Objectives : The purpose of the present study is to observe the neuroprotective effect of the $NeuBo153^{\circledR}$ on transient focal cerebral ischemia in rats. Methods : $NeuBo153^{\circledR}$ was made by mixing the herbs, mainly the root of Panax ginseng, the root of Rehmannia glutinosa and Poria cocos, the stem bark of Acanthopanax senticosus, the root of Scutellaria baicalensis and Mel, and heating for 96 hours. Transient Focal cerebral ischemia (2 h of ischemia, 22 h of reperfusion) was induced by intraluminal suture method with SD rats. Sensory motor function was tested by rotarod test, prehensile traction test, beam balance test and foot fault test at 24 h after ischemia. The brain slices were stained by 2% 2, 3, 5-triphenyltetrazolium chloride and the infarct volume was measured by graphic analyzer at 24 h after ischemia. Results : $NeuBo153^{\circledR}$ treated group did not show significant differences compared with vehicle treated group in body temperature. Oral administration of $NeuBo153^{\circledR}$ reduced brain infarct volume by 29.7% compared with vehicle treated group. $NeuBo153^{\circledR}$ also showed protective effects on sensory motor functional deficits. Conclusion : $NeuBo153^{\circledR}$ treatment reduced brain damage and improved functional deficits induced by MCAo. It showed neuroprotective effects even when treatment was relayed 2 h after injury. Further research is required to evaluating long term functional recovery am accurate therapeutic range and mechanisms.

Chungpaesagan-tang (CPSGT) is most frequently used to treat ischemic brain injury in tradition Korean medicine. Clinically, cerebral ischemia is likely to be accompanied by preexisting or complicating disease. However, animal models used to examine the effects of herbal medicines on cerebral ischemia have not given this issue sufficient consideration. The present study was undertaken to determine the effects of CPSGT on focal cerebral ischemia in normal and SHR rats subjected to transient middle cerebral artery occlusion (MCAO). Animals were divided into four groups: Normal (Sprague-Dawley) rats subjected to MACO (the NC+MCAO group), normal rats subjected to MCAO and then administered CPSGT (NC + MCAO + CP), SHR rats subjected to MCAO (SHR + MCAO), and SHR rats subjected to MCAO and then administered CPSGT (SHR + MCAO + CP). MCAO was performed using the intraluminal method. CPSGT was administrated orally twice (1 and 4 h) after MCAO. All animals were sacrificed at 24 h postoperatively. Brain tissues were stained with hematoxylin & eosin, to examine the effect of CPSGT on ischemic brain tissues. In addition, changes in TNF-$\alpha$ expression in ischemic areas were examined by immunostaining. CPSGT was found to significantly reduce infarction areas in normal and SHR rats and infarction volumes in SHR rats. Similarly, CPGST markedly increased neuron numbers and sizes in all treated groups, except cell sizes in SHRs. Furthermore, CPSGT reduced TNF-$\alpha$ expression in MCAO administered SHR rats. The findings of the present study suggest that CPSGT effectively ameliorates neuron damage caused by MACO-induced cerebral ischemia, and that it has a significant neuroprotective effect after cerebral ischemia in SHR.

Early gastric cancer (EGC) is defined as a carcinoma confined to the mucosa or submucosa of the stomach, with or without lymph-node metastasis. Synchronous liver metastasis is 5. $12.8\%$ in advanced gastric cancer, but is very low in EGC. A 64-year-old woman was admitted to St. Vincent's Hospital with a complaint of epigastric pain. Gastrofiberscopic examination showed a polypoid mass on the gastric antrum. Abdominal computed tomography demonstrated an intraluminal polypoid mass in the gastric antrum, but no tumor mass in the liver. A laparotomy revealed a solitary liver metastasis, we performed a distal partial gastrectomy with a group-2 lymph-node dissection and resection of metastatic liver tumor. Histologic examination showed a tubular adenoma with a focal carcinomatous change, Which was confined to the gastric mucosa and to the metastatic adenocarcinoma in the liver. We present a case of early gastric mucosal cancer associated with synchronous liver metastasis, along with a review of the literature.

A 38-year-old woman presented with facial edema with neck vein engorgement for about 45 days. Chest roentgenography showed bulging soft tissue opacities in the right superoanterior mediastinum and a lobulated intraluminal mass was noted in the superior vena cava on the venacavogram. The superior vena cava was incised and the tumor located from the junction of the superior vena cava and internal jugular vein to the right atrial inlet was excised. Grossly, the tumor was myxoid or gelatinous in appearance. A combination of microscopic and immunohistochemical features showed myxoid leiomyosarcoma arising from the wall of the superior vena cava.

