  • Homocystinuria is a metabolic disorder caused by a deficiency of cystathionine ${\beta}$-synthase (CBS). Patients with homocystinuria show clinical symptoms such as mental retardation, lens dislocation, vascular disease with life-threatening thromboembolisms and skeletal deformities. Generally, the major treatments for CBS deficiency include pharmacologic doses of pyridoxine or dietary restriction of methionine. However, there is no effective treatment for this disease up till today and gene therapy can be an attractive novel approach to treatment of the disease. We investigated whether a recombinant adeno-associated virus could be used as a CBS gene transfer vector to reduce the excessive homocysteine level in the homocystinuria mouse model. Recombinant adeno-associated virus vector encoding the human CBS gene (rAAV-hCBS), driven by EF1-a promoter, was infused into CBS-deficient mice ($CBS^{-/-}$) via intramuscular (IM) and intraperitoneal (IP) injection. IP injection was more efficient than IM injection for prolongation of lives and reduction of plasma homocysteine levels. After 2 weeks of gene transfer by IP injection, serum homocysteine level was significantly decreased in treated mice compared with the age-matched controls and the life span was extended about 1.5 times. Also, increased expression of CBS gene was observed by immunohistochemical staining in livers of treated $CBS^{-/-}$ mice and microvesicular lipid droplets was decreased in cytoplasm of liver. These results demonstrate the possibility and efficacy of gene therapy by AAV gene transfer in homocystinuria mice.

  • $Elfvingia$ $applanata$, a medicinal mushroom belonging to Basidiomycota, has been used in the effort to cure cancers of the esophagus and stomach, and is also known to have inhibitory effects on hepatitis B virus infection. The hot water soluble fraction (as Fr. HW) was extracted from fruiting bodies of the mushroom. $In$ $vitro$ cytotoxicity tests showed that hot water extract was not cytotoxic against cancer cell lines such as Sarcoma 180, HT-29, HepG2, and TR at concentrations of 10-2,000 ${\mu}g/mL$. Intraperitoneal injection with Fr. HW resulted in a life prolongation effect of 45.2% in mice previously inoculated with Sarcoma 180. Treatment of Fr. HW resulted in a 2.53-fold increase in the numbers of murine spleen cells at a concentration of 50 ${\mu}g/mL$, compared with control. Incubation of murine spleen cells with Fr. HW at a concentration of 500 ${\mu}g/mL$ resulted in improved immune-potwntiating activity of B lymphocytes through an 8.3-folds increase in alkaline phosphatase activity, compared with control. Fr. HW generated 12.5 ${\mu}M$ of nitric oxide (NO) when cultured with RAW 264.7, a mouse macrophage cell line, at the concentration of 50 ${\mu}g/mL$, while lipopolysaccharide, a positive control, produced 15.2 ${\mu}M$ of NO. Therefore, the results suggested that antitumor activities of Fr. HW from $E.$ $applanata$ might, in part, be due to host mediated immunostimulating activity.

  • Objectives: The main goals of cancer treatment are improvement of quality of life and survival prolongation. There is a limitation to prolonging the survival time in hepatobiliary and pancreatic cancer. The purpose of this study was to evaluate the quality of life of hepatobiliary and pancreatic cancer patients who visited for traditional Korean cancer treatment. Methods: We evaluated the quality of life of 23 hepatobiliary and pancreatic cancer patients who visited for oriental medicine treatment at East-West Neo Medical Center from June to October of 2007. FACT-G (Functional Assessment Cancer Therapy-General), used in this study, is a scale for evaluation of QOL confirmed validity and reliability, popularly used in many countries to evaluate QOL of cancer patients. Results: The average age of enrolled patients was 57. There were 10 hepatocellular carcinoma patients, 7 pancreatic cancer patients, 6 biliary tract cancer patients. Twenty one patients were in stage IV and 20 patients had distant metastases. By Sasang constitution, Taeumin were 7, Soyangin were 8, and Soeumuin were 8. The baselines of FACT-G score in the first visit were from 34.33 to 85, and the mean score was 67.3. The mean score of FACT-G in hepatocellular carcinoma patients was 67.5, that of pancreatic cancer patients was 62.5, and that of biliary tract cancer patients was 71. Conclusions: This study is valuable as an initial QOL study of hepatobiliary and pancreatic cancer patients who visited an oriental medical clinic. We believe that consistent studies will be necessary to demonstrate oriental treatment-related quality of life with hepatobiliary and pancreatic cancer.

