The effects of taurine on plasma and liver cholesterol, erythrocyte ouabain sensitive Na efflux and platelet aggregation were examined in Sprague Dawley rats fed control or 0.5% cholesterol with 0.2% cholate diet. Plasma and liver levels of total cholesterol were increased significantly (p<0.05) in rats fed cholesterol diet compared to the control, and taurine significantly decreased the elevated plasma level of cholesterol in rats fed cholesterol diet (p<0.05). HDL-cholesterol was decreased in groups fed the cholesterol diet regardless of taurine supplementation and the difference between groups with and without cholesterol was significant (p<0.01). Plasma triglyceride was decreased and liver triglyceride was increased both significantly (p<0.05) in rats fed cholesterol compared to the control. Plasma and liver triglyceride in rats fed taurine was decreased significantly compared to the control (p<0.05). Intracellular Na tended to be lower in rats fed cholesterol or taurine and higher in rats fed cholesterol plus taurine compared to the control. Na efflux through Na-K ATPase and the passive leak of Na was somewhat reduced in rats fed cholesterol or taurine and was augmented in rats fed cholesterol plus taurine compared to the control, which showed a similar trend to the intracellular Na. Taurine supplementation caused a suppression of Na efflux in groups fed control diet and restored the suppressed Na efflux in groups fed cholesterol. Platelet aggregation was significantly decreased in the group fed taurine compared to the control (p<0.05) and the group fed cholesterol plus taurine was also a little lower in aggregation than the group fed cholesterol. Microscopic examination showed that taurine prevented fatty liver in rats fed cholesterol diet. Taurine known for stimulating Na-K ATPase in some cell types rather decreased erythrocyte ouabain sensitive Na-K ATPase in the present study. Taurine had hypolipidemic and hypocholesterolemic effects and inhibited platelet aggregation which may be favorable for prevention of cardiovascular diseases.

Purpose : The purpose of this study was to analyze the correlations among bone mineral density(BMD), serum lipid levels, and cognitive function in the elderly with dementia. Methods : We recruited seventy elderly with dementia(men=35, women=35) to participate in the Korean mini mental state examination(K-MMSE). Their T-scores and serum lipid levels were analyzed for correlation analysis. Results : The results of this study showed that there are significant correlations between cognitive function and three factors BMD, low-density lipoprotein cholesterol(LDL-C) level, and total cholesterol(TC) level. The cognitive function scores increased proportionally with BMD but were inversely proportional to LDL-C and TC levels. There were no significant relations among cognitive function, high-density lipoprotein cholesterol(HDL-C) level, and triglyceride(TG) level. Conclusion : These results indicate that there is a direct proportionality between cognitive function and BMD and inverse proportionalities between cognitive function and LDL-C level and between cognitive function and TC level. Therefore, these levels can be indices for preventing and predicting dementia.
The present study was carried out to investigate the effects of magnesium supplement levels and periods on lipid metabolism in male Sprague-Dawley rats given low protein and magnesium deficient diets. The effect of magnesium supplement levels and periods on lipid metabolism in rats given a low protein and magnesium deficient diet for 2 weeks were investigated. Serum total lipid and triglyceride contents were significantly lower in magnesium supplement group compared with magnesium deficient group. Serum HDL-cholesterol/total cholesterol ratio was significantly increased as magnesium supplement level was increased. Liver total lipid, triglyceride, total cholesterol and phospholipid contents were significantly lower in magnesium supplement group than those in magnesium deficient group. Serum ALP, GOT and GPT activities were significantly decreased in magnesium supplement group compared with magnesium deficient group. In summary, the effect of magnesium supplement on lipid metabolism and enzyme activities were significant and we can see that magnesium supplement level propered to be requirement level(400 mg/kg diet)in the other cases except serum lipid contents.
A meta-analysis of 63 randomized controlled trials of Pioglitazone and Rosiglitazone in patients with type 2 diabetes was conducted. Pioglitazone significantly lowered fasting plasma glucose and triglyceride (TG) level and increased high-density lipoprotein cholesterol (HDL) level. Rosiglitazone significantly lowered hemoglobin A1C level and fasting plasma glucose, whereas it increased all kinds of lipids (HDL, LDL (low-density lipoprotein cholesterol), TG, total cholesterol). In comparison, glucose lowering effect was higher in Rosiglitazone, and Pioglitazone produced a more favorable lipid profile.
