For the purpose of developing Korean Herbalogy with the plants of Rosaceae which grow wild and is planted in Korea, the these and writings on herbalogy, from literature of successive generations, have been thoroughly investigated and the results obtained as follows: 1. There were totaled to 36 genera and 262 in Korea and among them medicinal plants are 27 genera, 117species, some 44% in total, but the number of species may be added because of the similiar plants. 2. According to sum of 262 species in Rosaceae family, they were classified into Agrimonia genera 3, Potentilla genera 26, Prunus genera 48,pyrus genera 17, Rosa genera 24, Rubus genera 28, Sorbaria genera 17, Spiraea genera 20. Thus it was noticed that Prunus genera was the main kind in total. 3. According to the oriental names which can be used for medical purpose, the medicinal plants belonging to the Rosaceae family were classified as Herba 24, Radix 43, Foilum 31, Fructus 48, Semen 11, cortex 14, Lignum, Ramulus;12 each Flos 3, pericarpium 3, resina 2, the others 6. so Fructus is 24% of all and it is the most applied in the clinical treatments. 4. According to nature and flavour of medicinal plants, they were classified into balance 84, warmth, heat; 44 each, cold, cool; 35 each bitter taste 79, sweet taste 74, sour taste 61 thus it was noticed that balance and bitter taste is the main in nature and flavour of medicinal plants 5. According to meridian tropism of herbs they were classified into liver meridian 50 lung meridian 28, stomach meridian 22, spleen meridian 20, heart meridian 19 thus it was noticed that liver meridian is the main kind 6. According to the Properties and Principal curative action, they were classified into drugs for treating detoxicant 72, drugs for treating febrifugal 55, drugs for invigorating blood circulation 53, drugs for removing dampness 46, drugs for expelling wind and drugs to stop bleeding 38 each, drugs to cure tramatic swelling and drugs for relieving pain 36 each. Thus it was noticed that drugs for treating detoxicant and febrifugal was the main kind 7. It was researched that toxic drugs include minor toxin were 10 kinds From this result, it was revealed that Fructus was the main kind in the plants for medical purpose of Rosaceae. and toxic plants was slightly poisonous that it will be used for clinical treatments more easily. It is considered that many experiments and clinical approaches must be continued to use Rosaceae plants widely.

The permanent magnet machines have the advantages of high efficiency and power density, features very improtant for air-borne applications with their requiement of no external dc supply for rotor excitation, in addition, a very lower synchronous reactance thus making it a stiff source of power with a higher steady state and more transient capability than ist counterpart, the wound rotor type. In this paper, The permanent magnet synchronous machine is taken as a power source in the variable speed constant frequency power conversion scheme with converter-inverter system. All digital routines are excuted in the sampling time of 100 micro second by a DSP Board (TMS320c25) with A/D converters, which is detect the load current, capacitor current and DC link voltage at a sudden load change and to compute the predicted current. In one sampling interval, two optimal space voltage vectors as well as tow zero voltage vectors are employed so that the capacitor current may follow the reference. As a result, sinusoidal output constant voltage is obtained while swiching frequency is constant, and experimental results are presented, which shows the effectiveness of the proposed control method.

이용욱,김성민,구태완,이혜린,강일호,한길로,이혜승,황적준 大韓法醫學會 1999 대한법의학회지 Vol.23 No.1

The hypervariable short tandem repeat(STR) locus D12S391 was investigated in a Korean population. A total of 14 alleles were detected by size under denaturing conditions in 517 unrelated individuals. To confirm all of the alleles detected in a Korean population, a total of 34 fragments were sequenced. Prior to allele designation, we constructed the allelic ladders containing 11 alleles sequenced in this study. Allele 18 is the most common with a frequency of 0.281 in Koreans, and one variant allele 19.3 which have been confirmed by sequencing, was detected. The observed heterozygosity, the power of discrimination (PD), and the mean exclusion chance (MEC) for the locus D12S392 is 0.781, 0.946 and 0.652 , respectively. No deviation from Hardy-Weinberg equilibrium was observed in a Korean population (p=0.557). In the 424 meioses in 105 Korean families confirmed using other 17 STR loci, no mutation was detected in locus D12S391. The STR locus D12S391system is useful both for the analysis identification and parternity.

Bismuth nanoparticles were prepared by electrochemical reduction of bismuth oxide nanoparticles. Bismuth nitrate (Bi(NO3)3·5H2O) and ammonium hydroxide (NH4OH) were used as starting materials and precipitant to synthesize bismuth hydroxide. After decomposition of bismuth hydroxide at 800℃ , spherical bismuth oxide nanoparticles with a diameter of 200 nm were obtained. Bismuth oxide nanoparticles were electrochemically reduced to bismuth nanoparticles below −1.0 V (vs. SCE) in a 0.1M KOH solution. The morphology and structure of the nanoparticles were analyzed with a scanning electron microscope(SEM), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD). The bismuth nanoparticles prepared were applied for the simultaneous determination of lead and cadmium by square wave anodic stripping voltammetry. Screenprinted bismuth nanoparticle electrodes presented well-defined, reproducible and sharp stripping signals.

