The purpose of this study was to examine the effects of long-term endurance exercise and salvia miltiorrhiza vinegar on body composition and insulin resistance of high-fat diet (30% carbohydrate, 50% fat and 20% protein) induced obese rats. After 8 weeks of high fat diet (50% of total calories), rats were divided into 4 groups (sedentary group, n=10; exercise group, n=10; Salvia miltiorrhiza vinegar group, n=10; exercise+Salvia miltiorrhiza vinegar group, n=10) for 8 weeks. Body weight, body composition, diet intake volume, oral glucose tolerance test, plasma total cholesterol were measured. The results showed that Salvia miltiorrhiza vinegar plus endurance exercise training for 8 weeks significantly improved body weight control, visceral fat weight, and insulin resistance. However, only Salvia miltiorrhiza vinegar treatment did not significantly improve body composition and insulin resistance. In addition, there was no additive by the combination of Salvia miltiorrhiza vinegar and endurance exercise in insulin, body fat, and total cholesterol. The reduction of body fat, glucose, insulin and cholesterol by combination was resulted from the exercise. These results suggest that Salvia miltiorrhiza vinegar has slight effect on anti-hyperglycemia and anti-obesity.

Cheonggukjang and chaga mushrooms have numerous health benefits, and have been used in alternative medicine. Therefore, a powder mixture of 98: Cheonggukjang and 2: Chaga extracts was fermented with Lactobacillus acidophilus KCTC3925 (FCC) and its anti-obesity effects in high-fat diet (HFD)-induced obese mice were determined. Five-week-old male ICR mice were fed a normal diet or HFD in the presence or absence of 3% and 5% FCC by weight (n = 10 per group). After 12 weeks, the mice were sacrificed, and the serum and tissue samples were collected for analysis. Body weight and epididymal fat pad weight were significantly lowered in the 3% and 5% FCC groups compared with those in the HFD control group (p < 0.01). FCC supplementation suppressed serum triglyceride and increased serum HDL-C levels (p < 0.01). Serum GOT, GPT, and leptin levels, hepatic COX-2 mRNA expression, and splenic COX-2 and IL-4 mRNA expression were significantly higher in the HFD groups than in the control group (p > 0.05); however, except for splenic IL-4 levels, the increases were significantly attenuated by FCC supplementation. Expression of ICAM-1, an aortic inflammatory marker, was significantly increased in the HFD group; this effect was suppressed in the 3% FCC group (p < 0.01) but not in the 5% FCC group. FCC suppressed the body weight and epididymal fat pad weight gain, as well as inflammatory responses in the liver and spleen of HFD-fed mice. Thus, FCC supplementation will be beneficial for the treatment of obesity-related effects.

BACKGROUND/OBJECTIVES: Curcuma zedoaria R. (Zingiberaceae) has been used to treat headache, fever, and hypertension-related symptoms in Asian countries, including Korea, China, and Japan. We investigated whether dietary intake of a C. zedoaria extract (CzE) affected atherosclerosis in vivo. MATERIALS/METHODS: Apolipoprotein E-deficient (ApoE^-/-) mice (n = 32) were fed a normal diet (ND), a high-cholesterol diet (HCD), an HCD containing CzE (100 mg/kg/day), or an HCD containing simvastatin (10 mg/kg/day) for 12 weeks. The anti-atherosclerotic effects were evaluated by observing changes in fatty streak lesions, immunohistochemical analysis, ex vivo fluorescence imaging, lipid profiles, and western blot analysis. RESULTS: The CzE-fed group showed a 41.6% reduction of atherosclerosis. Furthermore, CzE significantly reduced the levels of serum triglyceride, high-density lipoprotein, the chemokine (C-X3-C-motif ) ligand 1, the adhesion molecules vascular cell adhesion molecule-1, intracellular adhesion molecule-1, and E-selectin; down-regulation of tumor necrosis factor-α, interleukin-6, high mobility group box-1, and cathepsin levels in the aortic sinuses and aortas of ApoE^-/- mice were also observed. CONCLUSIONS: The results suggest that the inclusion of a water extract of C. zedoaria in a HCD is closely correlated with reducing the risk of vascular inflammatory diseases in an ApoE mouse model.

