Domestic sewage treated in municipal sewage treatment plants is only analyzed for its physicochemical properties correction prior to its discharge but as domestic sewage is proved to contain genotoxicity also, it is suggested that the discharge should also be checked for genotoxicity. Many microbial genotoxicity tests are employed for genotoxicity testing. These tests are simple, quick and empl...

Comparative mutagenic and genotoxic effects of three antimalarial drugs, chloroquine, primaquine and amodiaquine, were assessed in the Ames mutagenicity assay (in strains TA97a, TA100, TA102 and TA104) and in vivo sister chromatid exchange (SCE) and chromosome aberration (CA) assays in bone marrow cells of mice. These are the most commonly used antimalarial drugs available at present throughout...

Purpose: To evaluate the genotoxicity of CSE1034, a novel antibiotic adjuvant entity, using bacterial reverse mutation assay (Ames test) and in vitro chromosomal aberration test. Methods: Reverse mutation test was carried out using four strains of Salmonella typhimurium (TA 98, TA100, TA1535 and TA1537) and one strain of E. coli [WP2 (uvrA)], while chromosomal aberration test was done with cult...

waterpipe smoking has become a global youth trend especially in the middle east countries and iran . the aim of this study was to determine the mutagenic effects of three most popular flavored tobaccos by four different salmonella typhimurium strains and compare the possible mutagenic effects of the test samples. ames mutagenicity assessment was conducted according to the oecd guideline using t...

1,3-Butadiene and two major genotoxic metabolites 3,4-epoxybutene (EB) and 1,2:3,4-diepoxybutane (DEB) were used as model compounds to determine if genetic toxicity findings in animal and human cells can aid in extrapolating animal toxicity data to man. Sister chromatid exchange (SCE) and micronucleus induction results indicated 1,3-butadiene was genotoxic in the bone marrow of the mouse but no...

The genotoxic and antigenotoxic effects of Aloe vera leaf extract (AV) were investigated using the chromosome aberrations (CAs) test for the bone marrow cells of rats, sister chromatid exchanges (SCEs) and micronucleus (MN) and CAs tests for human lymphocytes, and the Ames Salmonella/microsome test system. In the bone marrow cells of rats, AV extract significantly induced structural and total C...

It is still unclear whether the exposure to electromagnetic fields (EMFs) generated by mobile phone radiation is directly linked to cancer. We examined the biological effects of an EMF at 835 MHz, the most widely used communication frequency band in Korean CDMA mobile phone networks, on bacterial reverse mutation (Ames assay) and DNA stability (in vitro DNA degradation). In the Ames assay, test...

This paper surveys recent, as yet unpublished, statistical studies arising from research in genetic toxicology within the U.S. National Toxicology Program (NTP). These studies all involve analyses of data from Ames Salmonella/microsome mutagenicity tests, but the statistical methodologies are broadly applicable. Three issues are addressed: First, what is a tenable sampling model for Ames test d...
