Contrast enhanced ultrasound (CEUS) is useful to evaluate tissue perfusion in the kidney. In veterinary medicine, sedation or anesthesia may be required in uncooperative or panting patients. The aim of this study was to evaluate and compare the normal kidney perfusion patterns in conscious and anesthetized dogs using CEUS. Eight healthy beagles were used in this study. Scanning was performed in conscious dogs using manual restraint (conscious group), or under general anesthesia using tiletamine-zolazepam and medetomidine (TZM group) or medetomidine (M group). The contrast agent (Sonovue®) was administered as an IV bolus. The peak intensity (PI), time to peak enhancement from injection (TTP0) and the time to peak enhancement from the initial rise (TTPup), upslope, downslope and area under the curve (AUC) were analyzed. Compared to the cortical values in the conscious group, TTP0 was significantly delayed in the TZM group, and upslope, TTP0 and TTPup were significantly different in the M group. The AUCs in the TZM and M groups were not different from those in the conscious group. The upslope of renal medullary perfusion was significantly decreased in the TZM and M groups. TTP0 and TTPup were also significantly delayed in these groups. The AUC of the medulla was significantly decreased in the M group. Therefore, TZM is useful as an anesthetic protocol when performing CEUS, and the obtained data may serve as reference values in the evaluation of renal perfusion using CEUS in dogs under anesthesia.

A 3-year-old neutered female poodle with a long history of dermatophytic skin disease was presented with lethargy, anorexia and progressive weight loss. Abdominal ultrasonography revealed markedly enlarged mesenteric lymph nodes and multiple hypoechoic foci in the spleen. Cytology of the mesenteric lymph nodes and spleen showed granulomatous inflammation with fungal organisms and negatively stained intracytoplasmic bacterial rods consistent with Mycobacteria spp. Based on culture, multiplex polymerase chain reaction and sequence analysis, the bacterium was identified as Mycobacterium avium subspecies hominissuis. Despite treatment with antibiotics, the dog’s condition deteriorated, and it died approximately 3 weeks after first presentation.

This study examined the difference in dog owning between Japan and the United States, and the effect of these differences on dogs’ behavioral characteristics. Behavioral evaluations of privately-owned dogs were obtained by using online questionnaire. We compared background and demographic information from the two countries and analyzed the effects of these differences on behavioral characteristics in dogs. The results indicated that there was a bias in the dog breeds kept in Japan compared to the United States and that Japanese dogs’ body weight was lower than the US dogs. The main source of dog acquisition was pet stores in Japan and breeders and/or shelters in the United States. Multiple linear regression analysis found that Japanese dogs showed more aggression to household members and higher energy, restlessness and fear of non-social stimuli than US dogs, while US dogs showed more fear of unfamiliar persons, separation-related behavior and excitability. US dogs also showed higher levels of trainability and attachment to owners. The lower dog's body weight was, the higher the behavioral scores except for trainability were. When dogs that were obtained under 3 months of age were analyzed, the younger the dogs were when their owners obtained them, the higher the scores on some behavioral problem factors were. The higher rates of problem behaviors among Japanese dogs compared with US dogs suggest that the preference for small breed dogs and poor early development environment influenced the behavioral characteristics of dogs.

Two cats with abdominal effusion and anorexia were diagnosed as feline infectious peritonitis (FIP). We tried to evaluate the effect of thromboxane (Tx) synthetase inhibitor, ozagrel hydrochloride, on the progression of symptoms and clinicopathologic data characteristic to FIP. After administration of Tx synthetase inhibitor, improvement of appetite and activity, decreases of peritoneal effusion, reduction of leukocyte number to normal level, and improvement of hyper γ-globulinemia were found in 2 cats with FIP. These findings suggest that the vasculitis in FIP can be successfully treated with Tx synthetase inhibitor which inhibits platelet aggregation.

