Suppression of mutagens-induced SOS response by phytoncide solution using Salmonella typhimurium TA1535/pSK1002 umu test.
Four types of phytoncide solution (A-Type, AB-Type, D-Type and G-Type) were evaluated as antimutagenic agents with suppressive effects on the SOS-inducing activity of the mutagen 2-(2-furyl)-3-(5-nitro-2-furyl) acrylamide (furylfuramide) using Salmonella typhimurium TA1535/pSK1002 umu test. The A-Type, AB-Type, D-Type and G-Type of phytoncide solution suppressed the SOS-inducing activity on fur...
متن کاملA new Salmonella typhimurium NM5004 strain expressing rat glutathione S-transferase 5-5: use in detection of genotoxicity of dihaloalkanes using an SOS/umu test system.
The Escherichia coli mu operon was subcloned into a pKK233-2 vector containing rat glutathione S-transferase (GST) 5-5 cDNA and the plasmid thus obtained was introduced into Salmonella typhimurium TA1535. The newly developed strain S.typhimurium NM5004, was found to have 52-fold greater GST activity than the original umu strain S.typhimurium TA1535/pSK1002. We compared sensitivities of these tw...

متن کاملChemiluminescence Properties of Peroxyoxalate System in Organic Solvents
Peroxyoxalate system includes an oxalate ester, peroxide and a fluorescer, The energy resulted from the reaction of oxalate ester and peroxide is transferred to fluorescer and cause it to fluorsc. The effect of reactants chemical structure, their concentration, solvent media (polarity and viscosity) and the temperature, on the intensity of the illuminated light with respect to time have bee...
متن کاملThe Effects of Organic Solvents on the Physicochemical Properties of Human Serum Albumin Nanoparticles
Background: Recently, applications of albumin nanoparticles as drug delivery carriers have increased. Most toxicology studies have shown that surface chemistry and size of nanoparticles play an important role in biocompatibility and toxicity. Objective: The effect of desolvating agents with different chemical properties on the size of synthesized HSA NPs was investigated. Materials and Method...
