The objective of this study was to evaluate the anti-melanogenic effects of Hizikia fusiforme (HF) fractions in ${\alpha}$-melanocyte stimulating hormone-induced B16F10 mouse melanoma cells. Ethanol extractions of Hizikia fusiforme (EEHF) were subjected to fraction by using dichloromethane (CFHF), ethyl acetate (EAFHF), butanol (BFHF), and water (WFHF). EEHF, CFHF, and EAFHF inhibited tyrosinase activity and melanin synthesis in B16F10 mouse melanoma cells in a dose-dependent manner. The melanin contents were inhibited by 40.5% and 33.2% in response to treatment with 50 ${\mu}g/ml$ of EEHF and CFHF, respectively. In addition, tyrosinase activities showed a 53.3% and 54.1% reduction in treatment with 50 ${\mu}g/ml$ of EEHF and CFHF. Western blotting analysis showed that EEHF, CFHF, and EAFHF inhibited tyrosinase, TRP-1, TRP-2, and MITF expression in a dose-dependent manner. In conclusion, these findings indicate that ethanol and dichloromethane fractions of Hizikia fusiforme, which inhibit melanin synthesis and tyrosinase activity, are effective skin-whitening agents.

An 80% ethanol extract of Hizikia fusiforme was obtained and followed by successive fractionation using the organic solvents n-hexane, ethyl acetate, and n-butanol to identify the antioxidative substance. The aqueous part of the nbutanol fractionation step, showing high antioxidative activity, was subjected to reverse-phase liquid chromatography. As a result, a substance purified from a BB-2 fraction showed high antioxidative activity. The m/z 419 [M+H] molecular ion peak in the fraction was observed by the analysis of the ESI-LC/MS spectrum. By the analysis of 1H NMR (500 MHz, DMSO-$d_6$) and $^{13}C$ NMR (125 MHz, DMSO-$d_6$) spectra, a unique compound of the fraction was biochemically identified as a 5-hydroxy-3,6,7,8,3',4'-hexamethoxyflavone (5HHMF). We also investigated the effect of 5HHMF on human gastric AGS carcinoma cells. Western blot analysis suggested that the flavone substantially increased the levels of the death receptor-associated apoptosis mediators Fas, Fas L, FADD, TRADD, and DR4 in a concentration-dependent manner. The levels of Fas, Fas L, TRADD, and DR4 in the cells treated with 5HHMF ($5{\mu}g/ml$) were approximately 26.4-, 12.8-, 6.7-, and 9.8-times higher than those of non-treated cells, respectively. Of note, the level of FADD protein in the cells exposed to 5HHMF ($1{\mu}g/ml$) increased approximately 9.6-times. In addition, the cleavage of caspase-3, -8, and -9 in cultured AGS cells treated with 5HHMF was significantly confirmed. Therefore, our results suggest that 5HHMF from H. fusiforme is involved in the induction of death receptor-associated apoptosis mediators in human gastric AGS carcinoma cells.

Purpose: The aim of this study was to investigate the effects of physical therapy combined with a virtual reality (VR) game on pain, quality of life (QOL), engagement, and knee function in post-knee-surgery patients. Methods: Twenty-four patients who had undergone knee surgery four weeks or more before the study were recruited. Two withdrew from the study during the four-week experimental period, and a total of 22 patients were included in the final analysis. Routine physical therapy consisting of electrostimulation (10 min.) and therapeutic massage (10 min.) was the base intervention for all groups. The experimental group (n = 10) was additionally exposed to a VR game intervention, while the control group (n = 12) underwent an intervention involving similar motions as the experimental intervention but with no VR. The intervention for the experimental group used the game Rig Fit Adventure on Nintendo switch. Both groups underwent their respective interventions 3 times a week (35 min. per session) for 4 weeks. Pain was assessed using the numeric rating scale (NRS), and QOL was assessed using the EuroQol five-dimensional five-level questionnaire (EQ-5D-5L). Engagement was assessed using the Korea flow state scale (K-FSS). Finally, knee movement and function were assessed based on knee flexion and extension, range of motion (ROM), and Western Ontario and McMaster Universities Arthritis Index (WOMAC). Results: After the four-week physical therapy, both groups showed significant reductions in pain (on the NRS), increased knee ROM (flexion), better WOMAC scores, and increased EQ-5D-5L scores (p < 0.05), with the experimental group showing significantly better improvements in EQ-5D-5L and K-FSS scores (p < 0.05). Conclusion: The results of this study confirm that a VR-game-integrated intervention is effective for improving pain, QOL, engagement, and knee function in post-knee surgery patients and that VR-game-integrated interventions could be therapeutic alternatives for patients bedridden for prolonged periods with little motivation for rehabilitation.

