Effect of combined preparation (DWP715) containing Alaska pollack extract, maltol, ascorbic acid and nicotinamide on decreasing of blood alcohol was evaluated in human blood. Treatment of DWP715 prior to administration of 25% alcohol (100 mL) decreased alcohol concentration in blood and showed significant difference after 2 hours. The pharmacokinetic parameters such as area under the concentration-time curve (AUC), $C_{max},\;T_{max}\;and\;T_{1/2}$ were also decreased and delayed when compared with control values. Effects of DWP715 on anti-fatigue and anti-oxidation activities were also studied in the restraint stress model using various parameters (GOT, GPT, LDH values and organ weights) on mild condition and examined through the content of lipid peroxide induced by 2% $CCl_4$ in mouse livers. While GPT level, thymus and adrenal weight were not influenced by DWP715 dosing, LDH, GOT level and spleen weight used as a parameter against fatigue and stress states were recovered almost to the nomal level. Furthermore, lipid peroxidation due to $CCl_4$ was significantly inhibited by DWP715 treatment. These results suggest that DWP715 seems to metabolize the blood alcohol rapidly and to restore the damaged liver and fatigue conditions which was caused by alcohol metabolism to normal condition.

The aims of this study were to investigate the antioxidative and antitumor effects of crude polysaccharide fraction from Pleurtus eryngii (CPPE). CPPE inhibited autoxidation of linoleic acid at 1,000 $\mu$g/mL concentration, and the inhibitory rates of lipid peroxidation in rat liver microsome were 5.28, 9.40, and 32.5% at 10, 100, and 1,000 $\mu$g/mL concentrations, respectively. After treatment with CPPE for 72 hours, the inhibitory rates against MCF-7, A549 and AGS cell lines showed 42.3, 33.4 and 26.7% at concentration of 1,000 $\mu$g/mL, respectively. Results of CPPE treatment at 100 and 300 mg/kg/day for 7 days in sarcoma-180 bearing-mice showed survival rates of 70 and 90%, respectively. Body weights of mice treated with CPPE were significantly decreased when compared with the control.

The effects of feeding indole, indole-3-carbinol and benzofuran (all at 5 mmole/kg body wt./day) on various hepatic microsomal and cytosolic enzyme activities involved in xenobiotic metabolism have been compared. Benzofuran was found to elevate the activities of many enzymes both in microsomes (e.g., aniline hydroxylase, 7-ethoxycoumarin O-deethylase, p-nitrophenol UDPGA-transferase and epoxide hydrolase) and in cytosol (e.g., glutathione reductase, glutathione S-transferase, NADH:quinone reductase and UDP-glucose dehydrogenase). The structures of indole and indole-3-carbinol are similar to benzofuran except for the substitution of nitrogen with oxygen atom within the furan ring. Results showed that the activities of UDPGA-transferase and NADH:quinone reductase were not elevated by these indole compounds. While the chemical structure of these two indole compounds are identical except for the presence of the carbinol (methanol) group in indole-3-carbinol, there were marked differences in the types and activities of microsomal enzymes that were enhanced. Among the microsomal enzyme activities determined, indole elevated only the NADPH:cytochrome c reductase, while indole-3-carbinol increased several mixed function oxidase and particularly the epoxide hydrolase activities. Based on the chemical structures of tested compounds and the observed results, possible explanations for the mechanisms involved in elevating epoxide hydrolase activity by benzofuran and indole-3-carbinol are discussed.

