Abstract
Histological sections of cerebral motor cortex, brainstem, and spinal cord from 10 cases of clinically diagnosed motor neurone disease (MND) and 10 control cases were examined by conventional histology and immunocytochemical methods to localise ubiquitin. Intracytoplasmic inclusion bodies were identified in motor neurones of hypoglossal nuclei and appeared specific for MND. Similar inclusions were found in both large pyramidal cells and small neurones in the motor cortex, and were restricted to 4 cases having the amyotrophic lateral sclerosis form of MND with severe degeneration of corticospinal tracts. As reported in earlier studies, cellular inclusion bodies were identified in motor neurones of spinal cord from cases of MND but not in control material. Ubiquitin inclusions in motor neurones appear to be markers for the degenerative process causing neuronal loss in MND and there appears to be a close association between the anatomical location of inclusions and clinical manifestations of disease.

Abstract
The resting human microglia have previously been shown to be cells of dendritic morphology expressing class II MHC antigens and macrophage specific antigens by immunocytochemical techniques. To examine the relationship between the microglia and the family of dendritic antigen presenting cells (APC), normal white matter from eight normal adults with no neurological disease at autopsy was examined by immunocytochemical techniques to localize antibodies to leukocyte common antigen (LCA), HLA-DR, CD1 (T6), CD4 (T4), and glial fibrillary acidic protein. In addition, enzyme histochemical staining for ATPase, non-specific esterase (NSE), and acid phosphatase (ACP) was performed. The normal microglia are ATPase +ve, NSE -ve, ACP -ve, HLA-DR +ve, LCA +ve, CD1 (T6) +ve and weakly CD4 (T4) +ve. This specialized phenotype closely resembles that of Langerhans cells and suggests that microglia are not simply quiescent phagocytes, but may have a primary role as microenvironmentally specialized APC. The finding of weak anti-CD4 (T4) immunoreactivity supports suggestions for a central role for this cell in infection of the central nervous system by human immunodeficiency virus type 1.

Abstract
4-year-old's knowledge of counting and cardinality--the last count word reached represents the numerosity of the set--was tested in 2 experiments. Experiment 1 investigated the nature of early cardinality responses by presenting different forms of the cardinality question before, after, and before and after the child counted. Both type and time of question has large effects. Experiment 2 examined whether children of this age could recognize errors in 4 counting procedures and whether they would reject a cardinality response arrived at through a mistaken counting procedure. The children were very good at recognizing a standard counting procedure as correct. They had only limited success at treating procedures that violated the stable order of count words or violated the one-one correspondence between count word and object as incorrect. They lacked an understanding of the order irrelevance in that they judged valid, nonstandard counting orders as incorrect. The children did not seem to link their evaluation of a cardinality response with their evaluation of the counting procedure used to reach that response. The results do not indicate that counting principles initially govern the child's acquisition of counting knowledge. They are consistent with the suggestion that early cardinality responses are last-word responses.

Abstract
We have recently described an 18-kilodalton polypeptide (p18) that is present in much greater abundance in acute leukemic blast cells (myeloid and lymphoid) than in resting or proliferating nonleukemic lymphoid cells or chronic lymphoid and myeloid leukemic cells. In this report we describe the cloning of two different sized full-length cDNAs that code for p18. The two cDNAs differ in their 3'-noncoding regions as a result of alternative polyadenylation. Analysis of the complete nucleotide sequence and the corresponding amino acid sequence did not reveal significant homology to any previously described sequences. We show evidence that this gene is highly conserved in several animal species and low stringency hybridization studies suggest that the p18 gene may be a member of a family of partially homologous genes in the human genome.

Abstract
We have examined the effect of single dose indomethacin 50 mg on objective measurements of psychomotor function and whether this effect is altered by pretreatment with indomethacin 25 mg t.i.d. for 7 days in 10 healthy volunteers (5 male, 5 female; age 20-54 y). One hour after a single dose of indomethacin 50 mg there was significant impairment of psychomotor function (critical flicker fusion frequency threshold and choice reaction time) (Wilcoxon p less than 0.05). Pretreatment with indomethacin 25 mg t.i.d. for 7 days prevented this impairment. Thus we conclude that tolerance occurs over the course of a week to the psychomotor effects of indomethacin.

Abstract
A restriction fragment of the coding region of a human ubiquitin gene has been used in Northern analyses of RNA prepared from human motor cortex and anterior horn region of cervical spinal cord. The analyses show that there is a substantial increase (approximately two-fold) in the expression of a polyubiquitin gene in motor cortex and spinal cord from patients with motor neurone disease compared to these tissues from control cases. Polyubiquitin gene expression in other organisms is associated with physical or chemical cell stresses. The data indicate that the primary stresses which result in the generation of ubiquitinated filamentous inclusion bodies in neurones in motor neurone disease also result in increased transcription of a gene coding for a polyprotein of ubiquitin.

