Transcatheter arterial embolization (TAE) and transcatheter arterial chemoembolization (TACE) are standard treatments for advanced hepatocellular carcinoma (HCC) and particularly for unresectable tumors or liver metastases in humans. However, reports on TACE used in veterinary medicine are few. This study aimed to evaluate the feasibility and safety of drug-eluting bead transarterial chemoembolization (DEB-TACE). We performed DEB-TACE in four clinically normal dogs and pharmacokinetically compared the results against hepatic arterial infusion (HAI) of cisplatin in two dogs. Drug-eluting beads (DEB) loaded with cisplatin were injected through a microcatheter for selective embolization of the left hepatic artery. After embolization, computed tomography (CT) images and histological examination findings were obtained during a 4-week observation period. Serum platinum concentrations were measured to evaluate cisplatin after each procedure. Biochemical analysis was performed during a 12-week observation period. Embolization was successful in all dogs, and there were no clinically apparent abnormalities. Embolization was confirmed up to 4 weeks after DEB-TACE in two of the four dogs and up to 1 week in the other two dogs using postoperative CT images. Cisplatin was not detected in peripheral veins in all dogs after DEB-TACE, but it was detected in trace amounts after HAI. DEB-TACE using cisplatin was safe and well tolerated by normal dogs. DEB-TACE may be useful in terms of determining systemic toxicity and drug concentration within tumors.

2003年5月から2005年4月の2年間に, 和歌山県を主体とした関西3府県で駆除された野生化アライグマ555頭について腸管寄生虫を調べた.そのうち61頭から, 鳥類を固有終宿主とする7種の鉤頭虫が検出された.これらは, Centrorhynchus bazaleticus, Centrorhynchus elongatus, Centrorhynchus teres, Sphaerirostris lanceoides, Plagiorhynchus ogatai, Porrorchis oti, Southwelina hispidaの幼鉤頭虫と同定され, これまで日本あるいは極東からは未確認であった3種, すなわちC. bazaleticus, C. teres, S. lanceoidesが含まれていた.幼鉤頭虫のアライグマからの検出は, 春先から初夏にかけて高く(月別検出率8.3-36.8%, 平均21.5%), その他の季節では低かった(同様に0-20.0%, 平均6.3%).このように, 季節によって鉤頭虫検出率が変動する要因は不明である.国内に分布する野鳥の鉤頭虫相やその地理的分布についてはほとんど情報がなく, また, 検査材料調達にも限界があることから, 国内各地で通年的に駆除されるアライグマからの鉤頭虫検出情報に大きな手がかりを期待したい.

Birds of a number of species have died as a result of lead (Pb) poisoning, including many Steller’s sea eagles (Haliaeetus pelagicus) and white-tailed sea eagles (Haliaeetus albicilla) in Hokkaido, the northernmost island of Japan. To address this issue, the use of any type of Pb ammunition for hunting of large animals was prohibited in Hokkaido in 2004. However, Pb poisoning is still being reported in this area, and there are few regulations regarding the use of Pb ammunition in other parts of Japan, where it has been reported that eagles and water birds have been exposed to Pb. This study was performed to accurately determine the current level of Pb exposure of birds found dead in the field or dead in the wild bird centers in Japan (June 2015–May 2018) and to identify the sources of Pb. Pb exposure was found to still be occurring in raptors and water birds in various parts of Japan. Twenty-six point five % and 5.9% of the recorded deaths of Steller’s sea eagles and white-tailed sea eagles, respectively, were found to have been poisoned by Pb. In addition, Pb isotope ratio analysis showed that both Pb rifle bullets and Pb shot pellets cause Pb exposure in birds, and these endangered eagles are also exposed to Pb in Hokkaido due to the illegal use of Pb ammunition. Changing to Pb-free ammunition, such as copper (Cu) rifle bullets, steel shot pellets, or bismuth shot pellets, will be essential for the conservation of avian species in Japan.

