  • Hair loss affects both men and women of all ages and often significantly affects social and psychologic health. Recent therapeutic approach for hair loss such as finasteride and minoxidil focused on regulation of hormonal system blood flow. However, long-term use of these drugs caused adverse effects. To develop herbal medicine for therapeutic effect on hair growth, here we screened the 10 medicinal herbs (Red ginseng, Licorice, Ulmus, Barberry root, Lycium root, Rehmanniae radix crudus, Sophora root, Sweet flag, Polygala root, Achyranthes) based on oriental medicine literature. We measured cytotoxicity, anti-oxidant activity, and $5-{\alpha}$ reductase inhibitory effect of the herbal medicine on human dermal papilla (DP) cells to investigate therapeutic effect of the herbal medicine. Treatment of the 1% herbal medicine did not show any cytotoxic effects, and cell growth was increased by treatment of the 0.1% herbal medicine. In addition, the herbal medicine showed stronger antioxidant activity than resveratrol and comparable inhibitory activity of $5-{\alpha}$ reductase with finasteride. Furthermore, when applied to in vivo mouse model, we also observed increases in the number and length of hair of the herbal medicine-treated group. These results suggest that the herbal medicine promotes hair growth by its antioxidant activity and inhibitory activity of $5-{\alpha}$ reductase and might therefore be a promising hair growth-promoting agent.

  • Positive effect of multiple-PGPR (Plan Growth Promoting Rhizobacteria), isolated from heavy metal contaminated soil, on the germination of Barnyard grass (Echinochloa crus-galli var. frumentacea) was quantitatively estimated in 5 heavy metal (Cd, As, Ni, Cu, and Pb) contaminated liquid medium. The $EC_{50}$ value for respective heavy metal was estimated by TSK (Trimmed Speraman-Karber) model based on germination rate. The results showed overall increase in $EC_{50}$ with PGPR inoculation. The $EC_{50}$ value increased 1.4% from 96.0 mg/L (control) to 97.4 mg/L (PGPR-treated) in As contaminated medium. In Ni contaminated medium, the $EC_{50}$ value increased 31.9% from 148.0 mg/L (control) to 195.2 mg/L (PGPR-treated), while the $EC_{50}$ showed 4.8% increase from 63.4 mg/L (control) to 66.5 mg/L (PGPR-treated) in Cu medium. Overall seedling growth was stronger in the PGPR treated seeds than that in the control, but positive effect on seedling growth was not conspicuous. At effective concentration of 100 mg/L, the average seedling length of the PGPR treatment in As, Cd, Cu, and Ni medium, respectively, was 1.13, 0.14, 0.40, and 0.06 cm longer than that in the control. However, the increase of seedling growth was statistically insignificant (p < 0.05). These results suggest that inoculation of the isolated-PGPR exerts positive effects on seed germination by reducing heavy metal toxicity and can be an effective tool for application of phytoremediation on heavy metal contaminated soils.

  • We isolated nine endophytic fungi from the roots of salt-stressed soybean cultivar Daewonkong and screened them for growth-promoting secondary metabolites. Of all fungal isolates, P-4-3 induced maximum growth promotion of waito-c rice and soybean. Analysis of the culture filtrate of P-4-3 showed the presence of physiologically active gibberellins $GA_1$, $GA_3$, $GA_4$, and $GA_7$, along with physiologically inactive $GA_{15}$ and $GA_{24}$. The plant growth promotion and gibberellin-producing capacity of P-4-3 was much higher than wild-type Gibberella fujikuroi, which was taken as the control during the present study. The fungal isolate P-4-3 was identified as a new strain of Scolecobasidium tshawytschae through the morphological characteristics and phylogenetic analysis of 18S rDNA sequence. Gibberellins production and plant growth promoting ability of genus Scolecobasidium was reported for the first time in the present study.

