This study was carried out to investigate the antioxidative activity and cytotoxicity on human KB cell of extract from Rhododendron mucronulatum flower, and also to determine the contents of total polyphenol and flavonoid. The methanol extract of Rhododendron mucronulatum flower was fractionated with various solvents such as hexane, chloroform, ethyl acetate, butanol and water. The DPPH radical scavenging activities of ethyl acetate fraction had stronger activity than other fractions. So, antioxidative substances of ethyl acetate fraction were crude purified by silica gel column chromatography. The DPPH radical scavenging activities of crude purified fraction 2 and 3 were more than 90% at 40 ppm. In the presence of $100{\mu}g/mL$, growth inhibition on human KB cell by WST-1 assay showed 81.2% in chloroform fraction and 74.6% in hexane fraction. The contents of total polyphenol and flavonoid of ethyl acetate traction were 32.70% and 20.30%, respectively, The antioxidative activity showed correlation with total polyphenol and flavonoid contents.

This study aimed to assess the in vitro safety of a probiotics mixture (Lactobacillus acidophilus PBS066, Lactiplantibacillus plantarum PBS067, and Limosilactobacillus reuteri PBS072), along with its inhibitory effect on carbohydrate digestion. All three strains met the antibiotic resistance profile of the European Food Safety Authority (EFSA) guidelines. None of the strains exhibited hemolytic activity or cytotoxicity against Caco-2 cells. Strains PBS067 and PBS072 inhibited α-amylase activity, whereas all three strains suppressed α-glucosidase activity, indicating that the mixture might limit carbohydrate digestion in the gastrointestinal tract. These findings support the safety of this probiotics mixture and its potential to modulate carbohydrate metabolism in the gut.

Jeju Sasa borealis (S. borealis) is indigenous to the Halla Mountain area of Jeju Island, Republic of Korea. However, its dominance has retarded the development of other plant species and lowered biodiversity in this region. The aim of this study was to determine whether S. borealis silage (SS) supplementation affects the chemical composition and antioxidant activity in the fresh meat of Korean native goats (Capra hircus coreanae). The experiment was conducted on 12 Korean native goats at the finisher stage. The feeding groups were the Control (total mixed ration, TMR) and the Treatment (80% TMR + 20% SS). The animals were adapted for two weeks and then subjected to a six-month breeding experiment. Meat samples were excised from the neck, loin, rib, front leg, and hind leg of the slaughtered animals. The meat derived from the treatment group contained more taurine and anserine than that derived from the control group. Both groups did not significantly differ in terms of ω-6/ω-3 fatty acid ratio. The loin and front leg of the treatment group contained significantly higher vitamin E levels than those of the control group. DPPH, ABTS, and FRAP analyses disclosed that the loin and front leg had significantly higher antioxidant activity (p<0.05) than the other parts. Moreover, the loin and front leg cuts of the treatment group had higher antioxidant activity than those of the control group. The present study demonstrated that S. borealis supplementation could effectively improve Korean native goat meat quality.

Rice is the primary main dish of Traditional Korean diet. Although there have been changes in food consumption and nutrient intake among Koreans, traditional dietary pattern is stil dominant among Koreans. Traditional Korean diet has emphasized breakfast, which is the most frequently missed meals in Korea today but important for daily work performance and health. Compared to diets of the U.S. and Greece, Korean diet is high in carbohydrate and low in fat and cholesterol due to low intake of meat. Koreans also consume large amount of plant food, which makes fiber content of diet to be high. However fruit and milk consumption tends to be low in Korea. Koreans use fermented food, including kimchi, very frequently as well as foods cooked and consumed at high temperature and over direct fire. Traditional cooking methods are time consuming which limits the usage among modern city dwellers with working women. Despite the strengths of traditional Korean diets in reducing risk factors of chronic diseases, preservation of the tradition in modern Korean society requires special attention and efforts to make them more adaptable to contemporary life styles.

The aim of this study was to report a successful pregnancy using completely immotile frozen-thawed spermatozoa selected by laser. A single laser shot was used to detect the presence of viable immotile spermatozoa in fresh and frozen-thawed testicular spermatozoa. The viability rate was 55.8% after the laser detection, and cryopreservation was carried out immediately. The thawing test was performed on the day of oocyte pick-up, and no motile sperm were observed after extending the culture for another 4 hours, while a survival rate of 39.8% was detected using the laser. In all, five mature oocytes were injected, resulting in four cases of normal fertilization (80%) on day 1. Further, two high-quality day 3 embryos were transferred, which resulted in a singleton pregnancy. Our study demonstrates that completely immotile spermatozoa are worth cryopreserving for further intracytoplasmic sperm injection, which provides a new insight into male fertility preservation in cases of completely immotile spermatozoa.

To examine the levels of preservatives that occur naturally in food, wild plants used as commercial teas, rice cakes, or spices were studied according to the method of the Korean Food Code and analyzed with a gas chromatograph and HPLC. The levels of the natural preservatives (sodium dehydroacetate, sorbic acid, benzoic acid, methyl p-hydroxybenzoate, ethyl p-hydroxybenzoate, isopropyl p-hydroxybenzoate, propyl p-hydroxybenzoate, isobutyl p-hydroxybenzoate, butyl p-hydroxybenzoate, and propionic acid) in 21 cases were investigated against 15 kinds of wild plants. Six of 15 kinds of wild plants, such as pine needles, bamboo leaf, kudzu leaf, ramie leaf, mugwort, and nut pine leaf, were confirmed to have had sorbic acid, benzoic acid, and propionic acid. 8.201-21.839 mg/kg of benzoic acid was detected in the bamboo leaf, ramie leaf, pine needles, mugwort, kudzu leaf, and nut pine leaf. The sorbic acid contents of the bamboo leaf and the kudzu leaf were 5.630-24.995 mg/kg, respectively. The propionic acid content of the ramie leaf was 61.324-62.726 mg/kg. Nine kinds of wild plants, such as the Korean berchimia leaf, taro leaf, sasa borealis, lotus leaf, kuansh, chrysanthemum zawadskii, oak tree leaf, Chinese pepper leaf, and persimmon leaf, were not detected at the levels of the natural preservatives.
