Zygomatic arch is a prominent structure among facial bone and this is the major cause of vulnerability from the facial trauma. The fracture of zygomatic arch has been treated by ancillary methods of closed reduction approaching through temporal incision or intraoral incision. But, these methods gas a limitation of reduction force vector and it has a difficulty in maintaining the secure fixation of the reduced unstable fractured bones. All 22 cases of zygomatic fracture were reduced by transcutaneous screw and fixed with external fixation device successfully. There was no post-operative complication, such as non union, malunion, and visible scar. This method also has advantages of less post-operative edema and pain.

Medial orbital wall fracture was described by Converse and Smith in the first time in 1957. These fractures which comprise more than 30% of all the orbital wall fracture are may easily be overlooked in routine orbital radiology. Accordingly, examination with orbital CT is essential for accurate diagnosis and appropriate treatment. These type of fracture are followed frequently by post-oprative complication such as diplopia and enophthalmos because it is very difficult to approach to orbital medial was in these operations. The mechanism of the orbital wall fractures are abruptly increased hydraulic pressure by sudden impact on orbital rim or soft tissue of orbital region. So patients who show the signs of subcutaneous emphysema, edema on the orbital region or diplopia need to get through examination with orbital CT for accurate diagnosis and immediate reconstruction of the fractured orbital wall. Conventional approaches in the operations of the orbital medial wall fractures are that with bicoronal incision, subciliary incision, transconjunctival incision and infra-orbital rim incision. But, approach with bicoronary incision, needs broader dissection and longer time for operation. Operations with transconjunctival incision and that with subciliary incision have difficulty to approach to fractured sites. Operations with other conventional methods may be also followed by scar problem. The authors performed reduction and reconstruction of the fractured orbital medial wall fractures successfully without any complications and difficulties by intra-eyebrow approach with which they made incision of 2 - 2.5 cm on mid-area of eyebrow to expose fractured medial wall with good operative field.

This study was made to identify compliance in self-medication, and factors influencing the self-medication of pulmonary TB patients. Self-medication of pulmonary TB patients is a very important factor for the cure of the patients. In this study, variables were used from three theories of health behavior. These were the Health Belief Model, Health Locus of Control, Theory of Planned Behavior. These were included to examine their effect on self-medication. Data were collected during the period from July 1 to August 20, 1994 using a structured questionnaire. And they were analyzed by mean, standard deviation, ANOVA, Pearson Correlation Coefficient, and Multiple Regression analysis using the SAS program. The result were as follows : 1. The mean on the self-medication scores ranging from 6.0 to 12.0 was 10.93. The mean for the self-evaluation scores of the self-medication ranging from 50.0 to 100.0 was 86.51. 2. There were significant associations between the scores on self-medication and age(F=2.34, p=0.033), and method of treatment(F=4.65, P=0.018). And there were significant associations between the self-evaluation scores of self-medication and age (F=3.79, P=0.000), and presence of TB patients among family(F=4.92, P=0.000). 3. (a) The relationship between the scores on self-medication and perceived barrier in health belief revealed a significant correlation(r=-.2046, p=0.0082). (b) The relationship between the scores on self-medication and other-dependency in LOC revealed a significant correlation(r=0.2322, p=0.0018). (c) The relationship between the self-evaluation score of self-medication and other-dependency in LOC revealed a significant correlation(r=0.1946, p=0.0122). (d) The relationship between the attitude in self-medication of the subjects and the self-evaluation score of self-medication revealed a significant correlation(r=0.2102, p=0.0066). 4. (a) 14.8% of the score of compliance in self-medication of the subjects was explained by five variables : Behavioral Intention, Duration of Treatment, Age, Perceived Sensitivity and Perceived Sensitivity and Perceived Barrier. (b) 8.7% of the score of self-evaluation of self-medication was explained by three variables : Perceived Control, Perceived Sensitivity, and Age. In conclusion : This study provides insights and information which may be valuable for motivation and instruction to improve compliance in self-medication among pulmonary TB patients.

It has been shown that wornen with endometriosis have several immunological defects. The effect of interleukin-2 (IL-2) for the treatment of induced endometriosis in rat was studied. The results obtained are as followings: proliferation of epithelium is increased, and the inner surface is undulated with 1.5 nM IL-2. In 7.5 nM IL-2, the epithelial cells are changed to columar ones, and secretory hobs are observed at the apex of individual cell. Secretory activity of epithelium is increased with 0.5 nM IL-2, and apoptosis of the epithelial cell is observed in 15 nM IL-2. The levels of progesterone and estradiol in sera of rat were increased after treatment with IL-2 and were highest in the concentration of 1.5 nM IL-2. The results of this study can be a guide in the development of new therapeutic approaches for the treatment of endometriosis.

PURPOSE: The purpose of this study is to prove that orthognatic surgery on asymmetric prognathism patients improve the temporomandibular dysfunction. MATERIALS AND METHODS: All 30 patients underwent mandibular setback with B-SSRO including 22 patients Le Fort I surgery in KyungHee medical center. Preoperative and postoperative PA cephalograms & transcranial radiographs were measured midline deviation in Mx and Mn, occlusal canting change, condyle position, the temporomandibular dysfunction were checked before surgery, within 1 month after surgery, 3~6 months, 12-24 months after surgery respectively. RESULTS: The temporomandibular dysfunction were relieved after surgery in 17 patients of 25 patients. CONCLUSION: Orthognatic surgery may benefit the temporomandibular joint dysfunction in facial asymmetry patients by obtaining a postoperative stable occlusion and better physiologic neuromuscular function. Specially impovement of occlusal canting may reduce condyle displacement of midline deviation side and the temporomandibular joint dysfunction.

DNA double-strand breaks (DSBs) occur commonly in the all living and in cycling cells. They constitute one of the most severe form of DNA damage, because they affect both strand of DNA. DSBs result in cell death or a genetic alterations including deletion, loss of heterozygosity, translocation, and chromosome loss. DSBs arise from endogenous sources like metabolic products and reactive oxygen, and also exogenous factors like ionizing radiation. Defective DNA DSBs can lead to toxicity and large scale sequence rearrangement that can cause cancer and promote premature aging. There are two major pathways for their repair: homologous recombination(HR) and non-homologous end-joining(NHEJ). The HR pathway is a known "error-free" repair mechanism, in which a homologous sister chromatid serves as a template. NHEJ, on the other hand, is a "error-prone" pathway, in which the two termini of the broken DNA molecule are used to form compatible ends that are directly ligated. This review aims to provide a fundamental understanding of how HR and NHEJ pathways operate, cause genome instability, and what kind of genes during the pathways are associated with head and neck cancer.
