  • 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.

  • Studies on modified complement fixation (MCF) test of antiblackleg bovine serum were made and the results obtained were summarized as followings. 1. The most satisfactory antigen for the MCF test among various materials studied was found to be the vegetative cells of Cl, chauvoei grown in cooked meat medium (CMM) containing 0.5mM l-(alpha) alanine and 0.1mM manganese. The antigen was prepared by inoculating the spores of Cl. chauvoei, heated at $70^{\circ}C$. for 30 minutes, into the CMM followed by incubation at $37^{\circ}C$. for 15 hours. 2. An active component contained in the factor serum of fresh normal rabbit serum was found to be C'4 fraction. It was also shown that, furthermore, DEAE cellulose sieved C'4 fraction of the factor serum enhanced antibody titer and the highest antibody titer was resulted by the addition of 0.03 ml, of the factor serum to each tube. 3. More than four fold increases of antibody titer, in antiblbckleg bovine serum-antigen system, was made with the MCF test than that with the direct complement fixation test. 4. The MCF antibody titer of cattle vaccinated against blackleg was 128 until seven month and 64 for five months thereafter.

  • This study was conducted to investigate the relationship of serum calcium and magnesium levels to depression and anxiety symptoms in 80 homemarker. Fasting blood samples were collected and serum calcium and magnesium concentrations were measured. At the same time, psychological conditions of subjects were estimated by questionnaire. As the result of psychological test, eighty homemarkers were divided into two groups according to psychologicaltest scores. The subjects in one group got high pssycholgoical test scores as high score group (HSG) and the others got low physchological test scores as low score group(LSG). Serum calcium and magnesium concentrations were significantly(p<0.05) lower in HSG than in HSG than in LSG. Many a subject who belonged to HSG appeared to have depression and anxiety symptoms. Drepression and anxiety scores of the subjects with calcium supplementation were significantly (p<0.05) lower than those without calcium supplementation . After calcium supplementation, depressiion and anxiety scores were significantly (p<0.05) decreased in HSG and serum calcium and magnesium concentrations in HSG were significantly increased to normal ranges . This results suggested that psychological conditions of homemarkers might be affected by serum calcium and magnesium levels.

  • The purpose of this study is to analyze the effects of exercise therapy on serum lipid levels and antioxidants of obese and normal college female students. The subject group composed of ten normal-weight students(below 30% body fat ratio) and ten obese students(above 30% body fat ratio). After a pilot test, the subjects were given an eight-weeks exercise program. Before and after the exercise program, the subjects were given test for serum lipid and antioxidants were analyzed. The SAS program was used in the data analysis. The statistical measurements employed here were T-test, Wilcoxon signed rank test, and Wilcoxon rank sum test. The results of this research are as follows. 1) The effects of exercise therapy on serum lipid levels : Before the exercise therapy, the levels of Total-cholesterol, Triglyceride and LDL-cholesterol of the obese group were highier than those of the normal-weight group. However, the HDL-cholesterol levels were highier in the normal-weight group than in the obese group, but these differences were not significant. With the exercise therapy, the levels of Total-cholesterol increased gradually. The HDL-cholesterol increased gradually, the LDL-cholesterol level decreased in both groups, However, the Triglyceride level decreased in the obese group and increased in normal group, but the difference was not significant. 2) The effects of the exercise therapy on serum antioxidants ; Before exercise therapy, the serum FR and GSSG levels of the obese group were significantly highier than those of the normal-weight group(p=0.00, p=0.04). The serum GSH level of the normal-weight group was highier than that of the obese group, and the serum MDA level of the obese group was highier than that of the normal-weight group. Again these differences were not significant. With exercise therapy, serum FR level was reduced and serum GSSG level significantly increased in both group(obese group p=0.01, normal-weight group p=0.01), The serum GSH level of the obese group significantly increased (p=0.01), and serum MDA level significantly increased in the obese group(p=0.01), but the difference in the normal-weight group was not significant. These results show that regular exercise therapy reduces serum FR levels and activation of antioxidant systems, and suppress oxidative stress. These effects were slightly highier in the obese group than in the normal-weight group. The regular exercise therapy decreased the serum Triglyceride levels more in the obese group than in the normal-weight group. However the improvement of the serum lipid profile may require a longer exercise period than eight weeks. The results show that the exercise therapy was overall more effective in the obese group than the normal-weight group.

