BACKGROUND: In Korean traditional medicine, human beings are classified into 4 groups accordance with the characteristics of physical constitution, named; Taeum, Taeyang, Soum, and Soyang. Most of Korean traditional doctors believe that the back ground of pathophysiology is differ among each group in many diseases. HLA is the most polymorphic gene and related with human immune response. It has been used for determination of individual identification, genetic diversity and a study of disease association in different ethnic group. It has well known that the most human inflammatory disease which thought to have some autoimmune basis are in some way promoted by genes of the HLA region. The purpose of this study is to observe the distribution of HLA-DR genotypes in 4 types of physical constitution in Korean traditional medicine. METHODS: Three hundred and ten Korean subjects(Soyang : 58cases, Soum :142cases, Taeum : 92cases, Taeyang : 18cases) were enrolled for this study. Genomic DNAs extracted by phenol/chroloform were amplified with allele specific primers and determined by 2% agarose gel electrophoresis with ethidium bromide staining for analysis of HLA-DR polymorphism. RESULTS: The genotype frequency of HLA-DR in a total or 310 Koreans was DR1 ; 7.2%, DR 2; 10.5%, DR 3;1.7%, DR 4; 19.9%, DR 5; 11.9%, DR 6;19.9%, DR 7; 7.0%, DR 8; 10.6%, DR 9; 8.7%, DR10;1.9%. There was no significant diffrence of HLA-DR genotype distribution among four physical constitution groups classified by Korean traditional medicine. CONCLUSION: Our results suggest that the classification of physical constitution in Korean traditional medicine is not related to HLA-DR genotypes.

PURPOSE: The goal of this study was to investigate the long-term efficacy and safety of a mixture of polymethyl methacrylate (PMMA) and cross-linked dextran Lipen-10(R) used for penile augmentation under the physical impact generated during sexual intercourse. MATERIALS AND METHODS: From March 2010 to October 2011, a total of 20 patients with a mean age of 44 years (interquartile range, 20~70 years) who requested penile augmentation participated in this study. Lipen-10(R) filler is a mixture of 75% cross-linked dextran, 15% PMMA, and 10% hypromellose solution. With the patient in the supine position, Lipen-10(R) was injected into the subcutaneous tissue between the dartos fascia and Buck's fascia of the penis using a fanning technique. Penile length and circumference were measured before the procedure and six, 12, and 18 months after the procedure. Values were compared using the Student's t-test and the paired t-test. RESULTS: A total of 15 patients completed this study. The increases in circumference and length observed six months after the procedure were found to have been maintained without change at 12 and 18 months of follow-up. At 12 and 18 months of follow-up, no abnormal findings were observed. Pelvic magnetic resonance imaging conducted at 18 months of follow-up showed no trace of the injected filler having migrated to other sites, and the volume was well maintained. CONCLUSIONS: Lipen-10(R), a mixture of PMMA and cross-linked dextran, showed good durability and tolerability over 18 months of follow-up during which the participants were sexually active.

The effectiveness of several sulfhydryl compounds in the treatment of paraquat intoxication has been previously tested based on their antioxidant ability. However, practical guidelines for their clinical use remain to be determined. As a preliminary pharmacokinetic study on sulfhydryl compounds, we attempted to establish the optimal concentration of N-acetyl-L-cysteine, glutathione, superoxide dismutase, and catalase. We measured the antioxidant effect of these antioxidants in normal pooled plasma and on intracellular reactive oxygen species (ROS) induced by paraquat. N-acetyl-L-cysteine begins to suppress the production of ROS in plasma at concentrations as low as 5 mM, with the suppression being maximal at 40 mM. In the same way, glutathione increased the total antioxidant status in plasma at concentrations of 5-40 mM in a dose-dependent manner. Complete suppression of ROS in plasma induced by exposure to 500 micrometer paraquat for 40 min was observed when using 40 mM N-acetyl-L-cysteine and 5 mM glutathione. These concentrations are comparable with 50 units of catalase, which reduced ROS at concentrations of 5-100 units. Further pharmacokinetic study into the systemic administration of these antioxidants is necessary, using effective concentrations of 5-40 mM for both N-acetyl-L-cysteine and glutathione, and 1-50 units of catalase.

It is often difficult, on the basis of clinical examination and conventional investigations, to evaluate the functional impairment of brain in children with cerebral palsy in which early detection remains a challenge. This study was designed to know the usefulness of single photon emission tomography(SPECT) of the brain with technetium-99 m hexamethylpropyleneamineoxime (99mTc-HMPAO) as a semiquantitative method of determination of right-left asymmetries in tracer uptake and a change in antero-posterior regional cerebral blood flow(rCBF) distribution. We investigated 33 children with cerebral palsy aged from 4 months to 48 months(mean 19.3 months). The results were as follows: right to left ratio and regional index of a transverse view were useful to quantify the decrease of tracer uptake in left hemiplegia, but not in right hemiplegia who were all mild in severity, and in tetra- and diplegia in which cerebral lesions were found bilaterally; cortico-cerebellar ratios of a sagittal view were found useful to detect a decrease of rCBF distribution in tetra- and diplegia ,which was not distinct by means of right to left ratio and regional index on transverse view. The results suggest that semiquantitative analysis of 99mTc-HMPAO Brain SPECT would be a valuable complementary tool for determination of topographical involvement in cerebral palsy.

