  • Effects of Nattokinase fibrinol (NKF), defined as a fibrinolytic product, on fibrinolytic and atherogenetic markers were studied for healthy adults (20-31 years old), who is smoking more than 20 cigarettes per day. Subjects were divided into 29 for NKF group and 10 for placebo group in a short term study. They were given 2 tablets of NKF (4,000 unit) or placebo tablet and thereafter blood samples were collected at 0, 2, 4 hr prerid. For a 4-week long term study, 15 subjects for NFK group and 10 subjects for placebo group were supplemented one tablet of each NKF (2,000 unit) and placebo per day, respectively. Blood samples were collected at 0, 1, 2, 4 weeks later. The short-term experimental trial showed that NKF remarkably increased fibrinolytic activity at 2hr after consumption, which was maintained up to 4 hr, relative to that of placebo, while NKF reduced the euglobulin clot lysis time (ECLT) and retarded the activated partial thromboplastin time (aPTT), as compared to placebo group. NKF supplementation for 4 weeks elevated fibrinolytic activity, shortened ECLT and retarded aPTT. Furthermore, NKF supplementation increased anti-atherogenic index by decreasing triglyceride (TG) and elevating high-density lipiprotein (HDL)-cholesterol. These results indicate that NKF supplementation for short term or long term might have beneficial effects on preventing and treating cardiovascular disease by increasing fibrinolytic activity and improving atherogenic markers such as hyperlipidemia.

  • Intermaxillary fixation is routine procedure to oral and maxillofacial area in jaw bone fracture, surgical correction of jaw deformity, osseus reconstruction of jaw. After transoral surgery, accompanied by intermaxillary fixation, dysphagia or airway obstruction may be followed due to blood clot, vomitus, or laryngeal spasm resulting from irritation by blood or secretions. Lingual or pharyngeal edema is other contributing factors of airway obstruction. In addition, intermaxillary fixation itself may cause obstruction of airway. In this study, pulmonary function test and arterial blood gas analysis were evaluated before and after intermaxillary fixation in 30 patients suffered from mandibular fractures. Comparative analysis was performed by estimated values. The results were as followed. 1. The spirometric values of FEV1, FEV1/FVC and FEF25-75% without intermaxillary fixation were reduced from 97.57%, 85.1%, 98.3,% to 71.7%, 66.5%, 61.2% with intermaxillary fixation, indicating the presence of obstructive pulmonary impairment. 2. Spirometric value of MVV, as the most influencing value of sensitive to extrapulmonary factors, was changed from 84.5% to 46.48%. 3. After intermaxillary fixation, the spirometric value of FVC, as indicator of restrictive pattern of pulmonary function, was not reduced significantly as measured from 94.47% to 89.97%. 4. $O_2$ saturation of arterial blood gas analysis without intermaxillary fixation was 97.86%. While intermaxillary fixation, $O_2$ saturation was 97.47%. The results indicate that careful airway management is mandatory undergoing intermaxillary fixation of various oral and maxillofacial surgery.

  • This experiment was carried out to study the preventive effect of cysteine on the toxicities of captafol to the hematological and serum biochemical values. A single dose of captafol(5mg/kg BW, ip) was given to male Sprague-Dawley rats and its toxicities were evalutated by body weitht changes, autopsy findings, absolute organ weight, and hematological and serum biochemical parameters. The single dose of captafol caused significant decreases in body weitht, and absolute liver weight, as-cites, fibrin clot in abdominal cavity, adhesion of liver lobes significant elevation of number of RBC, hemoglobin concentration and serum AST activity, and decreased of serum phospholipid level. Where as cysteine(over 58mg/kg BW) given immediately after captafol appeared to prevent the ascites, fibrin clot in abdominal cavity and liver lobe adhesion. It also prevented the liver and blood, especially RBC toxicites. The results suggest that cysteine and other compounds containing sulfhydryl groups may protect the subjects from captafol-induced toxicity.

  • Maxillary sinus lift for dental implant installation is a well-known and versatile technique; new techniques are presented based on the physiology of intrasinus bone repair. The aim of this review was to determine the status of graftless maxillary sinus lift and analyze its foundations and results. A search was conducted of the literature between 1995 and 2015 in the Medline, ScienceDirect, and SciELO databases using the keywords "maxillary sinus lift," "blood clot," "graftless maxillary sinus augmentation," and "dental implant placement." Ten articles were selected for our analysis of this technique and its results. Despite the limited information, cases that were followed for at least six months and up to four years had a 90% success rate. Published techniques included a lateral window, elevation of the sinus membrane, drilling and dental implant installation, descent of the membrane with variations in the installation of the lateral wall access and suturing. The physiology behind this new bone formation response and the results of the present research were also discussed. We concluded that this is a promising and viable technique under certain inclusion criteria.