Three topics from electron microscopic studies of microorganisms carried out in my laboratory in recent ten years are described. 1) Influenza A virus was observed in water by an ice-embedding method using phase contrast electron microscopy developed in Japan. Virions appeared as spherical or elongated particles consisting of spikes, an envelope, and a core with high contrast. 2) A new term the “structome” was introduced and defined as “the quantitative and three-dimensional structural information of a whole cell at electron microscopic level.” We performed structome analyses of Saccharomyces cerevisiae by using freeze-substitution and serial ultrathin sectioning electron microscopy. We found that there were one to four mitochondria and about 195,000 ribosomes in a cell. 3) In the deep-sea off the coast of Japan, we discovered a unique microorganism appearing to have cellular features intermediate between prokaryotes and eukaryotes. The organism, named as the Myojin parakaryote, was two orders of magnitude larger than a typical bacterium and had a large “nucleoid”, surrounded by a single layered “nucleoid membrane”, and bacteria-like “endosymbionts”, but it lacked mitochondria. This organism exemplifies a potential evolutionary path between prokaryotes and eukaryotes, and the presence of the organism supports the endosymbiotic theory for the origin of mitochondria and the karyogenetic hypothesis for the origin of the nucleus. These studies show that the electron microscopy is a powerful tool for studying a wide range of problems of microorganisms.

Kombu, a palatable seaweed belonging to Laminariaceae, has often been used as a seasoning material for soups or vegetables in authentic Japanese cookery. The soup is especially rich in nutrients for bacterial growth. Therefore studies on the food hygiene of kombu extract were undertaken. The growth of bacteria adhering to the surface of kombu was observed in an extract of the plant. The following food poisoning bacteria, Salmonella enteritidis, Staphylococcus aureus, Vibrio parahaemolyticus, Clostridium perfringens and Cl. botulinum, were inoculated in kombu extract or artificial kombu medium. When the bacterial counts of cultures in natural kombu medium were compared with those in artificial medium, no remarkable differences in growth were observed in any of the bacterial species used. Judging from the experimental results, attention should be paid to contamination with S. enteritidis and St. aureus. With respect to the other three food poisoning bacterial species, the extract was considered to be relatively safe in food hygiene under the experimental conditions.

The performance of the ion thruster depends on the discharge performance and the beam extraction, the former of which is significantly effected by the electron property such as density and energy, since ions are produced by ionization collisions between neutral atoms and electrons. In the microwave ion thruster, the discharge owes to the electron cyclotron resonance (ECR). Thus, the electron phenomenon in the microwave discharge chamber was numerically investigated by the particle simulation method. In our model, the electromagnetic wave is polarized circularly and propagates in the axial direction and electrons are moved in the microwave and static magnetic fields, colliding with neutral particles. Collision processes are taken into account by the Monte Carlo method. This simulation results show that some electrons can be heated enough to cause ionization collisions and that the density and energy distributions are peculiar to the microwave ion thrusters.

和歌山県における面源汚染の実態を広域的に把握するため,土地利用と河川水質の関連性について,県内の18河川を対象に定量評価した.具体的には,河川水中の主要な溶存成分を測定し,GIS (Geographical information system)データを用いて算出した流域の土地利用面積割合との相関を調べた.その結果,北部・中央部(以降,北中部と記す)の河川で面源汚染が進んでいることが明らかとなった.これは,下水道普及率の低い和歌山県においては,住宅地が多い北中部で,面源負荷が多いためと考えられる.また,特に中部河川では,果樹園に由来する面源負荷も大きく,栽培する果樹の種類による施肥量の違いや,元々の土壌生産性,降水量などの自然条件の違いが影響しているとみられる.一方,南部の河川では,流域の大部分が樹林地に覆われ,人為的な環境負荷が少ないため,面源汚染の影響はほとんど見られなかった.

