  • It was to test the efficiency of essence containing scalp derived Leuconostoc mesenteroides extract on relieving hair loss and the possibility of the usage as the functional cosmetic's material. 41 subjects were classified as the control and test group and for 24 weeks, from Apr. 15th 2021 to Nov. 4th 2021, they were double blindness, contrast samples, single organs, and randomized human applicating tests were performed. The amount of hair had meaningful change (p<0.001) seen through phototricogram in 8,16,24 weeks each, and could tell the difference by researcher's bare eye after 24 weeks. Since there were meaningful changes (p<0.017) in subjective evaluation of the subject on after 8,16,24 weeks time, Essence which contains 1% of L. mesenteroides has efficiency on hair loss. Therefore, L. mesenteroides is expected to be used as various cosmetics to prevent hair loss.

  • The effect of garlic powder were investigated on health of stamina through mouse test. The swimming time of mouse was measured to determine the effect of garlic powder on stamina. When 2,000 and 200mg/kg of garlic were treated to mouse, swimming times were $124.8\pm61.1$ and $100.4\pm61min$, respectively. Those time were significantly longer than untreated control mouse which showed $67.1\pm15.5min$ of swimming time.

  • We assessed the effects of intravenous (IV) ascorbic acid administration on fatigue in women undergoing laparoscopic myomectomy. We analyzed the secondary endpoint results of a randomized, double-blind, placebo-controlled trial. Fifty patients undergoing laparoscopic myomectomy received IV ascorbic acid (2g) or placebo (randomly 1:1 ratio) intravenously during surgery. On day 2 post-surgery, we measured the level of fatigue using the Brief Fatigue Inventory-Korean version. Forty-five women (experimental arm 23, control arm 22) were eligible for analysis after 5 women (experimental arm 2, control arm 3) were excluded due to withdrawal of consent, cancellation of surgery or non-measurement of the endpoints. The baseline and operative characteristics were similar between arms and the global fatigue score of the experimental arm (4.56 ± 2.63) was not significantly different from that of the control arm (5.21 ± 2.02, P = 0.351). However, the fatigue score of the experimental arm tended to be lower than that of the control arm in most domains. IV ascorbic acid administration did not significantly reduce the level of fatigue in women undergoing laparoscopic myomectomy as compared to placebo. More research is needed to better understand the effects of ascorbic acid on fatigue in surgical patients.

  • The present study was carried out to investigate the acute oral toxicity and anti-obesity effects of a diglyceride preparation containing conjugated linoleic acid (DG+CLA). To test its acute oral toxicity, the DG+CLA was injected into 30 rats (15 males and 15 females) at dosage of 2,000 mg/kg and 5,000 mg/kg. Mortality rates, clinical signs, and body weight changes were monitored for 14 days following administration. According to the results, the lethal dose ($LD_50$) of DG+CLA was determined as >5,000 mg/kg in both sexes. There were no significant changes in general conditions, clinical signs, body weight, and gross lesions between the vehicle control and DG+CLA groups. For the anti-obesity studies, obese Zucker rats were randomly divided into 4 groups and fed saline, soybean oil, diglyceride, and DG+CLA, respectively, for 8 weeks. The DG+CLA groups presented significant differences in body weight, food efficiency ratio, serum lipid levels, and fat weight. Overall, the results showed that the DG+CLA did not have acute oral toxicity and reduced body weight, serum lipid levels, and fat gain.

  • Blueberry Makgeolli was made with rice by adding different amounts of blueberries, and the fermentation characteristics of Makgeolli were studied during the fermentation process. The pH was the highest (6.6) at the beginning of the fermentation and decreased when the ratio of blueberries increased. The pH was remarkably reduced until the second day, and remained constant until the seventh day of fermentation. The total acidity was significantly increased until the fourth day of fermentation, and remained constant until the seventh day. Sugar contents ($^{\circ}Brix$) and reducing sugar reached the maximum after 2 days of fermentation, and gradually decreased until the seventh day. Alcohol content of control (0% blueberries) increased continuously until the seventh day of fermentation and was at 13.4%. Alcohol content of 20% blueberry Makgeolli reached the maximum on the 4th day of fermentation and slowly decreased to 10.2% until the seventh day. Total viable bacterial cell counts and yeast cell counts showed the maximum values at the third day of fermentation. In sensory evaluation, the color of the control sample was the most favored by the panelists whereas 20% blueberry sample was the least favored. There were no significant differences in flavor and taste, but overall preference was high in Makgeolli with less than 10% of blueberries.

