The present experiments were designed to investigate the effects of BangPoongSan on the cardiovascular system in the experimental Animals. And thus the change of blood pressure, auricular blood flow, artery contraction, death rate, platelet aggregation repression, plasma coagulation factor activity, plasma antithrombin activity, whole blood viscosity and plasma viscosity were studied. The result were summarized as the followings: 1. BangPoongSan dropped the blood pressure in the spontaneous hypertensive rat. 2. The drug increased the auricular blood flow in rabbit. 3. The drug relaxed the artery contraction by pretreated norepinephrine in white rat. 4. The drug inhibited the death rate of mouse which was led to thromboembolism by serotonin and collagen. 5. The drug inhibited the platelet aggregation in rat. 6. The drug prolonged the prothrombin time and activated partial thromboplastin time on the test of plasma coagulation factor activity in rat, but was not valuable. 7. The drug presented the antithrombin activity in rat. 8. The drug reduced the whole blood viscosity and plasma viscosity in rat, but the latter was not valuable. According to the results, Bangpoongsan increased the blood flow and dropped the blood pressure by dilatation of blood vessel smooth muscle. And the drug presented the antithrombin acivity, inhibited the platelet aggregation and reduced blood viscosity. Therefore these effects are assumed to improve the cardiovascular circulation disorder and prevent thrombosis.

The clotting assay was replaced by the chromogenic substrate assay which is recommended by the European Pharmacopoeia (EP) and the Scientific and Standardization Committee of the International Society on Thrombosis and Haemostasis based on the reliability convenience and simplicity of the chromogenic assay, A correlation study was carried out with a one-stage factor Ⅷ : C clotting assay and the performance of the chromogenic assay was evaluated using two test kits that fulfilled the requirements of EP for factor Ⅷ concentrates test. Although chromogenic assay has partly differences in measurement principle and standardization, this assay has a high correlation with clotting assay in various types of factor Ⅷ concentrates and factor Ⅷ standard. We conclude that the chromogenic assay for factor Ⅷ : C concentrates correlates well with the clotting assay and shows good analytical performance.

Objectives: The study aimed to determine changes in laboratory data for cancer patients receiving Korean medicine (KM) care, with a focus on patients' functional status, cancer-coagulation factors and cancer immunity. Methods: We conducted an observational study of various cancer patients in all stages admitted to the East-West Cancer Center (EWCC), Dunsan Korean Hospital of Daejeon University, from Mar. 2011 to Aug. 2011. All patients were under the center's multi-modality Korean-medicine-based inpatient cancer care program. The hospitalization stay at EWCC ranged from 9 to 34 days. A total of 80 patients were followed in their routine hematologic laboratory screenings performed before and after hospitalization. Patients were divided into three groups depending on the status of their treatment: prevention of recurrence and metastasis group, KM treatment only group, and combination of conventional and KM treatment group. The lab reports included natural killer cell count (CD16 + CD56), fibrinogen, white blood cell (WBC), lymphocytes, monocytes, neutrophil, red blood cell (RBC), hemoglobin, platelet, Erythrocyte Sedimentation Rate (ESR), and Eastern Cooperative Oncology Group (ECOG) performance status. Results: With a Focus on patients' functional status, cancer-coagulation factors and cancer immunity, emphasis was placed on the NK cell count, fibrinogen count, and ECOG scores. Data generally revealed decreased fibrinogen count, fluctuating NK cell count and decreased ECOG, meaning improved performance status in all groups. The KM treatment only group showed the largest decrease in mean fibrinogen count and the largest increase in mean NK cell count. However, the group's ECOG score showed the smallest decrease, which may be due to the concentration of late-cancer-stage patients in that particular group. Conclusions: Multi-modality KM inpatient care may have positive effect on lowering the cancer coagulation factor fibrinogen, but its correlation with the change in the NK cell count is not clear.

Algae causes not only the eutrophication of lake, but also the deterioration of drinking water process. Especially, algogenic organic matters(AOM) are assumed as disinfection by-products(DBPs) precursors like humic and fulvic acids. In this study, it was investigated the characteristics changes of algogenic organic matter(AOM) by prechlorination and coagulation treatment. Evaluation of enhanced coagulation and applicability of UV oxidation process were also evaluated as the drinking water treatment system for the eutrophicated water source. prechlorination was effective process for algae removal but caused releasing of dissolved organic matter(DOC) into water due to the destruction of algae's cell. In coagulation treatment with Fe(III) coagulant, reaction pH is an important factor for the removal of AOM and triholomathanes(THMs). At pH 5, removal efficiency of DOC and THMs were dramatically improved by 50% and 28%, respectively, in comparison with the conventional coagulation treatment at about pH 7. Photo-Fenton($UV/H_2O_2/Fe^{3+}$) process among the UV oxidations is the most effective system to remove AOM, but its removal efficiency was lower than that of enhanced coagulation treatment at pH 5.

We investigated the effect of seatangle drink and seatangle extract on lipid oxidation, blood coagulation and intestinal movement in rats fed a hyperlipidemic diet. In the dietary hyperlipidemic induced group, the serum superoxide dismutase activity decreased and formation of hydroxy radical increased when compared to normal group, but these were controlled by seatangle drink treatment. The decreased of bleeding time and increased of tissue factor in the dietary hyperlipidemic rats were regulated by seatangle drink and seatangle extract, and especially the activity of tissue factor was remarkably decreased. Seatangle drink and seatangle extract were increased contraction on intestinal movement. Therefore, it can be concluded that seatangle drink or seatangle extract treatment depresses changing in absorption of gastrointestinal track in rats fed a hyperlipidemic diet.

