The Computed Tomography is the most exact method to find out some diesase, soft tissue or musculoskeletal system. It is searching examination distinguishing normal structure and abnormal states in the spine and spinal canal. This is almost an absolute diagnostic method for spinal stenosis, and it has a special forte becasue it can distinguish the soft tissue around the spine. Thus we can distinguish metastatic cancer, herniated intervertebral disc, hypertrophy of the yellow ligament, and spine tumor very easily. Thirty-two cases of herniated intervertebral disc in lumbar spine were treated for 18 months from Jan. 1981 to Jun. 1982. Of thirty two cases, 18 cases were underwent CT scanning and 9 cases were underwent CT scanning and myelography. We obtained following results: 1. In the 18 cases taking a CT scan we found 6 cases of bulging annulus, 7 cases of herniated disc, one case each of facet syndrome, lateral recess syndrome, and three cases had normal finding. 2. In 9 cases taking CT scan, myelography and operation, 7 cases showed the same positive findings, but one case showed the positive CT scan and myelography, negative surgical exploration, and another case showed positive myelography, negative CT scan surgical exploration. 3. In 9 cases who took only a CT scan, there were 6 cases in which myelography was impossible or refused. Among these 6 cases 4 patients took operation and showed positive findings. 4. The diagnosis of herniated intervertebral disc by means of the CT scan has been made more accurately by the supplementary use of metrizamide and improvement of interpretation. a. When the patient refuses myelography. b. For discrimination of other diseases than herniated intervertebral disc. c. When the patient is allergic to iodine dyes used in myelography. As mention above, not only herniated intervertebral disc, but also many other diseases in spine can be diagnosed and we can decide that the herniated intervertebral disc surgery would by desirable with only the CT scan as nonivasive diagnostic test.

PURPOSE: This study was designed to analyze recent trends in research about caregivers of hospitalized children in Korea and to suggest future research directions in this area. METHODS: Eighty one studies selected from http://www.kan.or.kr, www.childnursing.or.kr, www.riss4u.net, and www.ndsl.kr published from 1995 to 2011 were used. The analysis framework of concepts was derived from client domain (Kim, 2000) and knowledge type (Kim et al., 2004). RESULTS: In terms of research design, nonexperimental studies (82.7%) were the most frequent, followed by experimental studies (14.8%) and qualitative studies (2.5%). Mothers were the most frequent caregivers, and hospitalization was the most frequent health problem of the children. In terms of categories of the concepts, 35 (39.3%) studies included essentialistic concepts like coping and adaptation, 15 (16.9%) studies included problematic concepts like anxiety and uncertainty, and 39 (43.8%) studies included health-care experiential concepts like educational needs and nursing needs. In term of knowledge types, there were 35 (39.3%) studies of the explanatory knowledge type, 44 (49.5%) descriptive ones, and 10 (11.2%) prescriptive ones. CONCLUSION: The results indicate that further research is necessary on problematic concepts and prescriptive knowledge types for child health nursing practice which will lead to expanding nursing knowledge.

The purpose of this epidemiological study is data for incidence of external genitalia anomaly in Korean male infants. 148 cases with external genitalia anomaly were found of total 1920 live male infants (including 132 low birth weights), except 48 still births, born in the hospital of Ewha Woman's University. The following results were obtained. 1. Total incidence of congenital anomaly was 7.5%. Undescended testes (4.5%), hydrocele (2.8%), hypospadia (0.2%) and bifid scrotum (0.1%) were found in order in frequency. 2. Imperfect descent of the testis was found in 88 infants. There were about 32.5% in infant under 2,500gm and about 2.5% in infant over 2,500gm. In 47 boys (30 low birth weights or 64% of the total) the imperfect descent was bilateral, and in 41 (29 low birth weights or 29% of the total) it was unilateral. Of the 41 unilateral cases, 22 were right sided. 54% of the total had been palpable at the external inguinal ring, 37% at the top of the scrotum and 10% had been not palpable. There were no significant differences either between distribution of birth order and incidence of undescended testes. But, their incidence was higher below 19 year-old group and above 35 year-old group in maternal age. Between March and May more boys were born with undescended testis, while their occurrence was considerably lower in November. 3. 90% of hydrocele was found in full term and right side had six times greater than left side. 4. Hypospadia was found in 4 cases of 1920 live male births. The associated anomalies were undescended testes in two cases and imperforate anus in one case. In the 2 cases, it was found at penoscrotal junction and 2 cases were glandular and penile type.

Paranasal sinus CT is known as the most effective imaging modality in the evaluation of inflammatory sinonasal diseases and can depict the distribution, causative lesions obstructing main drainge route, and associated findings. Recently, functional endoscopic sinus surgery has been widely used for the evaluation and treatment. Before operation, PNS CT has been routinely used to evaluate the paranasal sinuses and mucociliary drainage route. The authors analyzed the PNS CT findings of 3156 cases in 1578 patients with chronic sinusitis symptoms. Sinonasal inflammatory diseases were categorized into 5 patterns according to the obstruction sites. They were 1) infundibular (10%, 316/3156), 2) ostimeatal unit (41%, 1294/3156), 3) sphenoethmoidal recess (12%, 379/3156), 4) sinonasal polyposis (30%, 946/3156) , and 5) unclassifiable (6%, 190/3156) patterns. The main causes for infundibular obstruction in order of frequency were inflammatory mucosa, enlarged ethmoidal bulla and Haller's cell. With respect to the middle meatus obstruction, is main causes in the order of frequency were polypoid lesion, inflammatory mucosa and medially deviated uncinate process. In particular, sinonasal polyposis showed one or more of the characteristic associated findings of infundibular enlargement, air-fluid level, ethmoidal sinus was bulging and bony deossification or sclerosis as well as sinonasal polypoid change. In conclusion, the inflammatory sinonasal diseases were classified into five patterns, and the causative lesions or anatomic variations were efficiently detected by the PNS CT. Furthermore, it could provide a guidance for proper management of the sinusitis including functional endoscopic sinus surgery.

