Objectives : Jeon-Jeung(癲證) is one of negative symptoms from schizophrenia in Western medecine, which causes flattening of affect, emotional bluntness, and avolition. Compared with positive symptoms of schizophrenia, there is no established treatments that have been proved to be effective for negative symptoms, and since negative symptoms are chronically processed, they finally lead to devastate the mental health. Since Jeon-Jeung(癲證) is usually in set in adolescent period and tends to become chronic through life time, it is important to start getting treatments in early stage by being distinguished from other diseases, such as anxiety disorder. A patient in this case was affective blunting, general weakness, and delusion when sixteen years old. However, he refused to get Western medicine treatment and wanted oriental medicine treatment. Methods : The patient in this case had been suffered from severe stress from his family since he was young and had kept having irregular and unhealthy eating habits. Therefore, he diagnosed stagnant qi transforming into fire(氣鬱化火), heart blood deficiency(心血虛), and spleen-stomach deficiency cold(脾胃虛寒) and since then he had received several treatments including herbal treatment, acupumcture treatment, supportive therapy, and family therapy. These treatments were successful and reduced the level of symptoms. After discharged from the hospital, he had continued receiving outpatient treatment with his family for 8 months and his progress had been still observed after the discharge. Results : The symptoms of patient had been almost reduced and eliminated after he received 29days of admission treatment and the patient got better and better and now lives a normal life 8 months outpatient treatment. Conclusions : This result suggests that our oriental medical treatments and family treatments was effective on schizophrenia.

Acute renal failure refers to a rapid reduction in renal function that usually occurs in an individual with no known previous renal disease. Development of a complication of acue renal failure in critically ill surgical patients is not unusual, and it causes high morbidity and mortality. Acute renal failure can be divided as Pre-renal (functional), Renal (organic), and Post-renal (obstructive) azotemia according to their etiologies. Early recognition and proper correction of pre-renal conditions are utter most important to prevent an organic damage of kidney. These measures include correction of dehydration, treatment of sepsis, and institution of shock therapy. Prolonged exposure to ischemia or nephrotoxin may lead a kidney to permanent parenchymal damage. A differential diagnosis between functional and organic acute renal failure may not be simple in many clinical settings. Renal functional parameters, such as $FENa^+$ or renal failure index, are may be of help in these situations for the differential diagnosis. Provocative test utilyzing mannitol, loop diuretics and renovascular dilators after restoration of renal circulation will give further benefits for diagnosis or for prevention of functional failure from leading to organic renal failure. Converting enzyme blocker, dopamine, calcium channel blocker, and propranolol are also reported to have some degree of renal protection from bioenergetic renal insults. Once diagnosis of acute tubular necrosis has been made, all measures should be utilized to maintain the patient until renal tubular regeneration occurs. Careful regulation of fluid, electrolyte, and acid-base balance is primary goal. Hyperkalemia over 6.5 mEq/l is a medical emergency and it should be corrected immediately. Various dosing schedules for medicines excreting through kidney have been suggested but none was proved safe and accurate. Therefore blood level of specific medicines better be checked before each dose, especially digoxin and Aminoglycosides. Indication for application of ultrafiltration hemofilter or dialysis may be made by individual base.

As there have been growing concerns about the adverse effects of air pollution on birth outcome, studies for this area has been carried out in different populations and sites. We reviewed the epidemiologic studies that evaluated the effects of air pollution on birth outcome such as low birth weight and preterm births. We identified the air pollution exposure during pregnancy was related with low birth weight and preterm birth, although there are differences among studies for the critical period of vulnerability. The biological mechanisms whereby air pollution might influence health of fetus are not clearly established. The exposure to carbon monoxide(CO) during pregnancy could increase fetal carboxyhemoglobin and result in tissue hypoxia. On the other hand, ambient particles less than $10{\mu}m$ in aerodynamic diameter($PM_{10}$) could lead to inflammation and increase blood viscosity. Controlling for potential confounders and valid assessment of exposure are the methodological issues remained in these epidemiologic studies. In the future, more studies are needed to investigate the effect of air pollution on preterm birth or stillbirths, considering the various exposure period and the biological mechanism.

