The purpose of the present study was to elucidate such a relationship by comparing the indices of obesity, liver function, and hyperlipidemia with & without fatty liver by using data from health check-up for the adult males in a university hospital. Study subjects were 772 adult males of 30 years and over, who underwent health package check-up at the health promotion center of a university hospital. The prevalence rates of fatty liver of study subjects were 25.5%, and this study shows that fatty liver by abdominal ultrasound has a close correlation with indices of obesity(body weight, BMI, body fat, waist to hip ratio, & waist to stature ratio), liver function(AST, ALT,& GGT), and hyperlipidemia(TG, TC, & HDL-C), and that was independent of age that was relevant.

Insulin resistance plays a central role in fatty liver, a part of the metabolic syndrome. This study examined the relationship between fatty liver, metabolic abnormalities and mitochondrial DNA [mtDNA] copy number in peripheral blood that is correlated with diabetes or metabolic markers. Fatty liver was assessed by questionnaire on alcohol consumption and abdominal ultrasonography. MtDNA copy number in peripheral leukocytes was measured by a real-time quantitative polymerase chain reaction [PCR]. Among 445 subjects, 148 subjects had hepatic steatosis and 297 were controls. mtDNA copy number was significantly lower in fatty liver group in comparison with that of normal finding group. This result is similar in both groups, alcoholic or non-alcoholic fatty liver group. MtDNA copy number was inversely correlated with alanine aminotransferase [ALT], aspartate aminotransferase [AST], gamma-glutamyltransferase [$\gamma$-GTP], body mass index [BMI], waist circumference, diastolic blood pressure, and free fatty acid. MtDNA copy number in peripheral leukocytes was associated with fatty liver and insulin resistance related factors.

We present a case of a 47-year-old woman with benign solitary fibrous tumor of the pleura originated in the diaphragm which was discovered incidentally on a chest radiograph. Chest radiograph, sonograph, computed tomographic scan and magnetic resonance image studies proved a well circumscribed and lobulated fibrous tumor of the pleura. During the subsequent right thoracotomy, the tumor was found to be encapsulated and consisted of firm mass. It was connected to the diaphragm with $5{\times}4$cm area by pedicle. Most of the tumor was free of adhesion. It was excised completely together with attached diaphragm. The tumor measured $23.5{\times}13.5{\times}8.0$cm and the pathologic diagnosis was benign solitary fibrous tumor and the attached diaphragm was free of disease.

We analyzed the clinical characteristics and outcome of ileocecal and small bowel intussusceptions (ICI and SBI) in the pediatric patients. From August 2003 to July 2010, 144 children with intussusception were included in this study. We retrospectively reviewed the clinical records and Imaging study findings. A total of 86 children with ICI and 58 children with SBI were diagnosed. Children with SBI were older than ICI ($36.6{\pm}24.6$ months vs. $24.2{\pm}21.6$ months, p=0.002). Typical symptoms such as irritability, abdominal mass, bloody stool were more frequent in ICI than SBI (p<0.05) patients. In the ICI group, intussusceptums were reduced with air reduction (84.5%), surgery (17.4%), and spontaneity (1.2%). All patients in the SBI group were reduced spontaneously. SBI occurred in older age and was reduced spontaneously more frequently than ICI. Conservative management with close observation with follow-up by ultrasonography is recommended for SBI.

A ten-year-old Yorkshire Terrier developed serious abdominal distension and respiratory distress. Radiography and ultrasonography revealed a hyperechoic mass around the aorta that was contiguous with the right atrium and main pulmonary artery. It was resulted in failure of the right side of the heart including tricuspid regurgitation, hepatomegaly with dilation of the hepatic vein and severe ascites due to a large, expansile mass. Computed tomography(CT) identified a large mass originating at the cardiac hilar region and spanning from the cranial vena cava to the caudal vena cava. The tumor had invaded the cranial vena cava, caudal vena cava, heart and pleural wall. A tentative diagnosis of chemodectoma was assigned to the tumor through a fine needle aspiration. This report focuses on the typical features of imaging diagnosis of heartbase tumors by radiography, ultrasonography and CT.

