Background: Wet cupping (WC) is an efficient and cost-effective technique for removing metabolic waste from the bloodstream via the skin. The study aimed to examine the effect of WC on cholesterol levels including total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in a Sudanese population. Methods: In this prospective cross-sectional study, 30 participants undergoing regular WC therapy were enrolled. Blood samples collected twice: pre-WC therapy (case group) and 10-14 days afterward (controls). Results: Of the participants, 56.67% were male and 43.33% were female, aged 24-69. Pre-WC TC and LDL-C levels were significantly higher than the post-WC control group (p = 0.001). Conversely, HDL-C levels decreased significantly in the pre-WC cases compared to controls (p = 0.001). No significant sex-based difference in mean cholesterol levels (p > 0.05). Conclusions: After WC, males and females experienced significant reductions in TC and LDL-C, and significant increase in HDL-C.

The principal objective of this study was to assess the effects of chitosan oligosaccharide supplementation on the improvement of blood glucose, lipid components and enzyme activities in the serum of streptozotocin(STZ, 55 mg/kg B.W., I.P. injection)-induced hyperglycemic rats fed on experimental diets for 5 weeks. The concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free cholesterol, cholesteryl ester ratio, triglycerides(TG) and phospholipids(PL) in serum were remarkably higher in the hyperglycemic group(group BSW) and STZ(I.P.)+chitosan oligosaccharide supplementation group(group ECW) than those in the control group(group BW, basal diet+water). However the concentrations of blood glucose, total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, tree cholesterol, cholesteryl ester ratio, TG and PL in serum were lower in the ECW group than in the BSW group, whereas the ratio of HDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration in the ECW group were higher than in the BSW group. The activities of alkaline phosphatase(ALP) and aminotransferase(AST, ALT) in serum were lower in the ECW group than in the hyperglycemic BSW group. The results shown above suggested that chitosan oligosaccharide supplementation effectively improves blood glucose, lipid composition and enzyme activities in the sera of STZ-induced hyperglycemic rats.

KJST is the oriental herbal medicine of hyperlipemia which consisted of a herb of 17. We induced hyperlipemia to Spontaneous Hypertensive Rat(SHR) and studied the treatment effect by KJST. Hyperlipidemia was induced by hyper-lipidemic diet fed for 4weeks. Total cholesterol, LDL-cholesterol, HDL-cholesterol, Triglyceride, Total bilirubin, Lactic dehydrogenase(LDH), Glucose and Total protein were measured on the serum after an oral administration of KJST. Total cholesterol, LDL-cholesterol, Glucose and LDH was significantly lower in the KJST treated animals, and HDL was significantly raised in the KJST treated animals. These results suggest that KJST is effective for the treatment of hyperlipidemia.

This study showed the effect of fermented milk on the cholesterol level of Korean. 130 persons among the teachers of elementary, middle and high schools, professors and graduate school students were divided into two groups according to their cholesterol level and provided with fermented milk 300 $m\ell$ dairly from Sep.25 to No. V3. They were given blood test at 20 days and 40 days after drinking fermented milk, and surveyed about their ordinary life style and the change of fecal condition. Cholesterol, LDL and the ratio of LDL and HDL in blood were significantly decreased in both high cholesterol group and normal group while HDL cholesterol was notably increased. TG showed slightly tendency of decrease in normal group while no changed in high group. There is no significant change in cholesterol level after drinking fermented milk among groups which are divided by factors of dringking, smoking, caffeine, B.M.I. and family history. The research also showed that drinking fermented milk improved the fecal frequency and fecal condition.

Low-density lipoprotein cholesterol (LDL-C) is a major modifiable risk factor for cardio- cerebrovascular disease. In clinical practice, however, it is primarily calculated using the Friedewald formula as a cost-effective method. The aim of this study was to compare Friedewald-estimated and directly measured LDL-C values and assess the concordance in guideline LDL-C risk classification between the two methods. The data were derived from the 2009 and 2010 Korea National Health and Nutrition Survey (KNHANES). Analysis was done for 4,319 subjects with lipid panels-total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), directly measured LDL-C using an enzymatic homogeneous assay, and triglycerides (TG). For subjects with TG lower than 400 mg/dL, Friedewald-estimated and directly measured LDL-C were highly correlated (r = 0.958, p < 0.001) and overall concordance was 82.7%. As TG increased, overall concordance decreased. Overall concordance was 85.4% at TG lower than 150 mg/dL; 78.2% at TG of 150-199 mg/dL; and 71.4% at TG of 200-399 mg/dL. The Friedewld equation tended to overestimate LDL-C when TG are of < 150 mg/dL; however, underestimate LDL-C when TG are of ${\geq}150mg/dL$. As a result, Friedewald estimation misclassified 382 subjects (9.1%) in a higher category versus 348 subjects (8.3%) in a lower category. Our findings suggest that overestimation of LDL-C by the Friedewald formula can be a great problem as well as underestimation.

