The purpose of this study was to examine the difference of condylar and ramal vertical asymmetric indices on paonramic radiographs between temporomandibular disorder patients and normal group and according to classification of temporomandibular disorders. One hundred and twenty temporomandibular disorder patients and thirty normal individuals were selected. After tracing the panoramic radiographs, measurements for asymmetric indices were identified. The means and standard deviations of the measurement of each group were calculated and compared between two groups. Through the comparison of the measurement between two groups, following results were obtained 1. As a result of comparing condylar and ramal vertical asymmetry indices of the temporomandibular disorder patients with that of normal group, there was significant difference in condylar vertical asymmetry index between two groups and no significant difference in ramal vertical asymmetry index between two groups. 2. Condylar and ramal vertical asymmetry indices of temporomandibular joint disorder and muscle disorder patients showed greater value than normal group, but there was no significant difference between temporomandibular joint disorder patients and muscle disorder patients. 3. Among temporomandibular joint disorder patients, muscle disorder patients, and normal group, there was only significant difference in condylar vertical asymmetry index between temporomandibular joint disorder patients and normal group. 4. Among disc displacement, disc dislocation with reduction, and disc dislocation without reduction, there were no significant difference in condylar and ramal vertical asymmetry indices. 5. There were no correlation between aging and condylar and ramal vertical asymmetry indices. The results of the present study showed that condylar vertical asymmetry index of temporomandibular disorder patients showed greater values than normal group, and this difference could be considered as the features of temporomandibular disorders. Thus measuring the condylar vertical asymmetry index on panoramic radiographs is considered as the important factor for diagnosis and treatment of temporomandibular disorders.

Antioxidant activities of ethanol and water extracts from Orostachys japonicus leaf, stem, and root were determined by rancimat method, DPPH radical scavenging effect, chelating effect, and reducing power analysis. The highest total phenolic compound (TPC) as 14.6 mg/g of dry sample and the strongest antioxidant activity in rancimat method (value of AI 1.98), DPPH radical scavenging effect (96% in 4 mg/mL), and reducing power (1.50 in 4 mg/mL) were observed in ethanol extracts from Orostachys japonicus leaf. Heat and pH stabilities on antioxidant activity of Orostachys japonicus leaf extract were studied through TPC and DPPH radical scavenging effect. As a result, the extracts from Orostachys japonicus leaf showed high stability. These results suggest that extracts from Orostachys japonicus leaf can be potentially used as proper natural antioxidant in the food industry.

To find the new use of Korean ginseng and mushroom, crude polysaccharides were prepared from submerged cultures of Hericium erinaceum in the medium supplemented with Korean ginseng extracts. When we fractionated crude polysaccharides (HE-GE-CP-1, 3, and 5) from hot-water extracts of submerged cultures of H. erinaceum with ginseng extracts (1%, 3%, and 5% addition of total medium), the yields of HE-GE-CP-1, 3, and 5 were identified at 5.7, 5.1, and 4.8%, respectively. Among crude polysaccharide fractions, HE-GE-CP-5 was significantly higher (1.89-fold of the saline control) than those of HE-GE-CP-1 (1.64-fold) or HE-GE-CP-3 (1.76-fold) on mitogenic activity of splenocytes. HE-GE-CP-5 also had the more potent bone marrow cell proliferation (1.83-fold) rather than HE-CP or HE-GE-CP-1 or HE-GE-CP-3 (1.59- or 1.44- or 1.69-fold, respectively), and anti-metastatic activity as anti-cancer effect showed the highest prophylactic value (72.4% inhibition of tumor control) in 5% supplementation of ginseng extract. However, the lysosomal phosphatase of macrophage was significantly stimulated after HE-GE-CP-3 treatment (2.03-fold). In addition, the immunostimulating and anti-metastatic crude polysaccharide, HE-GE-CP-5, contained mainly neutral sugars (63.2%) with considerable amounts of uronic acid (19.3%) and a small amount of proteins (8.8%). HE-GE-CP-5 can stimulate immune system to inhibit tumor metastasis, and its anti-tumor metastasis may be associated with macrophages, splenocytes and Peyer's patch cells activation.