Abstract
Fifteen cases of diffuse Lewy body disease were diagnosed on pathological grounds during a single year in one health district. The range and frequency of clinical features contrast strikingly with previous reports. The majority of cases presented with classical levodopa-responsive Parkinson's disease either alone (6 cases) or with mild cognitive impairment (3 cases); the remaining 6 cases presented with cognitive impairment alone. In time almost all patients developed both dementia and Parkinsonism. The dementia was cortical in type, but unusual in that most (12 cases) showed day-to-day fluctuation in severity at some point in their illness. These findings suggest that diffuse Lewy body disease is not rare, and that it presents in a range of ways from dementia with subsequent Parkinsonism to Parkinson's disease with subsequent dementia. The latter mode of presentation suggests that it should be considered as a significant pathological substrate of dementia in Parkinson's disease.

Abstract
Central venous catheters have proven to be an important aid for the care of pediatric patients with malignancies receiving chemotherapy. A rare complication of such catheters is pulmonary septic emboli. This report describes a 15-year-old white girl with rhabdomyosarcoma who developed pulmonary nodules while on chemotherapy. These lesions appeared to be metastatic rhabdomyosarcoma. However, an excisional biopsy showed the lesions to be septic emboli. The patient was placed on antibiotic therapy and responded well. She was able to continue with her "front-line" therapy because the nodules were confirmed not to be metastatic disease.

Abstract
Two infants with short-bowel syndrome and liver failure associated with obligatory parenteral nutrition received a composite allograft that consisted of en bloc liver, stomach, duodenum, pancreas, jejunum, and ileum. Solutions to the fatal complications in the first case resulted in a functioning composite splanchnic system in the second case. Despite a number of early complications, the small intestine and liver developed near-normal function until a monoclonal, malignant, B-cell lymphoproliferative disorder appeared. The analysis of these two cases supports three summary observations: the operative procedure can be safely performed in a metabolically compromised infant; intestinal allograft rejection, in this model, is controllable with existing immunosuppressive drugs; and this procedure appears to be associated with a uniquely high incidence of lymphoma. Since transplantation is a feasible solution to this devastating infantile disease, further development of this therapy must incorporate means of preventing lymphoma.

Abstract
Severe crush injuries with compartment syndrome were treated in five patients by an immediate one-stage procedure. This procedure included the assessment of skin flap viability with accurate debridement of devascularized tissues. It was performed according to the split-thickness skin excision technique. Compartment pressures were measured and the fasciotomies were performed through open wounds or separate medial and lateral incisions. The medial incision was extended to release the tarsal tunnel. Fractures were reduced and internally fixed and exposed bones were covered with locally transposed muscles. Skin grafts, taken earlier for the skin viability assessment, were meshed and applied to replace skin loss. All wounds and fractures healed uneventfully with no major functional loss. In multiple trauma, the physician should maintain a high index of suspicion for early diagnosis and treatment of severe foot injuries. Early treatment leads to more desirable results, shorter hospitalization, and faster rehabilitation.

Abstract
By using pairs of monoclonal antibodies (MAbs) to different epitopes on CD21 and CD23 antigens, it has been shown that both antigens are readily detectable in cell-free supernates of cultures of B cells expressing these antigens on the cell surface. The antigens remained in the soluble fraction after high speed centrifugation. Sera from normal individuals contained significant amounts of CD21 antigen, whereas little CD23 antigen was detectable. By contrast CD23 but not CD21 antigen was present in urine. Sera from patients with B cell chronic lymphocytic leukaemia (B-CLL) contained increased amounts of both antigens. The levels were related to the surface expression of antigen on the leukaemic cells and the number of cells in the blood. The possible functional role of soluble forms of B cell antigens and the diagnostic potential of their detection in body fluids are discussed.

Abstract
Cells of 7 EBV-B-LCL, 10 Burkitt lines and 13 EBV-B-LCL/Burkitt line hybrids have been phenotyped for antigens of the major B cell clusters and for some other antigens. High levels of CD23 and CD39 and low levels of CD38 (T10) were characteristic of EBV-B-LCL; the converse was true for Burkitt lines. In hybrids the EBV-LCL phenotype was dominant. The phenotype of Burkitt-line cells correlated strongly with that of germinal centre B cells in tonsil sections, but differed markedly from that of marginal zone B cells or follicular mantle cells. The results are discussed in relation to the origin of Burkitt tumours of "sporadic" and "endemic" type, in particular to histopathological evidence that Burkitt lymphomas develop in germinal centres. Recent studies on the location of the breakpoints of Burkitt chromosomal translocations are also considered to be compatible with this concept, even though different regions of the immunoglobulin heavy chain locus are involved in the two types of BL.

