In this study, we attempted to clarify whether puppy socialization and command training class, which was limited to puppies approximately 4 months of age, prevented behavior problems in dogs. We evaluated the behaviors of 142 dogs with 4 types of training experience by using a behavior test and the Canine Behavior Assessment and Research Questionnaire (C-BARQ). Dogs in the puppy class (PC) group (n=44) attended the class for 1 hr each week for 6 weeks, dogs in the puppy party (PP) group (n=39) attended a 1-hr “puppy party,” dogs in the adult class (AC) group (n=27) undertook basic obedience lessons for adolescent/adult dogs for 1 hr each week for 6 weeks, and dogs in the no class (NC) group (n=32) underwent no formal training. The behavior test evaluated each dog‘s response to commands, owner‘s recall, separation, a novel stimulus, and strangers. The C-BARQ evaluated 15 canine behavioral factors. The behavior test results indicated that the PC and AC groups showed significantly higher response to commands than the PP or NC group. Thus, participation in puppy and adult classes improved the obedience behavior of dogs, regardless of age. Positive response to strangers in the PC group was significantly higher than that in the AC and NC groups and tended to be higher than that in the PP group. Therefore, PC may help prevent canine behavioral problems such as disobedience or fear of strangers.

Methylglyoxal (MGO) is a metabolite of glucose and likely related to pathogenesis of diabetes-related vascular complications including hypertension. In this study, long-term effects of MGO on endothelial function were examined. Rat isolated mesenteric artery was treated for 3 days with MGO using an organ culture method. The contractility, morphology, and protein expression of organ-cultured artery were examined. MGO (42 μM, 3 days) impaired acetylcholine (ACh: 1 nM–300 μM)-induced endothelium-dependent relaxation, while it had no effect on sodium nitroprusside (0.1 nM–10 μM)-induced endothelium-independent relaxation. MGO decreased ACh (3 μM)-induced nitric oxide (NO) production as measured by a fluorescence NO indicator, diaminofluorescein-2. Consistently, MGO inhibited ACh (3 μM)-induced phosphorylation of vasodilator stimulated phosphoprotein (an indicator of cyclic GMP production). MGO induced apoptosis in endothelium as detected by TdT-mediated dUTP-biotin nick-end labeling staining. MGO induced accumulation of superoxide in endothelium as detected by dihydroethidium staining. MGO decreased protein expression of endothelial NO synthase (eNOS). Gp91ds-tat (0.1 μM), an inhibitor of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase (NOX), prevented the impairment of endothelium-dependent relaxation and the decrease in eNOS protein caused by MGO. The present results demonstrated that long-term MGO treatment impairs endothelium-dependent relaxation through NOX-derived increased superoxide-mediated endothelial apoptosis.

We report two feline cases of patent ductus arteriosus (PDA) with pulmonary hypertension (PH). The subjects were both intact domestic shorthair cats, a 4-month-old, 2.5 kg male (case 1) and an 8-month-old, 2.12 kg female (case 2). At the first presentation, left-sided congestive heart failure was diagnosed in case 1 and severe aortic stenosis (AS) in case 2. Following surgical ligation of the ductus arteriosus (DA), furosemide therapy was no longer required in case 1, and the severe AS improved to mild status in case 2 perhaps because of reduced volume overload. In case 2, severe hypoxemia was revealed after surgery; however, this normalized within 96 days after surgery.

The objective of this study was to evaluate glomerular filtration rate (GFR) and the cardiovascular effects of the combination of tepoxalin (TPX) and medetomidine (MED) in dogs. Six healthy dogs of either sex (5 males, 1 female), aged 2.5 ± 2.2 years and weighing 14.7 ± 4.4 kg, were studied. Each dog received four randomized treatments with a minimum of 1 week between treatments: no medication as the control group (C); MED (750 μg/m2, intravenously [IV]); TPX (10 mg/kg orally for 3 days); and MT (TPX 10 mg/kg orally for 3 days plus MED 750 μg/m2, IV). Iohexol (300 mg iodine/kg, IV) was injected in all dogs in each treatment as an indicator of GFR. Blood samples for serum iohexol clearance analysis were collected before and 1, 2, 5, 10, 15, 20, 60, 120, 240, and 360 min after the iohexol administration. Rectal temperature, heart rate, respiratory rate, and direct arterial pressure (AP) were obtained before and 5, 10, 15, 20, 60, 120, 240, and 360 min after the iohexol injection. GFR did not differ between treatments. Heart rate was significantly lower in the MED and MT groups than in C or TPX. Mean AP was significantly higher with MT than TPX, but only at 5 min after the iohexol injection. TPX, MED and the combination of these two drugs do not alter GFR. The combination has minimal effect on cardiovascular variables at these doses in healthy dogs.

