OBJECTIVES: This study aims to analyze the association between the severity of sleep apnea, sleep and mood related scales, and activity during sleep in obstructive sleep apnea syndrome (OSAS) patients. METHODS: One hundred seventy six drug-free male patients confirmed as OSAS (average age=43+/-11 years) were selected through nocturnal polysomnography (NPSG). OSAS was diagnosed with apnea-hypopnea index (AHI) >5, mean AHI was 39.6+/-26.0. Sleep related scales were Stanford Sleepiness Scale (SSS), Epworth Sleepiness Scale (ESS), Pittsburg Sleep Quality Index (PSQI) and Morningness-Eveningness Scale (MES). Mood related scales were Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), State-Trait Anxiety Inventory (STAI) I, II and Profile of Mood States (POMS). NPSG was performed overnight with both wrist actigraphy (WATG). Parameters produced from WATG were total activity score, mean activity score and fragmentation index. We analyzed the correlation between each scale, AHI scored from NPSG and activity score analyzed from WATG. RESULTS: ESS showed significant positive correlation with PSQI, BDI, BAI and STAI I, II, respectively (p<0.01). SSS showed significant positive correlation with PSQI and BAI (p<0.05, p<0.01). BAI showed significant positive correlation with total activity score, mean activity score and fragmentation index (p<0.05, p<0.01, p<0.05). Total activity score showed significant positive correlation with ESS and BAI, respectively (p<0.05). Fragmentation index showed significant positive correlation with ESS, PSQI and BAI (p<0.05, p<0.01, p<0.05). AHI, indicator of sleep apnea is showed no significant correlation with each sleep and mood related scale. CONCLUSION: The degree of daytime sleepiness tends to be associated with night sleep satisfaction, depression and anxiety, and the activity during sleep rather than the severity of sleep apnea.

This author tried to find if the size of the frontal sinus can be used as a diagnostic aid to predict the mandibular growth pattern in growing patients-in lateral cephalogram utilizing the fact the the frontal sinus completes its growth in earlier stage but the mandible continues to grow until later. At this study, the 228 samples were divided into 3 groups as skeletal Class I , II, III malocclusions and three indicies(ANB, APDI, Wits) were measured which hidicate the mandibular body length and the antero-posterior relationship of maxilla and mandible to evaluate their relations with frontal sinus. And results were obtained as followings. 1. The size of frontal sinus is highly related to ANB, APDI, Wits and mandilar body length(p<0.001) 2. the size of the frontal sinus of the Cl III malocclusion group was on the lateral cephalogram larger than Cl I and C1 II group.

BACKGROUND: Since dysthymia begins in late childhood or adolescence and has a chronic course, long-term pharmacotherapy may be required. New generation antidepressant, moclobemide, with more acceptable side effect profiles, is effective in the treatment of dysthymia. The main objective of this study was to determine whether they exhibit comparable efficacy and tolerability in dysthymia to amitriptyline. METHOD AND MATERIALS: The efficacy and tolerability of the moclobemide and amitriptyline, were compared in a eight-week single-centre double-blind study in patients(n=37) with dysthymia using he HAMD-17, the Clinical Global Impression Scale(CGI), the Montgomery-Asberg Depression Rating Scale(MADRS), Efficacy Index-Therapeutic Index(EITE), 4-point Index Side Effect Scale(4-PISES), and Efficacy Index-Side Effect Scale(EISE). RESULTS: A total of 37 patients entered the study, 19 were randomly assigned to the moclobemide group and 18 to be amitriptyline group. Demographic and illness characteristics were similar in both groups. There were no significant difference between two groups at the total 17-HDRS score, the HAMD-17% improvement, the total MADRS score, CGI response, and the EITE. In the comparison of EISE between two groups, the scores of the moclobemide group were relatively lower than the amitriptylinen group in full treatment. And the differences were significant(moclobemide group 1.39+/-0.61 ; amitriptyline group 2.00+/-0.85, p<.001). At the 4-PISE. There was no serious or treatment threatening side effects. And there was no specific difference in side effects between two groups. The moclobemide group reported higher EIR scores than the amitriptyline group at every follow up day, but the differences were not significant. And there was no significant differences in the scores of five HRQOL subcategories which is compared between two groups at every follow up days. CONCLUSIONS: In terms of 17-HDRS and MADRS, moclobemide and amitriptyline are equally effective at least in allevating dysthymic symptoms. But moclobemide tended to be less troubling and better tolerated than amitriptyline. Therefore, moclobemide treatment can be used as a safe, and higher satisfactory treatment strategy for the dysthymia.