The linear Boussinesq equation should be used in numerical simulations for distant tsunamis in the Pacific Ocean, because the dispersion effect is not negligible. Its difference equation which can not be expressed by an explicit scheme requires a long CPU time. One of the present authors has introduced a new technique, in which the first term of discretization error in the difference equation of the linear long wave theory was used and controlled to replace the physical dispersion term. This method is applied in the present study. The effect of ocean current on the tsunami propagation is confirmed to be negligible in wave direction and wave height. The 1960 Chilean tsunami is simulated. The Coriolis force has not only the effect on the propagation direction but also the dispersion effect, which is examined by comparing with the computed result without the Coriolis force. Effect of the sea bottom topography is examined in detail in terms of wave energy. About 40% of initial wave energy remains on the continental shelf in the neighborhood of Chile, and the rest is radiated to the Ocean. After scattered and trapped by islands and sea mounts, about 25% of the total energy arrives at Japan. The computed results shows a fairly good agreement with tide records after making correction of the effect of the water depth. For further discussions of the tsunami in shallow seas, simulations should be performed using the shallow-water theory and detailed topography.

The purpose of this study was to clarify the characteristics and relationship between somatotype and standing posture in Judoists and Kendoists. In this study the 245 male athletes from 15 sports events at the University of Tsukuba were classified as to their body type by the Heath Carter somatotype method. And measurement was taken of the spine curvatures, the difference of bi-acromion height, the weight distribution between right and left foot and the location of center of gravity in anterior posterior axis of foot.The results were as follows:1. The characteristics in somatotype of Judoists showed large mesomorphic and endomorphic components. The somatotype of Kendoists showed resemblance to that of Soccer and Tennis player.2. The intensified dorsal curvature was one of the characteristics in Judoists' posture. Kendoists had a tendency to be inclined backward in head and neck position.3. Judoists who showed endomorphic mesomorph type had a tendency to be inclined backward in their upper bodies. And Kendoists who showed ectomorphic mesomorph type had a tendency to shift their weight forward.

Mitochondria play a central role in energy production but also are the main cellular source of reactive oxygen species (ROS). It is widely believed that aging is related to the accumulation of oxidative molecular damage due to ROS. Aging also induces a decrease in muscle function. Recent studies indicate that caloric restriction and physical exercise suppress the decrease in muscle function though the maintaining quality of mitochondria. This review provides the current understanding of the influence of caloric restriction and exercise on mitochondrial quality control in skeletal muscle.

乳癌集団検診の二次検診において,コンタクトサーモグラフィーを,マンモグラフィー,エコーグラフィーと共に補助診断法として用い,その有用性,限界について検討を行なった.使用したサーモブレートは,イタリアFinpat社製 “Breast Thermo Detector” であり今回は特に,腫瘤部の温度の高低に注目して診断した.その結果,乳癌症例の正診率は全体で68%, T>2cmでは86%, T〓2cmでは38%であった.病理組織学的には,線維腺腫,乳腺のう胞腫との鑑別は容易であったが,乳腺症との鑑別は難しかった.したがって,コンタクトサーモグラフィーは乳癌の精密検査法としての利用価値は低いとおもわれた.しかし,触診の補助診断法として用いることにより,手軽で安価な検査法としての利用価値があるのではないかと考えられた.

We investigated the seasonal correspondence between the fruiting phenology of fleshy-fruited plants and the abundance of frugivorous birds, in a temperate forest, in central Japan. The majority of fleshy fruits ripened in the fall when frugivorous birds were most abundant. This correspondence occurred earlier than in a warm temperate forest, located in southern Japan; these relationships in East Asia coincide with those of the temperate regions of North America and Europe. We also examined whether the abundance of frugivorous birds led to profitable effects for seed dispersal among fleshy-fruited plants. The Brown-eared Bulbul Hypsipetes amaurotis was considered to be an important seed disperser for many fleshy-fruited plants because of its high frequency of occurrence throughout the fruiting season, and its large gape size, which allowed it to swallow all sizes of fruits found at the study site. Although numerous Brown-eared Bulbuls and other frugivorous birds were present in the fall, fruit removal rates in fall-fruiting species were not always higher than in summer-fruiting species. The abundance of frugivorous birds alone could therefore not adequately explain the concentrated fruiting phenology among fleshy-fruited plants.
