| pubmed-article:3692108 | pubmed:abstractText | There was analysed the behaviour of the pulmonary tissue in white Wistar female rats exposed to a single effect of electroenergetic ashes from a few Polish power stations, hasting plants and electrohasting plants. The animals received a single 0.6 ml dose of the ashes in suspension of physiologic fluid intratracheally; 3 and 6 months after the experiment, the animals were decapitated and material for examinations was collected. Grains of used ashes were then assessed under the scanning electron microscope. Segments were stained with hematoxyline and cosine and by Masson's method. All the ashes caused inflammatory infiltrations, granulomas containing grains of the examined ash, fibrosis, thickening of interalveolar septa, atelectasis, and emphysema. The experiment resulted in a disturbance of biological balance of pulmonary connective tissue (stroma) due to the action of the ashes. | lld:pubmed |
