Quantitative analysis of “synaptic” ribbon profiles in the pineal complex of male and female Pirbright-White guinea pigs

Summary Previous studies have pointed in the direction of sex differences as well as regional differences in the pineal gland of guinea pigs. In the present investigation these aspects were studied at the electron-microscopic level by quantitating different types of synaptic bodies, intrinsic to pinealocytes. The two major types of synaptic organelles, ribbons and spherules, did not exhibit regional or sex differences. Synaptic structures intermediate in appearance to ribbons and spherules were significantly larger in number in males in the distal region of the pineal gland, compared to females. As previous studies have shown that ribbon and spherule numbers undergo characteristic changes depending on the functional state of the pineal gland, it is concluded that, as far as the synaptic organelles are concerned, no clear-cut sex or regional differences appear to exist in the guinea pig pineal gland.     

Ultrastructure of peripheral nerve in metachromatic leucodystrophy

Summary An electron microscopical study of two consecutive nerve biopsies from a patient with metachromatic leucodystrophy (sulphatide lipidosis) was made. The ultrastructural changes observed consisted of: a) irregular whorls of myelin. The myelin in the whorls showed a thickened, sometimes doubled, intraperiod line, which was barely visible in compact myelin; b) inclusion bodies up to 1 in diameter in the cytoplasm of Schwann cells. These had a lamellar structure, with stacked membranes 60 Å apart; c) a loose pattern of the myelin in some nerve fibers, with loss of the intraperiod line, and d) presence of abnormally dense mitochondria with thickened cristae in Schwann cells. It is suggested that: a) the whorl formation and the ultrastructural abnormalities of the myelin in the whorls may be due to impaired myelin synthesis, and b) that the inclusion bodies may represent the accumulation of cerebroside sulfate in micellar aggregates. The loose pattern of myelin is considered artifactural until proven otherwise.

Zusammenfassung Zwei aufeinanderfolgende Nervenbiopsien bei einem Patienten mit metachromatischer Leukodystrophie (Sulfatid-Lipoidose) wurden elektronenoptisch untersucht. Die beobachteten ultrastrukturellen Veränderungen bestehen in: a) unregelmäßigen Wirbelbildungen (whorls), in welchen das Myelin Verdickungen, manchmal Verdopplung des Zwischenstreifens (intraperiod line) aufweist, was im kompakten Myelin kaum sichtbar ist. b) Einschlußkörperchen mit einem Durchmesser bis zu1 im Cytoplasma der Schwann-Zellen. Diese weisen lamelläre Struktur mit einem Membranabstand von 60 Å auf. c) ein lockeres (loose) Myelinmuster mit Verlust des Zwischenstreifens in einigen Nervenfasern und d) Auftreten von abnorm dichten Mitochondrien mit verdicktem Cristae in Schwann-Zellen. Es wird angenommen, daß a) die Wirbelbildungen und die ultrastrukturellen Myelinabnormitäten in den Wirbeln einer gestörten Myelinsynthese entsprechen und b) daß die Einschlußkörperchen die Anhäufung von Cerebrosidsulfat in micellaren Verbänden darstellen. Das lockere Myelinmuster wird vorläufig als artifiziell angesehen.

Hyperkinetic children: Early indicators of potential school failure

Hyperkinetic children are identified as a population-at risk upon admission to kindergarten. The etiology of hyperkinetic behavior is controversial. Organic driveness, hyperkinetic behavior disorder, postencephalitic behavior, brain damage with behavioral and conceptual deficit, Strauss syndrome, have all been used to label essentially similar symptom constellations. Bypassing the area of controversy, a study is reported that demonstrates that children who were identified as hyperkinetic (using behavioral criteria developed in an earlier study) were (1) absent from school more frequently, and (2) did remarkably less well on standardized tests of school readiness than their peers rated nonhyperkinetic. The implications are discussed and suggestions made for the development of intervention programs.An earlier version of this paper was presented at the Annual Meeting of the American Orthopsychiatric Association, March, 1967.     

