Objectives : This study was performed to investigate the inhibitory effects of Cheongshimyeonja-tang water extracts(CSYJ) on high fat diet-induced obesity and hyperlipidemia in C57BL/6J mice. Methods : The experimental animals were divided into four groups; normal diet-fed control(ND), high fat diet-fed control(HFD), HFD+CSYJ 150 mg/kg(CSYJ 150), and HFD+CSYJ 300 mg/kg(CSYJ 300). Obesity with hyperlipidemia was induced by feeding high fat diet(40%), and CSYJ was administrated orally into mice every day for 5 weeks. The effect of CSYJ on the serological parameters for Obesity with hyperlipidemia was evaluated. Results : CSYJ-treated groups revealed significantly reduced body weight and feed intake, as well as feed efficiency ratio, compared to HFD-fed group in dose-dependent manner. CSYJ reduced significantly the serum levels of triglyceride, total cholesterol and LDL-cholesterol elevated by intake of high fat diet feed, while the increased serum levels of HDL-cholesterol attenuated levels of atherogenic index and cardiac risk factor. It also reduced the blood levels of insulin and leptin in HFD group, and inhibited lipid accumulation in organs such as liver and abdomal adipose tissue. Moreover oral administration of CSYJ decreased significantly the blood level of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and lactate dehydrogenase(LDH), and lipid peroxide(LPO), compared to HFD-fed group in dose-dependent manner. Conclusions : These results indicate that CSYJ could reduce high fat diet-induced obesity and hyperlipidemia, suggesting its clinical usefulness for declining body fat and hyperlipidemia.

Background and Aims: Dansamtongmek-tang (DSTMT) and Dansamsengmek-san (DSSMS) have been used for many years as therapeutic agents for the acute stage of cerebrovascular disease, hypertension and hyperlipidemia in Oriental medicine, but the effects of DSTMT and DSSMS on hyperlipidemia and safety for cell damage are not yet well-known. This study was done to investigate the effects of DSTMT and DSSMS on hyperlipidemia. Methods: In vivo test: after administering DSTMT and DSSMS to SHR and ICR occurred hyperlipidemia for 3 weeks, we analyzed body weight, cholesterol levels. TG, HDL-chol, LDL-chol, LDH in plasma, brain, liver and kidney tissue, and DNA by RT-PCR. In vitro test: after administering DSTMT and DSSMS to human hepatocellular carcinoma in hypoxia, we observed cell cohesion by light microscope, analyzed the inflow of Ca2+ by confocal laser scanning microscope and DNA by RT-PCR. Results: DSTMT significantly decreased the levels of triglyceride and increased the levels of HDL-cholesterol in SHR, and significantly decreased the levels of LDL-cholesterol and body weight and increased the levels of HDL-cholesterol in ICR. DSSMS significantly decreased body weight, total cholesterol levels, LDL-cholesterol, LDH and cardiac risk factor (CRE) in SHR and significantly decreased the levels of total cholesterol, triglyceride, LDL-cholesterol, LDH and CRF in ICR. DSTMT had an effect on protecting cells from damage by inhibiting production of p53 mRNA, and in DSSMS, by inhibiting production of p53 mRNA and p21 mRNA after hypoxia. DSTMT effectively blocked off Ca2+ at low density, but DSSMS effectively blocked off Ca2+ at high density. Both DSTMT and DSSMS had an effect on inhibiting lipid metabolism by blocking off production of apo B mRNA. Conclusions: These results suggest that DSTMT and DSSMS might be usefully applied for treatment of hyperlipidemia and suppression of brain damage.

To evaluate of biological activity of Chambirum ($Amaranthus$ $lividus$) $in$ $vitro$ and $in$ $vivo$, we investigated the free radical scavenging activity of its extracts $in$ $vitro$ and the effect of lyophilized powder on the serum lipid profile of rats fed cholesterol. ABTS, DPPH, and NO radical scavenging activities were tested from water and 80% ethanol extracts of Chambirum, and biological activities of the ethanol extracts were significantly higher than the water extracts. The total lipid and total cholesterol content of serum, atherogenic index (AI), and cardiac risk factor (CRF) were decreased significantly for the groups fed with a 5% and 10% supplement of Chambirum powder (HCA1 and HCA2) in comparison with the group fed cholesterol (HC). Triglyceride content decreased drastically in the HCA2 group, while its content was not decreased in the other group. HDL-cholesterol content was elevated in the HCA1 and HCA2 groups, but was not significantly different to the supplemented amount of Chambirum powder. GPT and ${\gamma}$-GTP activities were decreased significantly in the groups fed with Chambirum powder compared to the HC group. And the content of the lipid peroxide level was the same trend. Therefore, these results give evidence that Chambirum might be useful in the control of induced disorders by dietary cholesterol and/or lipids.

