    Notes: Basal cell carcinomas arising from epidermal cysts are rare. A 76-year-old Japanese man had had a blackish nodule on his right knee for 15 years, under which he later noticed the development of a subcutaneous nodule. On histological examination masses of tumour cells showed the feature of adenoid and solid patterns of basal cell carcinoma that were connected to the wall of epidermal cysts in many places as well as with the overlying epidermis.

    Notes: summary  Recently, various authors have proposed the interesting idea that occlusal force may be a principal factor in cervical lesions of the tooth. It is speculated that the lateral force in non-ideal mastication causes the tooth to bend and that the resulting tensile stress damages the enamel surface. In this study, we carried out stress analysis on the upper central incisor and the lower first molar using the plastic–elastic deformation theory with two-dimensional finite element method (FEM). The essential feature that the tensile yield strength is much smaller than the compressive one was taken into account. Our results suggested that oblique loading on the tooth stretches the enamel surface near the cemento-enamel junction and causes plastic deformation which eventually leads to the cervical lesion.

    Notes: Juvenile flounder Paralichthys olivaceus were size-graded into three groups (small, large and mixing of small and large) and social interactions (feeding, aggressive attacking and activity) and growth of the fish were investigated. Growth of the subordinates (small flounder) was markedly suppressed by the presence of the dominants (large flounder). Dominants did not significantly suppress the overall food intake of the subordinates, but exhibited high aggressive attacking on the subordinates and consequently inhibited their activity. Size dominant interactions had little influence on the aggressive behaviour, feeding, activity and growth of the dominants. Results substantiated the hypothesis that the retardation in the growth of the subordinate flounder was attributed to the physiological costs of ‘stress’ by the aggression of the dominants. Individual differences in aggressive behaviour, feeding and activity were at least partly responsible for the growth depensation of the juvenile flounder. The dominants could not effectively defend the food in excess and disproportional food acquisition of the subordinates and dominants was not the primary mechanism responsible for the size hierarchy effect. In culture, size grading of the early juvenile flounder could markedly improve the growth and survival and thus possibly increase the overall biomass production of the flounder.

    Notes: Morphological changes are described in Japanese flounder Paralichthys olivaceus larvae and juveniles with emphasis on growth during the period of metamorphosis. Ontogenetic changes in condition factor and lipid, glycogen and protein levels were also analysed to determine the utilization of stored energy. Fish grew from 6·6 to 20·3 mm LT(1·15 to 84·4 mg in mass, M) during the period from 11 to 40 days after hatching (DAH) at 19·3° C. Per cent specific growth rate per day (%G day−1) for wet mass was lowest during the metamorphic phase (21–30 DAH) compared to pre-(11–20 DAH) and post-metamorphic (31–40 DAH) phases. When LT and M were expressed as 〈inlineGraphic alt="inline image" href="urn:x-wiley:00221112:JFB251:JFB_251_mu1" location="equation/JFB_251_mu1.gif"/〉, the b value was highest during the pre-metamorphic phase and lowest during the metamorphic phase. These findings indicate that the developmental changes that occur during metamorphosis of Japanese flounder are closely related to the growth pattern. Moisture, lipid and glycogen contents were also at the lowest level during metamorphosis compared to pre- and post-metamorphosis, which suggest that Japanese flounder use their energy reserves to accomplish metamorphosis due to an apparent decline in feeding during this period.