Immunohistochemical study on the distribution of α and β subunits of S-100 protein in brain tumors

Summary The immunohistochemical distribution of and subunits of S-100 protein (S-100, S-100, respectively) in 138 cases of human brain tumors was investigated by the avidin-biotin immunoperoxidase method. Brain tumors can be divided into four groups: group 1 [S-100 (+) and/or S-100 (+)]; astrocytoma, glioblastoma, ependymoma, subependymoma, oligodendroglioma, choroid plexus papilloma, gangliocytoma, meningioma, chordoma, malignant melanoma. Group 2 [S-100 (+) and S-100 (-)]; pineoblastoma, pituitary adenoma, craniopharyngioma, rhabdomyosarcoma. Group 3 [S-100 (-) and S-100 (+)]; acoustic Schwannoma. Group 4 [S-100 (-) and S-100 (-)]; medulloblastoma, malignant lymphoma, germinoma. The S-100 immunoreactivity pattern in brain tumors was similar to those obtained using conventional anti-S-100 protein sera. In the first group of brain tumors both the number of positively stained tumor cells and the staining intensity were generally greater for S-100 than for S-100 with a few exceptions including one gemistocytic astrocytoma, one subependymoma, one malignant melanoma, and some cases of glioblastomas. As to the relationship between malignancy and S-100 protein in glioma, S-100 immunoreactivity decreased according to degree of malignancy, while that of S-100 varied, suggesting a heterogeneity of tumor cells in glioblastomas. Immunostaining for S-100 and S-100 might become a useful diagnostic procedure in brain tumors and may give us more detailed and precise data of S-100 protein in brain tumors.     

Assessment of complicance-related attitudes in psychiatry

Summary In a study of 118 psychiatric patients two questionnaires of similar content that are supposed to predict compliance with pharmacotherapy in psychiatry were examined, COSS and KK-Skala. These questionnaires assess the patient's attitudes towards his illness, pharmacotherapy, and the physician. Patient compliance was judged by the treating physicians. The results of discriminant analyses indicated that about two thirds of the patients were correctly classified into compliant and moderately or not compliant (as judged by the physicians) by means of COSS and KK-Skala, respectively. It is a matter for further research whether these results reflect in fact moderate associations between patient attitudes and compliant behavior or are due to limitations of the questionnaires and of the study design.     

Somatosensory evoked potentials in patients with thalamic lesions

Summary Somatosensory evoked potentials (SEPs) were recorded in 20 patients with thalamic lesions confirmed by CT (10 with infarction, 10 with haemorrhage). The changes in SEP configuration are discussed in their relationship to clinical symptoms. Four types of SEP abnormality produced by thalamic lesion are distinguished: (1) FF type, (2) N20/P23 dissociation type, (3) N18/N20 false shift type, and (4) reduced early component type. It was shown that clinically similar lesions might produce different SEP patterns.     

Neuroectodermal tumors of the peripheral and the central nervous system share neuroendocrine N-CAM-related antigens with small cell lung carcinomas

Summary The current study describes the presence of neuroendocrine antigens of peripheral and central neural tumors using eight monoclonal antibodies raised to small cell lung carcinoma (SCLC), which recognize neural/neuroendocrine or neural antigens, as defined by their reaction pattern in normal tissues and tumors. At least five of them recognize different epitopes of the neural cell adhesion molecule (N-CAM). It was found that all of 12 neuroblastomas, 2 ganglioneuroblastomas and 4 ganglioneuromas as well as 23 central primitive neuroectodermal tumors, 13 astrocytomas and 4 ependymomas share neural/neuroendocrine antigens (as defined by the anti-N-CAM antibodies Moc-1,-21,-32,-52 and-191) with SCLC. The neural/neuroendocrine antigen defined by Moc-171 was also found in all peripheral tumors, but only in further differentiated central tumors. Non-N-CAM related neural antigens (as defined by Moc-51 and-172) were found only in better-differentiated peripheral and central tumors, but they could be demonstrated in all three medulloblastoma cell lines studied. In addition, the antigen defined by Moc-51 was demonstrated in an immunoblot of a neuroblastoma cell line. Antibodies recognizing epithelia antigens of SCLC and other epithelia and their tumors (Moc-31 and-181) were non-reactive. It was concluded that these findings give further support for a relation between neural and neuroendocrine tumors and that some of the antibodies may be useful for the detection of differentiation in neural tumors. Antibodies with an epithelia recognition pattern may serve to distinguish neural from neuroendocrine tumors.Supported by NIH grant CA 36245 W.M.M. was a Fullbright scholar     

