The pathological response and translocation of a commercial chrysotile product similar to that which was used through the mid-1970s in a joint compound intended for sealing the interface between adjacent wall boards was evaluated in comparison to amosite asbestos. This study was unique in that it presents a combined real-world exposure and was the first(More)
The marked difference in biopersistence and pathological response between chrysotile and amphibole asbestos has been well documented. This study is unique in that it has examined a commercial chrysotile product that was used as a joint compound. The pathological response was quantified in the lung and translocation of fibers to and pathological response in(More)
A teacher with breathlessness of insidious onset developed acute symptoms on return home following his discharge from hospital. His flat was found to have extensive dry rot (Merulius lacrymans). Precipitins and specific IgE and IgG antibody against M. lacrymans were present and intracutaneous testing gave a typical dual skin reaction. Pulmonary physiology(More)
ELISA has emerged as a useful alternative to other more costly and complex tests. Polystyrene microhaemagglutination plates have been used as solid phase to absorb Aspergillus fumigatus protein and polysaccharide components for detection of specific antibodies in patients with various forms of pulmonary aspergillosis. IgG and IgE antibodies to the(More)
Minor modification of an existing readily available captive projectile weapon system has allowed development of a safe model for studying both penetrating ballistic and blunt tissue injury. A captive projectile weapon (defined as a firearm in which the projectile does not leave the weapon and in which the external wounding range is very limited) diminishes(More)
Clinical followup of 112 patients staged by the immunochemical determination of prostatic acid phosphatase from bone marrow aspirates is presented. This represents a 94 per cent (112 of 118) retrieval rate of a group studied more than 2 years previously. Of the 11 patients judged to be at high risk 4 (36 per cent) have suffered bony metastases, whereas only(More)
Chrysotile has been frequently used in the past in manufacturing brakes and continues to be used in brakes in many countries. This study was designed to provide an understanding of the biokinetics and potential toxicology following inhalation of brake dust following short term exposure in rats. The deposition, translocation and pathological response of(More)
This study was designed to provide an understanding of the biokinetics and potential toxicology in the lung and pleura following inhalation of brake dust following short term exposure in rats. The deposition, translocation and pathological response of brake-dust derived from brake pads manufactured with chrysotile were evaluated in comparison to the(More)
