It would seem logical that a left to right shunt may be localized to that chamber in which an increase in oxygen content beyond the normal variation is first seen, while this is generally true, there are certain limitations to such direct diagnostic interpretation. The interpretation of an observed difference in oxygen content is influenced by the result of extremely poor mixing or of a change in respiratory, circulatory or metabolic steady states. This is one of the major challenges to proper interpretation. The purpose of this study was to analyze the blood oxygen content in various chambers of the right side of the heart in patients without shunt and to study the difference in oxygen content between the various chambers. The right heart catheterization was performed in 19 cardiac patients without shunt in Cardiac Laboratory in Hospital. 1. The blood oxygen content was 12.36+/-2.23 volume per cent (mean+/-standard error) in superior vena vava, 12.59+/-2.23 volume per cent in inferior vena cava, 12.59+/-2.23 volume per cent in mid-right atrium, 12.92+/-1.90 volume per cent in mid-right ventricle and 12.26+/-2.13 volume per cent in main pulmonary artery. 2. The mean difference of oxygen content was 0.16 volume per cent between superior vena cava and right atrium, 0.08 volume per cent between right atrium and right ventricle, and 0.06 volume per cent between right ventricle and main pulmonary artery.

The distribution of fibronectin and laminin in early chick embryos has been studied by immunohistochemical method. Fibronectin was detected not only at the basement membranes of neural tube, dorsal aortae and somites but also at the entire mesenchyme area. But laminin only appeared at the basement membranes. During the development of chick embryo, the distribution pattern of these glycoproteins was not changed but showed strong intensity of staining. The dorsal aorta of a 2-day-old chick embryo had several layer of fibronectin-producing cells, but was devoid of laminin. Laminin expression commenced faintly after Day 3. In the brain capillary wall, fibronectin was distributed but laminin was not at Day 10. In the cardiac jelly, fibronectin was detected as thin dotted strands but laminin was not expressed at Day 2. Along the endocardium, fibronectin was detected but laminin was not found. After Day 3, fibronectin was found as increased in endocardium, myocardium and cardiac jelly, whereas laminin expression commenced. Cushion mesenchymal cell migration and development of myocardial trabeculae were inhibited by antifibronectin injected in the cardiac jelly but not anti-laminin. Conclusively, this study suggests that fibronectin and laminin are glycoproteins in the extracellular matrix but there is a difference between their distributions. Cushion mesenchymal cell migration from endocardium and development of trabeculae in chick embryonic heart are inhibited by anti-fibronectin. This result suggests that fibronectin is a `stepping stone` for the embryonic migrating cells and triggers cell migration. But laminin may not serve as a matrix for cell migration.

The onprovement of civil registration reguires continuous study rather than periodic efforts. More and better statistics, however, are urgently required to formulate development programs and planning, Data obtainable from the civil registration are usually marred by errors of omission which are difficult to correct. This study aimed at finding out the problems occurring when a set of crude birth registration data in a rural area is used. Data Sources of this study are : 1) For birth registration : government birth registration records obtained from myun office and other government offices. 2) for the actual number of births : birth and child records from the Kang Wha Community Health Project. The study area is Sunwon Myun and Naega Myun in Kang Wha Gun, Gyunggido. The reference period for the accumulated data is one full year : Jan. 1st 1975 - Dec. 31st 1975. Major findings are as follows : If the number of registered birth is compared with the actual number of births which occurred in the target area, the former os far greater than the latter. The general assumption usually is , that the actual number of exceeds the registered number of birth in Korea. The observation from this specific study in this specific target area, shows the opposite trend. The number of births which actually occurred during the year of 1975 in the study area namely 256. The difference comes mainly from the fact that many cases of births from other areas were registered in the target area. In other words birth is not registered where it occurred but where the permanent residence address is. Among 550 births registered in the target area 66% did not occur in the target area. Only one third of all registered births were registered within the legal period for birth registration which is 2 weeks. 34% of the registered births actually occurred in 1974, but were registered in 1975. In 55% of the cases a difference was observed between the actual data of birth and the registered data of birth. From the 256 births which occurred in the target area, only 153 births (59%) were registered at the myun office and the remaining 130 births (41%) were not resistered there in the year of study. 6% of the 550 cases listed as registered have no separate registration sheets. Nevertheless, they definitely have been registered in the birth list at the myun office. 3% of the 550 cases are not recorded in this list but have a separate registration sheet at the myun offices. In conclusion, birth registration data have many errors and problems. Their usefulness as a source for vital and other statistics should be reconsidered. A series of sound methological studies will be necessary to establish their actual usefulness. A continuous and permanent compulsory system of birth recording is needed.

