An 8-month-old, intact male Maltese dog was referred to us because of anorexia, diarrhea, and jaundice. Hematologic examination revealed immune-mediated hemolytic anemia, and abdominal ultrasonography revealed heterogeneous changes in mesenteric fat and coarse echotexture in the splenic parenchyma. Septic peritonitis was diagnosed on the basis of a bacterial culture test of the peritoneal fluid. Exploratory laparotomy and subsequent omental biopsy and splenectomy were performed. On histopathological examination, the omental mass and splenic lesions were diagnosed as grain foreign body granulomas. This report describes a rare case in which a grain foreign body was embedded in the spleen of a dog.

A 10-year-old male Schnauzer dog presented with a 1-week history of ataxia, right-sided hemiparesis, and right-sided head tilt. On the basis of magnetic resonance imaging (MRI) with neurological examination and cerebrospinal fluid analysis results, a primary brain tumor was suspected. Therapy with imatinib mesylate plus hydroxyurea for 7 weeks was not effective and clinical signs worsened. Chemotherapy was then changed to lomustine plus hydroxyurea. Although the existing clinical signs continued, they did not deteriorate. No change in mass size was observed in subsequent MRI. The subject suddenly died from dyspnea 388 days after initial presentation. In this case, choroid plexus papilloma was definitively diagnosed based on histopathological findings.

The purpose of this study was to investigate whether sporulated Neospora caninum oocysts, which had been stored for 46 mo in a 2% sulfuric acid solution at $4^{\circ}C$, remain morphologically viable and infective to gerbils (Meriones unguiculatus). Six gerbils were orally inoculated with doses of 400 or 1,200 oocysts. Two mo after inoculation, the animals did not show any clinical signs, had no histological lesions, and were seronegative for N. caninum at 1:50 in an immunofluorescent antibody test. PCR using the brain from each gerbil did not reveal N. caninum specific DNA. We conclude that oocysts preserved for 46 mo are not infective, despite being morphologically intact.

Hyaluronic acid (HA) has long been studied in diverse applications. It is a naturally occurring linear polysaccharide in a family of unbranched glycosaminoglycans, which consists of repeating di-saccharide units of N-acetyl-D-glucosamine and D-glucuronic acid. It is almost ubiquitous in humans and other vertebrates, where it participates in many key processes, including cell signaling, tissue regeneration, wound healing, morphogenesis, matrix organization, and pathobiology. HA is biocompatible, biodegradable, muco-adhesive, hygroscopic, and viscoelastic. These unique physico-chemical properties have been exploited for several medicinal purposes, including recent uses in the adjuvant treatment for chronic inflammatory disease and to reduce pain and accelerate healing after third molar intervention. This review focuses on the post-operative effect of HA after third molar intervention along with its various physio-chemical, biochemical, and pharmaco-therapeutic uses.

A 7-year-old, male Maltese dog with a body weight of 2.8 kg was presented with a history of hind limbs ataxia that progressed to tetraparesis over a one-month period. Based on physical and neurological examinations, tetraparesis with concomitant UMN signs, kyphosis and severe neck pain were identified. On MRI scan, we tentatively diagnosed this patient as a primary intramedullary spinal cord tumor. Therapy with lomustine plus hydroxyurea and prednisolone was initiated and the clinical signs rapidly improved. The patient was regularly checked by MRI scan and the range of the mass was gradually reduced to complete remission for 11 months. About 19 months after treatment, the patient showed anemia and hematochezia which suspected as adverse effects of chemotherapy. The condition was getting worse over 2 months and the patient suddenly expired 657 days after initial presentation. On histopathological examination, the spinal cord sample was identified as a neuronal atrophy without evidence of tumor cell.

Purpose: Intestinal parasitic infections (IPIs) are a major health problem worldwide, especially in developing countries. According to the literature, children are more likely to get infected due to more frequent exposure to sources of infection. Methods: In this study, we collected 500 fecal samples from children under 15 years of age who referred to labs in Ilam city. All samples were microscopically examined using formalin-ether concentration and Trichrome staining techniques. The results were analyzed using SPSS 20.0. Results: Among 500 investigated samples, 4 types of parasites were detected. Giardia lamblia, Entameba coli, and Blastocystis hominis were identified as intestinal protozoa, and pinworm as intestinal worm. In this study, 23 cases (4.6%) had parasitic infections. 13 patients (2.6%) were infected with Giardia parasite, 4 patients (0.8%) with E. coli, 3 patients (0.6%) with B. hominis and 3 patients (0.6%) had pinworms. Conclusions: The findings of this study showed that the prevalence of IPIs among children aged under 15 years in Ilam is relatively down, which can be attributed of sufficient information of parents and children about the modes of parasite transmission and the important role of carriers in the pathogen cycle.