Hypertension is the most prevalent disease worldwide and is itself a risk factor for cerebral, cardiac, and renal diseases. The inconsistency of candidate genes suggested by previous genomewide association studies (GWASs) may be due to not only differences in study design and genetic or environmental background but also the difference in the power of analysis between continuous traits and discrete traits. We analyzed 352,228 single nucleotide polymorphisms (SNPs) in 8842 unrelated Koreans obtained from Ansan and Ansung cohorts. We performed a series of GWA analyses using three different phenotype models; young hypertensive cases (278 subjects) versus elderly normotensive controls (680 subjects); the upper 25% (2211 hypertensive cases) versus the lower 25% of the SBP distribution (2211 hypotensive controls); and finally SBP and DBP as continuous traits (8842 subjects). The numbers of young hypertensive cases and elderly normotensive controls were not large enough to achieve genomewide significance. The model comparing the upper 25% subjects to the lower 25% of subjects showed a power that was approximate to that of QTL analysis. Two neighboring SNPs of the ATP2B1 gene, rs17249754 (SBP, p=$2.53^{-10}$; DBP, p=$1.28{\times}10^{-8}$) and rs7136259 (SBP, p=$1.30{\times}10^{-9}$; DBP, p=$6.41{\times}10^{-8}$), were associated with both SBP and DBP. Interestingly, a SNP of the RPL6 gene, rs11066280, revealed a significant genomewide association with SBP in men only (p=$3.85{\times}10^{-8}$), and four SNPs located near the MAN2A1 gene showed a strong association with DBP only in elderly men aged 60-70 years (e.g., rs6421827, p=$4.86{\times}10^{-8}$). However, we did not observe any gene variant attaining genomewide significance consistently in the three phenotype models except for the ATP2B1 gene variants. In general, the association signal with blood pressure was stronger in women than in men. Genes identified in GWASs are expected to open the way for prevention, early diagnosis, and personalized treatment of hypertension.

This study was perfomed to investigate the effects of Chunghyul-plus(CHP) on oxidative damage and hyperlipidemia in db/db mouse. After treatment with CHP, safety in cytotoxicity, heavy metal toxicity, production of reactive oxygen species(ROS), nitric oxide (N0) and proinflammatory cytokine IL-Ib, TNF-a, IL-6 in RAW 264.7 cells. Serum total cholesterol, LDL cholesterol, HDL cholesterol, triglyceride, insulin, GLP-1, glucose, food intake, body weight, organ weight, AST, ALT, ALP, BUN, creatine and histologic change of liver and aorta were measured in db/db mouse after oral administration of CHP. CHP showed safety in cytotoxicity and toxicity of liver and kidney for logn time administration. CHP increased the DPPH and ABTS radical scavenging activity. CHP showed significant inhibitory effect on reactive oxygen species (ROS), and showed inhibitory effect on nitiric oxide(NO) compared to control group. CHP decreased cytokine IL-6 production significantly, and decreased IL-1β and TNF-α compared to control group. CHP decreased body and organ weitht, intake food, and glucose levels compared to control group. CHP decreased total cholesterol and triglyceride significantly, and decreased LDL-cholesterol levels and increased HDL-cholesterol levels compared to control group. CHP decreased atherogenic index and cardiac risk factor significantly. CHP increased serum insulin and GLP-1 compared to control group. In histologic examination, lipophagy in the liver and aorta decreased in CHP treated mice and the cell was regular and boundary of vessel wall was clear compared to control group. These results suggest that CHP is effective in antioxidation activity and treatment and prevention of hyperlipidemia, atherosclerosis, diabetes, ischemic heart disease, stroke and other cardiocerebrovascular disease.

Purpose : This study assessed the long term survival rate and long term complications of patients who had a modified Fontan operation for functionally univentricular cardiac anomaly. Methods : Between June 1986 and December 2000, 302 patients with a functional single ventricle underwent surgical interventions and were followed up until February 2006. The mean follow-up period was $8.3{\pm}5.3years$ (range 3.5-18 years). Their median age was 2.4 years at the Fontan operation. The survival rate, the incidence and the risk factor of late complications were evaluated retrospectively. Results : The verall survival rate was 91 percent at 5 years and 87 percent at 10 years. In multivariate analysis, early calendar year of operation and significant regurgitation were risk factors of death. The surviving patients showed NYHA functional class I in 82 percent, class II in 15 percent, and class III in 3 percent. Redo Fontan operations were necessary in 8.8 percent of patients at average $12.8{\pm}3.6years$ after initial Fontan operation. The most common cause of Fontan conversion was atrial arrhythmia. The incidence of thromboembolic events was 9.3% and these complications were associated with the occurrence of atrial tachyarrhythmia. Supraventricular tachycardia including atrial flutter or fibrillation were reported on the follow-up examination by 11.2 percent of survivors after $8.4{\pm}5.6years$. Atriopulmonary connection showed higher rates of late tachycardia than lateral tunnel operation. Conclusions : This study revealed that the recent survival rate of Fontan type operation was satisfactory, but the occurrence of late complications after a Fontan type operation increased with the longer survival. There is a need for strict follow up and early treatment of late complications in patients who had a Fontan operation.

