The lipase activity of crude enzyme extracted from the molded sardine meal(MSM) 'koji', and lipid classes and fatty acid composition of neutral lipid(NL) and phospholipid (PL) of MSM 'koji' were investigated. The optimum pH and temperature of the crude enzyme was 8.0 and $40^{\circ}C$ using olive oil emulsion as a substrate, but the residual activity depended on pH and temperature. Total lipid contents of the MSM 'koji' consisted of 15.33g/100g NL, 5.45g/100g PL respectively. The major lipid classes of NL were triglyceride ($53.4\%$) and free fatty acid($28.1\%$), that of PL were phosphatidylethanol($32.7\%$), phosphatidylinositol($25.5\%$), phosphatidylcholine($25.1\%$), lyso-phosphatidylcholine($7.3\%$) and sphingomyeline($3.5\%$). The prominent fatty acid fractions of NL were 16:0, 22:6, 18:1 n-9, 18:2n-6 and 20:5, with PL fractions the major fatty acid ratios were 22:6, 16:0, 18:1n-9, 18:2n-6 and 20:5, in the same respective order.

In order to investigate the influence of photosensitized oxidation in the sun-dried irish moss (Chondrus Ocellatus), laver (Porphyra Yezoensis) and ultra violet irradiated oyster (Crassostrea gigas) the oxidation of lipid and isomers of hydroperoxides were analyzed by gas chromatography-mass spectrometry. The lipid contents of oyster, irish moss and layer were $2.7\%,\;0.1\%,\;0.1\%$ of respectively. Peroxide value, 56,7 meq/kg in the raw oyster was increased of 100.9 meq/kg by the U.V, irradiation for 4 hours. Also the peroxide values of the irish moss and laver were increased by the sun-drying. In the identification of hydroperoxides isomers by trimethylsily (TMS) derivative of photo-oxidized lipid from oyster, irish moss and laver, the proportions of positional isomer, 9-OOH and 13-OOH were dominant than those 10-OOH and 12-OOH.

Objectives : The purpose of this study is to investigate the effects of Sophorae radix pharmacopuncture(SRP) therapy on the Chunchu($ST_{25}$) on intestinal disease in rats with dextran sulfate sodium(DSS)-induced colitis. Methods : The experimental model of colitis was induced by an infection of DSS for fifteen days. After colitis was induced, SRP therapy was practiced on the Chunchu($ST_{25}$) once every three days for a total of five times. Afterward, colon length, damage to the colonic mucosa, complete blood count, aspartate aminotransferase(AST), alanine transferase(ALT), blood urea nitrogen(BUN), creatinine, TNF-${\alpha}$ and IL-6 were measured. Results : The results were obtained as below. 1. Colon length was significantly increased in the SRP group 2 compared to the control group. 2. Damage of colonic mucosa was observed less in the SRP groups than in the other groups. 3. The mean rates of white blood cell(WBC), neutrophils and lymphocytes were significantly increased in SRP group 2 compared to the control group. 4. The mean rates of HGB and hematocrit(HCT) were significantly increased in the SRP compared to the control group. 5. No significant differences were shown in AST, ALT, BUN and Creatinine between the SRP groups and the control group. 6. The mean rate of TNF-${\alpha}$ was significantly decreased in the SRP groups compared to the control group. 7. The mean of IL-6 was significantly decreased in the SRP groups compared to the control group. Conclusions : These results indicated that SRP therapy on Chunchu($ST_{25}$) functions as a treatment to the dextran sulfate sodium-induced colitis.

