In recent years, gonorrhea has been pandemic and remains one of the most common STDs in the world, especially in developing countries. For the detection of a more effective therapeutic regimen and assessing the prevalence of Penicillinase Producing Neisseria gonorrhoeae(PPNG), we have been trying to study the patients who have visited the Venereal Disease Clinic of Choong-Ku Public Health Center in Seoul since 1980 by menas of the chromogenic cephalosporin method. In 1998, 93 strians of N. genorrhoeae were isolated, among which 60(64.5%) were PPNG. The prevalence of PPNG in Seoul, which had been decreased to 39% in 1996 after a peak of 74.3% in 1993, is increased to 64.5% in 1998.

본 연구는 쑥, 인삼 및 쑥과 인삼 병용첨가가 흑염소육 중의 지질, 지방산 조성 및 TBA가에 어떤 영향을 미치는지를 알아보기 위하여 실시하였다. 그 결과 쑥, 인삼 및 쑥과 인삼 병용첨가 사육시 총지질을 유의하게(p<0.01) 저하시키는 작용이 있었으며 흑염소육의 지방산 조성을 크게 변화시켜 linoleic acid 함량을 낮추면서, palmitic acid 함량을 증가시켰다. 또한, 흑염소육의 TBA가를 유의하게(p<0.05) 낮추는 것을 볼 때 흑염소육에 다량 함유된 불포화 지방산의 산패를 억제하는 것으로 사료되었다. 이들 결과는 흑염소육의 노린내를 제거해 육질을 개선시키는 필요한 기초자료가 될 것으로 기대된다. This study was performed to investigate the effects of mugwort and ginseng on the fatty acid composition and TBA value of meats in Korean Native Goat. A Total of 12 Korean Native Goats were equally into four groups; Control, Mugwort(4%), Ginseng(1%), Mugwort & Ginseng(4%+1%) groups were supplemented to the basal diet for 40days. These Korean Native Goats with the liveweight of average 9.9kg were slaughtered to obtain samples from loin. Meat samples stored at -20℃ for 7days were analyzed quantitatively to obtain the changes of fatty acid composition and TBA value in total lipid. The results obtained were summarized as follows : 1. Total lipid contents were significantly(P<0.01) low in Ginseng and Mugwort & Ginseng groups, compared with the Control group. 2. Composition of fatty acid in total lipid of loin were categorized with 6 different fatty acids. Palmitic acid content from loin was highest among saturated fatty acid followed by stearic acid and myristic acid, and oleic acid content was highest among unsaturated fatty acids followed by linoleic acid and palmitoleic acid. Palmitic acid levels decreased remarkably in Mugwort, Ginseng and Mugwort & Ginseng groups, compared with the Control. Linoleic acid levels also decreased in Mugwort, Ginseng and Mugwort & Ginseng groups. The ratio of the compositions of unsaturated and saturated fatty acids in total lipids increased remakably in Mugwort, Gineng and Mugwort & Ginseng groups compared with the Control group. 3. TBARS(thiobabituric acid related substance) of mugwort, ginseng or mugwort & ginseng supplementation to the diet decreased significantly(p<0.05) in loin. These results indicate that mugwort or ginseng supplementation in Korean Native Goat may be effective, to increase the stability of meat or decrease total lipid and unsaturated fatty acids.

The purpose of this study was to interpret the symptoms of competitive state anxiety and it's effects on sports performance. The study was designed to confirm the multidimensionality of competitive state anxiety, examining exactly that the symptom interpretation, intensity dimension of cognitive and somatic anxiety have effects of performance. The subjects of this study were 13 male high school Korean golf players who participating in a first national Se-ri's Cup junior championship and 17 Korean western style archery players participating in a 30th national championship. All subjects completed the revised CSAI-2 which consisted of 45 items to measure intensity and frequency of cognitive and somatic anxiety, 30 mins prior to competition. The collected data was analyzed using multiple regression anlaysis. The conclusions were as follows ; First, the intensity of anxiety alone could not effect sports performance, where as the symptom interpretation of somatic anxiety was represented as an effect on performance. Second, the intensity of somatic anxiety was represented by advancement of more the performance through an interaction with the symptom interpretation of somatic anxiety. Third, the intensity of cognitive anxiety and the symptom interpretation of cognitive anxiety were represented being closely realted with the somatic anxiety.

Objectives : High serum cholesterol is one of the major risk factors of coronary artery disease. We investigated the lipid-towering property and the side effects of sesamin, an unsaturated fatty add extracted from sesame oil, for the primary prevention of coronary artery disease. Methods : The 37 patients (20 mates and 17 females) with hyperlipidemia, ages ranging from 22 years to 70 years old (48±12), who did not have atherosderotic diseases except essential hypertension were given three capsules of sesamin once daily for 6 weeks. The lipid profile of the patients were examined before and after sesamin treatment, and the patients were grouped according to the presence or abscence of hypertension, smoking habit and obesity. Result : Compared with pretreatment, the total cholesterol level of sesamin treated group decreased significantly (254.2±29.6 versus 241.6 34.0 ㎎/dl, p< 0.05). The level of LDL-cholesterol (162.6±24.3 versus 156.6±32.8 ㎎/dl)HDL- cholesterol (47.5±10.0 versus 47.0±8.7 ㎎/dl) and triglyceride (196.5±95.4 versus 179.3±96.7 ㎎/dl) and the ratio of LDL/HDL- cholesterol (3.6±0.9 versus 3.4±0.9) were not significantly different. The effect of cholesterol lowering property of sesamin was predominant in hypertensive, non- smoking and obese group (P< 0.05 vs pretreatment). The laboratory tests including complete blood cell counts, serum transaminases, total protein, albumin, blood urea nitrogen, creatinine and blood glucose did not change significantly. Conclusion : The lipid lowering effect of sesamin was statistically significant on the total cholesterol particularly with obese, non-smoking and hypertensive patients. There was no significant side effect during sesamin administration. Therefore, three capsules of sesamin as a single daily dose were effective in lowering total cholesterol and safe to administer in patients with hyperlipidemia.