Diagnosing Depression in African Americans

Since the 1970s, articles have noted the increased presence of psychotic symptoms among depressed African Americans, the presence of diagnostic bias identified when structured clinical interviews are used, and the identification of misdiagnosis of affective illness among chronically, mentally ill, African Americans. This paper reviews this literature and describes three alternative presentations of depressive illness among African Americans that differ from the DSM IV criteria for Major Depressive Disorder: the stoic believer, the angry, evil one with a personality change, and the John Henry doer. Clinicians are encouraged to recall these presentations of depression when evaluating African American patients.     

Variability of morphological features in early infantile polyneuropathy with defective myelination

Summary Four cases of early infantile polyneuropathy with defective myelination are reported. The peripheral nerve was studied by light and electron microscopy; different morphological characteristics have been noticed in these patients. Case 1 presented aspects of defective myelination with atypical onion bulb formation composed of multiple layers of basement membrane. In case 2, defective myelination and atypical onion bulb formation were associated with aberrant hypermyelination. Cases 3 and 4 were brothers, who presented axonal damage and atypical onion bulb formation.     

Psychometric properties of the parental bonding instrument in a spanish sample

Summary The Parental Bonding Instrument was translated into Spanish and administered to a sample of 205 Spanish primiparae 3 days after childbirth. Reliability, factorial structure and predictive validity for affective disorders were evaluated. The Spanish version of the PBI has psychometric features similar to those described in other cultures. However, the results suggest that in future research the predictive power of the Control factor in affective disorders might be improved by splitting it into two subfactors: Overprotection and Restraint.     

Ultrastructural changes in the anterior horn synapses of rat spinal cord under different locomotor conditions

Summary Ultrastructural changes in axodendritic synapses of the spinal cord ventral horn are studied in rats subjected to different locomotor conditions: immobilization, control and physical loading. Enhanced motor activity results in a reduction of the number of synaptic vesicles in the axon terminal, as well as flattening and diminution of their size. Other changes correlated with the different motor regimes are likewise established in the number of terminal ending's mitochondria, in active zones, in subjunctional dense bodies, and in the bouton area. Data are treated by means of variation analysis. The significance of differences is established by T-criterion.     

The significance of cytoplasmic inclusions in late infantile and juvenile amaurotic idiocy

Summary The electron microscopic findings of cerebral biopsies from two siblings with late infantile-juvenile amaurotic idiocy are presented. One patient had a mixture of fingerprint and multilamellar inclusions, often in the same cytosome. The second patient had only fingerprint inclusions.Electron microscopic findings in autopsied tissues from two other cases of late infantile-juvenile amaurotic idiocy with multilamellar cytosomes are also presented. Evolution of the multilamellar cytosomes into lipofuscin was not observed. We concluded that cases of late infantile-juvenile amaurotic idiocy with multilamellar and fingerprint inclusions should be distinguished from cases with lipofuscin.The present investigation was supported by Research Grants NS 05572-08, 1 T01 NS 05712-01 and RR 75.     