The purpose of this study was the long-term clinical and radiological evaluation of conservatively treated condylar fractures in children. This study was therefore undertaken to analyze the long-term effects of treating condylar fractures in children with conservative therapy in order to resolve the controversial question of whether complete remodeling occurs in this age or, if not, whether it is more likely to be associated with certain types of fracture or with other factors. This study was based on a series of 11 consecutive children and adolescents, aged between 3 and 15 years, with fractures of the condylar process who had been treated with conservative therapy at the Department of Oral and Maxillofacial surgery, Inha University Hospital, Inchon, Korea. All patients underwent a clinical investigation with special emphasis on Temporomandibular joint function and facial asymmetry. The patients also underwent a radiologic investigation, focusing on fracture remodeling and symmetry of mandible. It consists of panoramic radiograph, PA and lateral cephalogram and 3-D CT. No patient described impaired temporomandibular joint(TMJ) function or pain on the affected side. 2 of 8 (25%) unilateral and 1 bilateral fractures show slight facial asymmetry. Despite apparently excellent recovery of function, there were marked remodeling changes evident on the CT scan. Such changes are not usually evident on panoramic radiograph. Radiologic investigation showed incomplete remodelling(54.5%) and asymmetry of the mandible (27.3%) in some patients. Conservative treatment of condyle fracture in children results in satisfactory long-term outcome of jaw function despite a relative high frequency of radiologically noted aberrations.

Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disorder that leads to a progressive muscle wasting and paralysis. The pathological phenotypes are featured by severe motor neuron death and glial activation in the lumbar spinal cord. Proposed ALS pathogenic mechanisms include glutamate cytotoxicity, inflammatory pathway, oxidative stress, and protein aggregation. However, the exact mechanisms of ALS pathogenesis are not fully understood yet. Recently, a growing body of evidence provides a novel insight on the importance of glial cells in relation to the motor neuronal damage via the non-cell autonomous pathway. Accordingly, the aim of the current paper is to overview the role of astrocytes and microglia in the pathogenesis of ALS and to better understand the disease mechanism of ALS.

A prognathic mandible and prominent gonial angle are considered to be unattractive in the Orient because it gives the face a square and muscular appearance. Requests for contouring of the mandibular angle are rare in the other race but are much more common in Korea and, through out the Orient. So, we often encounter a patient with a prognathic mandible and squarish or broad face who wishes to have his or her facial size reduced minimally or to acquire a round or slender appearance. But, mandibular angle is located in the deepest part of the operative field and the strong tension of the lateral soft tissue makes retraction difficult. It is extremely difficult to reduce the gonial angle with sagittal split ramus osteotomy by intraoral approach at the same time. We apply the method of gonial angle reduction during SSRO and had satisfactory results. We will present our results and hope to give some useful information for management of mandibular deformity.

OBJECTIVE: In the human body the embryo initially gmws in the fallopian tube which is maintained in an 3-8% O2 concentration environment, and various substances such as growth factors and antioxidants present in tbe tubal fluid assists in maintaining a healthy environment for embryo development. But in IVF programs embryo cultures are conducted in incubators with 21.9% O2 and 5% CO2 condition, and such high oxygen concentrations have been reported to increase the production of oxygen free radicals within the embryo and is detrimental to the growth and development of the embryo. The objective of this study, therefore, is to determine the culture conditions which will decrease oxygen free radical production and thereby minimize the injury to the embryo. METHODS: Six to eight week old ICR strain mice embryos were cultured in 5% or 21.9% O2 conditions and in culture media to which inaement concentrations of superoxide dismutase (SOD) had been and the H2O2 concentration within the embryo, embryo developmental rate, and degree of fragmentation of the embryos was investigated. RESULTS: The control gmup embryos which were cultured in 21.9% O2 condition without addition of SOD showed developmental arrest at the 2-cell stage or fragmentation, while those cultured in 21.9% O2 condition with addition of SOD showed development to the blastocyst stage with deaeased fragmentation. In particular, the blastulation and fragmentation rates were the lowest in the group to which 500 IU/ml of SOD was added, but in the 5% O2 enviranment group many embryos reached the blastocyst stage and with no difference in frapnentation with or without addition of SOD. The HO relative intensity (120.5+/-20.2) within the embryos cultured in 21.9% O2 environment without SOD was significantly higher than that (56.8+/-10.8) of group with SOD (p<0.05). As showing that in the 5% O2 environment group without SOD it was 43.8+/-7.8 and in the group with SOD it was 37.3+/-5.4, the H2O2 concentration within embryos cultured in 5% 02 condition was significantly lower those that of 21,9% 02 environment regardless of SOD addition (p<0.05). CONCLUSION: The optimal oxygen concentration in incubator for mice embryo cultures is that which is similar to the 5% 0 concentration in vivo. When 20% 02 incubators are routinely used, the addition of SOD to the culture media will decrease the H2O2 concentration within the embryos with subsequent improvement in development. The optimal concentration which should be used is thought to be 500 IU/ml. It is suggested that the use of the above method in human IVF-ET programs will lead to improved embryo quality and enhanced pregnancy rates.
