Experimental radiation nephritis was produced in 15 rabbits by X-irradiation. About $2,000{\gamma}$ (tissue doses) were given to both kidneys of a rabbit in 5 days. Other tissues and organs except both kidneys were protected with 2mm thickened lead plates. 5 weeks after the last irradiation, blood pictures, blood pressures, B.U.N., serum creatinine, Ca, Mg, Fe levels and serum erythropoietin activity of the irradiated rabbits were studied. After finishing above studies, rabbits were sacrificed and both kidneys were removed and examined histopathologically. Same laboratory and pathological studies were performed in 6 control rabbits. In this study, the author obtained following results. 1) Both kidneys of rabbitis with experimental raditation nephritis showed marked histopathological changes, i.e.: renal tubules showed diffuse cloudy swelling, impacted intraluminal hyaline casts and focal precipitations of lime salts on the tubular epithelium. Diffuse interstitial fatty necrosis and various degrees of fibrotic infiltrations on the interstitium were also seen in association with focal lymphocytic infiltrations. Hyaline degenerations were observed on the glomeruli and small vessels. 2) Experimental radiation nephritis rabbits showed marked lowering in R.B.C. counts, decreased hemoglobin levels, low hematocrit values and leucopenia in comparison with those of control rabbits. (P<0.01). (Table 1 & 2). 3) Mild proteinuria were observed in experimental radiation nephritis in rabbits. 4) The levels of B.U.N. and serum creatinine increased in experimental radiation nephritis. (P<0.01). (Table 1,3 & 4) 5) The levels of serum Ca and Mg Showed no statistical difference in comparison with those of control rabbits. (P>0.05) (Table 3 & 4). 6) No statistical correlations were observable between the levels of B.U.N. and Hb. values. (${\gamma}=-0.223$) No close correlations (${\gamma}=-0.328$) were noticed between the levels of B.U.N. and serum iron levels. 7) Erythropoietin activity (R.B.C. $^{59}Fe$ Incorporation) was measured by the modified Fried method. No change in its activity was noticed in radiation nephritis group comparing with that of the control group. (P>0.05). (Table 1,3 & 5). 8) Carotid artery blood pressures showed also no difference. (P>0.05). (Table 1 & 2).

Pneumoconiosis is a pathological change which is caused by coal dusts. It is a chronic disease that is not cured thoroughly but need treatment and nursing care through all lifetime of the patient. The family of the patient will be suffered from the physical and mental difficulties in the consequence of pneumoconiosis. The study is to find out the characteristics of the families with pneumoconiosis patients. The subjects of the study were 300 families with pneumoconiosis patients who were under medical treatment in Taeback, Donghae, Jeongsun Occupational Medical Center. The period of the study was from the 8th to the 31st of August, 1998. The data were collected by the structured questionnaires included the family intensity measurement which was translated by "Oh". The general properties of the subjects were calculated by frequency and percentage with SAS program. The followings are the summaries of the study. 1) The mean age of the pneumoconiosis patients was 62.3 years. The mean duration of diseases was 11 years and 7 months and the mean duration of hospital stay was 6 years and 4 months. 2) The mean age of the primary care giver was 55.7 years. The proportion of highschool education was 9.6% and it was quite low level compared to other primary care giver groups. 3) The average number of family members were 1.76 person(2.76 persons included patient). The economic status was somewhat high compared to other families with chronic patients. 4) The mean score of family intensity was 41.2(item mean=3.4). With the result, it is recommended to develop a program to improve the quality of family life. For example, there will be social support program for pneumoconiosis patients family sponsored by Social Insurance for Occupational Diseases.