Objectives : This study was designed to investigate anti-obesity effects of DF in a ob/ob mouse model. Methods : Fifteen-week-old ob/ob mice were divided into four groups: a normal lean group given a standard diet, an ob/ob control group given a standard diet, and DF(1) and DF(2) groups given a standard diet with DF(1) (300 mg/kg), and DF(2) (600 mg/kg), respectively. After 10 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, fat weight and histology were examined. Results : Body weight gain and fat mass were significantly decreased in DF(1) and DF(2) groups compared with control. The extent of decreases was eminent in DF(2) group. Feeding efficiency ratio were significantly decreased in DF(2) group compared with control. Consistent with their effects on body weight gain and fat mass, circulating concentrations of LDL, total cholesterol, free fatty acid, and insulin were decreased in DF(2) group compared with control. The size of adipocytes were significantly decreased by DF(2) compared with control. Consistent with their effects on body weight gain, hepatic lipid accumulation and liver weights were reduced in DF compared with control. Conclusions : In conclusion, these results suggest that DF not only decrease feeding efficiency ratio, and blood anti-obesity biomarkers, but also reduce fat mass, contributing to the improvement of obesity. DF also inhibits hepatic lipid accumulation.

TIAF1 is a TGF-${\beta}$1-induced anti-apoptotic factor that plays a critical role in blocking TNF (tumor necrosis factor) cytotoxicity in mouse fibroblasts and participates in TGF-${\beta}$-mediated growth regulation. In this study, we obtained the full-length cDNA sequence of the porcine TIAF1 gene. Real-time PCR further revealed that the TIAF1 gene was expressed at the highest level in liver and kidney with prominent expressions detected in uterus, and lower levels detected in heart, spleen, lung, stomach, small intestine, skeletal muscle and fat of Large White pigs. Sequence analysis indicated that a 6 base-pair deletion mutation existed in the exon of the TIAF1 gene between Meishan and Large White pigs. This mutation induced deletion of Gln and Val amino acids. PCR-RFLP was used to detect the polymorphism in 394 pigs of a "Large White${\times}$Meishan" $F_{2}$ resource population and four purebred pig populations. The frequencies of the A allele (with a 6 bp deletion) were dominant in Chinese Meishan and Bamei pigs, and the frequencies of the B allele (no 6 bp deletion) were dominant in Large White and Landrace pigs. Association analyses revealed that the deletion mutation had highly significant associations (p<0.01) with meat marbling score of the thorax-waist longissimus dorsi (LD) muscle (MM1) and intramuscular fat percentage (IMF), and significant associations (p<0.05) with carcass length (CL). The results presented here supply evidence that the 6 bp deletion mutation in the TIAF1 gene affects porcine meat quality and provides useful information for further porcine breeding.

The chemical formula of indapamide is 3-(aminosulfonyl)-4-chloro-N-(2,3-dihydro-2-methyl-1H-indol-l-yl)-benzamide, Indapamide is an oral antipertensive diuretic agent indicated for the treatment of hypertensive and edema. Indapamide inhibits carbonic anhydrase enzyme. Transdermal drug delivery systems, as compared to their corresponding classical oral or injectable dosage form counterparts, offer many advantages. The most important advantages are improved systemic bioavailability of the pharmaceutical active ingredients (PAI), because the first-pass metabolism by the liver and digestive system are avoided; and the controlled, constant drug delivery profile (that is, controlled zero-order absorption). Also of importance is the reduced dose frequency compared to the conventional oral dosage forms (that is, once-a-day, twice-a-week or once-a-week). Other benefits include longer duration of therapeutic action from a single application, and reversible action. For example, patches can be removed to reverse any adverse effects that may be caused by overdosing. In order to evaluate the effects of vehicles and penetration enhancers on skin permeation of Indapamide, the skin permeation rates of Indapamide from vehicles of different composition were determined using Franz cells fitted with excised hairless skins. Solubility of Indapamide in various solvents was investigated to select a vehicle suitable for the percutaneous absorption of Indapamide, The solvents used were Tween80, Tween20, Labrasol, Lauroglycol90 (LG90) and Peceol. Lauroglycol90 increase the permeability of indapamide approximately 3.75-fold compared with the control. Tween80, Tween20, Labrasol, Lauroglycol90 (LG90) and Peceol showed flux of $0.06ug/cm^2/hr,\;0.4ug/cm^2/hr,\;0.21ug/cm^2/hr,\;0.72ug/cm^2/hr,\;0.29ug/cm^2/hr$, respectively.

