| modulation of human neutrophil adherence by oral bacteria. | polymorphonuclear neutrophils (pmns) comprise over 90 per cent of leukocytes in the oral cavity. although these phagocytic cells have primary defence roles in the gingiva, their stimulation by micro-organisms may also cause substantial tissue damage due to the release of lysosomal enzymes and oxygen radicals. adherence of pmns to the endothelium and their subsequent diapedesis and egress to areas of infection are considered early vital events in the inflammatory process. in this study, oral bact ... | 1992 | 1605750 |
| [polymorphonuclear leukocyte-mediated effects on human oral keratinocytes by periodontopathic bacterial extracts]. | in order to investigate the polymorphonuclear leukocyte-mediated oral keratinocyte injury, the author established a method to culture keratinocytes (scc9 and gingival keratinocytes) and subjected to the cell detachment assay by polymorphonuclear leukocytes and/or bacterial ultrasonic extracts from actinobacillus actinomycetemcomitans y4, bacteroides forsythus omz 408, fusobacterium nucleatum atcc 10953, capnocytophaga sputigena 4 and eikenella corrodens 1073. the bacterial extracts alone caused ... | 1992 | 1607829 |
| early effects of periodontal therapy on the detection frequency of four putative periodontal pathogens in adults. | this study aimed to examine early posttreatment changes in the periodontal microflora. paper point sampling and conventional bacterial cultivation were used to monitor the effects of surgical and non-surgical periodontal therapy on the detection frequency of porphyromonas gingivalis, prevotella intermedia, actinobacillus actinomycetemcomitans, and capnocytophaga species in deep periodontal pockets. ten patients, 5 men and 5 women (mean age 44 years), with advanced periodontal disease were select ... | 1992 | 1625154 |

| relation of baseline microbial parameters to future periodontal attachment loss. | the relationship between the level of subgingival species at baseline and subsequent attachment loss in a subject was examined. 38 subjects (14-71 years) with prior evidence of periodontal destruction were monitored 2x for pocket depth and attachment level at 6 sites per tooth at baseline and 2 months. a subject was considered to exhibit new attachment loss if 1 or more sites increased 3 mm or more in attachment level in 2 months. subgingival plaque samples were taken at the baseline visit from ... | 1991 | 1661304 |
| clinical and microbiological patterns of adults with periodontitis. | although current data suggest that periodontitis may actually be multiple diseases each with varying responses to therapy, little evidence exists to support this theory in adult patients. this report describes the design and initial findings of a longitudinal field trial involving the diagnosis and treatment of adult and refractory periodontitis patients in private practice. adult patients (n = 221) who met specific clinical criteria were selected from the private practices of 22 periodontists. ... | 1991 | 1663156 |
| in vitro killing of actinobacillus actinomycetemcomitans and capnocytophaga spp. by human neutrophil cathepsin g and elastase. | the purpose of this study was to compare the killing of actinobacillus actinomycetemcomitans with that of capnocytophaga spp. by purified cathepsin g and elastase in vitro. both were sensitive to killing by purified cathepsin g, but only the capnocytophaga spp. were killed by elastase. killing by cathepsin g exhibited logarithmic kinetics, was enhanced slightly by alkaline ph, and was enhanced greatly under hypotonic conditions. treatment of cathepsin g with diisopropyl fluorophosphate significa ... | 1991 | 1879926 |

| in vitro killing of oral capnocytophaga by granule fractions of human neutrophils is associated with cathepsin g activity. | the capnocytophaga are inhabitants of the hypoxic human gingival crevice that are normally prevented by neutrophils from causing periodontal and systemic infection. to identify potential nonoxidative bactericidal mechanisms against capnocytophaga within human neutrophils, gel filtration chromatography was used to fractionate neutrophil granule extracts. seven granule fractions, designated a through g, were obtained. the capnocytophaga were most sensitive to killing by fraction d. fraction d exhi ... | 1991 | 2022730 |
| capillary gas chromatography of cellular carbohydrates as a means for the differentiation of fastidious, slow-growing or anaerobic gram-negative bacteria--a review. | the phenotypic differentiation of microaerophilic or anaerobic gram-negative bacteria of human origin is traditionally based on the analysis of metabolic characteristics. due to outstanding growth requirements of many kinds of parasitic bacteria, e.g. of the facultatively and strictly anaerobic members of the human periodontal flora, conventional biochemical tests are time-consuming and sometimes lead to doubtful results. commercial diagnostic test kits often produce misidentifications because o ... | 1991 | 1755919 |
