To develop the functional pear fruitlet product, we prepared dried pear fruitlet and fermented pear fruitlet, respectively. Then we investigated their general characteristics, and viable cell number changes during the storage at room temperature. We also determined preference for their tastes. Dried pear fruitlet contained more ash and crude proteins as well as minerals than fermented pear fruitlet. However fermented pear fruitlet contained higher amount of edible fiber than dried pear fruitlet. Fungi were not detected from dried pear fruitlet during the storage experiment at room temperature. Numbers of bacteria from dried pear fruitlet were increased from 1.1☓105/g at the beginning to2.6☓106/g at the last day of experiment. When we determined change of fungi number during the storage of fermented pear fruitlet, we cannot detect fungi at the beginning but we detected 4.4☓102/g of fungi at the last day of storage experiment. Bacteria from fermented pear fruitlet were detected at around 1.0☓109/g during the storage periods. Preference for fermented pear fruitlet was superior to dried one.

Changes of Calbindin D-28k- and c-fos-immunoreactivities in the superior collicuclus after Eye Enucleation. Objective and methods: Calcium-binding proteins (CBPs) play an important role in the protection, differentiation and reorganization of the central nervous system. The effects of neonatal retinal deafferentation on a CBPs, calbindin D-28k were examined immunohistochemically in the superficial layer of the rat superior colliculus. Also early gene familly c-fos was examined to evaluate the neuronal characteristics in the superior colliculus after monocular enucleation. Results: On the experimental side of superior colliculus, the number of calbindin D-28k-immunoreactive (IR) cells was reduced (77.4% compared to control), but not fibers. Appearance of c-fos-like immunoreactivity was represented much more in the ipsilateral superior colliculus than contralateral side within 24h after eye enucleation. Conclusion: These results suggest that the changes of retinotectal projection may alter the expressional pattern of calbindin D-28k and c-fos expression.

국제 무역시대의 도래로 항만 물동량이 크게 증가함에 따라 항만시설의 확충이 시급한 실정이다. 비교적 양호한 지반에서의 항만공사는 종래에 대부분 행해졌으며, 현재는 아주 연약한 지반에서의 해안매립을 통한 부지조성 등의 대규모 공사가 진행중이다. 연약지반 성토시 하부지반은 압밀침하와 전단변형이 동시에 발생하므로, 양자를 고려한 안정성 판단이 매우 중요하다. 본 연구에서는 현장에서 파괴가 발생한 부산 신항만공사의 서방파제 계측결과를 분석하고 수치해석을 수행하여, 면적비 안정관리기법을 제안하였다.

Narcolepsy is a sleep disorder characterized by excessive daytime sleepiness, cataplexy, sleep paralysis, hypnagogic hallucinations and disrupted nocturnal sleep. We report a patient with a diagnosis of schizophrenia who was subsequently diagnosed as narcolepsy. A case of a 22-year-old woman with concomitant narcolepsy and psychotic symptoms was discussed from a perspective of the diagnosis and therapeutic challenges, particularly on pharmcological treatment dealing with issues raised by their coexistence.
골반염증성 질환과 질염을 가진 환자의 진단과 추적관찰에서 Chlamydia trachomatis의 검출을 위한 이중 중합효소 연쇄반응의 적용

Objectives : PCR has generally been more sensitive than the conventional microbiological test for the detection of C.trachomatis which has been a leading cause of sexually transmitted disease. The purpose of this study was to evaluate the prevalence of C.trachomatis infection in the patients with pelvic imflammatory disease(PID) and the usefulness of nested PCR as a follow-up test in patiens with C. trachomatis infection after administration of antibiotics. Methods: Cervical swab specimens were obtained from 187 patients with PID and vaginitis attending the Soonchunhyang Chunan Hospital. From the C. trachomatis positive patients, cervical swab specimens were obtained once a week after treatment until PCR tested negative. We performed the nested PCR with Chlamydia-CR kit(Bioneer, Korea.) Results: From 6(5.8%) of 187 cervical swab specimen, C. Trachomatis was detected by nested PCR. These patients were treated with doxycycline and metronidazole for 7 to 14 days. All of 6 C. trachomatis positive patients revealed PCR-negative immediately after the completion of antibiotics treatment. Conclusions: With the above results, the nested PCR is a relatively simple, fast, and practical tool for the detection of C. trachmatis and may be a useful follow-up test for monitoring the treatment effect.