Objectives : This research was performed to investigate the effects of Jodeungsan pharmacopuncture(PA-J) of focal brain ischemia induced by middle cerebral artery occlusion(MCAO) in rats. Methods : The subjects were divided into 4 groups : control, acupuncture, pharmacopuncture PA-J1(11.43 mg / 250 g / $40{\mu}{\ell}$) and pharmacopuncture PA-J2(2.29 mg / 250 g / $40{\mu}{\ell}$). The focal brain ischemia was induced by intraluminal filament insertion into the middle cerebral artery. After 3 days of MCAO, Jodeungsan pharmacopuncture treatment was performed on the GB20, and the day after being treated with pharmacopuncture, the Morris water maze test was carried out on the assigned group. The series of processes were administered 6 times. Thereafter mGluR5, density of neuronal cell and ChAT were measured. Results : The results were as follows. 1. The distance to target significantly decreased in the 2nd trial of the Acu group on the water maze test for short-term memory. 2. The distance to target significantly decreased in the 4th trial of the PA-J2 group on the water maze test for long-term memory. 3. The intensity of mGluR5 significantly increased in the PA-J1 group compared with the control group. 4. The neuroprotective effect on the hippocampal CA1 significantly increased in the PA-J1 and PA-J2 groups compared with the control group. 5. The density of ChAT in the hippocampal CA1 significantly increased in the PA-J1 and PA-J2 groups compared with the control group. Conclusion : These results suggest that Jodeungsan pharmacopuncture may improve memory and cognitive impairment and also have neuroprotective effects on focal brain ischemia.

In off-pump coronary artery bypass grafting (CABG), multiple proximal anastomosis may increase the risk of cerebral embolism (air, debris) and aortic injury (dissection, pseudoaneurysm). Radial artery (RA) has no intraluminal valve such as saphenous vein. We applied Cabrol technique using aortic root replacement for proximal anastomosis in off-pump CABG. Cabrol technique using RA graft can reduce numbers of proximal anastomosis and reduce number of aortic manipulation in off-pump CABG. We report a Cabrol technique for proximal anastomosis in off-pump CABG with RA graft.

A ten-year-old female mongrel dog was presented to Veterinary Medical Center, Chungbuk National University with the signs of anorexia, weakness, and hemoglobinuria. Patient had been diagnosed as dirofilariasis based on heartworm antigen test and treated with adulticide (melarsomine) at local hospital one day before admission. On laboratory examinations, there were hypochromic and microcytic regenerative anemia, thrombocytopenia, moderate neutrophilia, and increase ALT, AST, and ALP. Radiographic exam showed main pulmonary artery bulging, pulmonary infiltration and hypervascularity, reduced abdominal serosal detail and mild hepatomegaly. Abdominal ultrasonographic exam showed mild peritoneal effusion and large hyperechoic thrombi at trifurcation of the porta hepatica and the splenic vein. In addition, intraluminal low density area and intravascular filling defect were confirmed on contrast enhanced CT scanning at the same anatomic locations. Patient was treated with anticoagulant and thrombolytic therapy. On day 42 after treatment, complete resolution of thrombi was confirmed via ultrasonography and improvement of clinical signs was observed.

Idiopathic bronchiolitis obliterans with organizing pneumonia(BOOP) is a specific clinicopathologic syndrome characterized by a pneumonia-like illness, with excessive proliferation of granulation tissue within bronchioles, alveolar ducts and alveoli. The changes are most numerous in alveolar ducts. The presence of intraluminal tufts of organizing connective tissue in alveolar ducts and more distal airspaces has been termed organizing pneumonia. The radiologic manifestations are distinctive with bilateral, diffuse alveolar opacities predominantly in the subpleural and lower lung zone. Patchy migratory pneumonic foci or solely nodular infiltrates are rarely present in BOOP. BOOP is a diagnosis of importance because of its dramatic response to steroids.

Objectives : The purpose of this study was to evaluate the neuroprotective effect of Pueraria lobata extract on focal cerebral ischemia in mice. Methods : Focal cerebral ischemia was induced by occlusion of the right middle cerebral artery using the intraluminal filament model. ICR male mice underwent 90 minutes of middle cerebral artery occlusion (MCAo) followed by 24 hours of reperfusion. Mice were administered Pueraria lobata extract orally at the dose of 300mg/kg just prior to reperfusion. Rotarod test and balance beam test were practiced to assess sensory-motor function 23 hours after MCAo. In rotarod test, the latency to fall on the accelerating rotarod was recorded for 5 min. In balance beam test, the score was graded according to number of slips and latency to cross. The infarct volume was measured 24 hours after MCAo using 2% 2,3,5-triphenyltetrazolium chloride (TTC) staining. Results : Pueraria lobata extract treated group showed significant reduction in infarct volume by 27.3% compared to control group (p<0.05). In rotatod test, it also showed significant extension of latency time compared to control group ($67.82{\pm}15.08$ vs. $5.62{\pm}1.06$, p<0.001). In contrast to performance in rotarod test, that in balance beam test did not improve with Pueraria lobata extract treatment. Conclusions : We conclude that Pueraria lobata extract has a significant neuroprotective effect and reduces damage of sensory-motor function in MCAo model. These findings suggest that Pueraria lobata could be a potent neuroprotective agent.