Comparison of integrin adhesion molecules expressed by primary brain lymphomas and nodal lymphomas

The expression of 17 adhesion molecules was immunohistochemically examined in 5 primary cerebral lymphomas (PCL) and in 5 histologically similar nodal lymphomas (NL) to evaluate their possible involvement in selective targeting of lymphoma cells to the brain. PCL and NL tumor cells showed very similar expression patterns: they were consistently positive for ₃, ₄ and ₁ integrin chains; negative for ₂, ₆, ₃ and ₄ integrin chains; and heterogeneous for ₅, _L, _M, _X, ₂ and ₇ integrin chains, as well as for intercellular adhesion molecule-1 (ICAM-1) and the selectin LECAM-1. Loosely infiltrating PCL showed lower levels of the _L2 integrin than compact cell clusters. Vessels stained for ICAM-1 and vascular cell adhesion molecule-1 (VCAM-1). We conclude that the adhesion molecules implicated in the extravasation of non-neoplastic leukocytes (₄₁/VCAM-1 and _L2/ICAM-1) are also expressed by both PCL and NL. The adhesion molecules examined are apparently not selective mediators of lymphoma cell homing to the brain, but at least _L2 integrin might be related to the infiltration pattern of PCL within the brain parenchyma.Supported by the Sander Foundation     

Does social deprivation during gestation and early life predispose to later schizophrenia?

Summary We employed a case-control study design to investigate whether schizophrenic patients differed from non-psychotic psychiatric patients in terms of place of birth and paternal occupation. Cases were first-contact schizophrenic patients ascertained from the Camberwell Cumulative Psychiatric Case Register. Controls were the next (non-psychotic) patient on the Register matched for age and sex. In comparison with controls, cases were more likely to have: (1) been born in the deprived innercity Camberwell catchment area (odds ratio 2.3), and (2) had fathers who had manual as opposed to non-manual occupations (odds ratio 2.1). The results were compatible with the notion that socio-economic deprivation during gestation and early life predisposes to later schizophrenia.     

Cortical regulation of subcortical dopamine systems and its possible relevance to schizophrenia

Summary A unique model of DA system regulation is presented, in which tonic steady-state DA levels in the ECF act to down-regulate the response of the system to pulsatile DA released by DA cell action potential generation. This type of regulation is similar in many respects to the phenomenon proposed to mediate the action of norepinephrine on target neurons; i.e., an increase in the signal-to-noise ratio as measured by postsynaptic cell firing (Freedman et al., 1977; Woodward et al., 1979). However, in this model the signal and the noise are neurochemical rather than electrophysiological. Furthermore, the noise (tonic DA in the ECF) actually down-regulates the signal (phasic DA release) directly, and thereby provides a signal of its own that affects the system over a longer time-course. Therefore, the difference between signal and noise may also depend on the time frame under which such determinations are made.     

Lack of correlation between DST results and urinary MHPG in depressed inpatients

Summary Abnormalities of noradrenaline metabolism and of the activity of hypothalamic-pituitary adrenal axis (HPA) have been reported in depression. To study the possible relationship between these 2 parameters, urinary excretion of 3-methoxy-4-hydroxy-phenylethyleneglycol (MHPG) and Dexamethasone Suppression Test (DST) were analyzed in 58 depressed patients. A positive correlation was found between the age of depressed patients and 24-h urinary excretion of MHPG. Twenty-two patients (38%) were DST non suppressors. Pre-DST plasma cortisol levels were significantly higher in non suppressors than suppressors. No difference was found however between urinary MHPG levels in supressors and non suppressors. There was no correlation between pre-DST plasma cortisol and levels of urinary excretion of MHPG. These results do not support the hypothesis of a relationship between these 2 parameters. However, when depressed patients were separated into two groups according to urinary excretion of MHPG (high MHPG and low MHPG), the high MHPG group included significantly more non suppressors then the low MHPG one. This result is not sufficient to demonstrate of link between HPA system activity and central noradrenaline metabolism.     

