Abstract
The myelin basic protein (MBPi) accounts for the main encephalitogenic antigen of the demyelinating encephalopathy, but other myelin elements also be noted by some articles. We tried to determine the relationship between W1 protein and the demyelinating encephalopathies. The 2',3'-cyclic nucleotide 3'-phospho-diesterase(CNPase, a gift from Dr. Yasuzo Tuskada) monoclonal antibody was used as a probe to study the W1 protein level in 5 different demyelinating encephalopathies and 2 normal adult brains with immunocytochemical technique. Two different demyelinating types of W1 protein level were found out. Type 1 showed the W1 protein level parallel with demyelinated feature in general pathology whereas the type 2 showed demyelinated in the general pathology but the W1 protein level was normal in the immunocytochemical study. Multiple system degeneration, Binswanger's disease and postvaccinal encephalopathy of type B encephalitis belong to type 1 and multiple sclerosis and Balo's concentric sclerosis belong to type 2. These results might indicate the different pathogenesis of demyelinating encephalopathies.

Abstract
In previous studies we have described a process whereby an erythrocyte in biochemical distress can initiate its own removal by macrophages of the reticuloendothelial system. This process involves the clustering of the integral membrane protein band 3 by denatured haemoglobin and the subsequent recognition of the exofacial poles of clustered band 3 and associated proteins by autologous antibodies. To determine whether this clearance pathway might mediate normal cell turnover, the fraction of normal erythrocytes containing the 0.5% densest cells, which are known to be destined for immediate removal, was isolated and characterized biochemically. This densest fraction was found to contain 6 times more membrane-bound globin (haemichromes) and 10 times more surface-bound autologous IgG than the other fractions containing cells of lower density. To determine whether the autologous IgG was physically associated with the haemichrome-stabilized membrane protein clusters, a procedure was developed for isolation and characterization of the microscopic aggregates. The isolated aggregates were found to contain a disulphide-cross-linked mixture of several membrane proteins, predominantly haemichromes, spectrin and band 3. Although the aggregates constituted only 0.09% of the total membrane protein, they still contained approximately 55% of the total cell-surface IgG. Since in control studies anti-(blood group A) antibodies, which are distributed randomly over the surface of type A cells, could not be recovered in the aggregate, we conclude that the autologous cell-surface IgGs were physically associated with the membrane protein clusters when they were co-isolated with them in our procedure. Thus the 640-fold enrichment of autologous IgG in the aggregates compared with regions of the membrane devoid of tightly clustered protein suggests that sites of integral protein clustering either are non-specifically sticky to IgG or are viewed as foreign or 'non-self' by the immune system and aggressively opsonized with IgG.

Abstract
Orientation to the specialty of home healthcare nursing in a Medicare-certified agency is not easy. In addition to clinical competency, the nurse must be able to document for and communicate with the fiscal intermediary. Documentation must be completed to meet the requirements of the site visitors from the site certifying agency as well as accrediting agencies. More recently, quality of care issues are of interest to the peer review organizations. Administrators, supervisors, and staff must be involved in this important process to attract and retain new as well as experienced nurses. A comprehensive orientation program that addresses the expectations of the agency as well as the external reviewing organizations and prepares the staff to meet these expectations is essential for providing quality home healthcare services.

Abstract
The DNA content of breast tumours from 170 patients who presented between 1978 and 1980 was measured by flow cytometry. The relationship between tumour ploidy and disease outcome was assessed and its association with other prognostic factors evaluated. Compared with those with diploid tumours, patients with aneuploid tumours had significantly earlier relapse and shorter survival (P less than 0.0001). Tumour ploidy was strongly related to grade (P less than 0.001), but there was no significant association between DNA ploidy and c-erb-B-2 expression, lymph node status or tumour size. In lymph node negative and c-erb-B-2 negative patients, aneuploid tumours were associated with a poorer prognosis (P less than 0.001) than diploid tumours. Multivariate analysis showed that tumour ploidy gave independent information on disease free and overall survival. Tumour ploidy may be used as an independent prognostic variable in patients with breast cancer and it may be helpful in defining patients within the node negative or c-erb-B-2 negative groups likely to have a poor outcome who might benefit from adjuvant treatment.

