One of the most popular, cheap and widely used approaches in comparative cytogenetics - especially by botanists - is that concerning intrachromosomal and interchromosomal karyotype asymmetry. Currently, there is no clear indication of which method, among the many different ones reported in literature, is the most adequate to infer karyotype asymmetry(More)
In this study, the cytogenetic effects of black tea and green tea were determined in cultured peripheral blood lymphocytes. Results showed that black tea and green tea induced the mitotic and replication indexes and decreased micronuclei. But these data were not statistically significant for green tea. The effects of black tea on the micronucleus formation(More)
Gas metal arc welding is a widely used method in a lot of industrial areas as it is cheap and produces high quality results. In the present study, peripheral blood lymphocytes of 23 welders and 25 non-exposed subjects were monitored for cytotoxicity. Information regarding the subjects’ ages, smoking habits, alcohol consumption, duration of exposure, and(More)
Karyotypic characters, mitotic metaphase chromosomes, monoploid idiograms and karyograms of Minuartia anatolica (Boiss.) Woronow var. phrygia (Bornm.) McNeill, Minuartia anatolica (Boiss.) Woronow var. scleranthoides (Boiss. & Noe) McNeill, Minuartia corymbulosa (Boiss. & Balansa) McNeill var. gypsophilloides McNeill and Minuartia aksoyi M.Koç & Hamzaoğlu(More)
In the present research, the effects of gamma radiation on mitotic index have been investigated. Seeds of Hordeum vulgare L. were treated with different doses of gamma ray (50, 100, 150, 200, 250, 300 Gy). MI (mitotic index) at embryonic root tip of barley seedling has been decreased with increasing doses of gamma radiation. The inhibitory effects of gamma(More)
The synthetic dyes over fifty are used in many areas including the food industry around the world. Sunset Yellow FCF and Brilliant Blue FCF are used as colorant food additives in many food products. The present study investigated the genotoxic and cytotoxic effects of Sunset Yellow and Brilliant Blue. Genotoxic and cytotoxic activities of the food additives(More)
Organophosphorus insecticides are used worldwide in the control of agricultural, household and veterinary pests. Dichlorvos (2,2-dichlorovinyl dimethyl phosphate) is a commonly used organophosphorus insecticide. In this study, in order to elucidate the toxic nuclear effects of dichlorvos, freshly isolated human peripheral blood lymphocytes were incubated(More)
Hypericum species, growing wild in Anatolia, widely used in traditional medicine in Turkey. In order to determine the genotoxic effect of Hypericum heterophyllum, human lymphocytes were incubated with the aqueous extracts. The increasing extract concentrations of Hypericum heterophyllum induced micronucleus. The rise of micronucleus shows that Hypericum(More)
The in vitro cytotoxic potentials of Furo[3,2-c]pyran-4-one derivatives in human lymphocytes were investigated. Blood samples were obtained from six healthy donors, non-smoking volunteers, which were incubated and exposed to increasing concentrations (0.05, 0.1, 0.5, 1 and 2 mg/mL) of Furo[3,2-c]pyran-4-one derivatives which are methyl(More)
Helichrysum Mill. (Asteraceae) species have been used in folk medicine for thousands of years in the world. The in vitro cytogenetic effects in human lymphocytes of nine Helichrysum taxa used in Turkey folk medicine were investigated. Blood samples were obtained from healthy donors, non-smoking volunteers, which were incubated and exposed to increasing(More)
