  • This study was designed to investigate the effects of Gleditsiae Spina (GS) on polycystic ovary (PCO) induced by estradiol valerate in female rats. We investigated the effects of GS on changes in body weights and food and water uptake for 5 weeks. In addition, we also examined the effects on ovary weights. Finally, we observed histopathological changes in PCO rats. Treatment with GS did not affect body weights, amount of food and water uptake compared with non-treated control group. Administration group of GS restored body/ovary weight ratio to normal levels, which were lowered by induction of PCO. In histopathological observation, formation of cysts was suppressed in GS group compared with non-treated control group. These results suggest that GS can be used for patients with PCO to prevent formation of cystic follicles and malfunction of ovary.

  • Ginseng total saponins(GS), protopanaxadiol saponins(PD) and protopanaxadiol saponins(PT) antagonized the analgesia in mice induced by morphine. The administrations of 2,4-dihydroxyphenylalanine, and 5-hydroxytryptophan reduced the GS, PD and PT antagonisms of morphine analgesia. Possible mechanisms involved in the antagonistic actions of GS, PD and PT on morphine analgesia were described.

  • Background: Diabetic neuropathy is one of the most devastating ailments of the peripheral nervous system. Neuropathic pain develops in ~30% of diabetics. Here, we examined the suppressive effect of GS-KG9 on neuropathic pain induced by streptozotocin (STZ). Methods: Hyperglycemia was induced by intraperitoneal injection of STZ. Rats showing blood glucose level > 250 mg/dL were divided into five groups, and treatment groups received oral saline containing GS-KG9 (50 mg/kg, 150 mg/kg, or 300 mg/kg) twice daily for 4 wk. The effects of GS-KG9 on pain behavior, microglia activation in the lumbar spinal cord and ventral posterolateral (VPL) nucleus of the thalamus, and c-Fos expression in the dorsal horn of the lumbar spinal cord were examined. Results: The development of neuropathic pain began at Day 5 and peaked at Week 4 after STZ injection. Mechanical and thermal pains were both significantly attenuated in GS-KG9-treated groups from 10 d after STZ injection as compared to those in the STZ control. GS-KG9 also repressed microglia activation in L4 dorsal horn and VPL region of the thalamus. In addition, increase in c-Fos-positive cells within L4 dorsal horn lamina I and II of the STZ control group was markedly alleviated by GS-KG9. Conclusion: These results suggest that GS-KG9 effectively relieves STZ-induced neuropathic pain by inhibiting microglial activation in the spinal cord dorsal horn and VPL region of the thalamus.

  • Type 2 diabetes mellitus is a chronic and hard to control disease. In order to develop the therapeutic agent for type 2 DM, many researchers investigated natural products using an in vitro and in vivo assay. In this study, we tried to explore the anti-diabetic activity and mechanisms of ginsam, which is a vinegar-processed ginseng radix. The db/db mice were randomly divided into four groups. The diabetes control (DC) group was orally administrated with distilled water, ginseng radix (GR) or ginsam (GS) was administrated orally at a dose of 150 mg/kg, and the positive control group was orally injected with metformin (MET) at a dose of 300 mg/kg for 5 weeks in db/db mice and measured body weight and blood glucose level every week. All treatment groups decreased the plasma glucose levels compared with diabetic control and GS group significantly lowered the insulin resistance index. GS group also reduced the plasma lipid levels mainly due to reduce the lipogenesis and increase the lipolysis in the fat tissue. In addition, GS group increased the GLUT4 mRNA expression levels in the fat and muscle tissues by 10 fold probably due to increase a $PPAR_{-\gamma}$ mRNA expression in fat tissue. Taken together, GS showed the anti-hyperglycemic and anti-hyperlipidemic activities and those activities may ascribe to over-expression of GLUT4 mRNA level and decrease the lipogenesis in fat tissue.

