Metal ions were evaluated as potential antimicrobial agents suitable for local delivery in the oral cavity for the treatment of periodontitis. Silver nitrate, copper chloride, and zinc chloride were tested for antimicrobial activity in in vitro killing assays conducted in phosphate buffered saline with a series of oral bacteria including gram-negative periodontal pathogens and gram-positive str...

STUDY OBJECTIVE To determine whether the administration of antiinflammatory drugs interferes with experimental pleurodesis induced by silver nitrate or talc. STUDY DESIGN Two groups of 30 white New Zealand rabbits were scheduled to receive an intrapleural injection of 0.5% silver nitrate or 400 mg/kg of talc. Each group was further classified into three subgroups (10 animals each), which rece...

The lecithins of rat liver are resolved into three fractions by chromatography on a thin layer of silica gel impregnated with silver nitrate. Each of these fractions is placed in a small column containing a cation-exchange resin, and the lecithins are eluted free from silver nitrate. Recoveries average 96%.

The physical and chemical methods employed in production of silver nanoparticles are expensive and the reagents used are harmful. This project deals with the production of silver nanoparticles using biological methods. Silver nitrate is reduced by biological extracts. Thus, the production is mainly dependent on the reducing ability of the plant used. Lemon extract has been used for the synthesi...

The present paper shows through conventional light microscopy, silver nitrate impregnation and Transmission Electron Microscopy, the changes in nuclear activity that occurs in the ovary cells during vitellogenesis of Apis mellifera (Linnaeus, 1758). The material impregnated by silver nitrate was detected in nurse cells, oocyte germinal vesicle and follicular cells, whose amounts are greater in ...

background and objectives: pseudomonas aeruginosa is an opportunistic pathogen that can produce biofilm. biofilm is a complex, three dimensional structure in which microorganisms are attached to a surface and embedded in a matrix made of extracellular polymers. due to high resistance to antimicrobial agents, biofilms create difficulties in various situations in healthcare. in this study, antibi...

Silver nanoparticles (AgNPs) were synthesized using Bacillus cereus strains. Earlier, we had synthesized monodispersive crystalline silver nanoparticles using B. cereus PGN1 and ATCC14579 strains. These strains have showed high level of resistance to silver nitrate (1 mM) but their global transcriptomic response has not been studied earlier. In this study, we investigated the cellular and metab...

Background: One of the most serious late complications, after evacuation of liver hydatid cyst and instillation of scolicidal agents is sclerosing cholangitis, most probably caused by the type of scolicidal agents instilled. Objective:  To determine the incidence of sclerosing cholangitis after intra-biliary tract infusion of 5% saline and 0.5% silver nitrate. Methods: 5% hypertonic saline and ...

In this study, topical effectiveness of silver nitrate pencil on 33 dairy cows with ringworm (Fig. 1) was evaluated. The diameter, number and localized areas of lesions were recorded in each cattle. Later lesions were first cleansed with 70 % ethyl alcohol. Skin scraping and hair specimens were collected of the margin of the lesion using a sterile scalpel blade into sterile petri dish. Lesions ...

silver-polyaniline (ag-pani) nanocomposites were prepared by in-situ oxidative polymerization of aniline monomer in sodium bis(2-ethylhexyl) sulfosuccinate (aot) solution as an emulsifier. the synthesis of silver-polyaniline nanocomposites was investigated as a function of several parameters such as aniline concentration, concentration of emulsifier (aot), concentration of oxidation agent and c...
