Objectives : This study was conducted to find out the effect of Yukmijiwhangtanggamibang (YM) on growth, learning and memory of rats. Methods : It was divided SD rats into Sham group, 192 Saporin injection(SA+Saline) group and Injection of 192 Saporin with YM(SA+YM) group. Growth measure length of bone and tail. Memory performance was used aquisition test and learning retention of morris water maze. It was detected acetylcholinesterase(AChE), cholineacetyltransferase(ChAT) at medial septum and hippocampus by immunohistochemistry Results : Body Weight of the SA+YM Group increased effectively, as compared with SA Saline group. Growth of bone in the SA+YM Group increased effectively, as compared with SA+Saline group. Growth of Tail in the SA+YM Group increased effectively, as compared with SA_Saline group. The SA+YM Group in Aquisition Test improved effectively, as compared with SA+Saline group. The SA+YM Group in Learning Test improved effectively, as compared with SA+Saline group. The numbers of ChAT cells in Medial septum increased effectively, as compared with SA+Saline group. The numbers of ChAT cells in CA1 of Hippocampus increased, but was not effective. Conclusion : These results suggest that YM has an improving effect on the impaired learning through the effects on memory registration and retrieval.

The primary procedural components of deviated nose correction are as follows: osteotomy to correct bony deviation, septal deviation correction, manipulation of the dorsal septum to correct upper lateral cartilage deviation, and correction of functional problems (manipulation for correction of internal valve collapse and hypertrophy of the inferior turbinate). The correction of tip and nostril asymmetry cannot be overemphasized, because if tip and nostril asymmetry is not corrected, patients are unlikely to provide favorable evaluations from an aesthetic standpoint. Tip asymmetry, deviated columella, and resulting nostril asymmetry are primarily caused by lower lateral cartilage problems, which include deviation of the medial crura, discrepancy in the height of the medial crura, and asymmetry or deformity of the lateral crura. However, caudal and dorsal septal deviation, which is a more important etiology, should also be corrected. A columellar strut graft, correction of any discrepancy in the height of the medial crura, or lateral crural correction is needed to correct lower lateral cartilage deformation depending on the type. In order to correct caudal septal deviation, caudal septal shortening, repositioning, or the cut-and-suture technique are used. Surgery to correct dorsal septal deviation is performed by combining a scoring and splinting graft, a spreader graft, and/or the clocking suture technique. Moreover, when correcting a deviated nose, correction of asymmetry of the alar rim and alar base should not be overlooked to achieve tip and nostril symmetry.

Split cord malformations (SCMs) usually present in childhood, and are rarely reported in adults. And also, a cervicothoracic SCM associated with tethered cord syndrome has very rarely been reported in the literature. We report a case of SCM associated with tethered cord and spina bifida in an adult. This report describes the case of a 34-year-old woman who presented for evaluation of neck pain, back pain, and intermittent paraparesis of several months duration. The MRI and CT showed a SCM at the cervicothoracic level and a fibrous septum at the thoracic level. She underwent surgery for the SCM and tethered cord syndrome, and was followed for 7 years. Patient presented complete recovery in the follow-up. The authors discuss this unusual lesion and describe the anatomical relationship of the level of cord duplication and fibrous septum.

Complete and optimal visualization of the mitral apparatus is a prerequisite for accurate repair or replacement of the mitral valve. A vertical left atriotomy just posterior to the interatrial groove is the most commonly used approach. However,exposure can be difficult under certain circumstances,such as small left atrium or reoperation. Other approaches have been advocated to deal with this difficult situations. We used an extended transseptal approach in 10 patients and good clinical results and excellent educational effects were obtained. The extended transseptal approach combines two semicircular atrial incisions circumscribing the tricuspid and mitral annuli anteriorly and superiorly,allowing exposure of the mitral valve by deflecting the ventricular side using stay sutures. The right atrium is opened anteriorly along the atrioventricular sulcus. The atrial septum is incised vertically through the fossa ovalis. Right atrial and septal incisions are joined at the superior end of the interatrial septum and extended across the dome of the left atrium to the left atrial appendage. The mitral valve was replaced in all 10 patients. Four of 10 patients had other simultaneous valve procedure: one had aortic valve replacement: 2 underwent tricuspid annuloplasty: 1 had aortic valve replacement and tricuspid annuloplasty. There was no hospital death and complication. Among the 5 patients who had atrial fibrillation preoperatively,4 had atrial fibrillation postoperatively,1 converted to sinus rhythm. The five patients who were in normal sinus rhythm preoperatively remained in sinus rhythm after replacement. A review of our results with this approach confirms the efficacy and safty of this method. So we recommanded this approach for routine mitral valve procedure,especially difficult situations,such as a small left atrium or the redo operation.

