In order investigate the effect of Boyanghwanotang (BT) on thrombosis, Sprague-Dawley rats injected endotoxin into the caudal vein were oral administrated solid extract of BT-182. 4mg/200g (Sample A) and 364.8mg/200g (Sample B), and then observed Platelet, fibrinogen, prothrombin time and FDP. Another group injected hydrocortisone acetate into the muscular rump were adopted to observe the effect of BT on elevated blood Viscosity, administrated Sample A and Sample B, thereafter measured body weight, body temperature, whole blood viscosity, plasma viscosity, hematocrit, RBC, WBC, hemoglobin, glucose, albumin, total protein, triglyceride, cholesterol and prothrombin time. 1. Platelet was increased significantly in Sample B compared with the control group. 2. Fibrinogen of the trial groups compared with the control group was increased, and revealed a significance in Sample B. 3. Prothrombin time was decreased significantly in the trial groups compared with the control group. 4. FDP was decreased in the trial groups compared with the control group. 5. Body weight was increased significantly in Sample B after 7 days, body temperature revealed a significance in the trial groups after 5 days. 6. Whole blood viscosity and plasma viscosity of lower shear rates, both were highly decreased in the trial groupn than the control group. 7. The increase of WBC and decrease of hematocrit, RBC and hemoglobin was showed in the trial groups, and Sample B revealed a significance on the increase of WBC and decrease of RBC. 8. The increase of prothrombin time and decrease of glucose, albumin, total protein, triglyceride and cholesterol was showed in the trial group, and Sample B revealed a Significance on the increase of prothrombin time and decrease of albumin, total protein and triglyceride. 9. As compare with Sample A and Sample B, generally Sample B was highly Significant. According to the above results, it was considered that Boyanghwanotang may be the curative effects for thrombosis and elevated blood viscosity.
Hemorheology plays an important role in atherosclerosis. Hemorheologic properties of blood include whole blood viscosity, plasma viscosity, hemaocrit, RBC deformability and aggregation, and fibrinogen concentration in plasma. Blood flow is determine by three parameters (pressure, lumen diameter, and whole blood viscosity), whole blood viscosity is one of the key physiological variables. However, the significance of whole blood viscosity has not yet not been fully appreciated. Whole blood viscosity has a unique property, non-Newtonian shear-thinning characteristics, which is primarily due to the presence of RBCs. Hence, RBC deformability and aggregation directly affect the magnitude of blood viscosity, and any factors or diseases affecting RBC characteristics influence blood viscosity. Therefore, on can see that whole blood viscosity is the causal mechanism by which traditional risk factors such as hypertension, hyperlipidemia, smoking, exercise, obesity, age, and gender are related to atherogenesis. In this regard, we included whole blood viscosity in the three key determinants of injurious pulsatile flow that results in mechanical injury and protective adaptation in the arterial system. Because whole blood viscosity is a potential predictor of cardiovascular diseases, it should be measured in routine cardiovascular profiles. Incorporating whole blood viscosity measurements into a standard clinical protocol could improve our ability to identify patients at risk for cardiovascular disease and its complications.
This experiment was carried out to establish the grade of adhesion formation and changes of blood following artificial injuries such as abrasion, incision and electrocautery on colon and uterine horns in rats. 36 rats (abrasion-, incision-, electrocautery-treated groups) had laparotomy and abdominal injuries, twelve rats( control group) had only laparotomy, Ten days fellowing abdominal injuries, the score of adhesion formation and changes of blood were noted 1. Electrocautery-treated group was significant evident in adhesion formation in colon(p<0.01) and electrocautery and incision-treated groups were more evident than abrasion and control group in uterine horns(p<0.01) 2. Changes of erythrocytes number and PCV were tended to decrease during 5 days after operation, but recover normal level 10 days after operation. 3. Changes of leucocytes number were showed to significantly increase in electrocautery and incision-treated groups 5 days after operation. 4. The electrocautery-treated group was showed to significantly decrease in plasma protein and increase in plasma fibrinogen concentration.
