The purpose of this study was to investigate effect of water extract of Patriniae Herba on the poliferation of human cancer cell-lines. The effects of Patriniae Herba on the poliferation of A43l, HeLa, MOLT-4, K562 cells, Balb/c 3T3 cells, mouse thymocytes, splenocytes and human lymphocytes were estimated by MTT colorimetric assay, The results were as follows; 1. Patriniae Herbs did not effect A43l, HeLa, MOLT-4, K562 cells. 2. The cytotoxicity of mitomycin C on MOLT-4 cells was increased by the combination of Patriniae Herba. 3. Patriniae Herba inhibited the proliferation of Balb/c 3T3 cells. 4. Patriniae Herba stimulated the proliferation of thymocytes. 5. Patriniae Herba stimulated the proliferation of splenocytes. 6. Patriniae Herba stimulated the proliferation of human lymphocytes.

Nerve allografts as a bridge through which lost nerve can regenerate is useful in the repair of peripheral nerve defect resulting from trauma, neoplasm and leprosy. But immunological rejection and complicated scar formation is an unaboidable problem in the application of allogenic nerves. This article is intended to study histopathological and immunohistochemical response after fresh allogenic sciatic nerve grafts in rats. 12 male Sprague- Dawley rats were used as the experimental animals. A 2cm skin incision was made on the lateral aspects of limb, parallel to the femur. 1cm-long sciatic nerve trunk taken from the one rat was resected at the middle of the to high, and it was transplanted to the same area of the other rat with perineural suture method. Observation was made at the postoperative 1, 3, 8, 16 day. The results were as follows. 1. Histopathologically, destruction of the perineural sheath was observed only in 1-day group. 2. Mild degenerative changes of the nucleus and cytoplasm of Schwann cells were ovserved in the 1-day and 3-day groups. These changes gradually resolved. 3. Hollow space phenomena of the nucleus and cytoplasm of schwann cells were observed. The response was mild in the 1 day and 3 day groups, and moderate in the 8 day group. The phenomena were not identified in the 16 day group. 4. Immunohistochemical studies revealed pan T cells and cytotoxic T cells in the 1 day group. Increased numbers of cytotoxic T Cells and helper T cells were observed in the 3 and 8 day groups. 5. According to these results, after transplantation of fresh allogenic sciatic nerve an inflammatory response was observed up to 8 days and then gradually resolved. Degenerative changes were more severe up to 8 days, but an the 16th day they had resolved histopathologically and immunopathologically.

2배위 및 3배위 황화합물들이 가수분해될 때 무기산이나 할로겐화 이온과 같은 친핵체에 의해 촉매작용을 받는다는 사실이 알려져 있다. 이들 화합물들의 산촉매 가수분해반응 메카니즘은 식(1)에서 보는 바와 같이 반응 중심인 황 원자 주위에 다섯 개의 전자쌍이 관련된 초원자가 중간체(hypervalent intermediate)가 관련된다는 사실이 흥미의 대상이 되어 오고 있다.

This survey for the purpose of finding out the effects of Golf as a continuative exercise on the mental stress has made the following conclusion with the research results having examined the effects by using the stress measuring paper to the subjects of the amateur Golfers consisted of 183 (Male 98 and Female 85) in Chonbuk province. 1. The effects on the total stress levels as a continuative exercise shows that the male subjects (105.96±14.38) is higher than the female (104.05±11.49). 2. In the following stress levels the Golf has the effect showing that the male (19.72) is higher than the female (19.54) in the mental factor, and the male (35.74) is higher than the female (34.82) in the emotional and the anxiety factors. And it shows statistical significance (p=0.79). 3. The effects of Golf as a continuative exercise on the total stress levels according to the subjects' career shows that the group (108.03) whose career is more than 83 months is higher than the group (101.68) whose career is more than 49-82 months. 4. The effects of Golf as a continuative exercise on the mental stress in the following levels shows that the group (20.31) whose career is more than 83 months is higher than the group (18.71) whose career is more than 49-82 months in the mental factor, and the group (28.30) who career is more than 83 months is also higher than the group (25.76) whose career is more than 49-82 months in the physical and mental health factor respectively.

