There are different kinds of the pseudo-mass of the gallbladder(GB) such as GB stones, GB polyps, GB sludge, and these can be differentiated by simple-ultrasonogram(USG). The most common symptoms of GB polyps are abdominal pain(RUQ), dyspepsia, jaundice, but usually there are no symptoms. GB polyps are commonly treated with a cholecystectomy if 10 mm or more in diameter. Pseudo-mass of the GB is regarded as products of stagnation of the Liver Ki in Oriental Medicine. The patient suffered from mild fever. abdominal pain(RUQ), and jaundice. He was diagnosed with a GB polyp(10 mm), liver cyst(12 mm) by simple USG. We treated him with Acupuncture, Herbal Medicine(Hoinsamgum-tang). After three days of treatment, the symptoms improved, and after one month the GB polyp was removed on the follow up of USG.

The fruit of Gleditsia sinensis has been extensively used as a key ingredient of an herbal remedy for the treatment of various inflammatory diseases in traditional Korean Medicine. However, the reason of using the fruit of G. sinensis for the remedy is unclear. Since Nuclear factor (erythroid-derived 2)-like 2 (Nrf2) is a key anti-inflammatory transcription factor, which is activated by the fruit of G. sinesis, we examined whether other plant parts of G. sinensis are also capable of suppressing inflammatory responses by activating Nrf2. Water extracts of various parts of G. sinensis were prepared and tested for Nrf2 activation by reporter assay and western blot analysis. Our results show that the hull of G. sinensis is the most potent in activating Nrf2. Sequential organic solvent extraction of the hull show that all the fractions had a higher potency in activating Nrf2 than the water extract, albeit differential degrees. The hull originated from Korea in general activated Nrf2 strongly compared to that of China. Chloroform fraction of the hull was further examined, showing that the fraction induced nuclear localization of Nrf2, indicative of activated Nrf2, and Nrf2-dependent gene expression including NAD(P)H dehydrogenase quinone 1 (NQO-1), glutamate-cysteine ligase catalytic subunit (GCLC), and heme oxygenase - 1 (HO-1). Therefore, our results show that, among other plant parts examined in this study, the hull of G. sinensis is the most potent, providing the experimental basis for the use of the hull of G. sinensis as an active ingredient for an anti-inflammatory remedy.

There are variations among grapevine genotypes in the levels of tolerance to cold, and cold-hardiness of grapevine has been affected by the change of short-term environment during over-wintering. In this study, the responses of vines to cold in open field and rain-shelter system were investigated to obtain useful information in increasing the tolerance to cold in grape cultivation. Total carbohydrate content of bearing mother branches was higher in the rain-shelter system than in the open field, and lower in the branches of 'Muscat Bailey A' than in 'Campbell Early' and 'Kyoho'. Bud-burst and shoot growth were better in the rain-shelter system than in open field, whereas there is no significant difference among the treatments of net beside vines. There was also low incidence of gray mold in rain shelter system. Stilbene compounds such as t-piceid, resveratrol, piceatannol, c-piceid were accumulated in the cold-treated shoot from vine cuts harvested in rain shelter system. Genes of chalcone isomerase, manganese superoxide dismutase, proline rich protein 2, and temperature induced lipocalin were highly expressed in the cold-treated shoot from vine cuts harvested in rain shelter system. While there was not change of air temperature, but high reduction of wind speed in the rain shelter system compared to open field, and increase in the reduction of wind speed by net treatment. The damage of grapevines by cold in the extreme low temperature could be reduced by keeping them in the rain shelter system with net during winter season.

