Silver Nitrate Solution (silver + nitrate_solution)
Selected AbstractsEfficacy of 10% silver nitrate solution in the treatment of common warts: a placebo-controlled, randomized, clinical trialINTERNATIONAL JOURNAL OF DERMATOLOGY, Issue 2 2007Sedigheh Ebrahimi MD Background, Warts are a common skin lesion, especially in children and young adults, caused by human papillomaviruses. So far, there is no definitive therapy for warts and the treatment is modified regularly to obtain the best result with the least discomfort to the patient. The aim of this placebo-controlled clinical trial was to evaluate the clinical efficacy, tolerability, and safety of 10% silver nitrate solution for the treatment of common warts. Methods, Sixty individuals attending pediatrics and dermatology clinics and health centers in Yasuj, south-west of Iran, were recruited. The patients were divided into two groups: 30 patients received 10% silver nitrate solution (case group) and 30 control patients received black ink (placebo group). Silver nitrate solution was used every other day for 3 weeks. After 3 weeks, the patients were evaluated for healing, and treatment was continued for another 3 weeks if the lesions were still present. Results, Complete regression of lesions was achieved in 19 of the 30 (63.33%) case patients. No significant side-effect was noted in the treated patients apart from temporary brownish discoloration of the skin which resolved 1 week after treatment. Conclusion, This study demonstrated that 10% silver nitrate solution can be used effectively for the treatment of warts with no serious complications.

A series of DBD fabric treatments was performed in order to determine the most suitable experimental conditions for the fabric surface activation. The capillarity, silver ion uptake, and copper number were used to assess the surface changes on the fabrics. An effective process has been developed to obtain antimicrobial silver-loaded Co/PES fabrics. The antimicrobial activity of the silver-loaded fabrics against different pathogens was evaluated in vitro. The quantity of bonded silver ions is enough to develop desirable antimicrobial activity in the Co/PES fabrics.

The morphology and diameter of PAN/TiO2 composite nanofibers could be controlled by varying the initial contents of TiO2 in the spinning solution. From TEM images and UV-Vis spectra, it has been confirmed that monodisperse silver nanoparticles with a diameter of ,2 nm were deposited selectively upon the titania of the as prepared composite nanofibers. The amount of Ag nanoparticles embedded on composite nanofibers was greatly influenced by the amount of TiO2 in composite nanofibers, reflecting the role of titania as the inorganic stabilizer and photocatalyst.
