The objectives of this study was to investigate the incidence and any correction between hemiplegia with pusher syndrome and neuropsychological symptoms such as hemineglect and anosognosia. Pusher syndrome defines that the patient leans toward the hemiplegic side regardless of the position that patient was placed on and resists any attempt for passive correction of posture that would move his weight toward the midline of the body. The subjects of this study were 69 acute hemiplegia who had been rehabilitated at department of rehabilitation medicine, Asan Medical Center from May 1. 1999 through July 31. 1999. The data were analyzed by researchers who were trained for assessment of anosognosia and hemineglect. 12 subjects were excluded for confusion. The method of statistical analysis used for our study was Fisher's exact test. Results of the study disclosed 21 hemiplegia(38.6%) with pusher syndrome. In conclusion, these hemiplegic patients with pusher syndrome did not have any correlation with hemineglect and anosognosia and also had no preference of stroke side.

Objectives : This study was designed to investigate the effects of Sasim-tang (SST) on proinflammatory cytokine production in a photothrombotic ischemia mouse model. Methods : Photothrombotic ischemia was induced in stereotactically held male Balb/c mice using rose bengal (10 mg/kg) and cold light. The target of photothrombotic ischemic lesion was 1 mm anterior to bregma and 3 mm lateral to midline with 2 mm in diameter, which are decreased by oral administration of SST. Results : SST protected ischemic death of brain cells through inhibition of pro-inflammatory cytokines production and catalytic activation of caspase-3 protease in photothrombotic ischemia mouse model. Conclusions : The results of this study suggest that SST can have protective effects on brain cell damage in a photothrombotic ischemia mouse model.

Retroesophageal aortic arch, in which the aortic arch crosses the midline behind the esophagus to the contralateral side, is a rare form of vascular anomaly. The complete form may cause symptoms by compressing the esophagus or the trachea and need a surgical intervention. We report a rare case of a hypoplastic left heart syndrome variant with the left retroesophageal circumflex aortic arch in which the left aortic arch, retroesophageal circumflex aorta, and the right descending aorta with the aberrant right subclavian artery encircle the esophagus completely, thus causing central bronchial compression. Bilateral pulmonary artery banding and subsequent modified Norwood procedure with extensive mobilization and creation of the neo-aorta were performed. As a result of the successful translocation of the aorta, the airway compression was relieved. The patient underwent the second-stage operation and is doing well currently.

A 28-year-old male patient with a history of cystic fibrosis (CF) was referred to the University of Connecticut School of Dental Medicine for an evaluation of a cystic lesion in the right maxilla using cone-beam computed tomography (CBCT). CF is an autosomal recessive disease characterized by an abnormal production of viscous mucus, affecting the mucociliary clearance. The CBCT scan revealed a large cystic lesion in the right maxilla extending from the right maxillary second molar to the midline in the region of the right central incisor with a significant buccal expansion. Further evaluation revealed complete opacification of the paranasal sinuses with medial bulging of the lateral maxillary sinus walls. The maxillary and sphenoid sinuses also appeared hypoplastic. The peculiar finding seen in this case was the presence of marked sclerosis and an increase in the thickness of the adjacent bony framework. This report aimed to describe the common sinonasal findings associated with CF and its underlying pathophysiology.

Purpose: To close anterior cranial base, various types of pedicle flaps have been developed previously. However, the results of those pedicle flaps were not constant. To solve such problem, the author designed bipedicle temporalis-pericranial (BTP) flap based on various types of existing flaps and this study intends to introduce this flap and present clinical application case. Methods: The pedicle of the proposed temporalis-pericranial flap is temporalis muscle. The point of this BTP flap is that because of both sides of the unilateral temporalis-pericranial flap are connected by midline pericranial tissue connected with dense vascular network communicate one another locally, that BTP flap can be safely elevated. The case is a 14 months old male patient of frontoethmoidal encephalomeningocele. Surgery was done in a way that after elevating BTP flap and removing encephalomeningocele, BTP flap was moved intracranially, and to prevent cerebrospinal fluid leakage, anterior cranial base was closed. Results: During 1 year and 6 month outpatient tracking observation, no particular finding like CSF leakage, meningitis or hydrocephalus was observed. Conclusion: The benchmarked BTP flap, effective in the treatment of frontoethmoidal encephalomeningocele, is one of the methods to close intracranium and extracranium.

