Objectives: This study was designed to investigate anti-obesity effects the improvement effects of Gyejibongnyeong-hwan and Gyejibongnyeong-hwan-Gangji-hwan (CIPPDF) in a ob/ob mouse model. Methods: Seven-week old mice (wild-type C57BL/6J and ob/ob) were used for all experiments. Wild-type C57BL/6J mice were used as normal group and obese ob/ob mice were randomly divided into 4 groups. a normal group given a standard diet, an obese control group given a standard diet with CIPP (300 mg/kg), CIPPDF (1) (300+300 mg/kg), CIPPDF (2) (300+600 mg/kg) respectively. After 10 weeks of treatment, body weight gain, feeding efficiency ratio, blood lipid markers, mRNA levels of genes involved in fatty acid ${\beta}-oxidation$ and lipogenesis in in-vivo, were examined. Results: 1. Body weight gain and Feeding efficiency ratio were significantly decreased in CIPPDF (1) compared with control. Fat mass was significantly decreased in CIPPDF (2) in EAT compared with control. 2. Consistent their effects on body weight gain and fat mass, circulating concentrations of LDL-cholesterol were decreased in CIPPDF (1), CIPPDF (2) groups compared with control. 3. MCAD mRNA levels of genes was increased in CIPPDF (1), CIPPDF (2) groups in the liver, epididymal adipose tissue compared with control. VLCAD mRNA levels of genes was increased in CIPPDF (1), CIPPDF (2) groups in the skeletal muscle compared with control. 4. $PPAR{\gamma}$ mRNA was decreased in CIPPDF (1) in the liver compared with control. SCD1 mRNA was decreased in CIPPDF (1), CIPPDF (2) groups in the epididymal adipose tissue compared with control. Conclusions: In conclusion, These results suggest that CIPPDF not only decrease feeding efficiency ratio, and LDL-cholesterol, but also reduce EAT fat mass contributing to the improvement of ovesity. CIPPDF also were increased in mRNA levels of genes involved in fatty acid ${\beta}-oxidation$ and decreased in mRNA levels of genes involved in lipogenesis.

In order to understand the renal reabsorption mechanism of neutral amino acids via amino acid transporters, we have isolated human L-type amino acid transporter 2 (hLAT2) and human T-type amino acid transporter 1 (hTAT1) in human, then, we have examined and compared the gene structures, the functional characterizations and the localization in human kidney. Northern blot analysis showed that hLAT2 mRNA was expressed at high levels in the heart, brain, placenta, kidney, spleen, prostate, testis, ovary, lymph node and the fetal liver. The hTAT1 mRNA was detected at high levels in the heart, placenta, liver, skeletal muscle, kidney, pancreas, spleen, thymus and prostate. Immunohistochemical analysis on the human kidney revealed that the hLAT2 and hTAT1 proteins coexist in the basolateral membrane of the renal proximal tubules. The hLAT2 transports all neutral amino acids and hTAT1 transports aromatic amino acids. The basolateral location of the hLAT2 and hTAT1 proteins in the renal proximal tubule as well as the amino acid transport activity of hLAT2 and hTAT1 suggests that these transporters contribute to the renal reabsorption of neutral and aromatic amino acids in the basolateral domain of epithelial proximal tubule cells, respectively. Therefore, LAT2 and TAT1 play essential roles in the reabsorption of neutral amino acids from the epithelial cells to the blood stream in the kidney. Because LAT2 and TAT1 are essential to the efficient absorption of neutral amino acids from the kidney, their defects might be involved in the pathogenesis of disorders caused by a disruption in amino acid absorption such as blue diaper syndrome.

Purpose: This study was aimed to assess TLE1 as a target molecule of synovial sarcoma. Method: We obtained tissue samples and clinical data from 36 patients who were diagnosed and treated for synovial sarcoma in our hospital. Immunohistochemical staining was performed to detect the expression of TLE1 in synovial sarcoma and normal tissues such as fat, skeletal muscle, peripheral nerve, vascular endothelium, and epithelium. Univariate survival analysis was performed to find whether overexpression of TLE1 is correlated to poor prognosis. Results: TLE1 was expressed in 35 (97%) cases (grade 1 was 5 cases, grade 2 was 28 cases, grade 3 was 2 cases.). Normal tissues from mesenchymal origin did not express TLE1. However, epithelial and endothelial cells showed weak expression (grade 1) of TLE1. The level of TLE1 expression did not have any prognostic significance according to univariate survival analysis. Conclusion: TLE1 may be a new molecular target of synovial sarcoma that differentiates synovial sarcoma from normal mesenchymal cells.