A 13-year-old spayed female Cavalier King Charles Spaniel presented with chronic swelling and pruritus on the palmar aspect of the left forepaw and on the tail. Cutaneous epitheliotropic lymphoma (CEL) was diagnosed by histopathology and immunocytochemistry. Prednisolone was initially used alone as an alternative treatment for CEL. Despite long-term corticosteroid therapy, the patient’s physiological (pruritus) and dermatological signs (alopecia, erythema, erosion, and ulceration with crust) progressed and showed no evidence of improvement. To address the worsening condition of pruritus, lokivetmab was started in combination with prednisolone. Once on lokivetmab, the pruritus steadily improved and was effective in resolving and maintaining remission. Further investigation on the critical role of IL-31 in the pruritus pathway of dogs with CEL is required.

高脂質血症と高血圧は, 動脈硬化発症における重要な危険因子として知られている. そして, 心臓血管系機能は自律神経系によって調節されているが, 過度の交感神経系の刺激は血圧の上昇を誘発すると考えられている. 高脂質血症と心臓血管系機能の変化は密接に関わっていると考えられるが, アドレナリン作働薬の心臓血管系反応に及ぼす高脂質血症の影響についてはあまり知られていない. そこで, 本研究では高脂質血症を誘発したブタを使用し, ノルエピネフリンとイソプロテレノールに対する心臓血管系の反応に関して, 対照群と高脂質血症群とを比較した. 対照群と高脂質血症群の薬物投与前における心血行動態パラメーターのコントロール値に, 有意な差は認められなかった. しかしながら, 高脂質血症群は対照群に比べて, ノルエピネフリンの血圧上昇作用は有意に高く, ノルエピネフリンとイソプロテレノールに対する心臓の収縮力は有意に高かった. そして, 血圧上昇に対する反射性徐脈は起こらなかった. これらの結果から, 高脂質血症が, 心臓血管系に対するアドレナリン作働薬の反応を増強していること, 心臓血管系の反射性調節に何等かの影響を及ぼしていることが明らかとなり, 動脈硬化発症の機序において高脂質血症と高血圧の連関が重要な一因を担っているものと考えられた.

In order to examine reproductive characteristics of feral raccoons in Kamakura, 335 raccoons were collected from March 2005 to March 2007. Raccoons were classified into five age classes: Class I, less than 5 months old; Class II, 5-11 months; Class III, 12-17 months; Class IV, 18-23 months; and Class V, over 23 months old. Females were examined for their age specific pregnancy rate and litter size. To determine when raccoon births occur in the region, birth months of fetuses were estimated by the fetal growth rate, and birth months of Class I individuals were examined by tooth eruption. From fetuses of 18 pregnant females and 47 Class I individuals, it was found that the raccoon births occur from February to October. Of 163 females examined, all of Class I-II females were nulliparous. Pregnancy rate was 47.6% in Class III females, which was significantly lower than 75.0% in Class IV and 78.1% in Class V. The litter size of fetuses ranged from 2 to 5, and 3.9 on average; and that of placental scars ranged from 1 to 7, 3.8 on average. Our findings suggest that parturition of raccoons is a bimodal distribution and age at first parturition may occur between 12 and 17 months old. In order to reduce the raccoon population successfully, females of all ages should be captured throughout the year.

飼育下においてニホンザルの身体成長がどのようにまたどこの部位が変化するのかを明らかにするために,放飼場とケージという異なる飼育様式で1歳齢から7歳齢までの,雄77例,雌92例を対象に身体の各部36項目の生体計測を行った.ケージ飼育個体の計測値は多くの項目で放飼場飼育個体の値より小さかった.雌雄ともに初期発達期に成長率が大きい項目で育成空間の大きさの影響を受けやすいことが明らかになった.多くの項目は性成熟期の成長によって初期成長の遅れを回復するが,移動運動に関連する前腕最少周囲径,手長,下腿最少周囲径および足長では発達初期の影響を大きく受け,ケージ飼育個体の成長の遅延したままであった.雌の方が雄よりも飼育スペースの大きさの影響を受けやすいことも明らかになった.これらのことからニホンザルの持っている本来の成長を保証するためには,面積が広く且つ垂直方向に自由に運動できる飼育環境が必要であることが示唆された.