Single-minded 1 gene (SIM1) is a homolog of Drosophila SIM1 gene which plays a key role in the midline cell lineage of the central nervous system and is implicated in the regulation of feeding behavior and obesity in the human and mouse. In this study, porcine SIM1 gene was firstly mapped to chromosome 1p13 using radiation hybrid (RH) mapping and two polymorphisms were detected at position 607 (A/G) in SIM1 intron7 and position 780 (C/T) in SIM1 exon8. The last substitution was genotyped in a 364 F2 animal-population and an association analysis of these genotypes was performed with growth, carcass and meat quality traits by the statistical animal model. The results showed the significant influence of the SIM1 genotype on growth (p<0.05): live weight at birth, later period of growth and average daily gain; and effects on carcass composition (p<0.05): weight of head and buck kneed foreleg, backfat depth, loin eye area, carcass leaf fat and ham fat weights; and traits related to intramuscular fat content (p<0.05).

Ultrastructure of the excretory duct of the small ampullate gland in the orb web spider, Nephila clavata L. Koch are studied with light and electron microscopes. The small ampullate glands, located near the midline portion of the abdominal cavity, are connected with the spigots(large spinning tubes) on the middle spinnerets and composed of three parts which are the excretory duct, the storage sac and the convoluted tail. The excretory duct of this gland is enclosed by a thin layer of the outer connective tissues. By the morphology of the apical cuticles and internal textures of the epithelial cells, the duct is subdivided into two regions which are proximal duct region near the sac and distal duct region near the spinnerets. At the distal region of the ducts, the subcuticle which had the function of water removal form the progenetive silk material is well developed, whereas at the proximal region this cuticle disappeared and instead of these, endocuticle is developed. Moreover the epithelium of the distal duct region is composed of columnar epithelial cells, but at the proximal region the epithelium is changed to squamous or cuboidal forms. In the cytoplasm of the epithelial cells, rough endoplasmic reticula, Golgi comlexes and large secretory vesicles related to the production of the cuticular materials are well developed. And between the adjacent epithelial cells, specialized septate junction and desmosomes are formed along the plasma membrane.

The kinematic and complicance characteristics of torsion beam axle is structurally related to the location and section profile of torsion beam and the span from body mounting point to wheel center. This paper presents the effect of section properties in torsion beam on the structural characteristics and roll behavior of suspension. The structural characteristics is on the maximum stress on the welding area of torsion beam and the roll behavior is on roll steer and roll-camber of suspension which are important for controllability and stability in cornering. Four factors are used for the section design of torsion beam, which are thickness , midline length, are inner radius, and sector half angle . Through the structural and quasi-static analysis made for six torsion beam axle models, it can be noticed that roll steer and the structural durability of suspension are closely related to warping constant and shear center in section properties of torsion beam.

Background: The Le Fort I osteotomy is one of the most widely used and useful procedure to correct the dentofacial deformities of the midface. The changes of the maxilla position affect to overlying soft tissue including the nasal structure. Postoperative nasal septum deviation is a rare and unpredicted outcome after the surgery. There are only a few reports reporting the management of this complication. Case Presentation: In our department, three cases of the postoperative nasal septum deviation after the Le Fort I osteotomy had been experienced. Via limited intraoral circumvestibular incision, anterior maxilla, the nasal floor, and the anterior aspect of the septum were exposed. The cartilaginous part of the nasal septum was resected and repositioned to the midline and the anterior nasal spine was recontoured. Alar cinch suture performed again to prevent the sides of nostrils from flaring outwards. After the procedure, nasal septum deviation was corrected and the esthetic outcomes were favorable. Conclusion: Careful extubation, intraoperative management of nasal septum, and meticulous examination of preexisting nasal septum deviation is important to avoid postoperative nasal septum deviation. If it existed after the maxillary osteotomy, septum repositioning technique of the current report can successfully correct the postoperative septal deviation.
