  • This study was carried out to investigate the effect of fibrinogen genotype and other characteristics on the plasma fibrinogen levels. Many studies have conformed that high plasma fibrinogen levels are associated with the increased risk of ischaemic heart disease, stroke and arterial disease. And fibrinogen levels are related with age, obesity, cholesterol and alcohol consumption, genotypes. For this study the blood samples were collected from 93 healthy Koreans (66 males and 27 females). The blood samples were individually analyzed by smoking status, cholesterol levels, genotype, age, and gender. The plasma fibrinogen was assayed by clotting method (modified Clauss assay) and cholesterol was assayed by cholesterol oxidase method. Subjects were classified by current smokers, ex-smokers (<6 month), or nonsmokers. The $\beta$-fibrinogen genotype was detected by PCR of relevant region and digestion with HaeIII, with the H$_1$H$_1$ allele allowing cleavage by this restriction enzyme and H$_2$H$_2$ allele being refractory. In conclusion, the study shows that the factor of the increasement in the fibrinogen level was closely related with the cholesterol level, smoking status and genotype (H$_1$H$_2$); but there was no significant difference by gender, Especially, among the people over 50 years of age, fibrinogen level was higher with the increasement of cholesterol level (<200 mg/dl), current smoker, and genotype H$_1$H$_2$.

  • Many prospective studies have confirmed the predictive value of plasma fibrinogen levels for vascular diseases, including ischemic heart disease. Several polymorphisms of the $\beta$fibrinogen gene have been investigated in relation to plasma fibrinogen levels. The blood samples for DNA were collected from 109 healthy Koreans who have no relationship by blood (67 males and 42 females) in due consideration of some other factors such as gender, age, and smoking status. Four polymorphisms of the $\beta$fibrinogen gene that consist of HaeIII, AluI, MaII and BcII restriction fragment length polymorphisms (RFLPs) were investigated to examine the associations between RFLPs and plasma fibrinogen levels. In conclusion, the significant associations between HaeIII, AluI, MnII RFLPs(H$_1$H$_2$, M$_1$M$_2$, $A_1$A$_2$) and the concentration of plasma fibrinogen were shown by the smokers as well as by the old people more than 50, whereas the association between BcII and plasma fibrinogen were shown no connection with the status of age and smoking. The concentration of plasma fibrinogen was significantly shown higher by the old people ($\geqq$50) by the younger people ($\leqq$49) in male and also higher by the smokers than by the nonsmokers.

  • Plasma fibrinogen is risk factor of vascular disease including stroke, ischemic heart disease, atherosclerosis and thrombosis. Many studies have confirmed that high plasma fibrinogen levels are related with age, obesity, cholesterol, alcohol consumption, and genotype. This study was carried out to investigate the effect of fibrinogen genotype and other characteristics on the plasma fibrinogen levels in the elderly Koreans. For this study the blood samples were collected from 178 healthy elderly Koreans (102 males and 76 females, $55{\sim}80$ year olds). The blood samples were analyzed by smoking status, cholesterol levels, genotype, age, exercise, drinking, and gender. The plasma fibrinogen was assayed by clotting method, cholesterol being assayed by cholesterol oxidase method. The $\beta$-fibrinogen genotype was detected by PCR of relevant region and digestion with Alu I. The alleres with the restriction site and the non cleavable alleres were designated $A_1$ and $A_2$. In conclusion, genotype $A_1A_2$ and exercise are increased and associated with plasma fibrinogen levels. But, there were no significant differences by smoking, gender, age, drinking and cholesterol.

  • The aim of this study was to evaluate oriental medicine pattern identification in patients with stroke on the basis of plasma fibrinogen levels and platelet counts. 555 patients diagnosed with stroke between November 2006 and February 2010 were divided in several ways according to the plasma fibrinogen levels and platelet counts on admission. And comparative analysis of the distribution ratio of oriental medicine pattern identification was done between the groups. The mean value of the plasma fibrinogen levels of whole population was 449.18 mg/dL, and it was higher than normal range. The mean value of the platelet counts of whole population was 244.29 /mL, and it was lower but in normal range. Oriental medicine pattern identifications were not characteristic between groups divided according to the serum levels of fibrinogen and platelet counts. In this study, there was not significant correlation between Oriental medicine pattern identifications and the thrombotic factor like plasma fibrinogen levels and platelet counts. This study could be the steppingstone for the next study to develope the objective indicator for the Oriental medicine pattern identifications.