すべてのネコはRD114ウイルスという感染性の内在性レトロウイルスをもっている。ネコの細胞を製造に用いた弱毒生ワクチンには、RD114ウイルスが迷入する可能性がある。ネコ用ワクチンにおけるRD114ウイルスの迷入を調べるために、今回我々はLacZ遺伝子をマーカーとしたマーカーレスキューアッセイを開発した。調べた4種類のヒト由来株化細胞(TE671細胞、HeLa細胞、293T細胞、HT1080細胞)のうち、TE671細胞(ヒト横紋筋肉腫由来細胞)がRD114ウイルスにもっとも感受性が高く、また同細胞においてウイルスが効率よく増殖した。RD114ウイルスの感染は、ウイルス吸着時にpolybreneを2μg/mlから8μg/ml添加することにより約5倍増大した。最大のウイルス力価を得るためのウイルス吸着時間は4時間で十分であった。LacZ遺伝子を導入したTE671細胞に階段希釈したRD114ウイルスを接種したところ、限界希釈したサンプル(すなわち10感染ユニット未満)において、ウイルス接種後12日後にLacZマーカーレスキューアッセイによりウイルスの検出ができた。今回得られた結果をもとに、感染性のRD114ウイルスを検出するLacZマーカーレスキューアッセイの標準法を提唱する。

Although Toxoplasma gondii represents an oft-cited cause of myocarditis in veterinary medicine, the existing literature on the pre-mortem demonstration of T. gondii-associated myocardial injury (MI) in dogs is scant. In this case series, we provide detailed clinical, laboratory, echocardiographic and electrocardiographic description of three T. gondii-positive dogs diagnosed with MI. In all cases, etiological diagnosis was based on the antibody screening test (all dogs had IgM titres ≥1:64) and MI was demonstrated by a concomitant increase of the serum concentration of cardiac troponin I (0.25–9.6 ng/ml, upper hospital limit <0.15 ng/ml). In all dogs, MI was aggravated by complex arrhythmias (ventricular in two dogs, and either ventricular and supraventricular in the remaining dog). In one case, left ventricular systolic dysfunction was also present. All dogs underwent an extensive diagnostic work-up aimed at excluding additional comorbidities, either cardiac and extra-cardiac, possibly able to contribute to MI, arrhythmias and systolic dysfunction. All dogs received appropriate antiprotozoal (i.e., clindamycin) and antiarrhythmic (i.e., amiodarone, sotalol) therapy. This was systematically followed by a simultaneous decline in T. gondii serology titres, normalisation of troponin level and left ventricular systolic function, and the resolution of clinical and electrocardiographic abnormalities. In light of this result, therapies were interrupted and subsequent controls ruled out any disease relapse. In these cases, the clinical and instrumental findings obtained at admission and rechecks strongly supported the clinical suspicion of toxoplasmic myocarditis.

An 8-year 8-month-old castrated male Munchkin presented with vomiting, anorexia and hypoactivity. Computed tomography revealed excessive gas accumulation within the intestinal lumen and gas bubbles in the liver, spleen, and portal venous system, indicating hepatic portal venous gas. The cat died without any significant improvement, and mild splenomegaly was found at necropsy. Histologically, multiple gas vacuoles were diffusely observed in the liver and spleen. In the stomach, multiple gas vacuoles and scattered focal ulcers were detected within the mucosa. Multifocal hemorrhage was noted in the small and large intestines, whereas gas vacuoles were not present. Based on these findings, a gastric ulcer under high gas pressure may have provided an entry point for gas into the portal venous system.

