The purpose of this study was designed to observe the effects of the feeding Cynanchum wilfordii extract on the improvement of the blood glucose, lipid components in the serum of dietary hyperlipidemic and streptozotocin(STZ) -induced diabetic rats(S.D. strain, ♂) fed the experimental diets for 5 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-Cholesterol, free-cholesterol. cholesteryl ester, TG, PL and blood glucose in serum were significantly higher in the cholesterol administration groups((group 2(cholesterol+water), 4(cholesterol+Cynanchum WIlfordii 3.5g% extract)) than those in the control group (group1 , basal diet+water). But the concentrations of total cholesterol. atherosclerotic index, LDL, LDL- cholesterol. free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum were remakably lower in the group 4 than those in the group 2. In the STZ(55mg/kg B.W.)-induced diabetic groups((group 3(STZ, IP.)+water), 5(STZ(IP.)+Cynanchum WIlfordii 3.5g% extract? the serum total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol. cholesteryl ester, TG, PL and blood glucose concentrations actions were rather lower in the group 5 than those in the group 3. In the ratio of HDL -cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Cynanchum wilfordii extract administration groups were higher percentage than III the groups 2 and 3. The activities of aspartate aminotransferase(AST), alanine aminotransferase(ALT), alkaline phosphatase (ALP) and lactate dehydrogenase(LDH) in serum were rather lower in the Cynanchum wllfordii extract administration groups (group 4,5) than in the cholesterol diet group(group 2) and STZ-induced diabetic group (group 3). From the above research, the physiological activity substances in Cynanchum wllfordii were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic and STZ-induced diabetic rats. And particularly, physiological activity substance in Cynanchum wilfordii was more effective therapeutic regimen for the control of metabolic derangements in adult disease.

The purpose of this study was to investigate the effect of dietary dae-chu(Rhamnace ziziphus, A), onion(Allium cepa L., O), mixture extracts (mulberry leaf, licorice root, pine needle, angelica gigas, jujube, onion, M) on serum glucose, lipid, enzyme, phosphorus levels in rats (Sprague-Dawley male rats, $357.03{\pm}7.08g$). Serum calcium of onion group was significantly decreased (p<0.05), but mixture extracts group of Cl (p<0.05) and TBIL (total bilirubin, p<0.05) were significantly increased. Serum glucose, total cholesterol, HDL-cholesterol and triglyceride were increased experimental rats than those of the normal rats. Mixture extracts was better than other groups for lipid metabolism. Also, GPT(glutamic pyruvic transaminase) and GOT(glutamic oxaloacetate transaminase) of onion extracts were protected to liver. So mixture and onion extracts were good drink for health.

The aims of this study are conducted to investigate the effect of pretreatment with Achatina fucica extract (AFE) in streptozotocin (STZ)-induced diabetic rats. Serum glucose, total lipid and triglyceride levels of administration group of AE in diabetic rats induced by STZ were significant high levels than that of control group. However, glucose, triglyceride and lipid levels were significant lower level in group of pretreatment with AFE and Atheroslerotic index decreased in the group of treatment of AFE when those levels compared with that of STZ-treated group. Serum lipase activity was inhibited in the control group STZ induced diabetic rats, in contrast lipase activity increased in the group of AFE administration. These results suggested that AFE may use to prevent the diabetes mellitus induced by STZ.

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.

This study was conducted to investigate the effects of dietary coconut oil as a medium-chain fatty acid (MCFA) source on performance, carcass composition and serum lipids in male broilers. A total of 540, one-day-old, male Arbor Acres broilers were randomly allotted to 1 of 5 treatments with each treatment being applied to 6 replicates of 18 chicks. The basal diet (i.e., R0) was based on corn and soybean meal and was supplemented with 1.5% soybean oil during the starter phase (d 0 to 21) and 3.0% soybean oil during the grower phase (d 22 to 42). Four experimental diets were formulated by replacing 25%, 50%, 75%, or 100% of the soybean oil with coconut oil (i.e., R25, R50, R75, and R100). Soybean oil and coconut oil were used as sources of long-chain fatty acid and MCFA, respectively. The feeding trial showed that dietary coconut oil had no effect on weight gain, feed intake or feed conversion. On d 42, serum levels of total cholesterol, low-density lipoprotein cholesterol, and low-density lipoprotein/high-density lipoprotein cholesterol were linearly decreased as the coconut oil level increased (p<0.01). Lipoprotein lipase, hepatic lipase, and total lipase activities were linearly increased as the coconut oil level increased (p<0.01). Abdominal fat weight/eviscerated weight (p = 0.05), intermuscular fat width (p<0.01) and subcutaneous fat thickness (p<0.01) showed a significant quadratic relationship, with the lowest value at R75. These results indicated that replacement of 75% of the soybean oil in diets with coconut oil is the optimum level to reduce fat deposition and favorably affect lipid profiles without impairing performance in broilers.

In Korea, the concerns about the consumption of soy-based infant formulas have received considerable public attention. In has been known that the n-3/n-6 ratio of soy has a beneficial effect on the health. This study was conducted to investigate whether the soy-based infant formula has an effect on the composition of fatty acids in erythrocytes with regard to the plasma lipid levels in full-term infants. The infants who were delivered at Kyung Hee Medical Center were recruited. Experimental groups were the breast milk group(n=17), soy-based infant formula group(n=12) and casein-based infant formula group(n=19). Anthrophometic and dietary assessments were performed and the composition of RBC fatty acids and blood lipid levels were measured. The body weight, length, chest circumference and head circumference of the subjects were normal growth range showing no significant difference among the experimental groups. The ratio of n-3/n-6 ratio in breast milk, soy-based infant formula and casein-based infant formula were 0.11, 0.14 and 0.13, respectively. N-3/n-6 ratio of the subjects erythrocyte fatty acids for each groups were 0.18, 0.21 and 0.17, respectively. Most of the fatty acids of erythrocyte were not significantly different among the three experimental groups. The blood lipid levels of each experimental group were normal range. The total lipid level of casein-based formula group was higher than that of other experimental groups and LDL-cholesterol level of soy-based formula group was the lowest among the three groups.

Objectives : This study was performed to investigate the effects of Rhizoma Arisaematis water extract on lipid and glucose metabolism and histochemical change of obese rats. Methods and materials : 10 rats were divided into normal, control and RA (Rhizoma Arisaematis) groups. We fed the control group a high-fat diet and administered normal saline for 8 weeks. We fed the experimental group of rats a high-fat diet and administered an extract of Rhizoma Arisaematis for 8 weeks. At the end of the experiment, the rats were sacrificed to determine their chemical composition. The groups were examined for effects on blood serum lipids, blood sugar, blood insulin concentration and epididymal fat cells. Results : 1. Serum total cholesterol, triglyceride, HDL-cholesterol and glucose of the RA group decreased compared with those of the control group. These decreased rates were significant(P<0.05). 2. Serum LDL-cholesterol, total lipid, free fatty acid and the average size of epididymal fat cells of the RA group decreased compared with those of the control group. These decreased rates were significant(p<0.01). Conclusions : These results suggest that RA may be used to prevent or cure the obesity iniduced by a high-fat diet.
