Different copper concentrations, as well as different exposure times, were applied to investigate both cytogenetical and ultrastructural alterations in garlic (Allium sativum L.) meristem cells. Results showed that the mitotic index decreased progressively when either copper concentration or exposure time increased. C-mitosis, anaphase bridges, chromosome stickiness and broken nuclei were obser...

Ramsar, a northern coastal city of Iran, overlooking the Caspian Sea, has some high level natural radiation areas (HLNRAs) as well as over 50 hot springs with low and high radium contents used as spas by the public and vacationers. The average whole body dose received by population in these areas is about 5 times higher than the normal background radiation level. Studies on the long-term effect...

WATANABE, M., TAKAYAMA, Y., KOIKE, M. and YAMAMOTO, M. In Vivo Clastogenicity of Lead Chromate in Mice. Tohoku J. exp. Med., 1985, 146 (3), 373-374 Cytogenetical effects of lead chromate were evaluated in vivo. When 0.5, 1, 2 and 4 g/kg body weight of lead chromate suspensions in 0.5% gum arabic were administered i.p. to C57BL/6N male mice twice, the frequencies of micronucleated polychromatic ...

Myelodysplastic syndromes (MDS) are characterized by peripheral cytopenias in combination with a hyperplastic bone marrow. During the last 15 years, important progress has been made in the understanding of the biology and prognosis of myelodysplastic syndromes. The classification according to the World Health Organization (WHO) includes mainly morphological criteria and is supplemented by the I...

The term "dauermodifications' was coined by Jollos in 1913 and he described it as a change induced externally by an experimental means at a definite moment (Jollos 1921). Sonneborn (1950) regarded dauermodifications as the traits induced by environmental conditions, manifesting temporary cytoplasmic inheritance. Hence, after some period, under the original conditions, the induced traits disappe...
