    Many athletes wear a collar containing aquatitan when playing a game, and this type of collar is said to have various good effects. Recent experiments showed the effects of aquatitan on animals. However, there are no reports of the effects on dogs wearing an aquatitan-containing collar. In the present study, the changes in behavior of two dogs with an aquatitan-containing collar were examined before and after the attachment. The dogs became more active when wearing the collar. Moreover, five beagles with a collar containing aquatitan and five control beagles were given a three-hour stress test of transportation by car. As stress markers, the number of white blood cells, number of lymphocytes, serum cortisol levels, and saliva chromogranin A levels were examined. All items showed stress patterns, and there was no difference between the two groups of dogs. However, while all the dogs suffered stress, the relative value of serum cortisol was significantly lower in the collar-wearing dog than in the control group. These results suggest the possibility of a cortisol suppressant effect of an aquatitan-containing collar on dogs.

    The findings of radial endoscopic ultrasound (EUS) and abdominal ultrasound (AUS) in the descending part of the duodenum in healthy dogs were compared, and the usefulness of radial EUS was assessed. Like AUS, radial EUS could distinguish the layered structure of the duodenum, i.e., the mucosal layer, submucosal layer, mucsularis layer, and serosa layer. Further, EUS was able to distinguish the mucosal surface layer and the mucosal layer in the mucosal layer. The total of mucosal and submucosal layers measured by AUS was 0.4 mm thicker than that measured by radial EUS (p<0.05). There was also a correlation between body weight and the total thickness of the mucosal and submucosal layers (p<0.0001, r=0.67). Therefore, when using radial EUS, it is necessary to consider the difference of thickness, and accordingly a new reference value should be determined on basis of body weight. In the future, specific changes in the mucosal structure of gastrointestinal diseases might be observed more closely by radial EUD.

    Extended-spectrum β-lactamase(ESBL)-producing Klebsiella pneumoniae, a bacterium newly resistant to many kinds of β-lactams, has caused serious problems in humans, but no canine data on ESBL-producing K. pneumoniae are available in Japan. A ten-year-old, castrated Shih Tzu was suffering from intractable cystitis infected with ESBL-producing K. pneumoniae after removal of urinary bladder stones. Administration of doxycycline, amoxicillin-clavulanic acid, trimethoprim- sulfamethoxazole, or amikacin was not very effective, but oral administration of faropenem, a penem antibiotic, was effective. The dog made a complete recovery. We need to take precautions against the future prevalence of ESBL-producing bacteria in hospitals.

    Echocardiography was performed on a 4-year-old, mixed-breed cat with pleural fluid. Severe enlargement of the right atrium and ventricle, tricuspid regurgitation, a shortened septal leaflet, shortened chordate tendineae, paradoxical septal motion, and amorphous images within the right atrium and ventricle were observed. Judged by the abnormal appearance of the tricuspid, the disease was diagnosed as tricuspid valve dysplasia. Despite treatment with benazepril, pimobendan, furosemide, spironolactone, and dalteparin, the cat's condition worsened, and it died on day 14.

    The aim of this experiment was to evaluate to what degree bentonite was able to suppress cesium (Cs)-transfer to the organs. Six healthy Holstein-Friesian calves were administered cesium chloride (CsCl), a compound of a stable isotopic Cs, with powdered milk solution for 28 days (3.0mg CsCl/kg/day). At the same time, three of the six calves were also given bentonite (0.5w/v %); the other three were used as controls. Blood samples were taken on days 0, 1, 2, 3, 7, 14, 21, and 28 of the experiment, and tissues were collected from the skeletal muscle, heart, liver, kidney, and feces on day 28. The concentrations of Cs in the samples were measured by ICP-MS (inductively coupled plasma mass spectronomy). The average Cs concentration in blood corpuscles from the bentonate group was lower than that of the control group until day 14, although the concentrations in the tissues of the above organs were not clear. This suggests that bentonite may reduce Cs-transfer to the living body.
