Congenital afibrinogenemia is a rare disorder characterized by a congenital lack of fibrinogen, a key component of the hemostatic system. Bleeding manifestations of congenital afibrinogenemia vary in severity from mild to catastrophic. This is a case report of splenic rupture occurred in an eight-year-old boy with congenital afibrinogenemia. Nonoperative treatment with cryoprecipitate and virally inactivated, purified fibrinogen concentrates successfully avoided splenectomy.

The purpose of this study was to determine the association between blood lipids, fibrinogen, fasting blood sugar, lifestyle-related factors and lipoprotein(a). This study was performed with 140 healthy adults (male:80, female:60) among the teachers in primary, middle, and high school in Seoul in November 1996. Lipoprotein(a) concentration was measured with an enzyme-linked-immunosorbents assay(ELISA), and the results showed that the distribution was highly skewed and the average concentrations of male and female were $16.94{\pm}12.70\;mg/dL\;and\;17.92{\pm}7.58\;mg/dL$, respectively. The percentage of subject with lipoprotein(a) concentrations higher than 30 mg/dL was 26.4%. Univariate analysis showed significant association between lipoprotein(a) and age, alcohol, meat, and NaCl consumption (p<0.05). In multivariate analysis, lipoprotein(a) correlated positively with age (p<0.05) and meat consumption (p<0.01). These data suggest that lifestyle-related factors may affect the lipoprotein(a) concentration regarded as a risk factor of atherosclerosis disease.

This experiment was carried out to investigate the high-frequency gluing characteristics of poly vinyl acetate emulsion adhesive(PVAc) on MDF edge-glued boards. The edge-glued boards were glued lengthwise with butt, scarf, or finger joint. The wastes of MDF boards were reused as board materials. The obtained results are summarized as follows; the bending strength of edge-glued MDF increased slightly with the HF heating time, but the economically desirable heating time was 6 minutes. The bending and tensile strength of edge-glued MDF were high with scarf, finger and butt joint, in order. The strength of finger jointed MDF showed 80% of scarf jointed MDF. The effects of location of finger joints on the bending strength of edge-glued MDF were larger than those of the numbers of finger joints. The bending strength of edge-glued MDF with one joint on the middle position showed 40% decrease in comparison with non-jointed MDF.

This study was performed to determine the effectiveness of poloxamer/sodium alginate mixture(PX/SA) barriers on prevention of post-operative peritoneal adhesion in dogs. Fifteen mongrel dogs were divided into three experimental groups: non-treated group, 2% Sodium Carboxymethylcellulose (SCMC) treated group and PX/SA treated group. In order to induce adhesions, the anti-mesenteric serosa of the ileum was exteriorized and then abraded in a standard manner by scraping with a scalpel blade to create homogeneous petechial hemorrhagic surface over a 1 ${\times}$ 1 cm area. Solution of SCMC was allowed to spread across the intraperitoneal organs through a catheter using a syringe. PX/SA was simply coated over the abraded tissues. On day before and day 1, 4, 7, and 14 after operation, venous blood specimens were collected for measurement of RBC, total WBC and fibrinogen. The adhesions were blindly assessed 3 weeks later by using a computerized tensiometer. The RBC, total WBC and fibrinogen values of three groups showed no statistical significances. The mean tensile strength(gram force, gf) of formed adhesions on day 21 after surgery was 173.05${\pm}$113.48 in the non-treated group, 111.42 ${\pm}$ 38.25 in the SCMC group, and 69.00 ${\pm}$ 45.07 in the PX/SA group. The tensile strength values for adhesion seperation in PX/SA group was lower than those in SCMC group(p < 0.05) and significantly lower than those in the non-treated group(p < 0.05). Our data suggested that PX/SA should be effective on reducing peritoneal adhesion formation in dogs compared with SCMC. PX/SA may be applicable to preventing post-operative intraperitoneal adhesion in dogs.

Background: The purpose of this study was to independently evaluate the beneficial effects of a high dose of transamine administrated prior to CPB on the postoperative hematologic aspect and bleeding. Materials and methods: This study included randomly selected groups of 40 adult patients undergoing OHS with CPB. All patients were divided into 2 groups: transamine group (T-group, n=20) and placebo group(P-group, n=20). The T-group received a high-dose of transamine(10 g) before and during CPB. The P-group received normal saline at the same times and served as a control group. Results: The results of comparative studies between the 2 groups in the same hematologic variables were summarized as follows. \circled1 During CPB, the fibrinogen concentrations and platelet counts were significantly lower in the P-group than in the T-group(p<0.01). \circled2 During CPB, production of D-dimer occurred in 18 patients(90%) in the P-group and did not occur in the T-group(0%) (p<0.0001). \circled3 At CPB-off, the % concentration of fibrinogen(70.2$\pm$3.9%) and the % platelet counts(72.4$\pm$4.5%) of the T-group were significantly higher than those(54.5$\pm$3.8%, 64.3$\pm$2.9%) of the P-group(p<0.01). \circled4 Postoperative values of PT(14.0$\pm$0.03 sec.) and aPTT (27.6$\pm$0.1 sec.) of the T-group were significantly lower than those(16.0$\pm$0.02sec., 30.1$\pm$0.1sec.) of the P-group(p<0.05). \circled5 Postoperative bleeding and requirement of whole blood and other blood products were significantly less in the T-group than in the P-group(p <0.05). \circled6 There were no significant hypercoagulability signs such as cerebral em bolism, myocardial infarction, pulmonary embolism, or any other neurological prob lems in either group. Conclusions: We concluded that a high dose of transamine administered prior to CPB prevents the activation of fibri nolytic system and has beneficial effects of reducing the postoperative bleeding t endency without apparent hypercoagulability signs.