  • Objective: The present study evaluated the preservation of ram semen at 0℃ using soybean lecithin with a Tris-fructose extender. Methods: Semen was collected by artificial vagina ejaculation from six rams with proven fertility. High quality ejaculates were diluted by soybean lecithin (0.25%, 0.5%, 0.75%, 1.0%, 1.25%) using Tris-fructose extender and control (Tris-fructose egg yolk extender), respectively. The ejaculates were diluted to a concentration of 5×108 sperm/mL, followed by cooling to 0℃ in 90 min and maintaining the temperature for 12 days. The diluted semen samples were examined and recorded for sperm progressive motility, acrosome integrity at 0, 24, 72, 144, 216, 288 h, respectively. Two hundred and twenty-three ewes were inseminated for 216 h with optimal soybean lecithin concentrated semen or control via trans-cervical insemination. Results: The results showed that there were no differences in sperm progressive motility at 0, 24, 72, and 144 h (p>0.05). After 216 h, the sperm progressive motility in the control group and 0.5% concentration groups was significantly higher when compared to 0.25% concentration (p<0.05). The 0.5% concentration group demonstrated the highest survival rate and had no difference with the control group (p>0.05). At 216 h, the sperm progressive motility of all groups was still above 50%. The acrosome integrity of all groups was decreased with prolongation of storage time, but there was no difference at each time point (p>0.05). There was no significant difference in the lambing rate and pregnancy rate between the 0.5% concentration group and the control group (p>0.05). Conclusion: These results suggest that ram sperm is capable of fertilization after preservation at 0℃ with 0.5% of soybean lecithin in Tris-based extender substituted for egg yolk and produce normal offspring after insemination.

  • Death and dying of human being is a comprehensive system, and death orientation, the subjective meaning related to every component of the death system is developed throughout life. This study was designed and carried out to identify, describe and classify the orientations of Korean adult towards the death system. In an attempt to measure the subjective meaning of death and dying, unstructured Q-methodology was used. The 65 Q-statements developed by Kim(1994), used by Kim(1994) and Park(1996) were adopted as Q-population and 39 Q-statements were selected by the three researchers for Q-items for this study. Thirty-three P-samples were sampled from P-population of literate Korean men and women, 35 and 55 years of age, lived in urban Korea for the last 10 years. Sortings of the 39 Q-items according to the level of personal agreement, and a forced normal distribution into the 9 levels were carried out by the P-samples. The Z-scores of the Q-sort data were computed, and the principal components factor analysis by PC-QUANL Program were carried out. The demographic, socio-cultural and health-related attributes of the P-samples were descriptively analysed. Eight types of death orientation were identified ; Type I ; 'naturalist'. Six P-samples. Death is a natural phenomena, to be accepted as it is and to follow its natural course. Prefer to be informed of all facts and possibilities concernig the course of dying and death to occur to self. Type II ; 'life-after-life negator'. Three P-samples. Time and process of death is the destiny of each person. Death means 'darkness' and 'end to every thing, the absolute end'. Yet, wish physical integrity at the dying and after death. Type III ; 'life-after-life believer'. Six P-samples. Men are travellers passing by this life bound to the life-after-life. Priority concerns are on the activities to prepare self for the eternal life ahead. Disregard premature and sudden death. Type IV ; 'here-now believer' Five P-samples. Positive regard to the cremation of the body and donation of the organs on death. Regard religious and customary post-motem rituals meaningless. Negate life-after life. Type V; 'believer of rituals'. Five P-samples. Death being accepted as a part of, a natural end to, and destiny of human life. Concerned to ensure a dignified end to personal life and dignified post-mortem rituals. Type VI ; 'Realist'(derived from Type I). Two P-samples. Life and death as universal reality. The abrupt death at golden age at the peak of happiness is favored to avoid inevitable physical and mental distress of self and the family. Agreed to the cremation of the body. Disregard rituals. Type VII : 'Fatalist' (derived from Type II). Five P-samples. Not favored, yet, all man are destined to death, the inevitable end of all living beings. To ensure dignified end by personal consummation, information on one's dying and imminent death are to be shared. Type VIII ; 'reality avoider'(derived from Type III). One P-sample. Negative to longevity, artificial prolongation of, meaningless and distressful life. Highly positive to postmortem organ donation.

