The purpose of this study was to examine the effects of lumbar stabilization exercise using the PNF techniques on the lumbar deep muscles thickness and functional activity in chronic low back pain patient. Group I(n=10): general physical therapy group; Group II(n=10): general lumbar stabilization exercise group; Group III(n=10): lumbar stabilization exercise using PNF techniques(stabilizing reversal, rhythmic stabilization, combination of isotonic) group. Change of pain was measured with visual analog scale(VAS). To observe muscle thickness changes, we measured transverse abdominis(TrA), external oblique(EO), multifidus with real time ultrasound scanning. The functional activity were measured with Oswestry Disability Questionnaire(ODQ) and Roland & Morris Disability Questionnaire(RMDQ). In VAS test, group III had more significantly decreased than before exercise. In muscle thickness test, group III had more significantly increased than before exercise in right/left TrA, EO, multifidus. In ODQ & RMDQ test, group III had more significantly decreased than before exercise. This study show that the PNF techniques is effective in improving the lumbar stability and functional activity in chronic low back pain patients.

Purpose: Pedicled transverse rectus abdominis myocutaneous(TRAM) flap has been a gold standard for breast reconstruction and one of surgical techniques preferred by many surgeons. The authors examined the course of deep epigastric artery focusing on distance from margins of rectus abdominis to pedicle and location of choke vessels to get minimal muscles during pedicled TRAM flap operation. Methods: Eleven rectus abdominis muscle from nine cadavers were used in this study. Rectus abdominis was separated from the cadavers, deep inferior and superior epigastric artery were isolated and then 8 anatomical landmarks in medial and lateral margins of rectus abdominis were designated. Distance to a pedicle meeting first horizontally was measured and vertical location from umbilicus to choke vessel was determined. In addition, 32 rectus abdominis images of 16 women(average age: 37.2 years old) from 64 channel abdomen dynamic computerized tomography were also examined with the same anatomical landmarks with those of cadavers. Results: Average distance from four landmarks on lateral margin of rectus abdominis to pedicle was 1.9 - 3.4cm and 1.8 - 3.8 cm on medial margin. Choke vessel was located between middle and inferior tendinous intersection in all cases and average distance between two tendinous intersection was 6.7 - 7.0 cm on medial margin and 6.2 cm on lateral margin. Location of inferior tendinous intersection was on umbilicus or superior of it in all cases and its average distance from umbilicus was 1.8 - 5.6 cm on medial margin and 2.7 - 6.2 cm on lateral margin. Conclusion: Distance from medial and lateral margins of rectus abdominis muscle to pedicle was the shortest in inferior tendinous intersection and that was averagely 1.8 cm on medial margin and 1.9 cm in average on lateral margin. All choke vessels were located between middle and inferior tendinous intersection.

The aim of this study was to investigate the relationships between bite force, masseter muscle and craniofacial morphology. 141 individuals were included. Bite forces were measured with a bite force transducer(SKT 2004). The facial morphology of the samples was evaluated on the Lateral and PA cephalometric radiographs(Asahi CX-90 SP). Ultrasonographic images were obtained for 36 individuals(Logiq 500). General status of the subjects were also measured for investigating possible relationships. Their relationships were analyzed by means of t-test, Pearson's correlation coefficients and simple regression analysis. In conclusion, bite force of molar was significantly correlated with craniofacial morphology for males and females, but not to masseter muscles. The masseter muscle for males had a significant correlation with craniofacial morphology. The unexpected negative correlations between size of masseter muscle and maxillary width was revealed for males. One possible way to arrive at a plausible explanation for the correlation between masster muscle, bite force and craniofacial morphology of males were the deep layer of masseter muscle had a great influence on males and the superficial layer of masseter muscle had a great influence on females.

