    Notes: . Cysts of an oligotrich ciliate were collected from natural sediment samples in Onagawa Bay, northeastern coast of Japan, and examined for their excystment capability. A high excystment ratio was obtained at lower temperatures of 10 or 15°C; no excystment occurred at 20°C. Excysted vegetative cells were observed after protargol staining and were identified as a new species, Cyrtostrombidium boreale n. sp. The seasonal changes in the vegetative population and sedimentation of newly formed cysts were also investigated in situ. Planktonic vegetative cells were abundant during the cold season from February to May, when the water temperature was lower than 10°C. Mass encystment occurred abruptly just after the seasonal peak of the vegetative population in April. These results indicate that C. boreale is a cold-water species and aestivates during the longer, warm period from late spring to fall.

    Notes: Abstract Levels of antithrombin III (AT-III) activity and antigen in plasma and urine in children with renal diseases, and their correlation with the light microscopic findings of kidney tissue and the fluorescence of glomeruli, were investigated. AT-III activity in plasma was reduced slightly during the acute stage of acute glomerulonephritis and moderately in the relapse stage of nephrotic syndrome, whereas a small increase of AT-III antigen level in urine was noted in the acute stage of glomerulonephritis and considerably more was observed during the relapse stage of nephrotic syndrome. During the acute stage of glomerulonephritis or in some primary persistent glomerulonephritis (IgA nephritis, non-IgA nephritis), Henoch-Schönlein purpura nephritis and nephrotic syndrome, localization of small amounts of AT-III was noted on the capillary walls of glomeruli. These findings were in parallel with the proliferative changes of glomeruli. However, the AT-III localization did not change in parallel with the light microscopic findings or degree of the fluorescence of the fibrinogen/fibrin-related antigen. It was thought that the existence of AT-III antigen on the capillary walls of the glomeruli might be associated with the inhibition of excessive fibrin formation by AT-III.

    Notes: Abstract Measurements of serum cortisol and gastrin along with gastric acid-pepsin secretion in the resting state were carried out in gastric and duodenal ulcer patients. Increased basal corticosteroid concentrations were observed in patients with duodenal ulcer and gastric ulcer. Higher concentrations of the hormone were observed in the former group (P〈0.05 for the latter). Fasting gastrin levels were significantly higher in gastric ulcer patients where gastric secretion is low than those in duodenal ulcer patients (P〈0.001). These results suggest that the effect of adrenal cortical hormone on lowering the threshold of oxyntic gland cell reactivity against gastrin is an important factor in duodenal ulcer etiology. Extra-antral control mechanism(s) of gastric acid-pepsin secretion should not be overlooked.

    Notes: Abstract Regional and vertical distribution of the microzooplankton in the Philippine and the Celebes Seas is reported in relation to the phytoplankton distribution. The maximum concentration of chlorophylla occurred at the surface in the Celebes Sea and in subsurface layer (50–150 m depth) in the Philippine Sea. On the other hand, the maximum occurrence of the microzooplankton was observed in the subsurface layer (50–150 m) throughout these sea areas; discrepancy in the vertical positions of the chlorophylla and microzooplankton maxima was observed in the former sea area. The higher dominancy of large-sized phytoplankton such as diatoms andTrichodesmium at the surface maximum, probably because most large-sized phytoplankton were uningestible for the microzooplankton, was the main reason why the discrepancy existed in the Celebes Sea. In the Philippine Sea, where the subsurface chlorophylla maximum layer was formed mainly by small-sized phytoplankton such as coccolithophorids and small dinoflagellates, such a discrepancy was not observed. These may indicate the establishment of a close food relationship between the microzooplankton and the small-sized phytoplankton rather than to the large-sized phytoplankton.

    Notes: Abstract Vertical distribution of phytoplankton in early warming season in the eastern Bering Sea and adjacent sea areas was investigated. In the surface layer which was under the influence of newly melted sea ice in the shelf water region of the Bering Sea in May, remarkably dense populations ofThalassiosira hyalina andT. nordenskiöldii and relatively large populations ofFragilaria andNavicula occupied large part of phytoplankton community. In June, although theThalassiosira populations sunk into the bottom layer and withered, a certain part of theFragilaria-Navicula populations was still suspended in subsurface layer. Thus,Fragilaria-Navicula were the leading components of the June community in the shelf region. In the Bering Basin region, no dense phytoplankton populations were developed until a shallow thermocline was established. In June when the shallow thermocline developed near shelf edge,Thalassiosira decipiens burst out. As the shallow thermocline extended from near shelf to central part of the Basin region with surface warming, the areas of blooming also shifted from near shelf to the central part.

    Notes: Abstract Quantitative data on the vertical distribution and biomass of microzooplankton are presented for the western subtropical Pacific west of the Bonin Islands in winter. Microzooplankton other than foraminifera and radiolarians showed similar vertical distribution to chlorophylla. Among microzooplankters, naked ciliates, tintinnids and copepod nauplii were dominant components both in number and volume. Naked ciliates were the most dominant, comprising 82.2 % and 47.7 % of the total microzooplankton by number and volume, respectively. Copepod nauplii, occupying less than 10 % by number, accounted for 35.7 % of the volume of all microzooplankton. Tintinnids contributed less to the microzooplankton standing crop, 12.6 % of the total by number and 17.3 % by volume. Calculated microzooplankton wet weight varied from 0.84 to 1.80 g m−2 and corresponded to 9.9–18.1 % of net zooplankton weight. The relative abundance of microzooplankton to net zooplankton in this study is comparable to that previously reported in the tropical and subtropical Pacific Ocean, but a little higher than in oceanic subarctic areas.

    Notes: Abstract A study of planktonic foraminiferal shells collected in the northern Pacific and the Bering and Chukchi Seas revealed that the number of chambers was large in layers above and in the thermocline but small in the underlying layer. The mean number in both strata was 6.2±0.65 and 4.1±0.36, respectively. This observation indicates that the recruitment of foraminifera occurs at depth and juveniles grow in the productive surface layers.
