Objectives: Boeum-jeon (BEJ) is a herbal formula composed 8 Korean medicinal herbs and is traditionally used to treat inflammatory diseases. In this study, the authors tried to confirm the antioxidant efficacy of BEJ and its anti-inflammatory effect in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Methods: In this experiment, results of BEJ on the following two were measured as follows: (1) Antioxidant effects was measured by DPPH Radical scavenging Activity, ABTS Radical scavenging Activity. (2) Anti-Inflammatory effects were evaluated by the production amount of ROS, NO, Cytokine (PGE2, IL-1β, IL-6, TNF-α), COX-2, iNOS, TNF-α, IL-1β, IL-6, HO-1, NQO1 (the previous seven are "mRNA Expression"), COX-2, iNOS, TNF-α, IL-1β, IL-6, HO-1, NQO1, NRF2 (the previous eight are "Protein Expression") ERK, JNK, p38 (the previous three are "Protein Phosphorylation") in LPS-stimulated RAW 264.7 cells. Results: The experimental measurement results are as follows: (1) DPPH Radical scavenging Activity, ABTS Radical scavenging Activity increased in a concentration -dependent manner in the BEJ-treated group. (2) As a result of measuring anti-inflammatory efficacy, the production of ROS, NO, and Cytokine (PGE2, TNF-α, IL-1β, IL-6) in the BEJ-administered group was significantly reduced compared to the control group. (3) Among mRNA Expression levels, COX-2, iNOS, IL-1β, IL-6 and TNF-α was significantly decreased in a concentration-dependent manner than in the control group, and HO-1 and NQO1 were significantly increased in a concentration -dependent manner than in the control group. (4) Among the Protein Expression levels, COX-2, iNOS, IL-1β, IL-6 and TNF-α was significantly decreased in a concentration -dependent manner compared to the control group, and HO-1, NQO1 and NRF2 was significantly increased in a concentration-dependent manner compared to the control group. (5) As a result of Protein Phosphorylation, ERK, p38 and JNK was significantly decreased compared to the control group in a concentration-dependent manner. Conclusions: Boeum-jeon has been experimentally confirmed to have antioxidant and anti-inflammatory effects, and if the evidence for efficacy is reinforced through further studies such as in vivo studies and clinical trials in the future, it can be effectively used to treat various inflammatory diseases such as bladder inflammation and chronic pelvic inflammation.

Objectives: To obtain audiologic basic data to diagnose the noise induced hearing loss of workers in fisheries. Methods: The charts of the referred fishermen with noise induced hearing loss from November 2022 to February 2023 at a general hospital were retrospectively reviewed. Pure tone audiometry, speech audiometry, auditory brainstem response test and auditory steady state response test were conducted. Results: All of them were men over 60 years of age, and the average duration of exposure to noise was 38.9 ± 10.8 years, and the average symptom duration of hearing loss was 13.4 ± 4.3 years. Although the hearing thresholds in the high frequencies were higher than thresholds in the low frequencies, the audiogram showed a down-sloping pattern without rebound at 8 kHz. 10.5% of the cases had thresholds greater than 75 dB in high frequencies, but 57.9% had thresholds greater than 40 dB in low frequencies. Other hearing test results of fishermen were similar to those of general noise-induced hearing loss. Conclusions: Although the fishermen were exposed to noise for a long time, they recognized hearing loss late. The hearing threshold in lower frequencies of the fishermen was higher than expected. Further studies will be needed to analyze the audiologic characteristics of noise-induced hearing loss of the fishermen after confirming noise exposure by conducting a survey on the working environment, such as the noise level and working hours.

