    Notes: Summary Two cases of IgA pemphigus, one of the subcorneal pustular dermatosis (SPD) type and one of the intraepidermal neutrophilic IgA dermatosis (IEN) type, are described. IgA anti-keratinocyte cell surface antibodies reacted only with the uppermost epidermis in the SPD type but with the entire epidermis in the IEN type. A cDNA transfection test for desmocollins (Dsc) revealed that IgA antibodies of the SPD type reacted with Dsc1, but the IEN type did not react with any of the Dsc isoforms (Dsc1–3). ELISA for desmoglein 1 (Dsg1) and Dsg3 showed that neither of the cases had antibodies to Dsg − of either the IgG or IgA subtype. These results confirm that the autoantigen in SPD-type IgA pemphigus is Dsc1, whereas the antigen in most cases of IEN-type IgA pemphigus is unknown.

    Notes: Feeding experiments were conducted to determine the bioavailability of new types of manganese (Mn) supplement to rainbow trout fingerlings. Two levels of Mn (7 and 14 mg kg−1 diet) were supplemented to diets using either manganese sulphate (Mn-S), glass-embedded Mn (Mn-Gl), or amino acid-chelated Mn (Mn-Am); more than one acid was used to chelate the metal. Rainbow trout weighing 1.30 g on average were fed the experimental diets for 12 weeks. Absorption of Mn from various compounds was evaluated using larger fish (105 g on average) fed the experimental diets. Growth was higher in the group supplemented with Mn-Am at both levels. Whole-body Mn content in fish fed the diet supplemented with Mn-Am was significantly higher than the other sources. Bone Mn accumulation was significantly higher in treatments with 14 mg Mn kg−1 diet from all sources, except Mn-Gl. At 7 mg kg−1, absorption from Mn-Am was significantly higher than from Mn-Gl and Mn-S. Mn retention from both levels of Mn-Am supplementation was significantly higher (P 〈 0.05) than the rest. The results indicated that amino acid-chelated Mn provided more bioavailable nutrient than Mn-S and Mn-Gl. Further, availability of Mn from Mn-Gl is equivalent to that of Mn-S.

    Notes: Abstract: Three cases of adenomatoid odontogenic tumour (AOT) were examined by morphological and immunohistochemical methods, to define the nature of tumour cells and to determine the correlation between the occurrence of extracellular eosinophilic amorphous material and epithelial tumour cells. The epithelial tumour cell components observed in this study were divided into three cell types (cell type I: small compact cells in a solid nodule and pseudoglandular cells in a duct-like structure; cell type II: peripheral elongated cells and spindle-shaped cells in a cribriform pattern; and cell type III: metaplastic squamous cells). The mesenchymal components consisted of eosinophilic amorphous material and calcified material. Immunohistochemically, the type I cells reacted positively with antibodies to transferrin, ferritin and alpha-one-antitrypsin (α1-AT), whereas the type II cells constantly indicated intense expression only for transferrin and α1-AT. All types of epithelial tumour cells reacted negatively with lactoferrin, alpha-one-antichymotrypsin, S-100 protein, S-100α subunit and S-100β subunit. Moreover, the eosinophilic amorphous material and calcified material examined were positive for the antibody against α1-AT. These materials expressed immunophenotypes similar to those of the epithelial tumour cells, except for metaplastic squamous cells. The present study showed that iron-binding proteins and proteinase inhibitor might be related to the pathogenesis of AOT. Furthermore, we indicated that the formation of eosinophilic amorphous material was associated with type I and type II cells.

    Notes: The aim of this investigation was to evaluate the immunohistochemical distribution of vimentin in the temporomandibular joint (TMJ) and to compare it with the control specimens. Immunohistochemical distribution in the disc and synovial membrane in 30 human TMJ (internal derangement of TMJ, n = 20; and control, n = 10) was studied immunohistologically using paraffin-embedded tissue and specific anti-human vimentin monoclonal antibody. Vimentin expression was distributed in chondrocyte-like cells, synovial cells and endothelial cells. There was an obvious distinction of vimentin immunoreactivity between the control specimens and internal derangement cases, in the posterior and/or anterior loose connective tissues. In particular, intensive vimentin expression was detected in the hypertrophic synovial membrane of internal derangement cases. The findings of the present study suggest that vimentin might be an important marker of pathological hypertrophy of the synovial membrane and/or connective tissue with internal derangement of TMJ.