Background: Pleural effusion is one of the most common clinical problems in pulmonology because of high prevalence of pulmonary tuberculosis and bronchogenic carcinoma in Korea. The differential diagnosis between pleural transudate and exudate is very important, but it is very difficult in some cases. Methods: In order to assess the clinical usefulness of cholesterol levels for the differential diagnosis of pleural transudate and exudate, we measured pleural fluid cholesterol levels by enzymatic method in 45 patients who were admitted due to pleural effusion. Results: The mean cholesterol level of transudate was $33.1{\pm}12.9\;mg%$, tuberculous exudate was $97.3{\pm}28.2\;mg%$ and malignant exudate was $97.3{\pm}28.2mg%$. When the cut-off value of pleural cholesterol level was 60 mg%, one case (6.7%) of tuberculous exudate and two cases (13.3%) of malignant exudate were incorrectly classified, but all cases of transudate were classified correctly. When the cut-off value of pleural/serum cholesterol ratio was 0.3, one case (6.7%) of transudate and two cases (13.3%) of malignant exudate were incorrectly classified, but all cases of tuberculous exudate were classified correctly. When the cut-off value of pleural cholesterol level to differentiate pleural transudate from exudate was 60 mg%, sensitivity was 90% and specificity was 100%. When the cut-off value of pleural/serum cholesterol level to differentiate pleural transudate form exuidate was 0.3, sensitivity was 93% and specifiity was 93%. Conclusions: From the above results, it can be concluded that measurement of pleural fluid cholesterol levels is useful for the differential diagnosis between pleural transudate and exudate.
An experiment was conducted to determine the effects of supernormal level of copper (Cu) from different supplementary sources on the performance, cholesterol level in plasma and breast muscle, and accumulation of fat and Cu in broilers. In a 5 wk feeding trial, two hundred forty hatched male broiler chickens were assigned to four dietary treatments: control diet containing 10 mg/kg supplementary Cu, control diet plus 250 mg/kg Cu from $CuSO_4$ ($CuSO_4-250$), control diet plus 125 mg/kg Cu from Cu-methionine chelate (Cu-Met-125), and control diet plus 250 mg/kg Cu from Cu-methionine chelate (Cu-Met-250). Weight gain in Cu-Met-125 treatment and Cu-Met-250 treatment were not different, but they were significantly (p<0.05) greater than that in $CuSO_4-250$ treatment. Plasma total cholesterol and reduced glutathione (GSH) in blood were significantly reduced by supplementation of $CuSO_4-250$, but were not significantly affected by Cu-Met supplementations. Plasma HDL cholesterol, plasma triglycerides and breast muscle cholesterol were not significantly affected by Cu supplementation. $CuSO_4-250$ improved metabolizability of crude fat, which resulted in low abdominal fat pad weight. Cu from Cu-Met was better absorbed and accumulated more in the breast muscle and lesser in the liver compared with Cu from $CuSO_4$.
The purpose of this study was to evaluate the effect of Self-foot Reflex Massage (SRM) programme on the physical condition and anxiety level of hypertension workers. The research was designed in the pre and post-test. Sample test was done in five workers with essential hypertension. They were divided in two groups:- Group A and Group B. The Self-foot Reflex Massage (SRM) was applied three times a week for Group A and five times a week for Group B. The SRM was given in 40 minutes each time for 4 weeks from the 1st of January to the 30th of April in 2001. In order to evaluate the effect on SRM. blood pressure, total cholesterol, triglyceride, HDL cholesterol and LDL cholesterol were measured as physical parameters and state trait anxiety inventory was used twice each time between before and after the exercise. The collected data was analysed by Mann-Whitney test with SPSS program. The results were as follows: 1. Average age for the subjects were 39.8 (ranged from thirty-two to fifty-three) and average period of hypertension history was 42 months (ranged from twenty to eighty-four). 2. There was no significant difference between two examined groups in blood pressure. But, there was a significant difference in SRM of pre and post-test for two groups. 3. There was no significant difference in blood cholesterol between two groups and between pre and post-test. 4. State trait anxiety showed significant difference between pre and post-test except the results between two groups. This result suggests that SRM is effective on the decrease of systolic and diastolic pressure and the relief of state trait anxiety except for the blood cholesterol. Therefore, blood cholesterol is needed further evaluation in large subjects and longer period. Further research is regarded as necessary to evaluate and to compare the precise effects of SRM on the foot reflex massage (FRM) in anxiety.

