What's new in intraperitoneal test on Kevlar (asbestos substitute)?
The intraperitoneal test is a suitable experimental method for studying the different patterns of morphological reaction to foreign body substances of various kinds and concentrations as well as their transport within and elimination from the organism…

Mesothelial proliferation due to asbestos and man-made fibres. Experimental studies on rat omentum
…in rats has proven to be an appropriate method controlling fibrogenicity and carcinogenicity of asbestos fibres and other fibrous dusts. We analyzed the reaction patterns of mesothelial cover layer to different natural mineral fibres (crocidolite, chrysotile…

Black spots of the parietal pleura: morphology and formal pathogenesis
…in close correlation to lymphatic channels and blood vessels. Their formal pathogenesis is characterized by a mild fibrosis and an inflammatory reaction to the incorporated foreign particles. The proliferation of connective tissue may result in the…

Reactive lesions of the pleura. Immunohistochemical characterization
…The antibodies Leu M1, HEA 125 and BMA 130c (against CEA) showed no reaction in subserosal and mesothelial cells. With the antibody HMFG 2, however, a weak reaction could be observed. A distinction between reactive and…

E-cadherin, E-selectin and vascular cell adhesion molecule: immunohistochemical markers for differentiation between mesothelioma and metastatic pulmonary adenocarcinoma?
…staining patterns for VCAM and E-selectin, there were significant differences in the expression of E-cadherin: while nearly all adenocarcinomas stained positively, there was almost no staining reaction of the mesotheliomas. Therefore, E-cadherin -- in…

Exposure to carbon black: a cancer risk?
…tissues. It is therefore quite understandable that many researchers propose to interpret the changes observed in rat lung tissues after inhalation of carbon black as rat-specific reaction mechanisms that cannot be applied to human tissues…

Scanning electron microscopical investigations of broncho-alveolar casts after intratracheal asbestos fibre instillation
…the pleural space could not be explained satisfactorily. Histomorphological examinations showed that intratracheal instillation of asbestos fibres leads to parabronchial and intraalveolar granulomatous tissue reactions and bronchial epithelial regenerations. For further elucidation of the pathogenesis of…
