Objectives: This study was designed to examine the effects of extracts of Ojeoksangamibang($W{\check{u}}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) on the lipid lowering, anti-oxidation and concentration of proinflammatory cytokines and was investigated on hyperlipidemic rats. Methods: Male rats weighing $182.39{\pm}4.71g$ were fed high fat diet for 8 weeks and 36 rats(above 400 g) were divided into 4 groups. Each of 9 rats was divided a control group and experimental groups. We fed a control group of rats a basal diet and administered normal saline(100 mg/kg, 1 time/1 day) for 4 weeks. And we fed each experimental group of rats basal diet and administered an extract of Ojeoksangamibang($W{\check{u}}j\bar{i}s\check{a}nji\bar{a}w\grave{e}if\bar{a}ng$) extracts(100 mg/kg, 200mg/kg, 300 mg/kg, 300 mg/kg, 1 time/1 day) for 4 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. We measured lipid of plasma and liver, concentration of proinflmmatory cytokines, anti-oxidative activity and $TNF-{\alpha}$, Apo-B, Apo-E and leptin gene expression. Results: 1.

Background: Thoracic outlet syndrome(TOS) is caused by the compression of neurovascular structures that supply to the upper extremities. Only a few reports have been published in Korea, and this study attempts to investigate the clinical aspects and results of the patients who underwent surgical treatment. Material and Method: This study consist of 16 patients who underwent operations for thoracic outlet syndrome from May, 2002 to October, 2004. The surgical indications were confined to patients with: 1) symptom too severe to perform ordinary daily life because of pain, paresthesia, edema of upper extremities, 2) no improvement after proper physical therapy, 3) definite finding of compression confined by radiologic examinations (MRI, angiography, etc), and 4) no other diseases such as cervical intervertebral herniation, myositis, neurologic diseases below the brachial plexus. The surgical approaches were by transaxillary approaches in 12 cases, supraclavicular approaches in 2 cases, and infraciavicular approaches in 2 cases. Result: There were 15 males and one female with an average age of 23.9 years (range:19$\∼$39). Rib anomalies were observed in four cases (25.0$\%$), but the others had no abnormal ribs. Right lesions were found in eight cases (50.0$\%$), left lesions in five cases (31.3$\%$), and bilateral lesions in three cases (18.7$\%$). The follow-up period was 9$\∼$26 months and recurrence rate was 12.5$\%$ (2/16). Complications were one case of ulnar nerve palsy, one case of persistent pain despite radiologic improvement and three cases of wound dehiscence due to fat necrosis and hematoma. Conclusion: Although the choice of treatment in patients with TOS has been disputed, patients who have no response with proper physical therapies can benefit from the surgical treatment which may help patients to return to normal daily activity in shorter period of time.

Background : Unexplained weight loss, which commonly occurs in patients with chronic obstructive pulmonary disease(COPD), is important because weight loss is an independent risk factor of mortality and morbidity in these patients. Leptin is known to play an important role in regulating body weight. In addition, the tumor necrosis factor($TNF-{\alpha}$) might also play a potential role in the weight loss experienced in chronic wasting disease. The aim of this study was to determine the influence of plasma leptin and the circulating $TNF-{\alpha}$ system to the difference in the body compositions in patients with COPD. Methods : Spirometry, body composition analysis and the plasma concentrations of leptin, $TNF-{\alpha}$ and a soluble TNF receptor (STNF-R55, -R75) were measured in 31 patients with chronic bronchitis and 10 patients with emphysema. The COPD subtype was classified by the transfer coefficient of carbon monoxide, DLco/VA. Results : The circulating levels of leptin were significantly lower in those patients with emphysema($108.5{\pm}39.37pg/ml$) than those with chronic bronchitis($180.9{\pm}57.7pg/ml$). The circulating levels of sTNF-R55 were significantly higher in the emphysema patients($920.4{\pm}116.4pg/ml$) than in those with chronic bronchitis($803.2{\pm}80.8pg/ml$). There was no relationship between the circulating leptin levels and the activated TNF system in patients with chronic bronchitis and emphysema. However, the circulating leptin levels correlated well with the BMI and fat mass in both patient groups. Conclusion : These results suggest that the weight loss noted in emphysema patients may be associated with the activation of the $TNF-{\alpha}$ system rather than the plasma leptin level.

