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.

본 연구는 어성초 함유 한방원료의 지질대사 기능을 가진 한방차를 개발하는데 도움을 줄 목적으로 LPS로 간독성이 유도된 흰쥐에서 어성초에 오미자, 구기자, 사상자, 음양곽을 혼합해서 추출하고 이 혼합 추출물이 지질대사에 미치는 영향을 관찰하였다. 본 실험에서는 어성초 90g, 복분자 1g, 사상자 3g, 구기자 2g, 음양곽 4g을 혼합하고 추출하여 감압 농축하여 실험 샘플로 사용하였으며 생후 7주 암컷 흰쥐를 총 21마리를 7마리씩 3군으로 나누었고 군별로 cage에 분리시키고 고형사료와 물을 자유롭게 섭취하도록 하였다. 정상군은 20일 동안 1.5 ml/kg of 0.9% saline을 투여하고 대조군은 20일 동안 1.5 ml/kg of 0.9% saline을 매일 투여한 후 21일째 되는 날 LPS를 5 mg/kg의 농도로 만들어 1.5 ml/kg의 용량으로 복강 내로 투여하였다. 시료군(HM)에는 100 mg/kg농도의 각각의 분획을 1.5 ml/kg씩 복강 내에 20일간 매일 투여하고 21일째 되는 날에 LPS를 1.5 ml/kg의 용량을 복강 내로 투여하였다. LPS를 투여하고 절식시킨 뒤 4시간 후에 ether로 마취하고 해부하여 혈액을 채취하고 간을 적출하여 실험하여 다음과 같은 결과를 얻었다. Total-lipid 수준에서는 LPS를 투여한 대조군이 정상군에 비교하여 1.7배 증가하였으며 대조군과 비교해 HM군은 66.30% 감소하였다. Total-cholesterol 수준에서는 LPS를 투여한 대조군이 정상군에 비교하여 약 2 1배 감소하여 LPS로 간에 염증이 유발하여 total cholesterol의 수치가 감소하는 것을 확인하였으며 HM군이 대조군에 비교하여 41.13%의 수치로 회복하였다. HDL-cholesterol 수준에서는 LPS를 투여한 대조군이 정상군에 비교하여 약 2.3배 감소하였으며 HM군이 대조군에 비교하여 72.61%의 수치로 회복하였다. LDH 수준에서는 LPS를 투여한 대조군이 정상군에 비교하여 약 5.8배 증가하였으며 HM군이 대조군에 비교하여 68.91%의 수치로 감소하였다. TG의 수준에서도 LPS를 투여한 대조군이 정상군에 비교하여 약 3.8배 증가하였으며 HM군이 대조군에 비교하여 101.14%의 수치로 감소하였다. MDA는 LPS를 투여한 대조군이 정상군에 비해서 약 3.5배 정도로 높게 나타났고 HM군은 대조군에 비해 58.65%의 감소효과를 보였다. LPS가 간에 염종을 유발하여 혈청 속의 total-cholesterol과 HDL-cholesterol level이 감소하고 total-lipid와 LDH, TG의 수준이 증가한 것으로 사료되며 대조군에 비교하여 HM군이 혈청 속의 total-cholesterol과 HDL-cholesterol level을 증가시키고 total-lipid와 LDH, TG의 수준을 감소시킨 것으로 보아 HM이 동맥경화 등 지질대사 이상에 의한 성인병에 효과가 있을 것으로 사료된다. MDA에서는 대조군에서 LPS가 간 염증을 유발하여 과산화지질함량이 증가한 것으로 사료되며 대조군에 비해 HM군이 과산화 지질함량이 감소된 것으로 보아 HM이 활성산소의 생성을 억제하여 높아진 간 조직 과산화지질함량을 감소시킴으로써 간기능 개선효과가 있을 것으로 사료된다.

The summary of a study of efficacy of Rose essential oil and Lavender essential oil against physiologic active change s of skin caused to surfactant is as follows. 1. In feed intake efficiency, there is more significant difference than control group, and then in water intake, there are significant differences between each group. It is presented that the water intake efficiency ratio of the group treated by Rose essential oil and Lavender essential oil is higher than all of groups to be participated in experiment. And then, the reason that the group treated Lavender essential oil is lower than any other group is needed water intake to be caused by stress. 2. As the result of serum analysis, in atherosclerotic index(A.I), the cholesterol of control group is higher than that of the group treated. As HDL cholesterol is activated, the dan1aged group is higher than control group, in LDL cholesterol the control group is higher. It is seen that the damaged group of the quantity of HDL cholesterol is lower frequently in A.I. This fact is presented that HDL cholesterol that cholesterol is exhausted is changed, because of the dan1aged group that replacement is activated. 3. As the observed result of alteration of sebaceous glands, it is appeared that the demage of sebaceous glands is destroyed in the damaged group. It is observed that epidermis of the group applied by Rose essential oil after treated surfactant is dry, secretion of phenomenon of water and sebum is appeared more. It is observed that the epidermis recovery of the group applied by Lavender essential oil after treated surfactant is insufficient. And then it is seen that stratum corneum is recovered and the quantity of sebum secretion is decreased. 4. As the observed result of alteration of Mast cell group treated by Rose essential oil and Lavender essential oil for 3 weeks Luna's stain(${\times}100$), it is observed that the damaged group treated by Lavender essential oil is numerous in alteration of mast cell's number and Mast cell's size is larger than the dan1aged group. It is presented that the Mast cell's number and Mast cell's size is larger than the damaged group, the Mast cell's size and quantity of the group treated by Rose essential oil and Lavender essential oil is decreased more.

