한약에서 사용하는 유황은 인체에서 열을 발생하는 물질로서 에너지 소모를 일으킨다. 청피,시호, 지실 등의 한약재는 이기(理氣), 조습건비(燥濕健脾), 이수삼습(利水渗濕), 활혈거어 (活血祛瘀)의 효능이 있어서 비만을 치료하는 약물로 한의학에서 이용되고 있다. 본 연구에서는 유황을 함유하는 항비산이 실험동물의 체중을 감소시키는데 도움이 될 것으로 가정하고 항비산을 흰쥐에 투여한 후 체중감량 및 혈액지질조성에 미치는 효과를 조사하였다. 4주령의 SD계 흰쥐에 9주 동안 10% 항비산이 함유된 고지방식이와 대조군으로서 10% cellulose가 함유된 식이를 공급하였다. 유황이 주로 함유된 한약재인 항비산을 섭취하는 동안 흰쥐의 건강상태는 양호하였다. 항비산은 흰쥐를 생육하는 동안 고지방식이와 병행 공급 시 10% cellulose가 갖는 정도의 체중감소효과를 나타냈다. 혈중 총 콜레스테롤과 중성 지방은 감소하고 HDL-콜레스테롤은 증가하여 혈중지질 조성을 개선시키는 작용이 있었다. 또한 흰쥐의 간 기능에는 독성을 나타내지 않았다. 따라서 임상연구를 포함한 더 많은 연구가 필요하지만 이상의 결과로 본 실험에서 사용한 항비산은 혈액지방 조성을 개선하여 비만인의 체중감량에 이용될 수 있을 것으로 사료된다.

The effect of red pepper powder (RPP) or kimchi on body weight and blood and tissue lipids was evaluated in male Sprague-Dawley rats fed a high fat diet (HFD). RPP (0.006% capsaicin) diet contained 5% RPP in HFD; the kimchi diet was 10% kimchi (50% RPP by dry weight) in HFD. Food consumption of the RPP and kimchi diet groups was not different than the normal or HFD groups, but final body weights were significantly lower than the HFD group (p <0.05) after 4 weeks on the RPP or kimchi diets. The weights of liver, epididymal fat pad and perirenal fat pad in RPP and kimchi diet groups were lower than those of the HFD group, but the rats on the kimchi diet had even lower weights than those on the RPP diet. Plasma concentrations of triglyceride and cholesterol were lowest in the kimchi diet group (p<0.05). The RPP and kimchi diet groups had lower total lipids, triglycerides and cholesterol in liver; as well as in tissue fat prods than the HFD group, with the greatest effect being in the kimchi diet group. These results suggested that RPP and kimchi consumption can reverse the effects of HFD on weight gain and blood and tissue lipids, and that kimchi does so more effectively than RPP alone.

Effects of garlic on hypocholesterolemia, anticoagulation and hypoglycemia were studied in the present experiments using male rats. The results were summarized as follows. 1. The supplementation of $2{\sim}4%$ garlic to 2% cholesterol diets did not affect food intake and weight gain in male rats. 2. Rat's groups fed the diets supplemented with $2{\sim}3%$ garlic (C.D.E.F) to 2% cholesterol diet (B) decreased serum total cholesterol levels by $16{\sim}32%$, triglyceride levels by $18.6{\sim}26.8%$ and ${\beta}/{\alpha}-lipoportein$ rations by $42{\sim}58%$, but increased HDL-cholesterol levels by $29{\sim}65%$ as compared to B group, and so the author assumes that garlic supplementation exerts hypocholesterolemic effect on cholesterol - fed rats because of the increase of HDL and HDL - cholesterol levels. 3. Rat's groups fed the diets supplemented with $2{\sim}4%$ garlic (C.D.E.F) to 2% cholesterol plus 0.25% bile salt diet (B) increased whole blood coagulation times, prothrombin times and fibrinolytic activities, but decreased plasma fibrinogen levels as compared to B group, and so the author assumes that garlic supplementation exerts anticoagulative effect because of the inhibition of fibrinogen synthesis in male rat's liver. 4. Rat's groups fed the diets supplemented with $2{\sim}4%$ garlic (B.C.D.E) to standard diet (A) decreased serum glucose levels by $1{\sim}24%$, but increased serum insulin concentrations by $0.5{\sim}3.0$ times as compared to A group, and so the author assumes that garlic supplementation exerts hypoglycemic effect because of the increase of serum insulin levels by stimulation pancreatic secretion of insulin from ${\beta}-cells$ in the islets of Langerhans.