To synthesize ${\omega}$-3 and ${\omega}$-6 balanced polyunsaturated fatty acid (PUFA) oil mixture, flaxseed oil and sesame oil were mixed and their anti-oxidative and sensory characteristics analyzed. For the fatty acid composition analysis results, the ${\omega}$-3 and ${\omega}$-6 PUFA ratios of the F20S80 oil mixture (flaxseed oil 20% and sesame oil 80% oil mixture) and F10S90 (flaxseed oil 10% and sesame oil 90% oil mixture) were represented as 1 to 10 and 1 to 5 ratio for ${\omega}$-3 and ${\omega}$-6 PUFA content from 4.4% to 42.1% and 8.9% to 39.7%, respectively. Since these were within 1:4~1:10 for healthy functional ${\omega}$-3 and ${\omega}$-6 balanced PUFA oil mixtures, these oil mixtures were healthy functional oil mixtures. To analyze anti-oxidative effects, acid values were analyzed. Samples were stored at room temperature, 70% relative humidity (RH) and $45^{\circ}C$, and 70% RH for 16 weeks. The acid value between F10S90 and S100 stored at $45^{\circ}C$ and 70% RH for 16 weeks were not statistically significant. The sensory characteristics such as oxidative odor and sesame odor and taste were not statistically significant among F20S80, F10S90, and sesame S100. Sensory characteristics between F10S90 and S100 stored at $45^{\circ}C$ and 70% RH for 16 weeks were not statistically significant. In conclusion, the sensory and oxidative characteristics of F10S90 were similar to those of S100. Therefore, F10S90 oil mixture should be used as a ${\omega}$-3 and ${\omega}$-6 balanced PUFA healthy functional oil mixture with high anti-oxidative effects.

This study investigated the quality characteristics and antioxidant activities of Yukwa added with 'Donganme' sorghum bran powder and its extracts. 'Donganme' variety has the highest antioxidant activity among sorghum varieties in Korea. The added contents of sorghum bran to Yukwa were 1% and 5% bran powder of 'Donganme' (BPD 1% and 5%) as well as 0.1%, 0.5%, and 1% bran powder extracts of 'Donganme' (BED 0.1%, 0.5%, and 1%). The contents of protein, ash, and minerals of BPD 1% and 5% added Yukwa were higher compared to non-added and BED 0.1%, 0.5%, and 1% added Yukwa. The contents of flavonoids of BPD 1% and 5% as well as BED 0.1%, 0.5%, and 1% added Yukwa increased by 1.6~17.1 fold, and DPPH and ABTS radical scavenging activities increased by 1.8~7.4 fold and 2.3~13.6 fold, respectively, compared to non-added Yukwa. Yukwa added with BED 1% showed the highest antioxidant activity among the treatments, followed by BPD 5%, BED 0.5%, BPD 1%, and BED 0.1% added Yukwa. The expansion ratios of BPD 5% and BED 1% added Yukwa remarkably decreased compared to those of non-added and other treatments. The sensory evaluation values corroborated the results of the Yukwa expansion ratio. The acid values of Yukwa under high temperature storage ($60{\pm}1^{\circ}C$) increased rapidly after 20 days in all treatments, and those of BPD 5% and 1% added Yukwa increased slowly compared to non-added Yukwa. ABTS radical scavenging activities of Yukwa showed little change during storage in all treatments. As a results, addition of sorghum bran below BPD 1% and BED 0.5% was suitable for antioxidant activity, quality characteristics and sensory evaluation.