Lairages serve several functions, such as providing post-mortal inspections and providing a reservoir of animals to ensure the slaughter line runs efficiently. High stress lairage conditions can contribute to the accumulation of transport stress in pigs, causing poor pork quality and still stressed pigs at slaughter. The objective of this study was to investigate meat quality, blood profile and behavior changes according to lairage stocking density in in high temperature. Density treatments were as follows: LD, low density (lower than 0.5 m²/100 kg); ND, normal density (0.5 m²/100 kg to 0.83 m²/100 kg); HD, high density (higher than 0.83 m²/100 kg). Air temperature treatment was as follows: HT, high temperature (higher than 24℃). Pigs stocked with LD showed lower pH, WHC (water holding capacity), and higher DL (drip loss) and CL (cooking loss) than those stocked with HD. Pigs stocked with LD showed lower cortisol level than those stocked with HD. Therefore, Pigs exposed to high stock density (lower than 0.5 m²/100 kg) in high air temperature during pre-slaughter caused acute stress and lead to PSE (pale, soft, exudative) pork incidence. Based on obtained results, stocking of too high (lower than 0.5 m²/100 kg) density is generally not good for meat quality and animal welfare at high temperatures.

Background: Hepatitis C virus (HCV) causes acute and chronic human hepatitis infection and as such is an important global health problem. The virus was discovered in the USA in 1989 and it is now known that three to four million people are infected every year, WHO estimating that 3 percent of the 7 billion people worldwide being chronically infected. Humans are the natural hosts of HCV and this virus can eventually lead to permanent liver damage and carcinoma. HCV is a member of the Flaviviridae family and Hepacivirus genus. The diameter of the virus is about 50-60 nm and the virion contains a single-stranded positive RNA approximately 10,000 nucleotides in length and consisting of one ORF which is encapsulated by an external lipid envelope and icosahedral capsid. HCV is a heterogeneous virus, classified into 6 genotypes and more than 50 subtypes. Because of the genome variability, nucleotide sequences of genotypes differ by approximately 31-34%, and by 20-23% among subtypes. Quasi-species of mixed virus populations provide a survival advantage for the virus to create multiple variant genomes and a high rate of generation of variants to allow rapid selection of mutants for new environmental conditions. Direct contact with infected blood and blood products, sexual relationships and availability of injectable drugs have had remarkable effects on HCV epidemiology. Hundreds of thousands of people die each year from hepatitis and liver cancer caused by HCV virus infection. Approximately 80% of patients with acute hepatitis C progress into a chronic disease state leading to serious hepatic disorders, 10-20% of which develop chronic liver cirrhosis and hepatocellular carcinoma. The incubation period of HCV is 6-8 weeks and the infection is often asymptomatic so it is very hard to detect at early stages, making early treatment very difficult. Therefore, hepatitis C is called a "silent disease". Neutralizing antibodies are produced against several HCV proteins during infection but the virus mutates to escape from antibodies. Some patients with chronic hepatitis C may have some symptoms such as fatigue, muscle aches, nausea and pain. Autoimmune and immunecomplex-mediated diseases have also been reported with chronic HCV infection.