We evaluated the effects of rice distillers dried grain (DDG) as a partial replacement for fish meal in the practical diet on growth performance, feed utilization, and body composition of juvenile olive flounder Paralichthys olivaceus. Six isonitrogenous and isocaloric diets were formulated to contain 0%, 7%, 14%, 21%, 28%, and 35% DDG (designated DDG0, DDG7, DDG14, DDG21, DDG28, and DDG35, respectively). Three replicate groups of juvenile olive flounder averaging $9.6{\pm}0.2g$ were fed one of the experimental diets to visual satiety twice daily for 8 weeks. Neither survival nor daily feed intake was affected by the dietary DDG levels. Weight gain of the flounder fed the DDG28 and DDG35 diets was lower than that of flounder fed the DDG7 diet. The feed efficiency of flounder fed the DDG28 diet was lower than that of flounder fed the DDG0, DDG7, and DDG14 diets. The protein efficiency ratio of flounder fed the DDG28 diet was lower than that of flounder fed the DDG7 diet. The proximate composition of muscle was not affected by the dietary DDG levels. The plasma contents of total protein, glucose, cholesterol, glutamate oxaloacetate transaminase, phospholipid, and triglyceride were not affected by the dietary DDG levels. The results of this experiment suggest that DDG has the potential to replace fish meal and could be used up to 21% DDG without any negative effects on the growth and feed utilization of juvenile flounder.

A total of 800 one-day-old chickens (Cobb 500) were obtained from a local hatchery and allocated randomly to five dietary treatments. This study conducted for 42 d. Treatment groups included 1) CON (control), 2) T0.3 (0.3% of thyme extract), 3) T0.6 (0.6% of thyme extract), 4) G0.3 (0.3% of garlic extract) and 5) G0.6 (0.6% of garlic extract). Thyme extract included $90{\mu}g/ml$ Carvacrol and 400 mg/ml thymol while garlic extract included 100 mg/ml elastin. There were no significant effects among the treatments on weight gain, feed intake and feed conversion ratio over the entire trial. Also, no significant differences were observed between CON group and other treatments in plasma parameters (cholesterol, triglyceride and HDL) and hematocrit. Sex of chickens had no effect on blood parameters. Supplementation of herb extracts did not affect carcass characteristics including carcass yield, breast, thigh and abdominal fat. There were no significant differences observed in carcass characteristics between males and females fed with different levels of herb extracts. In conclusion, supplementation of garlic and thyme extracts as feed additives at two levels of 3 and 6% in the present study did not improve performance and carcass traits of broiler chicks.

The present work is aimed to evaluate the protective effect of glutathione-enriched Saccharomyces cerevisiae FF-8 strain on carbon tetrachloride ($CCl_4$)-induced hepatotoxicity and oxidative stress in rats. The activities of liver markers (alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, lactate dehydrogenase), lipid peroxidative index (thiobarbituric acid-reactive substances), and the antioxidant status (reduced glutathione) were used to monitor those protective roles of FF-8 strain. The liver marker enzymes in plasma and the lipid peroxidation in the liver were increased when $CCl_4$ was treated but these were significantly decreased by FF-8 strain treatment. The hepatic concentration of glutathione in the current glutathione-enriched FF-8 strain fed animal was approximately twice as high as the normal, but this was slightly increased in response to $CCl_4$ plus glutathione-enriched FF-8 strain. The increased liver triglyceride concentration due to the $CCl_4$ treatment was significantly decreased by FF-8 strain and the reduced level reached to that of normal group. Administration of FF-8 strain in normal rat did not show any signs of harmful effects. Therefore, the current findings suggest that FF-8 strain could be an effective antioxidant with no or negligible side-effects and it might be useful for the purpose of protection treatment of hepatotoxicity and oxidative stress in $CCl_4$-treatment in rat.

