    Notes: Xanthogranulomas develop in adults as well as in children; however, adult cases with multiple lesions are very rare. We report an adult who developed both multiple cutaneous lesions on the face and trunk and lesions on the conjunctiva, oral mucosa and genitalia. We believe that this is the first such case described.

    Notes: : Fermentation processes of bread doughs were traced by MRI (magnetic resonance imaging), which suggests that punching and rounding treatment after the first fermentation promotes the development of elasticity and extensibility of gluten fibrils that makes thin grain walls of the pores connecting between adjacent pores with small holes, and a thin smooth crust after baking. While pore generation was small, expansion of the dough was low, gluten networks formed were large and coarse, and gluten fibrils were undeveloped in the frozen dough. Prefermentation could not essentially alleviate the inferior properties of the frozen dough. The grain structures of the bread using frozen dough were characterized by thick network walls without the connection between pores and a thick crust with rough surface.

    Notes: The fermentation process for frozen doughs using freeze-sensitive (Saccharomyces cerevisiae, Kyowa for sweet bread; S. cerevisiae, FC for white bread) and freeze-tolerant (S. cerevisiae, YF for sweet bread) yeasts was traced by magnetic resonance imaging (MRI). Grain network structures of baked breads were also visualized by MRI. Prefermentation before freezing, punching and remolding, or resheeting and molding treatments increased loaf volume by 10 to 110% for the baked breads using freeze-tolerant yeast, while these treatments decreased loaf volume by 70% using freeze-sensitive yeast. The first fermentation before freezing and the second fermentation with punching or resheeting after thawing are useful for obtaining good quality breads from frozen dough using freeze-tolerant yeast.

    Notes: The distribution and fluctuation of sugars in germinating barley seeds were examined by 13C nuclear magnetic resonance (NMR) spectroscopy, 1H-NMR imaging and 1H-NMR localized spectroscopy in relation to morphology. Maltose, sucrose, fructose and oils were detected in intact imbibed seeds by 13C-NMR spectra. During the first 6 d of germination, the maltose content increased and the oil content gradually decreased, whilst the levels of sucrose and fructose remained constant. Sugars were located by 1H-NMR images and 1H-NMR localized spectra in the vascular bundle of the seeds as well as in the solubilized endosperm. They were also detected in the shoots. The sugars detected in an 80% ethanol shoot extract were sucrose and glucose, which were located in the vascular bundles but not in the mesophyll cells of the coleoptile. They were also located in the basal part of the shoot, but not above 7 mm from the scutellum. The data suggest that the sugars are primarily transported through the vascular bundles and, at the same time, rapidly incorporated into mesophyll cells in the leaves.

    Notes: In order to examine the transverse distribution of scattered light and chlorophyll fluorescence in intact rice leaves, a micro-fluorescence imaging system was devised using a microscope, a CCD camera with an image intensifier, an Ar and a He-Ne laser light source, an image processor, and a microcomputer. A laser light was projected vertically on to the surface of a rice leaf segment at a cut-edge, and scattered light and induced fluorescence were observed at the cut-section from a 90° angle to the axis of the laser beam. The intensity of scattered light showed a maximum at several micrometres depth from the leaf surface and a steep gradient afterwards. Fluorescence reached a maximum crossing with the decline curve of the scattered light. The maximum of fluorescence measured at 741 nm was observed at a greater depth from the leaf surface than that at 687 nm, suggesting that part of the fluorescence of the longer wavelength was emitted due to absorption of fluorescence of the shorter wavelength. Profiles of the scattered light and the chlorophyll fluorescence depended on leaf anatomy.

    Notes: Abstract. Activation spectra of photochemical reactions were measured by a flash spectrophotometer in leaves having varying chlorophyll contents at different stages of greening. The increase of chlorophyll concentration up to 30 nmol cm-2 elevated the rates of photochemical reactions at all wavelengths of light used, and was found to be produced by an increase in the amounts of reaction centres. Further accumulation of chlorophyll up to 40 nmol cm-2 was associated with an increase in light-harvesting chlorophyll, an improved rate of photochemical reactions around 600 nm and at 700 nm, and self-absorption and screening effects where chlorophyll absorbed maximally (400–450 nm and around 680 nm).
