The purpose of this study was to investigate the possibility of medicinal plants application as an edible functional food resource. We carried out to develop a traditional functional beverage by using hot-water extraction of 4 medicinal plants (Polygonatun sibiricum, Ophiopogonis radix, Lycii fructus, Schizandriae frutcus) and we examined the effects of drink on physiological response during exercise and recovery phase. The subjects were male baseball players, and exercise protocol was performed with 45 minutes treadmill running and 85％ VO$_2$ max intensity. Brix, pH and titratable acidity of developed drink were 9.5％, 3.3 and 0.22％. The approximate nutritional composition of beverage was carbohydrate, 5.98％, total dietary fiber, 0.42％, crude protein, 0.70％, crude fat, 0.20％ and crude ash, 0.20％. Developed. traditional functional beverage contained K (4.00 mg％), Na (3.68mg％), Ca (2.54mg％), Mg (1.60mg％) and Fe (0.29mg％). Developed beverage drinking group showed a lowest heart rate during exercise and recovery phase than the other two group (water group and ion beverage group). In the change of blood lactate concentration, developed beverage intake group showed a significant lowest values during exercise and recovery phase. And blood hematocrit values and osmolarity were lowest in the developed beverage intake group. In these results, exercise performance capacity was expected to improve most highly with the developed drink from composition with medicinal plants. Also developed beverage was effective in recovery of exercise-induced fatigue. Thus developed drink with medicinal plants can be used as a functional material improving decrease fatigue effects in beverage industry.

To compare the sedative effects using intermittent intravenous bolus injection with tiletamine-zolazepam (n = 5, TZ group), xylazine-ketamine (n = 5, XK group) and propofol (n = 5, PI group), we investigated the changes of hemodynamic (heart rate, arterial pressure), $SpO_2$, rectal temperature, respiratory rate and pain score during 60 minute sedation and 40 minute recovery period in beagle dogs. The value of rectal temperature was significantly higher in PI groups (p<0.05) during recovery period. The value of heart rate was significantly lower in XK group (p<0.05) during sedation. The changes of respiratory rate were similar tendency in all groups. The change of $SpO_2$ was stable during sedation and value was significantly higher in PI group (p<0.05) during recovery period. The value of systolic arterial pressure (SAP) was significantly lower in XK group (p<0.05) than PI group during sedation and recovery period. Low analgesic effect occurred in PI group. We concluded that intravenous anesthesia by intermittent bolus injection with propofol is useful in stabilizing rectal temperature, $SpO_2$ and hemodynamic during sedation and provide fast recovery, but have low analgesic effect.

In this paper, we quantitatively evaluated the anxiety data from humans in an anxiety state. It has been reported that the electric signals of human can be correlated with their emotional state. We chose heart rate, respiration rate, temperature and skin conductance as the anxiety parameters. For experiment protocol, the subject was given exercising load to induce the anxiety state and the exercise was done using the FITRON Cycle Ergometer. We divided the data into three stages: rest period, exercise period, and recovery period. During evaluation, We counted the heart rate, slope of heart rate, temperature change, and the skin conductance.

Background: The oxygen uptake efficiency slope (OUES) is the most important index for accurately measuring cardiopulmonary function in patients with acute ischemic heart disease. However, the relationship between the OUES variables and important cardiopulmonary function parameters remain unelucidated for patients with acute ischemic heart disease, which accounts for the largest proportion of heart disease. Objects: The present cross sectional clinical study aimed to determine the multiple relationships among the cardiopulmonary function variables mentioned above in adults with acute ischemic heart disease. Methods: A convenience sample of 110 adult inpatients with ischemic heart disease (age: 57.4 ± 11.3 y; 95 males, 15 females) was enrolled at the hospital cardiac rehabilitation center. The correlation between the important cardiopulmonary function indicators including peak oxygen uptake (VO₂ peak), minute ventilation (VE)/carbon dioxide production (VCO₂) slope, heart rate recovery (HRR), and ejection fraction (EF) and OUES was confirmed. Results: This study showed that OUES was highly correlated with VO₂ peak, VE/VCO₂ slope, and HRR parameters. Conclusion: The OUES can be used as an accurate indicator for cardiopulmonary function. There are other factors that influence aerobic capacity besides EF, so there is no correlation with EF. Effective cardiopulmonary rehabilitation programs can be designed based on OUES during submaximal exercise in patients with acute ischemic heart disease.