Seventeen patients of pulmonary atresia with intact ventricular septum were underwent operation during 4.8years period from Jan. 1983 to Aug. 1988 at Seoul National university Hospital. The patients were composed of 8 males and 9 females, aging 1day to 2.5 years [mean 88 days]. We classified pulmonary atresia according to right ventricular morphology; those with tripartite ventricles in 12, those with no trabecular portion to the cavity in 0, and those with inlet portion only in 5. The tripartite approach to right ventricular morphology is helpful in selecting the type of initial palliative procedures. Palliative procedures were as follows; pulmonary valvotomy in 5 with 3 early survivors, mod B-T shunt in 4 with 3 early survivors, and palliative right ventricular outflow tract reconstruction in 4 with 1 early survivor. Effective preliminary palliation of pulmonary atresia are pulmonary valvotomy or palliative right ventricular outflow tract reconstruction in those with tripartite right ventricle, and modified Blalock-Taussig shunt in those with no infundibular portion. The approach to definitive repair is based primarily on the actual size of the tricuspid annulus and the right ventricular cavity. Definitive repair was as follows: definitive right ventricular outflow tract reconstruction in 4 with all survivors and mod. Fontan operation in 2 with one survivors. Right ventricular outflow tract reconstruction can be done as complete repair for patients who had adequate tricuspid annulus and right ventricular cavitary size and mod. Fontan operation for patients who severely hypoplastic tricuspid valve annulus or small right ventricular cavity.

In this study, hydraulic characteristics for upstream migration of fish in a pool-and-weir fishway were analyzed through experiment. The results showed that streaming flow was preferable to plunging flow for upstream migration of fish and it was not good to make an orifice beneath the septum since it generates turbulent jet and eddies. Protrusions on the side wall of fishway were preferable to grooves since they decelerate flow velocity and make upstream migration easy. A vertically movable septum was necessary for a flushing of deposited bed material, and net installing over fishway was also needed for birds not to approach the fishway and eat fish.

A symmetric approach, using external rhinoplasty, is presented to aid the plastic surgeon in obtaining improved aesthetic and functional results in patients with postoperative nasal deformities. The external approach yields a full visualization of the underlying nasal framework and intraoperative evaluation of the deformities to be corrected subsequently. The nasal septal cartilage is unequivocally one of the best graft sources for reconstruction of the dorsum, columella or tip. It has fairly even surface and pliability in carving and shaping the graft. The graft can be obtained during the surgery with less morbidity and prepared easily for need of the shape. The only real disadvantage is the limited amount of cartilage that can be obtained from the septum. The dorsal and caudal rims, one or more cm in width, of the nasal septum should not be disturbed to maintain the nasal frame during harvesting the septal graft. Authors invented novel instruments, J & D knife and Flat (Spatula) suction tip, and have employed the devices for harvesting the septal cartilage. We were unable to gain enough amount of the cartilage by using a swivel knife or cartilage scissors. The septal cartilage can be resected as much as needed with newly invented instruments which facilitate a separation(method) technique.

Purpose: The orbital fat buldging may cause irregular contour of lower eyelid, which is not youthful appearance. The conventional method of fat excision may cause the eyeball to move backward and downward, making enopthalmia is inevitable. The transcutaneous approach to reach the orbital septum can increase the risks of scleral show resulting from scarification at the level of the septum orbicularis junction and damaging the vertical motor branches of the preseptal orbicularis oculi muscle of the lower eyelid. Method: From July 2007 to March 2008, total of 21 patients underwent transconjunctival capsulopapebral fascia fixation procedure. In 8 patients, the herniated fat pad of the lower eyelid was relocated back into the orbit without external skin excision using capsulopalpebral fascia fixation. But in 13 patients, excision of redundant skin of the lower eyelid was performed using pinching technique, not involving orbicularis oculi muslce. In 5 patients, lateral canthotomy was done bilaterally for good visual field. In 6 patients, lateral canthopexy was also combined to correct loosening of lower eyelid. Results: Most of the patients were satisfied after at least 5 months of follow up. No patient showed scleral show. But 2 patients complained of undercorrection slightly, without secondary operation in 1 patient and re - capsulopalpebral fascia fixtation through transconjunctival approach in another patient. Conclusion: Orbital fat repositioning using transconjunctival capsulopalpebral fascia fixation is a good procedure to show youthful appearance without increasing the risk of scleral show and also showed fast recovery compared to the conventional transcutaneous approach.

Cor triatriatum is a rare anomaly in old age. This is a case report of a 66 year-old man who had been preoperatively diagnosed as coronary artery disease and cor triatriatum. The operative findings revealed that the left atrium had an intra-atrial septum with one small opening 10mm in diameter, the upper compartment received both pulmonary veins, and there were no other anomalies like anormalous pulmonary venous connection or atrial septal defect. The patient successfully underwent open heart surgery ; the anomalous septum was resected, the mitral valve was reconstructed using French technique with Carpentier-Edwards ring, and coronary artery bypass grafting was performed.

Ventricular septal defects (VSDs) is an opening in the ventricular septum that allows blood to flow between the ventricles. Most ventricular septal defects are located in the upper ventricular septum and can be identified by auscultation. In this report, 2 dogs with heart murmur were diagnosed as VSD using radiography and echocardiography. In radiographs, bulging sign of the main pulmonary artery or the enlargement of the left ventricle was observed. The color Doppler examination showed the left-to-right shunting of blood via interventricular septal defect.