Abstract
Morphological observations suggest a close association between heterochromatin and the nuclear lamina. To investigate the molecular aspects of this association, we have established a simple sedimentation assay employing purified lamin proteins, or their 125I-labeled derivatives, and polynucleosomal particles isolated from avian erythrocytes. We report here that purified, unlabeled lamin A and 125I-lamin A, but not 125I-lamin B or 125I-bovine serum albumin, bind to polynucleosomes in a saturable and specific fashion. The specific binding of 125I-lamin A is of high affinity (Kd = approximately 1 x 10(-9) M) and is distinctly temperature-dependent. This interaction is not affected by exogenous polyionic agents such as polylysine and DNA, but it can be abolished by protease digestion of the polynucleosomes. These data suggest that nuclear lamin A maintains a direct association with a proteinaceous constituent of interphase chromatin.

Abstract
A method is presented for preservation of isolated intact chloroplasts and isolated thylakoids for use in chloroplast protein import and thylakoid protein integration studies. Chloroplasts of pea (Pisum sativum) were preserved by storage in liquid nitrogen in the presence of a cryoprotective agent. Dimethyl sulfoxide was the most effective of several cryoprotectants examined. Approximately 65 to 70% of chloroplasts stored in liquid nitrogen in the presence of dimethyl sulfoxide remained intact upon thawing and were fully functional for the import of precursor proteins. Imported proteins were correctly localized within these chloroplasts, a process that for two of the proteins tested involved transport into the thylakoids. Lysate obtained from preserved chloroplasts was functional for protein integration assays. Preserved chloroplasts retained import and localization capability for up to 6 months of storage. Thylakoids were preserved by a modification of a method previously described (Farkas DL, Malkin S [1979] Plant Physiol 64: 942-947) for preservation of photosynthetic competence. Preserved thylakoids were nearly as active for protein integration studies as freshly prepared thylakoids. The ability to store chloroplasts and subfractions for extended periods will facilitate investigations of plastid protein biogenesis.

Abstract
In a previous series we have shown poor short-term (3-5 years) survival for patients with tumours overexpressing the c-erbB-2 oncoprotein. In this study we employed archival paraffin-embedded tissue from patients who underwent mastectomy 10-12 years prior to assessment (n = 187). Immunohistochemical staining was carried out by an indirect immunoperoxidase technique using the novel monoclonal antibody NCL-CB11. Tumours were scored according to intensity of membrane staining. Patient and tumour information was obtained by scrutiny of clinical records. Survival analysis was carried out for both time to relapse and time to death, using the log rank test. Patients with tumours demonstrating intense membrane staining had a poor prognosis compared with the rest, with a steeply sloped survival curve over the first 4 years; the survival difference was still evident at 12 years follow-up (P less than 0.001). The survival advantage for c-erbB-2 negative patients was maintained in lymph node negative patients (P less than 0.001). However, c-erbB-2 status did not influence survival in the node positive group, where all patients had a uniformly poor outlook. These results applied to both time to relapse and time to death. In conclusion, c-erbB-2 status, determined using NCL-CB11, is a powerful prognostic indicator, defining in particular node negative patients with a particularly poor prognosis, and for whom alternative therapeutic strategies may be appropriate.

Abstract
The 160 and 200 Kd phosphorylated and non-phosphorylated neurofilament monoclonal antibodies were used as the probe to study the cytoskeletal protein distribution inside cerebral neurons of 2 normal adults and 2 patients with Alzheimer's disease (AD). Immunocytochemical technique was applied in this study. Non-phosphorylated neurofilament was located in the perikarua, whereas, the phosphorylated neurofilament was rich in the peripheral of the neuron's cell body and axons in the normal adult brain. In AD, no significant difference was seen when non-phosphorylated neurofilament was compared with normal adult brain; but phosphorylated neurofilament was seen accumulated inside the neuron's cell bodies. We did not find any immunoreactivity of the above cytoskeletal proteins in the senile plaques. These results indicate that the accumulation of high molecular weight phosphorylated neurofilament inside the neuron's cell bodies is the early pathogenetic change of AD.

