This study was performed to clarify the effect of oculo-acupuncture(OA) on change of gastric contraction. Twenty-four clinically healthy mongrel dogs were used and divided into two groups regarding feeding condition; non-acupoint group (n=6) and Stomach/spleen region group (n=6) were stimulated by OA. In addition, 12 dogs were fasted for 24 hrs and divided into two groups; non-acupoint group (n=6) and Stomach/speen region group (n=6) was stimulated by OA. The change in frequency of gastric contraction was measured via abdominal ultrasound before, 0, 30, 60 and 120 minutes after OA. Significant differences were detected at 30 mins (p<0.05), 60 mins (p<0.05) and 120 mins (p<0.01) in the Stomach/speen region group, compared with those of non-acupoint group in feeding condition.

Intussusception is one of the most common cause of bowel obstruction in infant under the two years old, especially in male. Clinical analysis was enrolled on 54 intussusception cases who were diagnosed by ultrasound and treated by non-operative reduction at the Presbyterian Medical Center from June 2005 to May 2007. The results were as follow. 1) There was the most common(40.7%)between thirteen and twenty four months on the distribution of age. Male(72.2%) and female(27.8%) were in the ratio of 2.6:1 on the distribution of gender 2) The frequent symptoms were abdominal pain with grizzle(100.0%), vomiting(66.7%) and diarrhea(33.3%). There was a significant difference among them(p<0.05). There was the most common(46.3%) between 10,000/$mm^3$ and 15,000/$mm^3$ in the result of WBC. 3) 42.6% of patient at a private hospital performed primary care. The treatment after initiating the symptom of intussusception was performed between 6 hrs and 12hrs (37.0%). 4) The most common type and portion of intussusception were ileo-colon(98.1%) and hepatic flexure (68.5%). 5) 88.0% at air reduction and 86.2% at barium reduction were successful. The reduction rate were similar to both techniques. There was no significant difference between them(p>0.05).

A case of bladder prolapse through a patent urachus is reported in a female infant born with a large, red, tubular mass inferior to the umbilical cord. A cystic mass communicating with fetal bladder was detected by prenatal ultrasound performed at $20^{+2}$ weeks of gestation. A fetal MRI was also performed to confirm the diagnosis and to exclude associated fetal anomalies. At $40^{+4}$ weeks, the cystic mass was no longer present and a new small solid mass was noted at the fetal abdominal wall. After birth, a protruded mucosal mass inferior to the umbilical cord was noted, and catheterization confirmed communication between the protruded mass and the urinary bladder. On the second day of life, reduction of the bladder and partial resection of the urachus was performed. A voiding cystourethrogram showed good bladder capacity and no vesicoureteral reflux. The patient voided well and was discharged after 10 days. Here, we present a case of urinary bladder prolapse through a patent urachus, diagnosed by fetal sonography and this is the first case reported that was treated by simple excision without complication.

Diagnostic approaches such as angiography, ultrasound, computed tomography and nuclear magnetic resonance have limitation for contributing to the early clinical diagnosis of atherosclerosis. Recently, $^{99m}Tc-labelled$ low density lipoprotein was developed to detect early atherosclerotic lesion by external imaging with gamma camera. To determine whether $^{99m}Tc-LDL$ scintigraphy can visualize the active atherosclerotic lesion, rabbits were injected with $^{99m}Tc-LDL$, 3 months after feeding dietary fat (lanolin) and we obtained following results. 1) Labelling efficiency of $^{99m}Tc-LDL$ was $79\sim88%$. 2) Biodistribution study of normal rabbits with $^{99m}Tc-LDL$ revealed the high activities in spleen, adrenal gland, liver, kidney which are major organs of high metabolic rate of LDL. 3) Three months after feeding lanolin, serum cholesterol was markedly increased from $74{\pm}17mg/dl$ to $979{\pm}153mg/dl$ and histologic study of aorta after sacrificing the rabbit demonstrated marked atherosclerotic changes. 4) Atherosclerotic lesion of abdominal aorta which was confirmed with histologic study could be demonstrated in $^{99m}Tc-LDL$ scintigraphy after feeding lanolin for 3 months. In conclusion, the results of this preliminary investigation suggest that it may be possible to image active atheromatous lesion with $^{99m}Tc-LDL$. It is anticipated that this promising agent may allow the in vivo monitoring of preclinical atherosclerotic lesions and may be useful to evaluate the metabolic pathway of LDL in humans.

