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.

Possible seasonal differences in serum Insulin-Like Growth Factor-I (IGF-I) concentrations have not been studied in newborn infants. Recently we demonstrated sea- sonal differences in bone mineral content (BMC) in newborn infants: lower BMC was present in summer vs. winter-born infants (J Pediatr Gastroenterol Nutr 1992; 15: 285). In a second stduy, higher serum osteocalcin, an index of bone formation, and lower BMC were found in summer vs. winter (J Pediatr Gastroenterol Nutr 1994; 19: 2207). We speculated that increased serum osteocalcin in summer could be an adaptive response to decreased bone mass. Since growth factors such as IGFs are local regulators of bone formation, we hypothesized that in summer-born infants, serum IGF-I will be higher than in winter, associated with high bone formation activity. Fifty-nine healthy, term appropriate for gestational age (AGA) infants were studied prospectively in winter (Jan-Mar, 29) and in summer (July-Sept., 30). Thirty infants were male, and 29 infants were female. Gestational ages and birth weights were not different by season(in summer, mean+SD, 39.61.1 wk, 3,471360 g,' in winter, 39.31.4 wk, 3,402 392 g). Cord serum IGF-I was measured by radioimmunoassay, modified from Furlanetto et al (1977), after acidification and sep-pack extraction of serum, and osteocalcin concentrations were determined by a kit radio-immunoassay. Cord serum IGF-I concentrations were not different by season of birth(summer vs. winter, 20.11.83 vs. 16.5 1.75 ng/mL, p=0.2). No gender differences were found: 18.21.8 vs. 18.2+1.8 ng/ mL in males vs. females. Serum osteocalcin was higher in summer vs. winter-born infants (8.22.3 vs. 4.951.58 ng/mL, p=0.009). BMC was different by season (87.2+ 14.5 vs. 94.1+16.4 mg/cm, p=0.02). Cord serum IGF-I was not related to serum osteocalcin and BMC. We conclude that serum IGF-I concentrations are not different by season or gender, and are not related to bone formation activity and BMC. Thus, IGF -I concentrations in serum are not seasonally regulated, nor associated with an index of bone formation activity.

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.

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 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.

The purpose of this study was to identify the effects of phase 1 cardiac rehabilitation nursing care on cardiac rehabilitation knowledge, anxiety, and self-care behavior in patients with acture myocardial infarction. The study design was composed of a nonequivalent control group non-synchronized design and a non-equivalent control group post-test design. The subjects of the study consisted of thirty-four acute myocardial infarction patients hospitalized at a university hospital in Taegu between February 16, 1998 and May 12, 1998. the 34 research subjects were assigned to experimental( 17 patients ) and control( 17 patients ) groups. The phase 1 cardiac rehabilitation nursing care was composed of cardiac rehabilitation education taken from a rehabilitation manual and booklet, and participating in a progressive exercise program. After discharge, a phone interview was conducted in order to encourage the self-care behavior. The modified Knowledge Scale developed by Rahe et al.(1975) and translated into Korean by Hwang(1986), and the modified Self-Care Scale of exercise and diet based on Hickey et al.(1992), were used for data collection. Analysis of data was done by use of Chi-square test, t-test, Repeated measure ANOVA, Simple Main Effect, and Time contrast. The results of this study are as follows : 1. The first hypothesis, "The experimental group which received the phase 1 cardiac rehabilitation nursing care will have a higher level of knowledge than the control group", was supported(F=24.07, p=.000). 3. The third hypothesis, "The experimental group which received the phase 1 cardiac rehabilitation nursing care will have higher self-care behavior scores than the control group", was supported( t=-15.49, p=.000 ). From the above results, it can be concluded that phase 1 cardiac rehabilitation nursing care is an effective nursing intervention knowledge, reducing anxiety, and improving self-care behavior in patients with acute myocardial infarction.

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.
