  • Blood coagulation time, bleeding time, clot retraction ability, thrombocytes counts and hematological values under electroacpuncture anesthesis and medicament anesthesia, using 10 mongrel dogs were compared. The results were summarized as follows: 1. Blood coagulation time under electroacupuncture anesthesia was shorter than that under medicament anesthesia (p<0.001). 2. Bleeding time under electroacupuncture anesthesia was shorter than that under medicament anesthesia (p<0.01). 3. Clot retraction ability under electroacupuncture anesthesia was better than that under medicament anesthesia (p<0.01). 4. Thrombocytes counts under electroacupuncture anesthesia was more increased than that under medicament anesthesia (p<0.05). 5. Erythrocytes counts, hematocrit values, hemnglobin contents and leukocytes counts were decreased (p<0.01) under medicament anesthesia in comparison with control group, but there was no significant difference under electroacupuncture anesthesia.

  • Green tea catechins(GTC) were studied for its inhibitory effect on human platelet aggregation in vitro, for its antithrombotic effect in mice in viro, and bleeding and clotting time in rats. The catechins were isolated and purified from green tea, which were composed of (-)-epigallocatechin gallate, (-)-epigallocatechin, (-)epicatechin gallate and (-)-epicatechin, GTC produced a potent inhibition of human platelet aggregation in a dose-dependent manner against the stimulants such as ADP, collagen, epinephrine and ristocetin n vitro. GTC also prevented death due to the formation of pulmonary thrombosis by platelet aggregates in mice in a dose-de-pendent manner in viro. GTC increased the bleeding time, whole blood clotting time and plasma clotting time in rats, too. These results suggest that GTC is a promising antithrombotic agent.

  • This study is intended to investigate the influence of chemical admixture on bleeding of concrete. According to the results, the amount of bleeding with elapse of time does not make much difference in the case of naphthalene type water reducing agent(RN), Naphthalene type high performance water reducing agent(HN) and Melamine type high performance water reducing agent(HM), but it is largest in the case of Polycarbonic acid type high performance water reducing agent(HP). Bleeding speed also is highest in the case of HP in comparison with other chemical admixture. This prove that high performance water reducing agent like HP has little effect on fluidity of concrete, but influences the amount of bleeding more greatly, instead. As properties of hardened concrete, compressive strength makes no difference in the case of RN, HN and HM, but on the other hand, it increases in the case of HP due to a decrease of air content and the large amount of bleeding.

  • Objectives: The purpose of the study is to investigate the factors associated with gingival bleeding(GB) by tooth brushing in college students. Methods: A self-reported questionnaire was filled out by 232 college students in Daegu Health College from March to June, 2014. Data were analyzed for frequency, chi square test, and logistic regression analysis using SPSS 12.0 program. The study was a cross sectional study. The questionnaire consisted of general characteristics of the subjects(gender, age, marital status, and smoking), frequency and duration of tooth brushing, scaling experience, and physical health status. Self-reporting hemorrhage was reported by yes or no. Frequency of tooth brushing was documented as the number of behavior. Above 4 times of tooth brushing was defined as 4. Duration of tooth brushing was documented as minute. Above 4 minutes, it was recorded as 4. In physical health status, 1 is feeling weak and 4 is feeling very healthy. Cronbach alpha was 0.82 in the study. Results: There were significant relationships between gingival bleeding and age(p<0.05), subjective health(p<0.01), tooth brushing frequency(p<0.05) and duration(p<0.05) by chi square test. Logistic regression analysis showed that the age(p<0.05), subjective health(p<0.01), tooth brushing frequency(p<0.05) and duration(p<0.05) were associated with gingival bleeding. Prevalence of gingival bleeding in 20 years was 0.62(odds ratio 1.85, 95% CI 1.00~3.43) and it was higher than that in 10 years. Prevalence of gingival bleeding in good health group was -1.38 and it was lower than that in poor health group. Conclusions: The factors associated with gingival bleeding were age, subjective health, and tooth brushing frequency and time.

  • Postoperative gastrointestinal bleeding is a rare but serious complication that can lead to prolonged hospitalization and significant morbidity and mortality. It can be managed by reoperation, endoscopy, or radiological intervention. Although reoperation carries risks, particularly in critically ill postoperative patients, minimally invasive interventions, such as endoscopy or radiological intervention, confer advantages. Endoscopy allows localization of the bleeding focus and hemostatic management at the same time. Although there have been concerns regarding the potential risk of creating an anastomotic disruption or perforation during early postoperative endoscopy, endoscopic management has become more popular over time. However, there is currently no consensus on the best endoscopic management for postoperative gastrointestinal bleeding because most practices are based on retrospective case series. Furthermore, there is a wide range of individual complexities in anatomical and clinical settings after surgery. This review focused on the safety and effectiveness of endoscopic management in various surgical settings.