  • The aim of this study was to examine the effect of polycan-calcium gluconate complex on the levels of immune and inflammatory mediators in gingival crevicular fluid and serum from patients with periodontitis. A total of 39 patients with periodontitis took placebo (placebo group) or polycan-calcium gluconate complex (treatment group) twice a day for 4 weeks. At baseline and 4 weeks, gingival crevicular fluid (GCF) and blood was collected from each subjects. The secretion level of interleukin $(IL)-1{\beta}$ in GCF was measured by enzyme-linked immunosorbent assay (ELISA). Western blot analysis was conducted to determine the expression of matrix metalloproteinase (MMP)-8 and tumor necrosis factor $(TNF)-{\alpha}$ in GCF. Serum samples were analysed for MMP-8 by ELISA and C-reactive protein (CRP) by turbidimetric immuno assay. MMP-8 and $TNF-{\alpha}$ were significantly decreased in the treatment group at 4 weeks. The level of $IL-1{\beta}$ in the treatment group was significantly lower than those of the placebo group. No differences were observed in CRP levels. Taken together, these data indicate that taking of polycan-calcium gluconate complex led to reduction of inflammatory biomarkers in serum and GCF of periodontitis patients.

  • The effects of ginseng saponin on the germination and early growth of rice seeds (Oryza sativa L.) were investigated. The early growth (length) of test rice seeds which were rinsed for 60 hrs in $10^{-4}$% saponin solution prior to transplantation to water agar bed was about 20% faster than that of control seeds, It was also found that the amylase activity of the seeds was most active when the seeds were rinsed in 10-4% saponin solution for 48 hrs. In vitro investigation showed that the amylase activities were stimulated about 30% by the treatment of $10^{-5}$% saponin solution compared with control group. From the above results, it seems that the ginseng saponin might activate amylase of rice seed during germination, resulting in rapid growth of rice.

  • In this study, the effects of a mixture consisting of vitamin E, vitamin C, pycnogenol and evening primrose oil (mixture LGNC-5) on ultraviolet light (UV) induced pigmentation and wrinkle reductions of normal healthy volunteers were studied. In a double-blind placebo-controlled study, each of 54 subjects took daily either 4 capsules of the mixture LGNC-5 (Group ABC; 282.5 mg/capsule) or placebo (Group Ganada). We irradiated 2.5 MED UV on the upper arms and measured the whitening effect by colorimeter-based L value. The level of wrinkle reduction was determined by image analysis using skin replica around the crow' feet, and the level of serum vitamin E was determined at baseline and 12 weeks. After 12-week oral administration, the treated group showed a significant reduction in skin pigmentation and wrinkles compared with the placebo group (p = 0.011 and p = 0.000005, respectively). Also, the level of serum vitamin E was significantly increased in the treated group after 12-week oral adminstration of the mixture compared with that in the placebo group (p = 0.0001). In conclusion, 12-week oral administration of LGNC-5 as a dietary supplement could be effective to reduce both UV induced pigmentation and skin wrinkle without side effects.

  • 알비노 기니픽의 피부에 Microsporum gypseum을 접종한 후 체중 kg당 20, 40 및 80mg의 terbinafine을 접종 당일부터 9일간 연속 투여하였다. 대조군의 피부는 인설과 가피를 동반한 현저한 염증이 발생되었다. 이와 대조적으로 terbinafine을 경구투여한 처치군에서는 피부 증상이 현저하게 차도를 보였다. 진균학적인 평가를 위해 모근침범시험을 실시 하였다. 체중 kg 당 20∼80mg의 terbinafine을 경구투여한 처치군은 진균학적으로 97∼100%의 치료효과를 나타냈으며, 대주군에서는 치료효과가 전혀 없었다.