Purpose: We investigated the effect of open tray impression using pick-up impression coping and close tray impression using transfer impression coping on the accuracy of impression in edentulous patients on their mandibular parts. the effect of material types of pick-up type impression copings for splinting in open tray impression on the accuracy of impression was also evaluated. Materials and Methods: Two implant fixtures were implanted in parallel in the left molar of the mandibular in the shape of a mandibular partial edentulous model. The 40 individual trays were fabricated using 3D printer. The prepared individual trays were classified into 4 groups (i.e., PN, PG, PH, and TN groups), and a total of 40 impression-takings were conducted. A master cast was connected to a Scan Body. The converted STL file was super-imposed on the scan images of the various groups. Results: The order of standard deviation values decreased as follows: PN (0.2343 ± 0.0844 mm), TN (0.2192 ± 0.0840 mm), indicating that the high accuracy of impression for TN group. In addition, for the comparison results between the material types used in splinting the open tray impression, the PH group showed a relatively lower standard deviation (0.1910 ± 0.1176 mm) than that of the PN group (0.2343 ± 0.0844 mm), PG group (0.2556 ± 0.1082 mm). Conclusion: The acrylic resin synthesized by light-induced polymerization exhibited a higher accuracy of impression taking than that of autopolymerizing acrylic resin. Meanwhile, the accuracy of impression taking was not dependent on the implant impression taking method or the presence of connection/fixation of impression copings.

Purpose: In the past, detection of metabolic abnormalities in plasma amino acid (PAA) and urine organic acid (UOA) has been widely used to diagnose clinical mitochondrial diseases, such as mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS). In this study, the diagnostic values of PAA and UOA were reviewed, and their effectiveness in the diagnosis of MELAS was examined retrospectively. Methods: Blood and urine samples at the time of diagnosis were collected from all clinically diagnosed MELAS patients (n=31), and PAA and UOA tests were performed. All samples were collected in a fasting state to minimize artifacts in the results. The difference in the ratio of abnormal metabolites of PAA and UOA at initial diagnosis was statistically compared between the MELAS with genetic confirmation (n=19, m.3243A>G mutation) and MELAS without genetic confirmation (n=12) groups. The MELAS without genetic confirmation group was used as control. Results: Comparison of PAA and UOA between the two groups revealed that no abnormal metabolites showed characteristic differences between gene-confirmed MELAS patients with and those without genetic confirmation. Conclusions: Abnormal values of metabolites in PAA or UOA might be useful as a screening test but are not sufficient to diagnose MELAS patients.

Objective: This study aimed to assess the safety and effect on glucose level of Bojungikgi-tang in patients with type 2 diabetes mellitus. Methods: To review patients' clinical characteristics and laboratory tests retrospectively, we investigated 15 hospitalized patients with type 2 diabetes mellitus who took Bojungikgi-tang at Kyung Hee University Korean Medical Hospital for at least one day between January 2012 and December 2022. The blood glucose levels, including fasting blood sugar (FBS), 2-hour postprandial glucose (PP2) levels, and glycated hemoglobin level, were collected to determine the effect of the Bojungikgi-tang on blood sugar changes. Furthermore, to evaluate the safety of Bojungikgi-tang, hepatic function and renal function tests were implemented, including aspartate aminotransferase, alanine aminotransferase, alkaline phosphatase, γ-glutamyltransferase, blood urea nitrogen, creatinine, and Modification of Diet in Renal Disease estimated glomerular filtration rate. Results: When Bojungikgi-tang and a standard treatment for diabetes were administered for patients with type 2 diabetes, it was confirmed that there were no statistically significant changes in FBS and PP2 levels in the analysis of each medication taken. There was no significant difference in the safety profile after taking Bojungikgi-tang. Conclusions: The combined administration of Bojungikgi-tang with standard hypoglycemic medication for patients with type 2 diabetes may not affect blood glucose levels and safety.

Purpose. The aim of this study was to evaluate the proximal contact with a dental floss compared to a celluloid strip and a metal strip in normal dental arch and investigate what the most effective method for measuring is. Materials and methods. The subjects of this study was consisted with 20 healthy adults (10 males and 10 females) who had normal dentition. A dentist with more than 5 years of clinical experience evaluated the proximal contacts using a dental floss method, a celluloid strip method, and a metal strip method. Statistical analysis were performed by the use of Mann-Whitney U test. A P-value < .05 was considered statistically significant in all analysis. In addition, in the evaluation of proximal contact using a dental floss, the measurement of proximal contact using a celluloid strip and a metal strip was compared. Results. 80 % of all proximal contact was proper. Proper proximal contact was observed at the posterior area compared to the anterior area (P < .05). And male had proper proximal contact at the anterior area, female had proper proximal contact at the posterior area (P < .05). The consistency analysis between the results of the celluloid strip and the metal strip experiment on the results obtained from the floss using the consistency scale Kappa index shows that using celluloid strip is more advantageous than using the metal strip. Conclusion. Only 80% of all proximal contact was proper. Using celluloid strips with various thickness for evaluating of proximal contact is considered to be helpful for accurate measuring of proximal contact.