The biochemical composition of muscle from three deep-sea animals, Tanaka's eelpout Lycodes tanakae magistrate armhook squid Berryteuthis magister, and ocean sunfish Mola mola caught in the East sea in South Korea was determined. The moisture (81.4-93.8 g/100 g), crude protein (5.0-15.6 g/100 g), crude lipid (0.1-1.5 g/100 g), and ash (1.0-1.1 g/100 g) contents of the two fishes were analyzed. The proximate composition of magistrate armhook squid was: moisture 84.0 g/100 g, crude protein 12.4 g/100 g, crude lipid 0.7 g/100 g, and ash 1.5 g/100 g. There was little difference in the proximate compositions of the three animals. The total amino acid contents of Tanaka's eelpout, magistrate armhook squid, and ocean sunfish were 14.64, 10.75, 3.10-9.95 g/100 g, respectively. High levels of glutamic acid, aspartic acid, lysine, leucine, and arginine were found, while low levels of histidine, glycine, and cysteine were detected in the animals. A survey of the free amino acid contents of the animals revealed large amounts of alanine and glycine. Significant differences were found in the fatty acid composition among the three species. Specially, different saturated fatty acids (17.14-40.49%) such as C16:0, and C18:0, monounsaturated fatty acids (19.19-46.88%) such as C16:1, and C18:1, and polyunsaturated fatty acids (35.41-57.08%) such as EPA, and DHA was identified. Our results suggest that each of these deep sea animals possesses nutritional value and should be considered as a foodstuff.

The wide deep penetrating wound of maxillofacial region should be early closed under emergency general anesthesia for the prevention of complications of bleeding, infection, shock & residual scars. But, if the emergency general anesthesia wound be impossible because of pneumoconiosis, obstructive pulmonary disease & hypovolemic shock, early primary closure should be done under local anesthesia by use of much amount of the anesthetic solution. The maximum dose of dental lidocaine (2% lidocaine with 1 : 100,000 epinephrine) is reported to 7 mg/kg under 500 mg (13.8 ampules) in normal adult. But the maximum permissible dose of dental lidocaine can be changed owing to the general health, rapidity of injection, resorption, distribution & excretion of the drug. The blood level of overdose toxicity is above $4.0{\mu}g/ml$ in central nervous & cardiovascular system. The injection of dental lidocaine 1-4 ampules is attained to the blood level of $1{\mu}g/ml$ in normal healthy adult. The duration of anesthetic action in the dental 2% lidocaine hydrochloride with 1 : 100.000 epinephrine is 45 to 75 minutes and the period to elimination is about 2 to 4 hours. Therefore, authors selected the following anesthetic methods that the first injection of 6 ampules is applied into the deeper periosteal layer for anesthetic action during 1 hour, the second injection into the deeper muscle & fascial layer, the third injection into the superficial muscle and fascial layer, the fourth injection into the proximal skin & subcutaneous tissue and the fifth final injection into the distal skin & subcutaneous tissue. The total 26-28 ampules of dental lidocaine were injected into the wound as the regular time interval during 5-6 hours, but there were no systemic complications, such as, agitation, talkativeness, convulsion and specific change of vital signs and consciousness.

This study is to present objective data for the approaches of therapeutic exercise for the correction of genu varum by making an analysis and a comparison of the hip joints' ROM and isokinetic muscles of the female college students with straight legs with those of a female college student with idiopathic genu varum. Additionally, the state of the adductor muscle's thighs and the deep muscles of the subjects with bowed legs were experimented and the equipment's effect and applicability was reviewed through the process of the movement of newly developed exercise equipment, Balloa(2013, Balloa/Adonia/Korea). As a result, a person with genu varum needs the height increasing method for increasing external rotation ROM of a hip joint and requires the exercise techniques to strengthen external rotator muscles and to inhibit the activity of internal rotator muscles of a hip joint. Balloa increases the external rotation ROM of a hip joint and strengthens gluteal muscles, deep muscles, and adductor muscles, and the equipment's function of muscle strengthening shows that the equipment is an effective corrective exercise for the patients of genu varum.

Purpose: An extensive knowledge of the arterial anatomy of the upper extremity and its variations is indispensable to the hand surgeon. We report a patient with anomalous radial artery, superficial course of two radial arteries, encountered during the excision of volar wrist ganglion. Methods: The patient was a 53-year-old man who had a painful mass on the left volar wrist for 1 year. Under general anesthesia, a curved incision was made around the mass. With the skin flaps retracted, the dome of the cyst was identified. Particular care was taken to identify and protect the radial artery, which was intimately attached to the wall of the ganglion. Two radial arteries completely encircled the ganglion. The pedicle was traced to the volar joint capsule, radiocarpal ligament. The joint was open and the capsular attachments were excised. Results: The patient made an uneventful recovery. There were two arterial pulsations at the volar side of the wrist joint. Compressing this site revealed that the major arterial contributor to blood supply in the hand was the ulnar artery. At angioCT, an anomaly of the radial artery was found with a duplication. The pathway of this aberrant artery was superficial to the original radial artery. It changed its course subcutaneously at the level of the tendon of the brachioradialis muscle, and crossing the wrist lateral to the original radial artery and ending in the deep palmar arch. Conclusion: Authors experienced a case of bifurcating radial artery encountered during the excision of ganglion on the volar of the wrist. Because these duplicated radial arteries make strong contributions to the thumb and index finger as well as to the deep palmar arch, when they are present there may be probably less blood supply to the hand from the ulnar artery. If the radial artery is palpated superficially on the brachioradialis muscle, it is important to remember the kind of anomaly.

