    Congenital cerebellar neuroepithelial tumor with multiple divergent differentiations (1980)
    Springer
    Acta neuropathologica 50 (1980), S. 143-146

    ISSN: 1432-0533

    Notes: Summary A case of congenital cerebellar tumor is reported. The tumor is composed of a few incomplete tubular structures analogous to the neural tube, and of neuroblastic, mature ganglionic, astrocytic, ependymal and undetermined neuroepithelial cells. A tentative diagnosis of congenital cerebellar neuroepithelial tumor with multiple divergent differentiations is made: the histogenesis is discussed. From a histogenetic point of view this tumor is given the provisional name of matrix cell tumor.

    Responsiveness of inferotemporal single units to visual pattern stimuli in monkeys performing discrimination (1980)
    Springer
    Experimental brain research 38 (1980), S. 313-319

    Notes: Summary Four monkeys were trained to choose two rewarded stimuli from four two-dimensional patterns presented successively, and the responsiveness of single units to these patterns was investigated. Eighty-three of 214 units (39%) recorded from the dorsolateral portion of the inferotemporal cortex were responsive; nearly half responded to all four patterns, irrespective of pattern shape and of whether the stimuli were rewarded or not. A few units were responsive to only one of the patterns, regardless of size, color, or luminance, and unresponsiveness to components of the response-eliciting patterns was indicated in some of these units. The activity of most units responsive to two or three patterns was dependent on pattern shapes rather than the learnt meaning of the patterns.

    Correlation between CT findings and subsequent development of cerebral infarction due to vasospasm in subarachnoid haemorrhage (1980)

    Notes: Summary We have studied the correlations between computed tomograms (CT), clinical severity at the time of onset, and subsequent development of cerebral infarction due to vasospasm in 32 cases with subarachnoid haemorrhage secondary to rupture of cerebral aneurysms. It was found that the clinical severity could be judged by CT as shown by the amount of blood in subarachnoid space. Furthermore, it was possible to predict the subsequent occurrence of cerebral infarction by sequential findings of CT. A Hounsfield number of the high density area over 60 showed good correlation with the development of cerebral infarction.

    VERAPAMIL-INDUCED CONTRACTURE IN AN EXCISED, BLOOD-PERFUSED SKELETAL MUSCLE PREPARATION FROM THE DOG (1983)
    Oxford, UK : Blackwell Publishing Ltd
    Clinical and experimental pharmacology and physiology 10 (1983), S. 0

    Notes: 1. The ability of verapamil to induce a contractile response in skeletal muscle was investigated using the canine isolated, blood-perfused diaphragm preparation.2. Verapamil-induced contracture was characterized by a biphasic increase in muscle tension consisting of an initial phasic and subsequent tonic contracture.3. The second tonic component of the verapamil-induced contracture was inhibited by procaine, but procaine had no effect on the initial phasic contracture.4. Verapamil potentiated both KCl- and caffeine-induced contractures during the second tonic stage. This action might be explained by enhancement by the drug of availability, or by an increased sensitivity of the contractile machinery to calcium liberated by membrane depolarization or by the calcium-induced calcium release mechanism.5. The second tonic component of verapamil-induced contracture was much less than the initial phasic component. It seems, therefore, that the calcium release induced by the procaine-resistant process is the principal action of verapamil in inducing contracture in skeletal muscle.

    The para-carotid approach for internal jugular catheterization (1981)
    Oxford, UK : Blackwell Publishing Ltd

    Notes: We have deqeloped a para-carotid approach for internal jugular cannulation which utlizes only the carotid artery as a landmark. This technique allows us to locatedhe puncture site regardless of an individual patient's physical, skeletal or postural variations. This study was undertaken in the period from January 1979 to June 1980 on 456 consecutive patients in a wide range of age groups and various clinical conditions. The overall success rate was 96.1%. The only complications encountered during our study were Five carotid artery punctures with formation of two haematomas.

    Further observations on the morphogenesis of human rotavirus in MA 104 cells (1984)
    Springer
    Archives of virology 79 (1984), S. 147-159 
    Details
    ISSN: 1432-8798
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Human rotavirus “KUN” strain was cultivated in a fetal rhesus monkey kidney cell line, MA 104 cells. Four types of virus particles in cells infected with KUN strain were clearly identified: nucleoid cores, single-shelled particles, double-shelled particles, and membrane band, “enveloped” particles. “Enveloped” particles were found only in the thin sections of infected cells. When first visible, the virus precursors appeared at the ribosome free membrane of rough endoplasmic reticulum (RER), increasing in size while simultaneously being coated with nucleocapsid, inner shell. Single-shelled particles were also synthesized within bundles of filaments of viroplasm in the cytoplasma. During subsequent virus maturation two types of “budding” processes were observed. Double-shelled particles arising at the RER membrane entered the cisternae of the RER through an exocytosis-like process. In contrast, the “enveloped” particles developed in the cisternae by being completely enclosed with RER membrane, and later during cytolysis released the single-shelled particles. These “enveloped” virus particles appeared to be the result of inefficient virus maturation at the last stage of outer capsid formation.
