Objective: To report the improvements with Korean medicine-based integrative cancer therapies on adverse effects of adjuvant chemotherapy in non-small cell lung cancer patients. Method: There were two patients complained cough, rhinorrhea, numbness, general weakness, nausea and dyspepsia after chemotherapy. They got treated centered on Korean medicine including herbal medicine, acupuncture, electro-acupuncture, pharmacopuncture, moxibustion, hand and foot bath. They were also treated Western immunotherapies like Thymosin at regular intervals. The symptoms were measured by the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 for Palliative Care(EORTC QLQ C-15 PAL) and their subjective assessments. Results: Their chief complaints were relieved and their quality of life scores was improved even though they have been receiving chemotherapy continuously. Conclusion: These cases revealed a possibility that Korean medicine-based integrative cancer therapies could improve some symptoms after chemotherapy in non-small cell lung cancer.

내피세포가 제거된 토끼의 적출 장간막 동맥에서 토끼의 대동맥 내피세포로 부터 A23187과 acetylcholine은 NO와 유사한 혈관 이완성 물질 (EDRF)을 유리한다. 이에 첨가하여 A23187은 acetylcholine과는 달리 superoxide anion에 의하여 파괴되지 않는 EDRF도 유리시킴을 확인하고 이의 특성에 대하여 연구하였다. 정상적인 생리영양액에서는 A23187과 acetylcholine의 용량-반응 곡선은 내피세포에 의존하지 않는 sodium nitroprusside의 곡선과 유사하였다. 이들은 methylene blue에 의하여 억제되었다. Hypoxanthine (HX)과 xanthine oxidase (XO)를 bath내로 투여시 phenylephrine에 의한 수축이 일과성으로 증가한 후 지속적으로 이완되었다. HX-XO 반응중에는 A23187은 장간막 동맥을 즉각적으로 이완시켰으나 acetylcholine의 이완작용은 소실되었다. A23187에 의하여 야기되는 장간막동맥의 이완은 50 mM $K^+-PSS$로 수축을 야기시켰을 때에는 나타나지 아니하였다. Superoxide dismutase를 전처치하였을 때는 HX-XO 반응중에도 acetylcholine 뿐만아니라 A23187에 의한 장간막 동맥의 수축은 이완되었다. 한편, acetylcholine에 의하여 야기되는 장간막 동맥의 이완은 A23187에 의하여 야기되는 이완에 비하여 phorbol 12-myristate 13-acetate (PMA)에 훨씬 더 민감하게 억제되었다. 내피세포의 기능과는 무관한 sodium nitroprusside에 의하여 야기되는 이완은 PMA에 의하여 영향을 받지 아니하였다. 이상의 결과로 미루어 볼때, A23187과 acetylcholine은 methylene blue에 의하여 억제되는 내피세포 의존성 이완을 야기시키고, 첨가하여 A23187은 어떤 병적 환경 아래서는 superoxide anion과 PMA에 저항성을 지닌 혈관이완성 물질을 유리하는 것으로 사료된다. 앞으로 A23187에 의하여 유리되는 혈관 이완성 물질이 superoxide anion에 의존하여 생성된 것인지에 대하여는 추후의 연구과제이다.