  • This study focused on safety aspects surrounding energy consumption in the seawater desalination process in the Daesan Industrial Complex located on the West Sea coast. The safety index for energy consumption was evaluated under different salinities and temperatures of the incoming seawater. Temperature and salinity input data for the 1997-2018 period were obtained from the Marine Environment Information System, and the power required for reverse osmosis (RO) was applied to the program as per the data provided by the RO membrane manufacturer (Q-Plus v3.0). Notably, reasonable energy consumption guidelines were proposed during the design of the desalination facilities; in this regard, the desalination process required approximately 2.10-2.90 kWh/m3 electrical power. Moreover, the energy safety based on 95 % was estimated to be 2.80 kWh/m3 when the desalination facility was operated.

  • The present study was conducted to measure diurnal patterns in the flow of soluble non-ammonia nitrogen (SNAN) fractions in the liquid phase of digesta entering the omasum of cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated cows were fed, in a 4×4 Latin square design, grass-red clover silage alone (GS) or supplemented with (on a DM basis) 6.0kg/d of barley grain, 2.1kg/d of rapeseed meal or 6.0kg/d of barley and 2.1kg/d rapeseed meal. Omasal digesta was taken using an omasal sampling system at 1.5h intervals during a 12h feeding cycle, and SNAN fractions (free AA, peptide and soluble protein) in the omasal digesta were assessed using ninhydrin assay. Dietary supplementation numerically increased the mean flow of SNAN fractions relative to GS diet despite the lack of statistical significance. Diurnal patterns in the flow of peptide entering the omasum during a 12h feeding cycle appeared to be highest immediately after feeding, declined by 10.0h post-feeding and slightly increased thereafter. In SNAN fractions, the flow of peptide was higher for supplemented diets than for GS diet throughout the feeding cycle. Based on the microbial contribution to total SNAN using 15N, diurnal patterns in the flow of dietary SNAN for dietary supplemented diets appeared to be higher compared with GS diets. Present results may conclude that peptide flow is quantitatively the most important N in SNAN fractions and that dietary supplementation can increase peptide flow entering the omasal canal.

  • The biological activities of licorice F1 (Glycyrrhiza glabra ${\times}$ G. uralensis) lines (G) were investigated, revealing strong radical scavenging activity targeting 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl (${\cdot}OH$) radicals. At a concentration of $100{\mu}g/mL$, most of the licorice F1 lines scavenged DPPH and ${\cdot}OH$ by more than 80%. Gs-1, -2, and -6 can be considered good scavengers of DPPH radical and G-7 have higher antioxidant activity against ${\cdot}OH$ radical. In addition, licorice F1 lines exerted effective anti-microbial activities against Escherichia coli (Gs-12, -17, and -18) and Staphylococcus aureus (Gs-3, -4, -5, -21, and -26). Moreover, Gs-2, - 20, -31, and -32 effectively inhibited the growth of Helicobacter pylori. Among licorice F1 lines, Gs-25 exhibited high anti-inflammatory effects on nitric oxide produced by lipopolysaccharide- and interferon-${\gamma}$-activated RAW 264.7 cells. Furthermore, Gs-1, -12, and -20 inhibited the growth of AGS human gastric adenocarcinoma cells by more than 60% at a concentration of $100{\mu}g/mL$ and Gs-5, -11, -19, and -32 showed inhibitory effects against rat lens aldose reductase ($IC_{50}$ values, 1.69, 6.07, 6.12, and $4.54{\mu}g/mL$, respectively). The total content of glycyrrhizin (1), glycyrrhetinic acid (2), glabridin (3), and isoliquiritigenin (4) in licorice F1 lines was high in Gs-11, -15, and -30. The present study therefore indicated that Gs-2, -26, -31, and -32 of licorice F1 possessing strong anti-oxidative, anti-microbial, anti-inflammatory, anti-cancer, and aldose reductase inhibitory effects may be used as a possible source material for natural health supplements in the future.

  • This study was conducted to examine the effects of Glycine soja (GS) supplementation on the quality of corn silage. Corn silage was used in a $3{\times}2$ factorial arrangements with respective factors being addition of GS (0, 10, and 20%) and without or with Lacobacillus plantarum as lactic acid bacteria, and were stored for 40 days at a room temperature ($20-25^{\circ}C$). Corn silage with supplemented 20% GS increased (p<0.05) crude protein contents compared with that in corn silage with supplemented 0 and 10% GS, however crude fat, NDF, and starch concentrations was not affected (p<0.05) by addition of GS. Furthermore, the interaction was found (p<0.05) between corn silage with supplemented 20% GS and the addition of lactic acid in butyric acid. Silage pH was increased while GS supplementation increased. Corn silage with supplemented 20% GS increased (p<0.05) glucose and fructose concentrations. The results of current study indicate that corn silage with supplemented 20% GS could be used as a useful strategy to improve corn silage with increased crude protein contents along with sucrose, glucose and fructose concentrations.