  • 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.

  • The anti-thrombotic effects of LB30057, a direct thrombin inhibitor, were evaluated with in vivo rat and dog thrombosis models. In rats, 1 mg/kg of LB30057 inhibited half of the clot formations in the inferior vena cava at 5 minutes after intravenous application. When measured at 2 hours after oral application, 100 mg/kg prevented approximately half of the clot formations in the inferior vena cava and 50 mg/kg prolonged the mean occlusion time from $15.6{\pm}1.3$ minutes to $47.2{\pm}8.3$ minutes in the carotid artery. In dogs, the formation of thrombus in the jugular vein was reduced to half at a dose range of 20-30 mg/kg at 6 hours after oral application. In addition, the LB30057 dosage required to reduce venous clot formation by approximately 80-90% in dogs was only about 10% of that required for the same reduction in rats. This is probably due to the variation in its time-dependent blood concentration profiles in each species; for example, the plasma half-life of LB71350 in dogs was longer than that in rats ($153.0{\pm}3.0$ vs. $129.7{\pm}12.7$ min at 30 mg/kg, i.v., respectively). AUG, $T_{max},{\;}G_{max}$, and BA in dogs were 59, 8.9, 9.17, and 13.3 times higher than those in rats at oral 30 mg/kg, respectively. Taken together, these results suggest that LB30057 administered orally is effective in the prevention of arterial and venous thrombosis in rats and dogs. It therefore represents a good lead compound for investigations to discover a new, orally available, therapeutic agent for treating thrombotic diseases.

  • A 14-year-old intact female Cocker Spaniel dog, weighing 6.8 kg, presented with chief complaints of severe cough, dyspnea, anorexia, and exercise intolerance. It had the characteristics of a blood clot, the evidence of mitral regurgitation, a high left atrial/aortic root ratio, and pericardial effusion with a left atrial rupture due to myxomatous mitral valve degeneration (MMVD) was strongly suspected. Traditional therapy (pimobendan, furosemide, enalapril, and spironolactone) for heart failure with MMVD was provided twice a day orally, and partial pericardiectomy was performed for pericardial effusion. The medical prescriptions for MMVD were continued, and the patient's heart disease was well-controlled. However, it suddenly died 3 months after the operation.

  • Antithrombotic and fibrinolytic activity of natto was evaluated on platelet aggregation in vitro and in vivo. Natto showed inhibitory effects on platelet aggregation induced by adenosine 5’diphosphate (ADP) and collagen. Orally administered natto also showed fibrinolytic activity in hypercholesterolemia rats. Normal levels of natto, when administered for four weeks, shortened euglobulin clot lysis time (ECLT) and prolonged partial thromboplastin time (PATT) significantly compared to non-treated group. In addition, the natto treatment decreased total cholesterol in serum. These results showed that intake of normal levels of natto can elicit antithrombotic and fibrinolytic effects, suggesting its consumption may improve blood circulation.

  • Pulmonary thromboembolism originated most commonly from the venous thrombus, especially deep vein thrombus in the leg, which migrated to and occluded the pulmonary vasculatures. The failure of clot lysis and repeated embolic episodes resulted in the hemodynamic compromise -that is- in the increasing in the pulmonary vascular resistance, which would cause the right ventricle failure[Car Pulmonale]. Under the cardiopulmonary bypass, 20 year old male patient was treated successfully by thromboembolectomy of pulmonary thromboembolism with pulmonary hypertension, which originated from the deep vein thrombus in the leg. The results of radiologic studies and clinical evaluations were excellent in that the postoperative lung perfusion scan showed the newly increased perfusion of post-embolectomy territories and in the arterial blood gas finding of 76 from 66[mmHg] in PaO2. The patient was uneventful and discharged on postop. $ 14 days with anticoagulant continued.

  • Regenerative endodontic procedure (REP) is a treatment option to replace damaged pulp tissue with the viable tissue which restores the normal function of the pulp-dentin complex. Possible reason for doing REP is not clearly known, however, clinicians perform REP in order to recover the histological structure as well as function of the traumatized and diseased tooth so that this tooth can restore its original root shape and thickness. This REP can be explained by the concept of revascularization or revitalization after induction of blood clot formation in the canal space. For this purpose, several treatment strategies have been suggested. In this regard, the rationale for the application of triantibiotics, calcium hydroxide or mineral trioxide aggregate is discussed in this paper. As a result, we will try to find the best method for REP by reviewing each available technique and their advantages and disadvantages.
