| kinetics of mucous cells in bronchial and bronchiolar epithelia during aerogenic elicitation with aspergillary proteins. a quantitative cytologic study. | during a prolonged exposure of rabbits to aerosols with asperigillary antigens, the content of bronchial and bronchiolar epithelia in mucus-secreting cells was quantified. in normals, the mucous cells do not exceed 3.2 per cent in bronchial epithelium and 0.44 per cent in bronchiolar one. after exposure, these proportions rapidly increase, after a primary discharge of goblet cells. the mucous cells become a majority after 7 exposures in bronchi and after 21 in bronchiolar epithelium. the maturat ... | 1975 | 129684 |

| enzymatic determination of nonrandom incorporation of 5-bromodeoxyuridine in rat dna. | secondary cultures of normal rat embryo cells were synchronized by a double thymidine block and pulsed with 10(-7) m 5-[3h]bromodeoxyuridine (brdurd) or 10(-7) m[3h]thymidine during an entire s phase (7.5 h). to examine the pattern of [3h]thymidine, dna was immediately extracted and purified at the completion of the s phase, cscl density gradient centrifugation revealed that substitution for thymine by bromouracil was less than 7%. single-strand specific nucleases obtained from aspergillus oryza ... | 1976 | 133713 |
| experimental data asserting the immune morpho-pathogenic component of chronic inflammatory processes. | the action of several agents (mycobacteria, aspergillus, silicium dioxide, beryllium salts, phospholipids, incomplete and complete freund adjuvant, a.o.) was analysed on the rabbit lung. the developmental analysis of experimental processes induced by intravenous or intratracheal injections showed that after a first inflammatory phase an immune one was formed, demonstrated by epithelioid cells, lymphocytes and plasma cells. in some cases, several waves of immune cells could be demonstrated in the ... | 1976 | 134277 |

| [otomycosis]. | from 163 patients with clinical diagnosis of otomycosis, only 72 were confirmed by the mycological laboratory. no difference was noticed regarding the age and sex of patients. the clinical symptoms were the break of the timpanic membrane, secretion and fungal colonies in one side. most of our patients had more than one year of evolution. the more common causative agent was aspergillus and quite frequently it were present non-pathogenic bacteria. the local treatment with a solution containing vio ... | 1976 | 141044 |

| enzymatic release of iron from sideramines in fungi. nadh:sideramine oxidoreductase in neurospora crassa. | young mycelia of the fungus neurospora crassa contain a soluble nadh-linked sideramine reductase, which may be responsible for liberating iron in vivo from accumulated sideramines during iron-deficient cultivation. the enzymes can be assayed using a soluble supernatant fraction, edta, and an atmosphere of pure nitrogen. the enzyme is stable without loss of activity up to 45 degrees c and has an optimum of activity at ph 7.0. besides coprogen (km = 100 micrometer, v=2.8 nmol/min per mg protein), ... | 1977 | 144535 |
| circulating immune complexes and activation of the complement sequence in acute allergic bronchopulmonary aspergillosis. | a 13-yr-old asthmatic girl with allergic bronchopulmonary aspergillosis (abpa) exhibited eosinophilia, ige hypergammaglobulinemia, serum precipitins to aspergillus, a dual skin reaction to aspergillus fumigatus, and positive, lymphocyte transformation in vitro in response to stimulation with aspergillus fumigatus antigen. the acute phase of the disease was characterized by an increase in blood eosinophilia, a rise in serum ige, circulating immune complexes, and evidence of activation of the comp ... | 1977 | 144747 |
| nuclear-extranuclear interactions affecting oligomycin resistance in aspergillus nidulans. | the extranuclear mitochondrial oligomycin-resistant mutation of aspergillus nidulans, (olia1), was transferred asexually into four nuclear oligomycin-resistant strains of different phenotypes. in all four cases, the possession of the nuclear plus extranuclear mutation led to an increase in the in vivo level of oligomycin resistance. in two cases, the altered cytochrome spectrum and impaired growth ability determined by (olia1) were suppressed by the nuclear mutations. in the third case, the in v ... | 1977 | 144864 |