The objective of this study was to investigate the effects of a lettuce (Lactuca sativa L.) extract on the inflammation of human umbilical vein endothelial cell (HUVEC) and blood lipid improvement in hypercholesterolemic mice fed a high cholesterol diet. The lettuce extract (100% ethanol extract) inhibited the expression of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 in HUVEC treated with tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). The lettuce extract suppressed the adhesion of THP-1 to TNF-${\alpha}$-treated HUVEC. The lettuce extract decreased the TNF-${\alpha}$-stimulated production of proinflammatory cytokine interleukin-6, interleukin-8 and chemokine monocyte chemotactic protein 1. In hypercholesterolemic mice, the lettuce extract reduced serum total cholesterol, triglyceride, and low-density lipoprotein-cholesterol level, while the lettuce extract elevated high-density lipoprotein-cholesterol level, resulting in the decrease of atherogenic index and cardiac risk factor level. These results suggested that lettuce extract can be an useful resource to show an anti-inflammatory effect and improve lipid metabolism.

This study was conducted to determine the effects of vitamin C on the activity of liver function enzymes and electromicrographic changes in white rats treated with aflatoxin $B_1(AFB_1)$ or X-ray and $AFB_1$. Six week-old male Sprague-Dawley rats were randomly divided into five groups: a control group, $AFB_1$ treated group, $AFB_1$ treated group with vitamin C, X-ray and $AFB_1$ co-treated group, X-ray and $AFB_1$ co-treated group with vitamin C. On the first day of the experiment, only one dose of X-rays was exposed to the entire liver at 1,500 cGy. Next, vitamin C was injected at 10 mg/kg body weight by intraperitoneal injection, followed 1 hr later by the administration of 0.4 mg/kg of $AFB_1$ by intraperitoneal injection. These treatments were then administered every three days over a period of 15 days. On the 16th day of treatments, the animals were sacrificed. Analysis of the activity of the liver function enzymes, GOT, ALK phatase and LDH, in the sera of rats revealed that they were somewhat increased by $AFB_1$ treatment, X-ray and $AFB_1$ co-treatment when compared to the control group. Furthermore, the activity of these enzymes decreased in response to administration of vitamin C. Especially, the levels of GOT were remarkably decreased in the $AFB_1$ treated group treated with vitamin C when compared to the group treated with $AFB_1$ alone(p<0.001). Electromicrographic analysis revealed cloudy swelling, necrosis, vesicular degeneration and fat accumulation of hepatocytes in response to treatment with $AFB_1$ or co-treatment with X-ray and $AFB_1$. However, the destruction of hepatic cells was considerably lower in the vitamin C-treated group. These results indicate that vitamin C had ameliorating effects on the hepatic cell damage.

This study was carried out to investigate the anti-oxidative and anti-inflammatory actions of Hericium erinaceus mycelia in BALB/C mice injected with lopopolysaccharide (LPS), called endotoxin. Mice (6 weeks of age) weighing approximately $24.73\pm0.11$ g were divided into 5 groups and were fed on the experimental diets containing Hericium erinaceus mycelia powder (HMP) for 1 week. Experimental groups were NC (normal control), HMP-C (HMP control), LC (LPS control), HMP 3%, and HMP 10%. Endotoxin shock was induced by intraperitoneal injection of LPS (100 mg/kg BW). NC and HMP-C groups were injected with saline solution (100 mg/kg BW). Food efficiency ratio were significantly (p<0.05) decreased in the HMP supplementation groups. Total fat and $\beta$-glucan excretion were higher in HMP supplementation groups than NC and LC groups, while plasma TG level was not different among groups. Plasma ALT levels were significantly (p<0.05) lower in the HMP supplementation groups than in LC group at 8 hr after LPS injection, while tumor necrosis factor-$\alpha$ and interleukine-6 levels of plasma were not different among groups. Hepatic superoxide dismutase, glutathione-reductase (GSH-red), and glutathione-peroxidase activities were higher in the HMP supplementation groups than in LC group at 4 hr after intraperitoneal injection of LPS. Hepatic GSH levels and protein expression of GSH-red was significantly (p<0.05) higher in the HMP supplemented groups than in LC group at 1 hr, 4 hr and 8 hr after LPS injection. From the above results, it is concluded that Hericium erinaceus mycelia may ameliorate hepatic oxidative stress by LPS through the elevation of hepatic glutathione level and antioxidant enzyme activities, which support the hepatoprotective effect of Hericium erinaceus mycelia.

