Excellent outcomes with angiographic subsegmentectomy in the treatment of typical hepatocellular carcinoma: a retrospective study of local recurrence and long-term survival rates in 120 patients with hepatocellular carcinoma.

Background: The authors successfully adopted an interesting and effective treatment for hepatocellular carcinoma (HCC) referred to as angiographic subsegmentectomy (AS). This treatment involved simultaneous embolization of the peripheral feeding artery and the portal vein. The result was that almost all of the HCC and peripheral liver parenchyma developed complete anatomic necrosis.

A study of attached and oriented human periodontal ligament cells to periodontally diseased cementum and dentin after demineralizing with neutral and low pH etching solution.

Background: This study aimed to evaluate quantitatively the migrated, attached, and oriented human periodontal ligament cells (HPLC) to periodontally diseased cementum and dentin after demineralization with low and neutral pH etching solution.

Methods: Human teeth, extracted due to periodontal diseases, were scaled and root planed so that cementum remained on one longitudinal half of the root and dentin was exposed on the other half. Forty root slices of 200 microm thickness, obtained from the mid-third of these roots, were divided into four groups: group 1, demineralized with a saturated solution of citric acid (pH 1.

[Clinical and histopathological observation of CaO-P2O5-MgO-SiO2-CaF system glass ceramic tooth implants in monkeys].

The present study was undertaken to determine the biocompatibility of a newly-developed CaO-P2O5-MgO-SiO2-CaF system glass ceramic tooth implant. Two adult male monkeys were selected and 12 weeks after extraction of M1 and P1, 8 glass ceramic teeth were implanted into alveolar bone. At 1 week after implantation, 6 teeth were allowed occlusal function, and 2 teeth were left free from occlusion as control teeth.

[Application of CaO-P2O5-MgO-SiO2-CaF system glass ceramics to periodontal therapy. Histopathological observation after implantation in furcation bony defect in monkeys].

This study was carried out in order to determine the efficacy of CaO-P2O5-MgO-SiO2-CaF system glass ceramics, which are made as implant materials, for treatment of furcation lesions. Glass ceramic granules were implanted in artificial class II furcation bony defects in monkeys. As controls, non-implanted sites were preserved.

Allergens of the house dust mite Dermatophagoides farinae--immunochemical studies of four allergenic fractions.

Analysis of the allergenic components of the house dust mite Dermatophagoides farinae was performed. Four different types of proteins reactive with human anti-mite IgE antibodies were identified as four distinct radioprecipitins in radioimmunoelectrophoresis. These were designated as mite allergen reactive with human IgE antibodies (Me) Me 1, Me 2, Me 3, and Me 4 according to their electrophoretic mobility from the slower to the faster.