An electronmicroscopical study of a case of atypical cerebral lipidosis

Summary Histological and electron microscopical findings in a cerebral biopsy from a 16 year old boy are presented. He developed dementia from the age of 10 and grand mal from the age of 13. The histological picture was one of neuronal lipid storage disease, and the electron microscopy, while confirming this, was not clearly characteristic of any of the previously reported lipidoses. Apart from a few zebra bodies (characteristics of gargoylism) the neurons contained masses of material (here called granular vesicles) which resembled the pericyte deposits of gargoylism, though these are very rare in the neurones of that disease. It was therefore not possible to assign a presumptive classification to this case, as there was no clinical evidence of gargoylism.

Zusammenfassung Histologische und elektronenoptische Befunde einer Hirnbiopsie eines 16jährigen Knaben werden mitgeteilt. Klinisch bot er eine progressive Demenz seit dem 10. sowie Grand Mal-Anfälle ab dem 13. Lebensjahr. Histologisch ergab sich das Bild einer neuronalen Lipoidspeichererkrankung. Elektronenoptisch wurde dieser Befund zwar bestätigt, doch ergaben sich keine für die bisher berichteten Formen von Lipoidspeichererkrankung charakteristische Veränderungen. Außer wenigen Zebrakörpern (Merkmale des Gargoylismus) enthielten die Neurone massenhaft Material (als granuläre Vesikeln bezeichnet), das an die Deposite in den Perizyten bei Gargoylismus erinnert, obwohl sie äußerst selten bei dieser Erkrankung in den Neuronen angetroffen werden. Da klinisch keine Hinweise auf einen Gargoylismus bestanden, war eine eindeutige Klassifizierung dieses Falles nicht möglich.

     

A comparative immunohistochemical study on striatal Met-enkephalin expression in Alzheimer's disease and in progressive supranuclear palsy

Summary Using a sensitive immunoperoxidase technique we examined Met-enkephalin (MEnk) expression in the striatum and globus pallidus external segment (GPe) from patients with Alzheimer's disease (AD) and with progressive supranuclear palsy (PSP). In AD patients strong MEnk-like immunoreactivity was persistent in the striatum showing so-called striosomes. In addition, a number of typical woolly fibers were observed in the GPe. MEnk-positive striosomes were also visible in the striatum of PSP patients and were similar to those of normal controls and of AD patients. However, the MEnk-positive woolly fibers appcarance was less well recognizable in the GPe from all the PSP patients examined.     

Analytic work with LSD 25

Summary In this paper, work with LSD 25 as an aid to analysis has been described. Of particular interest, has been theseeming unpredict-ability and arbitrariness of experiences elicited by the drug, and an attempt has been made at finding the determining factor in emerging material. This appears to be the selection of complementary and compensatory unconscious contents; selected in accordance with Jung's idea of the psyche as a self-regulating system, striving toward wholeness.Clinical material has been grouped in five categories, in which different aspects of complementation are illustrated. Some questions of transference and resistance in connection with LSD treatment have been discussed; and ideas about typical mechanisms in certain categories of neuroses, as suggested by the patient's response to the drug, have been put forward.This report is based on a paper read at a meeting of the (British) Society of Analytical Psychology in 1957.     

Immunohistological,microscopical and neurochemical studies on encephalitides

Summary Histochemical and immunohistological studies were carried out with brain cell cultures derived from two patients with subacute sclerosing panencephalitis (SSPE). Morphologically the cultures showed polygonal, probably histiocytic, cell formations and spindle intranuclear inclusion bodies. An increase in intracellular proteins and ribonucleoprotein was demonstrated by histochemical techniques. Fluorescent microscopy revealed an antigen that reacted with measles-specific immunoglobulin in the spindle cells, in the multinucleated giant cells, and in some of the polygonal cells. The findings described resemble the histochemical and immunohistological cell changes in brains of SSPE patients.This investigation was supported by the Deutsche Forschungsgemeinschaft (AZ: Me 270/4), the Stiftung Volkswagenwerk and the Forschungsmitteln des Landes Niedersachen, and also, in part, by the U.S. Public Health Service Research Grant No. R01-06859 to the Wistar Institute from the National Institute of Neurological Diseases and Stroke.
