ジャーナル フリーStudies have demonstrated significant heterogeneity in neutrophil granule morphology and physical density. Using cytochemical methods to localize peroxidase and vicinal glycol containing complex carbohydrates we examined the heterogeneity of neutrophil granules from intact human neutrophil granules in 13 isolated granule density fractions, calcium ionophore A23187 treated neutrophils and neutrophils from patients with Chediak-Higashi Syndrome and Specific Granule Deficiency. At least four distinct populations of peroxidase positive granules (PPG) were identified based on peroxidase staining, vicinal glycol staining, morphology, β-glucuronidase and defensin content, and physical density characteristics. The smallest (0.15 μm diameter) PPG was the least dense granule, had a unique peroxidase/β-glucu-ronidase ratio, reacted intensely for vicinal glycols, resisted ionophore degranulation and was not consumed in giant granule formation in Chediak-Higashi Syndrome. The largest (0.3 μM average diameter) and most physically dense PPG was rich in defensins, stained weakly for vicinal glycols, and was absent in specific granule deficiency. These studies demonstrate and correlate morphologic, biochemical, functional, and pathologic differences in PPG populations.抄録全体を表示PDF形式でダウンロード (4861K) -

ジャーナル フリーDifferent oral manifestations, the most prominent characteristics of the different oral symptoms, and oral colonization by Candida albicans were studied in 97 patients with leukemia and lymphoma. Oral manifestations usually occurred in both leukemias and lymphomas. The most common manifestation in both diseases was mucosal pallor. Oral colonization by Candida albicans in all patients was determined by the use of Sebouraud's agar plates and quantitative estimation of the colonization was made on a scale of +1 to +4 according to its presence in the four quadrants of the agar plates. Oral colonization by Candida albicans was between +1 and +4 in the patients with leukemia and was between +1 and +3 in the patients with lymphoma. Professional dental follow-up should be integrated into the medical followup. This is important not only for diagnosis of the disease, but also for prevention and treatment of complications during subsequent treatment.抄録全体を表示PDF形式でダウンロード (783K) -

ジャーナル フリーA study was conducted to evaluate the relationships between morphological characteristics of vertical sections of the mandibular body and dentopfacial morphology. Cortical bone thickness, tooth inclination and bone inclination of the mandible were investigated. Among skeletal components, ANS-Me distance was associated with the buccal cortical bone thickness of the P2 (second premolar) section. Gonial angle, SN to mandibular angle, and palatal to mandibular angle were negatively correlated with the buccal cortical bone thickness of P2 and MI (first molar) sections. SNA and SNB which indicated the protrusion of the upper and lower jaws were positively correlated with the buccal cortical bone thickness of the M1 section. Among denture components, lower and upper incisor positions showed a significant negative correlation with the buccal cortical bone thickness of the P2 section. The interincisal angle was associated with the basal cortical bone thickness of the M2 (second molar) section. In summary, there were significant and complex relationships between the structures of the mandibular body and maxillofacial morphology. Facial types which relate to masticatory function are associated with the cortical bone thickness of the mandibular body.抄録全体を表示PDF形式でダウンロード (903K) -

ジャーナル フリーA study was done to clarify the attachment position of the superficial masseter muscle and its relationship with craniofacial morphology in dentate and edentulous subjects. Data were obtained from lateral cephalometric radiographs of a total of 39 cadavers in which the superficial masseter muscle had been defined with colloidal barium. Principal component analysis provided evidence that the lower masseter muscle width was associated with the size of the ramus, and related to the position of the anterior margin of the muscle. Linear discriminant function data suggested that ramus width, coronoid height and the distance between the anterior margin of the masseter muscle and the mandibular notch contributed most to the observed difference between dentate and edentulous subjects. The derived function correctly assigned 100% of dentate and 95 % of edentulous subjects. The results of this study indicated that a reduction of masticatory function was associated with the position of the anterior border of the masseter muscle insertion and also with differences in ramus dimension, the most significant of which were differences in the coronoid process and gonial angle. In general, age was not a significant determinant of variation in superficial masseter muscle dimensions or orientation.抄録全体を表示PDF形式でダウンロード (1029K) -

ジャーナル フリーA case of a central tubercle on the lingual surface of the upper lateral incisor in a 61-year-old Japanese male is reported. The morphologic form of the central tubercle was similar to that of dens evaginatus frequently found in premolars. It was completely distinguishable from a talon cusp, which is a protrusion of the lingual cingulum. Radiographically, the present case was also complicated by dens invaginatus. We also review the Japanese literature on central tubercles of the incisal region.抄録全体を表示PDF形式でダウンロード (1425K)