Advanced age in Esophagectomy increases the risk of postoperative morbidity and mortality. However, the recent development of operative technique and perioperative care might have decreased the postoperative morbidity and mortality after esophagectomy. Material and Method: From March 2001 to July 2004, 174 patients underwent esophageal resection for esophageal cancer in the Center for Lung Cancer, National Cancer Center. The patients were divided into two groups : group 1 consisted of 27 patients aged 70 years or more, and group 2 consisted of 147 patients under 70 years of age. The two groups were compared according to preoperative risk factors, postoperative morbidity, operative mortality and survival. Result: The mean age was 63_4. There were 159 men. On histopathological examination, $93.1\%$ had squamous cell carcinoma. On the locations, $78.7\%$ were in mid and lower esophagus. Curative resections for esophageal cancer were possible in $162(93.1\%)$ patients. Mean hospital stay was 19.4 days with out difference between the groups. The overall postoperative morbidity were occurred in 61 patients $(35.1\%)$. The most frequent morbidity was pulmonary complication in $30(17.2\%)$. Preoperative incidence of hypertension, cardiac and pulmonary dysfunction were more common in Group I. However, there was no difference in overall postoperative morbidity, operative mortality and survival rate between the two groups. Conclusion: Esophagectomy for esophageal cancer could be carried out safely in patients over 70 years of age with satisfactory short-term results. Advanced age is no longer a risk factor for esophagectomy.

Purpose : Delineation of serum lipid and lipoprotein values in children after Kawasaki disease(KD) is important because of the predilection of this disease for the coronary arteries. Methods : The KD group was composed of 51 patients who were hospitalized from Jan. 2002 to Dec. 2003. Control was 25 patients with non-KD febrile illness. The levels of total lipid, phospholipid, triglyceride, HDL-cholesterol(HDL-C), LDL-cholesterol, total cholesterol, apolipoprotein A1(apo A1), apolipoprotein B, and Lipoprotein(a) were measured and compared with Echocardiographic findings. Measurements were obtained in four time periods: acute febrile, subacute, convalescent phase and 1 year after KD. Results : HDL-C($33.64{\pm}7.49mg/dL$ vs $50.43{\pm}14.41mg/dL$, P<0.01) and apo A1($99.75{\pm}6.39mg/dL$ vs $113.34{\pm}11.35mg/dL$, P<0.05) were decreased more in the acute febrile period of KD than in the control, but these changes were not correlated with cardiac complications. All lipid profiles were markedly elevated in the subacute stage and normalized in the convalescent stage; there were no changes until 1-year follow up. There were no significant differences in the changes of lipid profiles, including Lp(a) and coronary dilatation, in any time periods. Conclusion : KD is associated with important abnormalities in lipid metabolism, but these changes were transient and appear to be due to the disease itself. These data lead us to infer that KD dose not cause such permanent changes in lipid abnormalities as to be considered a risk factor for atherosclerosis, beyond that caused by the disease itself.

Background: The brain natriuretic peptide (BNP) level has been reported in some studies to be associated with the occurrence of atrial fbrillation (AF). The aim of this study is to evaluate the potential usefulness of the BNP level as a predictor of the occurrence of postoperative (postop) AF and to assess the relationship of the BNP level with the onset of AF and the restoration of sinus rhythm. Material and Method: From January 1, 2005 to February 28, 2006, 82 patients without a history of atrial arrhythmia that had undergone cardiac surgery were enrolled in the study. Blood samples for plasma BNP were drawn daily for all these patients from the preoperative (preop) day to the 7th postop day. The patient records were reviewed and postop EKGs were checked daily for AF until the time of discharge. Result: Patients were divided into two groups based on development of postop AF. Postoperative AF developed in 26 patients (31.7%). There was no significant statistical difference in age, sex distribution, preop left ventricle ejection fraction, hypertension, left ventricular hypertrophy, or the use of beta blockers between the non-postop AF and postop AF group. More patients in the AF group had undergone valve surgery (39.3% versus 76.9%, p=0.002). The preop left atrium size was significantly larger in the AF patients ($43.8{\pm}10.3 mm$ versus $49.8{\pm}11.5 mm$, p=0.029). The preop plasma BNP levels were higher in the postop AF patients ($144.1{\pm}20.8 pg/mL$ versus $267.5{\pm}68 pg/mL$, p=0.034). In the postop AF group, the plasma BNP level was the highest on the 3rd postop day. Postop AF developed in most patients by the 3rd postop day; restored sinus rhythm developed by the 7th postop day. Conclusion: Elevated plasma BNP levels may lead to the occurrence of postop AF in patients undergoing cardiac surgery. Patients who have a high risk of postop AF should be considered for aggressive prophylactic antiarrhythmic therapy.
