  • HGJT has been used for the treatment of general weakness, digestive organ disease and so on. This study was carried out for the purpose of knowing the inhibitory effect on the Type I hypersensitivity and Inflammatory reactions of Hwanggigunjungtang(HGJT). The reasults were obtained as follows: HGJT(0.1. 0.5. 1, 2mg/g) concentration of dependently inhibited compound48/80 induced anaphylaxis reaction in mice. HGJT(2mg/g) also inhibited permeability of evans blue into peritoneal cavity in mice. HGJT reduced IgE, CRP. WBC and Platelets on egg albumin induced hypersensitivity. But serum NO was grown. According to above results, HGJT may be beneficial in the type I hypersensitivity and Inflammatory reactions by inhibition of histamine release from mast cells.

  • Bochdalek hernia is the most common congenital diaphragmatic hernia and that of the foramen of Bochdalek is rare in right side of the diaphragm. Two cases of right Bochdalek hernia were reported in literatures published in Korea. The first case was associated with hypoplasia of the lung and could not be survived. The second case [four months old male infant] was operated on August 28, 1971. at Ewha University Hospital arid survived. The third case was a three months old male infant who had been born at 8th lunar month in a private clinic. During the period of three months prior to admission this premature infant was suf-fered from mild respiratory distress measured as pneumonia. On December 20. 1972, this infant was admitted at Kyung Hee University Hospital with severe respiratory distress developed abruptly. Chest X-ray examination [barium study] demonstrated right diaphragmatic hernia. Right hemithorax was filled with intestines and right lobe of the liver which were repositioned back into the peritoneal cavity through the foramen of Bochdalek. 3. 0 cm x3.5 cm in size, and the defect was closed with interrupt mattress sutures. There was hypospadia with chordee but no other associated anomalies such as hypoplasia of the lung, malrotation or malfixation of intestines, and cardiovascular anomalies. The Postoperative hospital course was not eventful and the baby was discharged on the 14th postoperative day.

  • Statement of problem. Mechanisms of tissue-implant interaction and the effect of the implant surface on the behavior of cells has not yet been clarified. Purpose. This study was performed to investigate the tissue reaction to the titanium alloy submerged into rat peritoneum in vivo. Materials and methods. Titanium alloys (titanium-13Zirconium-6Niobium) were inserted inside the peritoneal cavity of Sprague Dawley rats. After 3 months, the tissue formed around the inserted titanium alloys were examined with a light-microscope. Tissue reaction around the material was analyzed by confocal microscopy to evaluate their biocompatibility in a living body. Results. In in vivo study, foreign body type multinucleated giant cells were found in the fibrous tissue formed as a reaction to the foreign material (4 in 20 cases), but the inflammatory reaction was very weak. After experiment, the contaminants of biomaterials was removed from living tissue. In confocal microscopy, we observed that the staining of vinculin and actin showed mixed appearance. In a few cases, we found that the staining of vinculin and beta-catenin showed the prominent appearance. Conclusion. We found that titanium-13Zirconium-6Niobium alloy was an excellent biomaterial.

  • Ventriculoperitoneal (VP) shunt is commonly and effectively used to treat hydrocephalus. Intracardiac migration of the shunt catheter is a rare complication. A 68-year-old woman underwent ventriculoperitoneal shunting for hydrocephalus secondary to subarachnoid hemorrhage due to anterior communicating artery aneurysm rupture. Two weeks after the shunt surgery, she had suffered from the abdominal pain. Plain chest x-rays, computed tomography, and echocardiography revealed the distal catheter which was in the right ventricle of the heart. We tried to remove the catheter through the internal jugular vein by fluoroscopic guidance. But, the distal catheter was kinked and knotted; therefore, we failed to withdraw the catheter. After then, we punctured the right femoral vein and pulled down the multi-knotted shunt catheter to the femoral vein using the snare catheter. Finally, we removed the knotted distal catheter via the femoral vein and a new distal catheter was placed into the peritoneal cavity. We report a case in which the distal catheter of the VP shunt migrated into the heart via the internal jugular vein. We emphasize the importance of careful and proper placement of the distal catheter during the tunneling procedure to prevent life-threatening complications.