Monocyte chemoattractant protein-1 (MCP-1) is a member of the C-C family chemokines, which mobilizes monocytes from bone marrow to the site of inflammation. To evaluate the clinical utility of canine MCP-1 as a blood test item, we measured serum MCP-1 concentrations in normal and ill dogs. Reference interval of canine MCP-1 was established as 115.6–176.9 pg/ml. Serum MCP-1 concentrations increased in the dogs affected with neoplastic (518.0 ± 84.8 pg/ml), inflammatory (257.0 ± 42.5 pg/ml) or other diseases (360.3 ± 45.2 pg/ml). The results showed high sensitivity of MCP-1 to detect neoplasia and inflammation. Moreover, MCP-1 increased in some cases in which C-reactive protein didn’t increase. MCP-1 might be helpful as a screening blood test marker for detection of neoplasia and inflammation in dogs.

The association of renin and angiotensin II, which are potent components of the renin-angiotensin system, with the severity of chronic renal disease was investigated immunohistochemically in dogs and cats. Immunoreactivities of renin and angiotensin II were evaluated quantitatively, and their correlations with the degrees of glomerulosclerosis, glomerular hypertrophy, interstitial cell infiltration, and interstitial fibrosis were statistically analyzed. Immunoreactivities for renin were detected in afferent arteries in both dogs and cats. The score of renin-positive signals showed no correlation with plasma creatinine concentration or any of the histopathological parameters, except for the diameter of glomeruli in dogs. Immunoreactivities for angiotensin II were detected in tubules (primarily proximal tubules) and interstitial mononuclear cells in both dogs and cats. The score of tubular angiotensin II correlated with glomerulosclerosis and cell infiltration in cats but not in dogs. The score of interstitial angiotensin II correlated with plasma creatinine concentration, glomerulosclerosis, cell infiltration, and fibrosis in dogs and with glomerulosclerosis and cell infiltration in cats. In conclusion, the results of the study suggest that intrarenal renin-angiotensin system is correlated with the severity of kidney disease, with the underlying mechanism differing between dogs and cats.

A 13-year-old, neutered male miniature dachshund was presented with a one-month history of bilateral symmetrical swelling in the pinnae and carpal, cubital, and tarsal joints, and swelling in the tail. The lesions were histopathologically characterized by multiple dilated lymphatic vessels lined by a single attenuated layer of endothelial cells. The subcutis was predominantly involved. A number of spindle-shaped cells lining the irregular vessels were observed. Morphological atypia was not evident in these cells. Immunohistochemical analyses revealed that the proliferating endothelial cells were positive for factor VIII-related antigen and CD31. Based on the clinical presentation and histopathological features, the dog was diagnosed with lymphangiomatosis. Treatment with anti-inflammatory prednisolone improved the symptoms.

Monitoring of blood glucose concentration is important to evaluate the diabetic status of dogs. Continuous glucose monitoring systems (CGMS) have been applied in veterinary medicine for glucose monitoring in diabetic dogs. The purpose of the study was to evaluate the daily glycemic profiles obtained with CGMS and compare glucose fluctuations between day- and night-time in diabetic dogs. Five diabetic dogs were used in this study and were treated with either NPH insulin or insulin detemir. For data analyses, day-time was defined as 9:00am–9:00pm and night-time as 9:00pm–9:00am. Using glucose profiles, we determined the mean glucose concentrations (1- and 12-hr intervals), and times spent in hyperglycemia >200 mg/dl or hypoglycemia <60 mg/dl. None of the parameters differed significantly between day-time and night-time in dogs treated with NPH insulin or insulin detemir. In conclusion, this study confirmed, using CGMS, that there are no differences in glucose fluctuations between day- and night-time, in diabetic dogs on a similar feeding regimen and insulin administration.

