Although this vascular anomaly, angiomatosis retinae, was initially observed over 85 years ago, and although excellent clinical description of the lesion exist in the literature, treatments for the angiomatosis retinae is difficult and unless the condition is in its early stages, impossible but available symptomatic therapy. Two cases of the angiomatosis retinae, the first, 11 year old girl, von Hippel disease, early stage of vascular dilatation and angiomatous formation, and the second, 15 year old boy, von Hippel-Lindau disease, the final stage of glaucoma and destruction of the eye, are reported. Intravenous fluorescein angiography has been demonstrated, the retinal vascular malformations in von Hippel-Lindau disease are distributed focally and not diffusely, The retinal veins showing greater changes than the arteries are disclosed. This paper presents the fluorscein angiographic findings of von Hippel-Lindau disease and discusses the treatments and the pathologic findings of angiomatosis retinae with literatures related to von Hippel-Lindau disease.

BACKGROUND: Not rarely we can find young people with acute myocardial infarction(AMI), many studies revealed they have fewer risk factors and less severe coronary angiographic abnormalities than middle and old aged group. METHODS: We studied clinical characteristics and coronary angiographic findings of 5 young men with AMI treated at Masan Koryo General Hospital from June 1986 June 1992. RESULTS: The age ranged between 19 and 32 years(mean 25.4). They had no other risk factors except cigrarette smoking(4 out of 5). Their coronary angiograms revealed no significant lesion in each infarct related artery. After discharge, all patient remained asymptomatic. CONCLUSION: AMI in young man might be related with cigarette smoking, and coronary artery spasm and/or thrombosis may play a significant role in its pathogenesis.

In order to determine the enzyme activity, as expressed in Reitman-Frankel unit, of GOT isozyme present in whole homogenate, mitochondrial fraction and supernatant fraction were prepared from brain tissues of normal adult rabbit, by a differential centrifugal method. The effect of thiopental on the GOT isozyme activity in each fraction was determined and the following results were obtained. 1) The activity of GOT isozyme in whole homogenate of normal rabbit brain tissues was found to be 545+/-2.608 units/mg of wet weight whereas the corresponding figure for the supernatant GOT isozyme was 512+/-3.081 and the value for the mitochondrial GOT isozyme was found to be 34.9+/-1.224. 2) The supernatant GOT isozyme existing in a floating status within the cytoplasm accounted for 94 percent followed by 6.35 percent of mitochondrial GOT isozyme. 3) The activated-peak of mitochondrial GOT isozyme contained in the whole homogenate of adult rabbit brain tissues was found to be at #15 on the tube of elution in comparison to that of #73 for supernatant GOT isozyme, as analyzed by the DEAE-Cellulose column chromasography. 4) The supernant GOT isozyme from the thiopentaltreated brain was proportionaly distorted while mitochondrial GOT isozyme was not influenced. Fro example, treated with thiopental, the supernatant GOT isozyme was divided to be #63 & #73 on the tube in comparison to #15 for the mitochondrial GOT isozyme. 5) The activity of supernatant isozyme was proportionaly reduced as the concentration of thiopental. 6) Fifty percent inhibition dose(1se) of thiopental on the supernatant GOT isozyme was found to be 0.63mM. 7) The inhibitory effect of thiopental on the supernatant GOT isozyme was very high significantly by the statistics. 8) The mchanism by which thiopental inhibits the supernatant GOT isozyme in the adult rabbit brain was found to bh uncompetitive inhibition as its Michaelis-Menten constant Km=58.07mM demonstrated. In view of the above finding it is suggested that the thiopental inhibited selectively the activity of supernatant GOT isozyme of the adult rabbit brain tissues while it did not inhibitnificantly by the statistics. 8) The mechanism by which thiopental inhibits the supernatant GOT isozyme in the adult rabbit brain was found to bh uncompetitive inhibition as it Michaelis-Menten constant of Km=58.07 mM demonstrated. In view of the above findings it is suggested that the thiopental inhibited selectively the activity of supernatant GOT isozyme of the adult rabbit brain tissues while it did not inhibit that of mitochondrial GOT isozyme. The GOT isozyme of adult rabbit brain tissues was divided into thiopental-sensitive GOT isozyme(supernatant GOT isozyme) and thiopental insensitive GOT isozyme(mitochondrial GOT isozyme) Furthermore, it is suggested that the cellular function of the brain can be somewhat hindered, when thiopental is injected into the brain cell, while mitosis of the brain cell is not influenced.

The recent availability of recombinant human erythropoietin has opened new perspectives in the management of a variety of anemias. Clinical trials have been initiated in several countries using different approaches and methodology. We randomly assigned twelve premature infants(gestational age < 32 week) at high risk of requiring erythrocyte transfusion for anemia of prematurity with either subcutaneous recombinant human erythropoietin or a placebo. Treatment with rHuEPO was initiated at a dose of 100 units/kg day for 3 days a week. All patients were given supplemental oral iron therapy at a dose of 3 mg/kg per day, as tolerated and oral vitamin E at a dose of 25 units per day. Treated and control babies did not differ with respect to weight, hematocrit, overall mean reticulocyte count or rate of growth respectively. However, reticulocyte counts increased earlier in patients given rHuEPO. We conclude that rHuEPO administration is safe and feasible at the dose studied.

