  • Endomyocardial fibrosis(EMF) is an unusual type of cardiomyopathy characterized by a restriction to the ventricular filling and an obliteration of the inflow portion in the ventricular cavity by a fibrosis and often by a thrombus formation. The atrioventricular valve may be involved, resulting in an atrioventricular valvular regurgitation. The only known effective treatments are endomyocardiectomy and replacement of regurgitant AV valves. We report the experience of a case of EMF which required surgical management.

  • Essential thrombocytosis (ET) is a myeloproliferative disorder characterized by an anomalous increase in platelet production. Many patients with ET are asymptomatic. Few studies have reported ET-associated thromboembolism in large vessels such as the aorta. We report a patient with ET who presented with peripheral embolism from an abdominal aortic thrombus and developed acute limb ischemia. The patient underwent aortic replacement successfully. The patient's platelet count was controlled with hydroxyurea, and no recurrence was noted over 2 years of follow-up.

  • A 5-year-old boy was admitted to the hospital with a high fever and abnormal gait. Magnetic resonance imaging showed extensive swelling of the quadriceps and adductor muscles around the right hip and anterior thigh. A duplex scan demonstrated a thrombus from the external iliac vein to below the popliteal vein. The blood culture revealed Streptococcus pyogenes. The patient was immediately treated with antibiotics and anticoagulants. Follow-up sonography demonstrated complete disappearance of the venous thrombosis. We report a case of streptococcal myositis complicated by deep vein thrombosis.

  • Kawasaki disease is an acute systemic vasculitis of unknown origin. Giant coronary aneurysm is one of the most serious complications, although peripheral artery vasculitis can produce life-threatening events. Myocardial ischemia and infarction can be caused by coronary artery stenosis, aneurysm, and stagnation of blood flow in coronary arteries which triggers thromboembolism. Atypical presentation in young infants often interferes with prompt diagnosis and timely treatment, resulting in poor outcomes. We describe a 3-month-old infant with multiple giant coronary aneurysms with flow stagnation, stenosis and large mural thrombus due to Kawasaki disease. He presented with a prolonged course of severe coronary involvement in spite of all measures to reduce coronary complications. Finally, surgical intervention was tried because of the worsening coronary artery abnormalities. The patient died of acute cardiorespiratory failure shortly after weaning from cardiopulmonary bypass.

  • Six lumbrokinase (LK) fractions from Lumbricus rubellus lysates were purified by a series of column chromatographies. The molecular weights of the six LK fractions appeared to range from 24.6 to 33.1 kDa. In the experimental model of rat venous thrombosis, the thrombus weight and PAI activity decreased significantly when the LK was administered orally. However, the activities of APTT, PT and plasmin showed a significant increase. The aggregation of rat platelets pretreated with various LK doses was inhibited by thrombin, and the MDA generation decreased. The rat thoracic aorta and mesentric arteries contracted with phenylephrine relaxed due to the treatment of the LK fractions. These results suggest that the fibrinolytic effects of LK were mediated not only by proteolytic activity, but also by the inhibition of platelet agregation and the relaxation of blood vessels. It is concluded that the LK may be useful as a hemolytic agent for treatment of fibrin clot.

  • Alginase$Alginase^{ⓡ}$ (Arginine esterase) is one of the snake venoms which is mainly consisted of arginine esterase and acts as a thrombus -forming inhibitor/thrombus-lysin. These present studies were performed to investigate of the acute and subacute toxicity of the Alginase$Alginase^{ⓡ}$ in rats. In acute toxicity study, rats were single administered intravenously with dosages of 0.001, 0.01. 0.1, 1 and 10U/kg B.W. and examined the number of death, clinical sign, body weight and pathological change for 7days after administration of Alginase$Alginase^{ⓡ}$. At maximum dose level (10U/kg B.W.), Alginase$Alginase^{ⓡ}$ induced symptoms of shock with cyanosis and dyspnea. But these symptoms dissappeared after 30~50 minutes and we could not find any other toxic effect in rats. Therefore, $LD_{50}$ Value of Alginase was over 10U/kg B.W. in rats. In four-week intravenous toxicity study of Alginase$Alginase^{ⓡ}$, rats were administered intravenously seven days per week for 28 days, with dosages of 0, 0.0125, 0.125 and 1.25U/kg B.W./day, respectively. Alginase$Alginase^{ⓡ}$ did not caused any death and showed any clinical signs in rats. No significant Alginase$Alginase^{ⓡ}$ -related changes were found in feed uptake, water consumption, hematology, serum biochemistry, urinalysis, ocular examination, organ weight and histopathological examination. From the results, Alginase$Alginase^{ⓡ}$ seems not to have any toxic effect in rats when it were given daily intravenous injections below the dosage 1.25U/kg B.W./day for four weeks.

