Naringin has antioxidant and antihyperlipidemic properties, however, phenolic compounds including naringin are unstable in the presence of light, heat and oxygen. Beta-cyclodextrin ($\beta$-CD) is a cyclic heptamer composed of seven glucose units that enhances the stability and solubility of molecules through the formation of inclusion complexes. This study was conducted out to compare the effects of CD-naringin (CD-N) inclusion complexes with naringin on lipid metabolism in high fat-fed animals. Male C57BL/6 mice were fed either CD-N (0.048%, w/w) or naringin (N, 0.02%, w/w) in a 20% high-fat (HFC, 15% lard, 5% corn oil, w/w) diet for 10 weeks. Orlistat (Xenical, 0.01%, w/w) was used as a positive control (PC). There were no differences in body weight, food intake, liver and heart weights, plasma triglyceride(TG), leptin, adiponectin, resistin, IL-$1{\beta}$ and IL-6 concentrations, and hepatic $\beta$-oxidation, carnitine palmitoyl transferase(CPT), glucose-6-phosphate dehydrogenase (G6PD) and malic enzyme activities between the HFC and CD-N groups or between the HFC and N groups. However, both CD-naringin and naringin supplementation les to a significant reduction in the epididymal and perirenal white adipose tissue weights, plasma free fatty acid, insulin and blood glucose concentrations, hepatic cholesterol and TG contents and hepatic fatty acid synthase (FAS), phosphatidate phosphohydrolase (PAP) and HMG-CoA reductase activities compared to the HFC group. The plasma HDL-cholesterol concentration was significantly higher in CD-N and N groups than in HF and PC groups. These results indicate that both CD-naringin and naringin supplementation effectively improved plasma and hepatic lipid metabolism without differences between CD-N and naringin groups.

This study was conducted to investigate the effects of dietary resveratrol on growth performance, blood biochemical parameters, immunoglobulin, and blood antioxidant activity in broiler chicks. Three hundred twenty one-day old broiler chicks were divided 8 treatments (C(-), basal diet; C(+), basal diet with antibiotics; DL-${\alpha}$-tocopherol 20 IU; DL-${\alpha}$-tocopherol 200 IU; resveratrol 20 ppm; resveratrol 200 ppm; methylated resveratrol 20 ppm; methylated resveratrol 200 ppm) with 4 replicates and 10 birds per replicate. Birds were reared for 35 days, and, at the age of 35 days, eight birds of average weight from each replicate were selected for blood samples collection. There were no significant differences on feed intake and feed conversion ratio. But final body weight and weight gain in antibiotics, resveratrol and methylated resveratrol treatments were significantly higher than no-antibiotics and ${\alpha}$-tocopherol treatments (P<0.05). There were no significant differences on carcass rate and relative organ weights among treatments, however, weights of liver and bursa of februcius in antibiotics, resveratrol and methylated resveratrol treatment were lower than other treatments. Weight of pancreas was high in resveratrol and methylated treatment. On the cecal microflora (total microbes, Coliform bacteria, Salmonella spp., and lactic acid bacteria), these in resveratrol and methylated resveratrol treatments didn't show the differences compared with those in no-antibiotics, antibiotics, and ${\alpha}$-tocopherol treatments. In the serum, there were no significant differences on creatinine, blood urea nitrogen (BUN), total protein, albumin, globulin, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) among treatments, though globulin contents of reseveratrol 200 ppm and methylated resveratrol 20 ppm treatments decreased compared to those of other treatments. Immunoglobulin (IgA, IgG and IgM) were significantly decreased in antibiotics and resveratrol treatments compared to that of no-antibiotics and ${\alpha}$-tocopherol treatments (P<0.05). Superoxide dismutase (SOD) like activity tended to increase in resveratrol groups (P<0.05), however, there was no significant difference on malondiakdehyde (MDA) content among treatments. In conclusion, these results showed that resveratrol derived from mulberry can be used as alternative of antibiotics through improvement of broiler's performance and maintain of health.
This study was performed to examine antitumor activities of Rubus coreanus Miquel and Angelica gigas Nakai extracts against sarcoma-180 and anti-stress activities in ICR mice. The variation of body weights of the 20 days of Rubus coreanus extracts-administrated mice group was very low. The survival rate (T/C %) of Rubus coreanus extract administrated group was 161% after 50 days from the inoculation of sarcoma-180 and the increment of their body weights was suppressed. Anti-stress effect of the extracts of R. coreanus and A. gigas were estimated by maeasuring blood chemical value and internal organs weight in ICR mice. The extracts of R. coreanus reduced the cholesterol and glucose to the normal level in the all stress animal models. The extracts of R. coreanus reduced the hypertrophy of the internal organs such as adrenal, spleen and liver to the regular level.

