Giardia intestinalis is a protozoan parasite found in the intestinal tract of humans and animals. Recent molecular studies show considerable genetic diversity among isolates from humans and animals, suggesting that this species is not a single species but is composed of multiple genotypes that have zoonotic potential or are host-adapted. Cross-infection studies using the isolates from different hosts and molecular epidemiological studies in endemic areas strongly support the zoonotic transmission of G. intestinalis. Molecular analysis of the isolates is therefore essential in order to reveal the sources of Giardia infection and thus develop appropriate countermeasures. In Japan, the molecular epidemiology of Giardia infection is as yet unclear as only a few isolates from humans and animals have been genotyped. This report finds that further studies are required for an understanding of the zoonotic significance and molecular epidemiology of Giardia infection in Japan.

In recent years, computer hardware has become more powerful and more popularized. Software for specialized data processing, such as statistical analysis, is also becoming common as a result of the open-source movement. These changes have made some novel statistical techniques more accessible. Typical examples are the randomized test and the Monte Carlo method, which are now used frequently by some skilled researchers. Among average users, however, the use of such techniques is not common. In the present paper, I present these techniques and the R codes necessary to estimate parameter distribution with the Monte Carlo method.

As food apparatus, containers and packages are necessary in daily life, they must not contain harmful chemicals that could migrate to food. Investigations are necessary in this respect to confirm their safety. This review introduces recent problems and topics relating to the hygiene of food apparatus, containers and packages. The topics are as follows: di-2-ethylhexyl phthalate from polyvinyl chloride products, bisphenol A from polycarbonate and epoxy resin products, epoxidized soybean oil and semicarbazide from bottle cap sealing agents for infants, PFOA from fluoroplastics and the fluorine coatings, lactic acid from polylactide, and abietic acids from paper products.

To test the idea that concentration of air pollutants such as NOx, CO and SPM is significantly increased in enclosed spaces frequented by automobiles, an investigation of air pollution at a 52-space underground parking lot was carried out. Average concentrations of NO2, NO, CO, SPM and HCHO were 103ppb, 221ppb, 8.7ppm, 20.7μg/m3 and 18.0ppb respectively. Concentrations of NOx and CO were significantly higher than outdoors. Correlation between NOx and CO concentrations and the number of parking cars was not high, because the automobile sources of the pollutants were immediately present.

Textbooks and papers from both the social and the natural sciences were reviewed in the context of the concept of the environment and the subject matter of environmental biology. Basing on the results, the author concluded that the environment is a subject-dependent entity that is realized only when we take into consideration a living organism as subject, including humans. The human environment consists of many environmental factors, each of which is distributed, at a distance from a human or human group as subject, in an epistemological, non-physical space. A human subject can shorten the epistemological distance from its environmental factors by intensifying recognition of the environment. We can thus recognize the global environment in spite of its physical distance from our bodies. Environmental biology is an environmental science which deals with complex interactions in humans as subject, other living organisms as “second subject” and their environments. The major issues of environmental biology are the human impact on living organisms and vice versa, the impact of living organisms on environments and vice versa, the conservation or reconstruction of biological diversity, and, as a final goal, the establishment of sustainable coexistence between humans and other living organisms.

Physical properties and chemical reactivities of an unknown chemical compound can be predicted by the thermodynamic quantities of that compound. There are so many isomers and congeners among dioxin analogues that it is impossible to measure the thermodynamic properties of all such compounds. In this case, we can compute these quantities based on quantum chemistry. This report summarizes the thermodynamic properties of dioxins based on computational chemistry and toxicity based on the QSAR method. Equations predicting PXDD and PXDF free energy were also derived using a quantum and deductive chemical approach.

Pathogenic analysis of clinical samples to detect the causative agent is the most reliable method of confirming infection. Morphological examination using light microscopy is a convenient tool, but the information thus obtained is limited. In Japan, while morphological examination is still the gold standard in many parasitic infections, recent molecular studies have produced a wealth of new findings helpful in the diagnosis, treatment and prophylaxis of parasitic infections. Currently, genetic examination is applied in the diagnosis of various infectious diseases to obtain rapid and accurate results and also to understand their molecular epidemiology. It is expected that molecular methodologies will be necessary for the diagnosis of various parasitic infections. In the present paper, the author summarizes the significance and prospects of genetic examination in parasitic infections.

Anisakids are parasitic nematodes infecting fish and mammals. It is well recognized that human infection with this parasite, called anisakiasis, occurs by ingestion of raw or undercooked fish. In Japan, there are estimated to be over 1,000 cases of this infection annually. In 1999, “The Food Sanitation Law Enforcement Regulation” was partly amended, and anisakiasis was newly added to the causative agents of food poisoning. Identification of anisakid larvae has been performed by light microscopy, but it is impossible to accurately identify the worms morphologically when only small portions of the worm are available. In the present study, we showed the usefulness of PCR-based methods for identification of anisakid species using several species of anisakid larvae from Pacific cod. The larvae identified morphologically as Anisakis simplex or Contracaecum osculatum were found also to be positive for PCR amplification with only species-specific primers. In addition, the larvae of Pseudoterranova decipiens, frequently found in anisakiasis in Japan, were positive for amplification with only the P. decipiens-specific primers designed for the study. PCR using species-specific primers is thus concluded to be a useful tool for identification of anisakid larvae when morphological identification is impossible.

新品種のメロンの成分について分析して次の結果を得た。水分, たん白質は成分表値に比較してやや高く, 逆に炭水化物は低かった。脂質, 灰分は成分表値とほぼ同じ値であった。無機質ではカルシウムとリンが成分表値より低く, ナトリウムと鉄が逆に高かった。カリウムはナトリウムの10倍近い値を示した。ビタミンCは成分表値より低かったが, 果実類の中では柑橘類に次ぐ高い値であった。メロンの保存状態と品質保持との関係を調べたところ, 無包装で室温に置くと10%もの減少を示し旗が, ラップで包み, 冷蔵庫に置くと変化は1%以下であった。すなわち保存する際にはそれらの条件を守る必要がある。

The anti-fatigue properties of odorless garlic extract (OGE) were investigated by monitoring the recovery rate from muscular fatigue in anesthetized rats. In the experiment, muscular fatigue was induced by applying rapid electric stimulations to the skeletal muscle. Fatigue recovery rates were measured after a 60- and a 90-minute interval in the treated group and the control group, respectively.The results indicated that OGE had a certain degree of anti-fatigue effect (p<0.1) in the treated group (1g/kg/day oral administration of OGE for 14days). No significant body weight change in either group was observed during the experiment period, suggesting that OGE is safe at the dosage given (1g/kg/day).