본 연구는 해조류에 존재하는 황산기를 함유하고 있는 후코이단의 급성 알코올 간 손상 모델에서의 간 보호능을 관찰하였다. 실험 결과 후코이단은 급성으로 알코올을 섭취시킨 쥐의 체중감소를 억제시켰으며, 알코올 섭취를 통해 나타날 수 있는 중성지질, 콜레스테롤, LDL-콜레스테롤 상승을 유의적으로 감소시킨 것으로 나타났다. 또한 간 기능을 대표하는 혈중의 GOT는 유의적인 차이는 없었으나, GPT는 유의적으로 후코이단 경구투여에 의해 감소되었다. 또한 후코이단은 지방이 비대해 지는 현상과 간세포의 지방축척을 감소시킨 것으로 관찰되었다. 따라서 이러한 결과로 보아 후코이단은 급성 알코올 섭취에 의한 간손상을 완화시켜 줄 수 있는 식품소재로 활용가능하다고 사료된다.

Objectives: Recent data have revealed that the plasma concentration of inflammatory mediators is increased in the insulin-resistant states of obesity and type 2 diabetes. The purpose of this study was to investigate the antidiabetic and anti-obesity effect of Massa Medicata Fermentata on obese type 2 diabetes mice. Methods: In order to examine the effects of Massa Medicata Fermentata, obese type 2 diabetes mice induced by Surwit's high fat, high sucrose diet. Mice were divided into 4 groups of ND (normal diet), HFD (high fat and high sucrose diet), Met (high fat and high sucrose diet with metformin) and MMF (high fat and high sucrose diet with Massa Medicata Fermentata) and investigated over 8 weeks. Diabetic and obese clinical markers, including body weight, glucose level, lipid level, leptin concentration, epididymal fat pad and liver weights and adipose tissue macrophage (ATM) were determined. Results: Compared with the HFD group, body weight, fructosamine, triglyceride, epididymal fat pad weight and ATM were significantly reduced in the MMF group. Conclusions: From the above results, the intake of Massa Medicata Fermentata may be effective in anti-hyperglycemia and anti-obesity by the attenuation of glucose and lipid levels and also inflammation state. Massa Medicata Fermentata may be beneficial for controlling diabetes mellitus type 2 in humans.

Capsaicin is a pungent component of red pepper, which is widely consumed as food adjuncts. The present study was performed to investigate anti-obesity effects of capsaicin in diet-induced obese rats. Male Sprague-Dawley rats (n=14) were fed with a high-fat diet (Control) or high-fat diet containing 0.016% capsaicin (w/w) (Capsaicin) for 8 weeks. The final body weight and the mass of white adipose tissue were significantly lower in capsaicin supplemented group compared to control. Dietary capsaicin ameliorated lipid profiles with decrease in the plasma concentrations of triglycerides and total cholesterol, and decrease in the levels of total lipids and triglycerides in the liver. Activity of glycerol-3-phosphate dehydrogenase (GPDH), an indicator of triglyceride biosynthesis in white adipose tissue, decreased by 35% in the group supplemented with capsaicin. However, consumption of capsaicin increased the expression of uncoupling protein 2 (UCP2) in white adipose tissue, which is related to energy consumption. Our data suggests that capsaicin may reduce body weight and fat accumulation in high fat diet-induced obese rats. These effects may be mediated, at least partially, by the upregulation of UCP2 gene expression and its ability to inhibit GPDH activity.
