ジャーナル フリーExperiments were performed to determine if a pyrophosphate-containing anticalculus toothpaste could affect certain salivary constituents involved in the mineralization of dental plaque. The findings indicated no obvious changes in acid and alkaline pyrophosphatases, ionized calcium, total calcium, inorganic phosphate or pH in saliva for 1-135 min after brushing the teeth with the anticalculus toothpaste. Data obtained by brushing with the toothpaste three times daily for two weeks also confirmed these results. Our findings clearly indicate that pyrophosphate-stabilizing agents in the anticalculus toothpaste are not fully effective in the oral cavity. In addition, the pyrophosphate-containing toothpaste has no influence on the state of calcium and phosphate in saliva.抄録全体を表示PDF形式でダウンロード (785K) -

ジャーナル フリーAlong with clinical parameters, chemotaxis and random migration of neutrophils were evaluated in 15 patients with Down's syndrome (DS) and 15 healthy subjects. Signs of more severe gingival inflammation were present in the DS group. The random migration and chemotaxis of neutrophils were significantly decreased in comparison with the control group. In DS, the pathological status was attributed to these impaired host defense factors besides the existing bacterial plaque.抄録全体を表示PDF形式でダウンロード (639K) -

ジャーナル フリーA comparative study was made of two methods of cartilage preservation, 98% glycerol and 70% alcohol. Rib cartilage was treated by either of these methods and transplanted into the malar proccess of rats. Cartilage grafts preserved by both methods were equally well tolerated. Resorption and bone substitution were similar in both groups after 120 days, although resorption was greater for the alcohol-preserved cartilage up until day 30. The possible reduction in antigenicity by the 98% glycerol did not produce any difference of behavior from the cartilage preserved in 70% alcohol.抄録全体を表示PDF形式でダウンロード (2588K) -

ジャーナル フリーSeventeen cases of desmoplastic ameloblastoma were examined immunohistochemically. Immunoperoxidase techniques were applied for detection of keratin, desmin, vimentin and S-100 protein expression in these tumors. The tumor epithelium of desmoplastic ameloblastoma exhibited weak, focal, inconstant keratin staining, weak, variable expression of S-100 protein, desmin immunoreactivity of mild to moderate intensity and vimentin non-reactivity. The pertinent literature on the immunohistochemistry of ameloblastomas is briefly reviewed.抄録全体を表示PDF形式でダウンロード (1065K) -

ジャーナル フリーWe have developed a new assay method for collagenase activity, in the presence of two different types of collagenase inhibitors, in culture medium of periodontal ligament (PDL) cells. Human PDL cells were cultured with serum-free α-MEM for 5 days after reaching confluency, and the culture medium was then harvested. Collagenase and collagenase inhibitors in the medium were concentrated by ammonium sulfate precipitation. The precipitate was dissolved, and the suspension was applied to an Ultrogel AcA 54 column for partial purification. Collagenase inhibitor activity was detected as two peaks; a small inhibitor molecule of about 32 kDa sensitive only to dithiothreitol (DTT), and a large one of about 70 kDa considerably more sensitive to 4-aminophenylmercuric acetate (APMA) than to DTT. Therefore, pretreatment of the sample preparation with both DTT and APMA was necessary in order to inactivate the inhibitors prior to assay of latent collagenase. This observation indicates that PDL cells secrete collagenase and two collagenase inhibitors without any stimulation in vitro.抄録全体を表示PDF形式でダウンロード (1178K) -
Effects of Thickness and Stiffness on Changes Following Simulation of Orthognathic Surgery本吉 満, 吉住 昭彦, 中嶋 昭, 岸 正人, 納村 晉吉1993 年 35 巻 2 号 p. 118-123

ジャーナル フリーA study was conducted to investigate the influence of the thickness and stiffness of soft tissue on changes following orthognathic surgery. The finite element method was used to simulate surgery. Three finite element models with normal thickness and stiffness, twice the thickness and twice the stiffness were made in preparation for the simulation. The thickness of soft tissue had more effect than stiffness on posterior and vertical changes.抄録全体を表示PDF形式でダウンロード (693K) -

ジャーナル フリーA case of amelanotic melanoma arising in the upper molar region, which was difficult to diagnose histologically, is reported. The patient was a 79-year-old woman, who complained of a painful swelling in the gingiva of the left upper molar region. Routine histological examination showed that the lesion was composed of diffusely scattered atypical cells with round, spindle-shaped and irregular nuclei and scanty fibrous connective tissue. A fascicular arrangement was often found in the lesion, and no cancer nests were observed. Immunohistochemical study demonstrated positive staining for S-100 protein in both the nuclei and cytoplasm of the tumor cells. Electron microscopic examination revealed that cell organelles were abundant, and an interrupted basal lamina was often found along the cell membrane. The preliminary diagnosis was a non-epithelial malignant tumor.
After surgery, histological examination of metastases in lymph nodes from the submandibular region revealed that the tumor cells contained melanin pigment in the cytoplasm, as confirmed by Masson's melanin stain. The final pathological diagnosis was therefore amelanotic melanoma. Immunohistochemical staining for S-100 protein may be useful for differential diagnosis of amelanotic melanoma in conjunction with electron microscopic examination.抄録全体を表示PDF形式でダウンロード (2677K) -

ジャーナル フリーCongenital gingival granular cell tumor is a rare benign lesion of uncertain origin, which has been found only in newborn infants. This article describes one such case. Our immunohistochemical study employing antibodies against S-100 protein, epithelial membrane antigen, carcinoembryonic antigen, wide-spectrum keratin, desmin and vimentin yielded data supporting the theory of a mesenchymal cell origin for this lesion.抄録全体を表示PDF形式でダウンロード (1004K) -

ジャーナル フリーGranular cell ameloblastoma (GCA) is a well recognized variant of follicular ameloblastoma with extensive granular cell change. In contrast, plexiform granular cell odontogenic tumor (PGCOT) is a rare and recently described lesion characterized histologically by a monophasic plexiform pattern of granular cells. In this paper, two cases of an unusual granular cell odontogenic tumor exhibiting combined features of these two entities are described along with their immunohistochemical characteristics. The granular cells of both the GCA and PGCOT areas showed similar patterns of expression for keratin and S-100, which differed from those of typical ameloblastoma. No reactivity for desmin or vimentin was noted. The histomorphologic and immunohistochemical features of these hybrid tumors suggest that the granular cells present have a common origin, most probably the odontogenic epithelium.抄録全体を表示PDF形式でダウンロード (1498K)