Objective : Previous studies reported a correlation between the low serum cholesterol level and impulsive behaviors. In this study, we investigate an association between the serum lipid levels and psychological parameters in maladaptive soldiers in the Korean Army. Methods : A total of ninety-six maladaptive subjects and thirty-six normal controls in the Korean army were evaluated with the Korean version of Barratt Impulsiveness Scale (K-BIS), Korean version of Beck Suicidal Ideation Scale (K- BSIS), Korean version of Beck Depression Inventory (K-BDI) and Korean version of Beck Anxiety Inventory (K-BAI). Serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL) and high density lipoprotein (HDL) level were measured by overnight fasting blood sampling. Results : There were no significant differences between the groups in demographic characteristics. Serum total cholesterol levels (t=-2.209, p=0.032), triglyceride levels (t=-4.593, p<0.001), and LDL levels (t=-3.753, p=0.001) of maladaptive subjects were significantly lower than those of normal controls, and maladaptive subjects had higher K-BIS scores than normal controls (t=7.542, p<0.001). Negative correlation was found between LDL levels and non-planning impulsiveness in the maladaptive subjects (r=-0.253, p=0.013). LDL levels (${\beta}=-0.258$, p=0.008) and K-BDI scores (${\beta}=0.266$, p=0.043) emerged as significant predictors for non-planning impulsiveness. Conclusion : These results suggested that LDL level was associated with non-planning impulsiveness. These findings suggested that serum cholesterol levels might be available as a biological marker of impulsiveness. However, more large samples, longitudinal biological study and psychiatric evaluations should be needed to develop a preventive intervention for maladaptive male conscripts in the Korean army.

This study was conducted to investigate the effect of water-soluble extract from roasted chicory on the lipid metabolism and oxidative stress in male Sprague-Dawley rats. The experimental groups were divided into three groups ; the normal group, the cholesterol group and the chicory group. Roasted chicory extract was supplemented at 5.0% (w/w) level in the cholesterol diet. Concentration of total cholesterol in serum was significantly higher in the cholesterol group than in the normal group, but this increase in the cholesterol group was significantly decreased by the cholesterol diet supplemented with chicory extract. Concentration of HDL-cholesterol in serum was significantly lower in the cholesterol group than in the normal group, but this decrease in the cholesterol group tended to increase in the chicory group. However, concentrations of triglyceride, phospholipid and nonesterified fatty acid in serum were not significantly different among the groups. Concentrations of triglyceride and cholesterol in liver were significantly higher in the cholesterol and chicory groups than in the normal group. Feces weight and the excretion of cholesterol and bile acid into feces were significantly higher in the chicory group than in other groups. Concentrations of thiobarbituric acid reactive substances (TBARS) in homogenates and microsomal fractions of liver were not significantly different among the groups. On the other hand, concentration of 8-hydroxydeoxyguanosine (8-OHdG) as an useful marker of oxidative stress in urine was lower in the chicory group than in other groups. Concentration of serum glucose was signnificantly lower in the cholesterol group than in the normal group, but that of the chicory group was significantly higher than in the normal group. These results demonstrated that dietary chicory extract exerted the decreasing effect of cholesterol level and oxidative stress in cholesteral-fed rats.
Opuntia ficus-indica is widely used as folk medicine for burned wound, edema and indigestion, etc. After the adaptation of rats for seven days, OF (200mg/kg) was administered into rats intraperitoneally every day for two weeks. On the 14th day, $3.3m\ell$ of $CCl_4$ (50% $CCl_4$ : Olive oil = 1 : 1) was treated to rats and on the 15th day, they were operated. We measured the levels of total cholesterol, HDL-cholesterol, LDL-cholesterol, total lipid and triglyceride (TG) in serum and Malondialdehyde (MDA) in liver tissue. Opuntia ficus-indica and $CCl_4$-treated group (OFC) significantly decreased lipid peroxidation by 32.6% compared to $CCl_4$-treated abnomal group (CTA). Total lipid and TC of OFC administered group were lower than those of CTA group. Cholesterol levels showed significant effect in OFC group. Total cholesterol and LDL-cholesterol in OFC administered group were decreased by 12.7% and 17.4%, respectively, compared to those of CTA group. HDL-cholesterol in OFC administration group was increased by 19.7% compared to CTA group. This finding suggests that lipid peroxidation was inhibited in the significant level when $CCl_4$-induced rats were treated with OF. Based on this analysis, further study to identify the active components in this sample is warranted.
