2.Development of Blood Bank Management Program with Personal Computer for Small to Medium Size Hospitals.
Korean Journal of Blood Transfusion 1996;7(2):197-205
A recently increased need to a computerized program for correct management of grouping and dealing of bloods at small to mize hospitals made us develope the blood bank management program with a personal computer. Some hardwares(PC 486, bar code reader and printer) and softwares(Microsoft Foxpro version 2.5 for main development and Hanmac 2.5 for Korean BIOS) were used as materials, and frequent upgrades were performed during the develpment period. The program was consisted of eight main functions including grouping, input, output, reinput and expire of bloods, and autotransfusion, apheresis and directed transfusion. The program may be a good tool to reduce blood accidents and to enhance quality of blood banks at small to medium size hospitals.

We have retrospectively analyzed the clinical and radiological outcome in 22 cervical spondylotic myeloradiculopathy patients who underwent combined front anterior decompression and fusion) and back (open door laminoplasty) surgery between Mar. 1991 and Jan. 1995. Clinical symptoms were evaluated by Japanese Orthopaedic Association(JOA) score and the recovery rate. Plain radiogram and MIR were taken before and after surgery, and then the cervical curvature, change of body to canal ratio and the A-P compression ratio of the cord were measured and compared to the clinical symptoms. Results : The mean JOA score increased from 10.1±3.3 preoperatively to 14.7±1.4 at the final follow-up with a mean recovery rate of 64.4%. No patients deteriorated as a result of the combined procedure. Post-op. radiograms showed an increasement of body to ratios (average 0.69±0.09 pre-op. to 1.0±0.13 post-op.) and maintenance or recovery of cervical Lordosis. On MRI, the A-P compression ratios of the cord were increased with recovery of subarachnoid space after the operation in most cases (average 38.4±7.6 pre-op. to 55.7±7.2 post-op.). Conclusion : This combined procedure safely and effectively resulted in decompression of the spinal cord and good functional recovery in patients with 1) anterior and posterior pathology, 2) narrow spinal canal and large spondylotic bar or herniated disc encroaching the spinal canal more than 5mm, 3) narrow spinal canal and kyphotic deformity, 4) narrow spinal canal and segmental instability, 5) multisegmental cord compression and severe radiculopathy.

Journal of the Korean Radiological Society 1985;21(3):384-391
Eighty-eight patients who presented with a variety of head and neck symptoms were examined with intravenous oritraarterial digital subtraction angiography (IV or IA DSA), using the DSA equipment developed by Seoul NationalUniversity Hospital. A grading system was used to evaluate the ability of DSA to answer specific diagnsoticquestions. Diagnostic information without need of further study was obtained in 71% with IV DSA, in 86% withaortic arch DSA and in 81% with selective arterial DSA, showing a total of 79% of diagnostic accuracy with DSA. Itis concluded that IV DSA is useful in the evaluation of the cervical carotid and vertebral arterial disease, andpituitary mass lesion, while IA DSA is useful in the evaluation of the cervical carotid and vertebral arterialdisease, and pituitary mass lesion, while IA DSA is useful in the evaluation of most of the intracranial lesions,spinal arteriography and intra-arterial embolization. DSA is both an accurate and safe imaging modality in thestudy of head and neck diseases.

Pulmonary artery sling is an uncommon and potentially lethal vascular anomaly that can produce airway obstruction. Despite the availibility of a corrective operation, the mortality rate remains very high due to the high incidence of associated obstructive anomalies of the tracheobronchial tree. We experienced a 70-day-old male infant who was admitted to our unit because of sudden dyspnea, cyanosis, coarse expiratory wheezing and inspiratory stridor. At first, he was treated with bronchodilator and steroid under the impression of infantile asthma, but the symptoms went on without interval change. We performed magnetic resonance imaging study followed esophagography and two dimensional echocardiography. Finally he was diagnosed as a vascular sling. We report this with a brief review and related literatures.

