| Popis: | The long-term consequences of the use of dioxine-containing ecotoxic agents in the USA in 1961-1972 are ecologically and genetically characterized. There were increases in the incidence of pathological reproductive events in the contaminated region. It is concluded that there will be higher probability of abnormalities in the families of individuals born at war or just thereof. An association of impaired reproduction with functional disorders and women's poorer health, with higher incidence of somatic and gynecological diseases (chronic ones in particular) is shown. Cytogenetic changes in the lymphocytes were found in individuals from exposure risk groups. The contribution of chromosomal alterations observed in the contaminated area to immunodeficiency is appreciated. The systemic pattern of the action of biologically active properties of dioxine was demonstrated from the morphofunctional changes of different cell types. Cluster analysis revealed associations of cytogenetic parameters with the integrated index of health status in individuals from different contaminated areas. The ecological and genetic consequences may be regarded as part of homeostatic changes at many levels, as suggested by a correlation between the genetic instability and the changes occurring in other tissues, organs, and systems. |