Objective: To compare the clinical efficacy of concurrent chemoradiotherapy, neoadjuvant chemotherapy, and intracavity brachytherapy in comprehensive treatment for young patients with stage Ib2 cervical cancer. Methods: One hundred and twelve young patients with stage Ib2 cervical cancer were enrolled retrospectively in our hospital from January 2003 to June 2005. They were categorized into three groups according to preoperative regimens, including the concurrent chemoradiotherapy group (Group 1, n=38), the neoadjuvant chemotherapy (Group 2, n=49), and the intracavity brachytherapy group (Group 3, n=25). Radical hysterectomy was performed following these regimens. Chemotherapy and radiotherapy were given according to pelvic lymph node metastasis, deep cervical stromal invasion, intravascular cancer emboli, histological grading, vaginal stump and positive surgical margin. Results: The cancer disappearance and superficial muscle invasion rates were statistically significantly better in the concurrent chemoradiotherapy group than in the other two groups (P<0.01). No statistically significant difference was noted in the deep muscle invasion rate, surgical time and intraoperative blood loss among three groups, but significantly more postoperative complications occurred in the concurrent chemoradiotherapy group. The 2-year pelvic recurrence was statistically significantly lower in the concurrent chemoradiotherapy group compared to other two groups, while the 5-year survival was higher. Conclusion: Concurrent chemoradiotherapy is efficacious for young patients with stage Ib2 cervical cancer.

Over the past few years, a large number of perforator flaps have been revised by several microsurgeons in the USA, France, Canada and Japan. A perforator flap is a flap of skin or subcutaneous tissue that is based on the dissection of a perforating vessel, which is a perforator. In short, a perforator is a vessel that has its origin in one of the axial vessels of the human body. By reducing any muscle harvesting and trauma to a minimum, perforator flaps aim to minimize donor site morbidity, and by avoiding the transfer of dennervated muscle, the long-term bulk of the free tissue transfer becomes more predictable. There are a finite number of potential perforator flaps in the body, which are based on the named source arteries. The most commonly used perforator flaps are deep inferior epigastric perforator, superior gluteal artery perforator, thoraco dorsal artery perforator, medial sural artery perforator, and anterolateral thigh perforator flap. For a better understanding of perforators as a routine reconstructive procedure in oral and maxillofacial surgery, the definition with nomenclature, classifications with special characteristics, and review points for their individual applications must be learned and memorized by the young doctors in the course regarding the special curriculum periods for the Korean national board of oral and maxillofacial surgery. Perforator flaps have been known to have many advantages, so this review article summarized their applications to the maxillofacial reconstruction in the Korean language.

In the past decade, there has been increasing breast reconstructions after mastectomy, and the abdomen has been the gold standard for donor site. TRAM (transverse rectus abdominis myocutaneous), MSTRAM (muscle sparing transverse rectus abdominis myocutaneous), DIEP (deep inferior epigastric artery perforator), SIEA (superficial inferior epigastric artery) flap has been widely used nowadays. Among them, DIEP free flap spares the whole rectus abdominis muscle and anterior rectus sheath resulting in decreased donor site morbidity. Between March of 2006 and February of 2008, six patients had undergone immediate breast reconstructions using DIEP free flap. The mean age of patients was 48.5 years. All patients had unilateral breast reconstructions. We dissected two perforators which were included in the unilateral pedicle. Thoracodorsal artery and its venae comitantes were chosen as recipient vessels. For venous anastomosis, we used the GEM Microvascular Anastomotic Coupler System (Synovis Micro Companies Alliance, Inc., Birmingham, Ala.) in four cases. All flaps were survived completely except one who showed fatty abdomen in old age. She showed repetitive vascular spasm intraoperatively. None of the patients had abdominal hernia, bulge or weakness. We believe that DIEP free flap provides a reliable method for autologous breast reconstruction if the patients are selected appropriately and performed by a skillful surgeon.