The effect of low molecular alginates feeding on the cholesterol levels and fatty acid compositions of rat serum and liver lipid were investigated. After one week basal diet feeding, four week old Sprague-Dawley male rats were fed with water soluble and acid $\cdot$alkali soluble alginate extracted from sea mustard (Undaria pinnatifida) and giant kelp (Macrocystis pyrifera), and their low molecular alginates prepared by the HCl partial hydrolysis. The feeding efficiency of the alginate fed group was ranged in 0.37$\~$0.44, which was 0.03$\~$0.05 lower than that of the basal diet group. Also, there was much less increase of liver weight in the alginate fed group. The water soluble alginate showed more significant effect in reducing the total cholesterol, free cholesterol, LDL-cholesterol, triglyceride and phospholipid of serum and liver lipid than the acid$\cdot$alkali soluble alginate. The effect was much better with low molecular alginate (reducing effect by the low-molecularization : Water soluble alginate - serum lipid; total cholesterol $59\%$, free cholesterol $65\%$, LDL-cholesterol $96\%$, triglyceride $50\%$, and phospholipid $36\%$. liver lipid: total cholesterol $4\%$, free cholesterol $62\%$, LDL-cholesterol $44\%$, triglyceride $33\%$, and phospholipid $44\%$. acid$\cdot$alkali soluble alginate - serum lipid; total cholesterol $52\%$: free cholesterol $97\%$, LDL-cholesterol $78\%$ triglyceride $32\%$, and phospholipid $64\%$. liver lipid; total cholesterol $11\%$, free cholesterol $12\%$, LDL-cholesterol $10\%$, triglyceride $27\%$, and phospholipid $21\%$). The effect of low molecular alginate feeding on the fatty acid composition of serum and liver lipid reflects the remarkable increase of polyenoic acid, over $44\%$ in serum lipid and about $70\%$ in liver lipid, comparing to the cholesterol fed group. The overall results indicated that feeding of low molecular alginates improves physiological function of rats by changing the serum and liver lipid composition.

To examine the association of hypertension with cluster of obesity, abnormal glucose and dyslipidemia in Korean urban population, we conducted this cross-sectional study among 3027 men and 2127 women age 20-85 years who visited a prevention center between May 1991 and June 1995 for a multiphasic health check at St. Mary's Hospital, Seoul. By the self-administered questionnaire, the informations of educational attainments, monthly income, alcohol consumption, cigarette smoking, and physical excercise level were obtained. Height, weight, and blood pressure were measured by a trained nurse. The fasting blood sugar (FBS), total cholesterol, high density lipoprotein (HDL) cholesterol and triglyceride were tested by enzyme method. Low density lipoprotein (LDL) cholesterol was calculated by 'total cholesterol - HDL cholesterol - triglyceride/5'. For testing the differences of cardiovascular risk factors between hypertension and normotension group, 1-test and $\chi^2$-test were performed. For the age adjusted odds ratios of hypertension in persons with obesity, abnormal glucose, and dyslipidemia compared with normal, logistic regression was performed by using SAS pakageprograme. The results obtained were as follows: 1. Age, weight, body mass index(BMI), blood glucose, total cholesterol, LDL cholesterol, and triglyceride of hypertension group in men and women were significantly higher than normotension group, but height and HDL cholesterol of hypertension group only in women significantly lower than normotension group. The frequency of obesity $(BMI\geq25kg/m^2)$, abnormal glucose $(\geq\;120mg/dl)$, hypercholesterolemia $(\geq\;240mg/dl)$, lower HDL cholesterol (<45 mg/dl in women only), higher LDL cholesterol $(\geq\;160mg/dl)$, and hyper hypertriglyceridemia $(\geq\;250mg/dl)$ in hypertension group of men and women were significantly higher than normotension group. 2. Systolic and diastolic blood pressure were negatively correlated with hight, but positively with age, weight, BMI, total cholesterol, LDL cholesterol, and triglyceride in men and women. BMI was positively correlated with fasting blood sugar, total cholesterol, LDL cholesterol and triglyceride but negatively with HDL cholesterol. 3. The age adjusted odds ratios of hypertension were as follows in men and women : among persons who were obese compared with those nonobese, 2.53 (95% Confidence Intervals [C.I.] 2.08-3.07) and 2.22 (95%C.I. 1.71-2.87): among persons who were abnormal glucose compared with those normoglycemic, 1.43 (95%C.I 1.13-1.82) and 2.01 (95%C.I 1.36-2.94): and among persons who were dyslipidemia (hypercholesterolemia or lower HDL cholesterol or higher LDL cholesterol or hypertriglyceridemia) compared with those normal lipid, 1.59 (95%C.I 1.30-1.95) and 1.51 (95%C.I 1.16-1.96). After combined more than one risk factor, the odds ratios were increased. Among persons with cluster of obesity, abnormal glucose, and dyslipidemia, the odds ratio of hypertension was 2.25 (95%C.I 1.47-3.37) in men and 3.02 (95%C.I 1.71-5.30) in women. In conclusion, it was suggested that hypertension was associated with cluster of obesity, abnormal glucose, dyslipidemia in this Korean urban population.