  • Purpose: The aim of the present study was to assess the association between the pre-operative plasma fibrinogen level and the adjacent organ involvement in advanced gastric cancer. Materials and Methods: A total of 923 pre-operative plasma samples were obtained from 923 patients diagnosed clinically as having advanced gastric cancer, and fibrinogen levels were measured by immunoassay. Associations between fibrinogen levels and clinicopathologic findings (depth of tumor, adjacent organ involvement, and lymph node metastasis), along with survival were examined by univariate and multivariate analyses. Results: Tumor size, tumor depth, and the presence of lymph node metastasis were found to be positively correlated with the preoperative plasma fibrinogen levels (P<0.001). Fifty (5.4%) patients had adjacent organ involvement. Lymphatic invasion (P<0.001), tumor size (P<0.001), clinical T (depth of invasion) stage (P<0.001), and clinical nodal stage (P=0.018) were found to be associated with adjacent organ involvement. Univariate and multivariate regression analyses showed that a preoperatively elevated plasma fibrinogen level was associated with adjacent organ involvement (P<0.001, 0.028), and Kaplan-Meier analysis showed that it was associated with poorer survival (P<0.001). Conclusions: Plasma fibrinogen was found to be a clinically useful marker of adjacent organ involvement and overall survival. When a high fibrinogen level is encountered, preoperatively, adjacent organ involvement should be suspected in clinically advanced gastric cancer.

  • The purpose of this study was to investigate the effects of garlic diet on blood coagulation in cholesterol-fed rats. 36 male rats were divided into six groups and fed experimental diet for three weeks. Two-levels (2% and 4%) of fresh and boiled garlic were supplemented to the stock diet with 2% cholesterol and 0.25% bile salt for the experimental diet. After the rats fed with experimental diets during 3 weeks, the whole blood coagulation time, the content of plasma fibrinogen, the fibrinolytic activity and the prothrombin time were measured. The results are summarized as follows; 1. Garlic diet have no influence on body weight and food consumption in rats. 2. In the case of cholesterol-fed group, the whole blood coagulation time was decreased 24.3% compared with the normal group(A). But garlic diet group(C) was similar to the normal group(A) and groupD-F was increased 4.9-11.5%. 3. The content of plasma fibrinogen of cholesterol-fed group was higher 114.5% than that of normal gropu(A). In the garlic diets(C-F) the contents of plasma fibrinogen were increased 33.1-63.8%. 4. The fibrinolytic activity of cholesterol diet was decreased 16.2% compared with the normal group(A) but was increased 10.9-44.5% compared to the garlic diets(C-F). 5. The prothrombin time of cholesterol-fed group was decreased 8.9% compared with normal group(A) but was increased 8.0-46.3% in garlic diets(C-F). As mentioned above, the garlic diets increased whole blood coagulation time, prothrombin time and fibrinolytic activity and decreased the content of fibrinogen. For that reason it is thought that the garlic diets have a anticoagulation effect regulating the fibrinogen synthesis in liver.

  • Fibrinogen alpha chain (FGA), a subunit of fibrinogen, might be a potential player for type 2 diabetes mellitus (T2DM), since the plasma levels of fibrinogen is known to be related to the incidence of T2DM. To elucidate the potential role of FGA in T2DM, we investigated whether FGA genetic variations are relevant in T2DM in the Korean population. Seven FGA single nucleotide polymorphisms (SNPs) were genotyped in Ansung and Ansan cohorts (474 T2DM subjects and 470 normal controls) in Korea. The association between SNPs and T2DM was determined by logistic regression analysis. Genetic relevance of SNPs to T2DM-related phenotypes was investigated by multiple linear regression analysis. Statistical analysis revealed that among seven FGA SNPs, significant associations with T2DM were observed in FGA rs2070011 (p=0.013-0.034, OR=0.72${\sim}$0.79), rs6050 (p=0.026${\sim}$0.048, OR=1.24${\sim}$1.37), and rs2070022 (p=0.016${\sim}$0.039, OR=0.70${\sim}$0.72). Two SNPs, rs2070011 and rs6050, also showed significant association with T2DM-related phenotypes such as triglyceride (p=0.005${\sim}$0.011 for rs2070011 and p=0.003${\sim}$0.008 for rs6050), total cholesterol (p=0.01 for rs2070011 and p=0.024 for rs6050) and fasting glucose (p=0.035${\sim}$0.036 for rs2070011 and p=0.048 for rs6050) in 470 normal controls. Our association study implies that FGA might be an important genetic factor in T2DM pathogenesis in the Korean population by affecting plasma lipid and glucose levels.

  • Even now, the hemorrhagic syndrome after cardiac surgery with the aid or a pump oxygenator constitutes a significant problem. The purpose of this study is to postulate the possible causes of the bleeding after open hear surgery [OHS]. Fifteen consecutive OHS patients with various heart diseases were selected and platelet count, plasma fibrinogen, serum calcium level were observed pre-, intra- and post- operatively until 21 th postoperative day [POD]. The platelet count was significantly decreased with initiation of extracorporeal circulation [ECC] and continued to decrease slowly until cessation of ECC. Within 10 minutes after ECC the platelet count stared to increase. But it was significantly less than preoperative count until 5th POD. The peak count was found on 14th POD and the platelet count was gradually decreased. Plasma fibrinogen also decreased significantly during operation, but it recovered up to preoperative amount within 5 hours after termination of ECC. Thereafter it rapidly increased until 3rd POD when it reached its peak. From 3rd POD it showed slow downward slope until 21st POD, but it remained in significantly higher level than preoperative amount. Serum calcium levels showed minimum fluctuations during the whole course of study. Conclusively, the decrease in platelet count and fibrinogen amount may play a considerable role for the postoperative hemorrhage. But numerous other effects of ECC must be accounted for.