This study was conducted to investigate the effects on fermentation characteristics of rumen microorganism by different types and levels of lignosulfonate treated soybean meal (LSBM) in in vitro test and rumen simulation continuous culture (RSCC) system in dairy cows. The experiment I was control and 12 treatments (each with 3 replications) in vitro test to demonstrate composition of different types of treatments with lignosulfonate (Desulfonate, Na, Ca and solution) and levels (2, 4 and 8%) of soybean meal in the dairy cow diet. LSBM source treatments in the dairy cow diet showed pH value, $NH_3$-N concentration and total VFA concentration lower than control at all levels and incubation times (p<0.05). Dry matter digestibility of LSBM source treatments showed lower than control (p<0.05). Gas production and rumen microbial synthesis was decreased by rumen microbial fermentation for incubation times. Undegradable protein (UDP) concentration of all LSBM treatments was decreased for incubation times, and significantly higher than control (p<0.05). In the experiment II compared diets of the control, LSBM Na 2%, LSBM Sol 2%, which are high performance to undegradable protein (UDP) concentration experiment I in vitro test, and heated treatment lignosulfonate (LSBM Heat) 2% in the dairy cow diet from four station RSCC system ($4{\times}4$ Latin square). A rumen microbial fermentation characteristic was stability during 12~15 days of experimental period in all treatments. The pH value of LSBM treatments was higher than control treatment (p<0.05). The $NH_3$-N concentration, VFA concentration and rumen microbial synthesis of LSBM treatments were lower than control (p<0.05). The undegradable protein (UDP) showed LSBM Na 2% (45.28%), LSBM Sol 2% (43.52%) and LSBM Heat 2% (43.49%) higher than control (41.55%), respectively (p<0.05). Those experiments were designed to improve by-pass protein of diet and milk protein in the dairy cows. We will conduct those experiments the in vivo test by LSBM treatments in dairy cows diet.

The purposes of this study were to investigate effects of Bambusae Caulis in Liquamen(BCL) on antioxidant activities and inhibitory activities of HMG-CoA reductase of in vitro, and lipid metabolism in rats fed the high cholesterol diet in vivo. Sprague-Dawley male rats weighing l00$\pm$10 g were devided into five groups ; normal group(NOR), the high cholesterol diet administered group(1 $\%$ cholesterol and 0.25$\%$ sodium cholate)(CON), 5$\%$ BCL administered group (5BL), the high cholesterol diet and 5$\%$ BCL administered group (5BCB) and the high cholesterol diet and 10\$\%$ BCL administered group (10BCB), respectively. In antioxidative activities of BCL using Rancimat in vitro, 1.25 diulent and original solution were more excellent activities than the control group, and in inhibiting activities of HMG-CoA reductase, BCL was shown inhibitory effects compared with the control, in dose dependent manners, especially 57.9$\%$ in original solution and 36.0$\%$ in 1.25 diulent. The growth rate of the control group was higher than the normal group, wheras the group given 5$\%$ BCL and 10$\%$ BCL were gradually decreased, especially the most excellent effect in 10$\%$ BCL. Serum levels of total cholesterol, LDL-cholesterol, triglyceride and free cholesterol were significantly decreased, whereas levels of HDL-cholesterol and phospholipid were increased, but not significantly. BCL administered group was increased in HDL-cholesterol/total cholesterol ratio and lowered antherogenic index. The activities of AST in serum were rather lowered in the BCL administration group than the cholesterol diet group, but not in ALT and ALP. The hepatic contents of total cholesterol were lowered significantly than control group, but not in triglyceride. Therefore, it might be expected that BCL is believed to be a possible protective or curative effects for fatty livers and hyperlipidemia-induced by a hi~h cholesterol diet.

This study was conducted to investigate the effects of dietary silicate minerals on ammonia emission from the excreta and performance in laying hens. A total of one thousand and twenty 49 week-old Lohmann brown layers were divided into three treatment groups consisting two replicates of 170 birds each. The experimental diets were containing three kinds of silicate minerals (Sand, Na-bentonite and SY feldspar) added at the level of 2% by top-dressing. Ammonia emission from the excreta was significantly decreased (p<0.05) by the supplementation of Na-bentonite or SY feldspar. N concentration of the excreta was significantly higher (p<0.05) for the hens fed Na-bentonite or SY feldspar compared to those fed sand. However, no significant differences were observed in feed intake and laying performance with over 80% laying rate observed for all the treatments. Egg shell strength was diminished when SY feldspar was added to the diet. As a whole, the results obtained from the experiment indicated that supplementation of Na-bentonite or SY feldspar added at 2% to the laying hen diet should not affect laying performance but help to reduce ammonia from the excreta at the same time.