N/A Background: Bleeding is common complication and a leading cause of death in cirrhotic patients, Accelerated fibrinolysis and coagulation inhibitor were contributing factors to bleeding. Method: In a study of 20 normal control and 20 liver cirrhosis (10 liver cirrhosis without esophageal variceal bleeding and 10 liver cirrhosis with esophageal variceal bleeding), we tried to evaluate fibrinolytic activity 8r inhibitory factors of the coagulation in liver cirrhosis and to find correlation between variceal bleeding and parameters of fibrinolysis % coagulation inhibitors. Results: 1) t-PA antigen was significantly increased(p <0.05) in patients with liver cirrhosis(22.2±12.5ng/ml) than in normal contro1(3.9±1.9ng/ml), but there was no statistically significant increase in cirrhotic patients with bleeding(26.2±13.8ng/ml) as compared to cirrhotic patients without bleeding(18.2±10.1ng/ml). 2) Euglobulin fibrinolytic activity was significantly higher(p<0,05) in patients with liver cirrhosis(145±37.6 BAU) than in normal control(91±7.8 BAU), but there was no statistically significant increase in cirrhotic patients with bleeding(150±64 BAU)as compared to cirrhotic patients without bleeding(131±22 BAU). 3) The activities of protein C was significantly lower(p<0.05) in patient with bleeding(41±9%) than in patient siwthout bleeding(54±18%). 4) The activities of protein S was lower in patient with bleeding(62±18%) than in patients without bleeding group(77±17%), but there was no statistical significance. 5) There was a significantly linear correlatian between t-PA antigen and euglobulin fibrinolytic activity in normal control and in patients with liver cirrhosis (r=0.807, p<0.01). Conclusion: Fibrinolytic activity(t-PA k euglobulin fibrinolytic activity) was increased in cirrhotic patients, but there was no statistically significant increase of fibrinolytic activity with relation to esophageal variceal bleeding. The activities of protein C was significantly decreased in liver cirrhosis with relation to esophageal variceal bleeding.

황경호,길선희,김성열 대한마취과학회 1986 Korean Journal of Anesthesiology Vol.19 No.3

A 18 year old male with myesthenia gravis, Osserman Adult B type, underwent thymectany under general anesthesia combining the use of the new competitive muscle relaxant, Vecuronium, with initial dose of 0.08mg/kg. Neuromuscular blockade of Vecuronium in this myasthenic patient was monitored carefully from induction to postanesthetic period and it was compared with neuromuscula blockade of vecuronium(0.08mg/kg) and pancuronium (0.08mg/kg) in non-myasthenic patient. In this dose of Vecuronium in myasthenic patient, easy toachive endotracheal intubation, it's duration action and recovery were markedly prolonged and delayed than those of nonmyasthenic patient and weakly approximated to those of pancuronium in non-myasthenic patients. Conclusively, the reduced dosage of vecuronium with careful neuromuscular monitering in myasthenic patient should be more effective and safe without any difficulties of anesthetic management and ventilatory support on post-operative period.

Bupivacaine주입에 의한 지속적 경부경막외마취의 임상적 연구

황경호,박욱,길선희 순천향대학교 1986 논문집 Vol.9 No.2

Continuous cervical epidural anesthesia with two different concentrations of bupivacaine had been performed in 43 cases for surgery of upper extremity and cervical spine. After the initial dose of 0.33% bupivacaine 15ml to Group I (n=22) and 0.5% bupivacaine 15ml to Group II(n=21) was injected respectively, we observed the circulatory and pulmonary functions to be changed, and evaluated the duration of those analgesic action. The number of spinal segment to be affected and the complications were checked. Statistical significance of changes after the initial dose in both groups was determined by student's t-test. All values are impresed as mean±1S.D.. The results were as follows: 1) Circulatory functions; Systolic B.P. and pulse rate were decreased by 10-15 torr and 5-6 beats per minute respectively between 10-30 minutes following the initial dose, which were statistically significant in both groups. 2) Pulmonary functions; The diminution of minute volume showed to 20% and a rise of PaCO2 level to 5-6 torr respectively between 30-60 minutes following the initial dose, which were statistically significant in both groups. There were no significant changes in self respiration and respiratory rate in both groups. 3) The duration of analgesic action was 72.3±25.7(min) in Group I and 83.5±28.5(min) in Group II which was not statistically significant between two groups, and the number of affected spinal segment at one hour following the Anesthusia was 8.7±2.0 in Group I and 10.5±2.4 in Group II which was statistically significant between two groups. 4) Complications; a. Hypotension(below 80torr in systolic pressure) was appeared in 5% of all patients. b. Bradycardia(below 60 beats per minutes) was appeared in 25% of all patients. c. Inadvertent dural puncture was developed in only one patient. In conclusion, the 0.33% bupivacaine as well as 0.5% bupivacaine were enough for those analgesic effect in the above mentioned surgery even though the duration of analgesic action was about 10 minutes shorter in Group I than that of Group II. The cardiopulmonary function was clinically rather stable in Group I than that of Group II. Therefore we thought 0.33% bupivacaine was satisfactory for the clinical practicality in the cervical epidural anesthesia.
