Purpose: The purpose of this study was to determine the preventive effect of joint mobilization on biphasic pain response induced formalin test. Methods: Sprague-dawley rats(n=30) were ramdomly divided into the control group without intervention, sham control group with application of hand contact without mobilization, joint mobilization group with application of hand contact with mobilization. Joint mobilization of knee procedure involved an grade III extension mobilization basically with anterior-posterior gliding of the tibia on the femur. Formalin injection caused biphasic pain response which is lated for 60 minute. The first phase result from primary afferent sensory fiber, wheareas the second phase has been proposed to central sensitization in the central nervous system. Behavioral analysis was performed by digital camera after 5% formalin subcutaneous injection into the dorsal foot. Results: Pain response of joint mobilization group show significant lower than control gorup and sham control group. Conclusion: This result suggest that pre-application of joint mobilization may be effective intervention to prevent the formalin induced pain.

c-Fos is known to related to synaptic plasticity and apoptosis in damage from ischemia or external injury. The purpose of this study was to investigate whether needle electrode electrical stimulation(NEES) is effective in increasing the number of c-Fos response cells and c-Fos expression in striatum after global ischemia in rats. There were no treatment and occlusion in the control group, global ischemia(GI) group were no treatment after carotid artery occlusion, and needle electrode electrical stimulation(NEES) group were treated with NEES after GI induced. The number of striatum c-Fos response cells and c-Fos protein expression significantly decreased in the NEES group compared to the GI group after 12, 24, 48 hours. The results of the present study suggest that NEES is ineffective in improving global ischemia in rats and may also be ineffective in the globally ischemic human brain.

Purpose: This retrospective study assessed the effectiveness of submucosal (SM) midazolam (M), oral chloral hydrate (CH), hydroxyzine (H), and nitrous oxide (N) 99 uncooperative pediatric dental patients over 182 sedation sessions. Methods: Selection criteria included good medical health (ASA I), from 2 to 6 years of age, uncooperative behavior, and the need for restorations and dental surgery. The children who was administerated with CH H, N was Group 1 (48 case). The children who was administerated with CH, H, N, M was Group 2 (51 case). All the patients received oral CH (50-70 mg/Kg), H (1 mg/Kg) and N (less than 50%). Additionally the Group 2 received SM midazolam (0.1-0.2 mg/kg). Behavior response was rated as quiet (Q), crying (C), movement (M), or struggling (S) every 5 minutes through operative procedures. Behavior response rating was assigned to Houpt scale of Overall behavior. Data was analyzed using Chi-Square Test. Results: The Group 2 had more effective (88.2%) than the Group 1 (68.8%)(P = 0.05). Also, vomiting response decreased in the Group 2 (94.4%) than those with oral administration of chloral hydrate alone without SM midazolam (77.1%)(P = 0.05). Conclusions: SM midazolam improved the quality of sedation and vomiting response.
This study investigated the effects of chromium propionate on growth performance, serum traits and immune response in weaned pigs. Twenty-four 4 wk-old crossbred weanling pigs (initial body weight about 9.52${\pm}$0.48 kg) were randomly allotted into one of two groups, a control group (basal diet), chromium propionate group (diet supplemented with 200 ${\mu}g$$kg^{-1}$ (ppb) of chromium propionate). This experiment was conducted over nine weeks. Escherichia coli lipopolysaccharide (LPS) 100 ${\mu}g$$kg^{-1}$ BW was used as the stress-inducing agent in the middle (4 wks) and final (8 wks) periods. The experimental results indicated that chromium propionate had no effect on growth performance (p>0.05). Chromium propionate supplementation reduced the percentage of LDL+VLDL (low and very low-density lipoprotein) and increased HDL (high-density lipoprotein), but did not affect other serum traits. Pigs supplemented with chromium propionate had higher antibody titers specific for sheep red blood cells (SRBC) and serum total globulin relative to the control during the final period (p<0.05). A challenge with LPS increased white blood cells in the chromium propionate group in both experimental periods (p<0.05). The chromium propionate group exhibited higher IgG and $\gamma$-globulin than the control during the middle experimental period (p<0.05). Moreover, the PHA (phytohemagglutinin) challenge result in the chromium propionate group was better than the control group (p=0.056). Greater neutrophil activity was displayed than in the control (p<0.05). This suggests that chromium propionate supplementation benefited the weaned pigs in lipoprotein and immune response.

