This study was conducted for a period for 5 weeks in order to evaluate effects of brewer's yeast slurry(BYS) on the growth performance, organ development and blood composition of broiler chicks. A total number of 84 one day old broiler chicks were allocated to one of three supplemented diets: 0%(control), 2% and 4% BYS. Body weight gain and feed efficiency of chicks fed the diet supplemented with 4% BYS significantly was increased by 9% and 8%, respectively, compared to the control diet(P<0.05). The BYS supplements did not affect weights of liver, heart and abdominal fat, and their ratios per body weight. However, in 4% BYS supplement group, ratio of liver to body weight significantly decreased(P<0.05) by 12%, compared to the control. The supplement of 4% BYS decreased the concentration of triglyceride by 31%, and increased the concentration of high density lipoprotein(HDL) by 26%, compared to the control(P<0.05). These results indicated that the supplementation of 4% BYS in diet can improve body weight gain as well as feed efficiency, and increased the concentration of blood HDL, and ratio of HDL to total-cholesterol of broiler chicks.
Dongchunghacho rice, produced by cultivating Dongchunghacho fungus on rice, could be an effective functional food because it offers added value to rice and thus increases rice consumption. However, the physiological effect of Dongchunghacho rice has not been reported yet although there is increasing consumers demand. Therefore, we investigated the effect of Dongchunghacho rice (unpolished rice cultivated with Cordyceps militaris) on lipid metabolism in hyperlipidemic rats. Forty of 8 wk-old male Sprague-Dawley rats were divided into four groups after a 1 week of adaptation period and fed either a normal diet (66% polished rice diet, NC), high fat (12 g/100 g)-high cholesterol (1 g/100 g) diet with 53% polished rice (HC), or high fat-high cholesterol diets supplemented with 30% of the total rice as either unpolished rice (DR) or Dongchunghacho rice (DR). After 4 weeks, rats fed the Dongchunghacho rice diet with high fat and cholesterol had dramatically lower plasma LDL cholesterol concentrations and atherogenic indexes and higher plasma HDL cholesterol levels compared with the rats consuming polished rice or unpolished rice with high fat and cholesterol diet. Dongchunghacho rice led to less total lipid and total cholesterol accumulation in liver. However, these significant reductions in plasma or hepatic lipid profiles were not closely correlated with fecal total lipid or total cholesterol excretion. The plasma concentration of total cholesterol and triglycerides were not affected by Dongchunghacho rice. This hypolipidemic effect of Dongchunghacho rice seemed to be unrelated to unpolished rice itself, because the plasma and hepatic lipid profiles of DR group were not different from that of the HC group. These results suggest that unpolished rice containing cultivated Cordyceps militaris can improve plasma and hepatic lipid profiles in rats fed with high fat-high cholesterol diet.

In present study possible hypolipidemic effects of garlic were investigated in an experimental model which consisted of 4 groups of Wistar rats(three weeks old): CO group received a basal diet(as a standard diet) contained 6.3% of corn oil. LO group was taken the experimental diet in which only 6.3% corn oil in basal diet was substituted by 12.6% of lard oil. So the experimental diet was somewhat high saturated fat diet. LG1 group was treated orally with garlic juice as 1% of raw garlic in the diet together with the same diet as the diet for LO group. LG2 group was taken 2% of garlic under the same dietary condition as that of LG1 group. The rat body weights prior and posterior to the experimental period were measured and the amount of the experimental dietary intake was determined at every 3 day interval. After the experimental dietary period of 30 days the blood obtained from all the sacrificed rats were analyzed for the biochemical parameters. Over the one month period of experiment there was no abnormality or apparent change in appearance and activity or diet consumption in all experimental rat groups. LO group fed a diet rich in lard showed significantly increased body weight gain rate by 30% and also elevated levels of triglyceride, total cholesterol and LDL cholesterol by 29.9%, 27.4% and 62.3% respectively and no significant difference in the levels of HDL cholesterol, GOT, GPT, blood glucose and blood urea nitrogen as compared to those of control group. So it seemed that the high calorie diet in LO group mainly contributed to the significant increase in body weight gain rate and other biochemical parameters. In spite of 1% garlic treatment LG1 group had significantly increased body weight gain rate by 25.2%, levels of triglyceride, total choesterol and LDL cholesterol by 25.2%, 24.6% and 50.5% respectively as compared to control and LO group, and no increase in the levels of HDL cholesterol, blood glucose and blood urea nitrogen. At garlic 1% diet there was no hypolipidemic efficacy in rat serum. Under the treatment with garlic 2% in diet LG2 group showed significantly increased body weight gain rate by 19.7% as compared to control and elevated levels of GOT, GPT and BUN by 85.8~96.4%, 127~148% and 88% respectively as compared to control, but LG2 group had significantly reduced levels of triglyceride, total cholesterol and LDL cholesterol as compared to LOand LG1 group. In present study there were no significant change in HDL cholesterol and blood glucose value. In LG2 group GOT, GPT and blood urea nitrogen values were slightly increased presumably due to the inhibiting effects of garlic on the hepatic or renal function of rats. Nevertheless in this study garlic may have some demonstrable hypolipidemic effects in rat.