Storage material of endosperm cells digested by various enzymes should be transported to the embryo. At this time, the cellulose of the endosperm cell wall is guessed to be hydrolyzed by the cellulase enabling to transfer the storage material from the endosperm cells to the embryo. Therefore, this study has been carried out to investigate the ultrastructure of endosperm and the localization of the cellase activity on Cannabis sativa L. during germination. Endosperm cells contain a large number of lipid bodies and protein bodies with globoids as the storage material. During gemination they are gradually degenerated, however, the former almost remain until the cells are completely digested. Electron-microscopical reaction products of cellulase on endosperm cells are present. The closer the embryo, the more amount of reaction products on the endosperm cell wall are appeared.

Metalloenzyme was purified from the fruiting bodies of Tricholoma sejunctum. MALDI-TOF and ICP/MS analyses revealed that the enzyme had a molecular weight of 18788.25 and includes $Zn^{2+}$ ion. The N-terminal amino acid sequence of the enzyme was Ala-Thr-Tyr-Lys-Ile-X-Ser-Ala-Thr-His-Gln-X-X-Leu-Val. The activity of the enzyme was inhibited by EDTA and 1,10-phenanthroline, indicating that the enzyme was a metalloprotease. No inhibition was found with E-64 and pepstatin. It has broad substrate specificity for synthetic peptides. The enzyme was stable up to $40^{\circ}C$. The activity of the enzyme was increased by $Zn^{2+}$ and $Co^{2+}$, while it was totally inhibited by $Hg^{2+}$. The enzyme hydrolyzes $A{\alpha}$ subunit of human fibrinogen but did not show any reactivity for $B{\beta}$ and ${\gamma}$ form of human fibrinogen.

From December of 1994 to April of 1995, we, SHUH Department of Pediatric Thoracic and Cardiovascular Surgery, studied effects of aprotinin. 95 patients were randomly divided into two groups : group I (n=47) with aprotinin and group ll (n=48) without aprotinin. Aprotinin was given as one shot injection to cardiopulmonary bypass perfusion solution with dose of 50,000 KIUikg. Laboratory data such as hemoglobin, hematocrit, BUH, creatinine, fibrinogen, electrolyte concentration, aPTT, PT, and AT R was checked preoperatively, 5 minutes after anesthesia, 5 minutes and 35 minutes after CPB circulation, and 5 minutes, 3 hours, and 24 hours after reperfusion. Also, chest-tube drainage, transfused amount of RBC, platelet concentrate, and fresh frozen plasma within first 24 hours postoperatively were checked and analyzed after transition nn body weight demension. Only RBC transfused postoperatively had statistical significance with P value of less than 0.001. Others had no difference statistical wise. Postoperative side effects of aprotinin was not detected weeks after the surgery and there was no reoperated patient due to postoperative bleeding.

The objective of this study was to identify and characterize fibrinolytic compound from Cornus officinalis. Cornus officinalis. Hot water extract was fractionated into hexane, chloroform, ethyl acetate, butanol, and water fractions. Assays for fibrinolytic activity indicated that only the ethyl acetate fraction had significant efficacy at 1.36 plasmin units/mL. Isolation of fibrinolytic compound was carried out on Amberlite IRA-400, Sephadex LH-20 and active charcoal column chromatography. HPLC analysis of the purified fibrinolytic compound showed retention time (RT) same as authentic malic acid. LC / MS / MS in negative mode showed the same peak at m/z 133, confirming that the purified compound was malic acid with a molecular weight 134 Da. The compound showed fibrinolytic activity of 0.69 plasmin units/mL, 14.62% of thrombin inhibitory activity, 6.42% of antioxidative activity, and 17.28% of α-glucosidase inhibitory activity. The purified compound hydrolyzed γ subunits of human fibrinogen. In conclusion, malic acid isolated from Cornus officinalis might have potential to be developed as ingredient for biofunctional foods to prevent cardiovascular diseases.