This study was conducted to evaluate the weight reduction effect of yeast hydrolysate-SR101. Thirty female college students participated in a 6 week weight control program. All subjects were randomly assigned to either the placebo group, YH-SR101 (yeast hydrolysate-SR101) group, or eX diet (product of yeast hydrolysate-SR101) group. The mean energy intake of the placebo group was 1445.2${\pm}$364.0 kcal (carbohydrate: 60.1%, protein: 25.6%, fat: 14.3%), while those of the YH-SR101 and the eX diet group were 1505.6${\pm}$296.2 kcal (carbohydrate: 60.5%, protein: 22.2%, fat: 14.8%) and 1353.8${\pm}$326.3 kcal (carbohydrate: 63.2%, protein: 20.9%, fat: 15.9%), respectively. The placebo group lost 0.19${\pm}$1.14 kg of body weight, while the treatment groups (YH-SR101 and eX diet) lost 1.13${\pm}$0.83 and 1.54${\pm}$0.74 kg of body weight, respectively. There were significant differences in the decrease in body weight between the placebo and the treatment group (p<0.05). There were also significant differences in the decrease in fat mass between the placebo and treatment group (p<0.05). Furthermore, the BMI of the YH-SR101 and the eX diet groups also differed significantly before and after the diet program (p<0.05). Additionally, the BMI and waist size reduction of the treatment groups (YH-SR101 and eX diet group) differed significantly when compared to the placebo (p<0.05). The reduction of the resting metabolic rate (RMR) blood glucose, total-cholesterol, HDL-cholesterol, LDL-cholesterol and triglyceride did not differ significantly among groups. Taken together, these findings indicate that consumption of yeast hydrolysate-SR101 and eX Diet may lead to decreased body weight and fat.

구강악안면영역은 그 해부학적 구조상 혈관 분포가 풍부하고 따라서 구강내로 접근하는 수술시 신체 다른 부위와 달리 출혈 소견을 많이 보이며 수술중 과다출혈의 방지와 지혈의 목적으로 epinephirne soaked gauze즉 bosrnine gauze의 사용이 널리 이루어지고 있고 또한 사용이 불가피하다고 할 수 있다. 그러나 이 부분은 혈관 분포가 풍부하므로 epinephrine의 systemic uptake의 가능성 또한 존재한다 할 수 있겠다. 고농도의 epinephrine은 이론상 혈관수축을 일으켜 순간적인 systemic volume overload의 상태를 야기시켜 폐부종 및 pulmonary effusion을 일으킬 수 있으나 아직까지 보고된 바 없었다. 악안면부위는 혈관공급이 많아 수술중 지혈이 용이하지 못해 bleeding control을 위해 또 습관적으로 bosmine 거즈의 packing이 행해지고 있지만 수술자에 의한 정확한 농도로 희석된 bosmine 거즈 사용이 필수적이다. 본원에서 양악 악교정 수술시 소독간호사에 의해 잘못 희석된 고농도의 bosmine 거즈를 상악후방에 packing하여 발생된 전신적 합병증으로써 폐부종이 발생한 바 bosmine 거즈의 사용시 사용부위에 따라 농도의 확인과 술자의 주의를 요한다고 생각된다.

치주질환(periodontal disease, 잇몸병)은 인구의 50%이상이 이환되는 만성질환이다. 치주질환을 치료하지 않으면, 치아 지지조직의 염증을 악화시켜 치아손실(tooth loss)을 가져온다. 고혈압은 성인의 30%에서 발병하며, 심혈관계통 질환의 이환(morbidity)과 사망(mortality)의 중요한 원인이다. 약 20년 전까지만 해도 두 가지 질환은 깊은 관련이 없어 보였지만, 최근 서로 연관성이 있다는 사실이 밝혀졌다. 심혈관계통의 위험요소에 대한 연구결과, 죽상경화증(atherosclerosis) 합병증 발생은 치주(periodontium) 질환과 관계가 있다. 즉, 뇌졸중(stroke), 관상동맥질환, 말초동맥질환에 대한 위험요소가 치주염이라는 증거가 있다. 이런 인과관계는 두 가지 질환이 서로 공통의 위험요소를 갖는다는 의미이다. C-reactive protein(CRP)은 치주염에서 증가하고, 치주질환 환자는 혈관운동 기능(vasomotor function)이 손상된다는 보고가 있었으며, 치주질환으로 인해 고혈압이 발생한다. 본 연구의 목적은 문헌 고찰을 통해, 치주염과 고혈압을 비롯한 심혈관계통 질환의 인과관계를 밝히고자 한다. 고혈압은 당뇨와 함께 대표적인 생활습관질병이기 때문에, 본 연구를 통해서 적절한 치아관리를 통해 고혈압으로 인한 여러 가지 합병증을 예방하고자 한다.