Objectives The purpose of this study is to find out the effect of various concentrations of Hwangnyeonhaedok-tang (HTT) pharmacopuncture on ST25 (天樞) in rats with dextran sulfate sodium (DSS)-induced colitis.Methods Colitis was experimentally induced by feeding rats with water mixed with 5% (w/v) DSS for 20 days. The rats were divided into 5 groups: the normal group (Nor, n=5), the control group - colitis induced rats with no treatment (Con, n=5), the acupuncture group - colitis induced rats with acupuncture applied on ST25 (Acu, n=5), the pharmacopuncture group 1 - colitis induced rats with 0.729 mg/250 g/40 μl of pharmacopuncture applied on ST25 (PA-1, n=5), the pharmacopuncture group 2 - colitis induced rats with 3.645 mg/250 g/40 μl of pharmacopuncture applied on ST25 (PA-2, n=5). The changes in weight, excrement concentration and hemafecia were observed 5 times every 2 days. The colon lengths were measured from appendix to the end of colon after the experiment. Hematological and serological exams were conducted the day after the last treatment by cardiac puncturing anesthetized rats.Results ST25 is the abdominal front point (募穴) of large intestine meridian and is known to have effect in colitis. Various concentrations of HTT pharmacopuncture (HTTP) applied on ST25, in rats with DSS-induced colitis inhibited decrease in colon lengths and body weight in both PA-1 and PA-2 groups. Hematological and serological exam results also showed that HTTP has significant effect on colitis in both PA-1 and PA-2 groups.Conclusions Colon lengths were significantly increased in the acupuncture group, PA-1 group and PA-2 group, compared to the control group. The body weight was significantly increased (p<0.05) in PA-2 group after the first treatment, compared to the control group. TNF-α, IL-6, AST were significantly decreased in PA-1 and PA-2 groups, compared to the control group.

Objective: We evaluated the efficacy of a newly-developed spinal orthoses (V-LSO) by comparing the stabilizing effect, abdominal pressure, and comfort of 3 different semirigid LSOs (classic LSO, V-LSO, and Cybertech^®) during various body movements. Method: Thirty healthy volunteers (23~47 years, 24 males, 6 females) were selected. A dual inclinometer measured the range of motion (ROM) while the participants performed flexion/extension and lateral flexion of the lumbar spine with 3 LSOs. The LSO's pressure on the abdominal surface was measured using 9 pressure sensors while lying, sitting, standing, flexion/extension, lateral flexion, axial rotation, and lifting a box. Comfort and subjective immobilization were analyzed by a questionnaire. Results: V-LSO had a statistically significant effect on flexion over Cybertech^®. No significant differences were noted during extension and lateral flexion between the 3 LSOs. The abdominal pressure showed no significant differences while supine. While sitting, standing, and lifting a box, the mean abdominal pressure for V-LSO were significantly higher than those for Cybertech^®. During lumbar flexion, the mean abdominal pressures for classic LSO and V-LSO were significantly higher than that of Cybertech^®. For extension, lateral flexion and axial rotation, the abdominal pressure for V-LSO was significantly higher than those of classic LSO and Cybertech^®. In the subjective analysis, V-LSO and Cybertech^® scored best for comfort. Conclusion: The V-LSO and Cybertech^® were more comfortable than the classic LSO, and hence, may have improved compliance with decreased discomfort. V-LSO may be superior to the other LSOs in restricting lumbar movement and increasing intraabdominal pressure.

In this study, the O/W emulsification processes with the natural surfactants that were extracted from Medicago sativa L. and Sapindus saponaria L. as emulsifiers were optimized using the central composite design-response surface methodology (CCD-RSM). Herein, independent parameters were the amounts of mixed emulsifiers, the mixing ratio of natural emulsifiers (soapberry saponin/alfalfa saponin), and the emulsification time, whereas the reaction parameters were the emulsion stability index (ESI), mean droplet size (MDS), and antioxidant activity (DPPH radical scanvenging activity). Through basic experiments, the ranges of operation variables for the amount of mixed emulsifiers, the mixing ratio of natural emulsifiers, and the emulsification time were 12~14 wt%, 30~70%, and 20~30 min, respectively. The optimum operation variables deduced from CCD-RSM for the amount of mixed emulsifiers, the mixing ratio of natural emulsifiers, and the emulsification time were 13.2 wt%, 44.2%, and 25.8 min, respectively. Under these optimal conditions, the expected values of the ESI, MDS, and antioxidant activity were 88.7%, 815.5 nm, and 38.7%, respectively. And, the measured values of the ESI, MDS, and antioxidant activity were 90.6%, 830.2 nm, and 39.6%, respectively, and the average experimental error for validating the accuracy was about 2.1%. Therefore, it was possible to design an optimization process for evaluating the O/W emulsion process using CCD-RSM.