  • Fifty six mycelial cultured Basidiomycetes were screened for their inhibitory effects against prolyl endopeptidase(PEP), acetylcholine esterase(AChE) and thrombus coagulation. Out of them, methanolic extract of mycelium and/or ethylacetate(EtOAc) soluble fraction from culture broth of Peniophora quercina, Amanita aspera, Phellinus chrysoloma, Grifola frondosa, Wolfiporia extensa, Clavicorona pyxidata and Phanerochaete sordida inhibited more than 90% of PEP activity at 40 ppm. The extracts of Lenzites betulina, Phellinus chrysoloma, Wolfiporia extensa, Phanerochaete sorrlida, Hypocrea nigricans, Coriolus azureus, Flammulina velutipes, Phlebiopsis gigantea and Bondarzewia montana exhibited about 40% of inhibitory activity against AChE at 40 ppm. In thrombin times assay, the extracts of Amanita aspera, Oxyporus latemarginata, Peniophora quercina, Fomes fomenfarius, Trametes versicolor, and Phlebiopsis gigantea delayed coagulation of thrombus about two to three times over control at ca 550 ppm. In activated partial thromboplastin times assay, none of the tested Basidiomycetes showed significant effect.

  • Bypass surgery is performed for insuring continuity of a blood supply that is restricted due to obstruction of the native blood supply. Two types of surgery are commonly carried out: one is anatomic bypass and the other is extraanatomic bypass. Especially, extraanatomic bypass surgery is performed in patients who are a high risk for performing anatomical bypass surgery. The risk factors for anatomical bypass surgery are old age, infection, previous surgery and trauma. A 96-year-old patient underwent extraanatomic bypass surgery from the right femoral artery to the left femoral artery due to total occlusion of the left iliac artery, and 7 years after that operation, a pseudoaneurysm abruptly and spontaneously appeared from the bypass suture site without any predisposing factor. The lesion was revealed to be an organizing thrombus.

  • Objectives: This study examined the effects of 8 types of herbal prescriptions prescribed to alleviate dementia symptoms in a rat model of arterial thrombosis induced by ferric chloride ($FeCl_3$). Methods: Thirty minutes before 35% $FeCl_3$ treatment, SD rats were intraperitoneally injected with the 8 types of herbal prescriptions, respectively. We tested the effects of the herbal prescriptions on time to occlusion (TTO) in an arterial thrombosis model using a laser Doppler flow meter. In addition, thrombus weight (TW) and collagen fiber damages were evaluated in the same condition. Results: Herbal prescriptions showed the following rank-order based on their TTO: Chong-myung-tang (CMT) > modified Jangwonhan 02 (LMK02) > Toki-shakuyaku-san (TSS) ${\geq}$ Oren-gedoku-to (OGT) ${\geq}$ Yokukansan (YKS). In particular, CMT (100 mg/kg, i.p.) and LMK02 (100 mg/kg, i.p.) delayed the TTO the most ($14.83{\pm}0.98$ and $13.67{\pm}1.03$ min, respectively) compared with the vehicle group ($7.95{\pm}0.78$ min, P<0.001). In addition, CMT, LMK02, and OGT treatment ($0.63{\pm}0.01$, $0.66{\pm}0.02$ and $0.67{\pm}0.01$ mg/mm, respectively) significantly reduced thrombus weight compared with the vehicle treatment ($0.78{\pm}0.03$, P<0.001) and also alleviated collagen fiber damage (CMT; $28.40{\pm}2.22$%, LMK02; $30.79 {\pm} 4.07$%, OGT; $26.20{\pm}1.48$%) in the vessels injured by $FeCl_3$. Therefore, CMT and LMK02 showed the greatest preventive activity in rat model of arterial thrombosis induced by $FeCl_3$. Conclusions: These results provide experimental evidence for traditional use of herbal prescriptions, suggesting that CMT and LMK02 extracts could be used to prevent vascular injury and thrombosis in the early stages of dementia.
