Yong-Nam Han. Natural Products Research Institute, Seoul National University, Seoul, korea.Antithrombotic and Anticoagulant Components of Plants. Proceedings of International Symposium on East-West Medicine, Seoul. Page 149-152, 1999.-There are many kinds of herbal drugs related to "Blood"(現血藥)in the Oriental Traditional Medicines. In order to investigate the antithrombotic and anticoagulant activities of blood related medicinal plants, we have utilized some screening methods such as intrinsic and extrinisic anticoagulant and antiplatelet activities, in vivo and in vitro. In the first study to screen the antithrombotic activity, we have measured the bleeding time(BT), the whole blood recalcification clotting time(WCT) and the plasma reclaification clotting time(PCT), successively, after orally administering an extract of a herbal medicine to rats. An intrinsic pathway anticoagulant drug should prolong all the three kinds of barometers, an extrinsic pathway anticoagulant one should prolong only BT, and antiplatelet one should prolong both BT and WCT. In the second study to isolate activ principles, we have measured in vitro the inhibitory activities on PCT, TF(tissue factor) and PA(platelet aggregation) for the intrinisic pathway anticoagulant, the extrinsic pathway anticoagulant and the antiplatelet activities, respectively. Recently, we have isolated weveral TF inhibitors(the extrinsic pathway anticoagulant) such as pubescenolic acid (20-epi-pomoli acid) from Ilex pubescens roots (毛冬靑), zivu-glycoside Ⅱ and pomoli acid from Sanguisorba officinalis roots (地楡), and compund I and X from Cinkgo biloba leaves(銀杏藥).Their anticoagulant activities were evaluated in vivo and in vitro on rat brain and lung tissue, respectively. Rat TF was measured by its procoagulant activity using one stage clotting assay method modified by us. Ziyu-glycoside Ⅱ, one of the most potent TF inhibitor was effective in vitro, but not in vivo. Thus, we prepared a derivative, named ZYM201, which strongly inhibitied the rat brain TF activity in vivo, Oral administration of ZYM201 enhanced atherosclerotic index in dietary, streptozo-tocin-induced, and alcoholic hyperlipidemic rats (unpublished data).

We have usually experienced bone conduction impairment in chronic otitis media, but it is unclear that raised bone conduction threshold is due to the reflection of cochlear dam- age and / or Carhart effect ( an artificial elevation of bone conduction threshold due to conductive defect ) or both. The purpose of this study is to verify the influence of the artificial elevation of the bone conduction threshold in chronic otitis media and to estimate Carhart effect. A total of 336 cases of tympanoplasty with unilateral chronic otitis media without any other causes of sensorineural hearing loss was studied. The average threshold levels of the bone conduction in diseased ears ranged from 18.5dB at 4kHz to 12.1dB at 250Hz The longer duration of the disease, the larger perforation size, the more severe damage of the middle ear structure and the presence of the cholesteatoma made bone conduction threshold increased. The postoperative thresholds of bone conduction were Improved in 36 cases (40.4%) of the 89 cases that underwent operation with type I tympanoplasty technique without electrie drilling. The degree of the maximal improvement was 14.3dB at 2000Hz and the minimum was 8.8dB at 250Hz. but these result did differ from a statistically significant degree. The result suggest that the bone conduction threshold in chronic otitis media is elevated artificially by conductive defect and improved by successful reconstructive surgery.

In order to determine whether vegetation would be one of the factors for the selection of otter home range, vegetation structure and other potential factors were studied in Hwacheon, Korea. Thirteen sites, otter’s activity found and not found, were investigated in North Han River and connected tributary streams of Hwacheon-gun. Three types of vegetation were classified by cluster analysis, which is short grass, tall grass and shrub type. Vegetation zone of each channel is composed of either one type, or mosaic of tall grass and shrub type. Short grass type is common in Lake Paro and upper North Han-river where water level is highly variable throughout a year. Therefore, annual species such as Persicaria nodosa, Fimbristylis dichotomam and Chenopodium ficifolium are the most dominant. Shrub type is common at the downstream sites of Jichon stream and along mainstream of North Han River down Lake Paro. A shrub species, Salix koreensis, is the most common. Tall grass type is dominant occupying the most vegetation zone of the tributary channels. Phragmites japonica is absolutely dominant. Due to its dense cover, a few plant species are co-existed. Otter activity was found in all three vegetation types and no marked activity was found at some sites of tall grass type. There is no difference in species composition and physiognomy between tall grass sites with and without otter activity, while it shows significant difference in fish availability between two groups. Overall we found that home range of otters in the region is along the mainstream and downstream of tributary streams with high fish availability in all vegetation types and in various human activity levels.

