This study was performed to make fundamental data of ultrasonographic diagnosis for liver and duodenum disease in native Korean cattle. Ultrasonographic appearance of liver, caudal vena cava, portal vein, gall bladdr and duodenum according to the growth were determined from 6 to 13 months by monthly examinations in 9 native Korean cattle. The caudal vena cava was determined at 11th intercostal space by use of ultrasonography. The portal vein and gallbladder were determined at 10th intercostal space by use oof ultrasonography. The liver were determined at 12, 11 and 10 th intercostal space by use of ultrasonography. The liver, caudal vena cava, portal cein, gallbladder and duodenum were examinde in standing position. Ultrasonograms were obtainde with 3.5 or 5.0-MHz convex and 5.0-MHz sector transducer. The diameter of vena cava at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 18.4, 20.6, 22.4, 25.1, 26.9, 27.3, 28.5 and 29.4 mm, respectively. The diameter of portal vein at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 19.5, 20.6, 22.3, 24.5, 26.9, 28.1, 30.7 and 31.5 mm, respectively. The diameter of gall bladder at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 63.2, 72.2, 75.1, 78.6, 80.5, 82.3, 84.4 and 91.1 mm, respectively. Cranial part of duodenum was identified near gall bladder by moving of hyperechoic ingesta. Descending duodenum paralleled with vertebrae is seen in the right upper flank and was adjacent to the abdominal wall, and was enveloped in the hyperechoic greater omentum, differentiating it from the jejunum and ileum. The diameter of cranial duodenum at the 6, 7, 8, 9, 10, 11, 12 and 13 months old age were 23.3, 27.9, 29.9, 32.2, 34.4, 34.5, 35.1 and 36.5 mm, respectively. The diameter of descending duodenum revealed smaller diameter than that of cranial duodenum. Calculi in gallbladder were observed by ultrasonography.

Lymphangiomas or cystic hygromas are quite commonly seen in children. During a 22-year period, from January 1980 to December 2001, 117 patients with lymphangioma were treated and followed in the Department of Pediatric Surgery at Hanyang University Hospital. The male-to-female ratio was 1.9:1(77:40) with a male preponderance. As for the age incidence at time of diagnosis, 10(8.5 %) patients were noted under 1 month of age, 37(31.6%) were between 1 month and 1 year of age, 12(10.3%) between 1 and 2 years of age, so 59(50.4%) were under 2 years of age. Sixty one (52.1%) lymphangioma-cases were located in the neck, including one case at the nape. Axilla was the second in frequency and the rest were scattered at various sites. The intrascrotal lymphangioma is very rare but we have experienced one case of primary intrascrotal lymphangioma. Eighteen (15.4%) cases were located in the intraabdominal area, 10 in the mesentery, 2 in the greater omentum and 6 in the retroperitoneum. The chief complaints of intraabdominal lymphangioma were abdominal pain, intestinal obstruction, inguinal hernia, palpable mass, and/or abdominal distension. Among 77 histologically proven cases, 14 cases were cavernous lymphangiomas and the rest were cystic lymphangiomas. Bleeding in the lymphangioma was noted in 20(17.1%) cases of all. As for the treatment, a complete excision was performed in 77(65.8%) patients and $AgNO_3$ sclerotherapy after incomplete excision was performed in 23(19.7%). Picibanil (OK-432) sclerotherapy was performed in 17(14.5%) patients. Recurrence rate was 7.7 % and mortality occurred in one case who had a large neck lymphangioma extending into the mediastinum.

Teratomas arising from totipotential primitive germ cell are composed of 2 or 3 germ cell layers. We reviewed the records of 166 children who underwent the operation for teratoma from Jan, 1990 through April, 2007. There were 40 boys and 126 girls (average age $6.93{\pm}5.83$ years). Primary sites were ovary (n = 88), sacrococcygeum (n = 24), testis (n = 16), retroperitoneum (n = 16), mediastinum (n = 8), brain (n = 4), thymus (n = 3) and a single tumor involved the adrenal gland, neck, middle ear, oropharynx, stomach, pelvis, omentum, chest wall and scalp. Teratomas were mature in 141 patients, and immature in 25. Six patients who had ovarian immature teratomas grade 2 or 3 with peritoneal gliomatosis underwent adjuvant chemotherapy. During follow up period, 6 mature teratomas recurred at sacrococcygeal area (n = 1) and contralateral ovary (n = 5). Five patients of them underwent reoperation and diagnosed as a mature teratoma, but one who had underwent a left salpingooophrectomy with right ovary cystectomy at initial operation was observed carefully. Teratomas were dominant in female patients and developed at various organs. Complete excision was needed for good prognosis. In case of immature teratoma, complete excision and appropriate chemotherapy according to grading can contribute to favorable results.

