Do Education Vouchers Prevent Dropouts at Private High Schools? Evidence from Japanese Policy Changes (Japanese)

Although education voucher programs for students attending private high schools have existed in Japan for decades, as yet there have been no studies that examine their effectiveness. In this paper, we estimate the programs' preventative effect on dropouts using school-track level (academic or vocational) panel data covering all high schools in northern Japan. Facing increasing dropouts due to financial difficulties, prefectural governments have expanded the scope and amount of their private high school tuition support programs since the late 1990s. We use this variation to identify the effect of tuition support on students' decision to dropout, controlling for initial ability of entering students as well as unobservable school-track effects. We also apply the instrumental variable method to account for the possible endogeneity of policy changes. Our results suggest that increasing tuition support is particularly effective in preventing dropouts of private high school students in nonacademic tracks.

Candida albicans keratitis modified by steroid application

The paper reports on Candida albicans ocular infection modified by steroid eye drops. A 74-year-old male complained of conjunctival injection and pain in his right eye three months after pterygium and cataract surgery. After treatment with antibiotics and steroid eye drops for three days, he was referred to our hospital. Clear localized corneal endothelial plaque with injection of ciliary body was observed. No erosion of the corneal epithelium, or infiltration of stromal edema was observed, suggesting that the pathological organism derived from the intracameral region. Because ocular infection was suspected, steroid eye drops were stopped, which led immediately to typical infectious keratitis in the pathological region, with epithelial erosion, fluffy abscess, stromal infiltration, and edema. For diagnostic purposes, the plaque was surgically removed with forceps and the anterior chamber was irrigated with antibiotics. The smear and culture examination from the plaque revealed C. albicans surrounded by neutrophils. However, aqueous fluid and fibrous tissue after gonio procedure contained no mycotic organisms. Topical fluconazole, micafungin, and pimaricin with oral itraconazole (150 mg/day) were effective. Special attention is needed when prescribing steroid eye drops to treat corneal disease especially postoperatively. Diagnosing infectious keratitis is sometimes difficult because of modification by some factors, such as postoperative conditions, scarring, and drug-induced masking. Here, we report on mycotic keratitis modified by postoperative steroid administration

ペプシンとパンクレアチンを用いた酵素分析法のキノコ食物繊維定量への応用

A modified pepsin/pancreatin method was applied for the determination of dietary fibers in cultivated type mushroom. The results of histochemical examinations indicate that the hypha, basidium and basidiospore cell walls of the sample mushroom contained chitin but no cellulose, lignin nor starch. A small amount of insoluble pectin was observed in the hymeiuym. These cell wall components showed no change after the pepsin/ pancreatin treatment. On the other hand, protein reactions of protoplasm of various cells completely disappeared after the pepsin/ pancreatin digestion, except a few sclerenchyma and basophilic hyphae. The obtained data by this pepsin/ pancreatin method were compared with those by AOAC method in an analytical test. The total dietary fiber (TDF) values obtained by the pepsin/ pancreatin method were constantly higher than those by AOAC method

Interrelationships Between Serum Levels of Procalcitonin and Inflammatory Markers in Patients Who Visited a General Medicine Department

Various laboratory markers of inflammation are utilized in general practice, but their clinical diagnostic significance is often ambiguous. In the present study, we determined the clinical significance of the examination of serum levels of procalcitonin (PCT) by comparing the PCT levels with the levels of other inflammatory markers, based on a retrospective review of 332 PCT-positive patients, including cases of bacterial infection (20.5%), non-specific inflammation (20.8%), neoplasm (9.9%), connective tissue diseases (8.4%), and non-bacterial infection (7.2%), were analyzed. The serum PCT level was highest in the bacterial infection group (1.94 ng/ml) followed by the non-specific inflammatory group (0.58 ng/ml) and neoplastic diseases group (0.34 ng/ml). The serum PCT level was positively correlated with serum levels of C-reactive protein (rho=0.62), soluble interleukin-2 receptor (sIL-2R; rho=0.69), and ferritin, the plasma level of D-dimer, and white blood cell count, and negatively correlated with the serum albumin level (rho=−0.52), hemoglobin concentration, and platelet count. The serum PCT level showed a stronger positive correlation with the serum sIL-2R level than the other biomarkers. The results suggest that an increased PCT level may indicate not only an infectious state but also a non-bacterial inflammatory condition in the diagnostic process in general practice