Larva migrans caused by the common raccoon ascarid, Baylisascaris procyonis, is a zoonotic disease of critical importance in North America. Recently we encountered the first proven outbreak of this disease in Japan in domestic rabbits (Oryctolagus cuniculus) in a small wildlife park. In this park, raccoons (Procyon lotor) had been kept for 9 years, and one raccoon was donated to the park by a pet owner 8 weeks prior to the occurrence of an outbreak in rabbits. Of 12 total raccoons, three raccoons including the donated one shed B. procyonis eggs in the feces, and two of these positive raccoons were kept in metal mesh cages on wooden pedestals, 2 m distant from the rabbit enclosure. Circumstantial evidence indicates that the donated raccoon is the likely source of this outbreak. Treatment of the raccoons with an ascaricide and decontamination by extensive flaming of the cages and the contaminated dirt floor of the park achieved a transient disappearance of ascarids from all 12 enclosed raccoons. Three months after the control measures began, recurrent ascarid infection was detected in three young raccoons of less than 1.5 years of age. The potential risk of serious zoonosis by B. procyonis as well as the difficulty in a clearance of contaminated areas should be considered by pet owners and public health workers in Japan.

A 10-year-old spayed female Golden Retriever was referred for hindlimb lameness. A firm mass was palpated over the right caudal pelvis. Computed tomography revealed an osteolytic bone region and an associated periosteal reaction in the ischium, including the acetabulum. The histological diagnosis was sarcoma of unknown origin. A mid-to-caudal partial hemipelvectomy was performed to remove the mass. Femoral head and neck osteotomy was performed to allow hindlimb preservation. Following surgery, the dog regained satisfactory hindlimb use over time and was alive for 821 days with no recurrence or metastatic disease. This report indicates that mid-to-caudal partial hemipelvectomy with femoral head and neck osteotomy is technically feasible and allows for tumor control with preservation of the hindlimb and its function.

In this experiment, we studied the effects of breed differences in intramuscular adipogenic capacity on the metabolomic profiles of plasma and intramuscular adipose tissue between Wagyu (high intramuscular adipogenic capacity) and Holstein (low intramuscular adipogenic capacity) using capillary electrophoresis time-of-flight mass spectrometry (CE-TOFMS). We showed that the intramuscular fat content, intramuscular adipocyte size and the expression of adipogenic transcription factor (C/EBPβ and C/EBPα) of Wagyu were significantly higher than those of Holstein. Metabolites detected at significantly higher levels in Wagyu plasma were related to the tricarboxylic acid cycle, lipid synthesis, fatty acid metabolism, diabetes, and glucose homeostasis. In contrast, metabolites detected at significantly higher levels in Holstein plasma were related to choline metabolism, the ethanolamine pathway, glutathione homeostasis, nucleic acid metabolism, and amino acid metabolism. Metabolites detected at significantly higher levels in Holstein intramuscular adipose tissue were related to nucleic acid metabolism, amino acid metabolism, amino sugar metabolism, beta oxidation, and the ethanolamine pathway. There were no metabolites significantly higher levels in Wagyu intramuscular adipose tissue. These results indicate candidate biomarkers of breed differences in intramuscular adipogenic capacity between Wagyu and Holstein.

A 1-year-old domestic shorthair cat was evaluated for a chronic history of back pain, dysuria, and paraplegia. Radiographic and computed tomographic examinations showed circumferential widening of the vertebral canal at T13 and T14. A spinal epidural abscess (SEA) compressing the spinal cord from the level of T11 to L1 was suspected following intravenous contrast administration, and was confirmed by surgical exploration and histopathological analysis. The cat recovered its motor and bladder functions following surgical decompression and antibiotic therapy. SEA is a neurological emergency requiring prompt treatment. However, the present case had a prolonged disease course and pressure atrophy of the vertebrae was strongly suspected. To our knowledge, this imaging finding has not been reported in dogs or cats with SEA.

C-C chemokine receptor 7 (CCR7) contributes to cell homing to lymph nodes (LNs). Recent studies reported that CCR7 is also expressed in tumor cells, which correlates with LN metastasis in various cancers. However, the expression of CCR7 in tumor cells is unknown in dogs due to the lack of appropriate antibodies. In the present study, a fusion protein of C-C chemokine ligand 19 (CCL19) was employed as an alternative method to CCR7 antibodies. The fusion CCL19 protein specifically detected CCR7 expressed in canine lymphoma cell lines, which showed active chemotaxis to both canine and mouse ligands. The present study will help further research on the involvement of canine CCR7 in LN metastasis.