This study has been carried out to secretion antibodies for the purpose of preventing the infection of Helicobacter pylori and using them as a supplement for treatment. This experiments have been separated antigens from H. pylori and observed into antibody production and the agglutination of H. pylori for the separated antigens. As major antigenic proteins separated from H. pylori, the following could be verified: 12 kinds of band for whole cell (WC), seven kinds of band for outer membrane protein (OMP), three kinds of band for crude urease, and one kind of band for lipopolysaccharide (LPS). The IgG anti-H. pylori antibody of separated antigens showed $77.9{\pm}6.4{\mu}g/ml$ for we (L), $84.9{\pm}6.4{\mu}g/ml$ for OMP, and $123.8{\pm}2.9{\mu}g/ml$ for crude urease, at the same antigen concentration of $20{\mu}g/100ull$, which showed the most at the crude urease. And it turned out that the IgA antibodies were generated with $2.5{\pm}0.32{\mu}g/ml$ for WC (L), $2.0{\pm}0.43{\mu}g/ml$ for OMP, and $1.3{\pm}0.25{\mu}g/ml$ for crude urease, which demonstrated the most for WC (L) antigens. As a result of verifying the immunogenecity of antigenic protein through the Western blotting, major antigenic substances could be confirmed as follows: 10 kinds for WC, six kinds for OMP and three kinds for crude urease. The agglutination values on the H. pylori of the antibody were $2^5,\;2^5,\;2^6\;and\;2^7$ at the antigen serums of anti-WC (H), anti-WC (L), anti-OMP and anti-crude urease, respectively, which indicated the highest for the antigen serum of anti-crude urease. The urease activation-inhibiting absorbance of antigen serum created by each antigen was $0.14{\pm}0.01$ for WC (H), $0.16{\pm}0.01$ for WC (L), $0.18{\pm}0.03$ for OMP, and $0.18{\pm}0.04$ for urease, demonstrating a significant inhibiting effect, compared with $0.26{\pm}0.02$ of the control group.

In spite of recent remarkable recent development in both western and oriental medical sciences, there is still only a shallow understanding of individual differences for various prognoses of incurable diseases and immunopathy diseases. Nevertheless, the care, cure and prevention methods of Sasang Constitutional Medicine are broadly used as an effective treatment of incurable diseases like immunopathy diseases and stress-related diseases and diseases due to aging. In this sense, the establishment of classification norms is urgent and essential for the worldwide application of Sasang Constitutional Medicine(SCM). This study began with the confirmation process of whether Sasang Constitutional types exist in Americans. To accomodate for cultural differences, the distinguishing tool was readjusted so that Sasang Constitutional Types in Americans could be determined. Hence, the selected tool is the new QSCCII+, which is a newly revised English version of the QSCCII. QSCCII was made and standardized by Dept. of SCM in Kyung Hee Medical Center and Dr. Kim7). The evaluation methods of the old version were improved in the new QSCCII+ through necessary statistical manipulation. The original QSCCII was officially authorized by the Korean Society of Sasang Constitutional Medicine as the only computerized version of Sasang diagnostics. This study is the first attempt to design a new diagnostic tool for the classification of Sasang Constitutional types in North Americans with the revision of QSCCII. The subjects of this study were selected from the cooperative people among the students and staffs of the University of Bridgeport and the patients who visited the Clinic in the Health Science Center. This study takes for about 1 year from 1998. 8 to 1999. 8 The conclusions of the study can be summarized as follows: 1. Sasang constitutional types also exist in Americans. It can also naturally be inferred that Sasang Constitutional types exist in all human beings, for there are many different human races in America. 2. There are more So-Yang In's than any other types in American white people. This result confirms the hypothesis that there also exist Sasang Constitutional types in westerners. 3. The result of repetitive tests suggests that the new QSCCII+ is an effective diagnostic tool for westerners when we consider the constant diagnostic results of the QSCCII+. 4. Sasang Constitutional types exit in the sample group regardless of racial difference. 5. The question items that were not often checked by Americans need to be modified into more understandable expressions. 6. The standardization of diagnosis for Americans should be established by use of the QSCCII+ 7. It can be guessed that there are many Tae-yang In's among the 71 persons who could not be clearly classified by the QSCCII+. Due to the scarcity of Tae-yang-In in general, it is important to improve upon the discernability of the QSCC II+. 8. The results of the Sasang Constitutional distribution in North Americans are as follows: The percentage of So-yang In distribution in the sample group is 36.25%(87persons), that of Tae-eum In is 13.75%(33persons), and that of So-eum In is 20.41%(49persons).