This experiment was carried out to investigate the effect of feeding limestone to high and low Ca layer diets on laying performance and eggshell quality in laying hens. Five hundred and twenty-eight HyLine brown layer allotted to six treatments consisting of high and low Ca diets. Limestone added to two kinds of basal diet with 1, 2 and 3 fold compared to conventional diet. Egg production was not different regardless Ca level and amount of added limestone in overall periods. However, the increment of egg observed in high Ca diet and added 10g limestone group during later period. Ca and limestone intake were increased as increasing feeding limestone. Eggshell strength and thickness were improved in high Ca consumption group. It was concluded that feeding Ca sources to conventional diets was helpful improving eggshell quality and reducing feed cost per egg mass by increasing proportion of Ca intake.

Background: Korean Red Ginseng extract (KRG, Panax ginseng Meyer) and its constituents have been used for treating diabetes. However, in diet-induced obese mice, it is unclear whether KRG can enhance the glucose-lowering action of rosiglitazone (ROSI), a peroxisome proliferator-activated receptor gamma synthetic activator. Methods: Oral glucose tolerance tests (oGTTs) were performed after 4 days of treatment with a vehicle (CON), KRG [500 mg/kg body weight (b.w.)], ROSI (3.75 mg/kg b.w, 7.5 mg/kg b.w, and 15 mg/kg b.w.), or ROSI and KRG (RK) in obese mice on a high-fat diet. Adipose tissue morphology, crown-like structures (CLSs), and inflammation were compared by hematoxylin-eosin staining or quantitative reverse transcription polymerase chain reaction. Results: The area under the glucose curve (AUC) was significantly lower in the RK group (15 mg/kg b.w. and 500 mg/kg b.w. for ROSI and KRG, respectively) than in the CON group. There was no significant difference in the AUC between the CON and the other groups. Furthermore, the AUC was significantly lower in the RK group than in the ROSI group. The expression of the Ccl2 gene and the number of CLSs were significantly reduced in the RK group than in the CON group. Conclusion: Our results show a potential enhancement of ROSI-induced improvement of glucose regulation by the combined treatment with KRG.

Chaga mushroom and Cheonggukjang have been used in alternative medicine. In this study, we determined the anti-obesity effects of fermented Chaga-Cheonggukjang (FCC), an extract prepared by secondary fermentation of a mixture of Cheonggukjang and Chaga by Lactobacillus acidophilus on highfat diet (HFD)-induced mice. Male ICR mice were fed a normal diet or HFD in the presence or absence of 3% and 5% FCC (FCC3 and FCC5). After 3 months, the mice were sacrificed, and serum and tissue samples were examined. Body weight and epididymal fat pad (EFP) weight were significantly lowered in FCC3 and FCC5 groups compared to those in the HFD control group. FCC supplementation suppressed serum triglyceride (TG) and increased serum HDL levels. Serum GOT, GPT, leptin levels and hepatic COX-2 mRNA expression were significantly higher in the HFD groups, and these increases were significantly attenuated by FCC supplementation. FCC suppressed body weight and EFP weight gain, as well as inflammatory responses in the liver in HFD-fed mice. Thus, FCC supplementation may have protective effects for obesity-related disease.

Forty-wk-old 480 ISA Brown layers were used in a 10-wk feeding trial to investigate the effects of additional various levels of limestone to a low calcium diet without any calcium additives on the performance of laying hens. There were significant differences in average egg weight (P<0.05) without any specific trend among treatments and hen-day egg production was not influenced by the dietary treatments. Daily intake and conversion per kg egg of feed excluded the calcium supplement were significantly reduced (p<0.05) as the level of additional calcium supplement increased in both types of layer diet, while those of feed included the calcium source were significantly increased (P<0.05) as the level of additional calcium supplement increased. Egg specific gravity, eggshell breaking strength and thickness were increased as the level of additional calcium supplement increased, however the significant differences were found only in egg specific gravity It would be possible to reduce the daily feed intake and feed conversion and to improve the eggshell quality by feed the low calcium diet devoid of calcium supplement from the conventional laying hen diet and by supply the additional calcium source at 3 to 4 p.m. instead of the continuous feeding of conventional high calcium diet.