Recent researches on adipocytes in human and mice model have reported that the adipocytes are not only the fat depots but having role in maintenance of physiology and metabolism through adipokines released by them in accordance to their anatomical location. Ayurveda scholars too have mentioned different tissues like Vasa (inter muscular fat), Meda (visceral fat) and Majja (bone marrow) which are predominantly rich in adipocytes similar to adipose tissues, with a different sites, functions, compositions and pathological outcomes. The metabolic effect of Meda and Majja Dhatu on other tissues like muscle (Mamsa Dhatu), bone (Asthi Dhatu) and reproductive tissue (Shukra Dhatu) shows their functional interdependence. The detailed description of therapeutic indications of Vasa and Majja under Snehakarma (oleation therapy) illustrates that clinical physiology of these tissues have been elaborated rather than general physiology. This article is an attempt to comprehend the physiological aspect of Vasa, Meda and Majja retrospectively on the basis of their therapeutic indication for the management of variety of disorders, in the form of Sneha through different therapeutic procedures. An effort has been also taken to distinguish Vasa, Meda, Majja based on the functional peculiarities of adipocytes present in different sites of body like omentum, muscle and bone marrow. Critical observation of explanations of Vasa, Meda and Majja in Ayurveda compendia and advanced research in field of adipocytes reflected that Ayurveda scholars had deep insights regarding the various dimensions of adipocytes, most of which are in consistent with the advanced physiology and biomolecular studies of adipocytes.

Background: Fat stranding is a non-specific finding of an increased fat attenuation on computed tomography (CT) images. Fat stranding is used for detecting the underlying lesion in humans. Objectives: To assess the clinical significance of fat stranding on CT images for identifying the underlying cause in dogs and cats. Methods: In this retrospective study, the incidence, location, extent, distribution, and pattern of fat stranding were assessed on CT studies obtained from 134 cases. Results: Fat stranding was found in 38% (51/134) of all cases and in 35% (37/107) of tumors, which was significantly higher in malignant tumors (44%) than benign tumors (12%). Moreover, fat stranding was found in more than two areas in malignant tumors (16/33) and in a single area in benign tumors (4/4). In inflammation, fat stranding was demonstrated in 54% (7/13) in a single area (7/7) as a focal distribution (6/7). In trauma, fat stranding was revealed in 50% (7/14) and most were in multiple areas (6/7). Regardless of the etiologies, fat stranding was always around the underlying lesion and a reticular pattern was the most common presentation. Logistic regression analysis revealed that multiple areas (p = 0.040) of fat stranding and a reticulonodular pattern (p = 0.022) are the significant predictors of malignant tumor. Conclusions: These findings indicated that CT fat stranding can be used as a clue for identifying the underlying lesion and can be useful for narrowing the differential list based on the extent and pattern.

A 10-year-old female Pomeranian weighing 2.25 kg with a history of gradual weight loss and an intraabdominal mass confirmed with ultrasonography at a local hospital was referred to the Veterinary Medical Teaching Hospital, Jeju National University. Physical examination revealed abdominal distention. Blood analysis revealed hypoglycemia (57 mg/dL; reference range, 60-110 mg/dL). On abdominal ultrasonography, a heterogeneously hyperechoic mass measuring 7.51 × 10.6 cm was found at the level of the left kidney. Computed tomographic findings showed a unilateral left kidney mass with a 10-cm diameter and vessel contrast enhancement in the corticomedullary phase. Unilateral nephrectomy and ovariohysterectomy were performed because left ovary enlargement was observed during surgery. The renal mass was adjacent to the aorta and vena cava and attached to a portion of the small intestine, greater omentum, and left ovary. The mass was huge (12.5 × 10 × 7 cm) and was 16.5% of the body weight. Histopathological examination revealed renal cell carcinoma (RCC) and ovarian metastasis. After surgery, clinical signs improved remarkably, and serum glucose level returned to normal. As RCC is resistant to radiation and chemotherapy, the owner decided not to proceed with postoperative adjunctive therapies. To the best of our knowledge, this is the first case report of ovarian metastasis with huge RCC in a dog.

Backgrounds/Aims: The present study looked at the role of radical surgery in gallbladder cancers (GBC) with limited metastatic disease. Methods: The retrospective observational study was conducted to screen the database from 1st January 2010 to 31st December 2019. Patients of GBC found to have low-volume metastatic disease upon surgical exploration were included. Results: Of the 1,040 patients operated for GBC, 234 patients had low-volume metastatic disease (microscopic disease in station 16b1 node or N2 disease isolated port-site metastases, or low burden peritoneal disease with deposits less than 1 cm, in adjacent omentum or adjacent diaphragm or Morrison's pouch or a solitary discontinuous liver metastasis in adjacent liver parenchyma) detected intraoperative. Of these, 62 patients underwent radical surgery for R-0 metastatic disease followed by systemic therapy, while the remaining 172 patients did not undergo radical surgery and were given palliative systemic chemotherapy. Patients who underwent radical surgery had significantly superior overall survival (19 months versus 12 months, p < 0.01) and superior progression-free survival (10 months versus 5 months, p < 0.01) when compared to the rest. This difference in survival was more significant amongst patients when operated on after neoadjuvant chemotherapy. Regression analysis showed that a sub-group of patients with incidental GBC with limited metastases showed more favorable outcomes with radical surgery. Conclusions: Authors suggest a possible role for radical treatment of advanced GBC with a limited metastatic burden. Neoadjuvant chemotherapy can be used for preferentially selecting patients of favorable disease biology for curative treatment.
