This study was to suggest the roles of social enterprises in maintaining healthy life of the socially vulnerable by creating a customized care environment through chronic disease diet management targeting the elderly at home in need of care in the community. As for the subjects of this study, 102 in-home elderly people aged 65 or older (14 males & 88 females) who needed care in the community were provided with a diet management lunch box delivery service customized for chronic diseases. Theoretical education and cooking class on chronic diseases were provided to 15 volunteers with 10 sessions, and customized lunch boxes were provided to the elderly with chronic diseases at home on that day. In conclusion, it is believed that only by increasing the level of knowledge about chronic diseases and nutritional knowledge of the elderly will it be possible to establish a proper meal plan. Since the role of volunteers is important, it is necessary to systematically seek nutritional education methods for volunteers.

Background/Aims: This study aimed to assess the efficacy of a novel aerosol-exposure protection (AP) mask in preventing coronavirus disease in healthcare professionals during upper gastrointestinal endoscopy and to evaluate its clinical feasibility. Methods: In Study 1, three healthy volunteers volitionally coughed with and without the AP mask in a cleanroom. Microparticles were visualized and counted with a specific measurement system and compared with and without the AP mask. In Study 2, 30 patients underwent endoscopic resection with the AP mask covering the face, and the SpO2 was measured throughout the procedure. Results: In Study 1, the median number of microparticles in volunteers 1, 2, and 3 with and without the AP mask was 8.5 and 110.0, 7.0 and 51.5, and 8.0 and 95.0, respectively (p<0.01). Using the AP mask, microparticles were reduced by approximately 92%. The median distances of microparticle scattering without the AP mask were 60, 0, and 68 in volunteers 1, 2, and 3, respectively. In Study 2, the mean SpO2 was 96.3%, and desaturation occurred in three patients. Conclusion: The AP mask could provide protection from aerosol exposure and can be safely used for endoscopy in clinical practice.

Cervical cancer is the most common cancer in Laos women and a screening programme, even with the PAP smear test (PAP test), has yet to be established for routine use. The Pap test is accepted as the most appropriate for cervical cancer screening in some settings but it is not commonly available in Laos hospitals, because there are few cytopathologists and gynecologists have little experience. As a pilot program, seminars for the PAP test were given in 2007 and 2008, and then PAP tests were carried out using self-sampling instrument (Kato's device) with 200 healthy volunteers in Setthathirath hospital, Laos, in 2008. The actual examination number was 196, divided into class I 104 (53.1%), class II 85 (43.3%), class IIIa 4 (2.0%), class IIIb 1 (0.5%), and class V 1 (0.5%) by modified Papanicolau classification. Four cases had menstruation. There were 6 cases with epithelial cell abnormalities including malignancy. There were 7 cases with fungus and 2 cases with trichomonas in Class II. More than 70% volunteers felt comfortable with the Kato's device and wanted to use it next time, because of the avoidance of the embarrassment and a low cost as compared with pelvic examination by gynecologists. This first trial for PAP test for healthy Laos women related to a hospital found three percent to have abnormal cervical epithelial cells. Therefore, this appraoch using a self-sampling device suggests that it should be planned for cervical cancer prevention in Laos.

Entecavir is a potent and selective guanosine analogue that has demonstrated a significant antiviral efficacy against hepatitis B virus (HBV). The aim of this study was to evaluate the safety and pharmacokinetic profile after a single dose of entecavir 1 mg administration in Korean healthy male subjects. Eight volunteers were enrolled. After a single dose of 1 mg entecavir was orally administered, blood samples were collected at specific time intervals from 0-168 hours. The plasma concentrations of entecavir were determined by LC-MS/MS. The pharmacokinetic parameters were determined from the plasma concentration-time profiles. The mean values for $AUC_{last}$ and $AUC_{inf}$ were $14.84{\pm}7.81ng{\cdot}hr/mL$ and $20.71{\pm}8.80ng{\cdot}hr/mL$, respectively. The mean value for $C_{max}$ was $9.19{\pm}4.91ng/ml$ and median value for $t_{max}$ was 0.58 hr. No adverse events were reported by subjects or found on analysis of vital signs or laboratory tests. The results are suggested to be useful in clinical trials of entecavir in Korean subject including bioequivalence study.

