Background : Excessive intakes of $\omega$6 polyunsaturated fatty acid (PUFA) can increase oxidative stress, which may increase insulin resistance and could be the cause of metabolic syndrome X such as diabetes mellitus. One of the ways to reduce oxidative stress is the consumption of antioxidants such as vitamin E. It is controversial that vitamin E intakes may alleviate insulin resistance. The purpose of the study was whether high vitamin E intake may influence whole body glucose disposal rate(GDR), glycogen deposites, triglyceride content, lipid peroxide levels and antioxidant enzyme activities in Sprague Dawley rats fed high $\omega$6 PUFA diest. Methods : Sprague Dawley rats were divided into three groups. The control group consumed chow diet. High and low vitamin E groups consumed 40% PUFA of total energy intakes. One kilogram of diet mixture contained 300IU of $\alpha$-tocopherol in high vitamin E group, while it had 30 IU in low vitamin E group. Diets were given for 8 weeks. After 7 were of diet consumption, indwelling catheters were inserted in carotid artery and jugular vein of all rats so that GDR could be measured in awake and unstressed state. Results : Daily PUFA intakes were lower in the control group than others. Daily vitamin E intake of high vitamin E group was about ten times higher than those of low vitamin E group and the control group(p<0.0001). $\alpha$-tocopherol content in lier was highest in the high vitamin E group. GDR of the control group was 24% higher than others, and vitamin E intakes did not affect GDR. Glycogen deposit of liver in the control group was significantly higher than others, and it was not altered by vitamin E supplementation. Muscle glycogne content showed a similar tendency as liver glycogen in different diet groups. Triglyceride deposit in muscle was not different among groups. Lipid peroxide content of liver in the high vitamin E group was lower than the low of glutathione peroxidase were lowered in low vitamin E group than others, however, those of superoxide dismutase and catalase were not different. Conclusions : High vitamin E intakes can decrease oxidative stress in rats fed high (())-6 PUFA diet, but they cannot alleviate insulin resistance. Thus, increased oxidative stress through high (())-6 PUFA diet may be minimal for influencing insulin resistance.

Surgical resection of tumors in the maxillofacial region sometimes results in extended defects of soft and hard tissue that frequently causes aesthetic, functional and especially mental damages. It is essential for patients with such facial defects to reduce the scar and maxillofacial asymmetry. To attain esthetic facial appearance after hemimaxillectomy, we devise a new design, so called 'IOIO Incision' (InfraOrbital-IntraOral incision). The new approach is established on infraorbital region to expose maxillofacial skeleton in aspect of face. And the other incision is designed on intraoral region. The IOIO incision provide excellent aesthetic result after hemimaxillectomy, because of reduced minimal facial scar contraction. Maxillofacial surgeons are used to designing Weber-Fergusson incision in resection of maxillofacial tumors, but disadvantages of the incision were large scar and asymmetry of face. To improve theses problem, we attempted IOIO Incision.. For correct osteotomy of posterolateral wall of maxillary sinus, 1. Fenestra formation on zygomatic body for easily access of reciprocating saw to posterolateral wall of maxillary sinus. 2. To achieve better visual field in posterolateral aspect of maxilla, fat tissue is removed from infratemporal fossa. This new, versatile procedure can be used for benign and malignant lesions of the maxillary area. We introduce cases with review of literatures.

Ultrasonic shears is currently in wide use as an energy device for minimal invasive surgery. There is an advantage of minimizing the carbonization behavior of the tissue due to the vibrational energy transfer system of the transducer by applying a piezoelectric ceramic. However, the vibrational energy transfer system has a pitfall in energy consumption. When the movement of the forceps is interrupted by the tissue, the horn which transfers the vibrational energy of the transducer will be affected. A study was performed to recognize different tissues by measuring the impedance of the transducer of the ultrasonic shears in order to find the factor of energy consumption according to the tissue. In the first stage of the study, the voltage and current of the transducer connecting portion were measured, along with the phase changes. Subsequently, in the second stage, the impedance of the transducer was directly measured. In the final stage, using the handpiece, we grasped the tissue and observed the impedance differences appeared in the transducer To verify the proposed tissue distinguishing method, we used the handpiece to apply a force between 5N and 10N to pork while increasing the value of the impedance of the transducer from 400 ${\Omega}$.. It was found that fat and skin tissue, tendon, liver and protein all have different impedance values of 420 ${\Omega}$, 490 ${\Omega}$, 530 ${\Omega}$, and 580 ${\Omega}$, respectively. Thus, the impedance value can be used to distinguish the type of tissues grasped by the forceps. In the future study, this relationship will be used to improve the energy efficiency of ultrasonic shears.