Objectives : This experiment was designed to assess the single oral toxicity of Ethanol Extract Inulae Flos (IF) ethanol extracts. IF is one of the important herbs to remove phlegmy which is the viscous turbid pathological product that can accumulate in the body, causing a variety of diseases. Nevertheless, there has been a lack of research on the pharmacology toxicity of IF. Methods : In this study, IF was orally administered to 5 weeks ICR mice as an oral dose of 2,000 or 3,000 or 5,000 mg/kg. The condition of the mice was observed for 14 days and their weights were measured every two days. Results : None of the mice died for 14 days. The abnormal clinical symptoms and anatomical signs of toxicity were not found in any treatment groups. The gain of net body weight was observed. There was also no significant difference in the organ weight. The serum biochemistry and hematological analysis showed a decrease in BUN, red blood cells, white blood cells and platelets although within the normal ranges. Conclusions : These results suggest that the 50% lethal dose of IF is more than 5,000 mg/kg. This could be thought that IF is a safe drug without acute toxicity and side effects. However, IF showed some weight loss and change in blood test, so it will need to be careful when using it for high doses.

뇌의 허혈-재관류 손상에 있어서 혈소판 활성인자 (PAF, platelet activating factor)의 관련을 증명하기 위하여 흰쥐와 생쥐에서 양측 총경동맥을 10분간 결찰하고 그후 6시간동안 재관류시켜 허혈-재관류 손상을 야기시켰다. 생쥐에 PAF 길항제인 BN52021과 CV6209 (각각 1 mg/kg, i.p.)를 총경동맥결찰 10분전 또는 재관류 시작 1시간 후에 투여시 McGram stroke index는 심하게 억제되었다. 흰쥐와 생쥐에서 뇌허혈-재관류에 의한 뇌수분함량의 증가는 BN52021 또는 CV6209 전처치에 의하여 유의하게 억제되었다. BN52021 전처치는 허혈 후의 혈압변동을 개선시켰을 뿐만 아니라 뇌연막동맥의 확장지연에 대하여도 효과가 있었다. 이러한 실험결과로 보아 PAF가 뇌허혈-재관류 손상의 발생에 내인성 인자로서 중요한 역할을 하는 것으로 사료된다. 나아가 PAF 길항제가 뇌허혈후의 병리학적 후휴증의 개선 내지는 예방에 사용 될 수 있을 것으로 기대된다.

The goals of nursing education, and the bases for evaluating them depend on the goals of nursing practice. In order to prepare for the coming twenty first century and the meet changing societal demands and health needs, it is necessary to develop a new conceptual framework for future nursing education. While hospitals will still be in significant components of the health care system, will no longer be central focus or dominant influence. Health care services will be more usually delivered at community base. The nursing education required by that new approach must provide for reconsidered about a concept of caring as nursing curriculum. The changes in health care delivery that have occured, now being proposed, for nursing education undergoing its own changes. So the philosophy and objectives of education meed to reconsidering about the caring concept and general nursing. Nurse educators must prepare students to practic in condition of constant change. At the same time nurse educators must emphasize preparation about that. The practice of science of caring in nursing draws on a basic knowledge of the behavioral knowledge, biophysical processes, pathological processes, nursing skills and procedures and various treatment regimes and problem solving to help decision making in nursing situations. The concept of care is probably one of the least understood ideas used by professional and nonprofessional people, yet it is probably one of the most improtant concepts to be understood by nursing. Human caring and human relationships are closely interrelated. Humn caring remains an essential dimension of professional work and the science of caring as essental to the discipline of nursing. It is expected that the objectives of nursing education will be accomplished when the course and content of the curriculum are based on this conceptual framework. One recurrent education goal with some consistency is that of equipping the student with the necessary skills to live effectively and productivly in the world of tomorrow. In the new vision we are developing, professional education must also include exposure to liberal arts, encouragement of critical thinking, and a moral context for advanced professional education that is based upon a contextual health policy and caring science educational model.