Purpose : Several panoramic indices have been suggested to assess bone quality from the morphology and width of mandibular cortex on panoramic radiography. The purpose of this study was to compare dental implant failure group with control group in panoramic mandibular index (PMI), mandibular cortical index (MCI), and gonion index (GI) and to determine the effect of these panoramic indices on dental implant failure. Materials and Methods : A case-control study was designed. Test group (n = 42) consisted of the patients who had their implants extracted because of peri-implantitis. Control group (n = 139) consisted of the patients who retained their implants over one year without any pathologic changes and had been followed up periodically. They had dental implants installed in their mandibles without bone augmentation surgery from 1991 to 2001. The following measures were collected for each patients: 1) PMI, MCI, and GI were measured twice at one-week interval on preoperative panoramic views; and 2) age, sex, implant length, implant type, installed location, occluding dentition state, and complication were investigated from the chart record. Results : The PMI showed moderate level of repeatability. The intra-observer agreement of MCI and GI were good. There was statistically significant difference in PMI between two groups. There were significant different patterns of distribution of MCI and GI between two groups. Among the panoramic indices, PMI and MCI showed significant correlation with dental implant failure. Conclusion : Panoramic indices can be used as reference data in estimating bone quality of edentulous patients who are to have implants installed in their mandibles.
내경동맥의 후하방동맥류 수술시 Ring Clip의 이용 : Report of Five Cases
배시현,김철진,이정청 대한신경외과학회 1993 Journal of Korean neurosurgical society Vol.22 No.12
The development of more appropriate shapes of aneurysm clips will hopefully enable excellent clipping of most types of difficult aneurysms. The clipping of internal carotid artery(ICA) aneurysms protruding inferiorly is relatively difficult and has the high risk of premature rupture during operation using conventional clips. We report five cases of ICA aneurysms protruding inferiorly in the operative field. All aneurysms were successfully clipped with ring clips without difficulty. Our results suggest that the ring clips rather than conventional clips were appropriate in the ICA aneurysm protruding inferiorly in the operative field.

To try optimal test for the anaerobic performance of 1㎞ time trial cyclists, this study was performed by the analysis of results with the repeated test of exiting method. Seven elite male 1㎞ time trial cyclists with between 4 and 10 years of competitive riding experience participated in the study. 1. Only increasing value of CPK activity after Supramaximal exercise test was negative correlated to the 1㎞ time trial performance in variables related to the anaerobic performance, and there are on variables could estimate the 1㎞ time trial performance. 2. In general, variables related to the anaerobic performance of Supramaximal exercise test showed a significant correlation with variables of the Wingate anaerobic test, and mean power output and peak power output of the Wingate anaerobic test,and mean power output and peak power output of the Wingate anaerobic test showed a significant correlation with isokinetic power of knee joint. 3. Exercise intensity of pretest on the basis of lactate threshold has problems in the anaerobic glycolysis power test. this finding the consideration to upgrade a exercise intensity of pretest. 4. In comparison of peak value of blood lactate concentration, peak value of Supramaximal exercise test showed the highest value, but peak value of anaerobic glycolysis power test showed the lowest value. On the basis of the results obtained in this study, it is a difficult that existing anaerobic tests have a direct application to the estimation of 1㎞ time trial cycling performance. but we can find that apply these tests to the assessment of a potential capacity of 1㎞ time trial cycling performance. The exercise intensity and duration of these existing tests must be reconsiderated for a suggestion of accurate anaerobic performance test.