Objective : The authors introduce a minimally invasive muscle sparing transmuscular microdiscectomy (MSTM) to treat herniated lumbar disc disease. Its results are compared with conventional subperiosteal microdiscectomy (CSM) to validate the effectiveness. Methods : Muscle sparing transmuscular microdiscectomy, which involves muscle dissection approach using the natural fat cleavage plane between the multifidus to expose the interlaminar space, was performed in 23 patients to treat a single level unilateral lumbar radiculopathy. The creatine phosphokinase (CPK)-MM serum levels were measured on admission and at 1, 3, and 5 days postoperatively. Postoperative pain was evaluated using a 10-point visual analogue scale (VAS) and recorded on admission and at 1, 3, and 5 days postoperatively. The results were compared to those from the conventional subperiosteal microdiscectomy (43 patients). Results : The CPK-MM levels were significantly lower in the serum of the MSTM group compared to the CSM group on postoperative days three and five (p = 0.03 and p = 0.02, respectively). The clinical scales for back pain using VAS were significantly lower in the MSTM group than in the CSM group on postoperative days three (p = 0.04). The mean VAS scores for leg pain in both groups showed no significant differences during the early postoperative period. Conclusion : Muscle sparing transmuscular microdiscectomy is a minimally invasive surgical option to treat lumbar radiculopathy due to herniated disc. The approach affected minimal injury to posterior lumbar supporting structures with alleviated postoperative back pain.

Purpose: Diplopia and cosmetically unacceptable enophthalmos are the major complications of blow out fracture. Prolapse of orbital tissue into the sinuses, enlarged orbital volume, atrophy of orbital fat and loss of support of orbital walls play a role in the pathogenesis of enophthalmos. To correct post-traumatic enophthalmos, freeing of incarcerated orbital contents combined with reduction of bony orbital volume and reconstruction of suspensory support of globe is necessary. But remained enophthalmos after surgical treatment is difficult to correct completely. In this case, the authors performed implant insertion for affected orbit and endoscopic orbital decompression for unaffected orbit for correction of late enophthalmos. Method: We reviewed a girl patient with right inferomedial orbital wall blow out fracture, right zygoma fracture treated at our hospital for correction of enophthalmos. An 18-year-old female had sustained posttraumatic enopthalmos. Two surgical management was performed for correction blow out fracture at the other hospital. But residual diplopia, enophthalmos, cheek drooping were found. And then she transferred to our hospital. She had severe enophthalmos(5 mm) also had diplopia and extraocular muscle limitation. We performed operation for correction of enophthalmos. After operation, she showed minimal improvement of diplopia and enophthalmos(3 mm). The authors make plan for operation for correction enophthalmos due to cosmetical improvement. Implant insertion was performed for affected orbit. For unaffected orbit, nasoendoscopic medial orbital wall decompression was proceeded. Result: Correction of enophthalmos was found after operation and was maintained for nine years follow-up. Patient expressed satisfaction for the result. Conclusion: To correct persistant enophthalmos, we could have satisfactory result with orbital wall reconstruction on affected eye and decompression on unaffected eye.

The purpose of this study was to evaluate the quality properties of Meju prepared by inoculating two strains of Bacillus amyloliquefaciens HJ5-2, and Aspergillus oryzae PS03. The three soybean varieties that include Daewonkong, Daechan, and Saedanbaek were used in this experiment. The fermentation temperature during the Meju aging varied at 20℃, 30℃, and 40℃, respectively. The physicochemical analysis of the soybeans, showed that the cured protein and fat contents were 34.83~43.49% and 12.91~18.90%, respectively. The pH and total acidity were 6.47~6.93 and 0.11~1.22%, respectively. The change in appearance of the Meju was that the yellow-green mold was well formed on seven days at fermentation temperature of 20℃ and 30℃, but at 40℃, there was minimal mold formation and cracking of the surface. The amino nitrogen content was highest on the Daechan Meju at 621.83 mg% for seven days. The amylase increased as the fermentation period increased in all samples, and the protease increased rapidly until the first day of the fermentation, and then gradually increased thereafter. The total number of bacteria increased or decreased as the fermentation proceeded to 6.66~10.07 log CFU/g. The mold counts increased with increasing fermentation period in the range of 6.38~8.79 log CFU/g.

Purpose: Facial rejuvenating surgery has become a challenge to most plastic surgeons. Patients are demanding fewer complications, a prompt recovery, and more natural results. Current trend of the face lift surgery has been developed into less invasive procedures. Every aging patient in Asia wants to look younger without obvious evidence of surgical correction. Methods: The authors performed the limited dissection face lift with PDS quilting suture on twenty five patients. These five quilting sutures consist of sutures at 1~2 cm posterior to the prominent point of zygoma to the periosteum of the zygomatic arch, at the lateral border of Bichat's fat pad area to the zygomatic arch, at the lateral border of the orbicularis oculi muscle to the deep temporal fascia, at the upper lateral border of the platysma to the periosteum of the mastoid, and at the anterior lower margin of the earlobe to the deep temporal fascia by quilting suture technique to achieve rejuvenation. Results: These procedures could produce a balanced volumetric rejuvenation. This method gave considerable benefit of stable and satisfactory results. It provides reduced operative time, well corrected nasolabial fold and neck wrinkle, and swift recovery with minimal complications. Conclusion: Although it could not replace the classic facelift, this technique can be recommended as an option for patients who do not present with advanced facial aging or not want a more extensive procedure.
