In an attempt to investigate the specific antigenic substance of Fasciola hepatica, Ouchterlony tests and immunoelectrophoretic analyses were carried out. Crude Fasciola antigen was prepared and fractionated by Sephadex G-200 column to Antigen I, II and III according to protein content. Crude antigens of Paragonimus westermani, Clonorchis sinensis and Paramphistomum sp. were also prepared for control and absorption study. Antiserum was prepared by injecting 0.5 ml of crude Fasciola antigen with same amount of complete Freund's adjuvant in rabbits, 10 times at an interval of l week. The results obtained in this study were as follows: Crude Fasciola antigen reacted with antiserum with 9 precipitin bands by Ouchterlony test and with 11 bands by immunoelectrophoresis. Cross reaction was observed between Paragonimus, Clonorchis and Paramphistomum antigens and anti-Fasciola rabbit serum respectively. By Ouchterlony test, 3-4 cross reacting bands were found. Anti-Fasciola sera which were absorbed with respective Paragonimus, Clonorchis and Paramphistomum antigens, reacted with Fasciola crude antigen. Ouchterlony test gave 5-6 precipitin bands. Further reaction between Fasciola antigen and antiserum absorbed with the above 3 antigens concomitantly gave 5 precipitin bands by Ouchterlony test and 7 bands by immunoelectrophoretic analyses. Fractionated Fasciola antigens (Antigens I, II and III) reacted with anti-Fasciola rabbit serum in immunoelectrophoresis. Antigen I, II and III gave 2, 3 and 5 precipitin bands respectively. Anti-Fasciola rabbit serum which was absorbed with 3 trematodes antigens gave, by immunoelectrophoresis, 1 band with Antigen I, 2 bands with Antigen II and III of Fasciola hepatica. From the above results, it is concluded that Fasciola hepatica possessed the specific antigenic substance not cross-reacted with other trematodes.

Serological studies on toxoplasmosis were conducted with rabbits sera that were immunized with RH strain or infected with Beverley strain of Toxoplasma gondii. Complement fixation tests, agar-gel double diffusion tests and agar-gel immunoelectrophoresis were performed. Toxoplasma crude antigen was prepared from the organisms in mice peritoneal fluids, which were infected with RH strain of Toxoplasma gondii. The organisms were suspended in saline volume originally exudated and counted in hemocytometer for purity of the organisms over 99 per cent. These suspended organisms were prepared by sonication, and the solution was centrifuged for 30 min. at 10,000 rpm in 4C. These supernatant fluids were used as crude antigen. On the other hand, purified antigens were fractionated on Sephadex G-200 gel filtration. A Sephadex G-200 column, 80 by 4 cm, equilibrated with Tris-HCl-(0.1 M)-NaCl (1.0 M) buffer, pH 8.0 was used. The eluate fractions were collected in 3 ml per hour and the absorbance at 280 nm was measured with a Beckman Du-2 spectrophotometer. Each tube is pooled into 6 fractions by protein density graph. For immunization of rabbits, crude antigen of RH strain was emulsified with an equal amount of incomplete Freund's adjuvant and l ml of mixture was injected subcutaneously into them once a week for 5 successive weeks. Antisera were obtained at an interval of a week, beginning the first week after the last immunization, while several rabbits were infected with Beverley strain of Toxoplasma gondii by inoculating about 200 cysts and antisera were obtained from them serially at a week interval. The results were as follows: The sera from the rabbits immunized with the RH strain or infected with Beverley strain of Toxoplasma gondii againist the crude antigen showed the first positive reactions in 2 or 3 weeks after the administration or immunization in complement fixation tests. Maximum titers appeared in 4 or 5 weeks after immunization with RH strain and in 7 or 9 weeks after infection with Beverley strain respectively. Complement fixation tests showed the positive reactions in the rabbits sera immunized with RH strain against the purified antigens II, III, IV, V and VI: moreover, antigen IV fraction showed the highest titer. On the other hand in the rabbits sera infected with Beverley strain against the purifed antigens II, III and IV fractions showed the positive reaction; especially, antigen fraction IV showed the highest titer. In immuno-diffusion tests, the sera from the rabbits immunized with RH strain and infected with Beverley strain, against the crude antigen appeared the precipitin bands 2 weeks after the immunization or infection. And the former showed the 2 or 5 precipitin bands after 5-8 weeks and the latter showed the l or 2 precipitin bands after 6 weeks. The sera from the rabbits immunized with RH strain against the purified antigens II, III, IV,V and VI showed the precipitin bands, and the sera from the rabbits infected with Beverley strain against the purified antigens II, III and IV showed the precipitin bands in the immuno-diffusion tests. Especially antigen IV was the strongest reaction against the sera from RH strain and Beverley strain. In agar-gel immunoelectrophoresis, the immunized sera against the crude antigen showed 8 arcs. But the infected sera against the crude antigen showed 4 or 5 arcs. The immunized sera against the fractionated antigens II, III, IV, V, VI showed arcs, but against the fractionated antigen IV showed 6 arcs and in the antigens II, III, V, VI showed l or 2 arcs only. On the other hand, the infected sera against the fractionated antigens IV showed 4 arcs, II and III showed the l arcs, which was the most weak of all.

