JOURNAL FREE ACCESSA forty-kilodalton (40-kDa) protein was extracted from alveolar bone of young adult rabbit with 0.5 M EDTA after extraction with 4 M GuHCl, and purified by gel-filtration, anion-exchange and hydroxyapatite columns using a high-pressure liquid chromatography system under denaturing conditions.
The purified 40-kDa protein was not susceptible to bacterial collagenase and thrombin, but was cleaved by cyanogen bromide. The protein was stained blue with Stains-all. Among various lectins, concanavalin A and lentil lectin agglutinin bound to this protein, but peanut agglutinin, Ricinus communis agglutinin, phytohemagglutinin-E and wheatgerm lectin agglutinin did not. Lectin binding assays showed that the protein is a glycoprotein containing large amounts of mannose and/or glucose residues, but is not a fragment of proteoglycan. The amino acid composition of the protein shows a characteristically high content of acidic amino acids. Therefore, the mineral-binding 40-kDa glycoprotein is considered to be osteonectin/secreted protein acidic and rich in cysteine (SPARC), in terms of similarities to bovine and porcine osteonectins with regard to molecular weight and contents of glycoses and amino acids.View full abstractDownload PDF (1638K) -

JOURNAL FREE ACCESSVarious clinical and immunological parameters were determined in patients with RA and patients with adult periodontitis. There were no significant differences between the two groups with regard to the number of missing teeth, although pocket depths and gingival inflammation scores were significantly increased in the periodontitis group (p <0.05). Salivary IgM levels were below the minimum detectable level in both groups, and no significant differences were evident between the two groups with regard to salivary IgG and IgA levels. However, serum IgG, IgA and IgM levels in RA patients were significantly higher than in periodontitis patients (p <0.05), indicating enhanced humoral immunity. The present findings suggest that RA patients are not a risk group for advanced periodontal problems in comparison with age- and sex-matched systemically healthy controls.View full abstractDownload PDF (680K) -

JOURNAL FREE ACCESSTwelve pleomorphic adenomas of minor salivary gland origin were examined for the distribution of S-100 protein, detected using the peroxidase-antiperoxidase (PAP) method. Strong S-100 protein immunoreactivity was noted in areas containing plasmacytoid cells, stellate and spindle cells against a myxochondroid or hyalinous stroma, and solid epithelial areas. Tubular and duct-like structures showed variable stainability. Stromal tissue and normal salivary glands were generally negative for S-100 protein. These findings were compared with those reported elsewhere.View full abstractDownload PDF (2327K) -

JOURNAL FREE ACCESSIn Japan, some dentists use indirect-exposure (screen) films for intraoral radiography, without the use of intensifying screens. The purpose of the present investigation was to determine whether film speed, inherent contrast, and latitude of Japanese indirect-exposure films used without intensifying screens were comparable to those of direct-exposure (non-screen) films used for intraoral radiography. The characteristic curves of Kodak Ektaspeed (“E” speed) and Ultra-speed (“D” speed) films were used as standards for comparison. Indirect-exposure films without intensifying screens were extremely slow compared with direct-exposure “E” and “D” speed films. Therefore, they should not be used for intraoral radiography because they needlessly expose the patient to excessive X-ray radiation. The direct-exposure films Hanshin Hi-Fi and Hanshin New Silver were equivalent in speed, higher in contrast, and narrower in latitude than Kodak Ektaspeed film. In general, the indirect-exposure films had lower speed, lower contrast and wider latitude than the direct-exposure films. Their speed and contrast would have been increased if intensifying screens had been used. Therefore, indirect-exposure films without intensifying screens should not be used for intraoral radiography.View full abstractDownload PDF (522K) -

JOURNAL FREE ACCESSThe finite element method is used to predict facial deformation following orthognathic surgery for mandibular prognathism. The deformation is calculated using a model that assumes severe skeletal class III malocclusion. The possibilities and limitations of this method for clinical application are described.View full abstractDownload PDF (1110K) -

JOURNAL FREE ACCESSEosinophilic granuloma is a disease of the reticuloendothelial system and its pathogenesis is not yet completely clear. The histopathological findings are granulomatous proliferation of histiocytes accompanied by diffuse infiltration of eosinophils.
We recently experienced a case of eosinophilic granuloma arising monostotically in the body of the mandible in the 76 region. There has been no local recurrence 17 months after surgical removal of the lesion.View full abstractDownload PDF (1894K) -

JOURNAL FREE ACCESSThe effect of crib therapy for the treatment of cases of open bite was investigated. Extrusion of the lower and upper incisors and intrusion of the lower first molars were the most significant effects of the appliance. Intrusion of the lower molars resulted in decreased lower facial height. These findings were considered to result from the posterior tongue posture. Thus, the clockwise pattern of the mandibular complex was changed to a counter-clockwise pattern.View full abstractDownload PDF (585K)
