A 6-year-old spayed female Jack Russell Terrier presented with a 1-month
history of lethargy, anorexia, vomiting and weight loss. The dog was fed beef and chicken
jerky treats daily in addition to a commercial diet. Laboratory tests revealed azotemia,
hypokalemia, hyperchloremia, metabolic acidosis and glucosuria with normoglycemia. Urine
amino acid analysis showed significant amino acid loss into the urine. Thus, Fanconi
syndrome was diagnosed, and based on the case history and extensive diagnostic testing,
excessive consumption of jerky treats was strongly suspected as the cause. Glucosuria
resolved 7 days after the withdrawal of jerky treats and fluid therapy. Aminoaciduria was
substantially, but not completely, improved 3 months after diagnosis. Mild azotemia
remained, suggesting chronic renal disease. To the best of our knowledge, this is the
first reported case of Fanconi syndrome following the consumption of jerky treats in
Japan. 相似文献

Kabuto Mountain virus (KAMV), the new member of the genus Uukuvirus, was isolated from the tick Haemaphysalis flava in 2018 in Japan. To date, there is no information on KAMV infection in human and animals. Therefore, serological surveillance of the infection among humans and wild mammals was conducted by virus-neutralization (VN) test and indirect immunofluorescence assay (IFA). Sera of 24 humans, 59 monkeys, 171 wild boars, 233 Sika deer, 7 bears, and 27 nutria in Yamaguchi Prefecture were analyzed by VN test. The positive ratio of humans, monkeys, wild boars, and Sika deer were 20.8%, 3.4%, 33.9% and 4.7%, respectively. No positive samples were detected in bears and nutria. The correlation coefficients between VN test and IFA in human, monkey, wild boar, and Sika deer sera were 0.5745, 0.7198, 0.9967 and 0.9525, respectively. In addition, KAMV was detected in one pool of Haemaphysalis formosensis ticks in Wakayama Prefecture. These results indicated that KAMV or KAMV-like virus is circulating among many wildlife and ticks, and that this virus incidentally infects humans. 相似文献

Oncolytic virotherapy is a new strategy for cancer treatment for humans and
dogs. Reovirus has been proven to be a potent oncolytic virus in human medicine. Our
laboratory has previously reported that canine mast cell tumor and canine lymphoma were
susceptible to reovirus. In this study, canine solid tumor cell lines (mammary gland
tumor, osteosarcoma and malignant melanoma) were tested to determine their susceptibility
towards reovirus. We demonstrated that reovirus induces more than 50% cell death in three
canine mammary gland tumors and one canine malignant melanoma cell line. The
reovirus-induced cell death occurred via the activation of caspase 3. Ras activation has
been shown to be one of the important mechanisms of reovirus-susceptibility in human
cancers. However, Ras activation was not related to the reovirus-susceptibility in canine
solid tumor cell lines, which was similar to reports in canine mast cell tumor and canine
lymphoma. The results of this study highly suggest that canine mammary gland tumor and
canine malignant melanoma are also potential candidates for reovirus therapy in veterinary
oncology. 相似文献

Maropitant is a neurokinin 1 receptor (NK1R) antagonist that is clinically used as a new
anti-emetic drug for dogs. Substance P (SP) and its receptor NK1R are considered to
modulate gastrointestinal peristalsis. In addition, SP works as an inflammatory mediator
in gastrointestinal diseases. Aim of this study is to clarify the effects of maropitant on
intestinal motility and inflammation in mice. Ex vivo examination of
luminal pressure-induced intestinal motility of whole intestine revealed that maropitant
(0.1–10 µM) increased frequency of contraction, decreased amplitude of
contraction and totally inhibited motility index in a concentration-dependent manner. We
measured intestinal transit in vivo by measuring transportation of orally
administered luminal content labeled with phenol red. Our results demonstrated that
maropitant (10 mg/kg, SC) delayed intestinal transit. Geometric center value was
significantly decreased in maropitant-treated mice. Anti-inflammatory effects of
maropitant against leukocytes infiltration into the intestinal smooth muscle layer in
post-operative ileus (POI) model mice were measured by immunohistochemistry. In POI model
mice, a great number of CD68-positive macrophages or MPO-stained neutrophils infiltrated
into the inflamed muscle region of the intestine. However, in the maropitant treated mice,
the infiltration of leukocytes was not inhibited. The results indicated that maropitant
has ability to induce disorder of intestinal motility in mice, but has no
anti-inflammatory action in the mouse of a POI model. In conclusion, in mice, maropitant
induces disorder of intestinal motility in vivo. 相似文献