Purpose: Since there are few studies involving acute pancreatitis in children, we reviewed our experience with this medical condition to describe the clinical features. Methods: A retrospective analysis was conducted by reviewing the medical records of 41 patients with AP who were admitted to the Department of Pediatrics of Pusan National University Hospital between January 1996 and June 2007. Results: Twenty males and 21 females (mean age, 8.7${\pm}$4.5 years) were included. In 22 patients (53.7%), no definitive causes were found. The most common etiologies were choledochal cysts (22.0%). Necrotizing pancreatitis was diagnosed in 5 patients (12.2%), and recurrent acute pancreatitis in 4 patients (9.8%). CT findings included pancreatic swelling (43.9%), peripancreatic fluid collection (29.3%), ascites (24.4%), and peripancreatic fat necrosis (12.2%). Serum amylase and lipase levels at diagnosis were 535.3${\pm}$553.2 and 766.2${\pm}$723.6 U/L, respectively, and were normalized within 1 week in 22 and 14 patients, respectively. On the basis of the Balthazar scale, 2 patients were diagnosed with severe AP. In 4 patients (9.8%), a surgical procedure was indicated. Major complications included ascites (32.3%), sepsis (16.1%), and pseudocyst and renal impairments (12.9%). Two patients died from multi-organ failure. Conclusion: The etiologies of AP in children are varied. Most children have a single episode and a self-limited course. However, AP of childhood still carries significant morbidity and mortality. Early diagnosis, appropriate treatment according to disease severity, and management of complications are important.

In the present study, we comprehensively examined the associations of plasma levels of total adiponectin and high molecular weight (HMW) adiponectin with the features of cardiometabolic risks including body fat distribution, dyslipidemia, insulin resistance and inflammatory markers in a cross-sectional study of 110 treated hypertensive patients. Blood lipid profiles, high sensitivity C-reactive protein (hsCRP) and homeostasis model assessment of insulin resistance (HOMA- IR) derived from fasting glucose and insulin concentrations were determined. Plasma levels of tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$), interleukin-6 (IL-6) and intercellular adhesion molecule-1 (ICAM-1) were analyzed using ELISA. The results showed that plasma levels of HMW-adiponectin were negatively associated with body mass index (BMI, r = - 0.203, p < 0.05) and waist circumference (r = -0.307, p < 0.01), which was not shown in total adiponectin. Plasma levels of HMW-adiponectin were negatively associated with triglyceride (r = -0.223, p < 0.05) and positively associated with HDL-cholesterol (r = 0.228, p < 0.05). Plasma levels of adiponectin were positively associated with HDL-cholesterol (r = 0.224, p < 0.05). Plasma levels of HMW-adiponectin were negatively associated with hsCRP (r = -0.276, p < 0.01) and IL-6 (r = -0.272, p < 0.01). In addition, there were weak associations between plasma levels of HMWadiponectin and TNF-${\alpha}$ (r = -0.163, p = 0.07) and ICAM-1 (r = -0.158, p = 0.09). However, there were no significant associations of total adiponectin with inflammatory markers except hsCRP (r = -0.203, p < 0.05). Stepwise multiple linear regression analysis showed that only plasma levels of HMW-adiponectin was an independent factor influencing serum levels of hsCRP, a marker of systemic low grade inflammation, after adjusting for age, gender, BMI, waist circumference, alcohol intake, smoking status, blood lipids, total adiponectin and drug use (p < 0.01). These results suggest that HMW-adiponectin, rather than total adiponectin, is likely to be closely associated with the features of cardiometabolic risks in treated hypertensive patients and might be effective biomarker for the prediction of cardiovascular disease.
