In this study the antimicrobial spectrum and sensitivity of a liquid formulation of enrofloxacin against the major six pathogenic bacteria isolated from the diseased poultry in Korea were evaluated in comparison with ciprfloxacin (CFX), gentamicin (GM) and penicillin (PC). A liquid form of enrofloxacin, a test material and ciprofloxacin showed at least 83% antibacterial activity against all of six test pathogenic microorganisms at the fixed concentration of 10 ㎍/㎖. Gentamicin and penicillin revealed much lower antibacterial activity at the same condition. We evaluated the liquid form of enrofloxacin as having widespread antibacterial spectrum against poultry infections. The liquid form of enrofloxacin showed potent antibacterial activity, with the MIC range being 0.12∼2 ㎍/㎖ against Gram positives, 0.06∼2 ㎍/㎖ against Gram negatives and 0.5∼2 ㎍/㎖ against Mycoplasma spp. These values were equivalent to or somewhat higher than those of ciprofloxacin, but much lower than those of gentamicn and penicillin. This new liquid form of enrofloxacin would find its way in application of mixing with drinking water for the prevention and treatment of diverse infections in chickens.

We evaluated the efficacy of the liquid form of enrofloxacin against poultry respiratory and digestive infections, the major problems in the poultry industry, from diverse diagnosis viewpoints. Results obtained through this study were as follows: 1. The liquid form of enrofloxacin showed good acceptability to poultry owing to no abhorrence to the drug by chickens, which indicated its suitability for mixing in drinking water. 2. The application of the enrofloxacin formulation improved the productivity of the chicken farm to a great extent by lowering the death toll of chicken raised in the farm. 3. The use of the drug shortened the days to the market, and increased the body weight at the time of marketing. 4. Preventive and therapeutic effects of the liquid enrofloxacin were observed higher than ampicillin, a major antibiotic used in poultry farming. From above results, the liquid form of enrofloxacin would find its use for the prevention and treatment of digestive and respiratory infections, let alone the growth promotion and feed efficiency, especially in the chicken farming practice.

With a view to examining the habit and method in which old people maintain and improve their health, we consulted 551 men and 444 women who were over 65 years old, and concluded as follows: 1. Habit of eating It's been revealed that most of the old people keep a regular eating hour, control the quantity of meal or eat a little food, and prefer vegetables to meat. 2. Mental health Old people feel the necessity for mental health and most of them (about 80%) keep good mental health without becoming pessimistic. Their chief concenrs have turned out to be about their sons and daughters and their own health and finance. 3. Managing Good Health It has been revelaed that old people do not possess any special kind of secret to keep good health but taking plenty of rest, regular meal, and proper exercise, and many of them (about 60%) have been shown to eat invigorant food that they can easily get around their living area. 4. Physical Functions It has been revealed that many old people are conscious of some symptoms about their parts of body and about to percent of them suffers from neuralgia. Some measures like medical aid especially for old people need to be taken as soon as possible. As we have found that the health-keeping method of old people consists plenty of rest, proper exercise, and appropriate nutrition, we can conclude that the recreatonal and culture facilities and programs for keeping old people in good health should be developed. It is also necessary to study food that contribute to their health and develop ways to get rid of the stresses to which they are exposed in their daily life. Presides, it is natural that government found an administrative department to deal with these matters effectively.

The changes of serum and urine IgG levels were observed with the ELISA (enzyme-linked immunosorbent assay) at before and after treatment in human paragonimiasis. Serum and urine samples from 18 cases of confirmed paragonimiasis were tested at before and 12 months after treatment with praziquantel 75mg/kg t i d for 2 days. The ELISA was performed with veronal buffered saline antigen of crude Paragonimus westermani adult worm with the protein concentration of 14.3㎍/ml, peroxidase conjugated anti-human IgG (y-chains) rabbit serum and orthophenylene diamine as a substrate by micromethod. The results obtained were as follows; 1. Before treatment, the mean diameter of wheal size (mm) by the intradermal test was 14.3±3.9, 17 positive reaction out of 18 paragonimiasis cases showed and pseudopodia showed at the wheal by the intradermal test in the 11 out of 18 cases. But 12 months after treatment, the mean diameter was 13.6?4.6, 14 positive reaction out of 18 paragonimiasis which were treated effectively showed and pseudopodia showed in the 7 out of 18 cases. 2. Before treatment, the mean O.D. (optical density) values in the serum samples of 18 paragonimiasis cases was 1.60±0.37 and 18 positive reaction out of 18 paragonimiasis cases showed if we proposed the O.D. value 1.00 as a differential point of positive reaction. But 12 months after treatment, the mean O.D. values in the serum samples was 1.20±0.46 and 13 positive reaction out of 18 paragonimiasis which were treated effectively showed. 3. Before treatment, the mean O.D. values in the urine samples of 18 paragonimiasis cases was 1.22±0.53 and 17 positive reaction out of 18 paragonimiasis which were treated effectively showed if we proposed the O.D. values 0.50 as a differential point of positive reaction. But 12 months after treatment, the mean O.D. values in the urine samples was 0.26±0.24 and 3 positive reaction out of 18 p-aragonimiasis which were treated effectively showed. 4. Before treatment, the relation of the absorbance values between the serum (y-axis) and the urine (x-axis) samples made the regression equation; y-0.571x+0.913, and showed high correlations (r=0.75, n=18, p<0.001). In conclusion, these findings suggested that ELISA using a urine sample is more feasible and seems to be better suited for the evaluation of treatment effect.