This study was conducted to investigate the effects of dietary supplementation of garlic by-products on performance, proximate composition, carcass characteristic, cholesterol, and blood composition of chickens. Broiler chicks were fed diets for 5 weeks with a diet 1% garlic by-product (T1), 2% garlic by-product (T2), and 5% garlic by-product (T3). There were no difference among diet in performance. In proximate composition, crude fat of chicken meat was decreased in diets by addition of garlic by-product than control, but moisture and crude ash were no significant difference. Liver weight was significantly increased (P<0.05) by the dietary supplementation with garlic by-products compared to the control diet. The total cholesterol and LDL-cholesterol of treatment groups was lower than control, and the HDL-cholesterol of treatment groups was higher than control (P<0.05). Especially, T3 was significantly (P<0.05) more effective in improving cholesterol compared to other treatment groups. In blood composition, GOT of broiler was decreased in diet by garlic by-products than control group, but GPT, triglyceride, and glucose were no significantly different. In conclusion, these data indicate that supplementation of garlic by-products (T3) were most effective in decreasing total cholesterol, LDL-cholesterol, and GOT and increasing HDL-cholesterol.
This study was conducted to determine the association between dietary calcium intake and biomarkers related to lipid and glucose metabolism and inflammation in Korean patients with type 2 diabetes. Seventy-five subjects (41 males, 34 females) were recruited from a group of patients who had visited the department of endocrine medicine. Data on anthropometric characteristics, clinical indices such as hemoglobin A1c and C-reactive protein (CRP), and dietary nutrient intakes were collected. Subjects were divided into three groups on the basis of their calcium intake [< EAR (below estimated average requirement), EAR-RNI (between EAR and recommended nutrient intake), > RNI (above RNI)]. Average calcium intake of < EAR, EAR-RNI, > RNI groups were $462.7{\pm}18.7$, $649.7{\pm}12.8$, and $895.7{\pm}21.7mg$, respectively. Energy intake was not different among groups but intakes of protein, total and saturated fatty acids were significantly higher in > RNI group than < EAR group. Analysis of covariance revealed that HDL cholesterol level was significantly higher in EAR-RNI group, as compared to < EAR group after adjustment with confounders such as age, sex, BMI and energy intake (p < 0.05). Levels of CRP and homeostasis model assessment 2-insulin resistance (HOMA2-IR) were significantly lower in EAR-RNI group. Total cholesterol level was higher in EAR-RNI and > RNI groups, although within the normal range. Our results suggest that dietary calcium intake may influence the levels of HDL-cholesterol, CRP and HOMA2-IR and subsequently, help management/treatment of type 2 diabetes patients.
Effects of fermented milk were tested in Sprague-Dawley male rats. In six treatment 150 rats were fed for 12 months: (1) normal control synthetic pellets+water, (2) cholesterol control synthetic pellets containing 1% of cholesterol and 500, 000 IU of vitamin D2/100 g (cholesterol pellets) +water, (3) cholesterol pellets+25% fermented milk, (4) cholesterol pellets+50% fermented milk, (5) cholesterol pellets+75% fermented milk, (6) cholesterol pellets+100% fermented milk. In 3, 6, 9, 12 months, rats were sacrificed for analysis of samples. Rats received the fermented milk had significantly lower (p<0.05) serum cholesterol levels and higher ratios of HDL-cholesterol to total cholesterol than did the water fed rats. Stomach, heart, abdominal aorta and kidney of rat from fermented milk group showed slighter calcification or necrosis than did those of rat from cholesterol control group. Weight gain, diet intake, and drink consumption were significantly different among groups. Results indicate that fermented milk had a helpful effect of experimental hypercholesteremia and atherosclerosis.