Abstract
In an earlier paper, we reported the development of (+-)-7-iodo-8-hydroxy-3-methyl-1-(4'-azidophenyl)-2,3,4,5-tetrahydro- 1H-3-benzazepine (I-MAB) and its 125I analogue ([125I]I-MAB) as selective, high affinity photoaffinity labels for the D-1 dopamine receptor. In this report, we now describe the complete synthesis and resolution of I-MAB and the pharmacological characterization of the stereoisomers in canine striatal membranes. R-(+)-I-MAB showed highly specific dopamine D-1 receptor binding (KD = 0.28 nM) and binds selectively and stereoselectively to the D-1 receptor. These results further confirm the previous suggestion that, in the benzazepine series of DA agonists and antagonists, the activity principally resides in the R-(+) enantiomer, the S-(-) enantiomer being considerably less potent or inactive. Moreover, R-(+)-[125I]I-MAB, upon photolysis, identifies the ligand-binding subunits of the neuronal D-1 receptor, with an apparent Mr of 74,000, 62,000, and 51,000 as assessed by autoradiography following sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Photoincorporation of R-(+)-[125I]I-MAB into these polypeptides was stereoselectively blocked by D-1 dopaminergic ligands with an appropriate pharmacologic profile for the receptor. R-(+)-[125I]I-MAB should thus prove to be a useful stereoselective photoaffinity label for the further characterization of the D-1 receptors.

Abstract
Using a solution binding assay, we show that purified 125I-labeled lamin B binds in a saturable and specific fashion to lamin-depleted avian erythrocyte nuclear membranes with a Kd of approximately 0.2 microM. This binding is significantly greater than the binding of 125I-labeled lamin A and is competitively inhibited by unlabeled ligand. We demonstrate that a 58-kDa integral membrane protein (p58) is a lamin B receptor by virtue of its abundance in the nuclear envelope and association with 125I-labeled lamin B in ligand blotting assays. Specific antibodies raised against p58 recognize one protein in isolated nuclei and partially block 125I-labeled lamin B binding to lamin-depleted nuclear membranes. Cell fractionation and indirect immunofluorescence microscopy show that p58 is located in the periphery of the nucleus. This protein may serve as a membrane attachment site for the nuclear lamina by acting as a specific receptor for lamin B.

Abstract
We describe a method for permeabilizing and extracting cells that preserves both structure and function whilst allowing the cell derivatives to be handled freely. Cells are encapsulated in microbeads of agarose; the coat of agarose, which is freely permeable to small molecules, forms a protective layer around fragile cell constituents. Cells are then permeabilized by the non-ionic detergent Triton X-100 or antibody and complement in a buffer whose ionic composition mimics that of the cytoplasm. The resulting structures have been characterized morphologically (by immunofluorescence and electron microscopy) and biochemically. Lysis with Triton removes both cell and nuclear membranes, and extracts most of the cytoplasm to leave chromatin surrounded by cytoskeleton; nucleus and cytoplasm then become accessible to triphosphates, enzymes and antibodies. Lysis with complement permeabilizes the cell membrane but leaves the nuclear membrane intact; triphosphates and restriction enzymes, but not antibodies, can then enter both nucleus and cytoplasm. Both types of lysis yield preparations whose chromatin template remains essentially intact, and which is replicated and transcribed at rates close to, or greater than, those found in vivo. Treatment of complement-lysed cells with Triton reduces the very efficient DNA synthesis, implying that the nuclear membrane is involved, directly or indirectly, in replication.

Abstract
The distribution of ATPase-positive Langerhans cells (LC) was investigated in 117 specimens of normal adult human skin and mucosa taken from different areas of the body. Although there were significant variations in the numbers of LC in each area examined, skin from the face and neck contained the highest density of cells (976 +/- 30.93/mm2). The densities of LC in trunk skin (740 +/- 28.97/mm2), scalp (693 +/- 69.56/mm2) and arm or leg skin (640 +/- 40.95/mm2) were similar. Buccal mucosa had significantly fewer LC (567 +/- 42.94/mm2) than trunk skin, and sacrococcyx skin and palm and sole skin displayed the smallest number of these cells (267 +/- 56.14/mm2 and, 189 +/- 19.15/mm2 respectively). No ATPase-positive LC were detected in the centre of two corneal specimens.
