  • To study on antioxidant effects in the liver of 40-week-old mouse, the sample were orally pretreated 5mg/kg/day for 5 days with red ginseng saponin components(total saponin, protopanaxadiol saponin, protopanaxatriol saponin, ginsenoside-Rd, ginsenoside-Re, compound-K) for 5 days. The ability of saponin to protect the mouse liver from oxidative damage was examined by determining the activity of superoxide dismutase(SOD), glutathione peroxidase(GPx) and the contents of glutathione, the level of malondialdehyde, The only protopanaxadiol among the ginseng saponin fractions was significantly increased the hepatic SOD activity(p<0.01). The red ginseng saponin induced a slight increase of GPx activity, especially ginsenoside Rd, compound K and protopanaxatriol treatments significantly increased its activity. The content of glutathione was significantly increased by total saponin, protopanaxadiol and ginsenoside Rd(p<0.01), but the oxidized glutathione level was lowered in all the red ginseng saponin. Finally, the level of malondialdehyde was significantly decreased by ginsenoside Rd and protopanaxadiol. In conclusion, protopanaxadiol and ginsenoside Rd among the saponin fraction were especially increased in the activity of hepatic antioxidative enzyme and decreased the lipid peroxidation that was expressed in term of MDA formation. This comprehensive antioxidant effects of red ginseng saponin seems to be by a certain action of saponin other than a direct antioxidant action.

  • Five cases infected with Rhabditis sp. were detected in a survey to examine the stool specimens from rural primary school children. A large number of the larvae of Rhabditis sp. detected by the direct cellophane thick smear were cultured by the alter paper method. The eBamination was carried out in April through June, 1980 in Tangjeong-Myon, Ahsan.Gun, and in September 1983 in Sandong-Eup, Yeongwol-Gun. The results obtained in this study were as follows: 1. Prevalence: Out of 925 children, 5(0.54%) children were found to be positive. The number of the detected larvae was 110/0.1gm of feces in case 1, 35 in case 2, 130 in case 3, 86 in case 4 and 62 in case 5. 2. Larvae: The larvae were prepared by means of the direct fecal smear and measured by a micrometer equipped in the microscope. Twelve (12) through 15-day old larvae in culture were $197.1{\mu}{\textrm{m}}$ long in average, and the maximum size of the matured stage larvae was $884.0{\times}25.9{\mu}{\textrm{m}}$. However, the length variation was ranged as 173.0 to $884.0{\mu}{\textrm{m}}$. 3. Adults: The size of clubbed adult female was $1, 357{\mu}{\textrm{m}}(1, 176~1, 419)$ in length and $80{\mu}{\textrm{m}}(79~82)$ in width. Length of buccal cavity was $33{\mu}{\textrm{m}}$. A long cylindrical esophagus($273{\mu}{\textrm{m}}$) of the worms with a valved posterior cardiac bulb and with median bulbar swelling was morphologically indicated. Ditance from mouth to vulva was occupied 58% of body length. Male worm was $1, 006{\mu}{\textrm{m}}(890~1, 148)$ in length and $49{\mu}{\textrm{m}}(48~49)$ wide. Caudal alee of bursa and spicules ($75{\mu}{\textrm{m}}$ in length) were well developed. 4. Eggs: The oval shaped eggs in the female uterus, when cultured, were $66{\times}56{\mu}{\textrm{m}}$ in sixte, and the eggs laid by the adult could not be detected. So, reproduction might be thought to be ovoviviparity. 5. The five cases were re-examined during the period from the 1st to the 3rd week after stool examinations, but Rhabditis sp. were detected again in 4 cases in 1st week. When they were examined in 3rd week, larvae could not be detected. So, it was thought that the infection of Rhabditis sp. to humans was facultative.