120 heads of korean native calves were examined of serum protein by using cellulose acetate electrophoresis. During 20 days since the calves were purchased, serum protein, fibrinogen values and plasma : fibrinogen ratio were examined in the calves with respiratory and diarrheal disease. The result obtained in this investigation were as follows : 1. Among the 120 heads of calves that were purchased from market, 14 heads(22%) of calves were occurred respiratory disease, and 12 heads(20%) of calves are occurred diarrhea. Occurrence of respiratory disease was 14.5(4~20) days in average and diarrhea was 9.6(2-15) days after they had been purchased. 2. Serum protein fraction were analyzed by cellulose acetate electrophoresis. ${\beta}-globulin$, A/G ratio and ${\beta}_2-globulin$ values were decreased in the calves with respiratory disease. Especially, ${\beta}_2-globulin$ were significantly decreased. In calves with diarrhea, there was no change in ${\beta}-globulin$ values. ${\beta}_2-globulin$ values were higher than that of the normal and respiratory diseased calves. 3. ${\alpha}-globulin$ values were increased in both of calves with diarrhea and respiratory disease. This tendency was due to increase ${\alpha}_2-globulin$ values. 4. The $\gamma$-globulin value of calves with diarrhea was the lowest among the 3 groups. 5. The total protein values of normal calves were $7.0{\pm}1.1g/dl$ and that of respiratory and diarrheal diseased calves were $6.9{\pm}0.9g/dl$ and $6.6{\pm}0.8g/dl$, respectively. Total protein value of calves with diarrhea was lower than that of normal and respiratory diseased calves. Globulin value of calves with diarrhea was the lowest among them. The low value of total protein in diarrheal diseased calves was due to decrease globulin values. 6. The fibrinogen values of calves with respiratory disease ($643{\pm}189mg/dl$) were significantly higher than that of normal calves($533{\pm}135mg/dl$) and calves with diarrhea($572{\pm}188mg/dl$). The plasma : fib. ratio of respiratory diseased calves was $12.0{\pm}4.9$, normal calves was $13.8{\pm}3.5$ and diarrheal diseased calves was $12.8{\pm}4.6$. The ratio of the calves with respiratory disease was significantly decreased.
Anion-substituted poly(vinyl alcohol) (PVA) membranes, carboxymethylated PVA (C-PVA), and sulfonated PVA (S-PVA) were prepared and the effects of these substitutions on the plasma protein adsorption were studied by one- and two-dimensional gel electrophoresis and immunoblotting. When Cuprophane was used as a negative control, the amount of total proteins bound to samples decreased in the order Cuprophane > PVA > C-PVA > S-PVA, which we attribute to the effects of the surface characteristics of the samples, such as their surface tensions and electrostatic properties, on the adsorption of proteins to the surfaces of the materials. The results revealed that albumin was the most abundant protein in all the samples. The proportion of adsorbed fibrinogen to S-PVA exceeded those of PVA and C-PVA, whereas S-PVA exhibited the lowest IgG adsorption affinity among the samples we studied.
For the effective control of Syphilis, many investigators have developed a more rapid, simple and economical screening serological test which is adequately sensitive and specific. To fulfill the requirements of a more rapid serologic test for syphlis, a substitute for the conventional serum specimen was needed since considerable time and labor are involved in the processing of blood to serum. Burdon suggested the use of plasma in the serologic tests for syphilis as a substitute for serum. He noticed that plasma was more sensitive than serum in the Kline and Kahn tests, and attributed this to the presence of more antibody-like substance, "reagin" in plasma than in serum. However, to make plasma sufficiently sensitive, it was necessary to inactivate plasma by heating at a temperature of $56^{\circ}C$ for about 30 minutes. Heating of plasma resulted in the precipitation of fibrinogen which made centrifugation necessary to obtain dear plasma. Since the chief disadvantage to the use of unheated plasma(or serum) was a reduction in sensitivity of results-which probably was due to a labile factor such as complement-Portnoy et al began to consider rapid chemical methods of inactivation of plasma(or serum). They experienced that choline chloirde was shown to be anticomplementary which suggested its use as an inactivating agent for unheated plasma(or serum). In 1959 Portnoy et al reported the Rapid Plasma Reagin(RPR) Test for syphilis which is a more rapid, economical and simple. But still this test has many disadvantages as a rapid performing, field and office procedure, because it requires the usual laboratory equipments such as centrifuge, rotating machine, microscope etc. To substitute these disadvantages of the RPR test, in 1962, Portnoy et al developed the Rapid Plasma Reagin(RPR) card test for syphilis, which has the following advantages: a) Simplicity and rapidity of performance, b) Requires no laboratory equipments, c) Stable antigen suspension, d) Adequate sensitivity and specificity. This RPR card test can be used as a rapidly performing and screening test in field investigation, outpatient clinics, small laboratories and hospitals doing limited syphilis serology, and predonor in blood bank. Private clinic which has limited laboratory equipment and technic for syphilis serology can also use this RPR card test as a tool in the rapid diagnosis of syphilis. It was thought that this RPR card test is a useful tool in Korea for private physician and mass survey for syphilis diagnosis. But Portnoy patented the reagents needed for the performing the RPR card test. Therefore authors developed newly the reagents and according to Portnoy's method evaluated the newly developed. RPR card test compared with the VDRL, Kolmer CF, and RPCF tests. The RPR card and VDRL tests were performed plasma and serum from the total 1,132 cases. Among these 1,131 cases, 521 were syphilis suspected laboratory specimens, and 611 were syphilis unsuspected healthy young men. After screening with these two tests, the RPR card and VDRL tests, reactive specimens to the above one or both tests were retested by the Kolmer CF and RPCF tests.