Metabolism of lactate dehydrogenase (EC 1.1.1.27, LDH) was studied to identify the function of LDH-C. Tissues of LDH liver-specific Ldh-C expressed Carassius auratus and eye-specific Ldh-C expressed Lepomis macrochirus after starvation were studied. LDH activity in liver tissue from C. auratus was increased after starvation. And LDH specific activity (units/mg) and LDH/CS were increased in tissues. It means the anaerobic metabolism was taking place in C. auratus after starvation. LDH B₄ isozyme was decreased in skeletal muscle and increased in heart tissue. LDH C₄ isozymes those showed in eye and brain tissues were identified as liver-specific C₄ isozymes and disappeared after starvation. And C hybrid in eye, A₄ isozyme in brain, and both C hybrid and C₄ isozyme in liver tissue were increased, respectively. In L. macrochirus, the level of variation of LDH activities was low but greatly increased especially in eye tissue and LDH A₄ and AC hybrid were increased in brain tissue. The LDH activities in tissues from C. auratus and L. macrochirus remained 30.30-18.64% and 25-18.75%, respectively, as a result of the inhibition by 10 mM of pyruvate. The Km^PYR values of LDH in C. auratus were increased. As a result, LDH liver-specific C₄ isozyme was expressed in liver, brain and eye tissues during starvation. It seems metabolism of lactate was predominant in brain tissue. After starvation, the liver-specific LDH-C was affected more than eye-specific LDH-C.

The purpose of this study was to isolate novel lactic acid bacteria to ferment mulberry leaf extract (MLE) and to investigate its anti-diabetic effect. Lactobacillus plantarum SG-053 isolated from gatkimchi was selected to ferment MLE because it exhibited high α-glucosidase inhibitory activity (96.8%) and enhanced the content of 1-deoxynojirimycin (DNJ), an anti-diabetic substance, in fermented MLE up-to 2.2 times. MLE fermented with L. plantarum SG-053 (FMLE) showed growth promoting activity against L6 myotubes and increased the gene expressions of IRS-1, PI3K p85α, and GLUT-4 up-to 1.4, 2.2, and 1.4 times, respectively, and 2-deoxyglucose uptake up-to 40.7%. In rat skeletal muscle tissue, the expressions of PI3K p85α and GLUT-4 increased by 6.4 and 2.1 times, respectively. These results suggest that L. plantarum SG-053 could enhance the DNJ content of MLE by fermentation and that FMLE is effective in ameliorating insulin resistance via activation of the insulin signaling pathway.

Parkinson's disease is one of the typical neurodegenerative disease and it is caused by the destruction of substantia nigra in brain leading to lack of dopamine secretion, and it presents 4 major motor symptoms such as tremor, bradykinesia, stiffness, postural instability. Furthermore, it causes many non-motor symptoms such as anosmia, REM sleep conduct disorder, orthostatic hypotension, dementia and autonomic ataxia such as lack of adjusting blood pressure, hyperhydrosis, constipation. Dopaminergic therapy is the most commonly used strategy, but long term treatment of levodopa induce various adverse effects. Thus, many people are focusing on new therapies other than established therapies, and there are many tries and approaches with paradigm shift. Our medical team was able to get 4 cases of PD patients who are hospitalized in our hospital, treated by Whole Body Gi-Hyeol Therapy consisting of acupuncture therapy, herbal therapy, and mental therapy, and their conditions improved in perspective of Unified Parkinson's Disease Rating Scale(UPDRS), Heart Rate Variability(HRV), and Quality of life. Among all 4 cases, UPDRS score and quality of life score is gotton better, and among 2 cases SDNN, RMS-SD, TP, LF, HF scores are finely increased. And PDQ-39 score which shows quality of life is also improved. However, in spite of these improvements and positive results, there were no meaningful improvement in a hurt from a fall which is important to the aged, muscular atrophy which causes bone fracture and SMI(Skeletal Muscle Mass Index) which is indicator of osteoporosis. Thus, supplementary treatment about Whole Body Gi-Hyeol Therapy such as more active nutrition intervention, safe and effective kinesitherapy is needed, and from now on continuous case reports and systematic clinical research which has control group must be carried out.

The aim of this study was to examine the metabolic adjustment of lactate dehydrogenase (EC 1.1.1.27, LDH) isozymes to a change in dissolved oxygen (DO) in bluegill (Lepomis macrochirus). After bluegills were adapted to a constant environment in an aquarium, the DO was changed to investigate the activity of LDH isozyme and the relative ratio of subunits A, B, and C for each tissue. When the DO was decreased from 18 ppm to 6 ppm, LDH in skeletal muscle, heart, and brain tissues recovered to the level of control activity within 12, 12, and 6 hr, respectively. LDH activity changed in accordance with a change in DO. The compensation was performed rapidly and is thought to be an important function of LDH in enabling bluegills to adapt to their environment. In bluegill heart, eye, and brain tissues, the relative ratio of subunit A increased and showed a tendency to recover similarly to the subunit ratio of control groups up to 12 hr. It is thought that the anaerobic metabolism using subunit A was increased in the initial stage when DO was changed. In addition, the results revealed that subunit C was more similar to subunit A than subunit B. In bluegills, subunits A and C of LDH seem to be evolutionarily similar. LDH isozymes, mainly containing subunits A and C, are likely responsible for the function of pyruvate reductase, which plays a role in making the bluegill adapt to a hypoxic environment through anaerobic metabolism.

