This study aimed to investigate the effect of sunflower seeds, either as whole or as oil, on rumen fermentation, milk production, milk composition and fatty acids profile in dairy goats. Fifteen lactating Damascus goats were divided randomly into three groups (n = 5) fed a basal diet of concentrate feed mixture and fresh Trifolium alexandrinum at 50:50 on dry matter basis (Control) in addition to 50 g/head/d sunflower seeds whole (SS) or 20 mL/head/d sunflower seeds oil (SO) in a complete randomized design. Milk was sampled every two weeks during 90 days of experimental period for chemical analysis and rumen was sampled at 30, 60, and 90 days of the experiment for ruminal pH, volatile fatty acids (tVFA), and ammonia-N determination. Addition of SO decreased (p = 0.017) ruminal pH, whereas SO and SS increased tVFA (p<0.001) and acetate (p = 0.034) concentrations. Serum glucose increased (p = 0.013) in SO and SS goats vs Control. The SO and SS treated goats had improved milk yield (p = 0.007) and milk fat content (p = 0.002). Moreover, SO increased milk lactose content (p = 0.048) and feed efficiency (p = 0.046) compared to Control. Both of SS and SO increased (p<0.05) milk unsaturated fatty acids content specially conjugated linolenic acid (CLA) vs Control. Addition of SS and SO increased (p = 0. 021) C18:3N3 fatty acid compared to Control diet. Data suggested that addition of either SS or SO to lactating goats ration had beneficial effects on milk yield and milk composition with enhancing milk content of healthy fatty acids (CLA and omega 3), without detrimental effects on animal performance.

The liver is one of the principal organs involved in glucose metabolism. Diabetes mellitus(DM) commonly develops in patients with liver cirrhosis as a result of hepatocyte dysfunction. Hepatic encephalopathy(HE) is a major neuropsychiatric complication of liver cirrhosis. HE develops frequently in advanced stage of liver cirrhosis due to portal hypertension. We experienced a case of liver cirrhosis with DM and HE in 67 years old male patient. The patient's symptoms were lethargy, general malaise, asterixis, dizziness, and heavy headedness. Hwangryunjihwang-tang, Saengkankunbi-tang, Injinchija-tang and Injinho-tang were prescribed to the patient. Finally, the symptoms had been improved, however significant change was not observed from serum ammonia, fasting blood sugar and postparandial blood sugar. So we hope that this case report will be helpful in treating patient of liver cirrhosis.

The fruit, leaves, and roots of Elaeagnus multiflora Thunb. have been used in traditional Chinese medicine to treat cough, diarrhea, and itching. However, the anti-fatigue effects of E. multiflora fruit (EMF) extract have not been studied in detail. The aim of this study was to examine the effect of EMF on fatigue and exercise performance in BALB/c mice. EMF was orally administered to mice at four doses (10, 50, 100, and 200 mg/kg/day) for 2 weeks. The anti-fatigue activity was evaluated by determining the exhaustive swimming time. Blood lactate and glucose levels and serum lactate levels after a 10 min swimming time, as well as ammonia, creatine kinase (CK), blood urea nitrogen (BUN), lactate dehydrogenase (LDH), and glycogen contents after exhaustive swimming time were measured. The exhaustive swimming time of the EMF 200 group was significantly increased (p <0.01). The EMF groups showed significantly low levels of CK, BUN, LDH, and lactate compared with the control group (p <0.05). Increased liver glycogen was observed in the EMF 200 group (p <0.05). These results suggest that EMF can be utilized as an efficacious natural resource for its anti-fatigue effects.

Twelve epoxy and hydroxydiosgenin derivatives (DI-1${\sim}$DI-12) were synthesized from diosgenin (25(R)-5-spirosten-3${\beta}$-ol). Diosgenin was epoxidized with m-chloroperoxybenzoic acid (mCPBA) to oxidize 25(R)-4${\alpha}$,5${\alpha}$-epoxyspirostane (DI-1). Diosgenin was reacted with DDQ to form 25(R)-1,4,6-spirostatrien-3-one (DI-2), which was treated with 30% H$_2$O$_2$ to give 25(R)-1${\alpha}$,2${\alpha}$-epoxy-4,6-spirostadien-3-one (DI-3) and treated with mCPBA to form 25(R)-6${\alpha}$,7${\alpha}$-epoxy-1,4-spirostadien-3-one (DI-7), respectively. DI-3 was reduced with NaBH$_4$ to afford 25(R) -1${\alpha}$,2 ${\alpha}$-epoxy-4,6-spirostadien-3${\beta}$-ol(DI-4) and reacted with Li metal in absolute ethanol to form 25(R)-2-ethoxy-1,4,6-spirostatrien-3-one (DI-5). DI-7 was reduced with NaBH$_4$ to produce 25(R)-3${\beta}$,7${\alpha}$-dihydroxy-4-spirostene (DI-8) and treated with Li metal in liquid ammonia to produce 25(R)-7${\alpha}$-hydroxy-4-spirosten-3-one (DI-9). DI-2 was reduced with NaBH$_4$ to form 25(R) -4,6-spirestadien-3${\beta}$-ol(DI-10), which was stirred with 30% H$_2$O$_2$ to synthesize 25(R)-4,6-spirostadien-3-one (DI-11) and reacted with mCPBA to give 25(R)-4${\beta}$,5${\beta}$ -epoxy-6-spirosten-3${\beta}$-ol (DI-12), respectively. The antinociceptive effects of synthesiz ed compounds were measured by hot plate method and compound DI-7 signifcantly exhibited antinociceptive effect. DI-2 decreased the serum triglyceride and total cholesterol levels in poloxamer P-407 injected rat.

