Between Loagaeth and Cosening: Towards an Etiology of John Dee's Spirit Diaries Entre Loagaeth et Cosening: Vers une étiologie des Journaux spirites de John Dee
Authors: Sledge James Justin 
Published: March 2010

AbstractBien que le contenu de ce qu'on appelle les "journaux spirites" du Dr. John Dee (1527–1608/9) et de son "skryer" Edward Kelly (1555–1597?) ait fait l'objet de maintes interprétations savantes, une théorie étiologique systématique des séances elles-mêmes fait encore défaut. Après une évaluation et une critique des theories étiologiques données jusqu'ici, et spécialement de la "théorie charlatan", cet article entreprend d'établir une méthodologie critique centrée sur des facteurs explicatifs de mise entre parenthèse, puis de construire un modèle explicatif comprenant quatre éléments de base: 1) Les conditions environnementales dans les quelles les séances se situaient culturellement et matériellement. 2) Les traits comportementaux de Kelly qui dénoteraient la possibilité d'un état psychotique préexistant. 3) Des états modifiés de conscience (EMC) déclenchés par les séances elles-mêmes et venant, en plus, agir sur celles-ci. Et finalement: 4) Le processus épistémologique formateur qui permettait à Kelly de créer les contenus des séances comme une sorte de fabrication de mythe et comme quelque chose qui est à l'opposé de la tromperie délibérée. Cet article, qui s'appuie très largement sur les rapports que Dee tenait des séances, a pour objet de rendre compte, de façon substantielle, de l'étiologie des "conférences angéliques" elles-mêmes.
God's Last, Best Gift to Mankind: Gnostic Science and the Eschaton in the Vision of John Murray Spear Le dernier, le meilleur, cadeau à l'humanité: Science Gnostique et Eschaton dans la vision de John Murray Spear
Authors: Laycock Joseph 
Published: March 2010

AbstractEn 1853, John Murray Spear tenta de construire une machine en se servant de schémas reçus par communication spirite avec Benjamin Franklin. Les historiens se sont efforcés d'accorder cet épisode, connu comme 'l'Expérience du Nouveau Moteur', avec l'œuvre antérieure de Spear abolitionniste. On ne peut comprendre convenablement le Nouveau Moteur sans prendre en considération la place de la technologie dans le projet 'dispensationnaliste' de Spear. Si l'expérience avait réussi, les successeurs de Spear auraient cru qu'une source énergétique libre allait faciliter l'abolitionnisme ainsi qu'un paradis socialiste sur terre. Le Nouveau Moteur représente aussi une importante étude de cas en matière de théorisation des rapports entre ésotérisme et science. La vision qu'avait Spear d'un avenir utopique fonctionnant par la vertu d'une technologie spirituelle représente une forme de la 'science gnostique' qui s'est trouvée au carrefour des imaginations scientifique et religieuse.
Solve et Coagula: Attitudes Toward the Ambrosial Aspects of Human Seed in Certain Yogic Traditions and in the Sexual Magick of Aleister Crowley Solve et Coagula: Attitudes envers les aspects ambroisiens de la semence humaine dans certaines traditions yogiques et dans la magie sexuelle d'Aleister Crowley
Authors: Djurdjevic Gordan 
Published: March 2010

AbstractCertaines traditions du yoga voient dans la semence mâle l'élixir potentiel d'immortalité. L'éjaculation du sperme, lequel devrait retourner à son lieu d'origine, la tête, est une perte de ce potentiel. Dans celle-ci, en effet, cette substance acquiert sa forme subtile par transformation, devenant ainsi l'élixir. La méthode consiste en une spiritualisation du matériel. Cela correspondrait au solve selon la terminologie alchimique.La magie sexuelle d'Aleister Crowley part d'un point de vue similaire, mais ici la méthode se trouve inversée, car la semence est éjectée et consommée. Le sperme matériel est sanctifié, et vu comme une théophanie. Le spirituel est matérialisé: coagula.L'objet de cet article est de comparer ces deux orientations et d'en explorer les implications, la question essentielle étant ici celle de la localisation du sacré; en effet, l'une reflète l'acosmisme des traditions indiennes, et l'autre la tendance, propre à la magie d'Aleister Crowley, de valoriser l'existence matérielle.
Die Bedeutung der Plasmazellen als Antikörperbildner
Authors: Trautwein G. 
Published: March 2010

