| the action of ethanol upon the action potential and contraction of ventricular muscle. | isolated isometric ventricular muscle of frogs and cats was studied. perfusing solutions were played directly on the muscle to permit rapid exchange of the extracellular space. developed force and maximal rate of rise of force were measured in all studies and action potentials (ap) were recorded in some. for both species low concentrations of ethanol (75 degrees mg/l) potentiate contraction. higher concentrations ( greater than or equal to 750 mg/l) depress contraction progressively with increa ... | 1975 | 1081255 |
| [the acute vestibular paralysis (author's transl)]. | acute vestibular paralysis may not be considered as a nosologic entity but as a syndrome. symptomatology (vertigo, spontaneous and provoked vestibular nystagmus, absence of cochlear signs) shows an uniform picture. the results of the caloric test as well as the nystagmic responses induced by galvanic stimulation and the development of central vestibular compensation however indicate that the site of the lesion is not only confined to the labyrinth but may also occur at the level of the periphera ... | 1975 | 1081389 |
| treatment of spontaneous leukemia in akr mice with chemotherapy, immunotherapy, or interferon. | akr mice are genetically destined to develop gross (rna) virus-induced lymphatic leukemia. leukemic akr mice treated with combination vincristine, cyclophosphamide (cytoxan), and 1-(2-chloroethyl)-3-(trans-4-methylcyclohexyl)-1-nitrosourea sustained a 180% increase of life-span. combination chemotherapy plus immunization with neuraminidase-treated allogeneic (gross virus-induced) g2g leukemic cells intradermally resulted in 35% of animals surviving beyond 150 days without evidence of the disease ... | 1976 | 1082796 |

| hapten specific ige antibody responses in mice. v. differential resistance of ige and igg b lymphocytes to x-irradiation. | the studies presented in this paper were undertaken to determine whether ige- and igg-producing murine b lymphocytes could be distinguished by differential resistance to x-irradiation in vivo. sensitivity or resistance of b lymphocytes to various doses of x-irradiation was monitored by measuring the production by irradiated cells of hapten-specific igg and ige antibody. the results indicate that both primed and unprimed igg b lymphocytes are less radioresistant than corresponding ige b lymphocyt ... | 1976 | 1087320 |
| nystagmic modulation of neuronal activity in rabbit cerebellar flocculus. | 1. the responses of neuronal elements in the flocculus of the awake, restrained rabbit were recorded during horizontal vestibular nystagmus in the dark. 2. purkinje cells showed both vestibular (types i and ii) and eye movement modulation of simple spike activity. type i purkinje cells most commonly were inhibited in association with the ipsilaterally directed fast phase of nystagmus and excited during contralaterally directed fast phases. type ii purkinje cells had a similar modulation but in t ... | 1976 | 1087403 |

| yersinia enterocolitica : a review of its role in food hygiene. | since yersinia enterocolitica, now classified as a member of the enterobacteriaceae, was recognized as a distinct species in 1964 it has been isolated with increasing frequency from man and animals (including dogs and pigs) and from some human foods. y. enterocolitica infections are now seen as a cause for some concern in both human and veterinary medicine. the organism is commonly found in specimens from swine slaughterhouses and has been isolated from samples of market meat, vacuum-packed beef ... | 1976 | 1087589 |

| restriction of dna in yersinia enterocolitica detected by recipient ability for a derepressed r factor from escherichia coli. | a derepressed r factor, ry2drd2, was transferred at a frequency of 5x10minus 3 between two strains of yersinia enterocolitica mated on a membrane. under the same conditions transfer of this r factor from escherichia coli to y. enterocolitica was observed at a frequency of only 7-7x10minus 6. this frequency was greatly increased when the recipient strain was heat-treated before mating. heat exposure for optimum fertility was 50 to 52 degrees c for a period of 2 to 3 min. mutants of y. enterocolit ... | 1975 | 1095683 |
