Two types of urine dipstick assays, Multistix-SG and Combur-9-test RL, were compared for compatibility, accuracy, specificity and predictive values of a positive and negative test in 501 patients urine and artificially prepared specimen. We found that the results of semiquantitative tests of Multistix-SG and Combur-9-Test RL performed were statistically similar in patients specimen. The urinary leukocyte estrase tests of Combur-9-Test RL assays compared with urine sediment microscopy in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative test 83.7%, 48.1%, 90.3%, 47.4% and 90.1%, respectively. The urinar nitrite tests of Comber-9-Test RL assays compared with urine culture tests, in regard to compatibility, sensitivity, specificity, and predictive values of a positive and negative tests were 90.3%, 19.4%, 84.7%, 53.8% and 94.1%, respectively. For the urinary protein, the sulfosalicylic acid method was the most sensitive test for any kinds of protein, and Multistix-SG appeared more sensitive than Compur-9-Test RL for the albuminuria. For the urinary bilirubin and glusose, two dipstick assays were similar in their diganostic efficiency. Finally in the urinary occult blood tests, Combur-9-Test RL assays was more sensitive than Multistix-SG.

To investigate mycorrhizal infection by arbuscular mycorrhizal fungi(AMF), samples of fine lateral roots were taken from the wild ginseng(Panax ginseng C.A. Meyer) naturally growing at various locations in Korea. Mycorrhiazal infections were studied by cleaning the root samples and staining fungal hyphae with frypan blue. Wild ginsengs for this study were graded by an appraisal committee consisting of 12 experts of Korea Mountain Ginseng Association. Following five quality groups were recognized: Heaven group(pure natural), Earth group (from seeding of wild ginseng), Man group(from seeding or seedlings of wild ginseng with slight environmental modification), unmarketable, and imported wild ginseng. Morphology of AMF was typical Paris-type which shows intracellular hyphal coils with rare vesicles and lack of arbuscules. Average infection rate of individual wild ginsengs was 58.3% and showed no differences among five quality groups. When portions of fine roots were quantified for mycorrhizal infection, 18.7% of the total length of the primary and secondary roots were infected by AMF. Wild ginsengs from Gyeonggi Province(84.2%), and from mountains lower than 1,200 meters above sea level(about 70%) showed higher infection rate, while the ginseng from Gyeongbuk Province(27.8%) had lower rate. Wild ginsengs at older age showed lower infection rates.

Delirium independently contributes to poor outcomes including prolonged hospital stays and increased risk of mortality. The reported prevalence of delirium in variety of medical and surgical hospital settings is from 15% to 70% ; delirium is, therefore, one of major reason for consultation that is required for psychosomatic interventions. This article reviews the psychosomatic interventions to treat delirium including 1) identification of risk factors and precipitating causes ; 2) non-pharmacological interventions, such as modifying treatment environment and educating patient's family and care-giver ; and 3) pharmacological approaches to control the various symptoms that are frequently presenting with delirium.

Necrotizing ulcerative gingivitis(NUG), necrotizing ulcerative periodontitis(NUP), necrotizing stomatitis (NS), and Noma (cnacrum oris) are rapidly destructive debilitating and potentially serious oral infection which considered to be different clinical stages of the same process. These have been collectively referred to as: Vincent's infection, infectious oral necrosis, or necrotizing gingivostomatitis(NG). Prevalence of necrotizing gingivostomatitis is $0.19{\sim}0.5%$ and peak incidence is 2-6 years of age. The etiology and pathogenesis of necrotizing gingivostomatitis have been associated with virulent bacteria and impaired host defense and the primary diagnostic signs are pain, interdental ulceration or necrosis, and gingival bleeding. Secondary diagnostic sign is pseudomembrane. This case report was about oral conditions and treatment of the patient who referred from the Dept. of PED and diagnosed a necorotizing gingivostomatitis.

When it is not easy to decide the credit scoring for some loan applicants, credit evaluation is postponded and reserve to ask a specialist for further evaluation of undecided applicants. This undecided inference is one of problems that happen to most statistical models including the biostatistics and sportal statistics as well as credit evaluation area. In this work, the undecided inference is regarded as a missing data mechanism under the assumption of MNAR, and use the bivariate probit model which is one of sample selection models. Two undecided inference methods are proposed: one is to make use of characteristic variables to represent the state for decided applicants, and the other is that more accurate and additional informations are collected and apply these new variables. With an illustrated example, misclassification error rates for undecided and overall applicants are obtainded and compared according to various characteristic variables, undecided intervals, and thresholds. It is found that misclassification error rates could be reduced when the undecided interval is increased and more accurate information is put to model, since more accurate situation of decided applications are reflected in the bivariate probit model.

Purpose : This study was to evaluate survival, failure patterns, and prognostic factors of stage I squamous cell carcinoma of the glottic larynx after curative radiation therapy. Materials and Methods : A retrospective analysis was done for 57 patients with glottic cancer who were treated with curative radiation therapy from June 1985 to November 1992. There were 55 male and two female patients. Patients' age ranged from 17 to 71 years(median 39 years). Radiation therapy was delivered five times a week, 2 Gy daily, total 66 Gy using 6 MV X-ray. Results : Complete response(CR) was noted in 51 out of 57 patients (89.5%) and persistent disease (PER) in six out of 57 patients(10.5%). The disease-free survival rates at 3 and 5 years were 72.9% and 63.8%, respectively. Seven failures were observed among 51 CR patients during follow-up. Salvage total laryngectomy for six recurred patients and partial laryngectomy for one recurred patient were done with successful results, i.e., all of them were actually salvaged. Among six PER patients, salvage total laryngectomy for two patients and partial laryngectomy for two patients were done and two patients refused operation. Following salvage surgery for the four PER patients, three were salvaged and one failed locoregionally. Among the 13 failures 10(76.9%) were salvaged with surgery. The ultimate local control rate at 5 years was 92.3% and overall 47 out of 57 (82.5%) patients were able to preserve their larynx. The 5-year disease-free survival rates were 85.5% for posterior lesions, and 61.6% for anterior lesions(P<0.05). Cord mobility, involvement of anterior commissure, field size, and T stage did not impact on disease-free survival. Conclusion : Considering the high percentage of voice preservation with initial radiotherapy, radiotherapy should be the first choice in the treatment of stage 1 glottic carcinoma.

Enteroviruses isolation were attempted from samples obtained from aseptic meningitis-suspected patients in hospitals in Busan during 2000-2002. Enteroviruses were found in 2 of 292 cases in 2000, 4 of 371 cases in 2001, 83 of 703 cases in 2002. In 2000, the isolated viruses were found to be echovirus serotype 11 and coxsackievirus serotype B2. Coxsackievirus serotype B5 was isolated in 2001 and in 2002, echovirus serotypes 2, 3, 6, 7, 9, 13, 25, 30 were isolated in 70 cases while coxsackievirus serotypes B3 and B4 were isolated in 10 cases. Various specimens tended to emerge over the years. The occurrence in 2000 tended to be mostly focus during the cold months, December through January, while in 2001, it occurred in May. In 2002, occurrence was found to be distributed from April to November with the highest rate during June and July. The strains of Vero and HEp-2 of echovirus and coxsackievirus, respectively, are highly infectious. Electron micrograph of echovirus and coxsackievirus show that they are small nonenevolped, isometric-shaped viruses. Isolated RNA from strains of echovirus and coxsackievirus showing cytopathic effects were used to undergo nested PCR which resulted in a 436 bp single band in all the strains. The serotype was sent to the Department of Virology at the Korean National Institute of Health for identification.