The purpose of this study was to investigate where a feedback(self-controlled) schedule controlled by learner would be a more effective means of delivering feedback than any predetermined feedback schedule. Subjects(n=60) were randomly assigned to one of five conditions : Control condition, 50% relative frequency feedback condition, bandwidth feedback condition, self-controlled performance feedback condition, and yoked control condition. Experiment was designed to determine the optimal feedback condition for performance and learning of underhand toss. In experiments, subjects performed 50 acquisition and two retention trials blocks were analyzed with two experimental conditions to which they had been assigned. Data obtained from all subjects in five acquisition and two retention trials blocks were analyzed with two separate analyses of variance for each of four error scores. Analysis performed on the acquisition trials were a 5×5(condition ×trial block) analysis of variance(ANOVA) with repeated measures on the second factor. The retention trials were analyzed in a 5 ×2(condition ×trial block) analysis of variance with repeated measures on the second factor. Dependent measures were absolute error(AE), and variable error(VE). In conclusion, it should be stressed that the results of this study do support the guidance hypothesis of feedback and these findings showed that self-controlled subjects tend to produce improvements in the learning of underhand toss.

Two polymorphic loci, so- called FS106 and FS185, have been isolated from the human genome, using a multilocus probe pV47-2, which is extensively used in Korea for forensic investigation such as resolving paternity disputes. Among the several plaques selected from λ Fix-II genomic libraries, fourteen clones have been characterized. Restriction maps of 14 clones were constructed to define the flanking as well as repeat parts. The repeat-free flanking DNA fragments were tested for single locus specific polymorphism, and repeat containing DNA fragments were sequenced for the design of PCR primers. None of the repeat-free flanking DNA fragments was not shown any polymorphisms by RFLP analysis. The (GGT)??-rich sequences in most of repeat containing DNA fragments were identified by sequencing analysis. Most of repetitive sequences consists of major units of (GGT)??, but a regular repetition pattern can not be found in all clones. Two sets of primers designed from flanking sequences of repeat containing DNA fragments were shown length polymorphisms by PCR analysis, when tested in 50 unrelated individuals. Three and four alleles were detected at FS106 and 0.58 for FS185. In addition, two loci, FS106 and FS185, have been mapped on chromosome 5 and 3, respectively, by somatic cell hybrid analysis.

Plasmacytoma is an uncommon tumor that arises from malignant proliferation of a type of B-cell lymphocyte. Most plasma cell tumors present as multiple myeloma. Solitary plasmacytomas are classified as medullary or extramedullary. Among them, extramedullary plasmacytoma consists of 4% of all plasma cell tumors and is found predominantly in the head and neck region. The most frequent sites are the paranasal sinus, nasal cavity, and nasopharynx but, extramedullary plasmacytoma originated from nasal septum is rare. If histologic diagnosis of plasmacytoma is confirmed, all screening tests are necessary to rule out multiple myeloma. The primary treatment is radiotherapy, but surgery may also be required. We experienced a case of extramedullary plasmacytoma that originated from the nasal septum in a 62-year-old woman. She was treated with combined therapy. Systemic evaluations were done and there was no evidence of systemic involvement. After treatment, she is now well without any symptoms and evidence of recurrence. So we report this case with a review of the literature.

Pyromellitic dianhydride(PMDA) 와 Oxydianiline(ODA)를 N, N-dimethylacetamide (DMAc)에 녹여 Polyamic acid(PAA)를 2단계 열이미드화법으로 제조하였다. 제조된 폴리이미드 막의 이미드화도는 FT-IR에 의하여 분석되었다. 또한 PAA의 농도를 10~30wt%로 변화시키며 합성하여 열이미드화 시킨 후 농도에 따른 단면의 상태를 SEM사진을 통하여 관찰하였다. 농도 변화에 따른 밀도와 T_g의 변화는 혼합액체부상법과 DSC로 분석되었다. 열처리 온도를 증가시킬수록 이미드화도는 증가되었고 PAA의 농도가 증가할수록 필름의 단면이 치밀해짐을 알 수 있었다. 또한 제조된 PMDA-ODA 폴리이미드의 T_g는 215℃ 이었다. Polyamic acid(PAA) was synthesised with Pyromellitic dianhydride(PMDA) and Oxydianiline (ODA) in N, N-dimethylacetamide(DMAc). PMDA-ODA polyimide membranes were obtained by two step thermal imidization, and the degree of imidization of polyimide membranes was observed by the FT-IR. After the thermal imidization through the concentration of varied synthesis of PAA, 10~30wt%, SEM photographies of section state were observed. The density and glass transition temperature on the varied concentration were replace with investigated test of density and Differential Scanning Calorimetry (DSC). With increasing thermal treatment temperature, the degree of imidization was increased. While the concentration of PAA increases, the section of membrane was densed. The glass transition temperature was maintained to be constant(215℃) within the PAA concentration range.