This study was conducted to investigate the effect of 1-MCP, an ethylene action inhibitor, and several postharvest treatments including ethylene scrubbing on fruit quality and respiration for keeping marketability in 'Janhowon Hwangdo' peach ($Prunus$ $persica$ Batsch). 1-MCP at the rate of $1.0{\mu}L{\cdot}L^{-1}$ showed best results in maintenance of fruit firmness and external appearance such as skin color. The ethylene production was strongly reduced by 1-MCP treatment at 0.5 or $1.0{\mu}L{\cdot}L^{-1}$ but respiration rate was only suppressed at $1.0{\mu}L{\cdot}L^{-1}$ during 6 days of shelf life at $20^{\circ}C$. Mature fruits (harvested 1 week before full commercial maturity) were much highly responsive to $1.0{\mu}L{\cdot}L^{-1}$ of 1-MCP compared to those of commercial maturity. At the concentration of $0.5{\mu}L{\cdot}L^{-1}$ of 1-MCP did not affect fruit marketability compared to untreated control. Beneficial effects of carbon ceramic as an ethylene scrubber were also found such as delay of firmness loss and deterioration of external appearance at $10^{\circ}C$, but these positive effects on fruit quality remained for only 5 days. The application of ethylene scrubber on the shipping carton boxes was effective on keeping firmness of immature fruit pretreated with 1-MCP when compared with mature fruit.

Gromwell (LE, Lithospermum erythrorhizon), a perennial herbal plant, has been used for the treatment of various problems associated with atopic dermatitis of the skin, such as water loss, epidermal hyperproliferation, and severe inflammation. Previously, it was shown that oral supplementation with a 70% ethanol extract of gromwell prevented the development of atopic dermatitis in NC/Nga mice. In this study, in order to identify the fraction that mediates gromwell's efficacy, the dietary effects of water and ethyl acetate fractions from the ethanol extract of gromwell were assessed in the development of dermatitis using NC/Nga mice. Dietary supplementation of the hot water fraction significantly reduced scores for epidermal hyperproliferation in parallel with a marked increase of ceramides. Supplementation of the gromwell hot water fraction also decreased scratching behavior, which was accompanied by a decrease in plasma levels of IgE. These results showed that the hot water fraction of the gromwell ethanolic extract prevented the development of atopic dermatitis by increasing ceramides in NC/Nga mice.

This study was undertaken to determine the effects of dietary supplementation with herbal extracts of Portulaca oleracea L. (POL), on the reproductive performance, blood profiles, immune response, and fecal microbial population in multiparous sows. On the basis of initial body weight, a total of 20 multiparous sows (Landrace×Yorkshire; 229.2±1.15 kg) were randomly allotted to 2 treatment groups, each including 10 replicates. The dietary treatments were administered during the lactation period, and included a corn-soybean meal-based diet (control group) and diet supplemented with 0.05% POL. Throughout the experimental period, no significant differences were observed between the two diet groups for body weight, backfat thickness, and reproductive performance. Blood profile analysis revealed significantly decreased lymphocyte concentrations and IL-1β levels (p<0.05), and increased serum IgG levels (p=0.051), of sows consuming the POL supplemented diet. Furthermore, coliform counts tended to decrease in sows consuming diet supplemented with POL (p=0.063). Taken together, our results indicate that POL supplemented diets exert beneficial effects on blood profiles, immune response, and fecal microflora of multiparous sows, without any negative effect on the reproductive performance.

Purpose : The purpose of this study was to evaluate the attitudes of middle-school students about height and their behaviors related to height gain. Methods : One thousand four hundred twenty two middle-school students were included. We requested that the students complete a battery of questionnaires asking about problems associated with height. Results : There was a clear difference between real height and desired height. Most students (83.7%) had height dissatisfaction. Most students (91.1%) were concerned about their height. Few students made efforts to improve their height, even though most students had height dissatisfaction and were concerned about their height. Herbal medicine had a tendency to become popularized in treatments for height. Students generally did not judge their friends by height, but there was a small tendency to ignore shorter friends and to feel a sense of inferiority around taller friends. Most students had a greater desire to have a beautiful face than a good body, especially to be tall. Most students thought that there would be some handicaps in life if they had a short stature. Conclusion : The attitudes and concerns about height in adolescence should be understood, and recognized as one aspect of treatment for problems associated with height.