Lymphomatoid papulosis, first described by Macaulay in 1558 is a chronic disease characterized by the recurrent self-healing papulonecrotic or nodular skin lision, showing histological features of malignant lymphoma. The clinical course is variable, with rogression to disseminated malignant lymphoma in up to 10-20% of patients. Ki-1 appears to the a representative marker for large cells ir lymphomatoid papulosis and these cells can be detected in l-1 lymphorna, Hodgkins diseasen other disorders with aetivated T cells. However, positive Ki-1 staining is useful for supporting a diagnosis of lymphomatoid papulosis, under the appropriate clinical and histopathologic findings. We report a case of positive lymphomatoid papulosis which is characterized by the typical findings of clinical, histojpathological and immunohistochemica sizdies.

PURPOSE: This study identifies the relation among the essentials of fundamental nursing skills performance (EFNSP), work capability and stress from work experienced by new clinical nurses. METHOD: This is a cross-sectional descriptive study with a self-reported questionnaire. The subjects were 224 new clinical nurses employed by general hospitals having more than 400 beds. The data, collected from February 10 to March 7, 2014, were analyzed using descriptive statistics, t-tests, ANCOVA, Pearson's correlation analysis and hierarchical linear regression. RESULTS: The highest frequency of EFNSP of new clinical nurses was vital sign measurement (4.74, +/-.89) and the lowest frequency of performance was Basic CPR & defibrillator application (1.81, +/-.94). There were significant positive correlations between frequency and confidence of EFNSP (r=.64, p<.001), frequency and work capability (r=.34, p<.001), and confidence of EFNSP and work capability (r=.48, p<.001), but negative correlation stress from work and work capability (r=-.17, p=.009). General characteristics, stress from work, frequency and confidence in EFNSP and stress from work explain 25.1% of work capability. CONCLUSION: This result suggests the importance of EFNSP education in nursing schools and availability of opportunities to practice EFNSP during the post-graduation waiting period until assignment to a hospital.

PURPOSE: This study was performed to provide data for improvement in clinical practice education through analyzing the status of clinical practice education in maternity nursing in four year course nursing schools in Korea. METHOD: Analyzed subjects were 43 schools out of 53 four year course nursing schools in Korea. RESULT: Credits in theory and clinical practice are on the decline. The relationship between goals and areas of clinical practice was not sufficient. The department was not efficient in meeting the demands between theory and practice. The number of students in a group according to clinical areas were thoughtfully assigned, and clinical practice was performed based on real situations. Instructors for clinical practice used practice lecturers, part-time lecturers, preceptors, and assistant instructors including faculty. Methods of practice education and evaluation were varied. CONCLUSION: A suitable philosophy and goals of clinical practice education maternity nursing should be established at this point in time. Furthermore, a study should be performed to analyze the relationship between goals and contents of clinical practice for maternity nursing. In addition, a standardized tool should be developed to evaluate clinical practice.

Congenital dislocation of the hip has been known as one of the most common congenital anomalies in the orthopedic field since the time of Hippocrates (460-357 B.C.). The occurence of C.D.H. in twin babies is extremely rare thus few if any papers have been reported. During the period of January 1971 through June 1976 the authors have treated a total of 49 cases as inpatients. Two of these were twin babies. In both cases the hip was surgically reduced and followed by open reduction and femoral derotation osteotomy. Clinically and radiologically the results were good during the duration of follow-up seven months after operations.

Fractures of the carpal navicular is a serious injury, particulary in a manual worker, because non union and the resultant disability may limit the usefulness of the extremity. There is almost unanimous agreement that fresh fractures of the carpal navicular should be treated by immobilization in a plaster cast and how immobilization should be maintained. As a result of this study we have arrived at several conclusion regarding to the conservative treatment of fresh navicular fracture.

So called pseudosarcoma of the esophagus is an extremely rare polypoid malignant tumor and a number of cases, totaling 19 cases have been reported in world literatures until 1985. The presenting case is an unique one of pseudosarcoma of the esophagus and we illustrated all microscopic features with mapping, immunoperoxidase stain for cytokeratin and electron microscopic findings to clarify the histogenesis of spindle cells. It is postulated that the spindle cells of pseudosarcoma are transformed from squamous carcinoma cells based on (1) morphological similarity between squamous epithelial cells and spindle cells, (2) positive reaction of immunoperoxidase staining for cytokeratin in the adjacent normal esophageal mucosa, squamous cell carcinoma, spindle cells and giant cells and (3) presence of transformation zone.
