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.

Aplastic anemia is a disease characterized by pancytopenia in the peripheral blood and hypocellular bone marrow with the fatty infiltration. The causes of the acquired aplastic anemia were usually related to drugs and immune-related diseases. A 34-years old man was admitted due to general weakness. He has been going hemodialysis for 2 years because of end stage renal disease (ESRD) due to chronic glomerulonephritis. At admission, laboratory tests showed hemoglobin 6.2 g/dL, hematocrit 18.0 %, WBC 5,710mm (neutrophil 71.8%, lymphocyte 19.1%, monocyte 5.9%), reticulocyte 1.9%, platelet 93,000/mm, Fe 12.8 ug/dL, TIBC 204 ug/dL, ferritin 941.47 ng /ml, haptoglobin 0.72 g/L, vitamin B12 508.17 pmol/L, folate 24 ng/mL, total protein 6.54 g/dL, albumin 3.76 g/dL, Alk. pohsphatase 79 IU/L, AST 30.0 IU/L, ALT 39.7 IU/L, total bilirubin 0.57 mg/dl, BUN 79.4 mg/dl and creatinine 10.18 mg/dl. Peripheral blood smear showed the normocytic normochromic anemia with anisocytosis. Anemia was diagnosed but it was irresponsive to the recombinant human erythropoietin (EPO) and blood transfusion. In the bone marrow aspiration smear were there the hypoplastic myeloid and erythroid precursors. The bone marrow biopsy section showed the hypoplasia of all components (10-20%) and the fatty infiltration. We have experienced one case of the idiopathic aplastic anemia in a patient going through hemodialysis and we just report it with documentary records. 저자들은 혈액 투석 중인 환자에서 약물, 면역계 이상등의 원인을 발견할 수 없었음에도 재생 불량성 빈혈이 발생한 1예를 경험하여 문헌 고찰과 함께 보고하는 바이다.

This study was performed to investigate the effect of wax layer of bamboo on leaching of boron compounds. The removal of wax layer increased the loading of boron on bamboo surface. However, it had an effect on increasing the leaching rates of boron compounds during leaching test. The addition of water repellent retarded leaching of boron compounds to some extent from treated samples. Although borate/WRP system did not qualify borate treated wood for ground contact use, it showed a potential to improve performance of borate treated bamboo in above-ground applications not subjected to continuous wetting conditions.

In this study, to find out the seasonality of schizophrenic birth and to analyze the relationship between schizophrenic subgroups and their birth seasonality, we compared the monthly and seasonal birth distribution of 367 schizophrenic inpatients, admitted in the neuropsychiatric department of Maryknoll General Hospital from March 1982 to February 1987, to those of the general population as control group. And the monthly births of the subgroups classified according to the clinical subtype and course were also compared. The results of this study were as follows; 1) Comparing with the general population, the birth rates of schizophrenics were higher in November through March and the excess of birth rate during these months was 8.6%. In statistical analysis, there were significant excess of birth in January and significant deficit in June. And there were significant excess of birth in late autumn through early spring, especially in winter. The excess of winter birth rate was 4.6%. 2) In comparisions of the monthly births of each subgroups classified according to the clinical subtype and course (including 4 comparisions; paranoid type Vs. non-paranoid type, paranoid type plus schizoaffective Vs. the rest of the types, schizophrenia Vs. schizophreniform disorder, subchronic schizophrenia Vs. chronic schizophrenia), there were no statistically significant differences in any comparisions. Therefore we confirmed the seasonality of schizophrenic births that there was an excess of winter or spring births among schizophrenics but the hypothesis that seasonality of birth is associated with an increased risk for a subtype of schizophrenia was not supported.

This paper is results of numerical works of investigating effects of horizontal drain arrangements on vacuum consolidation. Extensive numerical analyses were carried out to find the appropriate arrangements of horizontal dram of vacuum consolidation. Commercially available program of CRISP. well know-n to be good to modelling the behavior of clay- material, was used Cam-clay model, based on the Critical State of Soil Mechanics(CSSM), was used to simulate the geotechnical engineering behavior of clay. Model test results carried out previously in the laboratory w-ere compared with numerically estimated results and it was found that results about consolidational settlement with times were in good agreements. Based on this confirmation. parametric numerical study was performed to investigate effects of horizontal drain arrangements on vacuum consolidation with changing the vertical and horizontal spacings between drains for the given soil properties and vacuum. The effect of distance of drain located in top layer from the surface of the ground on the settlement due to vacuum was also investigated. As a results of numerical analyses. appropriate arrangements of horizontal drain to maximize the consolidation settlement due to vacuum were found. The mechanism of vacuum consolidation about the vacuum pressures being transferred to the effective stresses around drains was also evaluated.

Currently, in the limited cases of early gastric cancer (EGC), endoscopic mucosal resection (EMR) is used for curative treatment. However, its completeness is still controversial. The purpose of this study was to review the suggested indications of EMR. We retrospectively analyzed 234 patients with EGC who underwent curative (RO) gastrectomy. The enrolled cases were further classified into mucosal and submucosal types, and mucosal EGC were further classified according to the size, gross type and histologic pattern. 133 patients had mucosal cancers and 101 patients submucosal. The overall incidence of positive lymph node was 14.1% (33/234), the incidence of mucosal cancer was 8. 3% (11/133), which was significantly lower than that of submucosal, 22% (22/101). Of 133 patients with mucosal EGC, 90 were smaller than 2㎝ in size and the incidence of lymph node metastasis was 5.6% (5/90), compared to 43 of larger than 2㎝ with the incidence of 14% (6/43). According to the gross type classification of mucosal cancer, incidence of lymph node metastasis in protruded type (EGC type Ⅰ, Ⅱa, Ⅰ+Ⅱa) was 15.4% (4/26), nat type(EGC type Ⅱb) 2. 9% (1/35), depressed type (EGC type Ⅱc, Ⅲ) 8.3% (6/72). Lymph node metastasis in differentiated type of mucosal cancer was 6.9% (5/72) and undifferentiatcd type 9.8% (6/61). In this study, there was no single indication free from lymph node metastasis, It is thought that the selection of EMR for the curative treatment of EGC should be considered carefully and more clinical studies with long-term follow up are necessary for EMR to be generally acceptable.
