Mutagenicity studies of vinyl chloride.
Mutagenicity studies in both man and in test organisms clearly demonstrate positive mutagenic activity of vinyl chloride. In terms of the mutagenicity studies using a variety of in vitro procedures covering both eukaryotes and prokaryotes, positive effects were found. Cytogenetic in vivo studies in animals and in humans indicate not only somatic mutations, but also germinal effects with this ch...
متن کاملQuantum-chemical studies on mutagenicity of aromatic and heteroaromatic amines.
Arylamines are well-known as widespread industrial and environmental mutagens and carcinogens. Their bioactivity stems from enzymatic metabolic activation to reactive and highly electrophilic intermediates. In this work, computational investigations related to the biological activity of these compounds have been reviewed, especially focusing on studies reporting results from quantum-mechanical ...
متن کاملStudies in mice on the mutagenicity of two contraceptive drugs.
An experiment is described which tests for visible and invisible mutants in mice treated with four different doses each of the contraceptives Gynanovlar and Lyndiol. The results show that there is no reason to suppose that either substance has an appreciable mutagenic effect, expressed as an increase of antenatal and postnatal lethals or visibles. The substrain CBA/CagCam, used throughout, has ...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
Mutagenicity and anti-mutagenicity of selected spices.
Using Salmonella typhimurium strains TA 100 and TA 1535, the mutagenicity and anti-mutagenicity of extracts of several spices were checked. Spices like pepper, pippali, ginger and mustard increased the number of revertants indicating their mutagenic potential. Garlic extract on the other hand was found to inhibit the mutagenicity produced by direct acting mutagens such as N-methyl N'-nitro-N-ni...