Background: We evaluated the drug interaction profile of Red Ginseng (RG) with respect to the activities of major cytochrome P450 (CYP) enzymes and the drug transporter P-glycoprotein (P-gp) in healthy Korean volunteers. Methods: This article describes an open-label, crossover study. CYP probe cocktail drugs, caffeine, losartan, dextromethorphan, omeprazole, midazolam, and fexofenadine were administered before and after RG supplementation for 2 wk. Plasma samples were collected, and tolerability was assessed. Pharmacokinetic parameters were calculated, and 90% confidence intervals (CIs) of the geometric mean ratios of the parameters were determined from logarithmically transformed data using analysis of variance after RG administration versus before RG administration. Results: Fourteen healthy male participants were evaluated, none of whom were genetically defined as poor CYP2C9, 2C19, and CYP2D6 metabolizers based on genotyping. Before and after RG administration, the geometric least-square mean metabolic ratio (90% CI) was 0.870 (0.805-0.940) for caffeine to paraxanthine (CYP1A2), 0.871 (0.800-0.947) for losartan (CYP2C9) to EXP3174, 1.027 (0.938-1.123) for omeprazole (CYP2C19) to 5-hydroxyomeprazole, 1.373 (0.864-2.180) for dextromethorphan to dextrorphan (CYP2D6), and 0.824 (0.658-1.032) for midazolam (CYP3A4) to 1-hydroxymidazolam. The geometric mean ratio of the area under the curve of the last sampling time ($AUC_{last}$) for fexofenadine (P-gp) was 0.963 (0.845-1.098). Administration of concentrated RG for 2 wk weakly inhibited CYP2C9 and CYP3A4 and weakly induced CYP2D6. However, no clinically significant drug interactions were observed between RG and CYP and P-gp probe substrates. Conclusion: RG has no relevant potential to cause CYP enzyme- or P-gp-related interactions.

Due to the aging effect, older people have relatively weaker muscular performance, less range of motion in the joint articulation, and the lower sense of equilibrium than younger people. These factors attribute to their slow and clumsy ingress/egress motion. In order to analyze ingress/egress motion strategy of the elderly, healthy thirty 65 or more years old volunteers were recruited. The health condition of the each volunteer was verified by the medical checkup and also their physical capabilities were quantified by six fitness tests. Through the video analysis, older driver's ingress/egress motion strategies were classified and statistically investigated. For a comparison purpose, another thirty young volunteers also participated in the same test protocol and their ingress/egress motion strategies were also included in the statistical analysis.

The aim of this was to investigate whether the regular consumption of kimchi influences the iron status (RBC , Hb, Ht, MCH, MCV, MCHC, transferrin , serum iron, and ferritin) in volunteers. Healthy male adults(n=12) took part in the study subdivided into the control Ⅰ-phase(for 2weeks), kimchi-phase (for 4 weeks), and control Ⅱ-phase(for 2 weeks). In addition to their normal diet, participant consumed 300g of lactic acid fermented Chinese cabbage kimchi daily for four weeks. In the control Ⅰ and control Ⅱ phases, the participants kept up their normal diets without consuming any fermented foods. Dietary intakes were recorded for 3 consecutive days in each phase, with the aid of household measures. Every two weeks. blood specimens were analysed. Significant differences(p<0.05) between the phases were found in MCHC, and transferrin in blood were not significantly changed during kimchi consumption. However, serum iron and ferritin levels were significantly increased(p<0.05) during kimchi consumption, achieving the highest levels in the fourth week of the kimchi components(ascrobic acid, sulfer compound, organic acid, capsaicin, gingerol , allicin). Because of lacticacid fermented kimchi's potential to prevent anemia , the consumption of this food can be recommended.

