    Notes: Abstract Treatment of demineralized dentin with hyaluronidase seems to increase exposure of collagen fibrils. The present study compared the in vivo connective-tissue response to dentin treated with citric acid alone and with citric acid plus hyaluronidase. Dentin specimens were obtained from areas beneath attached periodontal ligament fibers on extracted human teeth. Each rectangular specimen had a face of root surface dentin and an opposite surface composed of pulpal dentin. One group was treated with citric acid alone (A); a second group with both citric acid and hyaluronidase (AH); and a third group served as untreated controls (C). Specimens were examined in the scanning electron microscope (SEM) for morphologic characteristics, and used in an implantation model to evaluate cell, connective-tissue and epithelial responses. In the latter procedures, specimens were implanted transcutaneously into incisional wounds on the dorsal surfaces of rats. Four specimens in each group were evaluated 10 days after implantation and analyzed using histologic and histometric methods.SEM examination showed that the surface of the control specimens had a smear layer which concealed the openings of dentinal tubules. Dentinal tubule orifices were present on the surface of A and AH specimens. Enhanced exposure of the collagen fibrils was apparent on AH surfaces. The histologic and histometric analyses of A and AH groups showed that cell adhesion and fiber density did not differ between root and pulpal surfaces, or between A and AH-treated implants. However, a significantly greater number of cells were attached to A and AH surfaces than controls. In addition, fiber attachment was not present in the control group. A distinct eosinophilic surface zone was present on A and AH surfaces, which was significantly wider on pulpal surfaces and in AH specimens. The connective-tissue attachment that occurred in A and AH groups inhibited epithelial down-growth. The length of implant surface exhibiting connective-tissue attachment was significantly greater in AH specimens. It appeared that hyaluronidase treatment of the exposed collagen had increased the area of connective-tissue attachment to the implant surface.

    Notes: Abstract Objective: To describe the pattern of polypharmacy (PP) among older men and to relate medication use to personal, social and medical information. Methods: Information on medication use, both prescribed and `over the counter' (OTC), was collected from 1906 men, aged 56–75 years, observed on up to four occasions since 1979 in a community survey – the Caerphilly prospective study. On each visit, a variety of questionnaires regarding personal, social and medical factors were completed, and a brief medical examination was conducted. Medication use was related to some of the questionnaire information and biological measurements collected in order to identify factors associated with PP. Results: A quarter of the men (475/1906) reported using three or more prescription-only medicines (PoMs), with 9% (163) using five or more (major PP). PP was related to increasing age, lower social class, not being in employment, smoking and obesity (high body mass index). Men with a medical history, especially of high blood pressure, angina, heart attack, or hospital admission in the last 5 years, comprised a large proportion of those on major PP. Higher levels of PoM use by this group had been apparent over the previous 14 years. Men on PP reported lower levels of self-rated health and higher rates of non-PoM use. Cardiovascular and, to a lesser extent, central nervous and respiratory system drugs were the main medicines used by men on major PP. Conclusions: PP is common among men aged 56–75 years in Caerphilly, South Wales. It is related to many personal, social and medical factors, and associated with lower self-rated health status and greater use of non-PoMs. Cardiovascular medicines are the main contributor to major PP. Those on PP require regular review and, where possible, PP should be reduced as it has many potential adverse effects.

    Notes: Abstract Bone sialoprotein (BSP) is synthesized and secreted by bone-, dentine- and cementum-forming cells and has been implicated in de novo bone formation and mineralization. In this study, we used histological sections of odontogenic neoplasms and performed immunohi stochemical and in situ hybridization analyses. In ameloblastoma, BSP mRNA signals were seen in the neoplastic epithelial cells forming nests, strips and islands. BSP deposition was also seen in the stellate reticulum of the tumour masses revealed by immunohistochemistry using human BSP antibodies. In calcifying epithelial odontogenic tumour, the calcified masses demonstrated positive immunoreactivity to the human BSP antibodies, and the hybridization signals for BSP were located in the cells near the calcified particles. In the calcifying odontogenic cyst, strong BSP signals were seen in cells surrounding the characteristic nests of ghost cells, which often calcify subsequently. BSP protein was also found in these cells by immunohistochemistry. The active expression of BSP in the epithelial elements of the odontogenic tumours of adult patients suggests the activation of this matrix protein gene in the neoplastic process, and that BSP may play an important role in tumour formation and differentiation with respect to pathological calcification. © Chapman & Hall
