Five physicians' radiological assessments of coalworkers' simple pneumoconiosis (CWP) in 2600 coalminers at 10 British collieries have been studied in relation to the individuals' estimated lifetime (mean 33 years) exposure to respirable coalmine dust. Estimates of exposure were based on 20 years of observations at each colliery. Radiographic(More)
General mortality in approximately 25 000 British coalminers over 22 year periods ending in 1980 was 13% lower on average than in English and Welsh men in the same regions of Britain. There were significant within region variations between collieries, and standardised mortality ratios increased during the later years of the follow up, approaching or(More)
The postnatal growth of the pre-acinar or conducting airways of the lung was examined by measuring the dimensions of selected axial pathways in lungs at different stages of development. The material included both formalin-fixed specimens and bronchograms. A method of comparing the relative sizes of each part of the pathways was developed which allowed for(More)
Individual choroid plexuses of human fetal brain at different developmental stages were investigated by an indirect immunoperoxidase technique. The number and distribution of prealbumin-, albumin-, alpha-fetoprotein-, transferrin-, IgG-, IgA-, IgM- and alpha 1-antitrypsin-containing choroid plexus epithelial cells were recorded. The distribution of(More)
The various histologic components of 39 germ cell tumors of the testis were studied with indirect labeled immunoperoxidase technique for the presence of the following tumor-associated antigens: alpha-fetoprotein (AFP), alpha 1-antitrypsin (A1AT), chorionic gonadotropin (HCG), specific pregnancy beta 1-glycoprotein (SP1), human placental lactogen (HPL),(More)