Primitive neuroectodermal tumors (PNET) of the ovary are rare tumors with an exclusive or almost exclusive malignant neuroectodermal composition, and are generally regarded as a monodermal expression of an ovarian teratoma. The tumors are basically identical with the lesions of the same name occuring typically in the central nervous system of children. These tumors consist chiefly of undifferentiated small cells resembling neuroblasts. There are also mature, well- differentiated neuroectodermal cells, such as astrocytes and ependymal cells. We report a case of ovarian PNET with glial and neuroblastic differentiation and focal teratomatous foci of non-neural tissue in a 17-year-old female.

This experiment was aimed to investigate the contractile responses of the fermoral artery to the electrical stimulation and the inhibitory effects of verapamil and papaverine on the electrical stimulation of the fermoral artery in the control (n=46) and the diabetic rabbits(n=40). Diabetic rabbits were made by and administration of alloxan (100 mg/kg) intravenously and sacrified 8 weeks later. Femoral arterial rings 3 mm in length were taken and mounted on the force-displacement transducer for the measurements of isometric tension. All experiments were done in the aerated (95% O2 with 5% CO2)biological chamber filled with Kreb's solution and the initial tension of 1.5g was applied to the rings. After 1 hour of equilibrium of the rings, the contractile responses of the electrical stimulation on the femoral arterial rings were taken without vasoactive drugs and then, under verapamil and papaverine solution. And we compared the morphologic findings of the vessels in the two groups in relation to the functional changes by transmission electron miroscopy. The results are as follows: 1. The contractile responses in the presence of verapamil or papaverine solutions to the electrical stimulation were lowed significantly in the fermoral arterial rings of the diabetic rabbits compared with that of the control rabbits (verapamil; 10M~10M: p<0.01, papaverine; 10M & 10M: p<0.01). 2. Transmission electron microphotographs showed many morphological differences of the femoral arteries between the control and the diabetic rabbits. These were irregularities of the internal elastic lamina and the hypertrophy of the cytoplasms of the smooth muscle cells. And also, there were many vacuoles in the cytoplasm of the endothelial cells, lateral to the internal elastic laminaes, and between the smooth muscle cells in the diabetic rabbit femoral artery. By this study, we found that the contractile responses of the femoral arterial rings to the electrical stimulation were decreased in the diabetic rabbits, and the vasodiatory effects of verapamil and papaverine on the electrically stimulated femoral arterial rings were also lowered in the diabetic rabbits compared with the control rabbits. These changes of the vasular responses of the diabetic vessel may be associated with morphological changes manifested by transmission electron microscopy or any other functional derangement of the vessels.

PURPOSE: The purpose of this study was to identify the factors influencing practices of health behavior for cancer prevention in university students. METHODS: Data were collected by questionnaires from 332 university students in J city. To analyze the data, descriptive statistics, t-tests, ANOVA, Scheffes test, and stepwise multiple regression analysis were performed with SPSS/WIN 21.0. RESULTS: The mean score of practices of health behavior for cancer prevention was 3.18+/-.41. Significant factors that affect practices of health behavior for cancer prevention in university students were self-efficacy, perceived benefits, health status, activity related affect, exercise, family's economic status, and the fear of cancer. These variables explained 31.7% of practices of health behavior for cancer prevention. CONCLUSION: The results of this study indicate that the level of practices of health behavior is not sufficient for cancer prevention among university students. Therefore it is necessary to develop a tailored education program to improve the practices of health behavior for cancer prevention in university students. It is also suggested that the education be focused on self-efficacy, perceived benefits and activity related affect.

Renal angiography has applications in the diagnosis of renal tumor and renovascular hypertension, and provides important anatomical information that can influence the surgical management. Recently the approach to the vascular system for diagnosis by means of Seldinger technique hag been expended to include a variety of therapeutic manner. So, embolization of renal carcinoma is being used with increasing frequency. Radiologic findings associated with presenting symptoms and signs were analysed in 51 cases of renal angiography, during the period of October 1978 to October 1982. The following results were obtained. 1. Male to female ratio was approximately 1:1 and peak incidence was in the sixth decade. 2. The main symptoms and signs of patients were hematuria, flank pain, hypertension and palpable mass, in order of frequency. 3. In 7 hypertensive patients with delayed visualization on the excretory urogram. angiography shows 2 cases of renal artery stenosis, one case of Takayasu's disease and absence of abnormal vasculature in 4 cases. 4. It is suggested most valuable technique for correct diagnosis of renal vascular disease. some of other congenital anomalies, and renal vascular mapping for renal surgery.
