the isolated human cortex. a golgi analysis of krabbe's disease.the clinical course of a child with krabbe's leukodystrophy was characterized by clinical seizures, startle myoclonus, and paroxysmal activity recorded by eeg. at autopsy in the fourth year, myelinated subcortical axons were destroyed, virtually completely. despite isolation from major subcortical and interhemispheric connections, the cell and fiber pattern of the cortex appeared remarkably normal in routine histologic preparations. the normal range of pyramidal and stellate interneurons were al ...197986346
inhibition of neuronal firing by opiates: evidence against the involvement of cyclic nucleotides.1. extracellular recordings were made in vitro from single neurones of the myenteric plexus of the guinea-pig ileum. 2. neuronal firing was inhibited by morphine and normorphine (10 nm to 1 micrometer). cyclic adenosine 3',5'-monophosphate (cyclic amp) (100 micrometer to 1 mm) also inhibited the firing of the majority of the neurones. prostaglandin e2 usually caused a short-lasting excitation of myenteric neurones and the phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine was usually withou ...197986371
double-stranded protamine cdna: synthesis and characterization.double-stranded protamine complementary dna (cdna) was synthesized from a protamine mrna template via the single-stranded cdna intermediate using avian myeloblastosis virus reverse transcriptase. synthesis at 37 and 46 degrees c resulted in similar overall yields (greater than or equal to 18%), although the initial rate of synthesis was higher at 46 degrees c than at 37 degrees c. the dna of the second strand of the double-stranded cdna product was 84% resistant to prolonged digestion with exces ...197986381
270-mhz nuclear-magnetic-resonance study on linear gramicidin a in dimethylsulfoxide. a new interpretation.on the basis of the finding of two sets of coupling constants (8.8 hz and 6.7 hz) in the 270-mhz proton magnetic resonance spectra of linear gramicidin in dimethylsulfoxide and the comparison of its infrared spectrum with those of known conformations of alternating poly(gamma-benzyl-d-glutamate--gamma-benzyl-l-glutamate), it is proposed that the antibiotic has an ld-ribbon structure.200086442

identification of polymorphonuclear leukocytes in cytologic samples for flow cytometry.inflammatory cells are commonly present in cytologic specimens obtained for flow cytometry, and may interfere with the analysis of epithelial cells. we have found that detergent (triton x-100) pretreatment in the two-step acridine orange staining procedure disrupts granulocyte cell membranes to yield bare nuclei; bladder epithelial and squamous cells on the other hand are quite resistant to the detergent treatment. being deprived of their cytoplasmic rna, the granulocytes lose red fluorescence. ...200086568
fluorescence polarization and pulse width analysis of chromosomes by a flow system.isolated chinese hamster chromosomes have been analyzed using a multiparameter computer-controlled cell sorter to obtain information about unique properties of individual chromosomes. parameters other than dna content were sought that would further aid in distinguishing among chromosomes. the polarized emission of the dna-specific bis-benzimidazole dye hoechst 33342 was measured for each class of chromosomes identified by a distinct peak, i.e., differeing in dna content. the emission anisotropy ...200086570
automatic cell identification and enrichment in lung cancer. i. light scatter and fluorescence parameters.two physical parameters were investigated to automatically recognize cells in sputum from human squamous cell carcinoma of the lung and to separate them for preparation by the papanicolaou methods, for human interactive identification and for automated high resolution image analysis. the two parameters, 0.5-15.0 degrees forward argon-ion laser light scatter to estimate total cell size and 546 nm acridine orange fluorescence to approximate total cell dna content, were measured in a flow-through f ...197986575
cytofluorometric and cytochemical comparisons of normal and abnormal human cells from the female genital tract.acridine orange staining of exfoliated cells from epithelial tissues facilitates discrimination between normal and abnormal cells: abnormal cells develop highly elevated nuclear fluorescence. comparisons of acridine orange (ao) staining with propidium iodide (pi) or feulgen staining have shown that: (a) pi staining also provides highly elevated nuclear fluorescence from abnormal cells; (b) the distributions of nuclear fluorescence following ao or pi staining were usually not significantly differ ...197986579
interactions between pairs of dna-specific fluorescent stains bound to mammalian cells.the interactions between dna-specific fluorescence stains complexed with mitotic chinese hamster cells were studied by spectrofluorometric and flow fluorometric techniques. the degree of binding interactions and of energy transfer between stains was determined from the intensities and shapes of fluorescence emission spectra of cells complexed with pairs of stains. the stain pairs hoechst 33258-chromomycin a3, hoechst 33258-ethidium bromide, and chromomycin a3-ethidium bromide exhibited efficient ...200086583

immune suppression in vivo with antigen-modified syngeneic cells. ii. t cell-mediated nonresponsiveness to fowl gamma-globulin.intravenous administration of syngeneic spleen cells coupled with the palmitoyl derivative of fowl gammma-globulin (p-f gamma g) results in a profound state of f gamma g-specific tolerance in c57bl/6 mice. administration of p-f gamma g coupled syngeneic cells specifically reduces both the primary and secondary hapten and carrier-specific pfc responses to tnp-f gamma g. since the haptenic response is affected, the tolerance functions at the level of the f gamma g-specific helper t cell. as few as ...197987447
evidence for shared idiotypy expressed by the igm, igg, and iga serum proteins of a patient with a complex multiple paraprotein disorder.the results of a comparative idiotypic analysis of multiple ig paraproteins isolated from the serum of an individual patient, ca, with sjögren's syndrome and waldenström's macroglobulinemia are reported. at initial presentation, ca serum was found to contain two major paraproteins, an igmkappa and an iggkappa, together with a small elevation in the level of iga protein. the patient's clinical course was characterized by dramatic and opposing changes in the respective serum levels of the igmkappa ...200087449
the action of strontium on basophil leukocytes and its use to probe the relationship between immunologic stimulus and secretory response.strontium will substitute for calcium in the activation of histamine secretion from human basophil leukocytes stimulated by an immunologic reaction or by the ionophore a23187. strontium is required in 10-fold higher concentration (1 to 10 mm) to activate histamine release compared with calcium (0.1 to 1.0 mm). in terms of maximum release obtainable for a particular immunologic stimulus, strontium is more effective than calcium. results are presented to show that calcium and strontium act at the ...197987471
pattern and flash visual evoked responses in multiple multiple sclerosis (ms), increase of delay may be important, but the earlier change is the behavior of the wave shape; amplitude is always lower even in ms patients without visual subjective symptomatology, provided not only flash but also pattern stimulation is performed. normal amplitude with pattern stimulation does not necessarily mean normal with flash. combining both stimulation methods, we obtained lowering of amplitude and change of wave shape in 100% of cases while latency was increa ...200087495