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.

난포액에 함유되어 있는 steroids와 sterol이 수정에 참여하는 정자의 주화성에 미치는 영향을 밝히기 위하여, progesterone, estradiol 17 beta 및 cholesterol이 sucrose 층으로부터 정자의 swim-up 분리에 미치는 영향을 조사하였던 바 얻어진 결과는 다음과 같다. 1. Progesterone은 정자의 이동과 운동성을 억제하였으나 수정능획득한 정자를 유인하였으며, 특히 50$\mu$g/ml 수준의 progesterone은 수정능력을 획득한 정자의 이동을 유의하게 자극하였다. 2. Estradiol 17 beta의 첨가수준이 증가할수록 정자의 이동과 운동성이 억제되었으나, 10$\mu$g/ml 수준의 estradiol은 정자의 이동과 운동성 및 수정능획득정자의 이동에 영향을 미치지 않았다. 3. Cholesterol은 정자의 이동과 운동성을 자극하였으나, 수정능획득정자의 이동에 영향을 미치지 않았으며, 특히 50$\mu$g/ml 수준의 cholesterol은 정자의 이동과 운동성을 유의하게 자극하였다. 4. Progesterone, estradiol 및 cholesterol의 병용처리에서, cholesterol은 정자의 이동과 운동을 유의하게 자극하였으나, progesterone과 estradiol은 이러한 cholesterol의 효과를 감소시켰다. Progesterone은 수정획득 정자의 이동을 자극하였으나 estradiol이나 cholesterol은 progester-one의 이러한 효과를 억제하지 않았다. 결론적으로 progesterone은 50$\mu$g/ml 첨가수준에서 수정능력을 획득한 정자의 swim-up이동을 유의하게 자극하였으며, cholesterol은 50$\mu$g/m1 첨가수준에서 정자의 이동을 자극하였으나, estradiol은 10$\mu$g/m1 첨가수준에서 정자의 이동과 운동성에 영향을 미치지 않았다.

Fermented milk has been developed with its functionalities, and its health-promoting ability has been spotlighted due to its relationship with diseases such as cancer, cardiovascular disease, and diabetes, and gut microbiota. As national burden of cardiovascular disease increases over time, there is a need to prevent hypercholesterolemia. To achieve that, gut microbiota, which is altered by host's diet and environment, plays important roles in lowering cholesterol in the blood. Moreover, fermented milk may be effective as a cholesterol-lowering agent by altering gut microbiota composition. Gut microbiota may alter not only functions of the fermented milk but also bio-accessibility of functional materials. These results suggested that gut microbiota composition influences the impact of fermented milk. Thus, we should understand how functional materials are degraded by gut microbiota and absorbed into the gut.

This study examined the effects of dietary ${\beta}$-cyclodextrin (${\beta}CD$) on the cholesterol of blood and tissues of swine. Thirty six male castrated swine ($Landrace{\times}Yolkshire{\times}Duroc$) weighing 50 kg were randomly assigned to one of four dietary groups until their weight reached 110 kg. The groups were: basal diet without ${\beta}CD$ (control) and basal diets containing 1.5%, 3.0%, or 5.0% ${\beta}CD$. Diets and water were offered ad libitum. No significant difference was found between treatments in terms of feeding performance measured by daily intake, daily weight gain, and feed efficiency. Addition of ${\beta}CD$ to the diets significantly reduced total lipid, triglyceride and total cholesterol levels in swine blood, particularly in the group receiving 5.0% ${\beta}CD$, which showed decreases (p<0.05) of 21.9%, 55.6% and 27.7%, respectively. Cholesterol levels in back fat, loin, belly and ham portions of swine fed ${\beta}CD$ significantly differed (p<0.05) from controls, especially in the 5.0% ${\beta}CD$-fed group, with reductions of 26.0%, 27.5%, 17.9% and 18.3%, respectively. These results suggested that the addition of ${\beta}CD$ to the diet of swine could reduce their body cholesterol by decreasing the migration of cholesterol through the blood.