Narrow-band UVB (NB-UVB) is light over a very narrow band of wavelengths (around 311 nm) that is concentrated in the therapeutic range and minimally in the sunburn range. It has therefore become the phototherapy treatment of choice for skin diseases. The minimal erythema dose (MED) on canine skin for standardizing dosage schedules in NB-UVB treatment and histopathological analyses were performed in these dogs. In all 32 dogs tested, the MED ranged from 432 to 864 mJ/cm2. There were no significant differences in MED among breeds, sex and age groups. Histopathology obtained from areas irradiated by MED showed only mild vascular dilatation. These findings might be valuable for the application of NB-UVB phototherapy to canine skin diseases.

Mitral valvuloplasty (MVP) is used in dogs with refractory mitral regurgitation (MR); however, it is difficult to tie the artificial chord, i.e., the expanded polytetrafluoroethylene suture, at the planned height of the mitral valve because of the slippery nature of the knot. The loop technique has resolved these difficulties in humans. Premanufactured loops (length, 8.0–15.0 mm with 1.0-mm increments) were used in the new modified loop technique. In the current study, cardiac murmurs disappeared, and the MR markedly improved or completely disappeared approximately 3 months after surgery in 3 dogs. Therefore, this new technique might be effective in dogs.

Guide dogs help visually impaired persons both physically and psychologically. More than half of all candidate dogs do not qualify, mainly for behavioral reasons. Improved training efficacy is desirable, and earlier prediction of qualification-related traits would be beneficial. In a previous study, we identified ‘Distraction’, assessed during the training period, as an important behavioral trait for judging the qualification of guide dogs at the Japan Guide Dog Association. As a second step, we aimed to develop an index that can predict during the puppy period. In this study, candidate guide dogs, 5-month-old Labrador retrievers, were assessed by puppy raisers using a newly developed questionnaire that consisted of 20 items. The same dogs were assessed later, at 15 months, by trainers to determine ‘Distraction’. In principal components analysis, 9 items, including excitability toward strangers, initiative while out for a walk, and exploration, composed the first principal component (PC1). When we compared PC1 points with ‘Distraction’ points, the two categories were positively correlated (n=110, rs=0.31, P=0.0009). Although the accuracy of the questionnaire should be increased, the results of the present study suggest that it may be possible to assess and predict ‘Distraction’, which is associated with disqualification for guide dogs, early in the puppy-raising period.

A multiplex reverse transcription polymerase chain reaction (mRT-PCR) assay was developed for the simultaneous detection of canine distemper virus (CDV), canine respiratory coronavirus (CRCoV), and canine influenza virus (CIV). These viral pathogens are all causative agents of canine infectious respiratory disease (CIRD). The sensitivity and specificity of the mRT-PCR were determined by comparing it to a rapid antigen test (RAT) or immuno-chromatography test kit and reverse transcription-polymerase chain reaction (RT-PCR) in the detection of CDV, CRCoV, and CIV antigens present in 100 clinical samples (nasal swabs and whole blood samples) from 50 dogs with respiratory disease symptoms. This study revealed that mRT-PCR had almost exactly the same performance or results were almost 100% in agreement with that of RT-PCR and RAT both in terms of the assay sensitivity and specificity which was more highly evident in detecting CIV, CDV, and CRCoV antigens present in canine nasal swab samples. Therefore, this assay could be a better alternative for the definitive and simultaneous ante-mortem detection of the three viral pathogens that cause CIRD by using nasal swabs.

A one-month male Greyhound dog presented with a swinging gait of the hindlimbs, and later developed muscular atrophy of the femoral region and hyperextension of hindlimbs. The dog had positive serum IFAT titers to Neospora caninum, but a negative titer in the cerebrospinal fluid (CSF). N. caninum-specific DNA was amplified from the CSF using a semi-nested polymerase chain reaction assay. Clusters of protozoa in biopsied muscle fibers were subsequently confirmed as N. caninum tachyzoites by immunohistochemical examination. Early recognition and treatment are necessary for effective recovery of clinical canine neosporosis, but antemortem diagnosis is difficult. We suggest that the detection of parasite deoxyribonucleic acid in the CSF is a useful antemortem diagnostic method in facilitating treatment of this disease.

