  • n-Butanol extracts from Phellodendron amurense have about 50% inhibitory activity against hyaluronidase. The anti-inflammatory compound was isolated from P. amurense by Sephadex LH-20 and MCI-gel CHP-20 column chromatography with gradient elution. As a the result, its structure was identified as Jatrorrhizine by the interpretation of spectroscopic analyses including $^1H$- and $^{13}C$-NMR. In anti-inflammatory activity, the expression of nitric oxide (NO) was inhibited as above 60% at 100 ${\mu}g/mL$ concentration of extracts and then purified Jatrorrhizine from P. amurense. The inhibitory activities against the expression of inducible NO syntase (iNOS) and cyclooxygenase-2 (COX-2) were 45% and 29%. It seems that the extracts and purified Jatrorrhizine from P. amurense were expected anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated Raw264.7 cells.

  • Conjugated linoleic acid (CLA) has been shown to have a range of biological activities, including anti-carcinogenic, anti-atherosclerotic, anti-adipogenic and anti-diabetogenic effects. Recent reports also showed that CLA has free radical scavenging capacity, which may have health benefits for human beings. The current study was performed to investigate the effect of structured lipid (SL)-containing CLA on plasma lipids and hepatic antioxidant enzyme activity. Sprague-Dawley mts were fed 5% and 10% SL-containing normal diet for 6 wks and these groups were compared to rats fed 5% and 10% corn oil. In plasma lipids, total-cholesterol was not affected by fat source or dietary fat level while triglyceride level decreased significantly in groups fed 10% fat diet compared to the other groups. Plasma thiobarbituric acid reactive substances (TBARS) level decreased significantly in the S5 and S10 groups compared to the C5 and C10 groups, although hepatic TBARS level was not altered by fat source. On the other hand, in terms of hepatic antioxidant enzyme activity, superoxide dismutase activity increased in the S10 group, whereas catalase activity decreased in the S10 group. Glutathione peroxidase activity decreased significantly in the SL groups compared to the C5 group. Glutathione reductase activity increased and glucose-6-phosphate dehydrogenase activity decreased in the C10 group compared to the C5 and C5 groups. In conclusion, the free radical scavenging activity of CLA seemed to suppress oxidative stress, which reduced lipid peroxidation resulting in lower hepatic antioxidant enzyme activity.

  • Antioxidant activities of blackberry juice and aronia juice were enhanced when fermentation was performed by acetic acid bacteria. Acetobacter pasteurianus exhibited 19.84% improvement of antioxidant activity (from $198.12{\pm}2.03$ to $237.42{\pm}7.32{\mu}mol\;TE/g$) after 12 h fermentation of blackberry juice among four acetic acid bacteria. And A. pasteurianus sub sp. Pasteurianus exhibited 9.62% improvement of antioxidant activity (from $204.25{\pm}3.98$ to $223.89{\pm}5.52{\mu}mol\;TE/g$) after 12 h fermentation of aronia juice. Metabolites of blackberry juice were analyzed to investigate the enhancement of antioxidant activity before and after fermentation. As results, Quercetin 7-(rhamnosylglucoside), nicotinic acid adenine dinucleotide, and quercetin 3-O-(6"-acetyl-glucoside) were significantly increased after fermentation by A. pasteurianus.

  • In the present study, we enhanced the phenolic content of 70% ethanol extracts of Spirogyra sp. (SPE, $260.47{\pm}5.21$ gallic acid equivalent $[GAE]mg\;g^{-1}$), 2.97 times to $774.24{\pm}2.61GAE\;mg\;g^{-1}$ in the ethyl acetate fraction of SPE (SPEE). SPEE was evaluated for its antiradical activity in online high-performance liquid chromatography-ABTS analysis, and the peaks with the highest antiradical activities were identified as gallic acid derivatives containing gallic acid, methyl gallate, and ethyl gallate. Isolation of ethyl gallate from Spirogyra sp. was performed for the first time in this study. In ultraviolet B (UVB)-irradiated keratinocytes (HaCaT cells), SPEE improved cell viability by 8.22%, and 23.33% and reduced accumulation of cells in the sub-$G_1$ phase by 20.53%, and 32.11% at the concentrations of 50 and $100{\mu}g\;mL^{-1}$, respectively. Furthermore, SPEE (50 and $100{\mu}g\;mL^{-1}$) reduced reactive oxygen species generation in UVB-irradiated zebrafish by 66.67% and 77.78%. This study suggests a protective activity of gallic acid and its derivatives from Spirogyra sp. against UVB-induced stress responses in both in vitro and in vivo models, suggesting a potential use of SPEE in photoprotection.

  • Hepatic fibrosis is one of chronic liver diseases which spread in worldwide and it has high risk to turn advanced cirrhosis and hepatocellualr carcinoma. Brassica family has been produced for commercial purpose and in Korea Brassica rapa (Turnip) is cultivated in Ganghwa County, Gyeonggi-do Korea and used for making Kimchi. Recently pharmacological effects of turnip have been known; diabete mellitus modulation, alcohol oxidization, and fibrosis inhibition. In previous study we found antifibrogenic effect of turnip water extract and in this study we made turnip nanoparticle to promote turnip delivery into liver. At the same time we assessed the biological safety of turnip nanoparticle. Thioacetamide (TAA) induced hepatic nodular formation and fibrosis (mean of fibrosis score: 4). However, 1% turnip nanoparticle inhibited TAA-induced hepatic nodular formation and fibrosis (mean of fibrosis score: 2-3). Activities of serum enzymes (aspartic acid transaminase (AST), alanine transaminase (ALT), and total bilirubin (T-Bil)), complete blood count (CBC), and the appearance of organs were not different from control and 1% turnip nanoparticle treatment. Conclusively 1% turnip nanoparticle significantly reduced TAA-induced hepatic fibrosis and was safe in 7-weeks feeding.

  • Purpose: This study examined the effects of the right or left knee lift during push up plus in the quadruped position on the serratus anterior (SA) muscle activity. Methods: Twenty-one subjects (male 11, female 10) performed the quadruped position on push up plus. The muscle activities of the lower trapezius (LT), SA, and upper trapezius (UT) were measured by surface electromyography. Repeated measurements of one-way ANOVA were performed for statistical analysis of the data, and the criterion for statistical significance was set to p<0.05 and comparative analysis of the UT and SA ratio using a Paired t-test. Results: The right SA increased the muscle activity of the right knee lift during quadruped position push up plus (p<0.05). In particular, the right SA muscle activity was higher than the left. In addition, comparative analysis of the UT and SA ratio to the right knee lift during quadruped position push up plus was performed (p<0.05). The right was found to be a significant statistic compared to the left, but the left SA increased the muscle activity of the left knee lift during quadruped position push up plus (p<0.05). The left SA muscle activity was higher than right. In addition, comparative analysis of UT and SA ratio to the left knee lift during quadruped position push up plus was performed (p<0.05). The left was found to be a significance statistic than the right. In addition, the interaction effect between the groups showed significant differences (p<0.05). Conclusion: Knee lift during push up plus is recommended for the selective activation of a research exercise protocol of one side of the serratus anterior.
