Pulmonary paragonimiasis is one of the most important endemic parasitic disease in Korea. Although it is well known that Paragonimus westermani invades into the lung tissue eventually resulting respiratory failure, the pathogenesis of inducing lung lesions is not fully elucidated. It is still debatable on the nature of morphological component of 'cyst' which is known to be the most consistent change in lung paragonimiasis. For the purpose of clarification of morphological changes associated with pulmonary paragonimiasis, an experimental study was carried out by giving metacercariae of P. westermani to 10 dogs. These dogs were sacrificed 2 months and 6 months after infection respectively, and light microscopic and electron microscopic observations were made. Following conclusions were obtained. Paragonimus lung lesions could basically be classified into two categories, i.e., direct mechanical effects by the worms and eggs, and the changes secondary to the worm infection. The relative importance of these two appeared almost same. Adult worms of P. westermani reside inside the lumina of the dilated bronchi in great majority of the cases. Only exceptions were secondary abscess formation and subsequent scar where no epithelial lining was detected around the worms. In 6 months group almost all P. westermani worms were found inside the bronchial lumina. Obliterative endobronchiolitis was another prominent feature among changes that were not directly associated with worms or eggs. This finding was more prominent in the distal segments of the bronchial trees that harbor the Paragonimus worms. P. westermani eggs were found as isolated and aggregated fashions, provoking characteristic granulomatous inflammation. Some of the egg granulomas were seen in the areas apart from the locations where the worms were physically located. Ultrastructural observations of the cyst wall showed fair numbers of plasma cells and mast cells. Some of the cystlining epithelial cells showed increased deposit of glycogen granules, suggestive of early metabolic alteration of the respiratory epithelium.

This study was done to compare the breast-feeding primiparas' perceptions of their babies with bottle-feeding primiparas' at 2-3 days after delivery. The subjects of this study included 42 breast-feeding mothers and 56 bottle-feeding mothers. Data were collected by using the Neonatal Perception Inventory(NPI) devised by Broussard(1963) and added by Lee, Ja Hyung(1986) form December, 1996 to June, 1997. The results of this study are as follows : 1. Primiparas perceptions of their babies according to their general characteristics. 1) There was no significant difference in mothers' perceptions according to mothers' age and whether they have a job or not. 2) There was a difference in mothers' perceptions according to their educational level(P<0.1). 2. The comparisons of breast-feeding mothers' perceptions of their babies with bottle-feeding mothers'. 1) There was no significant difference in the two group's perceptions of other babies 2) There was no significant difference in the two group's perceptions of their own babies. (1) Breast-feeding mothers' general perceptions of their own babies were better than bottle-feeding mothers', but there was (2) Breast-feeding mothers' perceptions about the basic needs of their own babies were better than bottle-feeding mothers', and there was a significant difference between the two groups(P<0.05). (3) Breast-feeding mothers' perceptions about the sense and motor abilities of their own babies were better than bottle-feeding mothers', but there was no significant difference between the two groups. (4) Breast-feeding mother's perceptions about the necessary care of their own babies were lower than bottle-feeding mothers', but there was no significant difference between the two group. 3) There was no significant difference between the two groups' positive-negative perceptions of their babies (1) 69% of breast-feeding mothers and 69.9% of bottle-feeding mothers had positive perceptions about general conditions, but there was no significant difference between the two groups (2) 57.1% of breast-feeding mothers and 46.4% of bottle-feeding mothers had positive perceptions about the needs of babies, but there was no significant difference between the two groups. (3) 50% of breast-feeding mothers and 48.2% of bottle-feeding mothers had positive perceptions about the sense and motor abilities of babies, but there was no significant difference between the two groups. (4) 57.1% of breast-feeding mothers and 60.7% of bottle-feeding mothers had positive perceptions about the necessary care for babies, but there was no significant difference between the two groups. 3. 54.8% of breast-feeding mothers tried to feed their own babies on the 1st day after delivery. 83.3% of breast-feeding mothers chose the feeding method for themselves. Only 9.5% of breast-feeding mothers took recommendations for breast-feeding from nurses. 78.6% of breast-feeding mothers had no chance to learn about breast-feeding. 69% of breast-feeding mothers complained about the difficulties of breast-feeding. The most serious problems were : 'insufficient milk supply', 'lack of knowledge about feeding technique' and 'problems with nipples'.

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.