  • The purpose of this study was to investigate the snack and beverage intake patterns of students by body mass index groups (BMI <18.5, 18.5-23, 23-30, ${\geq}$30). Questionnaires were completed by 1381 high school students in Seoul, Incheon, and Gyeonggi-do, the area of Korea's capital region. There were no significant differences in skipping meals for overweight (BMI 23-30 and ${\geq}$30) or under-nourished (BMI <18.5) students. Girls skipped dinner more frequently than boys. Boys and girls both preferred meat and disliked fish regardless of BMI. Girls with BMI 23-30 disliked vegetables. Boys and girls would rather have crackers, candies, and chocolates than potatoes as snacks regardless of BMI. Obese boys (BMI ${\geq}$30) preferred flour-based food, fast food, and other food as snacks. Girls liked fruits more than boys. Snacks were eaten 2-3 times per week, when students were hungry or bored. There were no significant differences in the frequency or reasons (habitual, stressed) for snack consumption by BMI. Girls liked juice more than boys did, and boys preferred soda water more than girls did. Both the under-nourished (BMI <18.5) boy and girl groups had more juice than the overweight (BMI 23-30 and ${\geq}$30) groups. Obese (BMI ${\geq}$30) boys did not more drink soda water than other BMI groups. The under-nourished (BMI <18.5) boy group had more soda water than the normal (BMI 18.5-23) and overweight (BMI 23-30) groups. Girls in the overweight (BMI 23-30) group had 2 more cups of soda water a day than the normal group (BMI 18.5-23). Therefore, skipping meals and beverage intake patterns might influence BMI.

  • Hemophilia B is a rare blood coagulation disorder. Complications such as bleeding and hematoma can cause necrosis of flaps, wound disruption, and the disturbance of wound healing. In particular, guidelines for flap operations in hemophilia B patients have still not been defined, and case reports are rare. We reconstructed the heel of a 41-year-old male hemophilia B patient using a reverse sural artery flap operation. The patient presented with mild hemophilia, having 27% of the normal value of coagulation factor IX. Coagulation and the changing value of the coagulation factor were regularly measured, and 70% of the normal value of coagulation factor IX was maintained through the injection of recombinant coagulation factors and antihemorrhagics. Hematoma developed twice (postoperative day [POD] 5 and POD 7) and in each case the hematoma was removed. Injections of recombinant coagulation factors and antihemorrhagics were continuously administered until postoperative week 2. When the coagulation factors were within normal ranges. In this article, a hemophilia B patient underwent reverse sural artery flap surgery and the healing progress was analyzed. We conclude that higher than baseline levels of coagulation factors are needed for successful healing in reverse sural artery flap surgery.

  • The antibacterial effects of a combination of Coptidis rhizoma and Galla rhois extracts (CGE) were evaluated in piglets. The minimum bactericidal concentration of CGE was 2.0 mg/mL. Thirty 5-week-old piglets were challenged with Campylobacter (C.) coli after allocation to three different groups, a control and two treatment groups fed with CGE at 2.0 or 4.0 g/kg feed for 7 days. On day 7, C. coli in the feces of the CGE-treated groups were significantly lower than in the control (p < 0.01). These results suggest that CGE can be used to control C. coli in piglets.

  • Purpose : This study investigated the effects of low-intensity muscle training on neurotransmitters associated with depression and emotion regulation disorders in survivors with stroke who were diagnosed with depression or emotion regulation disorder. Methods : Survivors of chronic stroke diagnosed with depression or emotion regulation disorder (n = ) were included in the study. Concentrations of serotonin, norepinephrine, and epinephrine were measured before and after. Low-intensity muscle training was performed once a day for 50 minutes, 5 times a week for 10 weeks. Result : Levels of serotonin, norepinephrine, and epinephrine improved significantly after intervention (p < .05). Conclusion : These results confirm that low-intensity muscle training has a positive effect on neurotransmitter concentrations in survivors with stroke diagnosed with depression and emotion regulation disorders. Future studies should analyze the changes in neurotransmitters in more detail using various exercise methods and intensities to investigate their effects on depression and emotion regulation disorders.