During the last two decades, it has been shown by a great number of morphological, clinical, and experimental investigations that the humoral antibodies are formed by plasma cells. Plasma cells are immobile connective tissue cells which are formed in the medullary cords of lymph nodes, the red pulp of the spleen, the bone marrow, and in the adventitia of small blood vessels. The theory of the plasmacellular antibody formation is based on these clinical and experimental observations: (1) Correlation of hypergammaglobulinemia in the blood serum and proliferation of plasma cells in the tissue in various diseases of men and animals. (2) Correlation of antibody concentration in the blood serum and plasma cell proliferation in hyperimmunized experimental animals. (3) Demonstration of antibody formation in plasma cells by in vitro experiments and extraction of γ-globulin from plasma cells. (4) Detection of antibodies in plasma cells with the fluorescent antibody technique. Macrophages and lymphocytos also play a role in antibody formation. While it is the function of the macrophages to transform corpuscular antigen into soluble immunogenic antigen, the lymphocytes play the role of a co-factor. In newborns the thymus lymphocytes transmit substances which are necessary for the development and function of the antibody producing system. The complicated problems of globulin synthesis in the antibody producing cell are explained in the light of the genetic theory of antibody formation advanced by Ehrich.
Pulmonary Nocardiosis in the Rhesus Monkey Importance of Differentiation from Tuberculosis
Authors: Jonas Albert M. , Wyand D. Stuart 
Published: March 2010

Two cases of pulmonary nocardiosis occurred in the primate colony of the Yale University School of Medicine from 1961–1965. During this same period 22 monkeys were necropsied with tuberculosis. Pulmonary nocardiosis may be mistaken grossly and microscopically for tuberculosis. Although the gross appearance of the lungs in both diseases may be indistinguishable, there are important differential points. Pulmonary nocardiosis has the following features which tend to differentiate it from pulmonary tuberculosis: No tracheobronchial lymph node involvement, No extra-thoracic lesions, and Demonstration of typical organisms on direct smear.
The Fine Structure of the Bovine Wart
Authors: Fujimoto Yutaka , Olson Carl 
Published: March 2010

The fine structure of 5 naturally occurring and 4 experimentally produced cases of bovine cutaneous fibropapillomatosis was compared to that of normal bovine skin with both light and electron microscopy. Both degenerative and proliferative changes were found in the affected epithelial cells and fibroblasts. Virus-like particles (approximately 40 m μ) were first seen in the nuclei of degenerating fibroblasts and later in the epithelium. The number of virus-like particles was always small and they were associated with aggregates of chromatin. They were most numerous in the stratum granulosum. The degenerative changes were aggregation and margination of chromatin in the nucleus. In addition, epithelial cells had cytoplasmic vacuolization, loss of tonofibrils, focal necrobiosis, increased electron opaque globules and dilatation of intercellular spaces with changes of desmosomes. When these changes were marked the cells could be recognized as “pale cells” by light microscopy and usually occurred in groups. Viral multiplication appeared confined to these degenerating cells and no viral particles could be found in the proliferating cells. The proliferating epithelial cells were increased in size. These changes were progressive in the developing fibropapilloma and could be categorized into stages of fibroplasia, immature fibropapilloma, mature fibropapilloma and regression.
A Congenital Progressive Ovine Muscular Dystrophy
Authors: McGavin M. D. , Baynes I. D. 
Published: March 2010

A congenital progressive myopathy affecting 2% of a flock of Merino sheep involved most of the muscles of the pelvic and pectoral girdles. The vastus intermedius muscle was consistently affected; at 2 years of age 50% of its fibers were replaced by fat and at 5 years almost all. Lesions were bilaterally symmetrical. Usually all components of the quadriceps muscle were involved, but scattered affected fibers were found in most other appendicular muscles. The lesions in the quadriceps muscles resulted in inability to flex the femoro-tibial joint, with consequent difficulty in locomotion, which, under range conditions, resulted in death from inability to forage. Histologically, affected muscles had rounded fibers with central and peripheral sarcoplasmic masses. The fibers contained vesicular nuclei that usually formed rows of up to 15, but occasionally up to 50. In 6-week-old lambs, muscle fibers ranged in diameter from 15-100 μ. No lesion was detected in the peripheral or central nervous system.
Vergleichende Untersuchungen über das histochemische Verhalten amyloider, fibrinoider und hyaliner Ablagerungen in der Gefässwand verschiedener Säugetiere und Vögel. I. Proteine
Authors: Jakob W. , Krieg K. , Hilgenfeld M. 
Published: March 2010