  • To deal with pathogens, plants have evolved sophisticated mechanisms including constitutive and induced defense mechanisms. Phytohormones play important roles in plant growth and development, as well as in the systemic response induced by beneficial and pathogen microorganisms. In this work, we identified an Aspergillus ustus isolate that promotes growth and induces developmental changes in Solanum tuberosum and Arabidopsis thaliana. A. ustus inoculation on A. thaliana and S. tuberosum roots induced an increase in shoot and root growth, and lateral root and root hair numbers. Assays performed on Arabidopsis lines to measure reporter gene expression of auxin-induced/ repressed or cell cycle controlled genes (DR5 and CycB1, respectively) showed enhanced GUS activity, when compared with mock-inoculated seedlings. To determine the contribution of phytohormone signaling pathways in the effect elicited by A. ustus, we evaluated the response of a collection of hormone mutants of Arabidopsis defective in auxin, ethylene, cytokinin, or abscisic acid signaling to the inoculation with this fungus. All mutant lines inoculated with A. ustus showed increased biomass production, suggesting that these genes are not required to respond to this fungus. Moreover, we demonstrated that A. ustus synthesizes auxins and gibberellins in liquid cultures. In addition, A. ustus induced systemic resistance against the necrotrophic fungus Botrytis cinerea and the hemibiotrophic bacterium Pseudomonas syringae DC3000, probably through the induction of the expression of salicylic acid, jasmonic acid/ethylene, and camalexin defense-related genes in Arabidopsis.

  • Objective: The present study was conducted to evaluate the effects of dietary supplementation with Bifidobacterium animalis, Agave fructans, and symbiotic of both encapsulated on growth performance, feed efficiency, blood parameters, and immune status in broiler chickens, and to compare these with diets including antibiotic growth promoters and without additives. Methods: A comparative experimental study was carried out with 135 male Ross 308 broiler chickens. Each trial was divided into 5 equal groups. Control group (CON) received a standard diet without growth promoter; GPA, a standard diet with colistin sulfate and zinc bacitracin (0.25 g/kg of feed); PRE, a standard diet with 1% Agave fructans; PRO, a standard diet with Bifidobacterium animalis (11.14±0.70 log CFU/g); SYM, a standard diet with B. animalis and Agave fructans. Results: A significant decrease in food consumption was found for the GPA, PRE, and SYM, compared to the CON group. The results show a better feed conversion index in PRE and GPA with respect to the CON group with the highest conversion index. Interestingly, the weight of the gastrointestinal tract shows a statistically significant difference between GPA and PRE groups. Moreover, the length of the gastrointestinal tract of the GPA group was less than the PRE group. In the total leukocyte count, there was a statistically significant increase in the GPA group compared to the CON, PRE, and PRO groups, and the heterophiles-lymphocytes index was lower in PRO. Regarding the cytokines, interleukin 10 (IL-10) decreased in PRO compared to CON and PRE, while IL-1β increased in the SYM group. Conclusion: Alternative treatments were shown to achieve similar productive results as growth-promoting antibiotics and showed improvement over diet without additives; however, they have immunomodulatory properties and improved the development of the gastrointestinal tract compared to the treatment of growth-promoting antibiotics.

  • The study aimed to investigate the effects of supplemented sodium butyrate on the in vitro rumen fermentation and growth performance of Hanwoo calves. In total, four treatments were employed according to the sodium butyrate levels: no addition (control), an addition of 0.1% (treatment 1), an addition of 0.3% (treatment 2), and an addition of 0.5% (treatment 3). After 48 hours of fermentation, the ruminal pH was found to be higher in T1 than in C. Total volatile fatty acids were significantly higher in T2 and T3 than in C. The ratio of acetate and propionate was significantly lower in T1 and T3 than in C. In this study, the optimal concentration to promote rumen fermentation was found to be 0.3%, i.e., T2, and an experiment on Hanwoo calves at a farm was conducted. However, there were no significant differences between the treatment groups in terms of the daily weight gain, feed conversion ratio, and final body weight in the feeding experiment. Also, there were no significant differences in the body length, withers height, and height at hip cross between the control and the treatment groups. The addition of 0.3% sodium butyrate was most effective at promoting in vitro rumen fermentation, but it did not significantly affect the growth performance when fed to Hanwoo calves. This indicates that the addition of sodium butyrate improved rumen fermentation but did not have a growth-promoting effect. Future studies need to compare growth and carcass performance outcomes to confirm long-term effects.