  • A total of 710 bovine serum samples which are composed 532 bovine serum samples showed negative reaction and 178 bovine serum samples showed positive reaction with tube agglutination test (TAT) from North area of Gyeong-nam, Korea were tested using all the 3 assays which are Rose-Bengal test(RBT), tube agglutination test (TAT) and enzyme-linked immunosorbent assay (ELISA, two types) and analyzed for evaluation of specificity, sensitivity, reproducibility and predictive value. In the comparison of serum antibody titer agglutination test, RBT showed almost agreement with TAT. In the comparison of TAT and two types of ELISA method, they showed difference in specificity and sensitivity about 5%. But there is no significant difference in detecting sensitivity between two types of ELISA method and TAT. In serologic tests for bovine brucellosis, the new assay ELISA would be a good candidate for serologic survey for bovine brucellosis in Korea because it is efficient in detecting many test samples quickly. But the serum agglutination tests (RBT, TAT) are more economical and easy assay for detection. In the test of comparison of antibody titer between first day of finding and 10 days after finding by TAT, there was no change in 55% (76/139) of positive cattle.

  • Borna disease(BD) virus 특이항체검출에 대한 세 가지 혈청진단법(간접형광항체법, 세포효소면역반응법, 혈청중화시험)의 정확도를 비교하기 위해 BD virus를 실험적으로 감염시킨 273수의 토끼의 혈청으로 시험하였다. 혈청중 간접형광항체법에 의하여 판정된 123혈청들은 모두 세포효소면역반응법에 의해서 양성으로 판정되었으나 혈청중화시험법에 의해서는 단지 27혈청에서만 양성으로 판정되었다. 혈청중화시험법은 간접형광항체법과 세포효소면역반응법에 비하여 민감도가 훨씬 낮게 나타나 BD virus의 혈청학적 연구에는 간접형광항체법 및 세포효소면역반응법의 활용도가 높을 것으로 생각된다.

  • Endotoxins are part of the outer membrane of the cell wall of gram-negative bacteria and are continuously released during bacterial growth. Endotoxins typically induce severe sepsis and septic shock, which cause more than 50% of mortalities. Endotoxins are easily measured in the serum by the limulus amebocyte lysate (LAL) test. However, a nonspecific result is obtained, because the high concentration of serum proteins disturbs the enzyme reaction of the LAL test. In order to solve this problem, the LAL test was performed in this study after the centrifugation of the boiled serum samples to remove the impurities. As a result, among the various conditions examined, endotoxin measurement with the LAL test was the most accurate and repeatable after centrifugation of the boiled serum at $100^{\circ}C$. Moreover, the endotoxin was accurately and repeatedly measured from the prepared sera of mice that had been administered an intraperitoneal injection of purified lipopolysaccharides (LPS) or E. coli. Therefore, the application of centrifugation to remove impurities from boiled serum gives an accurate measurement of endotoxins in the sera of normal subjects or patients, and this will lead to the improved diagnosis and prevention of diseases caused by endotoxins. In addition, the centrifugation of boiled serum samples should be considered and included in the development of endotoxin test kits.

  • Purpose: This study examined the effects of foot-reflexology massage on body weight, lower extremity edema, and serum lipids in postpartum women. Method: This study was a nonequivalent control-group pretest-posttest design. Postpartum women were assigned to the experimental group (n=16) or a control group (n=15). Foot reflexology massage was applied 5 times a week, for a total of 2 weeks to the experimental group. The tool for measuring lower extremity edema was the girth of the thigh, and the calf. The measuring tool for serum lipids was total cholesterol and TG in blood serum by clinical process. Data was analyzed by $x^2$-test, t-test, and paired t-test, ANOVA using SPSS/Win PC 14.0. Results: There was a statistically significant decrease in levels of TG in blood serum in the experimental group compared to the control group. Conclusion: Foot reflexology massage is a useful nursing intervention that decreases serum lipids level in postpartum women. Therefore foot reflexology massage is recommended as a nursing intervention strategy for serum lipids reduction in postpartum women.
