A great deal of attention has been paid to the quality of life in citizens due to the increased number of long term life expectancy. reported as effective in the health promotion of the senior citizens. In this study, the principal investigator developed an exercise program for the senior citizens, which could be educated and managed by nursing staff. This kind approach may support the need of exercise program on regular base via the social organization, which may mean the intentional change of life style. The exercise program consisted of exercise, health education, and a direct the population of the senior A regularexercise has been nursing care. A quasi -experimental study was conducted to investigate the effects of excercise program on health of the elderly in senior citizen's center. Independent variable was a 9 weeks exercise program. Dependent variables were: 1) physical health [e.g. physical fitness(cardiopulmonary endurance, back muscle strength, grip strength, muscular tolerance, flexibility and body fat proportion), physiologic parameters(blood pressure, pulse, respiration. and blood glucose), and perceived physical health status; 2) mental health measured by depression score; and 3) cognitive perception of exercise measured by usefulness and self-efficacy. A total of 37 subjects was randomly assigned into either the control group (without the exercise program: n=18) or the intervention group(with the exercise program: n=19). The results of the study analyzed using a SAS, were as follows: 1) In physical fitness of physical health, there was a significant improvement in cardiopulmonary tolerance. back muscle strength. muscular tolerance and flexibility in the intervention group, compared to the control group, while no difference in grip strength and body fat proportion. The exercise program resulted in decreases in blood pressure, pulse, respiration and blood glucose within normal range and improvement of perceived physical health status in the intervention group. 2) There was a slight increase of mental health(depression score) in the intervention group compared to the control group. but without statistical significance. 3) There was a significant improvement in cognitive perception of exercise(e.g. usefulness and self -efficacy) in the intervention group, compared to the control group. It was concluded that the exercise program employed in this study was appropriate for women senior citizens and had a positive effect on health in general.

A 37-year old man was admitted due to the left subauricular mass of 6 month duration which was 3 x 4cm sized, pulsatile and slowly growing He was suffered from the intermittent left facial and auricular pain radiating to the occipital area. The carotid angiography revealed 3x4cm sized saccular aneurysm of the left internal carotid artery just above the carotid bifurcation, extending to the mandibular angle level. He was planned to be operated under the direct clamp of internal carotid artery or shunting procedure. But, the back pressure of the internal carotid was 35mmHg, which suggested adequate cerebral collateral. Thereby, aneurysmectomy and restoration of cerebral blood flow with saphenous vein graft was done under the direct clamp of internal carotid artery for 25 minutes. Although mild transient neurologic sequelae such as mydriasis, tongue deviation for 10 days, he recovered completely without any complication. The aneurysmal sac had no thrombus and pathologic finding was compatible with congenital origin.

To regulate cardiac output of the Total Artificial Heart(TAH) physiologically, the hemodynamic information must be toed back to the controller. So far, our group has developed an automatic cardiac output control algorithm using the motor current waveform, It is, however difficult to detect the preload level such as a filling status of ventricular inflow and the variation of atrial pressures within normal physiologic range(0-15 mmHg) by analyzing the motor current which simultaneously reflects the afterload effect. On the other hin4 the interventricular volume pressure(IVP) which is not influenced by arterload but by preload is a good information source for the estimation of preload states. In order to find the relationship between preload and IVP waveform, we set up the artificial heart system on the Donovan type mock circulatory system and measured the IVP waveform, right and left atrial pressures, inflow and outflow waveforms and the signals represented the information of moving actuator's position. We shows the feasibility of estimating the hemodynamic changes of inflow by using IVP waveform. fife found that the negative peak value of IVP waveform is linearly related to atrial pressures. And we also found that we could use the time to reach the negative peak in IVP waveform, the time to open outflow valve, the area enclosed IVP waveform as unfu parameters to estimate blood filling volume of diastole ventricle. The suggested method has advantages of avoiding thrombogenesis, bacterial niche formation and increasing longterm reliability of sensor by avoiding direct contact to blood.