Deep vein thrombosis is recognized as a common complication in surgical patients in western countries especially in patients with high risk factors. The purposes of this study were to detect leg DVTs in early postoperative period by non-invasive surveillance and to analyze the risk factors of DVT. One hundred seventy one patients who underwent major operations(67 curative resection of colorectal cancer, 64 total hip replacement, 38 femur operation for fracture, and 2 colon resections for benign colon disease) were included for the prospective surveillance of leg DVT within 2 weeks after the operations. For the surveillance of leg DVT, strain gauge plethysmography(SPG) and Duplex scanning of both legs were completed for all patients except 10 patients. These 10 patients were examined in only one leg. The patients with past history of leg DVT or under prophylactic anticoagulant therapy were excluded from this study. To determine the risk factors related with leg DVT formation, age and sex of the patients, indication of surgery or surgical procedures, duration of operation, position during the operation, duration of postoperative immobilization, and preoperative serum level of antithrombin III (AT- III) were analyzed using Chi-square test. After performing SPG of 342 legs, 38 legs, showed abnormal on venous outflow/venous capacitance discriminant line chart, and 13 legs of 12 patients showed the finding(s) suggesting DVT on duplex scanning. Among the patients with abnormal duplex findings, 7 limbs(53.8%) were symptomatic, but the remaining 6 legs were silent. In 6 (15.8%) patients of 36 femur operations, 3(4.7%) of 64 total hip replacements and 3(4.5%) of 67 curative resections of colorectal cancer developed DVT by duplex scanning in the iliac(5), femoral-popliteal(6), and isolated calf(2) veins. After analyzing the risk factors, we could not find any statistically significant(p<0.05) factor related with leg DVT.

The presence of epicanthal folds in Asian eyelids is one of their unique features, in combination with the lack of supratarsal folds. Western culture has influenced many people to prefer to eliminate the prominent epicanthal fold. A number of surgical techniques have been suggested for their correction. However, difficulty with design, excessive and prominent scarring of medial canthal and nasal area, recurrence, and rigidity of application are potential problems associated with many procedures. This paper describes a epicanthoplasty with three-dimensional Z-plasty. Through epicanthal fold incision, the medial canthal tendon is medially advanced and sutured to the periosteum of nasal bone. After the transposition of the flaps, trimming of the flap is usually required. Three-dimensional Z-plasty creates the attractive eyes. From March, 1995 to March, 1997, the technique was applied to 37 patients with epicanthal fold and was performed with or without double-fold operation. There were 34 females and 3 males with ages ranging from 17 to 30 years. Through 2 years follow-up, this technique has delivered esthetically good results with minimal postoperative scar and could made the reduction of ICD from 40 ± 2.13 mm to 34 ± 1.98 mm. The advantages of epicanthoplasty procedure using three-dimensional Z-plasty(Yoon's method) are as follows; 1) simple in design 2)minimal postoperative scar in the medial canthal area 3) versatile in its application 4) no recurrence 5) no hypertrophic scar 6) preserving ethnic identity.

Jyoti Shrestha Takanche,Sang Won Lee,Yae Jin Kim,Young Hee Lee,Jeong Seok Kim,Ji Eun Kim,Ho Keun Yi,Sin Hee Han 한국약용작물학회 2016 한국약용작물학술대회 발표집 Vol.2016 No.10

Background : Tooth vitality is reflected by the health of dental pulp. Schisandrin C is a natural compound extracted from the fruit of Schisandra chinensis which has anti-inflammatory and anti-oxidant properties. The role of Schisandrin C on human dental pulp cells (HDPCs) has not been studied yet. This study examined the properties of Schisandrin C as an anti-inflammatory and anti-oxidant compound, and whether its characteristics promote mitochondrial biogenesis in HDPCs. Methods and Results : HDPCs were extracted from fresh third molars and cultured. Reactive oxidative stress (ROS) and nitric oxide (NO) formation were analyzed by a Muse cell analyzer. Western blotting and gelatin zymography were used to identify the presence of anti-oxidants, as well as inflammatory and mitochondrial biogenesis. Confocal microscopy was used for the detection of mitochondrial activity. Schisandrin C inhibited lipopolysaccharide (LPS)-stimulated inflammatory molecules; intracellular adhesion molecule-1 (ICAM-1), vascular cell adhesion molecule-1 (VCAM-1), matrix metalloproteinase-2 and -9 (MMP-2/9), NO production, ROS formation and the mitogen-activated protein (MAPK) pathway through minimizing the nuclear factor kappa B (NF-kB) translocation. Schisandrin C increased the expression of superoxide dismutase (SOD) enzymes as well as heme oxygenase-1 (HO-1) and peroxisome proliferator-activated receptor gamma coactivator 1-alpha (PGC-1a) through the phosphorylated-protein kinase B (p-AKT) and nuclear factor erythroid 2-related factor-2 (Nrf-2) pathways. The anti-inflammatory and anti-oxidant properties of Schisandrin C promoted mitochondrial biogenesis. Conclusions : These results suggest that Schisandrin C may be used as an anti-inflammatory compound to reduce oral inflammation such as pulpitis.
