Olemorphocycline treatment of calculous and noncalculous pyelonephritis]

40 patients suffering from calculous and non-calculous pyelonephrits were treated with olemorphocycline administered intravenously in a dose of 250 00 Units 2 times a day for 5--7 days. The clinical effect was observed in 62.5 per cent of the cases. In 54.7 per cent of the cases the isolates were resistant to oleandomycin and morphocycline. The kidney tissue and urine from the kidney pelvis taken during surgical operations of 20 patients were plated out. Staphylocci were most often detected in the platings of the kidney tissue. The microflora of the urinary bladder before the treatment and that of the urine from the kidney pelvis and the kidney tissue taken during the surgical operation was mainly ident     

Effect of proteolytic enzymes on antibiotic distribution when the preparations are administered by different routes]

The effect of proteolytic enzymes, such as terrilitine and chymotripsin on pharmacokinetics of morphocycline and streptomycin in rats after their administration by various routes was studied comparatively. The oral use of the enzymes or their introduction directly into the duodenum simultaneously or 30 minutes before the antibiotic administration did not increase the morphocycline and streptomycin levels in the biosubstrates tested. A tendency to a decrease in the serum and organ levels of the antibiotics in animals when used orally in combination with the enzymes was noted. When the drugs were administered intramuscularly, the morphocycline serum and organ levels in the rats increased insignificantly, while the streptomycin levels increased significantly. Administration of formalin as a stressor had an analogous effect which provided a supposition of a possibility of non-specific effect of the enzymes of distribution of the antibiotics on intramuscular injection of the enzymes in large doses having a local irritating effect.     

Interaction of morphocycline with beryllium ions]

Behaviour of morphocycline (H5R) and its complex with beryllium ions in acqueous solutions was studied fluorimetrically. The ionization constants of H5R were estimated at pH 1.5-15 according to the data of fluorimetric determination with respect to OH-group: pK1 6.40, pK2 8.25, pK3 10.65, pK4 11.30. Two constants characterizing the deprotonization process with respect to the carbonylic group and nitrogen were also estimated: pK01--1.0 (greater than C = 0) and pK02 4.75 (--N=). Formation of an intensively fluorescing compound less than [Be3(OH)3(H2O2)5]2HR greater than 2+ was observed at pH 6.0-7.0. The cause of such intensive fluorescence was deformation of ion [Be3(OH)3(H2O)6]3+ because of its exclusion from the coordinating sphere of one molecule of water during the complex formation and decreasing of level H comes from II as compared to the morphocycline level II comes from n. A procedure for detecting morphocycline in the blood of humans and animals was developed.     

Antibiotic resistance of Pseudomonas aeruginosa strains isolated from patients with infected burns

Sensitivity to 15 drugs of 248 P. aeruginosa strains isolated from patients with infected burns was studied by the method of agar dilution. All of the strains were resistant to polymyxin M, ceporin, erythromycin and oleandomycin. Most of the strains were resistant to streptomycin, monomycin, ampicillin and rifadin. Moderate resistance of the strains to carbenicillin, morphocycline, vibramycin, kanamycin, tetraolean and tetracycline was observed: the maximum concentrations of these antibiotics (128 microgram/ml) inhibited the growth of 85, 69, 63, 51.8, 43.6 and 41.2 per cent of the strains respectively. Gentamicin proved to be most active against the strains of P. aeruginosa and inhibited 87 per cent of the strains when used in the therapeutic doses. The study provided recomendation of the drugs for parenteral and local use in treatment of burns infected with P. aeruginosa.     

Study of the effect of tetracycline carboxamide derivatives on the cardiovascular and urinary systems]

The effect of tetracycline carboxamide derivatives, such as morphocycline, glycocycline and reverin on the cardio-vascular and urinary systems was studied on 24 rabbits using clinico-physiological and pathomorphological methods. The experiment was accounted for 7 days. When the drugs were administered in doses of 5 mg/kg, the changes in the indices of hemodynamics, respiration and bioelectric activity of the myocardium were rather of the same type. They were evident from decreased arterial pressure, slower rate of the pulse and respiration, lower voltage of peaks R and T, prolongation of intervals T--P and R--P, shifts in segment S--T from the isoelectric line. The changes took place by the 2nd and 5th minutes after the drug administration. Beginning from the 10th minute the hemodynamic indices returned to the initial values. By the level of the drugs effect on the above indices the antibiotics may be arranged in the following order: morphocycline, glycocycline and reverin. No effect of the antibiotics on the urinary system was noted.     

Action of tetracyclines on the pseudotuberculosis microbe in vitro experiments and their effectiveness in experimental pseudotuberculosis in white mice]

227 out of 228 strains of pseudotuberculosis microbes studied in vitro proved to be sensitive to tetracyclines. The MIC of tetracycline and morphocycline ranged within 0.25--25 gamma/ml. The MIC of chlortetracycline and oxytetracycline was somewhat lower, i. e. 1--50 gamma/ml. When administered intramuscularly all the tetracyclines had pronounced therapeutic effect in experiments with albino mice infected with the antibiotic sensitive strains of J. pseudotuberculosis. Chlortetracycline proved to be the most active drug in treatment of albino mice per os.     