The fowl nematode Ascaridia galli employed in this experiment was obtained from the intestine of domestic fowls at the local market. The worms selected and washed several times in normal sterilized saline solution. Each about thirty of intact worms were incubated in 50 cc volume of special incubation flasks with incubation mixture consisting of 10 cc of Krebs-Ringer phosphate buffer (pH 7.4) to which were added universally labeled C14-glucose and non-radioactive carrier glucose so as to contain concentration of 200 mg per cent. The worms were allowed to incubation for 3 hours in Dubnoff metabolic shaking incubator at 38 C. After incubation period, respiratory CO(2) samples from central well of incubation flask were analysed for total CO(2) production rate and their specific activity of respiratory CO(2). Glycogen samples isolated from worms were analysed for uptake rate was determined by analyzing the difference of the glucose concentration in a medium before and after incubation period . Radioactivities of these series of experiments were counted by an endwindow Geiger-Muller counter as an infinitely thin samples. The quantitative analysis of C(14)-glucose utilized by Ascaridia galli was summarized as the following . The glucose uptake rate by A. galli was a mean value of 1.73+/-0.32 micro-mole per hour per gram of wet wt. and total CO(2) production rate by the worms averaged 8.44+/-1.11 micro-mole per hour per gram of wet wt. The relative specific activity of respiratory CO(2) (R.S.A CO(2)) averaged 2.68+/-0.38 per cent . Thus , a man of 2.68 per cent of total CO(2) production rate was originated from the glucose in the medium, therefore the rate of CO(2) production derived from medium glucose was a mean of 0.23+/-0.03 micro-mole per hour per gram of wet wt. Thus, the average value of 2.58+/-0.55 percent (R.G.D CO(2))of glucose utilized by the worms from the medium glucose was oxidized to respiratory CO2. The tissue concentration of glycogen in A. galli was a mean of 22.59+/-1.18 miligram per gram of wet wt or 2.26+/-0.123 percent per gram, and the turnover rate of glycogen pool yielded with a mean of 0.17+/-0.04 percent per hour or 0.037+/-0.006 miligram per hour per gram of wet wt. Therefore, a mean value of 16.37+/-4.04 per cent (R.G.D gly) of glucose was incorporated to the glycogen. These data account for that at least 18.95 per cent of the utilized glucose by the worms participated in furnishing the oxidation into respiratory CO(2) and the synthetic process into glycogen. According to the above data of the experiment, it is suggested in the metabolic process of glucose by Ascaridia galli that the synthetic process into the glycogen is more active than the oxidative process into the respiratory CO(2).

This study was undertaken to evaluate the status of human paragonimiasis in Kang Hwa Gun, Kyunggi Do, Korea from March 1973 to October 1975 by the use of intradermal screening test with Veronal buffered saline antigen. A total number of 7,352 (male 3,936; female 3,4l6) consisting of 3,447 primary school children, 2,689 middle school students, l,008 high school students of 9 Myuns out of 13 Myuns of this County and 208 residents of all age group in Kilgeong-Ri, Yangdo Myun were examined by the intradermal test with Paragonimus antigen. In order to detect Paragonimus egg, the sputum and the stool examinations were undertaken on the residents in Kilgeong-Ri. The infestation rate of crayfish with Paragonimus metacercaria was also examined in Konneung and Jeongha village in Kilgeong-Ri. The following results were obtained in this survey: As a whole, 16.6 per cent of the examiners showed positive reaction with sexual difference of 16.1% in male and 14.8 per cent in female. In age groups, the highest positive rate showed in middle school age group (17.1 per cent) than primary school (14.0 per cent) and high school age group (11.4 per cent). In regional differences of positive rates, the highest rate (28.4 per cent) showed at Yangdo Myun followed by Kilsang Myun (27.0 per cent), Hwado Myun (25.0 per cent), and Naega Myun(20.8 per cent). In the result of 208 residents Kilgeong-Ri, the positive of 36.1 per cent in male and 20.2 per cent in female. The highest positive rate showed in 10 to 19 age group (41.5 per cent). Among the residents in Kilgeong-Ri, Paragonimus eggs were detected in 11 residents by the sputum and the stool examinations. The infestation rate of crayfsh with Paragonimus metacercariae was 100 per cent (41 out of 41 crayfishes) in Konneung village, and 84.6 per cent (9 out of 13 crayfishes) in Jeongha village, Kilgeong-Ri The fluctuation of the infection rate of crayfish with Paragonimus metacercariae was decreased in Konneung village in 2 years after the treatment with Bilevon against 10 paragonimiasis patients.