Teratogenic and embryotoxic effects of mercury have been reported, however, there is little information about possible antidotes against mercury exposure during gestation. In order to evaluate therapeutic effects of selenium as an antidote against mercury poisoning, pregnant CD-1 mice were exposed to methylmercury chloride(20ppm) through the drinking water with treatment of sodium selenite (1.0mg, 2.0mg or 3.0mg/kg b.w., subcutaneously) or BAL(5.0mg/kg b.w., subcutaneously) under the single or combination base as the therapeutic agents from day 6 to 15 of gestation. Fetal growth parameters such as body weight and crown-rump length in the mice exposed to mercury, were reduced as was placental weight compared to those in the control. Treatment of selenium(alone, combination with BAL) reduced the harmful effects induced by mercury on the fetal growth parameters even though no specific relationship between dose and therapeutic effect. The incidence of dead fetuses/resorptions and malformed fetuses(especially cleft palate) was also increased in the mercury only treated group. Selenium treatment demonostrated reduced the incidence of abnormal fetuses under the exposure of mercury. Relative maternal organ weights(liver, kidney, spleen) were increased significantly but relative brain weight was decreased as evidenced by decreased in the mercury treated mice compared to that in the control. A subtle indication of maternal mercury toxicity evidenced by changes of relative maternal organ weights, decreased water and feed consumption were also prevented efficiently by selenium treatment. The present study suggests that methylmercuric chloride is embrytoxic and teratogenic in CD-1 mice when exposured during organogenesis and that selenium administration may have therapeutic application for the treatment of mercury poisoning although more applicable study in human should be performed with caution in the future.
The effects of dietary supplementation of dried coffee meal (CM) on growth performance, blood biochemical profiles, the weights of immune-related organs, and the antioxidant defense system in broiler chicks were examined. A total of 162, 3-day-old male broiler chickens were assigned to three dietary groups: control group (CON), control diet added with 0.5% CM (CM0.5), and control diet added with 1.0% CM (CM1.0). In vitro antioxidant activity test, coffee extracts showed concentration-dependent increase in radical scavenging activity. Dietary addition of 0.5 and 1.0% of CM did not have negative effects on growth performance and feed conversion during the experimental periods, whereas dietary CM significantly (P<0.05) increased the relative weight of thymus without changes in the other organ weights. In addition, birds fed the diet supplemented with CM (0.5 and 1.0%) significantly increased blood albumin without affecting other components including glucose, triglyceride and cholesterol compared with those fed control diet. In antioxidant defense system, the specific activities of superoxide dismutase, glutathione peroxidase and glutathione S-transferase and the level of glutathione in the small intestine and liver were not affected by dietary supplementation of CM. However, hepatic lipid peroxidation in birds fed the diet supplemented with 0.5% CM was significantly (P<0.05) decreased compared with that in control birds. In conclusion, dietary supplementation of CM(0.5~1.0%) has potential for use as a natural antioxidant source without negative effect on growth performance in broiler chickens.

This experiment evaluated the interaction effect of extreme heat diet(EHD), inverse lighting, and cool water on the growth performance of broiler chickens under extreme heat stress. There were 4 experimental groups (T1: EHD 1, 10:00-19:00 dark, 19:00-10:00 light, cold water $9^{\circ}C$; T2: EHD 2, 10:00-19:00 dark, 19:00-10:00 light, cold water $9^{\circ}C$; T3: EHD 1, 09:00-18:00 dark, 18:00-09:00 light, cold water $14^{\circ}C$; T4: EHD 2, 09:00-18:00 dark, 18:00-09:00 light, cold water $14^{\circ}C$), each group composed of 25 broilers and the experiment was repeated 3 times. EHD 1 contained soybean oil, molasses, methionine and lysine. EHD 2 contained all nutrients of EHD 1 and vitamin C additionally. As a result, T1 and T2 displayed higher body weight increase and diet intake compared to T3 and T4 (p<0.05). The weights of their liver and gizzard were similar but the weights of the thymus and bursa F were higher for T1 and T2 compared to that of T3 and T4 (p<0.05). It was observed that T1 and T2 displayed higher concentrations of blood triglyceride, total cholesterol, HDL-C and blood sugar compared to that of T3 and T4 but LDL-C level was higher for T3 and T4 compared to that of T1 and T2 (p<0.05). T1 and T2 displayed higher levels of immunity substances such as IgG, IgA and IgM compared to T3 and T4 but the blood level of corticosterone displayed to be lower for T1 and T2 compared to T3 and T4 (p<0.05). The T1 and T2 contained a higher amount of fecal lactobacillus compared to that of T3 and T4 but the T3 and T4 contained a higher amount of fecal E. coli, total aerobic bacteria, coliform bacteria compared to that of T1 and T2 (p<0.05). T1 and T2 displayed higher concentrations of cecal acetic acid, propionic acid and total short chain fatty acids compared to T3 and T4 but T3 and T4 displayed higher concentrations of butyric acid, isobutyric acid, valeric acid and isovaleric acid compared to T1 and T2 (p<0.05). These results have been observed that broiler chickens exposed to extreme heat stress with feeding EHD, inverse lighting and cold water would improve blood lipid, and elevate the production of immunity substance, beneficial microorganisms, and short chain fatty acids. This provision would also reduce the blood sugar consumption rate as energy sources and these effects will improve the growth performance of the broilers exposed to extreme heat.