Zusammenfassung In den untersuchten amyloiden, fibrinoiden und hyalinen Gefässwandablagerungen konnten in wechselnder Intensität primäre Aminogruppen, Sulfhydryl- und Disulfidgruppen sowie die Aminosäuren Tryptophan, Tyrosin und Arginin histochemisch dargestellt werden. Da Tryptophan, Tyrosin und Cystin/Cystein verhaltnismassig reichlich in den Plasmaproteinen vorkommen, ist anzunehmen, dass Bluteiweisskörper einen wesentlichen Bestandteil dieser Ablagerungen darstellen. Eine morphologische Unterscheidung des Amyloids, Fibrinoids und Hyalins kann auf Grund des qualitativ-histochemischen Nachweises dieser Aminosäuren nicht vorgenommen werden, weil sie in allen 3 Substraten vorkommen. ∗
Myocardial Sarcosporidiosis in the Camel
Authors: El-Etreby M. F. 
Published: March 2010

Thirty-four of 42 hearts from apparently normal camels were infested with sarcosporidia. Cysts were invariably found in the papillary muscle of the left ventricular wall; in 12 hearts they were in the right ventricular wall and in 1 heart in Purkinje fibers. None was found in the auricular muscles. An acute non-suppurative focal interstitial myocarditis occurred in association with the sarcocysts in 10 of the affected hearts. This reaction may be caused by a toxin from the cysts or it may be an allergic type of response in a previously sensitized host.
Canine Cutaneous Histiocytoma A Light and Electron Microscopic Study
Authors: Kelly D. F. 
Published: March 2010

Cutaneous histiocytomas from 4 dogs were examined by light and electron microscopy. A large (up to 10 μ in diameter) mononuclear cell with prominent filiform processes of the plasma membrane predominated. Its cytoplasm contained relatively small amounts of endoplasmic reticulum and mitochondria, only occasional lysosomes, fibrils, most obvious in the perinuclear region, and small amounts of cytoplasmic debris. Acid phosphatase was not detected. Fibroblasts and collagen formed a small part of the lesion, except at the junction with surrounding dermis, where fibers were plentiful. The morphologic features of the lesion are compatible with the suggestion that the predominant cell is of histiocytic type.
Epithelial Changes in Porcine Exudative Epidermitis An Ultrastructural Study
Authors: Obel Anna-Lisa , Nicander Lennart 
Published: March 2010

The normal fine structure of the epidermis in piglets is similar to that in other mammals. Ten cases of exudative epidermitis were studied in different stages. In acute cases a crust of parakcratotic cells was evident. The cells of the stratum intermedium and the outer layers of the stratum spinosum were swollen and vacuolated. Desmosomes and tonofibrils were reduced in size and number. The intercellular spaces were enlarged and contained an opaque material. In subacute and mild cases the lesions were less pronounced. The healing process was studied in one less severe, acute case. The observations arc interpreted as indicating a primary lesion in the Stratum granulosum and possibly in adjacent cells of the stratum spinosum. No evidence of a bacterial etiology was found. The observed changes are similar to those seen in viral disease of the skin.
Classification of Epithelial Canine Mammary Tumors in a Defined Population
Authors: Monlux A. W. , Roszel J. F. , MacVean D. W. , Palmer T. W. 
Published: March 2010

Ductal carcinomas accounted for nearly all metastases seen in epithelial canine mammary tumors submitted to the Tulsa Registry of Canine and Feline Neoplasms in a 4-year period from a defined canine population. Lobular and squamous cell carcinomas were the only other metastatic carcinomas seen. Early ductal carcinoma was used to indicate nonmetastatic ductal carcinoma with a favorable post-surgical prognosis. Benign epithelial tumors were categorized as adenoma, ductal papilloma and squamous cell papilloma. Progressive transformation of well defined adenomas and papillomas to carcinoma was not evident in histologic preparations. Squamous metaplasia was seen in many ductal papillomas and ductal carcinomas. Inclusion of pseudocartilage and pseudoosteoid and osteoid, cartilage and bone with ductal carcinomas, adenomas and ductal papillomas seemed related to secretions escaping from neoplastic epithelial cells into stroma or between proliferating tumor cells. There was proliferation and perhaps even neoplastic transformation of myoepithelial cells in some of these tumors. Changes in myoepithelium, however, appeared to be secondary to neoplastic transformation of epithelium. Bone and cartilage in these tumors were considered heterotopic with no neoplastic potential.
Über die Antigenität eines chemisch induzierten neurogenen Sarkoms der Ratte [Antigenicity of a chemically induced neurogenic rat sarcoma—author's trans]
Authors: Elling H. , Stavrou D. 
Published: March 2010