Patients with neurocognitive disorder show behavioral psychological symptoms such as agitation, aggression, depression, and wandering, as well as cognitive decline, which puts a considerable burden on patients and their families. For the treatment of behavioral psychological symptoms, patient-centered, non-pharmacological treatment should be used as a first line approach. This paper describes non-pharmacological interventions to manage and treat behavioral psychological symptoms in patients with neurocognitive disorder. In order to control behavioral psychological symptoms such as agitation, depression, apathy, insomnia, and wandering, it is important to identify and evaluate factors such as environmental changes and drugs, and then solve such problems. Non-pharmacological interventions include reassurance, encourage, distraction, and environmental change. It is necessary to understand behavior from a patient's point of view and to approach the patient's needs and abilities appropriately. Reminiscence therapy, music therapy, aroma therapy, multisensory stimulation therapy, exercise therapy, light therapy, massage therapy, cognitive intervention therapy, and pet therapy are used as non-pharmacological interventions, and these approaches are known to improve symptoms such as depression, apathy, agitation, aggression, anxiety, wandering, and insomnia. However, the quality of the evidence base for non-pharmacological approaches is generally lower than for pharmacological treatments. Therefore, more extensive and accurate effectiveness verification studies are needed in the future.

Objectives: This study analyzed an online survey targeting women and Korean medicine doctors who participated in the Yeosu City Postpartum Health Center Support Project. Through this, we would like to discuss the direction of support for postpartum health care support projects and new policies to encourage childbirth. Methods: In this study, we examined the results of an online survey from 73 women and 29 Korean medicine doctors. We examined 39 items, including basic information, childbirth-related items, Korean medicine treatment-related items, business satisfaction, and policies, answered by 73 women and 29 Korean medicine doctors who responded to the online survey. Results: The average age of women was 33.62±4.19 years, and the average age of Korean medicine doctors was 49.82±8.60 years. Musculoskeletal pain appeared most commonly in both maternal and Korean medicine doctors' online surveys. The visit date from the date of delivery was 36.87±27.06 days. Gungguijohyeol-um and Boheo-tang were widely used. The survey score of women whose main symptoms improved after taking herbal medicine was 3.04±1.15 points, and the survey score of Korean medical doctors was 4.13±0.74 points. The positive response to the policy was 73.7% for satisfaction with the overall policy to encourage childbirth, 54.8% for perceived support, and 65.7% for reduction of economic burden. Conclusions: Women who participated in the postpartum health care support project and received Korean medicine treatment and Korean medicine doctors who performed Korean medicine treatment were very satisfied. The most frequent postpartum symptom was musculoskeletal pain. The degree of improvement in main symptoms after taking herbal medicine was higher among Korean medicine doctors than among women. Among childbirth policies, the areas that should be prioritized are childbirth support projects and postpartum care projects.

Purpose To evaluate the ability of the Hounsfield unit (HU) measurement of the femoral neck during multidetector computed tomography (MDCT) for assessing osteoporosis compared with dual-energy X-ray absorptiometry (DXA). Materials and Methods Forty-two patients with femoral neck fractures who underwent MDCT and DXA from July to December 2016 were included in this study. HU measurements were made of the cancellous portions of the normal contralateral femoral neck on MDCT. Bone mineral density (BMD) and T-scores were obtained at the femur DXA. Correlations of HU values with BMD and T-scores were analyzed using Spearman's correlation test. Results The mean BMD and T-score of the femoral neck were 0.650 g/cm² and -2.4, respectively. The mean HU values for the normal, osteopenia, and osteoporosis groups were 131.9, 98.9, and 41.3, respectively. HU values at the femoral neck were positively correlated with BMD (r² = 0.670; p < 0.001) and T-scores (r² = 0.676; p < 0.001). Conclusion The HU values of the femoral neck on MDCT are significantly correlated with BMD and T-scores of femur DXA. The HU values may serve as a diagnostic tool for the screening of regional bone quality when MDCT is performed for other reasons.