A 6-year-old, spayed female Cocker Spaniel was presented with generalized seborrhea sicca. Initially gallbladder mucocele (GM) was suggested by high liver enzyme activities and a stellate pattern in ultrasonography. There were no responses during 16 months of medical treatments for GM. Hormonal assay and histopathological findings were consistent with a diagnosis of hypothyroidism. Levothyroxine therapy led to rapid resolution of dermatologic, serum chemical and ultrasonographic abnormalities. This report describes serial changes of skin lesions, serum chemistry and ultrasonography in a dog with concurrent GM and hypothyroidism following treatment of hypothyroidism.

Background: MiRNAs, small non coding RNAs, play a role in the regulation of hematopoiesis, with effects on cell growth, differentiation, and apoptosis. In addition, MiRNAs are thought to play an important role in tumorigenesis. The miR146a G>C polymorphism can lead to alteration of miR146 expression, which appears to be associated with development and progression of several cancers. This study aimed to investigate the association of the miRNA146a (rs2910164) G>C polymorphism and susceptibility to childhood acute lymphoblastic leukemia (ALL) and clinical outcomes. Materials and Methods: Totals of 100 childhood ALL patients and 200 healthy children were studied for miR146a polymorphisms using polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP). Results: The frequency of the miR146a G allele in controls was 0.40 compared with 0.38 in ALL patients. There was no association between miRNA146a (rs2910164) G>C polymorphism and susceptibility to childhood ALL (OR=1.484, 95%CI=0.712-3.093, p=0.290). Moreover, the frequencies of miR146a (rs2910164) G>C polymorphism were not associated with demographic data and clinical outcomes in ALL cases. Conclusions: The miRNA146a polymorphism was not significantly associated with susceptibility to Thai childhood ALL or any clinico-pathological variables.

Lactose synthase catalyses the formation of lactose which is the major osmole of bovine milk and regulates the milk volume. Alpha-lactalbumin (${\alpha}$-LA) is involved in the synthesis of lactose synthase in the mammary gland. Therefore ${\alpha}$-LA is regarded as a plausible candidate gene for the milk yield trait. To determine whether ${\alpha}$-LA is associated with milk performance traits, 1,028 Chinese Holstein cows were used to detect polymorphisms in the ${\alpha}$-LA by means of single-strand conformation polymorphism (SSCP). Two nucleotide transitions were identified in the 5'flanking region and intron 3 of ${\alpha}$-LA. Associations of such polymorphisms with five milk performance traits were analyzed using a general linear model procedure. No significant associations were observed between these polymorphisms and the five milk performance traits (p>0.05). RH mapping placed ${\alpha}$-LA on BTA5q21, linked most closely to markers U63110, CC537786 and L10347 (LOD>8.3), which is far distant from the region of the quantitative trait locus (QTL) on bovine chromosome 5 for variation in the milk yield trait. In summary, based on our findings, we eliminated these SNPs from having an effect on milk performance traits.

A 7-year-old, intact female Yorkshire terrier dog was presented for coughing, anorexia, chest pain and dyspnea. Right lateral thoracic radiograph demonstrated a large mass shape on the heart base with decreased cardiac silhouette and severe right deviation of the trachea with the heart shifted to the left thoracic wall was observed on the ventrodorsal thoracic projection. Echocardiographic examination revealed a large rounded mass compressing left atrium around the heart base without signs of pericardial effusion. On computed tomographic (CT) findings, sagittal CT images depicted the possibility of cranial vena caval invasion and heart base involvement of the mass associated with biatrial compression. Dorsal CT image revealed the right deviation of trachea due to the heart base mass and markedly shrunk lung space was detected on the transverse CT image. Because the dog suddenly had died during the recovery from anesthesia after finishing CT scan, necropsy was performed. On gross findings, a large and lobulated mass was located at the base of the heart. A poorly-demarcated, infiltrative, multilobulated tumor composed of polyhedral cells in solid cellular sheets was confirmed based on histopathologic examination. This dog was diagnosed as a chemodectoma. This case report describes the clinical findings, diagnostic consistency of thoracic radiography, echocardiography and CT, and histopathologic confirmation in a spontaneously occurring chemodectoma with a Yorkshire terrier dog.