  • The effects of food grade fructooligosaccharide (FOS), isomaltooligosaccharide (MOS), galactooligosaccharide (GOS), and inulin on the growth of five strains of bifidobacteria in fermented milk were investigated. Their effect on culture viability during refrigerated storage was also determined. FOS showed the highest growth-promoting activity for all bifidobacteria except for Bifidobacterium bifidum. Growth rates of B. adolescentis, B. breve, and B. infantis were stimulated by oligosaccharides and inulin, whereas B. longum growth was stimulated by the oligosaccharides but not inulin. In contrast, growth of B. bifidum was enhanced only by inulin. Both acetic and lactic acid production by Bifidobacterium spp. was also enhanced in the presence of 5.0% oligosaccharides. The viability of bifidobacteria cultured with oligosaccharides and inulin, particularly with FOS, was significantly higher than control cultures after 4 weeks of refrigerated storage. The utilization of oligosaccharides is likely to enhance the growth rate, activity, and viability of bifidobacteria.

  • Young children need continuous care and fostering by their family. They help children organize and develop their potential and grow to be and integrated individuals. Children are influenced by then family at first and continuously when they grow up and develop their capability. Especially, mothers spend a lot of time with time to their children, encourage children's growth, give advice, and do their best to take care of their children. The ethnographic study is to understand the patterns and rules of human behaviors. This study utilized this method in order to interpret the maternal health promoting behaviors for their children. The data were collected through the participant observation and direct interview for about 18 months in P city. The participants were 7 mothers, from 32 to 37 years old. They have children of ages 3 to 10 and 1 or 2 children in total. The data were analyzed through the Spradley's Ethnographic method and the results were summarized as follows : The viewpoints which influence maternal health promoting behaviors include “having childlike appearance”. “having childlike character”, “living without illness”, and “eating well”. The maternal health promoting behaviors for children are classified as “adapting to nature”, “supporting of ability”, “sharing with the family”, “training”, and “praying”. The adapting behaviors include “recognizing child's innate character”, “controlling maternal desires”, “preparing natural food”, which includes breast feeding. The supporting behaviors include “recognizing childlikeness”, “empowering”, and “restricting certain actions to preventing accidents”. In order to promote child's health, it is essential to promote mother's health first of all. The sharing with the family includes “promoting family concord or acquaintanceships concord” and “adapting to circumstances beyond family”. The training behaviors include “forming good habits” and “having good moral value”. It is very important to form good habits in childhood. The praying behavior include “waiting for opportunities” and “endeavoring activity to promote child's health”. The above 5 behaviors by mothers appeared to be able to promote children's health. The results of this study can be utilized to provide the basic information necessary to develop the patterns of maternal health promoting behaviors consistent with our culture and can contribute us develop the body of knowledge about the maternal health promotion for children in nursing.

  • The purpose of this study is to investigate the level of verbal abuse experiences, emotional labor, and health-promoting behaviors of nurses in small and medium hospitals and to identify the relationship between them. Participants were 138 nurses from 2 small-medium sized hospitals. Collected data were analyzed using t-test, ANOVA, and Pearson's correlation coefficients with the SPSS 20.0 for Windows Program. As a result of the study, 82.7% of them experienced verbal abuse, and there were differences in the degree of health- promoting behavior according to gender (p=.032) and department (p=.009). Besides, it was found that emotional labor was related to health-promoting behavior (p=.039), and spiritual growth (p=<.01), and stress management (p=.028) as sub-factors. Accordingly, this study will be used as basic data for developing strategies and customized programs to reduce emotional labor, increase health-promoting activities, and contribute to the stable securing of nursing personnel.
