Background: Radioprotective capability of histamine H2 receptor antagonists have been shown in several in vivo studies mainly using animal models. However, to verify the effectiveness of these agents in clinical applications, studies should be performed on human cells. In the present study radioprotective properties of these agents was examined in vitro on human lymphocytes using metaphase anal...
The rising global demand for palm oil and its associated products has led to increased numbers of palm oil refineries with its attendant effluent discharge. Many researches have confirmed the ecological disruptive potentiality of Palm Oil Mill Effluent (POME), still further attention has to be directed at POME’s potential genotoxicity. The present study has made physico-chemical and genotoxicit...
Introduction: Exposure to ionizing radiation as a result of diagnostic, treatment and occupational reasons, has created a remarkable range of cytogenetic damage in the DNA, as the first and main goal of ionizing radiation. The aim of this study is to assess the chromosomal damage in medical radiotherapy workers and its association with effective parameters such as age, sex, duration of employme...
the frequency of chromosomal aberrations was studied in the peripheral blood lymphocytes of 65 radiology technologists crt) working at hospitals chronically exposed to x-rays. although film dosimetry did not show the maximal annual permitted dose in any of the examined subjects, cytogenetic analysis detected fairly high levels of chromosomal aberrations in r t compared to unexposed controls. th...
Background Cytogenetic study of reproductive wastage is an important aspect in determining the genetic background of early embryogenesis. Approximately 15 to 20% of all pregnancies in humans are terminated as recurrent spontaneous abortions (RSAs). The aim of this study was to detect chromosome abnormalities in couples with RSAs and to compare our results with those reported previously. Materia...
ABSTRACT The increasing use of medical herbs and their products and the proof of mutagenicity and oncogenicity of some of their components justify more researches about these effects of herb products. The objective of the present study is to explore the cytogenetic toxicity of a product currently available in Iranian drug market called Antimigrin. One of the methods used for the study of mutag...
The present study has investigated the cytoprotective effects of chlorophyllin in tobacco induced chromosomal aberrations in bone marrow of rats. Chromosomal aberrations per cell and percent aberrant cells were observed to calculate genotoxic action of tobacco. Oral treatment with different doses of chln was able to reduce chromosomal aberrations significantly at the pre-treatment level and con...
