Tertiary Formations in the Yuya-wan (bay) District, Southwest Japan, with References to the Tertiary Geologic History of West Chugoku

This paper treats of the problems concerned with the geology of the Cenozoic strata developed in the Yuya-wan (bay) district of West Chugoku, the Inner side of Southwest Japan. On the basis of the data obtained through his study the writer summarizes the stratigraphy and structure of this district, and gives the correlation among the Tertiary formations of the Saikai, in which the Yuya-wan district is included, Setouchi and San-in sedimentary provinces. As a result of the study, the writer remarks the Mid-Tertiary geologic history and paleogeography of West Chugoku

Regulation of bone by the adaptive immune system in arthritis

Studies on the immune regulation of osteoclasts in rheumatoid arthritis have promoted the new research field of 'osteoimmunology', which investigates the interplay between the skeletal and immune systems at the molecular level. Accumulating evidence lends support to the theory that bone destruction associated with rheumatoid arthritis is caused by the enhanced activity of osteoclasts, resulting from the activation of a unique helper T cell subset, 'Th17 cells'. Understanding the interaction between osteoclasts and the adaptive immune system in rheumatoid arthritis and the molecular mechanisms of Th17 development will lead to the development of potentially effective therapeutic strategies

ブドウ”巨峰”に対する摘葉と施肥時期が夏季せん定後の新梢の生長と果実生産に及ぼす影響

In tropical countries, grapevines grow as evergreen and they are pruned in the time of active growing. In such summer pruning, defoliation of mature leaves and application of fertilizers are recommended for promoting bud bursting. Using the cultivar Kyoho, we conducted summer pruning and tested the effect of defoliation and fertilizing time on the growth of new shoots and flowering. On the basis of the results, we discussed the nutritional condition of the vine. 1. When all leaves were defoliated from the primary shoot at summer pruning, bud bursting was delayed and the growth of new shoots was much reduced. The development of flower clusters was restricted severely, and the berries set were only few. 2. Chemical analysis of the leaves developed on new shoots showed that defoliated vines contained less starch than un-defoliated vines. Nitrogen content was also lower in defoliated vines at the early stage of shoot growth. The nitrogen content decreased rapidly as the shoot grew in un-defoliated vines, while it increased until blooming in defoliated vines. Sugar content was also higher in defoliated vines than in those of un-defoliated. These results may be an indication that the nutrient movement to growing shoot tip or flower cluster was inactive in defoliated vines. 3. Application of fertilizers in two weeks before pruning to the un-defoliated vines resulted the longest shoot growth, though the flower development was best in the vines applicated on the same day with pruning. The highest berry setting percentage was obtained by application in two weeks after pruning

Hemosuccus Pancreaticus following a Puestow Procedure in a Patient with Chronic Pancreatitis

Hemosuccus pancreaticus is an unusual cause of gastrointestinal bleeding that occurs as a complication of chronic or acute pancreatitis. We report a case of extremely acute-onset hemosuccus pancreaticus occurring in a patient with chronic pancreatitis over a long-term follow-up after a Puestow procedure (side-to-side pancreaticojejunostomy). The patient was admitted to our hospital due to severe anemia and tarry stools indicative of gastrointestinal bleeding. Emergent endoscopy, including gastrointestinal fiberscopy and colon fiberscopy, showed no abnormal findings. Abdominal contrast-enhanced computed tomography and hemorrhagic scintigraphy did not detect a hemorrhagic lesion. Although interventional radiology was considered for diagnosis and treatment, conservative therapy seemed sufficient to affect hemostasis. Two weeks later, however, acute intestinal bleeding with hemodynamic shock occurred, and exploration was performed without delay. Intraoperative endoscopy through an incision of the reconstructed jejunal loop in the close proximal end revealed a site of active bleeding from the side-to-side anastomotic pancreatic duct. Following a longitudinal incision of the jejunal loop, a bleeding point was sutured and ligated on direct inspection. The patient showed a good postoperative course

ブドウ’巨峰’に対する施肥時期に関する研究

The experiment was carried out with three years old 'Kyoho' grapevines planted on gravelled beds. Applications of aqueous fertilizer were started at different times from autumn to spring. Effectiveness of each application was determined by measuring vine growth and fruit productivity and also by analysing the nutrient contents in root, cane and leaf at several times. Applying fertilizer in autumn increased the N content of root and cane even during winter and resulted in earlier and more dud bursting and better development of flower cluster. Application from March or April caused a rapid increase in N content of root and cane at bud bursting. The greatest shoot length and the largest ovary size were measured at blooming, and a better crop with larger sized berries and good qualities was yielded on the vines fertilized in spring