Antigenicity of a chemically induced neurogenic rat sarcoma A neurogenic sarcoma was induced in the plexus brachialis of a male Long-Evans rat by administration of N-methyl-N-nitrosourea in the drinking water. The tumor was established in vitro and designated 76LE-NS-369. Cells from tissue culture grew as tumors when isografted in young rats. 76LE-NS-369 cells did not react with antiserum directed against gliaspecific S-100 protein. We used the cultured cells as target cells, and found specific antibodies in the sera of tumor-bearing and immunized rats by indirect fluorescent antibody stain and a complement-dependent antibody-mediated microcytotoxicity assay. In immunization experiments, incubation of tumor cells with Vibrio cholerae neuraminidase yielded higher antibody titers than an antigen preparation with untreated cells. Incubation with neuraminidase enhanced the sensitivity of tumor cells to antibody and complement in vitro, whereas trypsinized cells showed complete loss of reactivity with autologous antisera. The specificity of antisera was tested by absorption with tumor, lyophilized rat whole body and rat nerve tissues.
Intestinal Atresia and Stenosis in Animals: A Report of 34 Cases
Authors: van der Gaag I. , Tibboel D. 
Published: March 2010

Intestinal atresia was found in 29 animals and stenosis in five. Atresia was found in the duodenum in one pup; in the jejunum in nine calves, two lambs and one piglet; in the ileum in one pup, one lamb and one piglet; and in the colon in one foal, seven calves, one lamb, one piglet and three kittens. Stenosis was found in the duodenum of a foal, in the jejunum in two calves and one pup, and in both the ileum and the colon of a kitten. One lamb showed ilial atresia as well as ileal stenosis. We classified the atresia as type I, membrane atresia (four cases); type 2, cord atresia (six cases); and type 3, blind-end atresia (19 cases). In the literature and our own study, atresia was found only in the small intestine in puppies, but in foals and kittens it was found only in the colon, Atresia of the colon is more common in animals than in man, but multiple atresia, frequent in man, is rare in animals.
Die Kaliumhydrogenphosphat-induzierte Nephropathie des Hundes. I. Pathogenese der Tubulusatrophiee [Potassium Hydrogen Phosphate Induced Nephropathy in the Dog. I. Pathogenesis of Tubular Atrophy—author's trans.]

Published: March 2010

A nephropathy with severe tubular atrophy was observed in Beagle dogs after oral administration of K2HPO4 for 14 or 38 weeks. We describe the complete lysosomal degradation of atrophying tubular epithelial cells. During two experiments of 14 and 38 weeks duration, respectively, a total of 15 Beagle dogs received 0.8 g K2HPO4/kg body weight daily with their food. All dogs were examined clinically at regular intervals. Renal biopsies were taken in the fourth week from beagles of the 14-week study. Results were compared with those of control dogs. At the end of the experiments the animals were killed and necropsies done. Different stains and histochemical reactions were applied to paraffin sections of the kidneys. Acid phosphatase and β-glucuronidase were found on cryostat sections. Kidneys fixed by perfusion of five Beagles from the 38-week study and three Beagles of the 14-week study, and from five control dogs, were examined electron microscopically. Ultrahistochemically, acid phosphatase was demonstrated. Clinically, the dogs in both experiments vomited, were cachectic, and had elevated creatinine and blood urea nitrogen. Morphologically, qualitatively identical changes were seen, but the renal damage was most marked at 38 weeks. There were disseminated tubular atrophy (usually of the proximal tubules), focal scar tissue and nephrocalcinosis. The following pathogenesis was established for the lesions of the proximal tubule: Tubular atrophy begins with loss of differentiation of epithelial cells. Enzyme histochemistry, ultrahistochemistry and electron microscopy show an increase in autophagic vacuoles and autophagolysosomes. The lysosomal bodies showing fusion enclose large parts of the cytoplasm as the process continues. Complete lysosomal degradation of epithelial cells and extrusion of large lysosomes into the tubular lumen follow. After complete enzymatic digestion of the intratubular detritus, the residue is empty, convoluted and collapsed tubular basement membrane. Atrophic tubular epithelial cells have many organelle-free zones at their base, which contain fine filamentous material resembling that of the basement membrane. The degradation processes described here may explain why clinically the urinary sediment contains few cylinders and epithelial cells and why proteinuria decreases significantly toward the end of the experiment. So far, it is not clear whether the tubular basement membrane is synthesized by the tubular cells, by fibroblasts or by both cell types. The presence of basement membrane-like material in tubular epithelial cells and in parietal epithelial cells of the glomerulus favors the view that epithelial cells produce the basement membranes and that increased production of basement membrane-like material is a sign of loss of differentiation.
An Ultrastructural Study of Spinal Nerve Roots and Dorsal Root Ganglia in Aging Rats with Spontaneous Radiculoneuropathy
Authors: Mitsumori K. , Maita K. , Shirasu Y. 
Published: March 2010