Background : Spontaneous pneumothorax have been managed with a variety of methods. The technique most frequently used is chest tube drainage. Small caliber catheters were first used in the management of pneumothorax complicating the percutaneous needle aspiration lung biopsy, and the try to treat spontaneous pneumothorax also has been reported. However, the value of small caliber catheters in spontaneous pneumothorax has not been fully evaluated. So, we tried to elucidate the efficacy of 8 French catheter in the management of spontaneous pneumothorax. Method : From January, 1990, to April, 1994, 44 patients with spontaneous pneumothorax treated at Chung-Ang university hospital were reviewed. The patients were sub-divide into 8 French catheter insertion group (n=21) and chest tube insertion group (n=23). We compared the presence of underlying lung disease, the extent of the collapse, the duration of indwelling catheter and complication between two groups. Results : 1) The duration of indwelling showed no significant difference between 8 French catheter group and chest tube. But, complication after insertion as subcutaneous emphysema was developed in only chest tube group. (p<0.05) 2) In the primary spontaneous pneumothorax, all case of the pneumothorax of which size was less than 50% showed complete healing with 8 French catheter insertion. Whereas the success rate in patients with large pneumothorax (more than 50%) was tended to be dependent on the age. 3) In the patients with secondary spontaneous pneumothorax who were managed with 8 French catheter, the success rate was trended to be high if the underlying disease of pneumothorax was not COPD and if the patient was young. Conclusion : These results show that 8 French catheter insertion probably was effective in the pneumothorax less than 50%, the primary spontaneous pneumothorax, young age or secondary pneumothorax not associated with COPD.
Background : Portable devices for measuring peak expiratory flow(PEF) are now of proved value in the diagnosis and management of asthma and many lightweight PEF meters have become available. However, it is necessary to determine whether peak expiratory flow rate(PEFR) measurements measured with peak flowmeters is accurate and reproducible for clinical application. The aim of the present study is to define accuracy, agreement, and precision of mini-Wright peak flow meter(MPFM) against standard pneumotachygraph. Methods : The lung function tests by standard pneumotachygraph and PEFR measurement by MPFM were performed in a random order for 2 hours in 22 normal and 17 asthmatic subjects and also were performed for 3 successive days in 22 normals. Results : The PEFR measured with MPFM was significantly related to the PEFR and $FEV_1$ measured with standard pneumotachygraph in normal and asthmatics(for PEFR, r = 0.92 ; p < 0.001 ; for $FEV_1$, r = 0.78 ; p < 0.001). The accuracy of MPFM was within 100(limits of accuracy recommeded by NAEP) in all the subjects or 22 normal, mean difference from standard pneumotachygraph being 16.5L/min(percentage of difference being 2.90%) or 10.6L/min(percentage of difference being 1.75%), respectively. According to the method proposed by Bland and Altman, the 95% limits of the distribution of differences between MPFM and standard pneumotachygraph after correction of PEFR using our regression equation were +38.2 and -71.5L/min in all the subjects or 20.49~+9.49L/min in 22 normal and was similar to the intraindividual agreements for 3 successive days in normal. There was no statistically significant difference of PEFR measured with MPFM and standard pneumotachygraph among three days(p > 0.05) and the coefficient of variation($2.4{\pm}1.2%$) of PEFR measured with MPFM was significantly lower than that($5.2{\pm}3.5%$) with standard pneumotachygraph in normal (p < 0.05). Conclusion : This results suggest that the MPFM was as accurate and reproducible as standard pneumotachygraph for monitoring of PEFR in the asthmatic subjects.
Background: Neural control of airway function is through parasympathetic, sympathetic and non-adrenergic, non-cholinergic mechanisms. The autonomic nervous system controls the airway smooth muscle tone, mucociliary system, permeability and blood flow in the bronchial circulation and release of mediators from the mast cells and other inflammatory cells. The cardiovascular and respiratory autonomic efferent fibers have a common central origin, so altered cardiovascular autonomic reflexes could reflect the altered respiratory autonomic status. Therefore, we performed this study to assess the autonomic abnormality and determine the correlating factors of severity of autonomic neuropathy in patients with chronic obstructive pulmonary disease(COPD) using easily reproducible cardiovascular autonomic reflex function test. Method: The study included 20 patients with COPD and 20 healthy persons obtained on Health Promotion Center in Yeungnam university hospital. All the patients had history and clinical features of COPD as defined by the American Thoracic Society. Any patients with myocardial ischemia, cardiac arrythmia, hypertension, central or peripheral nervous system disease, diabetes mellitus, or any other diseases known to produce autonomic neuropathy, has excluded. The autonomic nervous system function tests included three tests evaluating the parasympathetic system and two tests evaluating the sympathetic system. And also all subjects were subjected to pulmonary function test and arterial blood gas analysis. Results: Autonomic dysfunction was more commonly associated with patients with COPD than healthy person The parasympathetic dysfunction was frequent in patient with COPD, but sympathetic dysfunction seemed preserved. The severity of parasympathetic dysfunction in patients with COPD was correlated with the degree of duration of disease, smoking, reductions in the value of $FEV_1$ and FVC, and arterial hypoxemia but no such correlation existed for age, type of COPD, $FEV_1$/FVC, or $PaCO_s$. Conclusion: There is high frequency of parasympathetic dysfunction associated with COPD and the parasympathetic abnormality in COPD is increased in proportion to severity of airway disease. In COPD, parasympathetic dysfunction probably does not the cause of disease, but it may be an effect of disease progression.