A 6-year-old castrated male domestic short hair cat with the clinical signs of anorexia and vomiting was admitted to the local animal hospital. Abdominal radiography and ultrasonography revealed renomegaly and severe hydronephrosis in the right kidney. Surgically excised right kidney was submitted for diagnosis. On the cut surface, two milky white masses and severe dilation of renal pelvis were observed. Most of the neoplastic masses were composed of uniform well differentiated tubules lined by a single layer of cuboidal to columnar cells and projected papillae into the lumen. The neoplastic cells were strong positive for cytokeratin (CK) MNF116, but negative for CK 7. Based on the clinical and gross findings, histopathology and immunohistochemistry, this case was diagnosed as papillary renal adenoma with hydronephrosis.

Repeated measurements on each variables of interest often arise in bioscience or medical research. We need to account for correlations among repeated measurements to assess the correlation between two variables in the presence of replication. This paper reviews methods to estimate a correlation coefficient between two variables in repeated measurements using the variance-covariance matrix of linear mixed effect models. We analyze acoustic radiation force impulse imaging (ARFI) data to assess correlation between three shear wave velocity (SWV) measurements in liver or spleen and spleen length by ultrasonography. We present how to obtain parameter estimates for the variance-covariance matrix and correlations in mixed effects models using PROC MIXED in SAS.

A 12-year-old Yorkshire Terrier bitch evaluated with vaginal prolapsed and vaginal bleeding. Abdominal sonography and radiography demonstrated abnormal enlargement of uterus in abdominal cavity. The dog had been submitted to the vaginal mass resection and the ovariohysterectomy. In gross examination, the vaginal mass was firm and multiple cysts were detected in both ovaries and uterine horns. In microscopic examination, vaginal fibroma, uteroovarian cystadenocarcinoma were revealed. To our knowledge, this report is a very rare case of multiple complex neoplasms in the genital organs of dog. These findings may contribute to study and enhance the knowledge on genital tumors.

This study was carried out to investigate of the associations of Alcoholic & Nonalcoholic fatty liver disease(AFLD & NAFLD) with metabolic syndrome(MS) defined by IDF criteria. We conducted a cross-sectional study of 799 adult males with alcohol consumption underwent laboratory investigation(control 297, alcoholic 206, nonalcoholic 296). The ultrasound scan of the liver was performed to determine the presence and the severity of FLD. We analyzed the association between the severity of AFLD & NAFLD and MS by logistic regression analysis. The distribution of metabolic syndrome was 7.4%, 48.8%, 34.9% in control, AFLD & NAFLD. The association of blood pressure, glucose, triglycerides, obesity were risk factor in AFLD & NAFLD. According to the severity of FLD, AFLD was significantly increased with MS, Obesity, low HDL-cholesterol. MS, High triglycerides was increased significantly in NAFLD(p<0.05). The prevalence of AFLD & NAFLD was increased with increasing the number of features of metabolic syndrome. This study shows that AFLD & NAFLD was closely associated with MS and its components. The patients of AFLD & NAFLD should managed and monitored to prevent metabolic abnormalities.

A 9-years-old female Collie dog was presented with history of abdominal enlargement, anorexia and constipation. On radiographic and ultrasonographic examinations, intra-abdominal mass was identified. On cytologic findings of the mass, no cancer cell was observed. Exploratory laparotomy was performed to diagnose and remove the mass. A large, single, spheroid mass weighing 9.5 kg ($40{\times}25{\times}18$ cm) was located in the middle section of the right uterine horn. Based on the results of histopathological examination, the mass was diagnosed as a cystic endometrial hyperplasia (CEH). This is rare case of severe focal CEH without pyometra in a bitch.
