    Notes: Summary Enamel proteins were extracted from the newly formed layer of immature porcine enamel, and the 25 kDa amelogenin, 89 kDa enamelin and 13–17 kDa nonamelogenins were purified. Specific antisera were raised against these proteins. Antibodies specific to the C-terminal region (residues 149–173) of the 25 kDa amelogenin were generated by absorption of the anti-25 kDa amelogenin serum with 20 kDa amelogenin, which contains residues 1–148 of the antigen. Immunoelectrotransfer blotting of the extracted porcine enamel proteins showed that the anti-25 kDa amelogenin serum recognized the 25 kDa and other low and high molecular weight amelogenins. The C-terminal specific anti-25 kDa amelogenin serum reacted only with amelogenins having molecular weights over 23 kDa. The anti-89 kDa enamelin serum recognized the 89 kDa enamelin and lower molecular weight proteins, but neither the amelogenins nor the 13–17 kDa nonamelogenins. The antiserum against the 13–17 kDa nonamelogenins showed no cross reactivity to the 89 kDa enamelin, but recognized higher molecular weight nonamelogenins. In immunohistochemical preparations of the porcine tooth germs, the 25 kDa amelogenin-like immunoreactivity over immature enamel decreased in a gradient from the enamel surface to the middle layer. In the inner layer immunoreactivity was concentrated over the prism sheaths. The C-terminal specific 25 kDa amelogenin-like immunoreactivity was intense at the outer layer of immature enamel and decreased sharply toward the middle layer. Prism sheaths were intensely stained by the antiserum to the 13–17 kDa nonamelogenins. The 89 kDa enamelin-like immunoreactivity over enamel prisms was intense at the outer layer and decreased toward the middle layer. Staining by the anti-89 kDa enamelin serum of prism sheaths was faint. In immature rat incisor enamel, the C-terminal specific 25 kDa amelogenin antiserum demonstrated a staining pattern similar to that in the immature enamel of the pig. Distinct 13–17 kDa nonamelogenin-like and 89 kDa enamelin-like immunoreactivities were found especially in the layer adjacent to the Tomes' process. We conclude that some enamel proteins are degraded soon after their secretion from the secretory ameloblast in the rat and the pig. The specific enamel proteins which reacted with the antiserum to the 13–17 kDa nonamelogenins seem to be involved with the formation of prism sheaths in immature porcine enamel, but not in rat incisor enamel.

    Notes: Summary Antigenic variation of pseudorabies virus glycoprotein g II was demonstrated in field isolates by neutralizing monoclonal antibodies. Mutants capable of avoiding neutralization by the monoclonal antibodies specific for glycoproteins g II and g III could be obtained from the parent virus by mutagenesis.

    Notes: Abstract Distributions of238U and226Ra in agricultural samples and cultivated soils have been studied over ten years. The crops are rice, spinach and Chinese cabbage. Two investigated areas have been selected (35° 18′ N, 113° 35′ E). The agricultural samples and soils were collected annually from May 1982 through October 1991. The activity concentrations of226Ra in agricultural samples are greater than those of238U. The transfer factors of238U,226Ra are from 0.06·10−3 to 1.2·10−3. The226Ra/238U ratios for three agricultural samples have their characteristic values.

    Activity concentration of226Ra and238U in various soils (1992)

    Notes: Abstract The distribution of226Ra and238U in various soils has been studied. Supposing that radioactive equilibrium were in existence, the average activities of226Ra and238U would show a nearly 1∶1 correlation. As weathering affects radioactive equilibrium in surface soil, radioactive equilibrium was not in existence. Therefore, four kinds of soil were selected from different weathering conditions, viz. river bed soil, paddy field soil, field soil and uncropped soil. The226Ra/238U ratio of various soils lies in the range of 1.63 to 2.41. The activity concentrations of226Ra were greater than238U in various soils. The ratio226Ra/238U can be shown to be a quantitative index of weathering. Phosphatic manure contains238U and its daughter isotopes in concentrations far exceeding the average abundance in the earth's crust. But the cultivated soils (paddy field soil, field soil) are not affected by fertilizers in Kamisaibara.

    Tidal pump at the shelf edge (1992)

    Notes: Abstract Material transport through the shelf edge to the deep ocean determines the fate of particulate matter generated in productive coastal seas. In stratified estuaries, onshore flow in the bottom layer generally keeps particulate matter generated in the upper layer and settled down to the bottom layer within the estuaries. AT the shelf edge of Tokyo Bay under the condition of average onshore flow in the bottom layer, we observed higher vertical sediment flux during ebb than flood tidal currents. The on-shelf and off-shelf differences in turbulent mixing and water depth mainly cause such difference in sediment flux. We propose to call this export process of particulate matter “the tidal pump” at the shelf edge.
