  • A case of retroperitoneal paraganglioma is presented with fine needle aspiration cytologic features. A 57-year-old woman complained of abdominal discomfort and left flank pain for 2 years. The abdominal CT scan revealed an ovoid mass left to the abdominal aorta. Percutaneous fine needle aspiration was performed from the mass. The smear revealed cellular sheets or groups on hemorrhagic background. The tumor cells were ovoid, round to spindle shaped with mild to moderate cellular pleomorphism. The nuclei were round to ovoid and had evenly dispersed chromatin and small nucleoli. The cytoplasm was amphophilic, finely granular and poorly defined. Cells having large or spindle nuclei were quite frequently observed, however, mitosis was not present The cytologic findings suggested paraganglioma, but the frequent spindle cell pattern and the pleomorphism made it difficult to exclude other endocrine tumors and sarcomas. The clinical, histological and ultrastructural findings as well as cytologic findings contributed to confirmatory diagnosis.

  • Objectives : The present study investigated the anti-obese and blood flow improvement activities of aqueous extracts of ginseng berry (GBe) on the mild diabetic obese mice as compared with metformin. Methods : After end of 56 days of continuous oral administrations of GBe 150, 100 and 50 mg/kg, or metformin 250 mg/kg, anti-obese and blood flow improvement effects - the changes of body weights, body and abdominal fat density by in live dual-energy x-ray absorptionmetry (DEXA), tail bleeding time, prothrombin time (PT), activated partial thromboplastin time (aPTT), serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) levels, aorta and serum cyclic guanosine monophosphate (cGMP), nitric oxide (NO) and endothelin (ET)-1 levels, aorta phosphorylated PI3K (pPI3K), phosphorylated Akt (pAkt) and phosphorylated p38 MAPK (pp38 MAPK) levels were systemically analyzed. In addition, aorta vascular dilation and constriction related gene mRNA expressions - PI3K, Akt, eNOS, p38 MAPK and ET-1 were also analyzed by realtime RT-PCR. Results : The obesity and related blood flow impairment, induced by 84 days of continuous HFD supply, were significantly inhibited by 56 days of continuous oral treatment of GBe 150, 100 and 50mg/kg, dose-dependently, and they also dramatically normalized the changes of the aorta vascular dilation and constriction related gene mRNA expressions, also dose-dependently. Especially, GBe 150 mg/kg constantly showed favorable inhibitory activities against type II diabetes related obesity and vascular disorders through PI3K/Akt pathway and p38 MAPK mediated cGMP, NO and ET-1 expression modulatory activities, as comparable to those of metformin 250 mg/kg in HFD mice. Conclusion : By assessing the key parameters for anti-obese and blood flow improvement activities on the HFD-induced mild diabetic obese mice, the present work demonstrated that GBe 150, 100 and 50 mg/kg showed favorable anti-obese and blood flow improvement effects in HFD-induced type II diabetic mice, through PI3K/Akt pathway and p38 MAPK mediated cGMP, NO and ET-1 expression modulatory activities.

  • Background: Aortic diseases tend to involve the entire aorta. Hence, there is the constant possibility of the need for a secondary operation at the remnant aorta. This study analyzed our cases of secondary aortic surgery in order to determine its characteristics and problems. Material and Method: Between April 2003 and June 2007, 12 patients (6 male and 6 female) underwent thoracoabdominal aortic replacement as a secondary aortic operation. Their clinical courses were analyzed. Four of the patients underwent lower thoracobadominal aortic replacement under the normothermic femorofemoral bypass, and the others underwent an entire thoracobdominal aortic replacement under deep hypothermic circulatory arrest. Result: There was no death or paraplegia. As local complications, there were 3 cases of wound infection and 2 cases of an immediate reoperation caused by bleeding and one case of delayed wound. revision for a contaminated perigraft hematoma. As a systemic complication, there was one case of renal insufficiency, which required hemodialysis and one case of respiratory insufficiency that needed prolonged ventilator care. The mean admission period was $30{\pm}21$ days. All the patients were followed up for $626{\pm}542$ days without reoperation or other problems. Conclusion: Using properly selected patients and a careful approach, thoracoabdominal aortic replacement can be performed safely as a secondary aortic surgery.

