background: intoxication with aluminum phosphide has been prevalent in iran recently. lab confirmation of the poisoning is needed in clinical and post-mortem settings. present study was conducted to determine efficiency and validity of silver nitrate test for detection of aluminum phosphide in samples. methods: information about dead patients with history of aluminum phosphide poisoning referre...
or 4, must be added to the urinometer reading to bring it to the true specific gravity. The estimation of chlorides can be done volumetrically with standard silver nitrate solution and potassium chromate as indicator; this method is sufficiently accurate for the purpose. The standard silver nitrate solution is made by dissolving 29.235 grammes of pure and dry crystals of silver nitrate in a lit...
OBJECTIVE The aim of this prospective multicenter randomized controlled trial was to compare the efficacy of silver nitrate cauterization against that of topical steroid ointment in the treatment of neonatal umbilical granuloma. METHODS An open-label, non-inferiority randomized controlled trial was conducted from January 2013 to January 2016. The primary endpoint for the silver nitrate cauter...
The in vitro activity of the silver nitrate was assessed in comparison with that of natamycin against 128 corneal Fusarium isolates and 90 corneal Aspergillus isolates. MIC(90)s of silver nitrate were 2 microg/ml for Fusarium spp. and 1 microg/ml for Aspergillus spp. MIC(90)s of natamycin were 8 microg/ml for Fusarium spp. and 32 microg/ml for Aspergillus spp. Silver nitrate exhibited potent an...
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...
Effects of different concentrations of silver nanoparticles and silver nitrate on some hematological indices of Zayanderud Chub (Petroleuciscus esfahani) were investigated. One hundred individuals of the fish (average weight 26.4 ± 1.3 g) were divided into 5 experimental groups, exposed to 1 or 25 µg/L of silver nano or silver nitrate or unpolluted water as control for 10 days. At the end, prim...
This report describes a new modification of the Gallyas method for staining myelin in fixed brain tissue and compares results of multiple myelin-visualizing techniques in normal common marmoset (Callithrix jacchus), normal macaque monkey (Macaca mulatta), and a human with multiple sclerosis. The new modification involves immersion in 10% formalin following impregnation in ammoniacal silver nitr...
Spittlebugs annually infest pastures and cause severe damage, representing a serious problem for the tropical American beef cattle industry. Spittlebugs are an important biotic constraint to forage production and there is a lack of cytogenetic data for this group of insects. For these reasons, we conducted this work, in which the spermatogenesis and nucleolar behavior of Deois flavopicta, Mahan...
We evaluated the use of silver nitrate drops and tetracycline ointment for the prophylaxis of ophthalmia neonatorum in a controlled trial involving 2732 newborns in Nairobi, Kenya. The overall rates of prevalence of intrapartum maternal gonococcal and chlamydial infection were 6.4 and 8.9 percent, respectively. After prophylaxis with silver nitrate, the incidence rates of gonococcal, chlamydial...
Epistaxis from the anterior septum is frequently treated with a topical application of silver nitrate, which cauterizes the bleeding vessel. However, this treatment causes a septal perforation in a small percentage of patients. We report our study of the histologic effect of topical silver nitrate on samples of septal tissue obtained from 11 patients. We found that 30 seconds of exposure allowe...
