The forthcoming very elderly society threatens to render thehealth insurance system of Japan dysfunctional. To solve thisissue, a new screening and interventional program specificallytargeting metabolic syndrome commenced in April 2008. This program targeted individuals in the age group 40-74years. The program sought to prevent the risk of developmentof lifestyle-related diseases. In this review, we analyze 5-yearstatistical data, discuss the efficiency of the screeningprogram, and offer a brief explanation of the applicability ofinformation communication technology (ICT). Interventionwas effective to prevent metabolic syndrome based onphysiological parameters. Using ICT, a database has beencreated to collect both health checkup records and receipts. Computer- and Web-based health guidance has beenattempted but no reports thereon have yet been published. Further efforts should be made to improve the design, cost,and handling characteristics of both the software and hardware.

Placenta previa presents a highest risk to pregnancy, and placenta accreta is the most serious. Placenta accreta requires cesarean delivery and often results in massive obstetric hemorrhage and higher maternal morbidity. Challenges associated with cesarean delivery techniques may contribute to increased maternal blood loss and morbidity rates. Several recent obstetric studies reported the usefulness of transverse uterine fundal incision for managing placenta accreta. We present a case of placenta percreta that was treated by a transverse fundal incision. We successfully avoided cutting through the placenta and helped decrease maternal blood loss. After delivery, the patient underwent a cesarean hysterectomy. Postoperative day 48, she experienced watery discharge and was diagnosed with vaginal fistula. We present our case and review the literature.

Isotope ratio analysis of nuclear materials in individual particles is of great importance for nuclear safeguards. Although secondary ion mass spectrometry (SIMS) and thermal ionization mass spectrometry (TIMS) are utilized for the analysis of individual uranium particles, few studies were conducted for the analysis of individual uranium-plutonium mixed oxide particles. In this study, we applied SIMS and inductively coupled plasma mass spectrometry (ICP-MS) to the isotope ratio analysis of individual U-Pu mixed oxide particles. In the analysis of individual U-Pu particles prepared from mixed solution of uranium and plutonium standard reference materials, accurate 235U/238U, 240Pu/239Pu and 242Pu/239Pu isotope ratios were obtained with both methods. However, accurate analysis of 241Pu/239Pu isotope ratio was impossible, due to the interference of the 241Am peak to the 241Pu peak. In addition, it was indicated that the interference of the 238UH peak to the 239Pu peak has a possibility to prevent accurate analysis of plutonium isotope ratios. These problems would be avoided by a combination of ICP-MS and chemical separation of uranium, plutonium and americium in individual U-Pu particles.

In the analysis of individual U-Pu particles prepared from mixed solution of uranium and plutonium standard reference materials, accurate $^{235}U/^{238}U$, $^{240}Pu/^{239}Pu$ and $^{242}Pu/^{239}Pu$ isotope ratios were obtained with both methods. However, accurate analysis of $^{241}Pu/^{239}Pu$ isotope ratio was impossible, due to the interference of the $^{241}Am$ peak to the $^{241}Pu$ peak.

<P><B>ABSTRACT</B></P><P><I>Cryptosporidium andersoni</I> and <I>Cryptosporidium muris</I> infections have been found in the mice and/or cattle. The oocysts of <I>C. andersoni</I> and <I>C. muris</I> have been sporadically detected in human feces, but the infectious capacity and features have been unknown, because of the scarcity of reports involving human infections. To assess the infectivity and the clinical and pathological features of <I>C. andersoni</I> and <I>C. muris</I> in primates, an experimental infectious study was conducted using cynomolgus monkeys. The monkeys were orally inoculated with oocysts of two different <I>C. andersoni</I> Kawatabi types and <I>C. muris</I> RN-66 under normal and immunosuppressive conditions. The feces of the monkeys were monitored for about 40 days after the administration of oocysts using the flotation method, but no shedding oocysts were observed under either both normal or immunosuppressive conditions. Gross and histopathological examinations were performed on the immunosuppressive monkeys, but these revealed no evidence of <I>Cryptosporidium</I> infections, even though the monkeys were subjected to immunosuppressive conditions. It is hypothesized that <I>C. andersoni</I> and <I>C. muris</I> pose little danger of infection in primates even under immunosuppressive conditions.</P>
