During flap elevation, most perforators are cut except one or more perforators that are essential to flap survival. However these cutout perforators can cause deterioration of the blood circulation of the flap. To salvage the jeopardized flaps, rebuilding the perforator system is essential for flap survival. In the first case, after flap elevation, the upper abdominal flap margin was severely ischemic. To supply blood to the upper abdominal flaps, we found and used a major perforator underneath the upper abdominal flap which was cut earlier during the elevation, and we performed reanastomosis with ipsilateral deep inferior epigastric artery. Upper abdominal flap ischemic area was limited to a narrow suture area. In the second case, we performed free superficial inferior epigastric artery (SIEA) flap reconstruction. After successful anastomosis of the SIEA and superficial inferior epigastric vein (SIEV) with internal mammary artery and vein, serious venous congestion occurred immediately because of SIEV malfunction. We found the largest perforator vein under the flap, as an alternate way to drain, then connected it with the thoracoacromial vein with a vein graft harvested in the contralateral SIEV. Circulation has improved. In conclusion, perforator system reconstruction is essential in a jeopardized flap salvage.

Here we present the case of an 11-year-old female patient diagnosed with Caroli syndrome, who had refractory esophageal varices. The patient had a history of recurrent bleeding from esophageal varices, which was treated with endoscopic variceal ligation thrice over a period of 2 years. However, the bleeding was not controlled. When the patient finally visited the Emergency Department, the hemoglobin level was 4.4 g/dL. Transhepatic intrajugular portosystemic shunt was unsuccessful. Subsequently, the patient underwent percutaneous transhepatic variceal obliteration. Twenty hours after this procedure, the patient complained of aphasia, dizziness, headache, and general weakness. Six hours later, the patient became drowsy and unresponsive to painful stimuli. Lipiodol particles used to embolize the coronary and posterior gastric veins might have passed into the systemic arterial circulation, and they were found to be lodged in the brain, kidney, lung, and stomach. There was no abnormality of the portal vein on portal venography, and blood flow to the azygos vein through the paravertebral and hemiazygos systems was found to drain to the systemic circulation on coronary venography. Contrast echocardiography showed no pulmonary arteriovenous fistula. Symptoms improved with conservative management, and the esophageal varices were found to have improved on esophagogastroduodenoscopy.

Diabetes is a controllable disease, not a curable disease. If Diabetic patients do not regularly monitor themselves, they run risk of diabetic complications that cannot be reversed or treated. Especially, if the patients have high blood suger level, a cardiovascular disease, or poor blood circulation, there immune system will not function, and thus making the patient more susceptible to infection. Eventually, the patient will have to undergo amputation. The case is a report about a Diabetic patient with foot ulcers. The patient was treated by Taeumin Bopyewontang and the foot ulcers were improved.

Objective: Coenzyme (CoQ10) is an enzymatic co factor used in normal cellular metabolism. Recent evidence shows that in people with heart disease it can reverse endothelial cell damage in the blood vessels. It is also a potent antioxidant. Design: One group pretest-posttest design. Methods: In the present study, endothelial function was evaluated using the response to occlusion and heat before and 2 weeks after administration of CoQ10, 300 mg/day. Thirty Eight subjects, who are physical therapy students, participated in a series of experiments to see if taking 300 mg of CoQ10 daily for 2 weeks would impact resting blood flow in the forearm skin and the blood flow response to 4 minutes of vascular occlusion and the response to local heat ($42^{\circ}C$) for 6 minutes. Results: The results showed that, for this population, there was no difference in the response to heat. However, the response to occlusion was improved after administration of CoQ10. Conclusions: It would appear that in a young population CoQ10 has no effect on the nitric oxide vasodilator pathway in skin but does influence other vasodilator pathways.

A splanchic artery occlusion for 90 min followed by reperfusion of the mesenteric circulation resulted in a severe form of circulatory shock characterized by endothelial dysfunction, severe hypotension, marked intestinal tissue injury, and a high mortality rate. The effect of rutin, a flavonoid having antiprostanoid, anti-inflammatory, antithrombotic, antioxidant effect, were investigated in a model of splanchnic artery occlusion (SAO) shock in urethane anesthetized rats. Occlusion of the superior mesenteric artery for 90 min produced a severe shock state resulted in a fatal outcome within 120 min of reperfusion in many rats. Rutin was given as a bolus (1.28 mg/kg) 10 min prior to reperfusion. Administration of rutin significantly improved mean arterial blood pressure in comparison to vehicle treated rats (p＜0.05). Rutin treatment also resulted in a significant attenuation in the increase in plasma amino nitrogen concentration, intestinal myeloperoxidase activity, intestinal lipid peroxidation, infiltration of neutrophils in intestine and thrombin induced adherence of neutrophils to superior mesentric artery segments. These results suggest that rutin provides beneficial effects in part by preserving endothelial function and attenuating neutrophil accumulation in the ischemic reperfused splanchnic circulation.

