Nagano Prefecural Nagano Senior High School

The purpose of this study was to examine the efficiency of the instruction focused on the rhythm of last three steps in the approach run in the long jump class and the high jump class of junior high school. The unit of 7 long jump classes and 8 high jump classes were focused on the rhythm up last three steps in the approach run, and the take-off movement in the first class and the last class were compared kinematically. Subjects in this study were 1st, 2nd and 3rd grade junior high school students, the number of students in the long jump class was 17 and that the high jump class was 22 .<br>

We developed a severe anaphylactic model in mice using buckwheat antigen and B-type CpG-oligodeoxynucleotides (CpG-ODNs) from Streptococcus thermophilus genome. In typical systemic anaphylaxis models, animals are challenged with large quantity of antigens via an intravenous (i.v.) route. Here, we showed a simple anaphylactic shock after challenge via intraperitoneal (i.p.) route. The i.p. method is simpler than i.v. administration and has a lower risk for failure. To generate this anaphylactic model, 5-week-old female BALB/c mice were first i.p. sensitized with buckwheat antigen mixed with B-type CpG-ODN. After 2 weeks, mice were challenged with antigen to induce anaphylactic shock, which was evaluated by scoring the severity symptoms and measuring serum levels of various proteins and splenic cell producing cytokines. Immunoglobulin (Ig)G2a production and interferon-γ positive cells were markedly increased in mice immunized with antigen mixed with B-type CpG-ODN, whereas serum IgE levels were decreased by B-type CpG-ODN. We also examined the effects of various ODNs (A, B and C-type CpG-ODNs) and antigens (buckwheat, α-casein, β-lactoglobulin and ovalbumin) on anaphylactic severity, and found that the combination of buckwheat and B-type CpG-ODN induced the most intense anaphylactic shock. This model is expected to contribute to the study of the prevention of anaphylactic shock.

Abstract In order to know the net deposition of major chemical components by precipitaion in the Honshu Island of Japan, each event rain was sampled for one year in 1983 at two sites; Komoro City, an inland city and Tsukuba Science City, which was located in the Pacific side. Both sampling sites were at the similar latitude and rural area of similar populations. The concentrations of hydrogen ion, chloride, nitrate, sulfate, sodium, potassium, calcium and magnesium ions were determined in each rain and summarized in the monthly basis. The concentrations of hydrogen, sulfate and nitrate ions were several times higher at Tsukuba than at Koraoro. The average pH at Tsukuba and Komoro were 4.54 and 5.34, respectively, the former apparently influenced by the polluted air from the industrial area including Tokyo and the latter comparatively free from it. Some discussions were done for the identification of sources for each chemical component.

1. Through the year 1968, size, structure and seasonal change of home range of Passer montanus were studied at Bundo village in Iiyama City, Nagano.2. Bundo is an isolated small village of only 12 houses situated 800m above the sea level, with maximum snowfall of over 2m.3. The annual life cycle could be divided into: 1) snow season 2) breeding season and 3) flocking season.4. The home range in snow season measured 11, 500m2, with activity concentration to resting and feeding places, which were in the center of village. The main food in early snow season was the seed of percimon.5. The home range in breeding season was the smallest measuring 9, 600m2, but gradually increased as the advance of breeding stage. The center of activity is directed to the nest and the vicinity.6. Entering the flocking season, the home range increased to 37, 200m2, expanding over rice fields The 96.6% of food consisted of the rice. The flock concentrates to a particular rice field.7. The lack of food during snow season urges them to spend 27.8% of the day in foraging and rest under the eaves and roofs.8. As the rice ripes, they get in the flocking season and spend only 11.9% of the day for eating, They rest 88.1% of the day gathering around Aralia cordata bush and reeds near the rice fields.9. The feeding places during snow and breeding seasons are almost all in the village (89.9% and 85.6% respectively), while in flocking season they feed 98.3% in the rice field.10. The home range consists of central and outer ranges. The central range is used through the year, with 3-8 times thicker concentration rate of activity loci than in the outer range. It is in the village and contains nest sites.11. In severe snow season, 65.8% of the home range is used, decreasing to 50.0% in breeding season. In flocking season, although the range increses, only 36.6% of the area is actually used, with 93.4% of the area left unused.12. Adult birds once settled lives within the selected home range throughout the year, strongly dependent on human houses.