  • 현재 우리나라 요양병원은 노인인구 증가와 함께 지속적으로 증가하고 있다. 요양병원에 입원하는 환자는 주로 만성질환을 가진 노인들로서 장기요양을 목적으로 하기 때문에 요양병원에서 임종하는 경우가 많아 요양병원에서의 임종간호 중요성이 점점 커지고 있다. 이러한 특징에도 불구하고 요양병원 간호사를 대상으로 임종간호에 대한 연구로는 주로 양적연구들로서 임종간호 경험에 대해 심층적으로 파악하기에 제한이 있다. 따라서 본 연구의 목적은 현상학적 방법을 통해 요양병원 간호사의 임종환자 간호경험의 의미가 무엇인지 이해하고 그 현상의 의미를 심층적으로 기술하고 이해하고자 함이다. 본 연구의 대상자는 C 시에 위치한 요양병원에서 6개월 이상 근무하고 있는 간호사 7명을 선정하였다. 연구방법은 심층 인터뷰로 2021년 12월부터 2022년 3월까지 자료를 수집하였다. 인터뷰 자료는 Giorgi의 현상학적 방법으로 분석하였다. 연구 결과 '임종간호에 대한 간호사의 태도', '연명에 대한 양가 감정', '요양병원의 임종간호에 대한 현실', '삶과 죽음에 대한 성찰'으로 나타났다. 따라서 요양병원 간호사의 임종간호 태도를 변화시키고 대처능력을 향상시킬 수 있는 임종간호 보수교육 및 중재 교육프로그램이 개발되어야 할 것으로 사료된다.

  • This study examined effects on shelf-life extension and prevention of starch retrogradation in rye-wheat mixed bread (RWMB) samples prepared with substitutions of 20, 40, 60, and 80% rye sourdough (RSD) as well as a control made with the addition of naturally fermented raisin extract. These effects were investigated using mold growth, water activity, and textural characteristics during a storage period of 8 days at $20^{\circ}C$. The activities of the rye sourdough were examined in terms of pH, total titratable acidity, general bacteria, lactic acid bacteria, and yeast counts. As the incubation time of the sour dough increased, pH decreased, while total titratable acidity increased. General bacteria, lactic acid bacteria, and yeast counts increased with increasing incubation time. Mold grew on the external surface of the control group after 6 days and on the surface of the RSD bread samples after 8 days, respectively. With regard to water activity, the control group had increasing activity as the storage period increased. In addition, the 20, 40, 60, and 80% RSD samples had increasing water activities until the 4th day however, these strongly decreased by the 6th day. In terms of textural characteristics, as the storage period increased, hardness increased, while springiness, cohesiveness, and resilience decreased. There were no significant differences in gumminess among the samples. The control, 20, 40, and 60% RSD samples had decreases in chewiness with increasing storage time, however, the 40% RSD sample did not differ significantly during the storage period. Finally, water activity was negatively correlated with hardness (p<0.05). In conclusion, the results indicate that substituting rye sourdough in rye-wheat mixed bread has a prolongation effect on shelf-life, but no effect on the prevention of starch retrogradation.

  • 'Healthy Japan 21' is a new health policy that has been proposed for the 21st century: it embodies a totally new concept for its viewpoints and methods. To start with, for its goal, the focus is placed on the 'quality of life' or a life that is free of diseases, rather than mere prolongation of life. For its doctrine, the emphasis has shifted dramatically from improving the health of the entire population(the traditional approach for health improvement) to 'achieving an ideal health status for each individual. The ultimate aged society that arrives first in Japan is a society in its ultimate form for human being. Why did Japan become westernized, giving up her traditional culture? Why did she go through industrialization, sacrificing her nature? And why does she try so hard to industrialize the developing countries? These efforts are all preparation for the arrival of a ultimate aged society. During the 20th century, we believed in unlimited possibilities and expanded our social frontier. In the 21st century, on the other hand, a super-aged society(the ultimate society), a glimpse of which we have witnessed from time to time, will descend on us sooner or later. It is expected to arrive first in Japan. 'Healthy Japan 21' is intended to prepare for the arrival of the hitherto unheard of super-aged society by building the physiological basis of people. This policy is social experimentation on an immense social scale, in which questions are posed on the understanding of health, the relationship between individuals and society, the relationship between administration and citizens, the manner by which central and local governments operate, and the new relationship between prevention and therapy, 'Healthy Japan 21' may be summarized as an experiment on a huge scale directed to the ultimate form of human society, in which Japan and each of her citizens play a role and set an example for the rest of the world. Even just by considering various approaches newly suggested for this venture, one may be convinced that it is a policy with features suitable for a country that has already achieved the world's highest longevity.