The purpose of this study was to evaluate the relationship between bone mineral density (BMD) and body composition (BC) or backmuscle strength (BS). Sixty-one participants were measured by BMD using ultrasound bone densitometry and Inbody for BC (i.e., SLM=Soft lean mass, SMM=Skeletal muscle mass, FS=Fitness score. et al.), BS after self-questionnaire for life cycle. This study was performed after approving Institutional Review Board and obtaining the informed concent from all participants. Participants was divided into two group by BMD T-score; $T-score{\geq}-1.0$, T-score<-1.0. Statistical analysis was performed by using SPSS ver. 22.0(USA), Spearma test for correlation between BMD and BC or BS. BMD or SLM, BS was increased with increasing physical activity or body mass index. SMM or SMM, FS of BMD $T-score{\geq}-1.0$ group was higher than that of T-score <-1.0 group as well as BS(p>0.05). BMD T-score was correlated positively with SLM(r= 0.424) or SMM(r= 0.431) in men, as well as in women(p<0.05). BS was correlated positively with SLM or SMM, FS. BS was significantly positive correlated with BMD in women group (r= 0.591, p= 0.001), but not in men group. We concluded that BMD is the relationship with SLM or SMM, as well as BS in women.

Objectives: This study is a practice based research conducted to investigate the effectiveness and safety of a 5-day short-term diet program ('Oil-rescue' program) designed to reduce the adverse events and initial dropout rate in obesity treatment. Methods: We retrospectively analyzed 4 Korean medicine clinic patient data who completed 'Oil-rescue' program which is consisting of Gambi-hwan, Bium-hwan, Butgiban-hwan and Jayoon Kyungokgo. The weight change before and after participating 'Oil-rescue' program was primary outcome of our study. Changes in body mass index, body fat mass, skeletal muscle mass, body water content, lean body mass, protein, and minerals were also measured. Results: A total of 35 patients who satisfied the eligible criteria were finally included. The body weight decreased from 69.45±11.86 kg to 67.43±11.58 kg, a total of 2.02±1.03 kg (P<0.001). Body fat mass decreased from 25.77±7.45 kg to 24.98±7.26 kg, a total of 0.78±1.21 kg (P<0.001). Body mass index decreased from 26.39±3.64 kg/㎡ to 25.64±3.49 kg/㎡, a total of 0.75±0.41 kg/㎡. (P<0.001). A total of 15 patients had side effects such as diarrhea, abdominal pain, and insomnia, but all were mild. 16 out of 35 people switched to long-term obesity treatment programs. Conclusions: Through this retrospective practice based research, it was found that the 'Oil-rescue' program effectively reduced body weight, body fat, and body mass index, and the other obesity related parameters. It was a relatively safe and effective short-term obesity treatment program.

Background: We recently showed that gintonin, an active ginseng ingredient, exhibits antibrain neurodegenerative disease effects including multiple target mechanisms such as antioxidative stress and antiinflammation via the lysophosphatidic acid (LPA) receptors. Amyotrophic lateral sclerosis (ALS) is a spinal disease characterized by neurodegenerative changes in motor neurons with subsequent skeletal muscle paralysis and death. However, pathophysiological mechanisms of ALS are still elusive, and therapeutic drugs have not yet been developed. We investigate the putative alleviating effects of gintonin in ALS. Methods: The G93A-SOD1 transgenic mouse ALS model was used. Gintonin (50 or 100 mg/kg/day, p.o.) administration started from week seven. We performed histological analyses, immunoblot assays, and behavioral tests. Results: Gintonin extended mouse survival and relieved motor dysfunctions. Histological analyses of spinal cords revealed that gintonin increased the survival of motor neurons, expression of brain-derived neurotrophic factors, choline acetyltransferase, NeuN, and Nissl bodies compared with the vehicle control. Gintonin attenuated elevated spinal NAD(P) quinone oxidoreductase 1 expression and decreased oxidative stress-related ferritin, ionized calcium-binding adapter molecule 1-immunoreactive microglia, S100β-immunoreactive astrocyte, and Olig2-immunoreactive oligodendrocytes compared with the control vehicle. Interestingly, we found that the spinal LPA1 receptor level was decreased, whereas gintonin treatment restored decreased LPA1 receptor expression levels in the G93A-SOD1 transgenic mouse, thereby attenuating neurological symptoms and histological deficits. Conclusion: Gintonin-mediated symptomatic improvements of ALS might be associated with the attenuations of neuronal loss and oxidative stress via the spinal LPA1 receptor regulations. The present results suggest that the spinal LPA1 receptor is engaged in ALS, and gintonin may be useful for relieving ALS symptoms.