This study was carried out in 14,443 subjects(8,706 men, 5,737 women, mean age $41.8{\pm}9.16$) who visited the health promotion center of one university hospital. Serum $T_3$, $T_4$ and TSH concentrations were measured with CIA using commercial kits on ADVIA Centaur Assay and Serum total cholesterol, triglyceride, and HDL-cholesterol were measured by auto-analyzer Hitach 7600 in enzyme method. 1. The prevalence of subclinical hypothyroidism was 12.6/1,000 population(men 6.0/1,000, women 22.7/1,000) and as high as about 4 times in women than in men. 2. In subclinical hypothyroidism, the values of total cholesterol and LDL-cholesterol were significantly high by 5.5 mg/dL, 4.6 mg/dL compared with normal group(p<0.05). 3. In all the tested hypercholesterolemia and hyperLDL-cholesterolemia, were correlated with TSH. There is higher correlation in women group than men group. These results indicate that the subclinical hypothyroidism and dyslipemia significantly correlated. Especially, it is very important to find that the hypercholesterolemia and hyperLDL-cholesterolemia are the high risk factors of atherosclerosis. Therefore, it is essential for the group of subclinical hypothyroidism to take the cholesterol, LDL-cholesterol and serum lipid test as well as thyroid function test.

PURPOSE: The purpose of present study was to investigate effects of obesity, blood pressure and life style on lipid indices and blood pressure in men of age 40s. METHODS: One hundred forty five subjects in men of age 40s were participated in this study. All participants were taken physical examination, lifestyle survey and laboratory test. According to examination, participants were divided into two group in four categories ; obesity and normal group, hypertension and normal group, smokers and non-smokers, and drinkers and non-drinkers. The low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL), total cholesterol (TC), triglyceride (TG), systolic blood pressure (SBP), diastolic blood pressure (DBP) were analyzed by independent t-test for comparison between two groups. RESULTS: The values of LDL, TC, SBP, DBP were higher and HDL was lower in obesity than in normal group (p<.05). The values of LDL, TC, SBP, DBP were higher in hypertension group than in normal group (p<.05). The values of TG was higher and HDL was lower in smokers than in non-smokers (p<.05). There's no significant differences between drinkers and non-drinkers (p>.05). CONCLUSION: It can be seen that obesity and blood pressure were more relative risk factors than smoking and alcohol indices in cardiovascular diseases.
This study was designed to determine changes of serum glucose and lipid levels in noninsulin dependent diabetes mellitus patients during different doses of docosahexaenoic acid (DHA)-rich fish oil supplementation. All patients had a fasting blood glucose of less than 180mg/dl, a LDL-cholesterol of less than 160mg/dl, and a triglyceride of more than 160mg/dl. None had clinical evidence of renal, hepatic or coronary vascular disease. Sixteen patients served as control. Seven patients ingested 2.00g of fish oil(low dose group), consisting of 0.30g eicosapentaenoic acid(EPA) and 0.55g DHA. The group of modest dose(n=9) was provided 3.91g of fish oil, consisting 0.59g EPA and 1.08g DHA. After 4 weeks, serum triglyceride concentration showed a mild but nonsignificant elevation in control group, a 9% decrease(194 to 177mg/dl) in the group of low dose of fish oil and a 28% decrease(206 to 161mg/dl) in the group of modest dose. The level of high density lipoprotein(HDL), HDL2, HDL3 and total cholesterol in all groups were not changed. There was a mild increase in malondialdehyde and low density lipoprotein(LDL)-cholesterol concentration and decrease in $\alpha$-tocopherol concentration. However, these changes were not significant.

The purpose of this study was to observe the effects of Cynanchi wilfordii Radix extracts (CRE) on the improvement of the lipid compositions and blood pressure level in spontaneously hypertensive rats (SHR) fed an experimental diet for 5 weeks. The rats were divided into 3 groups: a control group, a 0.5% CRE treated group, and a 1% CRE treated group. Consumption of CRE extract for 5 weeks in SHR significantly suppressed blood pressure rise with aging (p<0.05). After eating the experimental diets, the triglycerides in serum was significantly lower in the CRE group than that in the control group. The fasting glucose levels of the 0.5% and 1% CRE group had a tendency to be lower compared with those of the control group. Total cholesterol, HDL-cholesterol and HTR (HDL-cholesterol/total cholesterol) of the SHR in the 0.5% and 1% CRE diet were significantly increased compared to the control diet. Thus, long term consumption of CRE might be beneficial in lowering high blood pressure and the improvement of lipid metabolism in SHR rats.