The increasing use of cardioplegic solution for the reduction of ischemic tissue injury requires that all cardiplegic solution be carefully assessed for any protective or damaging properties. This study describes functional, enzymatic and structural assessment of the efficiency of three cardioplegic solutions (Young & GIK, Bretschneider, and $K^{+}$ Albumin solution) in a Modified Isolated Rat Heart Model of cardiopulmonary bypass and ischemic arrest. Isolated rat heart were subjected to a 2-minute period of coronary infusion with a cold cardioplegic or a noncardioplegic solution immediately before and also at the midpoint of a 60-minute period of hypothermic ($10{\pm}1$. C) ischemic cardiac arrest. The results of this study were as follow: 1. Spontaneous heart beat after ischemic arrest occured 16 seconds later after Langendorff reperfusion in the Young & GIK group (n=6), and 40 second later in the Bretschneider group (n=6) and 6 minute later in the $K^{+}$ Albumin group (n=6), and 16 minute later in the control group (non-cardioplegia). A good recovery state of spontaneous heart beat was shown in the Young & GIK and Bretschneider groups. 2. The percentage of recorveries of heart function at 30 minute after postischemic working heart perfusion were : heart rate $91.6{\pm}3.1$% (P<0.01)m oeaj airtuc oressyre $83{\pm}3$% (P<0.01), coronary flow $70{\pm}8$% (P<0.05) and aortic flow flow rate $39{\pm}9.3$% (P<0.05) in the Young & GIK group. This percentage of recoveries of the Young & GIK group was significantly greater than the control group. In the Bretschneider group, the percentage of recoveries were : heart rate $87.8{\pm}7.5$%(P<0.05), peak aortic pressure $71{\pm}2.3$% (P<0.05) and aortic flow rate $33.2{\pm}6.6$%(P<0.05). hte percentage of recoveries were significantly greater than in the control group. In the $K^{+}$ Albumin group, recoveries of heart function were poor. 3. Total CPK leakage was $131.2{\pm}12.75$IU/30 min/gm. dry weight in the control group, $50.65{\pm}12.75$IU in the Young & GIK gruop, $69.40{\pm}32.21$Iu in Bretschneider group, and $103.65{\pm}15.47$IU in the $K^{+}$ Albumin group during the 30 minute postischemic Langendorff reperfusion. Total CPK leakage was significantly less (P<0.001) in the Young & GIK group, than in the control group. 4. Direct correlatin between percentage recovery of aortic flow rate and total amount of CPK leakage from Myocardium was noticed.(Correlation Coefficient r = 0.76, P<0.001). 5. Mild perivascular edema was the only finding of light microscopic study of myocardium after 60 minute ischemic arrest with cold cardioplegic solutions and hypothermla.

배경: 빈맥을 이용하여 심부전을 만드는 방법은 확장성 심근증 모델 중에서 가장 좋은 방법으로 심장에 외과적 손상 혹은 약물의 독성을 최소화할 수 있고 사람의 심부전에 가장 가까우며 조작하기 쉬운 장점이 있다. 새로운 술식의 효과를 검증하기 위하여 심부전이 진행중인 모델에서 동물실험을 시행하는 것은 결과를 얻기 전에 실패할 가능성이 높다. 심부전의 진행을 중지시킨 회복궤도의 변화를 비교하는 방법은 심부전 악화에 의한 사망률을 줄일 수 있는 새로운 방법이지만 빈맥 조작 기술에 따라 저자마다 상당한 차이가 있어 이에대한 자료의 정립이 필요한 실정이다. 대상 및 방법: 21마리의 개(체중 25-35kg)를 대상으로 1)정상의 심장, 2) 심부전 심장, 3) 회복기 4주 4) 회복기 8주 등 4가지로 나누었다. 전신마취하에 우심실첨부에 박동기 전극을 삽입하여 빈맥은 처음 170회/분부터 매주 20회씩 프로그래머를 이용하여 증가시켰다. 4주 후 심부전이 발생하면 8주간의 회복기 동안 회복 궤도를 추적하였다. 심장의 크기와 혈역학적 변화를 관찰하고자 초음파는 2주마다, Swan-Ganz 도자와 열희석법은 4주마다 검사를 실시하여 이완기 말기 좌심실 체적, 수축기말기 좌심실 체적, 심박출율, 중심정맥압, 폐동맥압, 폐동맥 쐐기압, 우심실압, 일회박출량 등을 측정하였으며, 정상과 심부전 심장 상태에서 혈중 카테콜라민을 측정하였다. 그 외 심전도 및 대퇴동맥 도자를 넣어 맥박수, 혈압을 측정하였다. 정상심장, 심부전 심장, 회복기 4주 및 8주에서 측정한 값은 평균$\pm$표준편차로 표시하였다. 결과: 4마리(20%)가 심부전에 의한 합병증으로 사망하였다. 이완기 말기 좌심실 체적은 측정시기에 따라 40.8$\pm$7.4, 82.1$\pm$21.1, 59.9$\pm$7.7, 46.5$\pm$6.5ml로 수축기말기 좌심실 체적과 비슷한 변화양상을 보였으며 심박출율은 50.6$\pm$4.1, 17.5$\pm$5.8, 36.3$\pm$7.3, 41.5$\pm$2.4%였다. 혈압과 맥박은 의의 있는 양상을 보이지 않았으며 중심정맥압, 우심실압, 폐동맥압, 폐동맥 쐐기압 등은 심부전 시에 의의 있는 증가를 보이다가 회복기에는 감소하는 양상을 볼 수 있다. 일회박출량은 21.5$\pm$8.2, 12.3$\pm$3.5, 17.9$\pm$4.6, 15.5$\pm$3.4ml으로 회복기에 심부전 상태로부터 회복하는 경향을 볼 수 있었다. 혈중 카테콜라민은 정상 133.3$\pm$60.0pg/dL에서 심부전 시에는 479.4$\pm$327.3pg/dL로 증가를 보였다(p=0.008). 결론: 빈맥을 이용한 심부전 모델은 외과적손상이 적고, 병의 정도를 임의로 조절할 수 할 수 있는 간편한 방법이다. 회복기에는 심기능 및 심장비대가 회복하는 경향을 보이므로 향후 새로운 술식의 평가를 위하여 회복 궤도를 이용하는 경우 실험 동물의 심부전 악화에 의한 사망율을 줄일 수 있는 새로운 방법이다.