최근 해상유류오염사고시 사용되는 유화제는 해안으로 이동하여 또 다른 수질오염의 원인으로 문제가 되고 있다. 이 연구에서는 자성을 띠고 있는 흡착제를 이용하여 해수 속에 잔류하는 유화제를 제거하는 기술에 대해서 논의하였다. 본 실험에서는 자성을 띠는 흡착제로서 마그네타이트와 마그헤마이트를 이용하였고, 대표적인 유화제 성분으로는 음이온성 계면활성제인 SDDBS (Sodium dodecylbenzene sulfonic acid)와 비이온성 계면활성제인 Triton X-100 (t-octylphenoxypoly-ethoxyethanol)을 사용하였다. 실험은 두 흡착제의 유화제에 대한 흡착 평형시간과 흡착능에 대한 회분식 실험과 모의 실제 상황에서 흡착제가 영구자석이나 전자석에 의해 수거되는 양상을 알아보기 위한 수조실험으로 나누어 이루어졌다. 마그헤마이트는 계면활성제의 종류와 사용된 물의 종류에 상관없이 제거효율이 일정하게 나타나는데 비해 마그네타이트는 음이온성 계면활성제에 대해 선택적으로 고효율을 보이고 있고, 이온이 존재하는 해수보다는 증류수의 경우가 높은 효율을 보이고 있다. 미그네타이트의 흡착메커니즘은 정전기적 인력에 의한 것으로 판단되고, 마그헤마이트의 경우는 정전기적 인력과 함께 흡착능을 향상시키는 구조적 특정과 표면상태의 특성으로 설명되어진다. 수조실험에서는 흡착이 이루어진 후 자석에 의한 회수는 100%에 가까운 것으로 나타났다. 이와 같은 결과는 두 흡착제와 사석에 의한 유화제 제거방법이 실제 해상에서 적용되었을 때 유화제를 짧은 시간 내에 고효율로 처리할 수 있는 효과적인 방법임을 시사한다.

In order to examine if arsenic, one of environmental stresses, contributes to hypertension as one of cardiovas cular pathological factors, this study was perfarmed in vivo and in vitro, using intacted or pithed rats and aorta ring preparation, respectively. And also the relationship between expression of heat shock protein (HSP) 90 and vasoactives-induced contractile response was elucidated. To measure blood pressure, the carotid arterial pressure was recorded on physiograph(Grass Co. 79E) connected to strain gauge. On the other hand, contractile response of vascular ring preparation isolated from rat was determined in organ bath and was recorded on physiograph connected to isometric transducer. And HSP was detacted by Western blotting whole cell Iysis. Preganglionic nerve stimulation was increased by 26.0% in arterial pressure of rat treated with arsenic. Vascular contractile response was monitored and HSP were measured by Western blotting of whole Iysis prepared from samples exposed with 0, 0.5, 1, 2 and 4 mM of arsenic for 8 hours. The dose-vascular responses of potassium chloride were augmented by increasing dose of arsenic in the strips exposed to arsenic for 8 hours, and were not augmented for 1, 3, 5 hours. And the response of relaxation of rat aorta induced by histamine was not influenced by arsenic stress. The increase of HSP 90 expression in rat aorta was pronounced at 8 hours after 4 mM of arsenic treatment, but HSP 60 expression was not. Arsenic stress not only increased the expression of HSP 90 in the rat aorta, but also augmented contractions to potassium chloride. These results indicated that arsenic stress was sufficient to induce heat shock protein 90, resulting in increased vascular contractility in rat aorta.

Simultaneous Ni and C codeposition by electrolysis was investigated with the aim of obtaining better corrosion resistivity and surface conductivity of a metallic bipolar plate for application in fuel cells and redox flow batteries. The carbon content in the Ni-C composite plate fell in a range of 9.2~26.2 at.% as the amount of carbon in the Ni Watt bath and the roughness of the composite were increased. The Ni-C composite with more than 21.6 at.% C content did not show uniformly dispersed carbon. It also displayed micro-sized defects such as cracks and crevices, which result in pitting or crevice corrosion. The corrosion resistance of the Ni-C composite in sulfuric acid is similar with that of pure Ni. Electrochemical test results such as passivation were not satisfactory; however, the Ni-C composite still displayed less than $10^{-4}$ $A/cm^2$ passivation current density. Passivation by an anodizing technique could yield better corrosion resistance in the Ni-C composite, approaching that of pure Ni plating. Surface resistivity of pure Ni after passivation was increased by about 8% compared to pure Ni. On the other hand, the surface resistivity of the Ni-C composite with 13 at.% C content was increased by only 1%. It can be confirmed that the metal plate electrodeposited Ni-C composite can be applied as a bipolar plate for fuel cells and redox flow batteries.

