    Notes: Herpes simplex viral DNA was detected in biopsy specimens obtained from four patients with Kaposi's varicelliform eruption using an in situ hybridization technique with btotinylated complementary DNA probes. Herpes simplex viral DNA was consistently found almost exclusively in the nuclei of giant cells and balloon cells in vesicles during day 2, 5 and 7 of the disease. In the nuclei, the viral DNA staining pattern was granular or agglomerate. No positive staining was observed in the cytoplasm.

    Reactive oxygen intermediates in autoimmune islet cell destruction of the NOD mouse induced by peritoneal exudate cells (rich in macrophages) but not T cells (1994)

    Notes: Summary The non-obese diabetic (NOD) mouse spontaneously develops autoimmune Type 1 (insulin-dependent) diabetes mellitus. NOD mice exhibit massive infiltrates of T cells and macrophages into pancreatic islets (insulitis) prior to diabetes. The contribution of oxygen free radicals to the development of insulitis in NOD mice was examined by administration of its scavengers, such as superoxide dismutase and catalase. Bovine superoxide dismutase and catalase were each coupled to polyethylene glycol. The treatment with superoxide dismutase-polyethylene glycol reduced the number of islets with insulitis and increased the undamaged islet tissue, as compared with the control group. The treatment with catalase-polyethylene glycol showed a similar tendency which did not reach significance. Using a flow cytometric assay of the oxidation of 2′, 7′-dichlorofluorescein, the content of reactive oxygen intermediates in islet cells in the culture system was measured and the effect of peritoneal exudate cells and T cells on their production examined. Peritoneal exudate cells, but not T cells, from NOD mice increased the content of reactive oxygen intermediates in islet cells of either the NOD mouse or the ILI mouse (MHC-identical to NOD); the addition of superoxide dismutase to the culture medium suppressed this increase in NOD or ILI islet cells. The present data support the concept that production of oxygen free radicals mediated by macrophages can damage islet beta cells, directly resulting in autoimmune Type 1 diabetes in NOD mice.

    Ultrasound examination of caesarean section scars during pregnancy (1991)
    Springer

    Notes: Summary Two hundred and sixteen transverse caesarean section scars were examined sonographically near term by a conventional method (175 scars) and a new method (41 scars). The new method consisted of obtaining a transabdominal longitudinal scan by the conventional method and also by a 3M conductor, a transabdominal frontal scan to give a surface view of the scar, and transperineal and transvaginal longitudinal scans. The new method was used from 16 weeks of gestation onwards. Of 41 scars scanned by the new method, 31 showed good healing, being more than 2 mm in thickness throughout; 10 scars showed poor healing with a thickness of less than 2 mm and loss of continuity. Of 31 patients with good healing, 8 delivered vaginally and the remaining 23 patients had repeat caesarean sections for other obstetric indications. All patients with ultrasound evidence of poor healing had repeat caesarean sections. At operation the thickness of the lower uterine segment was measured with ophthalmic calipers. There were 4 false negative results (4/83: 4.8%) and 1 false positive result (1/43: 2.3%) with conventional ultrasound and no false positives or false negatives with the new method.

    The favourable effect of cyclophosphamide pulse therapy in the treatment of massive pulmonary haemorrhage in systemic lupus erythematosus (1994)

    Notes: Abstract. Pulmonary haemorrhage (PH) is a rare but very serious complication of systemic lupus erythematosus (SLE) and the treatment is still controversial. Some authors showed the effectiveness of methylprednisolone pulse therapy for PH, although its effect was often transient. A 12-year-old Japanese girl with lupus nephritis and recurrent massive PH in SLE was treated with methylprednisolone pulse therapy. The effect on PH was transient and she needed three cycles within a month and side-effects developed. Pulse therapy with cyclophosphamide, synchronized with plasmaphaeresis, was tried. Thereafter she did not experience PH for 7 months, whereas lupus nephritis did not improve. Pulse cyclophosphamide would be effective for life threatening massive PH in SLE patients.

    Morphology and modes of cell proliferation in earliest signet-ring-cell carcinomas induced in canine stomachs byN-ethyl-N′-nitro-N- nitrosoguanidine (1991)

    Notes: Summary Signet-ring-cell carcinomas were induced in the stomach of 12 beagle dogs by p.o. administration ofN-ethyl-N′-nitro-N-nitrosoguanidine (ENNG), and the morphology and modes of cell proliferation in an incipient stage of cancer growth were studied with bromodeoxyuridine (BrdUrd) incorporation. From 5 to 27 months after the completion of 8 months' carcinogen treatment, minute carcinomas were found in the stomachs of 9 dogs. Before sacrifice, the dogs were given a single or repeated i.v. injections of BrdUrd for 1–3 days. Minute signet-ring-cell carcinomas were found to form a layered structure, in which the cancer cells proliferated in the lamina propria at the gland-neck level and differentiated to postmitotic signet-ring cells at the upper and lower levels of the mucosa. From repeated injections of BrdUrd, the time required for all the proliferative cells to be labelled with BrdUrd (reflecting the maximum cellcycle time) was estimated to be 1.7 days for the normal glands, and 2.7 days for minute signet-ring-cell carcinomas. From the labelling index with BrdUrd as well as from the morphology, earliest carcinomas were identified in the single gland. There remained atrophic normal epithelium commonly in the single-gland lesions. Proliferative atypical cells appeared to be shed into the stroma passively through the atrophy and subsequent collapse of the gland rather than through active invasion. This may be a reason why cancer cells in minute signet-ring cell carcinomas preserved the normal pattern of cell renewal movement to form the layered structure.

    Double labelling of major histocompatability complex molecules and lysosomal protein lamp-1 on human dendritic cells (1994)

    Notes: Summary In this study, double labelling for major histocompatability complex (MHC) class I and class II molecules and for MHC molecules and the lysosomal membrane protein lamp-1 on ultrathin cryosections of dendritic cells isolated from human peripheral blood was performed. The plasma membrane proved to be positive for both MHC class I and MHC class II molecules and was labelled for only a very few lamp-1 molecules. MHC class I and MHC class II molecules did not co-localize intracellularly except in some peripherally located vesicles. However, many MHC class II-labelled vesicles were present in a juxtanuclear position but only some of them were co-labelled for lamp-1. These results indicate the presence of a separate, non-lysosomal compartment for class II molecules in dendritic cells.
