Natto is a Japanese traditional food made from whole soybeans by the fermentation of Bacillus natto. The purpose of this study was to investigate the effect of Natto mucilage on lipid metabolism in rats. The levels of total cholesterol, LDL-cholesterol and triglyceride in serum of rats fed Natto mucilage diets were lower than those in control rats, but serum HDL-cholesterol and phospholipid were higher than those in control rats. The results indicate that Natto mucilage may have more beneficial roles in lipid metablism because it decreased serum cholesterol and increased bilirubin excretion.

This study was carried out to investigate the effect of body weight reduction of noddle contained glucomannan in high fat diets-induced obese rats. Male Spraque-Dawley rats were randomly assigned to control and high fat diets groups for 4 weeks. Four weeks later, the control and high fat diet grpups were rearranged into 4 groups by different levels of nuddle containing glucomannan. After 5 weeks of feeding, serum and whole blood was analyzed. Obesity index was significantly lower in the group fed nuddle contained glucomannan than that of high fat diet groups. The status of white blood cells in hematological examination was significantly higher in rats fed high fat diet and was not significantly different by fed nuddle. Serum albumin levels were not significantly different although glucose levels in serum was significantly different among groups. Serum triglyceride and Total cholesterol levels were the highest levels in rats fed high fat diets and showed the lowest levels in rats fed nuddle.

The effects of Okcheonsan powder on the body weights, the organ weights, the blood glucose level, the lipid and protein concentrations of serum and liver in diabetic rats were studied. Female rats (Sprague-Dawley, mean weight 313.6$\pm$18.5 g) were randomly assigned to one normal and two diabetic groups. They were fed experimental diets for 5 weeks. The diabetic groups were divided into the diabetic control (D-control group) and 3% Ok-cheonsan groups (D-Okcheonsan group). Rats were injected with streptozotocin intraperitoneally to induce diabetes. The body weights, the concentrations of total lipid and triglyceride of liver, the concentrations of total protein and albumin of serum in tole D-control and the D-Okcheonsan groups were significantly decreased compared with those in the normal group. The pancreatic weight in the D-control group was significantly more increased than that in the D-Okcheonsan group, but in the D-Okcheonsan group it was similar to that in the normal group. The fasting blood glucose levels and the atherogenic index in all the diabetic groups were significantly higher than those in the normal group. The concentrations of triglyceride, total cholesterol and LDL-cholesterol of serum, and the cholesterol of fiver in the D-Okcheonsan group were significantly lower than those in the D-control group. The concentration of HDL-cholesterol and HDL-cholestrol/total cholesterol ratio of serum were similar to those in all the groups. The concentrations of phospholipid of serum and liver in the D-Okcheonsan group were significantly decreased compared with those of the normal group, In conclusion, the Okcheonsan powder feeding could decrease the pancreatic weight, the concentrations of the triglyceride, the total cholesterol and LDL-cholesterol of serum, and the cholesterol of liver in the diabetic rats. But the concentrations of the blood glucose, the hepatic triglyceride and the atherogenic index seems to be not affected by it.

In this study, we investigated the effects of ostrich extract combined with Korean herb medicine(OEKHM) on the serum parameters in carageenan induced paw edema in rats. Carageenan causes enhanced edema formation which contributes to the pathophysiology of inflammation. Male Sprague-Dawley rats were used. There were four groups of treatments: OEKHMs and the control. After treatment with oral doses of 3 mL/180 g BW. 3 kinds of OEKHMs were processed which were ostrich bone with flesh meat with herb medicine(BFH), ostrich bone with flesh meat(BF), and ostrich bone with internal organs(BI). The contents of crude fat of the BFH was lower, but crude protein and crude ash of the BFH were significantly higher than those of the BF and the BI. In case of the levels of minerals(Ca, P, Mg, Fe, Cu and Zn ) of the BFH were significantly higher than those of BF and BI. And the heavy metals(Pb and Cd) were not detected in the OEKHM. The serum level of triglyceride in the BFH treated group decreased compared to that of the edema induced group. The serum levels of HDL-cholesterol concentration in the BFH supplemented group increased compared to that of the other groups. The serum levels of minerals(Ca, Mg, Fe, Cu and Zn) of the BFH treated group significantly increased than those of other groups(p<0.05).