  • In order to investigate the effect of Qingbaozhuyutang(淸胞逐瘀湯), Bee Veenom on 'Blood Stasis Pattern', here We regard Thrombosis and Elevated Blood viscosity as Blood Stasis Pattern. rats were injected Endotoxin into the caudal vein to make experimental thrombosis model(control group), and at sample group, rats were orally administrated solid extract of Qingbaozhuyutang(淸胞逐瘀湯) 0.5g/200g or were injected Apitoxin 1mg/Kg into the abdominal region(sample group), and then we observed platelet, fibrinogen, prothrombin time and FDP level. Another group were injected HA into the muscular rump to make experimental elevated blood viscosity instead of Endotoxin. Thereafter we measured whole blood viscosity and plasma viscosity. The results were summarized as follows. 1. Platelets were increased significantly in sample I compared with the control group. 2. Fibrinogen levels were increased significantly in sample I compared with the control group. 3. Prothrombin times were shortened significantly in sample II and sample III compared with the control group. 4. FDP levels were decreased significantly in sample II and sample III compared with the control group. 5. Whole blood viscosity and plasma viscosity were decreased significantly in all shear rates compared with the control group. According to the above results, it is considered that Qingbaozhuyutang(淸胞逐瘀湯) has significant effects on platelets, fibrinogens, prothrombin times, FDP levels, whole blood viscosity and plasma viscosities, therefore it seems to be applicable to disease related to 'Blood Stasis Pattern' through the thrombosis and elevated blood viscosity. But, Veenom has a little effect. the mechanism concerned for the effects is to be investigated in future.

  • The purpose of this research was to investigate the efficacy of Goiwhasan extract powder on the gastric injuries, antiulcer, gastrointestinal tract and blood hemostasis. Animals were used through this studies mice and rats. All animals were divided into 3 groups, contol group(no treatment), sample Ⅰ group(375mg/kg administration), sample Ⅱ group(750mg/kg administration). The gastric injuries and ulcer have been made by using pyloric ligation, indomethacin, HCI-ethanol, acetic acid and then The histological observation was followed. In the gastrointestinal tract, gastric juice secretion, gastric acidity, pepsin output, blood gastrin and secretin level, transport potentials in the small and large intestine were checked. And studies on blood hemostasis were performed on normal hemostatic activities and plasma prothrombin time, plasma recalcification time, plasma fibrinogen levels in the hypoprothrombinemic mice induced by warfarin. The results were as follows: 1. The antigastric ulcer effects on the pyloric ligation, indomethacin, HCl-ethanol, acetic acid induced gastric injuries were shown in Sample Ⅱ group(p<0.05). 2. Through the morphologic examination on the acetic acid induced ulcer, Sample Ⅰ group showed mild regeneration of epithelium and slight decrease of periulcer edema then that of Control group, while Sample Ⅱ group showed more retraction of round ulcer site, remarkable loss of swelling and edema then that of Control group, and revealing the regenerated epithelium in the surrounding ulcer site. Thus it was noted that both Sample groups have antigastriculcer effects on the experimentally induced gastric ulcer. 3. The inhibitory effects on gastric juice were noted in both Sample Ⅰ group(p<0.05) and Sample Ⅱ group(p<0.01). However, only Sample Ⅱ group showed the inhibitory effects on total acidity and pepsin output(p<0.05). 4. The significant inhibition of blood gastrin level showed at 30 min.(P<0.05) and 90 min.(P<0.05) after starting medication in only Sample Ⅱ group, but significance of blood secretin level in both groups was not recognized. 5. Any significant changes in barium sulfate transport in the small intestine of mice was not recognized in both groups, but the significantly inhibitory effect in large intestine was recognized in both Sample Ⅰ group(p<0.05) and Sample Ⅱ group(p<0.001). 6. In hemostatic effect on both normal mice and hypoprothrombinemic mice induced by warfarin, the significantly shortening effect on coagulation time was seen in only Sample Ⅱ group(p<0.01). 7. On plasma prothrombin time in hypoprothrombinemic rat induced by warfarin, Sample Ⅱ group have shortened the prothrombin time significantly(p<0.001). 8. On plasma reclcification time in hypoprothrombinemic rat induced by warfarin, the recalcification time have been shortened significantly in both Sample Ⅰ group(p<0.05) and Sample Ⅱ group(p<0.01). 9. On plasma fibrinogen levels in hypoprothrombinemic rat induced by warfarin, the fibrinogen contents in Sample Ⅱ have been decreased significantly(p<0.01). Overall the above results suggest that Goiwhasan has an therapeutic efficacy on antigastric ulcer and blood hemostasis. Further studies would be needed on the interaction of its herbal medicine and its mechanism in the future.