The body of the fat tissue increased in obese represented by risk factors such as cardiovascular diseases, diabetes, metabolic disease and dyslipidemia. Such metabolic diseases and the like of the cardiovascular and cerebrovascular disease, hypertension, dyslipidemia, increase in the adipose tissue of the pancreas is known to be a risk factor of these diseases. Study on the diagnosis and treatment of pancreatic cancer was conducted actively, case studies on pancreatic steatosis is not much. In this study, divided into a control group diagnosed with pancreatic steatosis as a result of ultrasonography to evaluation the physical characteristics and serologic tests and blood pressure and arterial stiffness. The control group and the test pancreas steatosis age and waist circumference, body mass index, total cholesterol, HDL cholesterol, LDL cholesterol, and systolic and diastolic blood pressure, fasting blood glucose, arterial elasticity is higher in pancreatic steatosis. And the lower ankle brachial stenosis and HDL-cholesterol were lower than the normal control group, so the pancreatic steatosis harmful to blood vessels.(P <0.05). The difference between the control group and it was confirmed that the pancreatic jibanggun statistically significant. In conclusion, pancreatic steatosis at abdominal ultrasound can predict the risk of metabolic diseases, and there was a correlation with cardiovascular disease.

The purpose of this study was to evaluate the clinical significance of ultrasonographic classification of fatty liver in three grades. From June 2018 to April 2019, 1047 patients (818 males and 229 females) diagnosed as fatty liver among 3607 patients who underwent abdominal ultrasonography at Busan screening center. Ultrasonography was classified into three grades: Grade I (mild fatty liver), Grade II (moderate fatty liver), and Grade III (severe fatty liver) according to the degree of parenchyma texture, acoustic attenuation, Obesity index, hematological test, and metabolic syndrome. The average age of men in each sex increased with the increase of the fatty liver. Body mass index (BMI) and waist circumference were significantly increased in both men and women (p=.000). hematological analysis showed that AST, ALT, ${\gamma}-GTP$, TG, fasting blood sugar, and glycated hemoglobin were significantly different from each other (p<.05). In women, ALT, ${\gamma}-GTP$ and TG showed a significant difference with increasing fatty liver (p<.05). The prevalence of metabolic syndrome was significantly increased in both sexes as the grade of fatty liver increased (p=.000). Based on the results of this study, it is suggested that the use of ultrasound - guided fatty liver according to severity may be useful for the treatment and follow - up of fatty liver if the liver grade is divided in consideration of hematological variables and metabolic syndrome.

Purpose: The proper diagnosis of Meckel's diverticulum (MD) is difficult and delayed because of the variety of clinical manifestations. We reviewed clinical characteristics of symptomatic MD to facilitate early detection. Methods: We analyzed retrospectively the clinical manifestations, diagnostic tools, histopathological findings, and operative findings in 58 patients with symptomatic MD. Results: The male to female ratio was 2.8 : 1. The most common symptom of MD was bleeding. Others symptoms included: vomiting, abdominal pain, irritability, abdominal distension and fever in the order of frequency. The clinical manifestations of symptomatic MD were lower gastrointestinal bleeding, intestinal obstruction, perforation, diverticulitis and hemoperitoneum, in the order of frequency. The causes of intestinal obstruction were intussusception, internal hernia, band, volvulus, invagination, in the order of frequency. Seventy five percent of patient with MD were diagnosed prior to 5 years of age. The most frequently used diagnostic tool was the Meckel's scan. The diverticulum was located 2 cm to 120 cm proximal to the ileocecal valve. The length of the diverticulum ranged from 1 cm to 10 cm and 94% were less than 5 cm. The most common ectopic tissue found in the MD was gastric mucosa. Ileal resection was more frequently performed than diverticulectomy. Conclusion: In cases of unexplained gastrointestinal bleeding, obstruction and repeated intussusception, the meckel's scan, ultrasound and computed tomography shoud be considered to rule out MD, and if clinically necessary, an exploratory laparotomy when needed.

Purpose: Regurgitation, vomiting and feeding intolerance are frequent in the neonates. Esophageal function and gastric peristalsis are not fully developed in the neonates, so we should give attention to reduce the incidence of regurgitation and vomiting after feeding. It is necessary to shorten the gastric emptying by change of feeding types and postprandial postures. Gastric emptying time was measured by ultrasound in the neonates to evaluate the effect of feeding types and postprandial postures. Method: We measured gastric antral cross sectional area along the abdominal aorta at the level of the superior mesenteric artery in longitudinal section at NPO state (4 hours after feeding), 0 and every 30 min. after feeding until the value goes below or back to the NPO state. Fifteen neonates were examined in each breast-fed and formula-fed group in supine position. Eighteen and 15 neonates were examined in supine and prone posture after formula feeding, respectively. We used 5 MHz convex prove with Aloka Echo Camera SSD-650. Result: 1) Gastric emptying time of breast-fed infants was $76.0{\pm}20.02$ min. which was significantly shorter than $96.0{\pm}20.28$ min. of formula-fed infants. 2) Gastric emptying time on postprandial prone posture was $85.0{\pm}22.43$ min. which was not significantly different from $96.0{\pm}20.28$ min. on postprandial supine posture. Conclusion: Breast feeding is strongly recommended to the neonates to shorten gastric emptying time. So we can expect to reduce the incidence of regurgitation, vomiting and feeding intolerance. The postprandial posture depends on the traditional trend which is safe and comfortable to the mothers.

