Genotoxicity of textile dye C.I. Disperse Blue 291 in mouse bone marrow
(2019-01-01)
Color Index (C.I.) Disperse Blue 291 (DB291) is an azo dye used by the textile industry. After yarn dyeing, wastewater containing the dye, released into the aquatic environment, may pollute drinking water sources. We ...
Paracoccidioidomycosis: No genetic damage in human peripheral blood cells of patients assessed by single-cell gel (comet) assay
(2007-07-01)
Paracoccidioidomycosis is a systemic fungal infection caused by Paracoccidioides brasiliensis. As infectious diseases can cause DNA damage, the authors aimed at analyzing DNA breakage in peripheral blood cells of patients ...
Lack of DNA damage induced by fluoride on mouse lymphoma and human fibroblast cells by single cell gel (comet) assay
(2006-12-01)
Fluoride has widely been used in Dentistry because it is a specific and effective caries prophylactic agent. However, excess fluoride may represent a hazard to human health, especially by causing injury on genetic apparatus. ...
Chlorination treatment of aqueous samples reduces, but does not eliminate, the mutagenic effect of the azo dyes Disperse Red 1, Disperse Red 13 and Disperse Orange 1
(Elsevier B.V., 2010-12-21)
The treatment of textile effluents by the conventional method based on activated sludge followed by a chlorination step is not usually an effective method to remove azo dyes, and can generate products more mutagenic than ...
Protective action of propolis on the rat colon carcinogenesis
(Wiley-Blackwell, 2002-01-01)
Propolis is a honeybee product with several biological and therapeutical properties. Its effect on the process of colon carcinogenesis and DNA damage were evaluated in the male Wistar rats using the aberrant crypt foci ...
Sex determination of murine and bovine embryos using cytotoxicity and immunofluorescence assays
(1993-06-01)
Murine and bovine embryos were sexed by using polyclonal and monoclonal anti-H-Y antibodies in cytotoxic and immunofluorescence assays. The specificity of 3 different sources of antibodies are compared. Sexing was accomplished ...
Investigation of the Genotoxic Potential of the Waters of a River Receiving Tannery Effluents by Means of the in vitro Comet Assay
(2003-12-01)
The comet assay has been described as an efficient tool for the detection of changes in the DNA molecule of cells exposed to contaminating agents in vivo and in vitro. The possible environmental contamination due to the ...
Evaluation of the genotoxic potential due to the action of an effluent contaminated with chromium, by the comet assay in CHO-K1 cultures
(2005-12-01)
The comet assay technique has been considered to be more efficient in the biomonitoring of aquatic environments that the micronucleus and sister chromatid exchange techniques. The comet assay has been used to determine ...
A novel and rapid microbiological assay for ciprofloxacin hydrochloride
(2013)
The present work reports a simple, fast and sensitive microbiological assay applying the turbidimetric method for the determination of ciprofloxacin hydrochloride (CIPRO HCl) in ophthalmic solutions. The validation method ...
Chlorhexidine induces DNA damage in rat peripheral leukocytes and oral mucosal cells
(Blackwell Munksgaard, 2004-10-01)
Objective: Chlorhexidine digluconate is widely used in dental practice for decreasing plaque control, controlling gingivitis and disinfecting root canals. However, the undesirable effects of chlorhexidine digluconate ...
