Background and Objectives: Clostridium difficile is a gram-positive obligate anaerobic bacillus. Accurate and rapid diagnosis of this bacterium as well as assessment of its drug resistance pattern are one of the important issues in controlling infections caused by C. difficile. The purpose of the present study was to detect toxicogenic C. difficile and to evaluate drug resistance pattern of these...
Abstract Background and purpose: Rice is the staple food in Iran particularly in the northern provinces of Gilan and Mazandaran. It is, however, prone to mycoflora and mycotoxin production. This study was conducted to determine the contaminant mycoflora of rice grains in Mazandaran province, in order to use this information to consider possible mycotoxin occurrence in this area. Materials a...
BACKGROUND Scorpions stings are a health problem in many parts of the world. Mesobuthus eupeus (Buthidae) is the most prevalent species in the Middle East and Central Asia. Definition of toxicogenic and immunogenic characteristics of the venom is necessary to produce antidote. In this study, the noted properties of M. eupeus venom were evaluated. METHODS Venom was obtained by milking M. eupeu...
Ifosfamide is a well known prodrug for cancer treatment with cytochrome P450 metabolism. It is associated with both antitumor activity and toxicities. Isophosphoramide mustard is the bisalkylating active metabolite, and acrolein is a urotoxic side product. Because acrolein toxicity is limited by coadministration of sodium mercaptoethanesulfonate, the incidence of urotoxicity has been lowered. C...
backgrounds and objectives: photocatalyst titanium dioxide nanoparticles can oxidize organic and inorganic compounds of microorganisms in aqueous solutions after exposure to uv light. in the present study, the inhibitory effect of titanium dioxide and its photocatalyst type on aspergillus flavus , escherichia coli and staphylococcus aureus is investigated. materials and methods: toxicogenic s...
in this study,the effect of ozonated water(0.2, 0.5, and 1 ppm) with different exposure times (5,10, and 15 min) for control of staphylococcus aureus , escherichia coli and total counts in poultry carcass, on chiller water in slaughter house were investigated. for this purpose, control samples passed chiller water(without ozone) for (5,10, and 15 min) .other examples also treated (5, 10 , and 1...
Objective(s): Scorpion venom has toxic effects on mammals, insects and crustaceans. Toxicogenic peptides are major contributors to the scorpion venom, which make it toxic. The Hemiscorpius lepturus (H. lepturus) is one of the most common scorpion bites agent, and responsible for 95% of scorpion bite deaths cases in Iran.Materials and Methods:</strong...
OBJECTIVES Low exposures to volatile aromatic hydrocarbons and cytogenetic effects in peripheral white blood cells were determined in 25 healthy workers employed in different areas of a styrene production plant in the former German Democratic Republic. The results were compared with 25 healthy unexposed controls (matched for age and sex) employed in the same company. METHODS The concentration...