The present study was designed to examine the effect of dietary fish oil on blood pressure and lipid status of serum. Weanling SHRs and normotensive Wistars were fed a diet containing 5%(w/w) mackerel oil(MO), soybean oil(SO) or beef tallow(BT) for 8 weeks. Growth rate was not significantly different among three dietary groups, but that of SHRs was silightly lower than that of Wistars. SHRs showed higher systolic blood pressure than Wistar rats from the beginning and become hypertensive (over 150mmHg) after 6 week s of feeding period. The MO group of SHRs showed the lowest blood pressure at the 8th week of feeding period but that of Wistars showed similar values with other groups. Tissue weights of liver, heart and kidney were not different amongdietary aroups in Wistars and SHRs. However, heart and kidney weights of SHRs were significantly higher than those of Wistars. Microscopic examination revealed that endomysium of heart tissue and urinary space of kidney were narrowed in SHRs. Serum total and HDL-cholesterol showed similar values among three different dietary fat groups but triglyceride levels were significantly low in MO groups. HDL-cholesterol levels of SHRs were lower than those of Wistars, as well as the fractions of total HDL, the sum of HDL and $HDL_{2+3}$, while VLDL fractions were higher in SHRs. MO groups had the lower values of $HDL_1,\;HDL_{2+3}$ratio than SO and BT groups. Major dietary fatty acids were more or less incorporated into serum phospholipid and triglyceride, resulting in the characteristic fatty acid profile of each dietary group. Incorporation of $C_{18:2}({\omega}_6)$ in SO groups were pronounced, but the degree of incorporation was lower in SHRs. In Mo groups, $C_{22:6}({\omega}_3)$ levels were inreased in triglyceride. It is suggested that these changes in serum lipid fatty acid composition are related to the different patterns of serum lipid by alteration of dietary fats.
This study was performed to examine the effects of dietary Acanthopanax senticosus (AS) on growth performance, immune organ weights, blood biochemical parameters and the expression of pro-inflammatory cytokines in broiler chicks. A total of 120 4-day-old birds were given a basal diet (CON) or a basal diet supplemented with 0.5% (AS1) or 1.0% (AS2) AS powder until the birds were 35 days of age. There was no difference in body weight, total gain, feed intake or immune organ weights among the treatment groups. However, the feed conversion ratio in the AS2 group was lower (p<0.05) than that in the CON group. Serum biochemical components, including AST (aspartate aminotransferase), ALT (alanine aminotransferase), albumin and total protein, were not affected by the dietary treatments, whereas glucose and triglyceride levels increased (p<0.05) in the AS2 group compared with the CON group. The AS1 group exhibited decreased mRNA expression (p<0.05) of IFN-${\gamma}$ in white blood cells and iNOS in the liver compared with the CON group. The other pro-inflammatory cytokines were unaffected by dietary AS supplementation, although there was a trend towards decreased expression of these genes, including those encoding Il-$1{\beta}$, IL-6 and TNF-${\alpha}$. In conclusion, dietary supplementation with 0.5% AS decreased the expression of several pro-inflammatory cytokines without affecting growth performance, suggesting that this supplement might be applicable as an immunoregulatory feed additive in broiler chicks.
The aim of the study was to investigate the effects of dietary supplementation of zinc (Zn) sources (zinc oxide and Zn-methionine) on performance, organ weights, blood biochemical profiles, and digestive enzymes of the pancreas and small intestine in Korean native chicks (KNC). A total of 144 KNC (n=6) were fed a basal diet (CON, 100 ppm of Zn), a basal diet supplemented with 50 ppm of Zn with ZnO (ZNO), or a basal diet supplemented with 50 ppm of Zn with Zn-methionine (ZMT) for 28 days. There was no significant difference in body weight, gain, feed intake, and feed conversion ratio among the three groups. The relative weights of the liver, spleen, and intestinal mucosa were unaffected by the dietary source of Zn, whereas pancreas weight in the ZNO group decreased (P<0.05) compared with that in the CON and ZMT groups. Blood biochemical components including aspartate aminotransferase, and alanine aminotransferase were unaffected by dietary Zn supplementation. Pancreatic trypsin activity in the ZNO and ZMT groups was significantly (P<0.05) enhanced compared with that in the CON group. However, the activities of ${\alpha}$-amylase and carboxypeptidase A were not altered by dietary Zn supplementation. The activities of maltase and sucrase were unchanged, whereas the activity of leucine aminopeptidase tended (P=0.08) to be increased by dietary Zn supplementation. In conclusion, the supplementation with 50 ppm of ZnO or Zn-methionine resulted in an activation of protein digestive enzymes in the pancreas and small intestine without affecting animal performance in KNC.