Comparative study of the biological activity of tetracycline hydrochloride and morphocycline by using reverse turbidimetry]

The method of back turbidimetry was used for determination of the biological activity of the antibiotics, since high turbidity of the nutrient medium with Staph. aureus as the testculture prevented from direct measurements. Broth containing phosphate buffer, Staph. aureus and definite concentrations of the antibiotic was used as the reference solution. The experiments showed that the differences in the biological activities of tetracycline hydrochloride and morphocycline may be found with the method of back turbidimetry 6-8 hours after the microbe cultivation on media with the antibiotics.     

Biological properties of sherry yeasts in the presence of antimicrobial preparations

The wine yeasts Cheres were not sensitive to high concentration (500 gamma/ml) of benzylpenicillin, streptomycin, tetracycline, oxytetracycline, chlortetracycline, morphocycline, erythromycin, oleandomycin, monomycin, neomycin, kanamycin, polymyxin, ampicillin, oxacillin, methicillin, ceporin, ristomycin, levomycetin, furadonin and furazolidone. In concentrations of 50 to 500 gamma-ml oleadomycin, chlortetracycline, oxytetracycline, kanamycin and ristomycin inhibited synthesis of the Cheres yeast biomass. Benzylpenicillin, polymyxin, neomycin and ampicillin in concentrations of 50 to 100 gamma/ml had a stimulating effect on the yeast biomass synthesis.     

Intracellular distribution of tetracyclines in rat hepatocytes

Distribution of tetracyclines, such as oxytetracycline, morphocycline, tetracycline, doxicycline and methacycline in the liver cells of rats was studied. The ratio of the subcellular structures, i. e. nuclei, mitochondria and microsomes and the liquid phase containing the drugs in the dissolved state in the system studied was close to the natural ratio of the hepatocyte organoids and cytoplasm. Distribution of tetracyclines in the subcellular fractions was not uniform. The nuclei did not absorb the drugs. The role of microsomes in drug absorption was insignificant. The mitochondria bound the highest amounts of the drugs and defined the characteristics of their intracellular distribution. The amounts of the drugs in the active form remaining in the cytoplasm after their contact with organoids were low. At the same time there was observed a a definite activating effect of the cytoplasm components on the antibiotics contained in it.     

Effect of the physiological activity of Clostridium cells on their sensitivity to antibiotics]

Actively multiplicating cells of C1. perfringens proved to be more sensitive to 7-chlor-7-desoxylincomycin and rifampicin than the cells in the phase of the population dying. The bactericidal effect of the antibiotics on Clostridia vegetating at a temperature range within 37--4degrees was studied. Determination of the content of higher fatty acids in the cultivation medium with the method of gas chromatography showed that the metabolic processes in the bacterial cells went on at a temperature of 4degrees. Sensitivity of Clostridia to antibiotics at 20 and 4degrees lowered. However, all antibiotics inhibited the cell viability under such conditions. The inhibitors of the intracellular protein synthesis, i. e. rifampicin, 7-chlor-7-desoxylincomycin and morphocycline proved to be most active. The effect of beta-lactame antibiotics, i. e. cephaloridine and benzylpenicillin was reliable though lower.     

Rifampicin effectiveness in experimental anaerobic gas infection]

The inhibitory effect of rifampicin against most of 82 strains of pathogenic Clostridia was evident at a concentration of less than 0.1 gamma/ml. The bactericidal concentrations were close to the bacteriostatic ones with respect to 74 strains. The protective effect of rifampicin in mice with experimental anaerobic gaseous infaction caused by different species of pathogenic Clostridia was evident at doses of 0.5 mg/kg. In infections caused by associations of Clostridia and Staph. aureus resistant to other antibiotics, rifampicin was effective, while ampicillin had no protective effect. Rifampicin administered 24 to 96 hours before the infection prevented the specific process. A number of other antibiotics, such as ampicillin, cephaloridin, morphocycline and 7-chlor-7-desoxylincomycin had no such a capacity. The prolonged prophylactic effect of rifampicin was associated with maintenance of low antibiotic levels in the blood and muscle tissues which were higher than the minimum inhibitory concentrations. The effect of rifampicin against the background of a rapidly developing process was less pronounced and limited in time.

Better Prognosis in Newborns with Trisomy 13 Who Received Intensive Treatments: A Retrospective Study of 16 Patients

Intensive treatment for newborns with trisomy 13 is controversial because of their lethal prognosis. We report the better life prognosis of patients with trisomy 13 who received intensive treatment. At our hospital, we provided an intensive management to such patients including resuscitation and surgical procedures as required. Herein, we present the results of a retrospective study (1989-2010) of 16 trisomy 13 cases who received an intensive treatment. None was diagnosed to have trisomy 13 before birth; 9 were delivered by C-section and oxygen was administered to all patients during postpartum resuscitation. Mechanical ventilation was used in 9 patients after tracheal intubation and tracheotomy was performed in 2 patients when withdrawing of extubation was difficult. Regarding prognosis, 9 patients died, 3 were referred to another hospital, and 4 were discharged from the hospital. Four and 7 patients died within 7 and 30 days after birth, respectively. Nine patients survived for >1 month, 7 for >180 days, and 5 for >3 years. Median survival for 16 patients was 733 days. The patients who received intensive treatments survived longer compared to the previous data. This study provides useful information concerning genetic counseling, especially from an ethical point of view, before providing intensive management to newborns with trisomy 13.
