  • Helminthological parasites for inhabitants in Boeun-Gun, Chungbuk province were survyed. Total infection rate was 21.4% and helminth ova of-seven species were observed: Clonorchis sinensis 11.7%, Metagonimus sp. 7.0%, Echinostoma hortense 2.7%, Taenia sp. 2.3%, Ascaris lumbri-coides 0.8%, Trichuris trichiura 1.6% and Enterobius vermicularis 3.5%. Infection rate of food-transmitted helminths (C. sinensis, Metagonimus sp. E.hortense, Taenia sp.) was 76.4% (42/55), soil-transmitted helminths (A.lumbricoides, T. trichiura) was 7.3% (4/55), contageous helminths(E. vermicularis) was 16.3% (9/55). Multiple infection rate was 30.9% and most of them were limited in snail-transmitted helminths(C.sinensis, Melagonimas sp., E. hortense). Infection rate of male (18. 3%) was higher than those of female (3.1%). Intensities of C.sinensis and Metagonimus sp. were light or moderate, showed 530 and 444 by mean E.P.G. respectively. In this survey, we newly found the small endemic areas of E.hortense, which was previously reported sporadically in Korea other than in Chungbuk province.

  • To understand the cytotoxic mechanism of $MPP^+,$ we examined the involvement of ceramide in $MPP^+-induced$ cytotoxicity to human neuroblastoma SH-SY5Y cells. When SH-SY5Y cells were exposed to $MPP^+,\;MPP^+$ induced dose-dependent cytotoxicity accompanied by 2-fold elevation of intracellular ceramide levels in SH-SY5Y cells. Three methods were used to test the hypothesis that the elevated intracellular ceramide is related to $MPP^+-induced$ cytotoxicity: $C_2-ceramide$ was directly applied to cells, sphingomyelinase (SMase) was exogenously added, and oleoylethanolamine (OE) was used to inhibit degradation of ceramide. Furthermore, inhibition of ceramide-activated protein phosphatase (CAPP), the effector of ceramide, using okadaic acid (OA) attenuated cell death but treatment of fumonisin $B_1,$ the ceramide synthase inhibitor, did not alter the cytotoxic effect of $MPP^+.$ Based on these, we suggest that the elevation of intracellular ceramide is one of the important mediators in $MPP^+-induced$ cell death.

  • Purpose: The purposes of this study were to develop a navigation program for newly diagnosed cancer patients and to evaluate its effects. Methods: The navigation program was based upon Professional Navigation Framework. Patients were asked to complete self-administered questionnaires on satisfaction, distress, anxiety and depression for evaluating the program. Results: The navigation program consisted of facilitating two concepts: continuity of care and empowerment of patients. Information-education package, telephone counseling and navigator's phone number were provided to the newly diagnosed cancer patients for care continuity. Self-care diary and emotional support by telephone counseling were provided to the patients for empowerment of patients. A total of 163 patients - 78 control and 85 experimental participants - were included in the study. The mean scores of satisfaction, distress, anxiety and depression had no statistical differences between the two groups after program implementation. In patients with longer waiting days, the experimental group with the navigation program showed higher relational continuity than the control group after program implementation(p=.023). In patients with longer waiting days or with higher distress, satisfaction of relational continuity was improved after program implementation in the experimental group. Conclusion: The navigation program in this study has applied the concept of patient navigation into oncology clinical setting in Korea. Navigation program can play a significant role in assisting patients navigating across the care continuum.

  • Background : Previous studies have suggested a lack of complete cross-resistance between steroidal (exemestane) and non-steroidal aromatase inhibitors (nSAI). Methods : Eighty-eight metastatic breast cancer (MBC) patients who received 25 mg of exemestane orally once a day at the National Cancer Center, Korea, between 2003 and 2009, were reviewed retrospectively. All patients had received nSAI for metastatic disease prior to exemestane therapy. Results : The median age was 52 years (range, 33-79), and 13 (14.8%) patients were premenopausal who concomitantly received GnRH agonist. Exemestane was given as a second- (80.7%) or third-line (19.3%) hormone therapy. The clinical benefit (CB) rate (complete response + partial response + stable disease ${\geq}$ 24 weeks) was 30.7%, with a median CB duration of 10.0 months (range, 6.3-78.7). The median progression-free survival (PFS) was 3.0 months (95% confidence interval [CI], 1.99-4.01) and the overall survival (OS) 21.5 months (95% CI, 17.96-25.04), with a median followup of 50.3 months. Patients who achieved CB had longer OS than those patients who did not (29.6 vs 17.9 months; P=0.002). On univariate analysis of predictive factors, patients who had achieved CB from previous nSAI tended to show lower CB rate (24.6% vs 44.4%, respectively; P=0.063) and shorter PFS (2.8 vs 4.8 months, respectively; p=0.233) than patients who had not. Achieving CB from previous nSAI became independent predictive factor for CBR to exemestane on multivariable analysis (Odds ratio = 2.852, P = 0.040). Conclusions : Exemestane after nSAI failure was effective in prolonging CB duration. The drug's efficacy seemed to be inferior in patients who had benefit from previous nSAI use.

  • Objectives : The aim of this study was to report the effect of Korean medical therapy on pain and dysfunction after anterior cruciate ligament (ACL) reconstruction. Methods : A 25-year-old man experienced severe pain after right ACL reconstruction surgery. He received Korean medical treatments such as acupuncture, herbal medicine, and physiotherapy from July 10, 2014 to August 2, 2014. Results : After the treatments, his visual analogue scale scores generally decreased and the range of motion of the right knee improved from $0^{\circ}$ to $90^{\circ}$. Furthermore, the Knee Infury and Osteoarthritis Outcome Score increased from 99 to 142. Conclusion : The findings suggest that Korean medical treatments might be effectively used to treat pain and dysfunction after soft-tissue surgeries such as ACL reconstruction. Nevertheless, further research is warranted because of the limited sample size of this study.

  • BACKGROUND/OBJECTIVES: We investigated the effects of a combination of grape pomace (Vitis labrusca, Campbell Early) and Omija fruit (Schizandra chinensis, Baillon) ethanol extracts on lipid metabolism and antioxidant defense system in diet-induced obese mice. MATERIALS/METHODS: Forty male C57BL/6J mice were divided into four groups and fed high-fat diet (control group, CON) or high-fat diet added 0.5% grape pomace extract (GPE), 0.05% Omija fruit extract (OFE) or 0.5% GPE plus 0.05% OFE (GPE+OFE) for 12 weeks. RESULTS: In contrast to the GPE- or OFE-supplemented groups, the GPE+OFE group showed significantly lower body weight and white adipose tissue weights than the CON group. Moreover, GPE+OFE supplementation significantly decreased plasma total cholesterol and increased the plasma HDL-cholesterol/total-cholesterol ratio (HTR) compared to the control diet. The hepatic triglyceride level was significantly lower in the GPE+OFE and GPE groups by increasing ${\beta}$-oxidation and decreasing lipogenic enzyme compared to the CON group. Furthermore, GPE+OFE supplementation significantly increased antioxidant enzyme activities with a simultaneous decrease in liver $H_2O_2$ content compared to the control diet. CONCLUSIONS: Together our results suggest that supplementation with the GPE+OFE mixture may be more effective in improving adiposity, lipid metabolism and oxidative stress in high-fat diet-fed mice than those with GPE and OFE alone.