This study is a descriptive survey conducted for the purpose of providing basic data to develop the effective nursing in interventions for Coronary Heart Disease patients. It was focused the relations between the type A behavior pattern and Health Locus of Control of them datd were collected through face-to-face interview with 55 CHD patients who were hospitalized at one of the general hospitals in Taegu city from May 11 to July 27, 1977. The instruments used for this studyy were the Jenkiness Activity Scale(Jenkins, 1979) and Health Locus of Control Scale(Wallstone & Wallston, 1978). Analysis of data was done by using of Person Correlation Coefficient, t-test, ANOVA, stepwise multiple regression and Cronbach with the SAS program. The results were as follows; 1. Total type A behavior pattern score was 67.2(total 88), job involvement /hard-driving subscale 35.9(total 47), sped subscale 12.8(total 16) and impatient subscale 19.09(total 25). The highest score of the type A pattern was the speed subscale 3.75 when it was transferred as a full mark 4. 2. When the total score of Health Locus of Control Scale of CHD was made 5, internal health locus control was the highest with 3.9, powerful others health locus control 3.6 and chance health locus control 3.0. 3. Women were significantly higher than men on total type A behavior pattern(p=.0453), job involvement/hard-driving subscale(p=.0492) and impatient subscale(p=.0460) according to general characteristics. Angina pectoris patients showed significantly higher than myocardial Infarction patients in total type A behavior pattern score(p=.0266), involvement/hard-driving subscale(p=.0365) and impatient subscale(p=.0185). 4. It was not significantly different for the Health Locus of Control Scale according to general characteristics. 5. Correlations between subscales of type A behavior pattern and subscales of Health Locus of Control showed that there were significantly positive correlation between internal health locus control and job-involvement/ hard-driving subscale(p=.0500), and between powerful others health locus control and important subscale(p=.0204). 6. The variances that can explain the causes of type A behavior pattern were systolic blood pressure 9%, quantity of smoking per day 9.6%, dyastolic blood pressure 8.6%, internal health locus control 6.2%, which accounted for 34.3% of the total variances. The following suggestions are made on the basis above results ; 1) The instrument that measures type A behavior pattern of CHD patient need to be modified and developed as an instrument that is applicable with Korea environment and easy to understand for subjects. 2) Replication of the research is need with nation wide samples. 3) Follow-up study for correlation between subscale of the type A behavior pattern and subscale of Health Locus of Control is needed. 4) Intervention program for CHD patients to reduce type A behavior pattern is to be developed.

Although a family-centered approach to health care for developmentally disabled children has been advocated, existing systems of care have not adequately addressed the support needs of the family system and the essential role that parents play in the daily care of these children. The overall purpose of this research is to examine family system adaptation to the care of a developmentally disabled child using the Resiliency Model of Family Stress, Adjustment, and Adaptation Framework. Relationships among family system demands(stressors, strains, transitions, child's illness factors) and family system strengths and capabilities(resource of social support) were examined to determine their separate and combined contribution to explaining the variability inn family system outcomes(family system coping). The subject for this study was 46 families who have a child with developmental disabilities(mental retardation and/or autism) from three special educational programs in Seoul, Korea, Results from correlation and hierachial regression analysis revealed that perceived social support operated as a resiliency factor between family stress and coping. Child and family characteristics appeared to be important predictors of perceived social support and coping. In summary, there is evidence that the resource of social support as a family strength and capability was found to improve the family coping. These findings also must be viewed within the context that sample of families of children with disabilities was relatively small and eligible families from support group of special educational program.

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.

The purpose of this study was to identify the children's sleeping patterns, such as the sleeping hours and the nature of sleep disruptions following hospitalization and its accompanying factor. The data were collected from December, 1997 to March, 1998 using a questionnaire developed by researchers. The subjects were 76 children in a hospital. The results of this study were summarized as follows : 1. The average sleeping hours(sleep duration) at night were 10 hours and 10 minutes and 9 hours and 9 minutes before and after hospitalization respectively. There was a significant difference(P<0.01). 2. The mean bed time(sleep onset) was 10:22 pm and 10:28 pm before and after hospitalization respectively. There was no significant difference. 3. The mean hour of rising(sleep termination) was 7:54 am 7:08 am before and after hospitalization respectively. There was a significant difference(P<0.01). 4. The mean number of sleep disruption was 0.72 and 1.94 before and after hospitalization respectively. There was a significant difference(P<0.01). The sleep disruptions were influenced by crying of other children(53.9%), lights(28.9%) nursing procedures(18.4%), noise of TV(17.1%) and noise of visitors(15.8%).
