Statistical Analysis of Hiroshima Bunrika University Students in the Prewar Showa Era

In this thesis, I analyzed student information of Hiroshima Bunrika University during the prewar Showa era. The results of this analysis showed that 60% of the students were incumbent teachers. Until now, Hiroshima Bunrika University had been considered a “teacher training university”. However, if a majority of the students were incumbent teachers, it could be said that Hiroshima Bunrika University was a re-educational institution. In addition, I found that Hiroshima Bunrika University students were enthusiastic about studying, had good job hunting experiences, and that there were few retirees and dropouts. These points should be understood as characteristics of a re-educational institution for incumbent teachers

Relationships between Students' Self-Educational Ability in Their College Age and Personal Teaching Theory (PTT) in their High School Age

This study investigated the relationships of students' self-educational ability in their college age with their personal teaching theory (PTT) in their high school age. A total of 789 students completed two kinds of questionaires, one of which was to measure their selfeducational ability (interest in learning subjects, self-directed thinking, skillfulness of learning method, self-monitoring, planning, independence, and self-actualization) in their college age and the other was to measure their personal teaching theory in their high school age. The major findings were as follows: (1) The students who wished to go on to higher level of education in their high school age showed more self-educational ability than those who did not wish to go on to higher level of education, and (2) the personal teaching theory of the students who wished to go on to higher level of education was more acive and self-regulational in their high school age. These results were discussed in relation to how to foster the self-educational ability of students

Jungle Honey Enhances Immune Function and Antitumor Activity

Jungle honey (JH) is collected from timber and blossom by wild honey bees that live in the tropical forest of Nigeria. JH is used as a traditional medicine for colds, skin inflammation and burn wounds as well as general health care. However, the effects of JH on immune functions are not clearly known. Therefore, we investigated the effects of JH on immune functions and antitumor activity in mice. Female C57BL/6 mice were injected with JH (1 mg/mouse/day, seven times intra-peritoneal). After seven injections, peritoneal cells (PC) were obtained. Antitumor activity was assessed by growth of Lewis Lung Carcinoma/2 (LL/2) cells. PC numbers were increased in JH-injected mice compared to control mice. In Dot Plot analysis by FACS, a new cell population appeared in JH-injected mice. The percent of Gr-1 surface antigen and the intensity of Gr-1 antigen expression of PC were increased in JH-injected mice. The new cell population was neutrophils. JH possessed chemotactic activity for neutrophils. Tumor incidence and weight were decreased in JH-injected mice. The ratio of reactive oxygen species (ROS) producing cells was increased in JH-injected mice. The effective component in JH was fractionized by gel filtration using HPLC and had an approximate molecular weight (MW) of 261. These results suggest that neutrophils induced by JH possess potent antitumor activity mediated by ROS and the effective immune component of JH is substrate of MW 261

Clinical benefit of readministration of gefitinib for initial gefitinib-responders with non-small cell lung cancer

BACKGROUND: Gefitinib, an oral agent of epidermal growth factor receptor tyrosine kinase inhibitor, has a certain efficacy against non-small cell lung cancer (NSCLC). Several predictive factors of gefitinib sensitivity have been well described. However, few studies have investigated the clinical features of gefitinib-responders. In the present study, we analyzed the response and disease progression of primary and metastatic lesions to gefitinib in responders and the results of gefitinib readministration following temporary cessation of gefitinib upon progression of initial gefitinib treatment and other treatments. METHOD: We retrospectively evaluated the clinical courses of 27 NSCLC patients who received gefitinib and achieved either a complete or partial response. RESULTS: The best-response rate and disease-control rate against the initial chemotherapy for the gefitinib-responders were 27.3% and 77.3%, respectively. Favorable efficacy was observed in the primary lesion and metastases to the lung, liver and brain, while there was no obvious effect on bone metastasis. The primary lesion and intrapulmonary metastasis were the sites of major recurrence. Median progression-free survival was 13.8 months, median duration of gefitinib treatment was 17.0 months and median overall survival was 29.2 months. Some of the patients who experienced disease progression after responding to gefitinib were again sensitive to readministration of gefitinib following temporary cessation of gefitinib and other treatments. CONCLUSION: Patients may still be expected to have prolonged survival if they once responded to gefitinib and then underwent various subsequent treatments followed by readministration of gefitinib. These findings might provide valuable information for the management of gefitinib-responders