A splanchic artery occlusion for 90 min followed by reperfusion of the mesenteric circulation resulted in a severe form of circulatory shock, characterized by endothelial dysfunction, severe hypotension, marked intestinal tissue injury, and a high mortality rate. The effect of defibrotide, a complex of single-stranded polydeoxyribonucleotides having antithrombotic effect, was investigated in a model of splanchnic artery occlusion (SAO) shock in urethane anesthetized rats. Occlusion of the superior mesenteric artery for 90 min produced a severe shock state, resulting in a fatal outcome within 120 min of reperfusion in many rats. Defibrotide (10 mg/kg body weight) 10 min prior to reperfusion significantly improved mean arterial blood pressure in comparison to vehicle treated rats (p＜0.05). Defibrotide treatment also significantly attenuated in the increase of plasma amino nitrogen concentration, intestinal myeloperoxidase activity, intestinal lipid peroxidation, infiltration of neutrophils in intestine and thrombin induced adherence of neutrophils to superior mesentric artery segments. Superoxide anion and hydrogen peroxide production in $1{\mu}M$ formylmethionylleucylphenylalanine (fMLP)-activated PMNs was inhibited by defibrotide in a dose-dependent fashion. Defibrotide effectively scavenged hydrogen peroxide, but not hydroxyl radical. Treatment of SAO rats with defibrotide inhibited tumor necrosis factor-${\alpha}$, and interleukin-1${\beta}$ productions in blood in comparison with untreated rats. These results suggest that defibrotide partly provides beneficial effects by preserving endothelial function, attenuating neutrophil accumulation, and antioxidant in the ischemic reperfused splanchnic circulation

순환계는 혈액의 흐름이 원활하게 되도록 그 해부학적 구조와 혈류의 물리학적 특성이 연결되어있다. 혈액의 흐름에 영향을 주는 혈액의 물리학적 특성을 혈유변학적 인자(Hemorheologic factors)라 하며, 혈액의 점도(blood viscosity) 및 적혈구 응집도(erythrocyte aggregation)와 같은 혈유변학적 특성은 헤마토크리트(hematocrit; Hct)와 밀접한 관계를 가진다. 헤마토크리트가 높을수록 혈액 점도가 증가하고 적혈구 응집도는 증가하며 순환을 저해하고 조직에 산소 전달 능력을 방해한다. 혈청 페리틴은 과도하게 있을 경우 산화유리기(oxygen free radial)를 통하여 혈관 내피세포(vascular endothelial cell)와 혈구 세포(blood cell)에 산화 손상을 유발하여 심혈관계 손상을 유발한다. 이러한 기전을 근거로 사혈 혹은 헌혈을 심혈관계 질환의 예방 및 치료에 응용하려는 시도가 오랫동안 있었다. 사혈은 의학에 있어 오랜 역사를 가지면서 특히 한방의 치료적 개념으로 최근까지도 사용되고 있으나 그 과학적 근거가 불충분하고 아직까지 논란의 여지도 있어 근거 중심의 의학을 근간으로 하는 의학에서는 도외시되어왔다. 하지만 혈액량이 증가하면 혈유변학적 인자들(hemorheological factors) 역시 악화되면서 대 순환에서 동맥경화의 발생 및 진행에 영향을 주고, 모세순환(microcirculation)을 악화시키는 것으로 알려져 있으며 심뇌혈관 사건에 영향을 주는 것으로 보고되고 있다. 정기적인 헌혈자(regular blood donors)에게 혈유변학적 인자들을 저명하게 호전시키고 과도한 철분의 함량을 줄여서 산화유리기에 의한 혈구 및 내피세포의 산화 손상을 줄임으로써, 순환계내에서 혈액순환을 촉진시킬 수 있다는 증거들이 보고되고 있다. 헌혈의 효과가 심혈관계 질환에 이익이 된다는 확고한 장기적 코호트 연구결과가 도출된다면 절대적으로 헌혈 혈액량이 부족한 현실과 심혈관계 질환의 예후를 호전시킬 수 있다는 측면에서 중요한 역할을 할 수 있다고 생각된다.

The root powder of Angelicae gigantis Radix (RPAGR) is known to he beneficial for liver and blood circulation. In a 6-wk broiler feeding trial, the RPAGR was added at levels of 0, 0.2, 0.5, and 1.0%, respectively. The RPAGR was found to be palatable as birds consumed moreof the test diets than the control(0% RPAGR) diet. The BW gain of 1.0% RPAGR group was higher than the control group. The feed efficiency(F/G) was improved significantly(P<0.01) by feeding 1.0% RPAGR. The RPAGR also caused beneficial effects in various carcass characteristics, i.e., carcass weight, dressing percentage, breast muscle, and thigh meat production. There was no consistent trend in various organ weights by the addition of RPAGR. Also, no consistent trend was found in abdominal fat weight. The serum cholesterol level tended to decrease as the BW increased. No consistent trend was detected in serum triglyceride contents.

The effect of compression wear for sport performance and muscle function was investigated based on the physiological test and electromyograph(EMG). The EMG test was used to study muscle activity after fitting the compression wear during exercise. It showed slight difference between men and women testee groups in the results of anaerobic, aerobic, fatigue, and EMG test due to muscle content in the body. In addition, the exercise performance was increased to some extent even the muscle activity was decreased. It is estimated that the compression effect to muscle by the compression wear decreased the muscle vibration and improved blood circulation which helped the entire sport performance. However, it is necessary to study the effect of compression wear in long-term wearing in the future study.
