    Notes: The pattern of basement membrane deposition was investigated in benign and malignant choroid plexus tumours using an immunocytochemical method to detect laminin, an intrinsic basement membrane component. The results were compared with intracranial ependymomas and myxopapillary ependymomas of the filum terminale. Expression of the intermediate filaments cytokeratin and glial fibrillar acidic protein (GFAP) and the epithelial marker carcino-embroyonic antigen (CEA) was also assessed. Laminin was detected in a subepithelial location in all the choroid plexus tumours but in none of the ependymomas, although basement membrane fragmentation was seen in the choroid plexus carcinomas. In contrast. GFAP was present in all the types of tumour examined. Cytokeratin (as detected by CAM 5.2) was present in all the choroid plexus lesions and also in the ependymomas arising in the spinal canal. CEA was not detected. We conclude that immunostaining for laminin assists distinction between choroid plexus tumors and papillary ependymomas and between benign and malignant choroid plexus tumours.

    Glomerular perfusion in renal allograft biopsies (1993)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: In the commonest causes of impaired renal transplant function there is reduced renal and glomerular perfusion. We investigated the possibility of identifying this phenomenon in renal transplant biopsies, by the crude but simple method of counting the mean numbers of glomerular capillary loops which contained erythrocytes. In cyclosporin toxicity, acute tubular necrosis and in acute cellular rejection there was a considerable reduction in the numbers of erythrocyte-containing glomerular capillaries. The separation of the acute tubular necrosis group from normal was almost complete. This feature is therefore not specific but appears to correlate well with states of impaired glomerular perfusion. We suggest that a simple assessment of glomerular erythrocyte ‘load’ forms a useful part of the histological examination of renal transplant biopsies.

    Basement membrane continuity in benign, premalignant and malignant epithelial conditions of the uterine cervix (1990)

    Notes: The pattern of basement membrane deposition in the uterine ectocervix was assessed in benign, premalignant and malignant conditions, using an indirect immunoperoxidase technique to detect laminin, an intrinsic basement membrane component. A semi-quantitative approach was used to assess the frequency of small break in the basement membrane. The cervical squamous epithelium in benign epithelial conditions has an almost completely continuous basement membrane, but the development of viral atypia or cervical intraepithelial neoplasia (CIN) is associated with the appearance of small basement membrane breaks. There is a correlation between increasingly severe CIN and increasing numbers of breaks, and there is a concurrent increase in the numbers of subepithelial inflammatory cells. The development of invasive neoplasm is associated with a sudden change to a fragmented pattern of basement membrane deposition, a finding which is of potential diagnostic use.