Stomachs from 3,354 fattening pigs were examined at slaughter during the period from September 1980 to August 1981. Pigs of both sexes and $Landrace{\times}Hampshire$ crossbreds were included in the present studies, and they weighed about 60-120kg. Gross pathologic alterations of the stomach were classified as normal, epitnelial change, erosion, ulcer and scar formation. Representative tissue sections were taken from the stomach lesions at random and fixed in 10% buffered formalin. Cut sections were stained with hematoxylin and eosin, and examined histopathologically. The results obtained in the present studies were as follows. 1. In the seasonal prevalence of gastric ulceration, severe ulceration with erosion was shown during the Autumn and Winter, whereas mild ulceration was mainly shown during the Spring and Summer. 2. Of the 3,354 stomachs of the pigs, 20.8% were found to be normal. Of the rest, 40% had epithelial changes, followed by erosion (24.7%), ulcer (13.6%) and scar formation (0.9%), respectively. 3. In the prevalence of ulcers in the different regions of the stomach, the fundic region had the highest rate (61.6%) of ulceration, followed by cardiac (21.7%), esophageal (15.0%) and pyloric region (1.7%). 4. The principal gross changes were severe epithelial changes with keratotic proliferation in the esophageal region, and in the fundic region severe folding of the stomach wall was covered with bloody mucous exudates. 5. Main histopathological changes were inflammatory cell infiltrations in most cases, hemorrhages in acute ulcers and prominent proliferation of granulation tissues in chronic ulcers.

For the purpose of the basic educated-establishment on the diagnostic methods of "facial color and shape which reflect human's spiritual essence and personality", we study on the diagnostic value and application of the human face. The study's domain is divided the form and color of human face. And the form and color of human face is respectively observed the diagnostic value and contents. The form of human face reflect plenty the information of the mankind, and the observation of the face is applied to the "Physiognomie" refering to the external features of humans. Therefore the diagnosis on the form of human face is the primary factor in the grouping of five-element human, the discrimination of the Sasang constitution, and the classification of Hyunsang type. The color of human face reflect the physical information of internal organs and the pathological change of disease, therefore we examine the region, character and grade of disease by the inspection of complexion including the changes of color and luster of the facial skin. The inspection on the color is also the primary factor in the grouping of five-element human, the classification of Hyunsang and the differentiation of syndromes. The value of the inspection of complexion including the changes of color and form of the face is widely known. In the future, we think, we need to study more about the theory of the diagnostic value and application of the human face.

For the development of drugs for alzheimer,s disease, the study was done to review the oriental pathology, clinical data, recent trends for research and strategy for future study. The results were as follows: 1. The medical term Chi-dsi implying alzheimer,s disease was referred for the first time in a medical book, Hwatasheneubijeon written by Hwa-Ta and its differentiation and treatment were studied more in Ming or Ching dynasties. Chi-dai can be differentated as weak(虛) syndrome and Shi(實) syndrome. This can be caused by deficiencies of renal Yin, renal Yang, cardiac Yin and hepatic blood, while that by deficiencies of pathological fluid(痰飮) and clotted blood(瘀血). 2. Dementia can be roughly classified as alzheimer's disease and multi-infarct disease. Its causes were known to be cholinergic transmitter, C-peptide, amyloid-${\beta}$, apolipoprotein, APP(amyloid precursor protein), TGF, MMP-9 and free radical. 3. In Korea experimental studies were chiefly done for the elimataion of C-peptide, amyloid-${\beta}$, apolipoprotein, APP for alzheimer's disease, for the development of drug inhibiting degerative change following CVA and loss of memory and also administrative measure was done by support of government. 4. Drugs of dimentia developed so far were Chi-Dai dan, extracts from aloe, mushroom, green tea, Ganoderma and also folic acid, vitamin C, DHEA and silk amino acid were reported to be effective in dimenta. 5. Future strategic research had better be done on dementia-inducing factors such as acetylcholine, C-peptide, amyloid-${\beta}$, apolipoprotein, APP, TGF, MMP-9 and free radical, development of animal model for dimentia, clinical study, epidemiology, nursing and administrative studies and also consortium for dimentia research should be formed so that repeated investment be avoided.