  • Although scaling is the primary method for improving oral health, it is also associated with dental fear. The objective of this study was to empirically verify whether the use of gel anesthetic within the gingival sulcus during scaling relieves pain and improves other factors. A total of 128 patients scheduled to undergo scaling at a dental clinic of a general hospital located in the Gyeonggi Province, between July 2014 and July 2015, were enrolled in the study. The participants underwent scaling following the application of 20% benzocaine gel or placebo gel anesthetic within the gingival sulcus, and the data was collected using a questionnaire. There was a significant difference in the severity of pain, participant satisfaction, perceived sensitivity, overall discomfort, and fear of scaling between the two groups. The two groups were compared in terms of perceived need for gel anesthesia, willingness to pay for anesthesia costs, and willingness to receive scaling in the future. There were significant differences in all the three parameters depending on whether gel anesthesia was used or not. There were significant differences between the two groups in perceived sensitivity immediately after scaling and one day after scaling, with no difference seen one week after scaling. With regards to overall discomfort over time, there were significant differences between the two groups immediately after scaling. Based on these findings, we expect that application of gel anesthetic within the gingival sulcus during scaling will reduce pain, perceived sensitivity, overall discomfort, and fear of scaling with increased satisfaction.

  • Objective: The purpose of this study was to investigate whether the intrinsic foot muscle training method can improve the medial longitudinal arch in patients with chronic ankle injury and with pronated feet, as well as to investigate for the most effective exercise method for these patients. Design: Randomized controlled trial. Methods: Thirty men and women with pronated feet had participated in this study and were allocated to either the short foot exercise group (SFEG) or the towel curl exercise group (TCEG) randomly. SFEG and TCEG underwent exercises three times a week for 8 weeks, with three sets per day, totalling up to 5 minutes per day. The navicular drop test (NDT) was used in order to assess for changes in the medial longitudinal arch and the Cumberland ankle instability tool (CAIT) was used to assess for ankle instability of the chronic ankle sprain patients. Results: There was a significant increase in CAIT scores in the SFEG (p<0.05) and a significant difference between groups was presented (p<0.05). The NDT scores were significantly decreased in both groups (p<0.05). In the SFEG, the NDT scores were more decreased than in the TCEG (p<0.05). Conclusions: These results suggest that short foot exercises are more effective in providing intrinsic foot muscle training for patients with pronated feet among chronic ankle sprain patients. Furthermore, short foot exercises may be used to provide ankle stability.

  • Background: Measurement of chlorophyll fluorescence (CF) is useful for detection the ability of plants to tolerate environmental stresses such as drought, and excessive sunlight. Cnidium officinale Makino is highly sensitive to water stress and excessive sunlight. In this study, we evaluated the effect of soil water and shade treatment on the photosynthesis and leaf temperature change of C. officinale. Methods and Results: C. officinale was cultivated under uniform irrigation for 1 week drought stress (no watering) for 6 days. A significant decrease in CF was observed on the 5th day of withholding water (approximately 6% of soil water content) regardless of shading. Notably, the Rfd_lss parameter (CF decrease rates) with and without shade treatment was reduced by 73.1% and 56.5% respectively, at 6 days compared with those at the initial stage (0 day). The patterns of the degree of CF parameters corresponded to those of the soil water content and difference between leaf temperature (Ts) and air temperature (Ta). Meanwhile, CF parameters recovered to the 3 - 4 days levels after re-watering, while the soil water potential was completely restored. The suitable soil water content for C. officinale optimal growth was between -5 kPa and -10 kPa in this experiment. Conclusions: Lack of soil water in the cultivation of C. officinale, even with shading, decreased latent heat cooling through transpiration. As a result, heat dissipation declined, and the plant was subjected to drought stress. Soil water content plays a major role in photosynthesis and leaf temperature in C. officinale.