This study was performed to investigate the effect of ethanol extract of Pimpinella brachycarpa (PB) on serum and liver lipid metabolism in rats. Male Sprague Dawley rats were administered 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia. PB ethanol extract (200 mg/kg/day or 400 mg/kg/day) was also administered orally to rats with high cholesterol diet for 6 weeks. We divided 40 rats into five groups; normal diet group (NC), high cholesterol diet group (HC), normal diet and PB ethanol extract (200 mg/kg) administered group (NC-PB), high cholesterol diet and PB ethanol extract (200 mg/kg) administered group (HC-PBL), and high cholesterol diet and PB ethanol extract (400 mg/kg) administered group (HC-PBH). The growth rate and liver weight of the high cholesterol diet group was higher than those of the normal diet group, whereas those of the groups administered PB ethanol extract were gradually decreased. There was a signigicant increase in the activities of serum alanine aminotransferase (ALT), asparate aminotransferase (AST) and alkaline phosphatase (ALP) in the high cholesterol diet group. The administration of PB ethanol extract decreased serum ALT, AST and ALP activities in a dose-dependent manners. The high cholesterol diet group showed increased serum triglyceride, total cholesterol, free cholesterol and LDL-cholesterol levels, and decreased atherogenic index, HDL-cholesterol and phospholipid levels as compared with the normal diet group. PB ethanol extract administrated groups showed increased HDL-C/T-C, HDL-cholesterol and phospholipid levels, and decreased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels as compared with the high cholesterol diet group. There were no differences in the concentrations of serum triglyceride, phopholipid, LDL-cholesterol, HDL-cholesterol and free cholesterol between normal diet groups. The hepatic concentrations of total cholesterol and triglyceride were also lower in PB ethanol extract administrated groups than in the high cholesterol diet group. These results suggest that ethanol extract of PB exerts hypocholesterolemic effect by reducing serum and liver cholesterol contents.

Objectives : This study was performed to investigate the effect of root extract of Pueraria thunbergiana Bentham (Puerariae Radix, PR) in diabetic mice as similar as emaciation-thirst disease in Oriental medicine. Methods : C57BL/6 mice were fed high fat (HF) and high sucrose (HS) for 8 weeks, and then administrated with 90 mg/kg body weight (bw) of streptozotocin (STZ) for induction of diabetes which is similar to the middle emaciation stage. After 5 days, blood glucose levels were measured, and selected the mice with ranges above $250mg/d{\ell}$. PR water extract was administrated orally once a day for 4 weeks with high fat and high sucrose. The levels of glucose, insulin, total cholesterol, triglyceride, ${\gamma}glutamyl$ transpeptidase (${\gamma}GTP$), glutamic oxaloacetic transaminase (GOT) and glutamate pyruvate transaminase (GPT) were analysed in the serum. Also, observed their histological changes by hematoxylin and eosin (H&E) of different organs, lung, heart, pancreas, stomach, liver, and kidney. Results : PR extract significantly decreased the levels of serum glucose and insulin in diabetic mice. PR extract significantly increased the levels of triglyceride, total cholesterol, GOT and GPT in diabetic mice. In H&E stain, PR extract inhibited the histopathological changes of lung (as a channel of the upper emaciation stage in the channel-tropism theory), pancreas (as a channel of the middle emaciation stage) and kidney (as a channel of the lower emaciation stage) in diabetic damage. Conclusions : PR extract has an anti-diabetic effect in HF/HS and low-dose STZ-induced diabetic mice. This result suggests that PR follows the channel-tropism theory in the emaciation-thirst disease through the protection of lung, pancreas and kidney.

The effects of mycelium of Cordyceps militaris on the growth, the lipid metabolism, the serum protein levels and the enzyme activities in male rats were studied. Sprague-Dawley rats were given four different types of diets for a succeeding period of five weeks: either a control diet, a control diet supplemented with 2%, 3% or 4% mycelium of Cordyceps militaris (CM) powder. The body weight gain, hepatic weight, feed efficiency ratio and the feed intake of the rats given diets with 2%, 3% or 4% CM were similar to those in rats given the control diet. The concentrations of hepatic total lipid and triglyceride of rats fed the 3% or 4% CM diets were significantly lower than those of rats fed the control diet. But the concentrations of hepatic total cholesterol and phospholipid of rats fed the all CM diets were similar to those of rats fed the control diet. The concentrations of total lipid, total cholesterol, triglyceride phospholipid, and the atherogenic index, and the activities of glutamic oxaloacetic transaminase and lactic dehydrogenase in serum of rats fed the all CM diets were significantly lower than those of rats fed the control diet. No differences were noted in the concentrations of HDL-cholesterol, LDL-cholesterol, total protein, albumin and creatinine, and the activities of glutamic pyruvic transaminase, ${\gamma}$ -glutamyltranspeptidase and alkaline phosphatase in the serum among the rats with on all the experimental diets. These results showed that the all CM diets feeding decreased the total cholesterol, the triglyceride, the phopholipid, and the atherogenic index in serum of rats.