  • Objectives: In the past, the pharmaceutical drug heparin was mostly used as the anticoagulant for continuous renal replacement therapy (CRRT), but the duration time is long to have the risk of a bleeding adverse effect, and in that case the drug therapy Nafamostat mesilate was utilized instead, as it is more safe in this case, with a short half-life and is increasing in use to permit lower concerns for bleeding incidents. However, there are insufficient number of large-scale studies on the comparison of Nafamostat mesilate and heparin. Methods: In this study, a systematic review are used to compare the bleeding risk of Nafamostat mesilate and Heparin, as subjected to patients and procedures for measuring risks performed with a CRRT, and the filter life span is to be evaluated as well in this patients. Results: As a result of literature review search, a total of 6 studies were included in systematic review. The reducing risk of bleeding and filter life span was analyzed. The retrospective cohort studies confirm that Nafamostat mesilate is less at risk of bleeding than heparin. And a cohort study confirms that Nafamostat mesilate is longer filter lifespan than heparin and randomized controlled trial studies show that Nafamostat mesilate is longer filter lifespan than not using the anticoagulants. Conclusion: Nafamostat mesilate is considered to be a good therapeutic option because it has a longer filter life span as well as the advantage of reducing bleeding.

  • Purpose: This study was conducted to compare pain, sense, bleeding, and hematoma that patients feel depending on the process of eliminating air of pressure band that was applied to patients after percutaneous coronary intervention (PCI) through radial artery. Methods: It was a nonequivalent control group pretestposttest design to compare pain, sense, bleeding, and hematoma by amount and time of eliminating air of pressure band after PCI through radial artery. Results: On arrival at Coronary Care Unit, meaningful difference didn't exist between pain and sense, however, after two hours of starting eliminating air, the points of pain and sense were meaningfully low (p<.001). Also, there was meaningful difference in reciprocal action between group and time (p<.001). Conclusion: After PCI, the conclusion showed there is positive effect in decreasing wrist pain and sense without any influence of bleeding by eliminating air from patients' pressure bands.

  • Background: N-Butyl Cyanoacrylate (NBCA) is a liquid embolic material that can be useful for transcatheter arterial embolization (TAE) of acute bleeding especially in patients with coagulopathy, because it does not depend on coagulation for its therapeutic effect. The aims of this study were to evaluate the clinical efficacy and safety of TAE with NBCA in acute bleeding patients. Methods: Between August 2003 and September 2004, TAE using NBCA for acute bleeding was performed in 23 patients (16 men, 7 women; mean age, 56.5years). The causes of bleeding were gastric ulcer (n=5), postoperative bleeding (n=4), post-biopsy bleeding (n=3), postpartum bleeding (n=3), duodenal ulcer (n=2), angiodysplasia (n=2), gastric lymphoma (n=1), iatrogenic injury (n=1), CMV gastritis (n=1), stab injury of the liver (n=1). TAE was performed using 1:3 mixtures of NBCA and iodized oil. The angiographic and clinical success rate, recurrent bleeding rate, procedure-related complication and clinical outcomes were evaluated. Results: The angiographic and clinical success rate was 100% and 91.3% (21/23), respectively. There was no serious ischemic complication. Recurrent bleeding occurred in 2 patients (8.7%) and they were managed with successful second TAE (n=1) and endoscopic treatment (n=1). Nine patients (39.1%) had coagulopathy at the time of TAE and clinical success rate in this group of patients was 88.9% (8/9). Conclusions: TAE with NBCA is highly effective and safe treatment modality for acute bleeding patients, especially when the patient has a coagulopathy.

  • Background: Venous thromboembolism (VTE) is a common and life-threating condition in cancer patients. Low molecular weight heparins (LMWH), such as dalteparin, are recommended in the treatment of VTE. Also, rivaroxaban, an orally administered direct factor Xa inhibitor, was approved for the treatment of VTE. It showed similar efficacy to standard therapy (LMWH or warfarin) and was associated with significantly lower rates of major bleedings. However, in the real world, bleeding has been reported to occur frequently in cancer patient receiving rivaroxaban. The goal of this research was to analyze bleeding risks between rivaroxaban and dalteparin for treatment of VTE in cancer patients. Methods: Medical records of oncology patients who were treated with rivaroxaban or dalteparin for VTE from July 2012 to June 2014 were retrospectively reviewed. Data collected were as follows: age, sex, weight, height, cancer types and stages, ECOG (eastern cooperative oncology group) PS (performance score), VTE types, concurrently used medications, study drug information (dose and duration of therapy), INR (international normalized ratio), PT (prothrombin time), and platelet counts. Bleeding was classified into major bleedings, clinically relevant non-major bleedings, and minor bleedings. Results: A total of 399 patients were included in the study. Of these patients, 246 were treated with rivaroxaban and 153 with dalteparin. Bleeding rates were significantly higher in the rivaroxaban group than in the dalteparin group (adjusted odds ratio (AOR) 2.09, 95% CI 1.22-3.60) after adjusting for confounders. In addition, rivaroxaban remained independently associated with 1.78-fold (95% CI 1.14-2.76) shorter time to bleeding compared to dalteparin after adjusting other factors known to be associated with poor outcomes. Conclusion: This study suggested that rivaroxaban was associated with an increased risk of bleedings in cancer patients.