A 5-year-old female cat with nonregenerative anemia and thrombocytopenia was diagnosed with myelodysplastic syndromes (MDS), since peripheral blood and bone marrow (BM) examination revealed various dysplasias and a blast ratio of 19%. Chemotherapy with azacytidine (AZA; 70–35 mg/m2, 3–5 days, three cycles) and treatment with prednisolone, antibiotics, and vitamin K2, and blood transfusion were performed. On day 106, blast cells and dysplasia had decreased in the BM, and the cat remained alive for at least 1,474 days. This report is the first on feline MDS treated with AZA, suggesting appropriate drug dosage, interval and effective combination should be investigated and the pharmacological and cell biological mechanisms needs to be elucidated in the future.

The rabies virus is one of the most neurotropic of all viruses infecting mammals. During the terminal phases of infection, the virus spreads to peripheral tissues, including the skin. The external skin of the nose, called the nasal planum, is a sensory organ where numerous nerve bundles and terminal nerves are distributed. Therefore, the nasal planum is expected to serve as a postmortem diagnostic material. However, the distribution of rabies virus antigens in the nasal planum in rabid animals has not yet been studied. In this study, the nasal planum was obtained from 45 rabid dogs. In all rabid dogs, the viral antigen was detected in the peripheral nerve tissues, Merkel cells, and squamous cells. The viral antigen in the epidermis exhibited three patterns: first, a diffuse positive pattern from the basal layer to the squamous layer; second, a reticular positive pattern along the cell membrane in the squamous layer; and third, a basal layer pattern of the epidermis. In the dermis, viral antigens were detected more often in lamellated corpuscles just beneath the rete pegs. These results suggest that the nasal planum could serve as a useful alternative source for postmortem diagnosis in rabies endemic countries.

Severe adverse reactions in cats after vaccination were examined from 316 cases reported to the Ministry of Agriculture, Forestry and Fisheries (MAFF) in Japan during 15-year period from April 2004 to March 2019. We found that 130 (41%) showed anaphylaxis, and 99 (76%) of the 130 cases of anaphylaxis resulted in death. Veterinarians should be well prepared to deal with vaccine-associated anaphylaxis in cats. Bovine serum albumin (BSA) as indicator of purification was detected at high levels in commercially available feline vaccines. BSA might derive from fetal calf serum in culture media. This study provides useful information about anaphylaxis including critical details of the potential clinical signs associated with adverse events to feline vaccination.

Podoplanin is expressed in various human tumors where it promotes tumor progression, epithelial-mesenchymal transition, and distant metastasis. Podoplanin is also expressed in cancer-associated fibroblasts and induces tumor malignancy. The objective of this study was to evaluate podoplanin expression in various types of feline tumor tissues. Immunohistochemical analysis revealed that podoplanin was expressed in cells of 13/15 (87%) squamous cell carcinomas and 5/19 (26%) fibrosarcomas. Moreover, cancer-associated fibroblasts expressed podoplanin in most tumor types, including 18/21 (86%) mammary adenocarcinoma tissues. Our findings demonstrate that various types of feline tumor tissues expressed podoplanin, indicating the importance of the comparative aspects of podoplanin expression, which may be used as a novel research model for podoplanin biology.

Intestinal lymphangiectasia (IL) is a common complication in dogs. Since nitric oxide (NO) is known to relax the lymphatic duct, we evaluated inducible NO synthase (iNOS) expression using immunohistochemistry in 13 dogs with lymphoplasmacytic enteritis (LPE) with or without IL. The duodenal iNOS expressing cells were significantly increased in dogs with IL-negative or IL-positive LPE dogs (P=0.025, P=0.007) compared with control dogs. However, there was no significant difference in iNOS expression between IL-positive and IL-negative tissues. Based on these results, there is no clear evidence for the NO overproduction in the pathogenesis of IL in dogs with LPE. Factors other than NO could, thus, contribute to IL in dogs with LPE.