This study investigated the effects of Punica granatum L. (PG) ethanol extracts on serum lipid levels in ovariectomized rats. In order to elucidate the effects of PG ethanol extracts on the change of lipid concentration in rats, Sprague-Dawley female rats were randomly assigned to groups as follows: sham-operated rats (sham), ovariectomized control rats (OVX-control), ovariectomized rats supplemented with ethanol extracts of PG seed at 50 mg/kg bw/day (OVX-PS50), ovariectomized rats supplemented with ethanol extracts of PG seed at 200 mg/kg bw/day (OVX-PS200), ovariectomized rats supplemented with ethanol extracts of PG peel at 50 mg/kg bw/day (OVX-PS50), ovariectomized rats supplemented with ethanol extracts of PG peel at 200 mg/kg bw/day (OVX-PP200). PG ethanol extracts were orally supplemented at the level of 1mL per day for 7 weeks. The body weight gain, food intake and food efficiency ratio were not significantly different between groups by t-test. The levels of total-cholesterol and triglyceride in serum were not changed by supplementation of PG ethanol extracts. The level of HDL-cholesterol on serum of the OVX-PS50 and OVX-PS200 groups were similar to the OVX-control group, but the OVX-PP50 and OVX-PP200 groups were higher than sham group. These results suggest that ethanol extracts of PG peel were more effected than those of PG seed.

The aim of this study was to evaluate the effect of Lycii fructus (LF) on serum lipid and the collagen content of the connective tissues in ovariectomized rats. From day 2 until day 37 after the ovariectomy, Sprague-Dawley female rats were randomly assigned to the following groups : sham-operated rat (Sham), ovariectomized control rat (OVX-control), and ovariectomized rats supplemented with the LF 50mg/kg bw/day (OVX-LF). The LF ethanol extract were orally administrated 1ml per day. Body weight gain was not significantly different in groups. Although total-cholesterol and triglyceride were increased in the ovariectomized control, supplementation with the LF extract decreased the levels. Moreover, the serum HDL-cholesterol levels were significantly increased after supplementation with the LF extract(p<0.05). Supplementation with the LF extract prevented a decrease in the collagen level in bone and cartilage tissues. These results are consistent with the conclusions based on the estrogenic activities of LF. Therefore, it may be used to possibly improve the quality of life in menopausal women.

The purpose of this study was to elucidate effects of fructooligosaccharide on gastrointestinal tract and blood lipids of rats when this was supplied as purchased condition or oligosaccharide containing sponge cake. Male Sprague-Dawley rats were assigned to one of 3 treatments 1) control diet 2) 7.5% fructooligosaccharide containing diet (FOS diet) 3) lyophilized sponge cake powder containing diet (FOS-C diet). The sponge cake was made with fractooligosaccharide which replaced 40% of its surose, and the final concentration of fructooligosaccharide in FOS-C diet was 7.5%. Cecal and fecal water contents, amount of cecal content, and cecal wall weight were higher from fructooligosaccharide consumption, whereas total gut transit time was longer in rats consuming fructooligosaccharide compared with those fed control diet. Cecal and fecal pH were lower in FOS and FOS-C groups than in control group. Total cecal SCFA pools were higher from ingesting fructooligosaccharide containing diets compared with control diet. Serum triglyceride levels were lower in rats fed FOS and FOS-C diet than those fed control diet, while serum cholesterol levels were unaffected by treatment. Therefore the effects of fructooligosaccharide in sponge cake on serum lipids and gastrointestinal tract were similar to those of intact fructooligosaccharide. Also, adding 7.5% of FOS accompanied diarrhea symptom which suggests some precaution are needed when using FOS.