Purpose: To assess the chronological changes of disease-related kyphosis after chemotherapy alone. Materials and Methods: A total of 101 children aged 2 to 15 years with spinal tuberculosis, accompanied by various stages of disease processes were enrolled for analysis. By utilizing the images in them, the growth plate condition and chronological changes of kyphosis after chemotherapy were analyzed at two points in time; the first assessment was at post-chemotherapy one-year and second at the final discharge. Results: Complete disc destruction in the cervical, dorsal and lumbosacral spines was observed in 2 out of 40 children (5.0%), 8 out of 30 children (26.7%), and 6 out of 31 children (19.4%), respectively. In those cases, the residual kyphosis inevitably developed. In the remaining children, the discs were intact or partially damaged. Among the 101 children kyphotic deformity was maintained without change in 20 children (19.8%). Kyphosis decreased in 14 children (13.9%), while it increased in 67 children (66.3%) with non-recoverably damaged growth plate. Conclusion: Although it is tentatively possible to predict the deformity progress or non-progress and spontaneous correction at the time of the initial treatment, its predictive accuracy is low. Therefore, assessment of the chronological changes should be performed at the end of chemotherapy. In children with progressive curve change, assessment of deformity should be continued until maturity.

Objectives : It was conducted to experimentally analyze the effects of acupuncture treatment at CV12, ST25, and ST36 on weight, FBCS, fat metabolism, microbiome, and metabolome changes in the general diet rat and the high-fat diet rat. Methods : It was classified into four groups: general diet & non-treatment group (ND), general diet & acupuncture treatment group (ND+AT), high-fat diet & non-treatment group (HFD), and high-fat diet & acupuncture treatment group (HFD-AT). After acupuncture treatment was performed on CV12, ST25, and ST36, changes in body weight, FBCS, fat metabolism, microbiome, and metabolome were analyzed. Results : Compared to the ND group, acupuncture treatment performed on CV12, ST25, and ST36 in the ND+AT group had no significant effect. Compared to the HFD group, CV12, ST25, and ST36 acupuncture in the HFD+AT group reduced weight, fat weight, inflammatory cytokine IL-6 expression, and lipid droplet accumulation in liver tissue. Acupuncture can promote fat metabolism and relieve inflammatory conditions. Differences in diversity between ND and HFD groups were clear in changes in microbiome, fecal metabolites, and serum metabolites. As a result of some microbiome and metabolites involved in fat decomposition, intestinal lipid absorption, and blood lipid concentration control, such as Intestinimonas, Ruminococcus 1, pyroglutamic acid, tryptophan, and inositol, it was observed that the acupuncture treatment effect was evident in the disease-induced imbalance. Conclusions : Acupuncture treatment performed on CV12, ST25, ST36 clearly observed various regulatory actions on obesity induced by high-fat diet, confirming that the action of acupuncture treatment mainly plays a role in controlling an unbalanced state.

This study reports on diffuse leptomeningeal glioneuronal tumor (DL-GNT) in a 29- year-old male. DL-GNT is a rare central nervous system (CNS) tumor mostly seen in children and only few cases have been reported in adult patients. Our patient presented with a chronic headache that lasted for five months. MR imaging showed mild hydrocephalus, multiple rim-enhancing nodular lesions in the suprasellar cistern, diffuse leptomeningeal enhancement in the lumbosacral area, and multiple small non-enhancing cyst-appearing lesions not suppressed on fluid attenuated inversion recovery (FLAIR) images in the bilateral basal ganglia, thalami, and cerebral hemispheres. Under the impression of germ cell tumor with leptomeningeal seeding, the patient underwent trans-sphenoidal tumor removal. DL-GNT was pathologically confirmed and FGFR1 mutation was detected through a next-generation sequencing test. In conclusion, a combination of leptomeningeal enhancement and multiple parenchymal non-enhancing cyst-appearing lesions not suppressed on FLAIR images may be helpful for differential diagnosis despite overlapping imaging features with many other CNS diseases that have leptomeningeal enhancement.