Background : We have studied the $^{67}Ga$ SPECT to determine the activity of pulmonary tuberculosis, especially in patients with minimal extent of the disease on chest radiographs. Because active minimal pulmonary tuberculosis is sometimes difficult to diagnose by means of initial chest X-ray, sputum examination and $^{67}Ga$ planar imaging, we compared $^{67}Ga$ planar imaging with SPECT to evaluate minimal pulmonary tuberculosis activity. Methods : $^{67}Ga$ planar imagings and SPECTs of 69 patients suspected of minimal pulmonary tuberculosis by the initial chest X-ray were performed and compared to each other. Active pulmonary tuberculosis was defined by a positive AFB smear and/or culture in the sputum and changes shown on the serial chest X-ray findings. Results : 1) $^{67}Ga$ planar imaging imagings showed positive uptakes in 24 patients and no uptakes in 13 patients, patients, which confirms active pulmonary tuberculosis. But SPECT imagings showed positive uptakes in 25 patients and no uptakes in 12 patients. 2) Patients confirmed with inactive pulmonary tuberculosis showed no uptake on $^{67}Ga$ planar imaging. Only one of the 32 patients confirmed as having inactive pulmonary tuberculosis showed positive uptake on $^{67}Ga$ SPECT imaging. Conclusions : According to the results of our study, $^{67}Ga$ planar imaging and SPECT are both sensitive in detecting the activity of minimal pulmonary tuberculosis. The difference between the two methods is not statistically significant, and the negative predictive value of the $^{67}Ga$ SPECT is not higher than that of $^{67}Ga$ planar imaging.

This study was performed to investigate the effect of ethanol extract of Chaenomeles sinensis Koehne (CS) on alcohol-induced liver damage in rats. Male Sprague-Dawley rats weighing $135{\pm}10g$ were divided into 6 groups for 4 weeks; normal group (ND), alcohol (35%, 10 mL/kg/day) treated group (ET), CS ethanol extract 200 mg/kg/day treated group (ND-CSL), CS ethanol extract 400 mg/kg/day treated group (ND-CSH), CS ethanol extract 200 mg/kg/day and alcohol treated group (ET-CSL), and CS ethanol extract 400 mg/kg/day and alcohol treated group (ET-CSH). The body weight gain and food efficiency ratio were no differences between ND and ET. There were increases in the activities of serum alanine aminotransferase (ALT), asparate aminotransferase (AST), and alkaline phosphatase (ALP) in ET. On the other hand, the administration of CS decreased ALT, AST and ALP activities in serum. It was also observed that the hepatic activities of superoxide dismutase (SOD), catalase, glutathione peroxidase (GSH-Px) and xanthine oxidase (XO) increased by alcohol treatment were also markedly decreased in the CS administered groups as compared with ET. The activities of hepatic SOD, catalase, GSH-Px and XO were riot significantly different among the normal diet groups. Contents of thiobarbituric acid reactive substances (TBARS) were increased by the administration of alcohol, on the other hand, the administration of CS reduced TBARS value in the liver. In addition, the content of glutathione (GSH) in the liver was decreased by alcohol administration, however, GSH increased after administering CS. In conclusion, the administration of alcohol develops the hyperoxidation of liver lipids through tile increase in enzymes activity related to the lipid peroxiation, however, it was decreased after administring CS. Thus, CS may have a possible protective effect on ethanol-induced hepatotoxicity in rat liver.