The present study examined the effect of soy isoflavones on lipid metabolism in growing female rats. Rats were randomly assigned to three different groups and provided experimental diets for 9 weeks. The experimental groups were classified into 1) a control group, 2) a soy protein isolate group: soy (+)) group and 3) a soy protein concentration group: soy (-)) group. Diets contained either casein or one of two soy proteins with (soy (+)) or without isoflavones (soy (-)). Serum triglyceride concentration showed no significant differences among the experimental groups. Serum total cholesterol concentration was significantly lower in both the soy (+) and soy (-) groups than in the control group and LDL-cholesterol concentration was significantly lower in the soy (+). Serum HDL-cholesterol concentration was significantly higher in the control group than in the soy protein groups but the HDL-cholesterol share rate in total cholesterol tended to be lower in the control group than in the soy protein groups, insignificant as it was. Hepatic IDL receptor mRNA level was significantly increased in the soy (+) group when compared to the other two groups to be 20% higher than the control group. In conclusion, soy protein isolate, soy protein rich with isoflavones reduced serum total cholesterol and LDL-cholesterol concentration and increased hepatic IDL receptor mRNA expression in growing female rats. Therefore, it is considered that the intake of soy isoflvones during puberty can be advantageous in terms of the long-tenn control of serum lipid.

The effect of ginsenoside-Rb2, one of a major pharmacological component of Panax ginseng C.A. Meyer, on low density lipoprotein (LDL) receptor expression was investigated and compared with hypocholesterolemic drug lovastatin. In HepG2 cell, exogenous cholesterol decreased LDL receptor mRNA expression, but ginsenoside-Rb2 recovered this reduction of LDL receptor mRNA up to normal expression level. Lovastatin also increased LDL receptor mRNA expression as similar as ginsenoside-Rb2 did. The reduction of sterol regulatory element binding protein (SREBP) transcription by exogenous cholesterol was also similarly recovered by ginsenoside-Rb2 and lovastatin addition. Compound K, a metabolite of ginsenoside-Rb2 and -Rb1 by human intestinal bacteria also increased the SREBP mRNA expression in cholesterol-enriched condition. Ginsenoside-Rb2 seems to up-regulate LDL receptor mRNA expression through the induction of de novo SREBP transcription. Therefore, increased expression of SREBP mRNA by ginsenoside-Rb2 elevated the LDL receptor mRNA expression in HepG2 cells, and these inductions possibly drop the plasma cholesterol level in hypercholesterolemia patients, in vivo, as likely in case of lovastatin.

Hypercholesterolemia is one of main causes of coronary heart disease(CHD). Clinical trials demonstrated that lowering serum cholesterol levels would reduce incidence of new cardiovascular events and mortality by primary or secondary preventions. The objective of this retrospective study was to compare efficacy and side effects of lovartatin and simvastatin in treatement of hypercholesterolemia. In Boramae Hospital, patients were included when they have taken lovastatin 20 mg or simvastatin 10 mg for 52 weeks with laboratory monitoring for cholesterol at baseline, 3, 6 and 12 month period. As results, total 128 outpatients were included with their total cholesterol level <240 mg/dl and triglyceride level <400 mg/dl at baseline. Total cholesterol and LDL cholesterol of lovastatin group (n=60) and simvastatin group (n=68) were significantly reduced from baseline (p=0.001). Lovastatin maximally reduced total cholesterol by $23.9\%,\;triglyceride\;by\;12.3\%$, LDL cholesterol by $36.1\;\%$ and increased HDL cholerterol by $7.8\%$ and simvastatin reduced by $24.1\%,\;20.5\%,\;34.3\%\;respectively$ and HDL increased by $11.2\%$. There were no significant differences between lovastatin and simvastatin in mean percent change of lipid levels at 12, 24 and 52 weeks from baseline. Cumulative percentage of patients reaching the target LDL cholesterol concentration by 24 weeks was $61.7\%$ in lovastatin and $64.7\%$ in simvastatin. Average time to reach the target LDL goal was 100.1 days in lovastatin and 99.8 days in simvastatin. Both lovastatin and simvastatin also significantly reduced total cholesterol and LDL cholesterol in all subgroups (diabetes mellitus, hypertension, and coronary heart disease). In this study, treatment efficacy in patients with coronary heart disease was lower than other patients. Considering clinical importance of secondary prevention, more intensive treatment is necessary to decrease LDL cholesterol level of 100 mg/dl or lower in patients with coronary heart disease or other clinical atherosclerotic disease. There were no serious side effects during the study period. Digestive side effects were most frequently reported (lovastatin $8.3\%\;vs\;simvastatin\;8.8\%$). In conclusion, both lovastatin and simvastatin were similar in lipid lowering effects and there was no difference in incidence of side effects.