  • This study developed a novel augmented reality interface for minimally invasive surgery. The augmented reality technique can alleviate the sensory feedback problem inherent to laparoscopic surgery. An augmented reality system merges real laparoscope image and reconstructed 3D patient model based on diagnostic medical image such as CT, MRI data. By using reconstructed 3D patient model, AR interface could express structure of patient body that is invisible outside visual field of laparoscope. Therefore, an augmented reality system improved sight information of limited laparoscope. In our augmented reality system, the laparoscopic view is located at the center of a wide-angle concave screen and reconstructed 3D patient model is displayed outside the laparoscope. By using a joystick, the laparoscopic view and the reconstructed 3D patient model view are changed concurrently. With our augmented reality system, the surgeon can see the peritoneal cavity from a wide angle of view, without having to move the laparoscope. Since the concave screen serves immersive environments, the surgeon can feel as if she is in the patient body. For these reasons, a surgeon can recognize easily depth information about inner parts of patient and position information of surgical instruments without laparoscope motion. It is possible for surgeon to manipulate surgical instruments more exact and fast. Therefore immersive augmented reality interface for minimally invasive surgery will reduce bodily, environmental load of a surgeon and increase efficiency of MIS.

  • A hepatic hemangioma is the most frequent benign liver tumor. Once rupture occurs, the bleeding can barely be controlled by using conservative management or endovascular treatment. We report a case of traumatic hepatic hemangioma rupture. A 60-year-old man was referred to our hospital under cardiopulmonary cerebral resuscitation (CPCR). CPCR was continued for 16 minutes after his admission to the emergency room (ER). Computed tomography (CT) showed fluid accumulation in the peritoneal cavity with active contrast extravasation in the left lateral segment of the liver. Percutaneous transarterial embolization and massive transfusion were carried out. Embolization did not stop the bleeding, we decided on an exploration and then resected the lateral segment of the liver to control the bleeding. The specimen showed a ruptured hemangioma in the liver segment.

  • These experiments were conducted to investigate the effect of Taklee Hwangki Tang(THT) on inflammation. THT extract did not affected on the leakage of evans blue into peritoneal cavity and mouse paw edema induced by histamine, but decreased the cottom pellet granuloma formation. Using proliferation of Balb/c 3T3 fibroblast cell line as an in vitro model of granulation tissue formation, the ability of THT to stumulate cellular proliferation of fibroblast cells was investigated. When the cells were seeded at $1{\times}10^4$ cells/well, balb/c 3T3 cells are reached to the late expponential phase at 3rd day. Under the conditions established above, THT increased the proliferation of Balb/c 3T3 cells at concentration of $10^-,\;10^{-6}\;and\;10^{-5}g/ml$. The treatment of $10^{-6}g/ml$ of THT did not influence onthe NDA syntesis and proteinsynthesis of the cells. The $10\%$ serum from THT treated mice(500mg/kg/day for 4 days) increased the proliferation of Balb/c 3T3 fibroblast markedly, but decreased the DNA synthesis and protein sythesis of the cells. The results suggest that THT may be of practical therapeutic use at the period of the last in. flammation.

  • Polymorphonuclear leukocyte (PMNL) was obtained from peritoneal cavity in rat treated with casein. Effects of divalent cations and drugs on leukotriene $B_4(LTB_4)$ formation from arachidonic acid in the PMNL were determined by HPLC assay. 5-Lipoxygenase, a key enzyme for $LTB_4$ formation from arachidonic acid, exhibited $V_{max}$ at $1\;{\times}\;10^{-5}M$, and $K_m$ at $9.89\;{\times}\;10^{-5}M$ of arachidonic acid. Optimal $Ca^{++}$ concentration for the enzyme activity was $1\;{\times}\;10^{-5}M$ but $Zn^{++}$ did not show any significant effects on the $LTB_4$ formation. Indomethacin and caffeic acid exhibited inhibitory effects on the $LTB_4$ formation at $1\;{\times}\;10^{-5}M$ and $4\;{\times}\;10^{-5}M$, respectively. However, 6-aminohexanoic acid did not show any significant effects on the $LTB_4$ formation.