Fatigue is regarded as a universal and unavoidable side effects of chemotherapy. Most of patients in chemotherapy prefer resting and reducing their level of activity, but reduced physical activity can actually decrease physical strength and functional status to produce secondary fatigue. The purpose of this study was to determine the effects of rhythmic walking exercise on physical strength, fatigue, and functional status of breast cancer patients in adjutant chemotherapy. A matched control group pretest-pottiest design was used. Seventeen subjects of the experimental group were taught the rhythmic walking exercise(Winningham etal, 1990) on their first visiting day and encouraged to practice it at home throughout that treatment cycle(four weeks). Participants kept an everyday exercise diary that included pulse rates, exercise time and subjective data. The rhythmic walking exercise consists of approximately 30-minute walking, everyday if possible for 4 weeks. Outcomes were measured by each instrument :1) physical strength by the treadmill test estimated the walking ability. The subject is instructed to walk as long as possible to the level of their tolerance ;2)functional status by the Inventory of Functional Status-Cancer(Tollman et al, 1991) ; and 3)fatigue was measured by the Piper Fatigue Scale in both groups at five different times-before beginning chemotherapy(pretest) and one time per week for 4 weeks. Data were analyzed with mean, standard deviation, X2-test, t-test, repeated measure MANOVA using SPSSWIN program. Results were obtained as follows :1)The physical strength of the experimental group was significantly higher than that of the control group following the rhythmic walking exercise(t=3.92, p<.001). 2)The fatigue scores of the experimental group measured at the end of each week were significantly lower than those of the control group following the rhythmic walking exercise (1st week ; F=6.51, p<.016, after 1st week ; 863, p<.0001, after 2nd week ; F=46.754, p<.0001, after 3rd week ; F=60. 183, p<.0001, after 4th week). 3)The functional status of the experimental group was significantly higher than that of the control group following the rhythmic walking exercise (t=13.20, p<.0001). The results suggest that the appropriate rhythmic walking exercise for the breast cancer patients in adjutant chemotherapy can improve physical strength and functional status, and ultimately decrease the secondary fatigue.

In an attempt to investigate the antigen-antibody relations and the value of immunodiagnosis for several helminths, Ouchterlony tests and immunoelectrophoreses were carried out. Taenia saginata, Cysticercus sp. of cestodes, Clonorchis sinensis, Fasciola hepatica and Paramphistomum sp. of trematodes,and Ascaris suum of nematodes were used as antigens. On the other hand, antisera were obtained by injecting 0.5 ml each of the above antigens and the same amount of complete Freund's adjuvant into rabbits ten times at an interval of one week. The result obtained in this study are as follows: A larger number of precipitin arcs were demonstrated in homologous antigen-antibody reactions than in heterologous antigen-antibody reactions both in Ouchterlony tests and immunoelectrophoreses. Gross reactions were observed between the different species of the same class, but no cross reactions were noticed when the classes were different with one or two exceptions, such as between T. saginata, F. hepatica and A. suum. In A. suum, the difference between the male and female was more distinct in Ouchterlony test and immunoelectrophoresis than in the examination of organs such as genital organ and coeliac fluid. Immunoelectrophoresis revealed specific arcs and higher sensitive reaction than Ouchterlony test, and was considered to be a more valuable method for identifing species and immunological diagnosis.

In an attempt to investigate the sensitivity of immunodiagnosis in cats experimentally infected with Paragonimus westermani, agar-gel precipitin reaction were studied. Metacercariae of P. westermani were administered to cats in various doses(2-100 metacercariae per cat) and antisera were obtained at an interval of a week. Precipitin bands appeared in homologous antigen-antibody in experimental paragonimiasis between 3 and 5 weeks after infection in all the cats. Almost all the cases in which a large number of worms were detected, showed strong reactions as revealed by deeply stained bands. Precipitin reactions did not necessarily parallel with the number of worms detected. This may be attributable to the individual difference of a cat's conditions. Very weak precipitin reactions were noticed between Clonorchis antigen and Paragonimus antisera of cats, but no reactions were noticed between Paragonimus antigen and Clonorchis antisera of cats or rabbits.

