Contrast-enhanced magnetic resonance (MR) imaging with a new liver-specific contrast agent gadolinium-ethoxybenzyl-diethylenetriamine penta-acetic acid (Gd-EOB-DTPA; EOB·Primovist®) was studied in 14 normal beagles and 9 dogs with focal liver lesions. Gd-EOB-DTPA accumulates in normally functioning hepatocytes 20 min after injection. As with Gd-DTPA, it is(More)
We report herein the case of a 46-year-old man with Dubin-Johnson syndrome (DJS) who was referred to our hospital to undergo a right hepatic lobectomy for hepatocellular carcinoma. His complicated postoperative conjugated hyperbilirubinemia was successfully treated by hemopurification based on the increased level of serum hepatocyte growth factor (HGF). It(More)
L-type amino acid transporter 1 (LAT1), an isoform of amino acid transport system L, transports branched or aromatic amino acids essential for fundamental cellular activities such as cellular growth, proliferation and maintenance. This amino acid transporter recently has received attention because of its preferential and up-regulated expression in a variety(More)
Suplatast tosilate (IPD) is a Th2 cytokine inhibitor that lowers the titer of the IgE antibody through specific inhibition of the production of IL (interleukin)-4 and IL-5 by T cells and inhibits tissue infiltration by eosinophils. In this clinical trial, suplatast tosilate (300 mg/day) was administered orally for 4 weeks to 25 patients (13 patients with(More)

L-type amino acid transporter 1 (LAT1), an isoform of amino acid transport system L, transports branched or aromatic amino acids essential for fundamental cellular activities, such as cellular growth, proliferation and maintenance. LAT1 has recently received attention because of its preferential and upregulated expression in a variety of human tumours which(More)
In human bladder cancer patients, ultrasonography is extensively used not only to identify tumor masses but also to evaluate tumor size, shape, echogenicity, location, and degree of tumor invasion into the bladder wall. The information revealed by ultrasonography delineates the tumor's biological features and facilitates prediction of prognosis. However, in(More)
Porencephaly is the congenital cerebral defect and a rare malformation and described few MRI reports in veterinary medicine. MRI features of porencephaly are recognized the coexistence with the unilateral/bilateral hippocampal atrophy, caused by the seizure symptoms in human medicine. We studied 2 dogs and 1 cat with congenital porencephaly to characterize(More)
Gastrointestinal stromal tumor (GIST), a mesenchymal neoplasm affecting the gastrointestinal tract, shows a variety of clinical behaviors from inactive benign to aggressive malignant in dogs. In this study, the feasibility of using clinically significant ultrasonographic features to predict the metastatic potential of canine GIST was investigated through(More)
To evaluate the relationship among immune status and increased morbidity and mortality, peripheral blood lymphocytes (CD3(+), CD4(+), CD8(+) and CD21(+) cells) from 32 healthy dogs over 8 years of age were analyzed. Twenty-five of the 32 dogs were followed-up for 3 years after the analysis; and 14 dogs were found to be diseased, and nine dogs died. There(More)