This study was conducted to evaluate effect of ${\alpha}$-linolenic acid (ALA) and bovine serum albumin (BSA) on viability, acrosome reaction and mitochondrial intact in frozen-thawed boar sperm. The boar semen was collected by gloved-hand method and cryopreserved using freezing extender containing 3 ng/mL ALA and/or $20\;{\mu}g/mL$ BSA. Cryo-preserved boar sperms were thawed in $37^{\circ}C$ water-bath for 45 sec to analysis. Viability, acrosome reaction, and mitochondrial intact were analyzed using flow cytometry. In results, viability of frozen-thawed boar sperm was significantly higher in only ALA+BSA supplement group than control group (p<0.05), whereas there was no difference either in ALA or BSA supplement. However, acrosome reacted sperm in both of live and all sperm population were significantly decreased in all treatment groups than control (p<0.05). Interestingly, mitochondrial intact of boar sperm was enhanced in ALA and ALA+BSA groups compared with control (p<0.05). In this study, we showed that supplementation of ALA and BSA in freezing extender enhanced the sperm viability, mitochondrial intact and decrease acrosomal membrane damage. In conclusion, our findings suggest that quality of frozen-thawed sperm in mammalians could improve by using of ALA and BSA.

The general and some other pharmacological actions of growth hormone without N-terminal methionine(rhGH) were investigated in animals. The hormone had no influences on the central nervous system and on body temperature at a high oral dose of 40 IU/kg in animals. It had neither analgesic nor antiepileptic actions at the high doses. In the isolated ileum and trachea of guinea-pig and isolated stomach fundus and uterus of rat, it showed neither contractive nor relaxing effects at a concentration of $1{\times}10^{-3}\;IU/ml$ in bath, and no inhibitory action at a dose of $1{\times}10^{-3}\;IU/ml$ against the contractions produced by histamine ($5{\times}10^{-5}\;g/ml$), serotonin($1{\times}10^{-5}\;g/ml$), acetylcholine($1{\times}10^{-5}\;g/ml$) and oxytocin($5{\times}10^{-3}\;IU/ml$). Furthermore, the intravenous injection of 20 IU/kg rhGH had no influences on the normal blood pressure and respiration in rabbits. These negative results in pharmacological profile are thought that the hormone may not elicit serious side effects. On the other hand, the rhGH exhibited a weak inhibitory action of glucose tolerance in normal rats, significantly lowered the blood glucose contents in adrenalectomized rats 20 min after i.v. administration of 80 IU/kg, and showed a significant inhibitory effect on in vitro glycerol release in epinephrine-stimulated epididymal fat pad segments of rats.

Concerning the development of suitable healthcare equipment for a aged people at their homes in order to reduce the labor and increase the efficiency in the homehelpers' work, we conducted a study on the actual conditions of healthcare in Kyoto city (healthcare in taking a meal and excretion, moving and taking a bath by using a hand-powered lift, moving by a wheelchair, shower carrier healthcare, assistance in body care and housework) by digital video filming, interviews and layout investigations. On the base of those investigations by using methods for analysis of video pictures, we divided the healthcate work into scenes and e exctracted the main problems in terms of health care equipment, information, environment, healthcare skills, mental burden, social s system, family burden, ete. Furthermore the questionnaire survey of home helpers (18 persons - 50% answers) clarified that more than half of them have lumbago pains and the biggest load in the everyday healthcare c comes from moving the patients or getting them into or out of t the equipment for moving. Finally we considered concrete proposals appropriate for each h healthcare scene image, based on evaluation toward efficiency (design guidelines) for suitable healthcare equipment for aged people at their homes: 1) Design toward a proper posture 2) Design toward self-help possibility 3) Design toward patient active participation 4) Design toward rationality of the whole process 5) Design toward place-appropriate healthcare equipment 6) Design toward healing of mind 7) Good level of healthcare skills 8) Economic, systematic rationality
