    Multiple fractures of primary molars caused by injuries to the chin: report of two cases (2000)
    Copenhagen : Munksgaard International Publishers
    Dental traumatology 16 (2000), S. 0

    Notizen: Abstract – Two cases of multiple fractures of the primary molars caused by injuries to the chin are presented. Clinical and radiographic examinations revealed a vertical fracture line in the maxillary and mandibular primary molars. Pulpotomy or pulpectomy treatment was performed on the affected teeth, which were then restored with preformed stainless steel crowns.

    Effect of activin on cell growth in primary cultures of guinea pig gastric epithelial cells (2000)
    Oxford, UK : Blackwell Science Ltd
    Alimentary pharmacology & therapeutics 14 (2000), S. 0

    Notizen: Background: The effect of activin on differentiated cells is known to be different from that on undifferentiated cells. Cultured gastric epithelial cells in complete serum-free conditions grew into matured mucous cells after treatment with epidermal growth factor (EGF). Aim: To elucidate the effect of activin on the growth of differentiated and undifferentiated gastric mucosal cells. Methods: Cultured guinea pig gastric epithelial cells were prepared using the method of Ogihara et al. 1Synthesis of activin was analysed by Western blot using monoclonal anti-activin A antibody. Cell proliferation was assessed by counting the number of cells. Mucin production was assessed by histochemical study using periodic acid-Schiff (PAS) reaction. Results: Western blot analysis indicated that activin was synthesized in cultured guinea pig gastric mucosal cells. One hundred nanomolar EGF induced a 3-fold increase in cell count and the appearance of PAS-positive granules. Five nanograms activin per millilitre without EGF stimulated proliferation of the cells that showed almost negative PAS staining. When activin was added after treatment with 100 n m EGF for 24 h, cell proliferation induced by EGF was inhibited by activin at concentrations higher than 5 ng/mL. Conclusion: These results suggest that activin stimulates proliferation of undifferentiated cells and inhibits growth of differentiated cells.

    Coexisting clear cell adenocarcinoma and squamous cell carcinoma arising from ovarian endometriosis (2000)

    Notizen: Abstract A case of clear cell adenocarcinoma and squamous cell carcinoma coexisting in the ovary is presented. These two malignancies were adjacent but were not admixed, and ovarian endometriosis was confirmed concurrently. The clear cell adenocarcinoma was contiguous to monolayered glandular cells with cytological and architectural atypia, while squamous metaplasia with cellular atypia was observed adjacent to the squamous cell carcinoma. We concluded that these two malignancies arose independently from ovarian endometriosis. To our knowledge, this is the first report of such a case.
