Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

Background: The diseases are getting increasingly chronic as the fast development of medical and scientific technical advances prolong the human life span. Among many chronic diseases, the apoplexy leads to partial paralysis, speech disorder, perception disorder and paresthesia and motor disturbance. It also causes mental disorder to patients. This research was aimed to check the level of stress perceived by apoplexy patients according to the socioeconomic factors and neurological manifestations. Method: Applying the Neuman's stress measurement, we surveyed the stress level of 150 inpatients and outpatients who have been currently taken care of by the departments of neurology, neurosurgery and rehabilitation at a university hospital and two general hospitals in Busan. Results: The stress level related to the socioeconomic factors is higher in patients who have low education level, low income level, and financial dependence on offsprings. The stress level related to the neurological manifestations is higher in patients who have multiple strokes, bilateral paralysis, and other neurological sequelae (language, sensory, memory, particularly, gaiting disturbances and dependencies for active daily living). Conclusion: The results suggest that poststroke patients are highly likely to suffer from mental stress by various socioeconomic factors and neurological manifestations. Therefore, it can be concluded that poststroke patients need not only medical treatments and rehabilitation procedures but also more proactive mental remedies and social supports considering patient's backgrounds and characteristics.

An ichneumonine genus, Probolus Wesmael, is first reported from Korea with P.fukuchiyamanus Uchida and P. cyanogaster Jeong. The former is new to Korea and the latter new to science. A key to the two species, and their descriptions and photographs of diagnostic characters are provided.

The purpose of this paper is to prevent driver from accidents by effectively notifying the driver blind spot warning in a short distance such as a narrow alley when using a two-wheeled vehicle. It is easy to see that two-wheeled vehicles are more fatal in the event of an accident. We analyzed and researched a safety warning device in low-speed driving to identify critical factors for drivers in two-wheeled vehicle driving, and to identify areas that can be improved. Based on the analysis and research, an experiment was conducted and a warning system was applied to the manufactured motorcycle.

Objectives:This study was to identify weight & metabolic changes in first-episode psychotic patients with antipsychotics use and investigate the differences of weight & metabolic changes between first-episode psychotic patients and controls with antipsychotics use. Method:In this retrospective study, twenty eight first-episode psychotic patients and twenty eight controls with schizophrenia, schizoaffective or bipolar disorder defined by DSM-IV criteria were included. Information about demographic and clinical characteristics of the subjects was gathered from the medical records. Also body weight, sBP, dBP, fasting glucose, lipid profile and WBC count were evaluated before and after antipsychotics use. Rogistic regression was conducted to assess factors associated with weight gain. Results:First-episode psychotic patients showed more weight and BMI changes than controls after antipsychotics use, and these changes continue over 12 months. On the other hand, there were no significant factors associated with weight gain. Conclusion:The results of present study suggest that antispychotics is one of the major causes inducing weight gain of psychotic patients and antipsychotics-induced weight gain is more vulnerable to drug-naive first-episode psychotic patients.

The gray vibrissae of Korean males(n= 189) between 15 and 75 years old and females(n=111) between 15 and 74 years old whop visited the department of otorhinolaryngology, Konkuk university Chungju hospital during 1996 to 1998, were counted for the purpose of estimating approximate age range in individuals of unknown age. The lowest age appearing gray hairs in both sexes was 15-year-old. The Pearson's correlation coefficient in both sexes was 0.490 (p<0.01). The age appearing gray vibrissae in females was slightly earlier than that of males, however, the differences between right and left sides of nasal cavity were insignificant. This method of counting gray vibrissae would be useful to estimate age range in personal identification together with other methods available until now.

The enzyme, squalene synthase, represents a branch point in the isoprenoid pathway capable of diverting carbon flow specifically to the biosynthesis of phytosterol and Triterpenoid. Transgenic Eleutherococcus senticosus plants were prepared by introducing the genes for squalene synthase derived from Panax ginseng (PgSS1), hygromycin phosphotransferase (HPT) and green fluorescent protein (GFP) through Agrobacterium-mediated transformation. Establishment of transgenic plantlets were confirmed by the presence of PgSS1 and HPT bands in the genomic DNA preparation using a PCR method and a Southern blotting. In addition, expression of the introduced GFP DNA was confirmed by observing green fluorescence of GFP from the embroyos. In the in vitro analysis of the PgSS1 enzymatic activities the transgenic plants showed to have 1.5 to 3 times higher than wild type plant, indicating that the PgSS1 genes was well over-expressed in the transgenic plants. Especially the PgSS1 acivities of embroyogenic cell was 120 times higher than those of plantlet.

국내의 토착형 말라리아는 삼일열 말라리아로, 1993년부터 재유행이 시작되었다. 말라리아의 중요한 합병증으로 드물지만 비장 파열이 있는데, 이는 주로 삼일열 말라리아에 의해서 발생되며, 국내에서는 1999년 말라리아에 의한 비장 파열로 비장 절제술을 시행한 예가 보고된 바 있다. 현재까지는 비장 파열이 있을 때 비장 절제술이 일차적인 치료로 되어 있으나, 비장 절제술 후의 감염 위험성이 크므로, 활력 징후가 불안정하거나, 출혈이 지속되는 소견이 보이지 않으면 가급적 보존적 치료를 하는 것이 추천된다. 저자들은 비장 파열이 동반된 말라리아 환자에서 비장 절제술을 시행하지 않고 보존적 치료로 호전된 예를 경험하여 보고하는 바이다. Plasmodium vivax has been the predominant Plasmodium species in the Republic of Korea and reemerged in 1993. Spontaneous rupture of malarial spleen is a rare but important complication associated with P. vivax infection. Only one case of spontaneous rupture of malarial spleen was reported in Korea in 1999. Splenectomy is still accepted as the treatment of choice in cases of spontaneous rupture of the spleen. But, considering increased risk of postsplenectomy infecion, splenectomy should be reserved for those patients with severe rupture or those with continued or recurrent bleeding. And conservative treatment should be considered in selected, closely monitored patients. We report a patient with P. vivax malaria who developed a spontaneous splenic rupture and was improved by conservative treatment.
