis and chronic renal infections. Unasyn proved to be a highly efficient antibacterial combination with regard to gram-positive flora and colon bacilli as representatives of gram-negative organisms. Satisfactory results were also stated in the treatment of infections caused by Proteus spp. Complete elimination of the pathogen was achieved in 57.7 per cent of the cases. No adverse reactions to Unasyn except pain in the site of the injection were recorded.