INTRODUCTION: Critical thinking involves identifying problem(s), assessing resources, and generating possible solutions and allows clinical nurses to decide which solution is the most reasonable under the given circumstances, taking into consideration the "what ifs" and how they will affect the end result. This research was conducted to further understanding and identification of subjective factors in critical thinking in clinical nurses. METHODS: The research design was a Q-Methodological Approach. Q-population was formulated from a non-structured questionnaire and interviews from 17 experienced clinical nurses. Thirty selected Q-statements were sorted by 30 experienced clinical nurses. RESULTS: Four factors for critical thinking were identified: (1) Deductive reasoning based on causal relation, (2) Construction of an effective model based on patients' responses, (3) Formulating categories based on priorities for effective interventions, and (4) Judging validity of the situational significance on clinical performances. CONCLUSION: Critical thinking is an attitude and reasoning process. From this study, the frame of reference for clinical nurses in formulating critical thinking within the context of clinical settings is identified and indicates the way nurses utilize thinking skills when they care for patients and areas that need further exploration as nurses and faculty develop education systems to advance clinical performance competency.

Tuberculosis of the puboischium is an uncommon entity. The two constant features in tubereulosis of the pubis are limping and abscess formation. This disesse should be differentiated from other diseases such as osteitis pubis, suppurative osteomyelitis, postpartum synphysiolysis, and adolescent osteochondritis. Kirker advocated that wide excision of the lesion for the treatment of this disease is the best method. However, Nicholson(1953) reported that the lesion has a good prognosis snd responds well to simple curettage. Since the first reports by Thilesen(1855) and by Heinnies(1888), there were paucity of reports. Also in Korea, there have been no report about this disease. The five patients who were treated at the Ksng-Nsm St. Marys Hospitsl between 1982 and 1987 were reported. The results were as follows ; 1. Four patients were boys and one was a female. 2. All cases had clinically abscess, tenderness at the lesion, and limp. 3. Lesions in four cases responded well to simple curettage and18 months of chemotherapy. However, in one case fusion of the symphysis using a plate was performed because of tuberculosis-induced instability of the sacroiliac joint. 4. In a child, destroyed symphysis pubis was well restituted after treatment. Through the cases it is concluded that simple curettage and anti-tuberculous chemotherapy are good treatment modality for tuberculosis of the puboischium.

For 16 years after the finding of HIV as an agent of AIDS in 1981, HIV therapeutic drugs of reverse transcriptase inhibitors (AZT, ddI, ddC, d4T) and protease inhibitors have been developed. Recent studies also were focused on a combination therapy by using HIV therapeutic drugs or natural compounds. Korean red ginseng (KRG) of natural compounds has been well known as a good reinforcement agent in Asia. The percentage of CD3+CD4+ T cell in nine HIV-infected patients without KRG treatment averaged 17.8% on baseline and decreased 15.8% after 6 months, whereas the percentage of the cell in fifteen HIV-infected patients with KRG treatment averaged 15.3% on baseline and increased up to 18.9% after the same period. The average percentage of CD3+CD8+ T cell of KRG-nontreated and KRG-treated HIV patients increased after 6 months 47.8% to 50.7% and 44.7% to 51.4%, respectively; and the average percentage of B and NK cell in the KRG-nontreated and KRG-treated HIV patients decreased 9.4% to 7.9% and 13.0% to 9.7%, 8.9% to 8.5% and 16.2% to 11.6%, respectively, KRG, therefore, didn't have any effects on the CD3+CD8+ T cell, B cell, and NK cell. However, it seems that KRG has a potential activity for stimulating the

BACKGROUND: Bag and mask devices are used frequently to provide patients with positive-pressure-assisted ventilation. One of the disadvantages is the fact that they do not deliver high concentrations of oxygen without special adaptors or attention to technique. In order to investigate the variables affecting oxygen delivery, we designed a study to determine the fractions of delivered oxygen (FDO2) under varying ventilating techniques and conditions. METHODS: We designed special wooden box, in which the Laerdal resuscitator bag had been. We measured the fractions of delivered oxygen with or without reservoir bag in various tidal volumes, respiration rates and oxygen flows. RESULTS: Without reservoir bag, the fractions of delivered oxygen were increased up to only 73% in spite of 15 l/min oxygen flow. With reservoir bag, the fractions of delivered oxygen were increased up to nearly 96% in 5-7.5 l/min oxygen flow. CONCLUSIONS: While using the Laerdal resuscitator bag, it is desirable to adapt reservoir bag and supply 5 l/min oxygen in conventional ventilation and 7.5 l/min in hyperventilation minimally for higher fraction of delivered oxygen.