Hemophilia is the most common coagulation disorder. It has a long history. Hemophilia A is caused by FVIII gene mutation, and hemophilia B by FIX gene mutation. Those genes are located on X chromosome long arm. Bleedings in hemophiliacs predominantly occur in joints and muscles. Because those site are insufficient in tissue factor to induce hemostasis. Among joints knee, ankle and elbow are most frequently affected because their synovial structure is vulnerable to injury compared to other joints. Hemophilia is diagnosed with factor assay. Severe hemophilia is below 1% of FVIII : C, moderate between 1% and 5%, mild over 5%. Carrier detection and prenatal diagnosis have been conducted with RFLP-based linkage analysis and DNA sequencing. Mainstay of treatment is factor replacement therapy so far. Bleedings can be controlled by infusion of factor concentrates. Hemophilc arthropathy and muscle contracture are representative sequelae. Complications of facotor replacement therapy are inhibitor development and infections. Hemophiliacs with inhibitor should be managed with large dose factor concentrate, bypassing agent, ITI and immunosuppression. Ultimately, hemophilia could be cured by gene therapy.

Bokbunja (Rubus coreanus) is a Korean fruit and wild black raspberry that has antioxidant, anticancer, and beauty effects due to its abundant polyphenols and anthocyanins. The purpose of this study was to investigate the blood flow improvement effect of Bokbunja seed oil (BSO) in a high-fat diet-fed mouse model. We examined improvement of blood flow and its related biomarkers in vivo. Mice were divided into four groups; Control, high fat diet control (negative control, HFD), salmon oil control (positive control, HFD+commercial n-3 fatty acid), and BSO experiment groups (HFD+2 g/2,000 kcal, HFD+4 g/2,000 kcal). After the mice were sacrificed, plasma triglyceride, cholesterol, and blood flow-related biomarkers (coagulation factor 7, 12, serotonin, TXB2, PT, and aPTT) were measured in mouse blood and organs. BSO reduced blood viscosity through improvement of blood lipids (cholesterol and plasma triglycerides) as well as levels of blood coagulation factors and blood platelet activity. BSO also delayed blood coagulation time. Thus, we confirmed that BSO inhibits excessive blood clotting of blood vessels and improves blood flow. Taken together, these results suggest that BSO decreases plasma triglycerides and cholesterol and improves blood flow by regulating biomarkers.

Hemophilia B is hereditary disorder of blood coagulation known as a deficiency of P.T.C. or Christmas factor. Anyway it's indistinguishable clinically with hemophia A and C. Here's one of most interesting problems gave us because we could only find it out as a hemophilia B. when we stood a situation to be met continuous bleeding from the operative wound of tonsillectomy and Adenoidectomy. Wintrobe proposed that easy bruising, difficulty in stopping the bleeding from razor cuts, and prolonged bleeding after tonsillectomy or tooth extraction usually are the major manifestations. For a long time little attention was paid to reports of a milder form of the diseases. In such cases coagulation time, and even prothrombin consumption were normal and the symptoms were correspondinly mild, small wounds as a rule giving little trouble and hemoarthrosis being uncommon. In our cases, there's no specific contributory history except nasal bleeding intermittently and also no specific contributory laboratory data before the operation. After the T. & A., there's continuous bleeding from nasopharynx and the coagulas on the both tonsilar fossas being grown day by day. Therefore we suspected some abnormality of coagulation mechanism and then we could get conclusion of hemophilia B. after various laboratory tests including T.G.T., As I know, this case, hemophilia B. is 3rd one as a report in Korea. We have no data of hemophilia family at present time, so that I propose that we have to make system of hemophilia family in Korea. In a next, we have to make routinely complete laboratory test, ego routine C.B.C., bleeding time, coagulation time, prothrombine time, partial thromboplastine time, before operation of T.& A. If we can solve these problems we can get the T. & A. without any problems of bleeding according to get the operation of T. & A.

Purpose: Congenital factor VII (FVII) deficiency is a rare bleeding disorder and surgery can cause excessive bleeding due to an extrinsic pathway problem. It can be diagnosed by increased PT and decreased FVII level in coagulation test. Symptom varies according to the level of FVII, but it is essential to prevent intraoperative excessive bleeding. Methods: In this report, we described the orthognatic surgery experience in a mandibular prognathism patient with congenital FVII deficiency, in which recombinant activated factor VII (rFVIIa) was used to manage the bleeding. Rsults: We could get a successful result without any complication and there was minimal intraoperative bleeding. Conclusion: The orthognathic surgery could therefore be safely performed in patients with congenital factor VII deficiency using rFVIIa.

Hemophilia A is a sex-linked recessive coagulation disorder associated with diverse mutations of the factor VIII gene and a variety of phenotypes. The type of mutation involved dictates the activity of factor VIII, and in turn the severity of bleeding episodes and development of alloantibodies against factor VIII (inhibitors). Missense mutations are the most common genetic risk factors for hemophilia A, especially mild to moderate cases, but carry the lowest risk for inhibitor development. On the other hand, intron 22 inversion is the most common mutation associated with severe hemophilia A and is associated with high risk of inhibitor formation. Large deletions and nonsense mutations are also associated with high risk of inhibitor development. Additional mutations associated with hemophilia A include frameshift and splice site mutations. It is therefore valuable to assess the mutational backgrounds of hemophilia A patients in order to to interpret their symptoms and manage their health problems.