Sodium butyrate (SB) has various metabolic actions. However, its effect on dipeptidyl peptidase 4 (DPP-4) needs to be studied further. We aimed to evaluate the metabolic actions of SB, considering its physiologically relevant concentration. We evaluated the effect of SB on regulation of DPP-4 and its other metabolic actions, both in vitro (HepG2 cells and mouse mesangial cells) and in vivo (high fat diet [HFD]-induced obese mice). Ten-week HFD-induced obese C57BL/6J mice were subjected to SB treatment by adding SB to HFD which was maintained for an additional 16 weeks. In HepG2 cells, SB suppressed DPP-4 activity and expression at sub-molar concentrations, whereas it increased DPP-4 activity at a concentration of $1,000{\mu}M$. In HFD-induced obese mice, SB decreased blood glucose, serum levels of insulin and $IL-1{\beta}$, and DPP-4 activity, and suppressed the increase in body weight. On the contrary, various tissues including liver, kidney, and peripheral blood cells showed variable responses of DPP-4 to SB. Especially in the kidney, although DPP-4 activity was decreased by SB in HFD-induced obese mice, it caused an increase in mRNA expression of $TNF-{\alpha}$, IL-6, and $IL-1{\beta}$. The pro-inflammatory actions of SB in the kidney of HFD-induced obese mice were recapitulated by cultured mesangial cell experiments, in which SB stimulated the secretion of several cytokines from cells. Our results showed that SB has differential actions according to its treatment dose and the type of cells and tissues. Thus, further studies are required to evaluate its therapeutic relevance in metabolic diseases including diabetes and obesity.

The purpose of this study was to determine the effects of dried Dendropanax morbifera leaf extracts on lipid profiles of mice fed a high-fat and -cholesterol diet (HFCD). ICR mice were divided into six groups based on mice fed AIN-93G diet (Normal), HFCD (Control), HFCD+100 mg/kg/d of D. morbifera leaf aqueous extract (DA-100), HFCD+200 mg/kg/d of D. morbifera leaf aqueous extract (DA-200), HFCD+100 mg/kg/d of D. morbifera leaf ethanol extract (DE-100), or HFCD+200 mg/kg/d of D. morbifera leaf ethanol extract (DE-200) for 7 weeks. The final body weights of mice fed D. morbifera extracts were all lower than those of the control group. Mice treated with D. morbifera extracts showed significantly reduced plasma and hepatic triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol levels, along with increased plasma high-density lipoprotein cholesterol level. Fecal TG level was higher in DE-100 and DE-200 groups and TC level was significantly higher in the DA-200 and DE-200 groups. Relative liver weight, spleen weight, and testicle fat weight in mice treated with D. morbifera were reduced compared to the control group. Plasma insulin, aspartate transaminase, and alanine transaminase levels of experimental groups were also lower than those of the control group. All mice treated with D. morbifera extracts had lower malondialdehyde (MDA) content and higher superoxide dismutase (SOD) activity than the control group. Particularly MDA levels of the DA-200 and DE-200 groups and SOD levels of the DE-200 group were identical to levels of the normal group. These results suggest that D. morbifera extracts have lipid improvement effects in mice fed a HFCD.

This study were performed to investigate the effect of Bisphenol A(BPA) administration on semen characteristic and body or organ weight in mice. In BPA administration for 15 days or 30 days, sperm concentration and viability were lower in group treated with BPA than in control group. The proportion of sperm abnormality were significantly(P＜0.05) increased in groups administrated with BPA for 15 or 30 days than in control group. The administration of BPA in mice didn't affect the body and reproductive organ weight such as testis, epididymis, vasicular gland and coagulatin gland. The spleen weight were significantly affect, but liver and kidney weight were not affect in BPA administration groups for 15 days or 30 days This studies indicate that the short or long term BPA administration in mice were noxious effects on the semen characteristics and organ weight, but didn't affect body weight and reproductive organs.