An in vitro model providing with a recirculating perfusion apparatus using an isolated canine heart and its autogenous blood, which was prepared for study of myocardial protection method. This apparatus was easily used by quick connect system and maintained well heart function for about 2 hours. The Langendorff perfusion was initiated for a 10 minute period by introducing perfusate at 37` into the aorta from aortic reservoir located 100 cm above the heart. The isolated perfused working canine heart model was a left heart preparation in which oxygenated perfusion medium [at 37K] entered the cannulated left atrium at a constant flow rate [900ml/ min] under 20 mmHg overflow system and was spontaneously ejected[no electrical pacing] via an cannula against a hydrostatic pressure of 80 cm H2O. During this working period, various indices of cardiac function were measured. The cardiac functions were stable for over 2 hours with perfusion of Krebs-Henseleit solution and autologous blood[1:1] mixture in volume and maintained heart rate ]]3-122/bpm peak systolic pressure 109-113 mmHg, cardiac output 900 ml / min and left atrial mean pressure 8-9 mmHg. In this model, the efficiency of myocardia] protection could be easily measured by means of functional, enzymatic, biochemical and ultrastructural assessment. And also, we believe this model to be a useful assessment screening model of recovery state after long duration of myocardial preservation of donor heart without difficult transplantation procedures.

Recent experimental work indicates latamoxef sodium used as a broadspectrum antibiotics generates oxygen-free radicals. The present study represents an attempt to investigate whether reperfusate containing Shiomarin[85% latamoxef sodium+15% mannitol] might decrease the post-ischemic recovery of cardiac function. In the investigation, twelve isolated rat hearts were subjected to 270 minutes of cold total global ischemia. After the cold total global ischemia, six hearts[KHB group] were reperfused with Krebs-Henseleit buffer solution and the other six hearts[LMS group] with Krebs-Henseleit buffer solution containing latamoxef sodium[200ug /L]. Postischemic recovery rate of heart rate, aortic systolic pressure, aortic flow, coronary flow and cardiac output at 20 minutes reperfusion was 100.66$\pm$10.38, 85.25$\pm$7.61, 78.95$\pm$6. 02, 78.85$\pm$8.86 and 79.11$\pm$6.54 percent respectively in the KHB group and 97.96$\pm$4.19, 87. 72$\pm$4.37, 81.74$\pm$6.80, 82.69$\pm$10.01 and 81.90$\pm$6.67 percent respectively in the LMS group. The hemodynamic data revealed no significant difference in the post-ischemic recovery rate of the two groups. This finding suggests that reperfusate containing Shiomarin[latamoxef sodium, 200ug /L] does not affect the cardiac functional recovery after cold total global ischemia.