The effect of cimetidine on the pbarmacokinetic parameters of cyclosporine (intravenous administration) were determined in 6 healthy volunteers (22-48 years old, 48-62 kg) by cross-over design. Cyclosporine and cyclosporine metabolites in whole blood were analysed by fluororescence polarization immunoassay (TDx-FLX). The blood concentrations of cyclosporine After pretreatment with cimetidine (200 mg bid, for 3days) were increased significantly at 8-12 hrs compared to the control (p<0.05). The ratios of blood concentrations of cyclosporine metabolites (M1, M17) to parent drug were decreased significantly at 8-12 hrs (p<0.05). Total body clearance (CL) was also decreased significantly (p<0.05), and area under the curve $(AUC,\%)$ was increased but not significant.

To follow the metabolic fate of aglycone of ginseng saponins,in vitro and in vivo experiments were performed. Incubation of 20(S)-prtopanaxatriol (1) with rat liver S9 fraction afforded unique ocotillol derivatives, 20, 24-epoxysides (3 and 4). Also 20(S)-prtopanaxadiol (2) gave the corresponding epoxides (5). Healthy volunteers were taken with Sanchi Ginseng, which contains protopanaxatriol and protopanaxadiol saponins and no ocotillol saponins. From the alkaline hydrolysate of the urine samples of these volunteers,3 was detected as well as 1, and the ratio of 3/1 increased up to 2.0 at the maximum at 50 hrs. Biochemical significance of the ocotillol derivatives is discussed, since the main bioactive saponin in Panax vietnamensis is an ocotillol-type saponin, majonoside R2 (7).

Objective: ⁶⁸Ga-NGUL is a novel prostate-specific membrane antigen (PSMA)-targeting tracer based on Glu-Urea-Lys derivatives conjugated to a 1,4,7-triazacyclononane-N,N',N''-triacetic acid (NOTA) chelator via a thiourea-type short linker. This phase I clinical trial of ⁶⁸Ga-NGUL was conducted to evaluate the safety and radiation dosimetry of ⁶⁸Ga-NGUL in healthy volunteers and the lesion detection rate of ⁶⁸Ga-NGUL in patients with prostate cancer. Materials and Methods: We designed a prospective, open-label, single-arm clinical trial with two cohorts comprising six healthy adult men and six patients with metastatic prostate cancer. Safety and blood test-based toxicities were monitored throughout the study. PET/CT scans were acquired at multiple time points after administering ⁶⁸Ga-NGUL (2 MBq/kg; 96-165 MBq). In healthy adults, absorbed organ doses and effective doses were calculated using the OLINDA/EXM software. In patients with prostate cancer, the rates of detecting suspicious lesions by ⁶⁸Ga-NGUL PET/CT and conventional imaging (CT and bone scintigraphy) during the screening period, within one month after recruitment, were compared. Results: All 12 participants (six healthy adults aged 31-32 years and six prostate cancer patients aged 57-81 years) completed the clinical trial. No drug-related adverse events were observed. In the healthy adult group, ⁶⁸Ga-NGUL was rapidly distributed, with the highest uptake in the kidneys. The median effective dose coefficient was calculated as 0.025 mSv/MBq, and cumulative activity in the bladder had the highest contribution. In patients with metastatic prostate cancer, 229 suspicious lesions were detected using either ⁶⁸Ga-NGUL PET/CT or conventional imaging. Among them, ⁶⁸Ga-NGUL PET/CT detected 199 (86.9%) lesions and CT or bone scintigraphy detected 114 (49.8%) lesions. Conclusion: ⁶⁸Ga-NGUL can be safely applied clinically and has shown a higher detection rate for the localization of metastatic lesions in prostate cancer than conventional imaging. Therefore, ⁶⁸Ga-NGUL is a valuable option for prostate cancer imaging.