PURPOSE: A lot of surgical techniques were tried to correct extension lag of distal interphalangeal joint. Spiral oblique retinacular ligament reconstruction is the one of correction techniques. METHODS: From January 2004 to January 2005, a total of 13 extension lag of distal interphalangeal joint corrections were performed using spiral oblique retinacular ligament reconstruction for 11 patients. After dorsal incision exposing from base of distal phalanx to proximal phalanx, the new ligament(half of lateral band or graft tendon) lies distally at the dorsum of the distal phalanx and passes volarly and proximally along the side of the middle phalanx and anterior and obliquely across the front of the proximal interphalangeal joint to the opposite side of the digit at the proximal phalanx. RESULTS: 5 of 6 mallet finger deformities and 7 swan neck deformities were corrected, which were both extension lag of distal interphalangeal joint and hyperextension of proximal interphalangeal joint. CONCLUSION: As a result, spiral oblique retinacular ligament reconstruction is an effective and recommendable method for correction of mallet finger deformity and swan neck deformity.

Fingertip is the end of tactile organ and the part of hand most frequently injured. Fingertip injuries should be evaluated on an individual basis considering patient's overall physical condition, medical history, etiology, time of injury, and anticipated future hand use, and accordingly one of various methods of reconstruction should be selected. Complications after the reconstruction of fingertip injuries have been reported as pain, hypersensitivity, numbness, distal paresthesia, cold intolerance, and atrophy. From January to December 2002, dermofat grafts were performed on 15 patients to correct painful fingertips after injury. The thickness of the soft tissue of fingertip was measured both preoperatively and postoperatively with simple X-ray. To evaluate the improvement of pain, visual analogue scale(VAS) was used through the direct interview with patients. The average of postoperative follow-up period was 10.9 months. The average of increased soft tissue thickness ratio was 88.4%(2.3mm to 3.8mm). The average of preoperative VAS was 7.6, and postoperative VAS was 3. Dermofat graft on fingertip needs a further long-term follow-up study for the absorption ratio of dermofat, however, this procedure is simple and could be done under local anesthesia, and would be a useful alternative procedure to correct painful fingertips with the soft tissue atrophy after injury.

Despite the major advances in the microvascular surgery with success rates of up to 98%, failure and vascular complications still remain even in the experienced hands. Failure of blood to flow across an anastomosis is usually caused by three factors: (1) Technical errors; (2) Undetected damage more proximally or via vasospasm; or (3) A clot or a thrombus. The success of a microvascular surgery depends on the severity of the vascular injury and, proper debridement of an injured vessel, and the failure rate of microvascular anastomosis in cases of trauma is higher as the thrombogenic possibility is increased by the endothelial damage. From January to November in 2003, 460 patients were underwent microvascular surgery(270 replantations and 190 free flap transfers) and re-operations were performed in 15 cases. Cases were reviewed by clinical and operative records. In these cases, causes of post-operative circulation insufficiency were identified as 9 vascular spasms and 6 thromboses at the previous anastomotic site. The average of re-operative success rate was 73%(60% in replantations and 100% in free flaps). In conclusion, through precise postoperative monitoring and assessment, immediate surgical re-exploration could be performed when a vascular complication is suspicious, the success rate of microvascular surgery would be increased more.

BACKGROUND: Nonabsorbable sutures are favorable for repairing flexor tendons. However, absorbable sutures have performed favorably in an animal model. METHODS: Two-strand sutures using the interlocking modified Kessler method with polydioxanone absorbable sutures 4-0 were used to repair completely ruptured flexor tendons in 55 fingers from 41 consecutive patients. The medical records of average 42 follow up weeks were analyzed retrospectively. The data analyzed using the chi-squared test, and Fisher's exact test was used for postoperative complications. The results were compared with those of other studies. RESULTS: Among the index, middle, ring, and little fingers were injured in 9, 17, 16, and 13 fingers, respectively. The injury levels varied from zone 1 to 5. Of the 55 digits in our study, there were 26 (47%) isolated flexor digitorum profundus (FDP) injuries and 29 (53%) combined FDP and with flexor digitorum superficialis injuries. Pulley repair was also conducted. Concomitant injuries of blood vessels and nerves were found in 17 patients (23 fingers); nerve injuries occurred in 5 patients (10 fingers). Two patients had ruptures (3.6%), and one patient had two adhesions (3.6%). Using the original Strickland criteria, all the patients were assessed to be excellent or good. Also, fibrosis and long-term foreign body tissue reactions such as stitch granuloma were less likely occurred in our study. Compared to the Cullen's report that used nonabsorbable sutures, there was no significant difference in the rupture or adhesion rates. CONCLUSIONS: Therefore, this study suggests that appropriate absorbable core sutures can be used safely for flexor tendon repairs.