The present study aimed to evaluate the effect of radiation mutant Perilla frutescens var. crispa on bone metabolism and the inflammatory response in a monosodium iodoacetateinduced rat model of osteoarthritis. radiation mutant Perilla frutescens var. crispa was administered orally at doses of 25, 50 or 100 mg/kg/day for 2 weeks before direct injection of monosodium iodoacetate (3 mg/50 μl of 0.9% saline) into the intra-articular space of the rats' right knees. The rats subsequently received the same doses of oral radiation mutant Perilla frutescens var. crispa for another 4 weeks. It was evaluated that the treatment effects based on serum biomarkers, and morphological and histopathological analysis of the knee joints. Compared with those in control rats, the radiation mutant Perilla frutescens var. crispa treatments significantly reduced the serum levels of inflammation, bone metabolism markers (i.e., COX-2, LTB4, MMP-3, and COMP), and the amount of fibrous tissue. Otherwise, it was significantly increased the concentration of TIMP-1 and calcitonin. In addition, the radiation mutant Perilla frutescens var. crispa treatments effectively preserved the knee cartilage and synovial membrane. As a result, it indicates that radiation mutant Perilla frutescens var. crispa prevented and alleviated osteoarthritis symptoms. Thus, radiation mutant Perilla frutescens var. crispa can be used in food and drug material for the management of osteoarthritis.

Transient receptor potential vanilloid 3 (TRPV3) is a non-selective cation channel with modest permeability to calcium ions. It is involved in intracellular calcium signaling and is therefore important in processes such as thermal sensation, skin barrier formation, and wound healing. TRPV3 was initially proposed as a warm temperature sensor. It is activated by synthetic small-molecule chemicals and plant-derived natural compounds such as camphor and eugenol. Schisandra chinensis (Turcz.) Baill (SC) has diverse pharmacological properties including antiallergic, anti-inflammatory, and wound healing activities. It is extensively used as an oriental herbal medicine for the treatment of various diseases. In this study, we investigated whether SC fruit extracts and seed oil, as well as four compounds isolated from the fruit can activate the TRPV3 channel. By performing whole-cell patch clamp recording in HEK293T cells overexpressing TRPV3, we found that the methanolic extract of SC fruit has an agonistic effect on the TRPV3 channel. Furthermore, electrophysiological analysis revealed that ${\gamma}$-schisandrin, one of the isolated compounds, activated TRPV3 at a concentration of $30{\mu}M$. In addition, ${\gamma}$-schisandrin (${\sim}100{\mu}M$) increased cytoplasmic $Ca^{2+}$ concentrations by approximately 20% in response to TRPV3 activation. This is the first report to indicate that SC extract and ${\gamma}$-schisandrin can modulate the TRPV3 channel. This report also suggests a mechanism by which ${\gamma}$-schisandrin acts as a therapeutic agent against TRPV3-related diseases.

To develop food and organoleptic quality of gochujang 0, 3, 4, and 5% of sweet persimmon powder were added to Korean traditional red pepper paste during fermentation and microbiological and organoleptic characteristics were investigated. The total bacteria count of the gochujang tended to increase slowly until a level of $10^8$ CFU/g with increasing fermentation time. There was no significant difference (p <0.05) between the control and the treatment during fermentation. The number of yeast and mold was $10^4-10^5$ CFU/g during fermentation. Sensory evaluation after 30, 60, and 90 days of fermentation showed that addition of sweet persimmon powder to the gochujang did not affect its color, but the level of sweetness and umami, increased as additional level of sweet persimmon powder increased. In the overall acceptabilty, there was no significant difference (p <0.05) until 30 days of fermentation and the gochujang added with 4% sweet persimmon powder showed the highest organoleptic value. And it showed high score in sweetness, umami and overall acceptability at the end of fermentation. The results indicated that 4% additional level of sweet persimmon powder was the best making gochujang.