Indirect fluorescent antibody tests were performed with sera of paragonimiasis patients and skin test positive sera against Paragonimus antigen. Paragonimus antigen was prepared from lyophilized adult worms of P. westermani by defatting with ethyl-ether before extracting with barbital buffered saline. Preparation of Paragonimus antigen for the indirect fluorescent antibody test was based upon Sato's method used for sero-diagnosis of anisakiasis, with Sephadex G-25 instead of Sepharose 4B. The results were as follows: The indirect fluorescent antibody titers of paragonimiasis patient's sera ranged from 1:64 to 1:512, whereas the control sera showed titers of less than 1:16. As controls, Clonorchis patient's sera and parasite-free healthy human sera were used. In indirect fluorescent antibody tests, the skin test positive human sera against Paragonimus antigen showed a positive rate of 41.5 per cent in the case of titers more than 1:40. On the other hand, complement fixation tests on the same sera showed a positive rate of 32.5 per cent in the case of titers more than 1:20.

The author examined expression of tumor-related antigens, such as p53 tumor supressor protein, c-myc, TGF-alpha, and TGF-beta proteins in 75 cases of surgically resected epithelial ovarian tumors. Peroxidase immunohistochemistry was used to determine the frequency of expression, the relationship among expression of these antigens and histopathological spectrums, and clinical stage, and their potential prognostic significance. The results are summarized as follows. A positive correlation was found between expression of p53(P=0.02), c-myc(P=0.03), and TGF-alpha(P=0.001) and histological degrees of malignancy(benign, borderline, or malignant) in epithelial ovarian tumors. A significant correlation was found between expression of p53 and histological degrees of malignancy in serous ovarian tumors(P=0.003) and mucinous tumors (P=0.049). A significant correlation was also found between expression of c-myc and the histological grade of serous carcinomas(P=0.02). A correlation between expression of these antigenic proteins and clinical stage of epithelial ovarian tumors was not demonstrated. Expression of p53 and c-myc was closely correlated with expression of TGF-alpha irrespective of the histological degrees of malignancy and type of epithelial ovarian tumors(0.4 < or = K < or = 0.7). The results of this study support the ideas that expression of c-myc and TGF-alpha might be a useful prognostic indicator in human ovarian carcinomas, and expression of p53 could be another indicator of prognosis, as the expression of p53 is characteristic in that the expression is mostly seen in invasive ovarian carcinomas.

BACKGROUND: Cosmetics are one of the common causes of contact dermatitis and many new cosmetic products are being introduced rapidly into our market. OBJECTIVE: Our purpose was to investigate the as is patch test result by several factors including age, cosmetic product and atopic diseases, and to compare as is patch result with those of standard and cosmetic patch tests. METHODS: The records of 240 patients were reviewed who had been patch tested with their own cosmetics and toiletries with a clinical impression of cosmetic contact dermatitis at the patch clinic of Kangnam St. Mary's Hospital in the period of 1991-1995. RESULTS: Of the 95 patients who were tested with European standard series 54 (56.8%) showed a positive reaction and nickel sulfate was the most common allergen. Eighteen (38.3%) of the 47 patients tested with a cosmetic series revealed a positive reaction and imidazolidinyl urea and dodecyl gallate were the most common allergens. In as is patch test, 99 (41.3%) of the 240 patients showed a positive reaction to 248 (7.3%) of the 3403 cosmetics. Common cosmetic products showing positive reactions were skin care products (26.2%), face make-ups (19.8%), and hair preparations (16.9%). There was no statistically significant difference in the positive reaction rate between atopy and non-atopy patients. The positive correlation rate of as is test with standard and cosmetic series was relatively low. CONCLUSION: Commercial standard patch test series including cosmetic series are not enough to detect causative allergen in cosmetic contact dermatitis. As is patch test should be encouraged to detect new allergens, because many cosmetic ingredients are developed and introduced in market.

PURPOSE: This study was to examine the effect of postpartum exercise on mental health. Mental health comprises a 9 symptom dimension of Somatization, Obsessive-Compulsive, Interpersonal Sensitivity, Depression, Anxiety, Hostility, Phobic anxiety, Paranoid Ideation, and Psychoticism. METHOD: A non-equivalent pre-test, post-test control group study was conducted. Fifty-two puerperal women who were admitted to a postpartum ward of a mother-baby clinic in Pusan were recruited; 26 women were assigned to the experimental group and 26 women to the control group. Postpartum exercise was applied to the experimental group from postpartum day 3 for a period of 8 weeks while no exercise program was applied to the control group. Mental health with SCL-90-R was measured before and after exercise. Data was analyzed using mean, x2-test, t-test, and ANOVA by SPSS 10.0. RESULT: The mental health status in the exercise group did not show a statistically significant decrease when compared to that of the control group. CONCLUSION: There is no effect of postpartum exercise on women's mental health during the first 8 weeks of the postpartum period. Further studies are needed for randomized clinical trials with a larger sample size.