BACKGROUND: In an effort t enhance long term patency of coronary bypass grafts, utilization of arterial conduits have been on an icrease. With the same objective, we have been using the right gastroepiploic artery (RGEA) in coronary artery bypass procedures since 1998. The current paper has been undertaken with the aim of assessing the apropriateness, problems, and short term results of using the RGEA as an arterial graft conduit by studying the postoperative clinical results of 100 patients than received coronary artery bypass grafting (CARG) with this artery. MATERIAL AND METHOD: Between May of 1998 and May of 1999, an analysis of the mortality, postoperative myocardial infarction, and the need for IABP insertion as a result of low cardiac output were made between 100 consecutive patients undergoing CABG with the RGEA. There was one postoperative death due to cerebral infarction. Postoperative complications/morbidity comprised myocardial infarction in 2, cerebral infarct in 3, reoperation due to bleeding in 1, mediastinitis in 1, and low cardiac output syndrome necessitating IABP in 3 patients. Complicatons related to harvesting of the arterial grafts were not experienced in any of the patients. CONCLUSION: The results of the current data show that utilization of the RGEA in CABG is not associated with increased mortality/morbidity and demonstrates satisfactory short term results suggesting the usefulnessof this conduit as an arterial graft.

The authors reviewed 1134 pediatric patients in the ebergency room in this hospital during 5 years period from Jan. 1979. to Dec. 1979. The results were obtained as follows: 1) Among the patients visiting the emergency room, the patients under 15 years of age were 6.1%(1134) of total emergency patients(18447). 2) The male to female ratio was 1.5:1. 3) The highest age group was in the 3-5 years, and the patients in this age group were occupied 23.8%. The age distribution showed that 57.7% was under the 5 years of age. 4) Seasonal distribution of patients showed high incidence in summer(June, July, and Aug.). 5) The most popular time of visiting the emergency room was between 8:00 P.M. to 12:00 P.M. at which time about 32.8% of patients were seen. 6) Distribution of cases as follows: Respiratory disease 35.7%, accident 177% and gastrointestinal disease 14.8%, in turn, kusted reseoectuvely in decresing order of frequency. URI was the most frequency, 25.1% of the total cases, The next diseases were diarrhea(9.5%), Bronchitis(6.6%) and febrile convulsion(6.3%) in turn decreasing order. 7) The most frequent case in various age groups was Respiratory disease. 8) Admission rate of total pediatric patients visiting ER was 7.4% by recommendation. Rate against recommendation of admission was 3.2% of total pediatric patients visiting ER. 9) We think the number of pediatric emergent patient is increasing due to understanding of community inhabitant.

The adult worm and plerocercoid larva(sparganum) of Diphyllobothrium mansoni and Moniezia expansa employed in this experiment. The adult worms were divided into three portions, i.e. immature, mature and gravid proglottids, and each proglottids were incubated in 50 cc or 250 cc volume of special incubation flasks with incubation medium consisting of 10 cc of 25 cc of Krebs-Ringer phosphate buffer (pH 7.4). The incubation medium was added C(14)-acetate and non-radioactive carrier Na-acetate so as to contain acetate concentration of 50 mg per cent. The worms were allowed to incubate for 5 hours in the Dubnoff metabolic shaking incubator at 38 C. After incubation period, the lactate and pyruvate appearance rate, total CO(2) production tate, the turnover rates were employed as pervious report(Seo et al., 1965). The quantitative analysis of C(14)-acetate utilized by the adult worm and plerocercoid larva of D. mansoni and M. expansa were compared and discussed in this report. According to these data of the experiment, it is impressed that the fatty acid such as acetate may play a role of major part of their metabolism in the adult worm and plerocercoid larva of D. mansoni , whereas minor part of acetate participated in the metabolism by M. expansa.