Objective : The purpose of this study was to investigate the anti-caner effect of cobrotoxin on the prostatic cancer cell line (PC-3).The goal of study is to ascertain whether cobrotoxin inhibits tile cell growth and cell cycle of PC-3, or the expression of relative genes and whether the regression of PC-3 cell growth is due to cell death or the expression of gene related to apoptosis. Methods : After the treatment of Pc-3 cells with cobrotoxin, we performed 형광현미경, MTT assay, Western blotting, Flow cytometry, PAGE electrophoresis and Surface plasmon resonance analysis to identify the cell viability, cell death, apoptosis, the changes of cell cycle and the related protein, Adk, MAP kinase. Results : 1. Compared with normal cell, the inhibition of cell growth reduced in proportion with the dose of cobrotoxin(0-16nM) in PC-3. 2. Cell viabilities of 0.1, 1, 4nM cobrotoxin treatment were decreased and those of 8, 16nM were decreased significantly. 3. S phase of cell cycle was decreased at the group of 1, 2, 4, 8, 16nM cobrotoxin, but M phase was increased at 0.1, 1, 2, 4, 8, 16nM cobrotoxin. 4. Cox-2 expression after cobrotoxin was peaked at 12hours and was decreased significantly after 6, 12, 24 hours. 5. The expression of Cdk4 was decreased dose-dependently at 1, 2, 4, 8nM cobrotoxin and was decreased siginificantly at 4, 8nM Cyclin D1 was decreased at 1, 2, 4, 8nM and Cycline E was not changed. Cycline B was decreased at 1, 2, 4, 8nM dose-dependently and was decreased siginificanlty at 2, 4, 8nM. 6. The expression of Akt was decreased at 1, 2, 4, 8nM dose-dependently and was decreased significantly at 2, 4, 8nM. 7. ERK was increased at 1, 2nM and decreased at 4, 8nM, p-ERK was increased at 1, 2, 4 nM, but decreased at 8nM. JNK and p-JNK were increased at 1, 4, 8 nM. p38 was increased at 2nM p-p38 was increased at lnM but decreased significantly at 2, 4, 8nM. 8. The nucli of normal cells were stained round and homogenous in DAPI staining, but those of PC-3 were stained condense and splitted. Apoptosis was increased dose-dependently at 2, 4, 8, 16nM and increased significantly at 2, 4, 8, 16nM. 9. Bax wasn`t changed at 1, 2, 4, 8nM and Bcl-2 was decreased significantly at 1, 2, 4, 8nM. Caspase 3 and 9 weren`t changed at 1, 2, 4nM but were decreased significantly at 8nM. Conclusions : These results indicate that cobrotoxin inhibits the growth of prostate Cancer cells, has anti-cancer effects by inducing apoptosis.