Background: Anaphylaxis is a systematic allergic reaction, which may be fatal. However, despite its seriousness, its low level of incidence has prevented in depth studies. Thus, we analyzed the causes of anaphylactic shock in patients admitted in a tertiary hospital, observed its clinical symptoms, and formed a basis for adequate emergency treatment, as well preventive methods. Methods: The patients who visited Ajou university hospitals from June 1994 to May 2000(7 years) and who met the 1974 JAMA definition were selected for this retrospective study. The analysis of causative agents was made on the basis of clinical symptoms and the patients' chief complaints at the time of admission. Patients diagnosed with anaphylactic shock included those showing at least two types of IgE-mediated symptoms; and those with a simple rash or breathing difficulties were excluded from the study. Results: Of 36 patients, 22 were male and 14 female, Those below the age of 20 comprised 16.7% of the patients(6 patients), between 20 and 29 comprised 16.7%(6 patients), 30 and 39 comprised 25%(9 patients), 40 and 49 comprised 27.8%(10 patients), over 50 comprised 14%(5 patients). The overall percentage show 70% of the patients in active adult age group. Rash was the most common clinical symptoms(89%, 32 patients) and hypotension the second(75%, 27 patients), followed by respiratory distress, fainting, and arrhythmia. Causative agents were insect bites, including bee stings(15 patients), medication(12 patients), food(8 patients), and unknown(1 patients). Nine(9) of the 36 case, were diagnosed as having an atopic origin. Conclusion: Bee sting was the single most common cause in the insect criteria while penicillin & NSAIDs accounted for most of medication-induced cases. Food showed a varied distribution. An atopic origin was not a basis for anaphylactic shock, but did show a two-fold increase of prevalence. This study is the first of its kind in addressing anaphylactic shock, a potentially severe illness, over a period of 7 years.

본 연구의 목적은 동국대학교의 교수들이 수행하고 있는 교수학습 방식을 파악하고 각 방법들의 효과성을 교수들이 어떻게 인식하고 있는지를 알아 보고자 하였으며 창의적 교수학습방법개발에 대한 교수들의 요구를 파악하여 교수학습개발센터의 프로그램개발을 위한 기초자료로 삼고자 하였다. 수업방식에 있어서 전공, 교양을 막론하고 대부분이 강의식 수업방식이 높았으며(80.9%, 86%), 발표식, 토론식이 (14%, 18.6%) 실험실습 등이 그 다음으로 나타났다. 교수들은 전공과목보다는 교양수업에서 학생들의 요구에 맞는 수업 수업방식을 고려하고 있는 반면 수업방식의 효과에 대해 53%만이 효과적이라고 보고하고 있다. 교수들도 효과적인 강의방법 등 교수법에 대해 체계적으로 학습할 필요성을 느끼고 있었다. 강의 기술(교수방법)과 토론 중심 수업 방법에 대한 워크샵에 대한 요구가 가장 높게 나타났고 발표수업과 프로젝트수업 방법 등 강의식 수업 이외의 다른 수업방식에 대한 워크샵 요구도가 높았다. 그 외에 학교의 지원에 대해서는 첨단 수업 기자재 활용을 위한 보조자(조교)에 대한 요구도가 가장 높고 강의 운영을 위한 보조금, 개인별 상담 지원 순으로 요구도가 높게 나타났다. The purpose of this study was to comprehend the methods of teaching and learning carried out by the teachers of Dongguk University, and to find out how the professors found those methods effective. This research was also used to serve as a basis for the development of a more creative teaching-learning system to enhance better programs for the Professor Teaching-Learning Development Center. In teaching methods, regardless of classes for majors or for cultural enrichment, most of the courses were in the form of lectures (80.9%, 86%) followed by research and discussion (14%, 18.6%), with experiment and practical training coming in third. Although professors tend to choose a more student-oriented class method in distribution courses more than in major courses, it was reported that only 53% of the faculty claimed this class method to be effective. The faculty felt the need for professors to have more constructive learning in incorporating more effective teaching methods. The demand for professor workshops on teaching skills (teaching methods) and discussion oriented classes proved to be high, as well as the need for workshops on teaching methods other than lectures, such as research courses and project oriented class methods. Regarding other demands for university support, the demand for an assistant (assistant teacher) to help with the new technology equipment was the highest, followed by subsidies for course management and support in individual counseling.

Background : The cun measurement System, an essential and convenient method in locating acupoints, has been widely used in the practice of acupuncture. However, traditional cun measurement has been criticized for its lack of reliability. Objectives : The purposes of this study are to determine if one cun measured by the directional methods have a consistency with that of proportional methods and to investigate which factors are related with these differences, especially in forearm. Methods : The distance between the elbow crease and the wrist crease of forearm was compared to a reference value of one cun obtained by the directional method. In this method, one cun is one third of the distance between index finger and Small finger of a subject, measured at proximal interphalangeal joint. In addition, to investigate the factors influencing the differences between these two methods, we measured the height and body weight and calculated body mass index (BMI). Finally we analyzed the factors correlated with these lengths by linear regression test. Results : The results showed that one cun obtained by the directional methods were significantly different from one cun by the proportional methods in forearm. It was demonstrated that the length acquired with the directional method was more correlated with body weight and body mass index, while the length obtained by the proportional method was more correlated with the height.