    Notes: The aetiology of temporomandibular joint (TMJ) disc displacement has been investigated using human post-mortem material. Twenty TMJ specimens were used for a histological procedure with haematoxylin and eosin staining and orceine staining. Immunohistological analysis with chondroitin-6-sulphate and keratan sulphate was also carried out on the same specimens. Immunohistochemically, the specific localization of chondroitin-6-sulphate and keratan sulphate in the antero-medial parts of the anteriorly displaced deformed TMJ disc, which may be load-bearing areas, was observed. Orcein staining revealed that specific elastic fibres pulling the anterior band and stretching the disc continuously, may be an important factor in disc displacement. On the basis of these results, we were able to propose a significant new hypothesis for the aetiology of disc displacement.

    Notes: Summary The expression of mRNA of tenascin in the temporomandibular joint (TMJ) disc and synovial membrane was examined in 20 human TMJ samples from patients with internal derangement of the TMJ and 10 control specimens by in situ hybridization technique using paraffine-embedded tissue, and antisense and sense cRNA probes. In control specimens, tenascin mRNA was not expressed. However, we were able to find tenascin mRNA expression in the surgical specimens. In 15 of 20 samples, ranging numbers of synovial cells expressed tenascin mRNA in the hypertrophic synovial membranes. Also, in 6 of 20 samples, tenascin mRNA was identified in fibroblasts. In four specimens, vascular endothelial cells were positive for the mRNA. In internal derangement cases, histopathological findings are often found such as synovitis, new capillary growth and fibrosis. The present study demonstrates that tenascin is produced specifically in synovial cells, vascular endothelial cells and fibroblasts affected in the portion of TMJ with internal derangement.

    Notes: summary  The aim of this investigation was to evaluate the immunohistochemical expression of cyclooxygenase-2 (COX-2) in the temporomandibular joint (TMJ) and to compare it with that control specimens. Expression of COX-2 in the TMJ disc and the synovial membrane in 26 human TMJ samples (internal derangement of TMJ; n=16, and control; n=10) was measured by an immunohistological technique using paraffin-embedded tissue and specific antihuman COX-2 polyclonal antibody. There were obvious distinction of COX-2 immunoreactivity between the control specimens and internal derangement cases, in the region of posterior and/or anterior loose connective tissues. In particular, intensive COX-2 expression was detected in the synovial membrane of internal derangement cases. The findings of the present study suggest that COX-2 might be an important mechanism regulating inflammation in the synovial membrane with internal derangement of TMJ.

    Notes: To grasp the documented evidences available regarding the cause of the anteriorly displaced human temporomandibular joint (TMJ) disc. With 20 specimens of human TMJ from cadavers, at first the number of heads of lateral pterygoid muscle (LPM) bundles were analysed with macroanatomical method. Secondary histological procedure with haematoxyline and eosine staining and orceine staining were carried out for the same specimens. Macroscopically, in 13 specimens an upper and a lower head of the LPM were present. In the other seven specimens, not only an upper and a lower head, but also a third inner head of the LPM covered with a separate fascia was observed. Histochemically, the specific localization of certain bundles of thick elastic fibres in the antero-medial parts of the anteriorly displaced deformed TMJ disc were observed.

    Notes: Cyclooxygenase-1,2 (COX-1,2) or prostaglandin (PG) H synthase, is the first enzyme of the pathway in which arachidonic acid is oxidized to PGs. Thus, we examined the expression of COX-1 in 16 human temporomandibular joint (TMJ) samples with internal derangement and in 10 control specimens by an immunohistological technique using paraffin-embedded tissue and specific antihuman COX-1 polyclonal antibody. There was obvious distinction of COX-1 immunoreactivity between the control specimens and internal derangement cases, at the endothelial cells and fibroblasts, in the region of posterior and/or anterior loose connective tissues and synovial membrane. The findings of the present study suggest that COX-1 might be an important mechanism for maintaining normal homeostasis at the endothelial cells and fibroblasts with internal derangement of TMJ.