The purpose of this study was to identify the effects of a hands-on training regarding maritime safety including abandon ship and fire-fighting as related to sea survival, fire-fighting knowledge and emergency response leadership in seafarers engaged on a seagoing ship. The study was conducted with a nonequivalent control group pre-posttest design. Two hundred-sixty-six participants were assigned to either the experimental group(128) or control group(138). The hands-on training regarding maritime safety included sea survival and fire fighting drill, and it was implemented with the experimental group for two days from July 1, 2015 to June 30, 2016. Data was analyzed using chi-square, t-test and ANCOVA by using IBM SPSS Statistics(version 24) program. The experimental group who had the hands-on training showed significantly higher sea survival knowledge(F=902.32, p<.001), shipboard fire-fighting knowledge(F=1013.76, p<.001) and emergency response leadership(F=1802.62, p<.001) for maritime safety compared with the control group who had traditional education. The results indicate that a hands-on training is an effective teaching method to improve sea survival, fire-fighting knowledge and emergency response leadership in seafarers engaged. Further study is needed to identify the effect of a hands-on training regarding maritime safety according to the environmental changes of seafarers.

The interlayers, either softer or stiffer than the surrounding layers, are usually overlooked during field investigation due to the small thickness. They may be neglected through the analysis process for simplicity. However, they may significantly affect the dynamic behavior of the soil-foundation system. In this study, a series of 3D finite-element Direct-solution steady-state harmonic analyses were carried out using ABAQUS/CAE software to investigate the impacts of interlayers on the dynamic response of a cast in place pile group subjected to horizontal harmonic load. The experimental data of a 3×2 pile group testing was used to verify the numerical modeling. The effects of thickness, depth, and shear modulus of the interlayers on the dynamic response of the pile group are investigated. The simulations were conducted on both stiff and soft soils. It was found that the soft interlayers affect the frequency-amplitude curve of the system only in frequencies higher than 70% of the resonant frequency of the base soil. While, the effect of stiff interlayer in soft base soil started at frequency of 35% of the resonant frequency of the base soil. Also, it was observed that a shallow stiff interlayer increased the resonant amplitude by 11%, while a deep one only increased the resonant frequency by 7%. Moreover, a shallow soft interlayer increased the resonant frequency by 20% in soft base soils, whereas, it had an effect as low as 6% on resonant amplitude. Also, the results showed that deep soft interlayers increased the resonant amplitude by 17 to 20% in both soft and stiff base soils due to a reduction in lateral support of the piles. In the cases of deep thick, soft interlayers, the resonant frequency reduced significantly, i.e., 16 to 20%. It was found that the stiff interlayers were most effective on the amplitude and frequency of the pile group.
This study investigated the effect of enteral nutrition supplementation on glucose and lipid metabolism in non-insulin dependent diabetes mellitus(NIDDM) patients(n=29). Nutrition formula(400kcal/day) were supplied daily for eight weeks as a substitute for a snack or a meal. Subjects were divided into three groups based on changes of fasting blood glucose(FBG), glucose response area(GRA) on oral glucose tolerance test(OGTT), before and after intake of nutrition formula : group 1(the group of a decrease in FBG and GRA, n=20), group 2(the group of a decrease in FBG and an increase in GRA, n=4), and group 3(the group of an increase in FBF and GRA, n=5). Before nutrition supplementation, group 3 showed a longer tendency of DM duration and a lower tendency of insulin and C-peptide response are than those of group 1 and 2. At 8 weeks after nutrition supplementation, group 1 showed a significant increase in insulin and C-peptide response areas but group 2 and 3 showed no change in those areas. After nutrition supplementation, all three groups showed a tendency of decrease in glycated hemoglobin and no significant changes in the levels of serum triglycerides, HDL, LDL, total cholesterol, albumin, transferrin, creatinine, GOT and GPT. The results suggest that using an enteral nutrition formula in NIDDM patients is a good substitute for a meal or snack and could improve blood glucose control without any changes in lipid levels, and liver and kidney functions. The beneficial effect of nutrition supplementation on glycemic control resulted from components of nutrition formula had such as additional fiber and high monounsaturated fatty acid as the source of fat to be helpful 세 glycemic control in diabetics.

