[The efficacy of Ligenten gel in the prevention and treatment of infectious-inflammatory diseases of the urogenital organs].

A new therapeutic in the form of a gel named ligenten was studied. The gel active components are lidocain, gentamicin and ethonium. Ligenten was shown to have a marked local anesthetic action when administered transurethrally. As a prophylactic agent the gel was highly active against the majority of the causative agents of renal infections due to cystoscopy, catheterization and bougienage of the urethra. Ligenten provided a sufficient anesthetic effect in transurethral operations but did not prevent superinfection due to the hospital strains. Marked antiinflammatory and reparative actions of the gel especially in the treatment of ulcerous cystitis were observed.

[Gentacycol--a delayed-action form of gentamicin in the treatment of suppurative infection].

Efficacy of gentacycol was studied in the treatment of various purulent infections. It was used in therapy of hematogenic and traumatic osteomyelitis, wound infections, soft tissue abscesses, purulent diffuse peritonitis as a complication of comissural ileus or appendectomy, pyothorax, destructive pneumonia and mediastinitis. Gentacycol ++ was also used for the prophylaxis in cholecystectomy, herniotomy and other conditions. The favourable results were stated in 93 per cent of the cases.

[Erythromycin pharmacokinetics in children after rectal and oral administration].

Pharmacokinetics of erythromycin base was studied clinically in children not older than 14 years treated with new children dosage forms of the antibiotic i. e. 0.1 and 0.25 g enteric coated tablets and 0.06 and 0.125 g suppositories. It was noted that the new dosage forms were characterized by higher availability which was 2.5-3 times higher than that after using the erythromycin base tablets without the coating. Systematic increasing of erythromycin availability after the use of the rectal suppositories was observed with increasing of the children age. Absolute absorption in newborns, sucklings and children over 1 year amounted to 28, 36 and 54 per cent respectively.

[Tolerance of gentacycol--a local dosage form of gentamicin based on collagen--animal experiments].

Gentacycol is a local dosage form of gentamicin based on collagen for implantation to wounds in treatment of patients with infections of soft tissues and prevention of contamination of open injuries of the bones and soft tissues. General toxic and organotropic properties of gentacycol were studied on animals with subcutaneous implantation of the dosage form in doses equivalent to the therapeutic dose for man and exceeding it 2-fold. The study showed that the dosage form had no unfavourable side effects on the animal general state, hearing, the functional state of the liver and kidneys and the peripheral blood. In the doses tested gentacycol did not influence the indices of the cardiovascular system and neuromuscular conduction. Morphological examination of the skin and hypodermic tissues in the implantation site revealed no damaging action of the dosage form on the surrounding tissues.

[Experimental study of a novel formulation for local application based on gentamicin, erythromycin and protease C].

A novel formulation for local application based on an enzyme of microbial origin, C protease, and two antibiotics, gentamicin and erythromycin, was studied on various experimental models in rats with respect to its effect on necrotic tissues and recovery of the skin and hypodermic tissue defects due to wounds. It was found that even within the first days of the application the formulation induced lysis of the primary crust, lowered exudation and promoted debridement, reduced the wound size and completely closed it. By its effect the formulation was similar to iruxol. In chronic experiments on animals with long-term application of the formulation to the skin and wound surfaces it showed no unfavourable general toxic or organotropic properties. The local irritating action was insignificant.

[Intramolecular hydrogen bonds and conformation of the lincomycin molecule in organic solvents].

IR spectra (1600-1800 and 3000-3650 cm-1) of lincomycin base solutions in inert (CCl4 and C2Cl4), proton acceptor (dioxane, dimethylsulfoxide and triethyl amine) and proton donor (CHCl3, CD3OD and D2O) solvents were studied. Analysis of the concentration and temperature changes in the spectra revealed that association in lincomycin in the inert solvents was due to intramolecular hydrogen linkage involving amide and hydroxyl groups. Disintegration of the associates after the solution dilution and temperature rise was accompanied by formation of intramolecular bonds stabilizing the stable conformation structure of the lincomycin molecule. The following hydrogen linkage in the conformation was realized: NH...N (band v NH...N at 3340 cm-1), OH...O involving the hydroxyl at C-7 and O atoms in the D-galactose ring (band v OH...O at 3548 cm-1), a chain of the hydrogen bonds OH...OH...OH in the lincomycin carbohydrate moiety (band v OH...O at 3593 cm-1 and v OH of the end hydroxyl group at 3625 cm-1). Bonds NH and C-O of the amide group were located in transconformation. Group C-O did not participate in the intramolecular hydrogen linkage.

[Rheological research in creating antibiotic hydrogels].

Experimental design was used in studying the effect of certain qualitative factors on rheological properties of antibiotic hydrogels. It was shown that water solubility of antibiotics and the procedure of their addition to gel bases were important in developing hydrogels. Scanning electron microscopy was used in comparative analysis of antibiotic hydrogels.

[Experimental study of lincomycin ointment and gel].

The pharmacokinetics and safety of the lincomycin ointment and gel were studied. It was shown that diffusion of lincomycin through the skin was satisfactory. Investigation of their general toxicity and organotropic properties revealed neither irritating effect nor changes in the internal organs associated with the toxic effect of the drugs. On the basis of the data on the stability of the lincomycin ointment and gel obtained on their storage the lincomycin ointment was recommended for industrial production.

[Experimental study of a gentamycin ointment].

Technology of 0.1 per cent gentamicin ointment production was developed. The ointment base consisted of vaseline and parafin (95:5). Pharmacokinetics and innocuousness of the gentamicin ointment were studied. It was shown that the ointment provided gentamicin diffusion through the skin utegument during a long period of time. Histological studies showed no local irritating effect of the ointment on the skin in its local use.

[Pharmacokinetic characteristics and the chemotherapeutic effectiveness of a 2% ditetracycline-erythromycin eye ointment].

The study of the antibacterial activity of ditetracycline combination with erythromycin (ratio 1 : 1) showed that the effect of the antibiotics increased with respect to most of Staphylococcus and Coli bacteria. The chemotherapeutic effect of the ointment in treatment of experimental staphylococcal conjunctivitis of rabbits was also studied. The clinical signs of the disease disappeared earlier than in the experiments with the use of ditetracycline and erythromycin ointments alone. The experiments with the rabbits revealed a prolonged effect of the ointment: ditetracycline and erythromycin in therapeutic concentrations were detected in the conjunctiva and cornea after a single application for 24--48 and 8 hours respectively.

[Protegentin--a combined preparation for the local treatment of suppurative infection].

Protegentin is a formulation in the form of an ointment for local application. Its high efficacy was demonstrated in the treatment of wounds in the 1st phase of the process, extended decubitus, trophic ulcers, wounds of various genesis not healing for prolonged periods, urogenital infections, abscesses, maxillofacial phlegmon and abscessing parodontosis. The ointment showed good draining, proteolytic and bactericidal effects. The tolerance was good. The positive results were observed in 97 per cent of the cases.