국소한냉자극이 전신 및 국소혈액순환에 미치는 영향과 동계에 있어서 한냉에 대한 적응을 관찰하기 위하여 동계 및 하계에 편균연령 21세의 남녀 대학생 각 60명 및 50명을 대상으로 $5^{\circ}C$의 냉수에 일측 손을 담구어 3분간 국소한냉자극을 가하였다. 침수 1, 2, 3분과 회복기 1, 3, 5분에 침수한 측과 침수 반대측에서 평균혈압, 분시심박수, 광전 모세혈관 맥박의 파고, 피부전기저항을 관찰하여 다음과 같은 결과를 얻었다. 국소한냉자극시 혈압은 증가하였고 하계에서 동계보다 더 큰 증가를 보였다. 회복기에 동계는 서서히 대조치로 회복되나 하계에는 대조치보다 유의하게 감소하였다. 분시심박수는 침수시 증가하며 하계에서 동계보다 더 증가하였고 회복기에는 동계 및 하계 모두 대조치보다 감소하였다. 광전 모세혈관 맥박의 파고는 동계에는 침수 및 침수 반대측 모두 감소하였으나 침수한 측에서 더 크게 감소하였으며 이는 침수한 측에 있어서 한냉의 국소효과에 기인한 것으로 보인다. 하계에는 동계보다 작은 감소를 보였으며 회복기에는 더 빠른 회복을 보여 대조치보다 증가하였다. 피부전기저항은 침수시 침수 반대측에서는 감소하나 침수한 측에서는 유의하게 증가하였다가 회복기에 서서히 감소하였다. 침수 반대측의 감소는 동통에 의한 반응이 한냉에 의한 반응에 첨가되어 나타난 것으로 보이며, 침수한 측은 한냉에 의한 국소효과가 크기 때문인 것으로 보인다. 이상으로 $5^{\circ}C$의 국소한냉자극시 전신적 반응은 한냉자극에 의한 동통성 stress에 기인한 반응이 우세한 것으로 생각되며 김 등$^{39)}$의 보고와는 달리 동계 및 하계의 반응의 차이는 계절에 따른 한냉자극에 대한 주관적 감각의 차이에 의한 것으로 동계에서 한냉기후에 의한 국소한냉자극의 적응현상은 나타나지 않는 것으로 사료된다.

The aim of this study is to determine the phagocytosis-promoting factor(s) for feline peripheral blood polymorphonuclear cells (PMN) by culture supernatant from mono-nuclear cells (MNC) treated with egg white derivatives (EWD). The phagocytic activity of PMN was analyzed by a flow cytometry system. The EWD did not show direct effect on the phagocytic response of PMN. The phagocytic activity of PMN was enhanced by culture supernatant from MNC but not PMN treated with EWD. Therefore, it was suggested that the enhanced phagocytic activity of feline PMN could be mediated by humoral factor(s) released from MNC treated with EWD. Thus, the phagocytosis-promoting factor(s) in supernatant fraction from MNC culture treated with EWD were isolated by reverse phase high pressure liquid chromatography. The resulting supernatant fraction on 29.02 minutes of retention time showed high phagocytic activity of PMN. The molecular weight of this supernatant fraction was 16 to 18 kDa when analyzed by capillary electrophoresis. The isoelectric point was pH 5.76 when assessed by ion-exchange chromatography. These results suggest that EWD stimulates feline MNC to elaborate a phagocytosis-promoting factor, 16 to 18 kDa of molecular weight, which could be an important mediator for the enhancement of phagocytic activity of feline peripheral blood phagocytes. Further study will be needed to elucidate this phagocytic factor.

Background: Smoking effects are relatively well-documented, especially on cancers and cardiovascular diseases. However, the direction and magnitude of association between smoking and obesity remain unclear. Conflicting results so far are thought to stem from the multiple confounding structure of smoking and other obesogenic life style characteristics. Methods: Cotwin control study is a genomic epidemiology design, in which the other twin (=cotwin) serves as a control of the twin. Cotwin control study, discordant for smoking habits can provide powerful evidence of association between smoking and obesity by completely matching genomic information, intrauterine environment, and almost all environmental factors. We selected 3,697 like-sex twin pairs (2,762 male and 935 female pairs) out of 63,666 pairs of adult twins in the existing Korea Twin and Family Register, whose smoking habits are discordant. We used the information of obesity as body mass index (BMI, $kg/m^2$) blood pressure, and blood cholesterol level at the time or later than the smoking information. Paired t-test was done to compare the smoking effects. Results: Lifetime smoking rate was 80.1 % (47.9 current smoker) for men and 10% (1.7% current smoker) for women. Among 2,762 and 935 male and female like-sex twin pairs, 363 male pairs and 20 female pairs correspond to the definition of smoker-nonsmoker pair. The male smokers demonstrated increase in BMI by 0.47, while female smokers show slight decrease (by 0.13), which were not statistically significant. Diastolic and systolic blood pressure, and cholesterol level were slightly increased among smokers by 1.85 mmHg, 0.62 mmHg, and 1.28 mg/dl for men. For women, the results show increase in diastolic blood pressure (3.42mmHg) and cholesterol level (1.25 mg/dl), and systolic pressure (8.17 mmHg). Conclusion: The results refute the possibility that smoking can reduce BMI. Considering the direct adverse effect of smoking, it should be emphasized that smoking do not decrease obesity and thus increase overall metabolic syndrome.
