| characterization of mouse mammary tumor viruses propagated in heterologous cells. | mouse mammary tumor viruses (mmtv) from three different strains of mice have been used to establish productive infections in feline and mink cell lines. the virions that are released by these cells compete completely in a radioimmunoassay for the major virion surface glycoprotein of mmtv (gp52), thus demonstrating that antigenic determinants of gp52 are viral coded. competitive molecular hybridization studies have shown that the 60 to 70 s rna's of mmtv's propagated in feline cells contain all t ... | 1977 | 68813 |
| increased upper airway resistance to breathing during sleep in the cat. | at the onset of sleep, upper airway resistance shifted to higher levels which were maintained throughout sleep. with each inspiration, there was a decrease in upper airway resistance. these respiratory changes in resistance were smaller in wakefulness (on low baseline resistances) than those in nonrapid eye movement sleep (on high baseline resistances). in rapid eye movement sleep, modulations with inspiration were diminished and were intermittently absent, and baseline resistance was high. | 1977 | 68868 |

| effects of clozapine (leponex) on sleep patterns in the cat. | this study examined the effects of clozapine on sleep-wakefulness profile in cats prepared for chronic recording of sleep. clozapine in single dose (i.p.) of 5 mg/kg drastically reduced slow-wave sleep (sws) and paradoxical sleep (ps), while wakefulness and drowsy pattern were increased. these changes lasted approximately 24 h and were followed by sleep recovery. ps had a priority of recovery. some similarities between clozapine effects on sleep in cat and human were mentioned. | 1977 | 72523 |

| light-microscopical diagnosis of rabies. a reappraisal. | the validity of reports suggesting that lyssa and negri bodies are non-specific in the light-microscopical diagnosis of rabies was investigated. with seller's impression technique, a substantial proportion of speciments found to be non-rabid with the fluorescent-antibody technique showed structures indistinguishable from lyssa or negri bodies. neither histological examination nor inoculation of animals with non-rabid seller-positive material explained the nature of these rabies-like structures. ... | 1978 | 75337 |

| experimental horizontal transmission of feline leukemia viruses of subgroups a, b, and c. | experiments were conducted with cats in metal cages inside plastic isolators to determine whether feline leukemia virus (felv) of the three known antigenic subgroups (a, b, and c) is transmitted horizontally from infected cats to normal "contact" cats. blood smears collected at weekly intervals were examined by the fixed-cell, indirect immunofluorescence test for felv internal p30 to follow the spread of infection from inoculated cat to contact cats. these studies established that viruses of all ... | 1978 | 75981 |
| endogenous new world primate type c viruses isolated from owl monkey (aotus trivirgatus) kidney cell line. | a type c virus (omc-1) detected in a culture of owl monkey kidney cells resembled typical type c viruses morphologically, but was slightly larger than previously characterized mammalian type c viruses. omc-1 can be transmitted to bat lung cells and cat embryo fibroblasts. the virions band at a density of 1.16 g/ml in isopycnic sucrose density gradients and contain reverse transcriptase and a 60-65s rna genome composed of approximately 32s subunits. the reverse transcriptase is immunologically an ... | 1978 | 76312 |

| thalamic afferents to the limbic cortex in the cat studied with the method of retrograde axonal transport of horseradish peroxidase. | thalamic afferents to the limbic cortex in the cat were studied with the method of retrograde axonal transport of horseradish peroxidase. the anterior limbic region receives fibers largely from the anteromedial nucleus and partly from the anterodorsal and anteroventral nuclei. there appears to be a dorsoventral organization of cortical projections of the anteromedial nucleus to the anterior limbic region. the cingular area has its main input from the anteroventral and anteromedial nuclei. the lo ... | 1978 | 76501 |
| immunohistochemical study of a large molecular fragment of thyroglobulin in parafollicular cells. | thyroglobulin-like immunoreactivity of the parafollicular cells was studied by an immunoperoxidase bridge technique using antisera against dog thyroglobulin fragments. 1. the dog parafollicular cells were specifically stained by anti-peak i (27s and larger components fraction) antiserum absorbed with peak ii (19s fraction). by this method, they were easily distinguishable from the non-reactive follicular cells and colloid droplets. more sensitive staining of the parafollicular cells was possible ... | 1978 | 76516 |
| sleep patterns in cat induced by gammahydroxybutyric acid. | intravenous injections of gammahydroxybutyric acid (ghba) (150-200 mg/kg) induce desynchronized sleep (ds) in the cat. this was shown by recording the eeg, eye-movements, the neck emg, heart-rate and arterial pressure. the decreases in arterial pressure were not different from those recorded during naturally occurring ds. ghba, given at doses above 200 mg/kg induced anaesthesia, during which arterial pressure was elevated. at the end of ghba-induced sleep or anaesthesia there was a stage during ... | 1978 | 76561 |
| cerebellar afferent projections from the perihypoglossal nuclei: an experimental study with the method of retrograde axonal transport of horseradish peroxidase. | details of cerebellar afferent projections from the perihypoglossal nuclei were studied in the cat by means of retrograde axonal transport of horseradish peroxidase (hrp). labeled cells were observed bilaterally (with a preponderance ipsilaterally) in nuclei intercalatus and praepositus hypoglossi following injections in various folia of the entire vermis, paraflocculus, flocculus, fastigial nucleus, and the nucleus interpositus anterior and posterior. relatively high densities of labeled cells ... | 1978 | 76569 |