Purpose: Owing to the increased agricultural use of the herbicide glufosinate ammonium (GLA), the incidence of GLA poisoning has recently increased. Therefore, we investigated the possible predictive factors associated with severe complications following GLA poisoning. Methods: A retrospective analysis of medical records was conducted based on 76 patients who had visited our regional emergency medical center with GLA poisoning from 2006 to 2017. Severe complications were defined as respiratory failure requiring intubation, systolic blood pressure less than 90 mmHg, Glasgow Coma Scale (GCS) less than 8, and presence of seizure. Results: Age, ingested amount and ingested amount per weight were significantly greater in the severe group (p<0.001). PSS grade 2 or higher was more common in the severe group (p<0.001), and In addition, the APACHE II score was significantly higher in the severe group (p<0.001), as were the SOFA scores (p=0.002). Serum ammonia levels were significantly higher in the severe group (p=0.007), while MDRD-GFR was smaller in the severe group (p=0.002). The spot urine protein levels were significantly higher in the severe group (p=0.005), as was the urine protein to creatinine ratio (p=0.001). Upon multivariate analysis, the amount ingested per weight and PSS grade 2 or higher were identified as significant predictors. Conclusion: Our study showed that MDRD-GFR was significantly lower in the severe group after GLA poisoning. PSS grade 2 or higher and ingested amount per weight may be useful to evaluate the severity of complications after GLA poisoning.

Curcumin ($C_{21}H_{20}O_6$) is a hydrophobic polyphenol found in turmeric. Although curcumin has been used as a natural medicine, its major limitation is related to poor absorption from the gut. Therefore, we developed a method for preparation of Curcumin Nanospheres (CN) to improve the aqueous-phase solubility of curcumin and investigate the functional role of CN in promoting feed efficiency and odor reduction in mice. CN showed inhibitory effects on actate dehydrogenase (LDH) cytotoxicity induced by ecotoxic substance toluene in gut epithelial HCT116 cells. In addition, the weights of internal organs (liver, heart, kidneys, and spleen) and the levels of serum Glutamate Oxaloacetate Transaminase (GOT), Glutamate Pyruvate Transaminase (GPT), and LDH did not show significant differences between mice administered oral CN for two weeks and compared to the control group. Interestingly, CN not only reduced hydrogen sulfide ($H_2S$) and ammonia ($NH_3$) levels and fecal odor, but also improved feed efficiency in mice. These results demonstrate that oral nano-delivery of anti-ecotoxicological CN is a functional system to deliver curcumin to the gut to improve feed efficiency and reduce fecal odor in mice.

Objective : In modern society, liver diseases such as liver fibrosis are on the rise as inflammation and wound healing processes of the liver are repeated due to factors such as drinking, smoking, and stress. This study was conducted to evaluate the effect of Saenggangeonbi-tang (SGGBT) on thioacetamide (TAA)-induced liver fibrosis. Methods : The mice were divided into 4 groups for examination (n=6): Normal group (Nor), distilled water-treated liver fibrosis mice (Con), silymarin 50 mg/kg-treated liver fibrosis mice (Sily), SGGBT 200 mg/kg-treated liver fibrosis mice (S200). Liver fibrosis was established in the mice via TAA for 8 weeks (1 week 100 mg/kg, 2,3 weeks 200 mg/kg, 4-8 weeks 400 mg/kg, three times a week, intraperitoneal injection) and they were administered silymarin and SGGBT (every day, oral administration) with the TAA. Results : SGGBT significantly decreased the levels of aspartate aminotransferase, alanine aminotransferanse, ammonia, and myeloperoxidase in serum increased by liver fibrosis. As a result of confirming H&E and MT staining, it was confirmed that SGGBT reduced damage and inflammatory cell infiltration in liver tissue, and alleviated changes in collagen fiber deposition and histological fibrosis. Also, it was confirmed through PAS staining that it reduced glycogen deposition in liver tissue. In addition, SGGBT significantly decreased the NADPH oxidases as well as significantly modulated the expression of MMP-2 and TIMP-2. Conclusions : These results suggest that SGGBT regulates the expression of MMP/TIMP protein through inhibition of oxidative stress and alleviates liver fibrosis by reducing collagen and glycogen deposition in liver tissue.

Objective : This study examined the effects of yaksun recipe on the anti-fatigue and endurance enhancement properties in the forced swimming test (FST). Methods : The treatment groups were divided randomly into three groups: water-treated FST (control), 200 mg/kg of red ginseng-treated FST (RG200), 200 mg/kg of water extract of yaksun recipe-treated FST (YS200). After FST, an autopsy was performed, and the tissue and serum were collected. Results : The swimming exhaustion time in the RG200 and YG200 groups were significantly increased compared to the control group. The YG200 group fatigue indicators, D-Lactate, LDH(lactate dehydrogenase), creatine kinase, and ammonia content, significantly decreased compared to the control group. In addition, liver glycogen content significantly increased in the YG200 and tended to increase in RG200. Likewise, the glucose contents were significantly increased compared to the control group. The muscle damage indicators GPT (glutamic pyruvic transaminase) and BUN (blood urea nitrogen), a protein metabolite, in the YG200 group significantly decreased compared to the control group. Furthermore the concentration of liver lipid peroxidation, MDA(malondialdehyde) levels significantly decreased in the RG200 and YG200 compared to control group. Conclusions : These results suggest that YG200 can increase the endurance exercise capacity by decreasing the fatigue indicators, saving glycogen, and elevating the antioxidant defense system.
