This study investigated anti-obesity and antioxidant effects of dietary non-fermented soybean crud residue (SCR) and fermented SCR by Monascus pilosus (FSCR) in high-fat induced-obese mice. SCR and FSCR were supplemented with high-fat diet at 2% (wt/wt) dose for 8 weeks. Both SCR and FSCR significantly lowered body weight, epididymal fat weight and weight gain rate compared to high-fat diet control (HC) group and FSCR group showed lowest weight gain rate. In addition, it was observed that serum and hepatic lipid profiles including triglyceride, total cholesterol, LDL-cholesterol and HDL-cholesterol were significantly improved by supplementing SCR or FSCR. Furthermore, SCR and FSCR administration showed increase of glutathione content and decrease of hepatic lipid peroxide content, serum aminotransferase activity, and hepatic xanthine oxidase activity. On the other hand, activities of reactive oxygen species scavenging enzyme such as superoxide dismutase, glutathione S-transferase and glutathione peroxidase in two test groups were higher than those of HC. Lastly, in comparison with SCR, FSCR was more effective in restoring obesity-related biomarkers to normal level in high-diet induced obese mice. In conclusion, the present study indicates that FSCR could have not only anti-obese effects such as inhibition of abdominal fat accumulation, but also protective effects of cardiovascular disease such as atherosclerosis by decreasing serum and hepatic lipid contents. Furthermore, these results suggest that experimental diets in this study could alleviate hepatic damage caused by overproduction of reactive oxygen spices (ROS) due to obesity via inhibition of ROS generating activities and induction of ROS scavenging activities.

This study was conducted to evaluate the effect of Sikhe made by medicinal herb on the functional level of liver. Water extract I (12.9% W/W) and II (25.8% W/W) were obtained from medicinal materials: Caragana Sinica, Glycyrrhiza uralensis, Atractylodes rhizoma alba, Atractylodes rhizoma alba, Crataegus pinnatifida, Paeonia lactiflora Pasll., Hordeum vulgare Linne, Oryza sativa Linne, ginger, peer and jujube. Experimental groups were divided into the control diet group (C), high fat diet group (HF), high fat diet treated with 5% extract I group (HFE I ) and high fat diet treated with 5% extract II group (HFE II). In sensory evaluation, overall quality scores associated with color, aroma, flavor and taste were significantly higher in water extract II than in water extract 1. After investigating functional and lipid levels of livers in rats, we found that the administration of water extract I or water extract II to the high fat diet group (HF) did not affect the gain of body weight but mildly reduced GOT or GPT activity in the high diet group. Moreover, administration of these medicinal herbal extracts significantly decreased the levels of total lipid, triglyceride and total cholesterol in the high fat diet group (HF). However, administration of these medicinal herbal extracts did not affect the level of phospholipid. In conclusion, as Sikhe made by medicinal herb slightly decreased the activity of GOT or GPT and amount of lipid in liver, prevention against high fat diet is thought to be important for liver protection.

The purpose of this study was to compare the effects of either aerobic exercise or polyphenols supplementation on mRNA expression of endoplasmic reticulum stress in skeletal muscle of high fat diet-induced obese mice. In the study, mice were divided into five groups: (1) NC (normal diet for 16 weeks as a control, n=10), (2) HC (high fat diet for 16 weeks as a control, n=10), (3) H-Re (high fat diet with resveratrol 25 mg/kg supplementation for 16 weeks, n=10), (4) H-Ch (high fat diet with chrysin 50 mg/kg supplementation for 16 weeks, n=10), and (5) HE (high fat diet with aerobic exercise for 16 weeks, n=10). Aerobic exercise was performed on a treadmill for 40~60 min/day at 10~14 m/min, 0% grade, four days/week for 16 weeks. Endoplasmic reticulum stress related genes were measured by real-time polymerase chain reaction. ATF6, PERK, $IRE1{\alpha}$, and BIP/GRP78 mRNA were significantly decreased in HE compared with those in HC (p<0.05). Also, ATF6, $IRE1{\alpha}$, and BIP/GRP78 mRNA were significantly decreased in H-Re compared with those in HC (p<0.05). ATF6 mRNA was significantly decreased in H-Ch compared with that in HC (p<0.05). These findings suggest that aerobic exercise, resveratrol, and chrysin supplementation changed ER stress markers. However, aerobic exercise was most effective on ameliorating the high fat diet induced ER stress markers. Thus, it seems that aerobic exercise might have a more positive effect on skeletal muscle endoplasmic reticulum stress compared with polyphenol supplementation in high fat diet-induced obese mice.

The effect of liquid cultures of Cordyceps militaris (LCM) on weight gain, food intakes, food efficiency ratios, serum and hepatic lipids, fecal lipids excretion, serum protein and enzyme activities, were investigated in adult female rats (30 weeks old). Sprague-Dawley rats were assigned to one normal and four hyperlipidemic diet groups, Hyperlipidemic diet groups (20% fat, 1% cholesterol) were divided into high fat diet (LCM free water), 10%, 20% or 30% LCM diet groups (10%, 20% or 30% LCM in water) according to the levels of LCM supplementation. After 35 days of experimental diet consumption, the body weight gains, hepatic weights, and food efficiency ratios of the rats fed hyperlipidemic diets were significantly increased compared with those of the rats fed normal diet. The concentrations of serum and hepatic triglycerides, hepatic total lipid, and atherogenic index of the rats fed 20% or 30% LCM diets were significantly lower than those of the rats fed the high fat diet. The concentration of serum HDL-cholesterol of the rats fed all LCM diets was significantly higher than those of the rats fed the high fat diet. The fecal excretion of triglyceride in the rats fed 20% or 30% LCM diets was significantly higher than those of the rats fed high fat diet. The concentrations of serum and hepatic total cholesterol, serum LDL-cholesterol, and HDL-cholesterol/total cholesterol ratio, fecal excretion of cholesterol, and the activities of serum glutamic pyruvic transaminase and alkaline phosphatase of the rats fed all LCM diets were similar to those of the rats fed high fat diet. No differences were noted in the weights of kidney and femur, the serum concentration of glucose, total protein and albumin, and the activities of glutamic oxaloacetic transaminase and ${\gamma}$ -glutamyltranspeptidase, among the rats on all the experimental diets. These results showed that the 20% or 30% LCM diets feeding decreased the serum and hepatic triglycerides, and the atherogenic index, and increased the serum HDL-cholesterol of the adult female rats.

부산광역시는 대한민국 바다의 관문이다. 인천 팔미도가 현존하는 최초의 등대임을 부인할만한 역사적 자료는 거의 없으나. 우리나라의 고지도를 살펴보면 그 이전 등대의 흔적들을 쉽사리 확인할 수 있다. 그리고 일제강점기 이전 대한제국의 역사는 팔미도 등대 빠른 시기에 부산항에 설치된 등대 존재를 강력히 나타내고 있다.