  • By employing the vinylite-and neoprene latex-corrosion technique, ramification and arrangement of A. renalis were observed in fifty Korean native goats (100 kidneys). The obtained results were as follows: 1. A single renal artery, arising on each side from abdominal aorta, bifurcated into Ramus dorsalis and Ramus ventralis from which 3~6 segmental arteries originated. 2. The dorsal and ventral surfaces of the kidney were divided separately into 3~6 arterial segments by the running of the segmental artery into the parenchyma. Of them four segments were mostly frequent (in 77% of right kidney and 83% of left). 3. In 25 of all the kidneys, either dorsal or ventral surface of a kidney was supplied from interlobar or segmental arteries belong to the opposite Ramus. 4. In 3 goats, A. polaris superior was observed. 5. Generally, distribution of the renal artery of Korean native goat resembled that of the dog.

  • This study was conducted to investigate the effect of mulberry leaves on lipid metabolism in cho lesterol induced hypercholesterolemia rats. The mulberry treatment group showed decreases of serum lipid concentration compared with hyperlipidemic group. Also, Mulberry leaves inhibited the activity of HMG Co A reductase, increased lipase activity. In histopathological examination, abdominal aorta showed no critical lesions with mulberry leaves treatment. These results suggest that hypolipidemic effects of mulberry leaves on rats were the inhibition of cholesterol synthesis and acceleration of cholesterol catabolism in the liver. For human, serum triglyceride contents were more significantly decreased with treatment of mulberry leaves powder.

  • We report a case of fatal aortic tumor embolism presenting as acute paraplegia. A four-year-old girl was referred from a local hospital with sudden paraplegia and a poor medical condition. A neighbor had noticed her fall from a bike, and she could not walk. She had no previous illness. Emergency spine MRI revealed no remarkable findings. During the process of evaluation, her general condition deteriorated progressively. Chest and abdominal CT showed a large mass in the left lung field, and a diagnosis of aortic occlusion was made. An emergency transfemoral embolectomy was attempted. However, the patency of the aorta was not recovered. On pathological examination of tissues taken from the embolectomy, a pleuro-pulmonary blastoma was found. The patient died 22 hours after the onset of her symptoms. We describe a possible mechanism for the tumor embolism. To the best of our knowledge, this is the first case report of aortic occlusion caused by an embolic malignancy, presenting as acute paraplegia.

  • Chyloperitoneum or chylous ascite after trauma is a rare condition. It can develop after direct injuries of lymphatic vessels or cisterna chyli. Though isolated chyle duct injury has sometimes been reported, chyloperitoneum is generally accompanied by various kinds of damage to other intraabdominal organs. There's still no established therapeutic protocol regarding the treatment of chyloperitoneum when it is accompanied by the serious injuries of intraabdominal organs. We describe a 66-year-old male with serious intraabdominal organ injuries after blunt trauma. In our case, chyloperitoneum developed due to the injuries to the mesenteric lymph vessels and compression of cisterna chyli by hematoma around aorta.

  • Mesenteric ischemic symptoms appear only when two of the three major splanchnic arteries from the abdominal aorta are involved. Recently, we encountered a case of chronic mesenteric ischemia in a 50-year-old female patient caused by atherosclerotic obstruction of the celiac trunk and superior mesenteric artery. She was treated with a retrograde bypass graft from the right common iliac artery to the superior mesenteric artery (SMA) in a C-loop configuration. Complete revascularization is recommended for treatment of intestinal ischemia. When the celiac trunk is a not suitable recipient vessel, bypass grafting to the SMA alone appears to be both an effective and durable procedure for treating intestinal ischemia.

  • Major bleeding caused by vascular injuries of the abdominal aorta or its branches after blunt trauma often leads to mortality or major morbidity. We report a case that lumbar artery injury following blunt trauma was spontaneously resolved without any surgical or interventional treatment. Lumbar artery injury after blunt trauma could be treated conservatively without surgical or interventional treatment in a selected case. When an aortic or its branch injury was suspicious, diagnostic angiograms in the setting of interventional treatment may be helpful to decide an appropriate treatment modality.

  • Using computational fluid dynamics with the fluid-structure interaction, structural effects of intra-luminal thrombus were determined in thrombosed axisymmetric abdominal aorta aneurysm (AAA) models under pulsatile flow. Four different models, varying dilatations of the aneurysm and Young's moduli of intra-luminal thrombus, were defmed. Compared with unthrombosed AAA models, both von Mises stress and radial displacements in the aneurysm wall significantly decreased. Stiffer intra-luminal thrombus reduced von Mises stress in the aneUtysm wall. The present study supported that intra-luminal thrombus might reduce wall stress in the aneurysm.