House dust mite (HDM) allergens are the most common allergens for induction of IgE-mediated hypersensitivity. Recently, epicutaneous sensitization with HDM allergens has been emphasized in the development of atopic dermatitis (AD) by producing various soluble factors in keratinocytes. Among the soluble factors, GM-CSF is a key molecule that activates Langerhans cells, antigen-presenting cells in the epidermis. In the present study, we investigated the effects of Dermatophagoides farinae (Der f) on GM-CSF production in a canine keratinocyte cell line, CPEK. CPEKs were found to produce GM-CSF upon stimulation by Der f. The GM-CSF production was suppressed by addition of a cysteine protease inhibitor. The present results suggest that cysteine protease-derived Der f may be an initiator of allergic inflammation by inducing the production of GM-CSF in keratinocytes.

Extraskeletal myxoid chondrosarcoma was found in a five-month-old male Irish setter dog. At necropsy, the largest mass, measuring 15 × 13 × 13 cm, was found in the right caudal lobe of the lung, and metastatic small masses were observed in multiple organs. Microscopically, the tumor comprised mainly atypical mesenchymal cells and myxoid stroma, which stained positively with Alcian blue. Immunohistochemically, the tumor cells stained positively for vimentin, S-100 protein, neuron-specific enolase, calretinin, and chromogranin A. Ultrastructurally, the cytoplasm of the tumor cells was comprised abundant rough endoplasmic reticulum, mitochondria, Golgi complex, free ribosomes and short irregular microvillous processes extending from the cytoplasm. Based on these pathological findings, this tumor was diagnosed as extraskeletal myxoid chondrosarcoma.

Although the susceptibility of dermatophytes to antifungal drugs is well documented in humans, the effectiveness in animals has not been previously investigated. The in vitro susceptibility of 54 clinical isolates from animal dermatophytoses to ketoconazole (KTZ), itaconazole (ITZ) and terbinafine (TFN) was measured using microdilution assay (CLSI M38-A2 test) and by the E-test (KTZ and ITZ). All 3 drugs showed antifungal activity, while KTZ displayed the broadest minimum inhibition concentration (MIC) range (0.125–16 μg/ml) against M. canis and M. gypseum. The MIC of KTZ and ITZ was almost the same for human and animal isolates of T. mentagrophytes and T. rubrum. The MIC of TFN was almost the same for dermatophytes isolated from humans and animals.

The Food Safety Commission (FSC) of Japan, established in July 2003, has its own initiative to conduct risk assessments on food stuffs known as “self-tasking assessment”. Within this framework, the FSC decided to conduct a risk assessment of beef and beef offal imported into Japan from countries with no previous BSE reports; thus, a methodology was formed to suit to this purpose. This methodology was partly based on the previous assessments of Japanese domestic beef and beef imported from U.S.A./Canada, but some modifications were made. Other organizations’ assessment methods, such as those used for BSE status assessment in live cattle by the OIE and EFSA’s GBR, were also consulted. In this review, the authors introduce this alternative methodology, which reflects (1) the risk of live cattle in the assessed country including temporal risks of BSE invasion and domestic propagation, with the assessment results verified by surveillance data, and (2) the risk of beef and beef offal consisting of cumulative BSE risk by types of slaughtering and meat production processes implemented and the status of mechanically recovered meat production. Other possible influencing factors such as atypical BSE cases were also reviewed. The key characteristic of the current assessment is a combination of the time-sequential risk level of live cattle and qualitative risk level of meat production at present in an assessed country.

Aspergillus udagawae and A. viridinutans are members of the section Fumigati; both cause invasive aspergillosis in humans. These two Aspergillus species are discriminated from A. fumigatus by molecular methods. Herein, we report two cases of feline orbital aspergillosis, one caused by A. udagawae and the other by A. viridinutans. To our knowledge, Case 1 represents the first reported case of treatment of A. udagawae with a high dosage of itraconazole, and Case 2 represents the first reported case of A. viridinutans infection associated with sarcoma. Identification of the etiologic agents of these cases was confirmed by comparative analyses of the sequences of β-tubulin-encoding genes. With the spread of non-fumigatus aspergillosis, increasing emphasis should be placed on molecular identification of the infecting Aspergillus species and the use of in vitro drug susceptibility tests to ensure the selection of appropriate antibiotics.