The spinal nerve roots and dorsal ganglia of 104- to 135-week-old rats with spontaneous radiculoneuropathy were examined by light and electron microscopy. Demyelination was common in myelinated fibers of various diameters of both ventral and dorsal roots. The most striking alteration was wide distention of myelin sheaths, which extended throughout the entire internode. The spaces formed between separated lamellae frequently were invaded by macrophages. Subsequent vesicular degeneration of myelin seemed to be mediated by invading macrophages. These processes caused complete myelin destruction, but most axons showed no degenerative changes except for obvious reduction in diameter. Occasionally, there were clumping and partial degradation of neurofilaments and ruptured axolemma in the severely demyelinated axons. A few fibers also were undergoing wallerian-type degeneration, perhaps secondary to the severe demyelinative changes. Remyelinating fibers in various phases of repair were coexistent with markedly demyelinated ones. Demyelinative changes described above also developed within some of these remyelinated internodes. There were no remarkable changes in neurons of the dorsal root ganglia, though accumulation of lipofuscin was common. Our findings suggest that the changes in the nerve roots are essentially a primary segmental demyelination in aging rats with radiculoneuropathy.
The Subacute Neurotoxicity of Excess Pyridoxine HCl and Clioquinol (5-Chloro-7-Iodo-8-Hydroxyquinoline) in Beagle Dogs. II. Pathology
Authors: Hoover D. M. , Carlton W. W. 
Published: March 2010

The lesions caused by excess oral pyridoxine hydrochloride (150 mg/kg body weight/day) and clioquinol (200 mg/kg body weight/day), given individually and in combination to adult Beagle dogs, were evaluated. The experimental period was 100 to 112 days, except that four dogs in each of the clioquinol and combined-treatment groups were killed early because of severe debilitation or neurologic disease, and one dog given both compounds died on the third day of compound administration. Degenerative neurologic lesions had distribution specific for the compound given. Pyridoxine-treated dogs had lesions limited to tracts and nerves with neuronal bodies of their nerve fibers in the spinal and trigeminal ganglia. Clioquinol-treated dogs had neurologic lesions limited to the central nervous system. The most severe lesions were in the rostral dorsal funiculus and distal aspects of the optic nerve fibers, but minimal to mild degenerative changes also occurred in distal aspects of the corticospinal and spinocerebellar tracts. Dogs given both pyridoxine hydrochloride and clioquinol had a combination of the lesions in dogs given pyridoxine or clioquinol individually. Several dogs given clioquinol or pyridoxine plus clioquinol had extraneural lesions, including myocardial degeneration and thyroidal alterations.
Clinical Changes Caused by the Liver Fluke Metorchis conjunctus in Cats
Authors: Watson T. G. , Croll N. A. 
Published: March 2010

Cats infected with metacercariae of the fluke Metorchis conjunctus were followed clinically through their infection. Cats given 200 metacercariae showed few symptoms. All the cats passed ova on the 17th day. Three hundred metacercariae caused diarrhea, icterus, discolored urine, green feces and eosinophilia after 18 to 21 days. Eosinophilia, leucine aminopeptidase and alanine aminotransferase were elevated and remain the best indicators for metorchiasis. The hematological and serological abnormalities resolved rapidly and were absent from cats with chronic infection. Acute lesions (<32 days) were confined to the biliary trees with extensive epithelial exfoliation, fibrosis, and pus from necrosis, tissue feeding by the worms and pressure atrophy. Chronic infections (32 to 150 days) caused hyperplasia of the bile epithelium, proliferation of connective tissues, and fibrosis of the perilobular areas. Intense eosinophilic infiltrates were replaced by mononuclear cells. Granuloma formation around an ovum was seen in one cat 719 days after infection. Adult worms established preferentially in the left lateral lobe and never in the caudal lobe. No gall bladder involvement was found even in heavy infections.