In order to investigate the effect of Sojagangki-tang on imuno-activity. the author performaed this experimental study. Delayed type hypersensitivity (DTH) and rosette forming cells (RFC) for cell-mediated immune response, hemagglutinin (HA) titers, hemolysin (HL) titers for humoral immune response, Carbon clearance for phagocytic function of MPS (mononuclear phagocyte system) were measured in ICR mice. The results were summurized as follows: Delayed tape hypersensitivity was increased with statistical significance in the administrated solid extract of Sojagangki-tang treated group as compared with the control group. Hemagglutinin titers were increased with statistical significance in the administrated solid extract of Sojagangki-tang treated group as compared with the control group. Hemolysin titers were increased with statistical significance in the administrated solid extract of Sojagangki-tang treated group as compared with the control group. Number of RFC was increased with statistical significance in the administrated solid extract of Sojagangki-tang treated group as compared with the control group. Carbon clearance was increased with statistical significance in the administrated solid extract of Sojagangki-tang treated group as compared with the control group. Through in vivo experimental study in ICR mice Sojagangki-tang enhences the cell-mediated immmune response, the humoral immune respose. According to the above results, I think that Sojagangki-tang could be used for allergy asthma and lung damage patients.
Background: This study aimed to examine the effect of Scutellaria baicalensis extract (SBE) on ameliorating pain response and inflammation in an animal model. Methods: The effects of SBE on joint inflammation-induced rats and pain writhing response were measured. In rats with monosodium iodoacetate (MIA)-induced knee osteoarthritis (OA), the weight-bearing distribution of the hind legs was measured, the actual joint condition was visually confirmed, and serum cytokines were extracted from whole blood and measured. In addition, the acetic acid-induced pain was measured by the number of abdominal wall contractions and writhing responses. Results: 1. The weight-bearing distribution of the hind limbs of the SBE group was remarkably improved compared with that of the control group 7 days after MIA treatment, and the SBE 300 group was improved similarly to that of the indomethacin group. 2. Cartilage erosion was significantly recovered in the SBE and indomethacin groups, and the degree of healing of cartilage erosion by SBE was similar to that by indomethacin. 3. The serum levels of cytokines interleukin-1β, tumor necrosis factor-α, and interleukin-6 were significantly decreased in the SBE group compared with that in the control group, and the SBE 300 group had reduced levels of cytokines similar to the indomethacin group. 4. As regards acetic acid-induced writhing response, the number of writhes was significantly reduced in the SBE and ibuprofen groups, and the SBE 600 group had fewer writhes than the ibuprofen group. Conclusion: SBE significantly improves knee OA and pain and is expected to show similar therapeutic effects to indomethacin and ibuprofen.

Purpose: The purpose of this study was to investigate the predictable value of pretreatment $^{18}F$-fluorodeoxyglucose positron emission tomography-computed tomography ($^{18}F$-FDG PET-CT) in radiotherapy (RT) for patients with hepatocellular carcinoma (HCC) or portal vein tumor thrombosis (PVTT). Materials and Methods: We conducted a retrospective analysis of 36 stage I-IV HCC patients treated with RT. $^{18}F$-FDG PET-CT was performed before RT. Treatment target was determined HCC or PVTT lesions by treatment aim. They were irradiated at a median prescription dose of 50 Gy. The response was evaluated within 3 months after completion of RT using the Response Evaluation Criteria in Solid Tumors (RECIST). Response rate, overall survival (OS), and the pattern of failure (POF) were analyzed. Results: The response rate was 61.1%. The statistically significant prognostic factor affecting response in RT field was maximal standardized uptake value (maxSUV) only. The high SUV group (maxSUV ${\geq}5.1$) showed the better radiologic response than the low SUV group (maxSUV < 5.1). The median OS were 996.0 days in definitive group and 144.0 days in palliative group. Factors affecting OS were the %reduction of alpha-fetoprotein (AFP) level in the definitive group and Child-Pugh class in the palliative group. To predict the POF, maxSUV based on the cutoff value of 5.1 was the only significant factor in distant metastasis group. Conclusion: The results of this study suggest that the maxSUV of $^{18}F$-FDG PET-CT may be a prognostic factor for treatment outcome and the POF after RT. A %reduction of AFP level and Child-Pugh class could be used to predict OS in HCC.