Abstract
Immunocytochemical localization of the cell stress-associated protein ubiquitin was performed on human lesions containing Rosenthal fibres. Ubiquitin was localized around the periphery of classical Rosenthal fibres but not in the amorphous central areas; the ubiquitin-positive regions corresponded to the immunocytochemical localization of glial fibrillary acidic protein (GFAP). Compact bundles of GFAP in glial processes without a non-staining core were also associated with ubiquitin, while loosely aggregated cellular GFAP was not. The relationship between compact bundles of GFAP and the amorphous osmiophilic central component of Rosenthal fibres has been uncertain. These data, however, show that the compact bundles of glial filaments are distinct from normal GFAP in being associated with ubiquitin. A role for ubiquitin in Rosenthal fibre formation is suggested. We propose that the term Rosenthal fibre be restricted to mean the hyaline amorphous core of these structures, while realizing that this is based on a wider abnormality of surrounding glial fibrillary acidic protein filaments.

Abstract
Two new cell lines with the phenotype of terminally differentiated B cells have been derived from the presentation bone marrow of a patient with plasma cell leukaemia. They express the same immunoglobulin (A1-kappa) as the original bone marrow cells. JJN-1 is an hypodiploid, slow-growing line with a plasmacytic morphology, which grows in medium with 15-20% fetal calf serum. When JJN-1 was stimulated with a supernatant ('ESG') containing B cell stimulatory factor 2 (BSF-2/IL-6), a hypotetraploid sub-line, JJN-2, was selectively stimulated. JJN-2 is dependent on ESG for survival. The stimulatory effect of ESG can be completely abrogated by an anti-BSF-2 monoclonal antibody. However, purified BSF-2 alone only produces sub-maximal stimulation of the lines. Both lines show complex karyotypic abnormalities, including 14q- and del(6q). JJN-1 and JJN-2 may be useful for the study of late B cell differentiation and for use as immunogens for the generation of anti-plasma cell monoclonal antibodies.

Abstract
Brainstem and cortical Lewy bodies in diffuse Lewy body disease show intense immunoreactivity to antibodies against ubiquitin. Quantitative studies show that the novel neuropathological technique of anti-ubiquitin immunocytochemistry is more than twice as sensitive as conventional haematoxylin and eosin stains in detecting cortical Lewy bodies. Anti-ubiquitin immunocytochemistry should be regarded as the method of choice for the diagnosis and quantification of diffuse Lewy body disease.

Abstract
Using an immunocytochemical method to localise antibodies to ubiquitin, filamentous inclusion bodies were seen in spinal anterior horn neurones in cases of motor neurone disease (MND) but not in any control cases. These inclusion bodies appeared to be closely associated with classical Bunina bodies and immuno-electron microscopy suggested that they were based on arrays of straight 10-15 nm filaments together with some granular material. These observations link the protein ubiquitin with a chronic neurodegenerative disease and extend previous observations of a close association between filamentous inclusion bodies and ubiquitin. Ubiquitin-filament inclusions should be regarded as a new hallmark in the histological diagnosis of MND.

Abstract
Ubiquitin has been shown to be a component of neurofibrillary tangles in Alzheimer's disease. We now show immunocytochemically that it is also a component of neurofibrillary tangles in several other neurodegenerative diseases of diverse aetiology, including Down's syndrome, dementia pugilistica and postencephalitic parkinsonism, and in normal ageing. Ubiquitin immunoreactivity is not, however, generally found in the neurofibrillary tangles of progressive supranuclear palsy. These findings show that while associated ubiquitin is not a feature unique to the tangles of Alzheimer's disease, it is not simply a non-specific response to the presence of an inclusion body within the cell. The observations suggest that ubiquitin may have an important role in the formation of neurofibrillary tangles in a variety of neurodegenerative diseases.

Abstract
Polyclonal antibodies were raised which have a high affinity for conjugated ubiquitin. Immunocytochemistry was performed on paraffin sections of tissues showing well-characterized inclusion bodies. Ubiquitin was found as a component of the intermediate filament inclusion bodies characteristic of several major diseases including Lewy bodies of Parkinson's disease, Pick bodies of Pick's disease, Mallory bodies of alcoholic liver disease, cytoplasmic bodies of a specific myopathy, and Rosenthal fibres within astrocytes. Ubiquitin was also present in the three histological lesions characteristic of Alzheimer's disease. These observations suggest a fundamental role for ubiquitin in the formation of intermediate filament inclusion bodies in man, and have implications regarding the pathogenesis of these important diseases.