Background: Egypt has the highest prevalence of HCV infection in the world (~14.7%). Around 10-15% of HCV-infected persons will advance to cirrhosis within the first 20 years. The incidence of HCC is expected to grow in the next two decades, largely due to HCV related cirrhosis, and detection of HCC at an early stage is critical for a favorable clinical outcome. No simple reliable non-invasive marker has been available till now. B2M, a non-glycosylated polypeptide composed of 99 amino acids, is one of the components of HLA class I molecules on the surfaces of all nucleated cells. It has been reported that the level of serum B2M is elevated in patients with chronic hepatitis C and HCV-related HCC when compared to HCV-negative patients or healthy donors. Determining the clinical utility of serum B2M as a marker for disease progression in Egyptian patients with HCV related chronic hepatitis, cirrhosis and hepatocellular carcinoma was the aim of the present study. Materials and Methods: In this analytical cross sectional study 92 participants were included in 4 equal groups: Group (1) non cirrhotic chronic HCV; Group (2) HCV related liver cirrhosis; Group (3) HCC on top of HCV,; and Group (4) healthy controls. History taking, clinical examination, routine labs and abdominal ultrasound were conducted for all patients, PCR and Metavir scores for group (1) patients, and triphasic CT abdomen and AFP for Group (3) patients. B2M levels were measured in serum with a fully-automated IMX system. Results: The mean serum B2M level of Group (1) was $4.25{\pm}1.48{\mu}g/ml$., Group (2) was $7.48{\pm}3.04$, Group (3) was $6.62{\pm}2.49$ and Group (4) was $1.62{\pm}0.63$. Serum B2M levels were significantly higher in diseased than control group (p<0.01) being significantly higher in cirrhosis ($7.48{\pm}3.04$) and HCC groups ($6.62{\pm}2.49$) than the HCV group ($4.25{\pm}1.48$) (p<0.01). There was a significant correlation between B2M Level and ALK, total and direct bilirubin and INR (p<0.05), and a significant inverse correlation between B2M level and albumin, total proteins, HB andWBCS values (p<0.05). There was no significant correlation between B2M level and viral load or Metavir score, largest tumour size or AFP (p>0.05). The best B2M cut-off for HCV diagnosis was 2.6 with a sensitivity of 100%, a specificity of 92%, a positive predictive value (PPV) of 97% and a negative predictive value (NPV) of 100%. The best B2M cut-off for HCC diagnosis was 4.55 which yielded sensitivity, specificity, positive predictive value, negative predictive values of 74%, 62%, 39.5, 87.8% respectively (p-value <0.01) while best cut-off for cirrhosis was 4.9, with sensitivity 74 % and specificity 74%.The sensitivity for HCC diagnosis increased upon B2M and AFP combined estimation to 91%, specificity to 79%, NPV to 95% and accuracy to 83%. Conclusions: Serum B2M level is elevated in HCV related chronic liver diseases and may be used as a marker for HCV disease progression towards cirrhosis and carcinoma.

This retrospective study was performed to describe and evaluate ultrasonographic characteristics of splenic disorders and to pursue any relationship with cytologic or histopathologic diagnoses. Medical records were reviewed for patients that had undergone both abdominal ultrasonographic procedures and ultrasound-guided fine-needle aspiration (FNA) or surgical biopsy of splenic lesions or necropsy from January 2002 to July 2011 at Seoul National University Hospital for Animals. Total 124 dogs, 76 cases with FNA and 48 cases with biopsy, were available for this investigation. The age of dogs ranged from 2 to 17 years ($mean{\pm}SD$ = $9.54{\pm}3.34$ years), with the gender distribution of 61 females (26 spayed) and 63 males (40 neutered). In breed distribution, 114 were purebred dogs and 10 were mixed breed dogs. The dogs represented 26 breeds, with 113 dogs categorized into small-sized breeds. The ultrasonographic appearances of splenic disorders could be classified into 10 types including normal appearance, depending on the distribution and echogenicity of splenic lesions as well as the increase in spleen size and diffuse parenchymal changes. Among 124 cases, 44 (35.4%) had hypoechoic nodules/masses with the highest frequency, followed by 23 (18.5%) with multiple small hypoechoic nodules. Of 124 cases, 70 (56.5%) were benign and 54 (43.5%) were malignant lesions at cytologic or histopathologic results. Each ultrasonographic appearance had variable cytologic or histopathologic diagnoses. However, diffuse heterogenicity and diffuse hypoechogenicity were significantly associated with malignancy (p < 0.05), whereas hyperechoic nodules/masses were more often associated with benignity (p < 0.05). Based on our results, it may be considered that the ultrasonographic examination for spleen could be able to provide the least information necessary for benign and malignant lesions in prioritizing differential diagnoses.