The most important factor of mobile robot is to build a map for surrounding environment and estimate its localization. This paper proposes a real-time localization and map building method through 3-D reconstruction using scale invariant feature from monocular camera. Mobile robot attached monocular camera looking wall extracts scale invariant features in each image using SIFT(Scale Invariant Feature Transform) as it follows wall. Matching is carried out by the extracted features and matching feature map that is transformed into absolute coordinates using 3-D reconstruction of point and geometrical analysis of surrounding environment build, and store it map database. After finished feature map building, the robot finds some points matched with previous feature map and find its pose by affine parameter in real time. Position error of the proposed method was maximum. 8㎝. and angle error was within 10°.

목적: 위식도역류질환의 진단에 다채널 강내 임피던스-pH 검사의 유용성을 알아보고자 하였다. 첫째, 위식도역류질환에 대한 다채널 강내 임피던스-pH 검사의 유용성을 알아보고자 하였다. 둘째, 증상지수 양성인 환자를 대상으로 산역류 또는 비산역류와의 증상과의 관련성을 알아보고자 하였다. 대상 및 방법: 위식도역류질환이 의심되는 총 74명의 환자를 대상으로 다채널 강내 임피던스-pH 검사를 시행하고 결과를 분석하였다. 결과: 1) 보행성 24시간 식도 pH 검사상 위식도역류질환 양성인 환자 수는 20예였으며 산에 대한 증상지수 양성 (SI>50%) 환자 수는 15예였다. 나머지 39예 중 다채널 강내 임피던스 pH 검사로 측정한 비산 역류에 의한 증상지수 양성은 9예, 식괴 역류 총 %시간이 증가된 경우 8예로 총 17예가 위식도역류질환으로 추가 진단되었다. 2) 다채널 강내 임피던스 pH 검사로 측정한 증상지수 양성 29명 중에 산성 역류 시에는 산 역류 증상을 더 많이 호소하였고 비산성 역류 시에는 흉부작열감과 비심인성 흉통을 더 많이 호소하였다. 결론: 다채널 강내 임피던스-pH 검사는 위식도역류질환을 진단하는데 예민한 검사법으로 생각할 수 있고 역류물과 증상과의 상호관계를 알 수 있었다. Background/Aims: To investigate the usefulness of multichannel intraluminal impedance-pH metry (MII-pH) as a diagnostic tool for gastroesophageal reflux disease (GERD): 1) the usefulness of MII-pH to increase the diagnostic sensitivity of GERD; and 2) to analyze whether various GERD symptoms were correlated with acid and nonacid reflux in patients with a positive symptom index (SI). Methods: We retrospectively compared the results of pH-metry and the results of MII-pH metry from the data of MII-pH in 74 patients with suspected GERD. Results: 1) Twenty out of 74 patients were diagnosed with GERD by pH monitoring, and an additional 15 cases had a positive SI (> 50%). Out of the remaining 39 patients, a positive SI for nonacid reflux was present in nine patients. A total of 17 cases were added to the GERD diagnosis including eight patients who showed an increase in total bolus reflux time percentage by MII-pH. 2) Regurgitation was more commonly observed with acid reflux in 29 patients with positive SI, but heartburn and noncardiogenic chest pain were more commonly correlated to nonacid reflux. Conclusions: Multichannel intraluminal impedance-pH metry is a sensitive method for the diagnosis of GERD and informs the correlation between symptoms and reflux.

Paradoxical embolism is a kind of stroke caused by embolism of thrombus of venous origin through a lateral opening in the heart, such as a patent foramen ovale (PFO). Although the most frequent manifestation of paradoxical embolism is cryptogenic stroke, noncerebral paradoxical embolism is also associated with PFO. We experienced a case of cryptogenic renal infarction in a previously healthy 70-year-old man. He had no cardiac thrombus on transthoracic echocardiography and electrocardiogram revealed a normal sinus rhythm. Because it was cryptogenic renal infarction, we performed transesophageal echocardiography with microbubble test. Microbubble test using agitated saline proved the presence of right-to-left shunt and patent foramen ovale was diagnosed. We also performed lower leg doppler ultrasonogram, but there was no evidence of deep vein thrombosis. Although only the presence of a right-to-left shunt is not enough to establish the diagnosis of paradoxical embolism, it is uncommon for the source of the embolism to be identified. In this case, we concluded that paradoxical embolism is the cause of renal embolism. We report paradoxical renal embolism through PFO with review of relevant literatures.