  • Mutans streptococci, especially S. mutans and S. sobrinus strongly implicated in pathogenesis of dental caries, the major cause of tooth loss in children. Use of an antibacterial agent controlling dental caries has been rationalized. The present study was performed to observe the antibacterial effect of inorganic polyphosphates (polyP) on S. mutans and S. sobrinus. S. mutans GS5 and S. sobrinus 6715 were grown in brain-heart infusion broth with or without polyP. Minimal inhibitory concentration (MIC) of polyP for S. mutans GS5 was determined to be 0.08% and that for S. sobrius 6715 was 0.17%. PolyP 15 added to the growing culture of S. mutans GS5 and S. sobrinus 6715 at their exponential phase was as effective in inhibiting the growth of S. mutans GS5 and S. sobrinus 6715 as polyP added at the very beginning of the culture. More than 85% of the cells lost their viability determined by viable cell count when polyP 15 was added to the culture of growing S. mutans GS5 at MIC, suggesting that polyP 15 has bacterial effect on the bacterium. And more than 99.9% of the cells lost their viability determined by viable cell count when polyP 15 was added to the culture of growing S. sobrinus 6715 at MIC, suggesting that polyP 15 has bacterial effect on the bacterium. Intracellular nucleotide release from S. mutans CS5 and S. sobrinus 6715 was increased in the presence of polyP 15 for 5h but was not really reversed by the addition of divalent cations like $Ca^{++}\;and\;Mg^{++}$. The majority of the cells appeared to be atypical in their shape, demonstrating accumulation of highly electron-dense granules and ghost cells. The overall results suggest that polyP have a strong bactericidal activity against S. mutans and S. sobrinus in which lysis in relation to chelation may not play the major role but unknown mechanism that possibly affects the viability of the bacterium may be involved. PolyP may be used as an agent for prevention of dental caries.

  • The aim of this study was to evaluate the effect of replacing corn grain for sugar cane molasses (MO) or glucose syrup (GS) in the starter concentrate on performance and metabolism of dairy calves. Thirty-six individually housed Holstein male calves were blocked according to weight and date of birth and assigned to one of the starter feed treatments, during an 8 week study: i) starter containing 65% corn with no MO or GS (0MO); ii) starter containing 60% corn and 5% MO (5MO); iii) starter containing 55% corn and 10% MO (10MO); and iv) starter containing 60% corn and 5% GS (5GS). Animals received 4 L of milk replacer daily (20 crude protein, 16 ether extract, 12.5% solids), divided in two meals (0700 and 1700 h). Starter and water were provided ad libitum. Starter intake and fecal score were monitored daily until animals were eight weeks old. Body weight and measurements (withers height, hip width and heart girth) were measured weekly before the morning feeding. From the second week of age, blood samples were collected weekly, 2 h after the morning feeding, for glucose, ${\beta}$-hydroxybutyrate and lactate determination. Ruminal fluid was collected at 4, 6, and 8 weeks of age using an oro-ruminal probe and a suction pump for determination of pH and short-chain fatty acids (SCFA). At the end of the eighth week, animals were harvested to evaluate development of the proximal digestive tract. The composition of the starter did not affect (p>0.05) concentrate intake, weight gain, fecal score, blood parameters, and rumen development. However, treatment 5MO showed higher (p<0.05) total concentration of SCFAs, acetate and propionate than 0MO, and these treatments did not differ from 10MO and 5GS (p>0.05). Thus, it can be concluded that the replacement of corn by 5% or 10% sugar cane molasses or 5% GS on starter concentrate did not impact performance, however it has some positive effects on rumen fermentation which may be beneficial for calves with a developing rumen.