Purpose: The purpose of this study is to evaluate the effect of rehabilitation education on the reduction of the stress of family members who have patients suffering from stroke and to find a new way to nurse the patients and their family. Subjects & Methods: The subjects were sixty-one family members with the patients who had been hospotalized in K hospital of oriental medicine from september the 9th, 1996 to september the fourteen, 1996. This study was performed by simulated control group pretest-posttest design; pretest was done on the control group through a questionnaire, counselling and observation while posttest was done on the experimental group 1-2 days after systemic rehabilitation education. To teach the patients and their family, the amended version of a book written by Lee Hae-jin was used as a tool for systemic rehabilitation education. As a method to estimate ADL score, modified Kang's method was applied and ADL score was measured by well-trained technician. As for the tool to estimate the degree of family stress, Choi's method adjusted to this study was applied. In the analysis of the data, social property of the patient and the characteristic of the disease were surveyed in $X^2$ examination to confirm the consistency between the experimental group and the control group. The diffrence in the degree of the stress, which is a dependent factor, was examined by t-test. The difference in ADL score between the experimental group and the control group was examined by t-test. The difference in the degree of the stress according to the general feature of the family with stroke patient, social property of the patients and the characteristic of the disease were surveyed by F examination. The difference in family stress according to the degree of ADL was surveyed by F examination. RESULTS: 1. After hypothetically-examined systemic rehabilitation education, the total of the score of family stress surveyed in 34 items of three domains was compared between the experimental group and the control group. There was no statistically significant difference between two groups; mean score of experimental group=2.28, that of control group=2.93(t=.17, df=59, p=. 66). 2. In the survey on family stress in 34 items, the items over mean score 3.0 were firstly the anxiety of possible disability and relapse of the disease and secondly to watch the patient's suffering without doing anything in the domain of the change of the disease and the difficulty in caring. And the items of the lowest stress with less than mean 2.0 score were little chance to meet the relative and friends, inconsistent treatment and attitude of the medical workers and the change of the attitude of the relative due to the patient orderly in the domain of social and personal relation and the responsibility as the family. The items which showed the difference between two groups were aggravation of neighboring patient(t=3.36, df= 59, p=.001) and the possibility of patient's death(t=2.19, df=58.38, p=.033) in the domain of the change of the disease and the difficulty in caring. 3. In the study on the stress difference according to general features of the family with the stroke patient, the score of family stress with the occupation was higher with mean 2.49 than that of the family stress without occupation with mean 2.16, but there was no significant difference. (F=5.21, df=1/59, p=.026). 4. In the study on the stress difference according to social property of the patient and the characteristic of the disease, there was significant difference in the age of the patients (F=2.98, df=3/57, p=.039). These results show that even if there is no statistically significant difference between two groups, sixteen of the experimental group are less than 3.0 in ADL score(standard 6 score)while eight of the control group are less than 3.0 and that ten of the experimental group are in the year range of 39-49 while four of the control group are in the year range of 39-49 which showed significant difference in family stress. These imply that there is a possibility that the experimental group have serious and fundamental stress resulting in high pretest stress compared with the control group. It might be due to the characteristic of simulated control group pretest-posttest design that the psychologic-supportive effect by the education was not observed. On the basis of these results, the followings are suggested. 1) A study on the nursing-mediated method to reduce the stress in the items which are not resolved by rehabilitation education, a study on nursing according to the patient's age and a study on the supportive nursing toward the family with occupation are required. 2) More than two times consecutive nursing-mediated rehabilitation education to measure the family stress is required. 3) Comprehensive and multilateral systemic education program including the instruction on western-eastern medicine, physical therapy, exercise and diet through collaboration of the experts in each field is required. 4) Family stress at home as well as in the hospital needs to be estimated and home rehabilitation and home-nursing needs to be continued.

This study investigated the anti-inflammatory effects of Ligustrum ovalifolium H. (LOH) leaf extracts on RAW264.7 macrophages. Cell toxicity was determined by MTT assay. We evaluated the anti-inflammatory effects of LOH extracts by measuring nitric oxide (NO), reactive oxygen species (ROS), inducible NOS (iNOS) production, and cyclooxygenase-2 (COX-2) expression by Western blotting. LOH ethanolic extracts (0.05, 0.1, and 0.2 mg/mL) significantly suppressed LPS-stimulated production of NO. The intracellular ROS level also significantly decreased. LOH ethanolic extracts reduced the expression of iNOS and COX-2 proteins. The present results show that LOH ethanol extract has potent anti-inflammatory effects on RAW264.7 macrophages. These results also suggest that the anti-inflammatory effects of LOH extracts may be related to the inhibition of LPS-stimulated ROS and NO production. Therefore, ethanolic extracts of LOH leaves may be utilized as a good source of functional foods for protection against inflammatory diseases.
