This study was designed to clarify histologic changes in the experimental rabbit kidney and ureter after unilateral partial or complete ureteral obstruction. A total of 20 adult white rabbits were divided into 4 subgroups in the partial obstruction followed by 2 weeks, the partial obstruction followed by 4 weeks, the complete obstruction followed by 2 weeks, and the complete obstruction followed by 4 weeks. The normal control group was consisted of 5 adult white rabbits. The kidneys and ureters for light microscopy were fixed in 10% neutral formalin, embedded in paraffin and stained with hematoxylin and eosin. Abnormal histologic fingings showed in ipsilateral kidney and ureter of all subgroups(such as dilatation of uriniferous tubule, focal necrosis and desquamation of epithelium, interstitial fibrosis, glomerular congestion, widening of Bowman's space, dilatation of ureter, epithelial cell atrophy or loss, interstitial fibrosis and interstitial inflammation). These findings were most severe in the group of the complete-obstructed ureter for 4 weeks. No significant changes showed in contralateral ureter of all subgroups. The degree of obstruction was severe and period of obstruction was long, the histological changes in ipsilateral side were severe. Despite of changes in ipsilateral side no abnormal findings showed in contralateral side. We suggest that long term experimental investigation of histologic changes in ipsilateral side and compensatory changes in contralateral side have to be studied.

목적: in vivo 및 vitro에서 해마 신경세포의 발생단계별 NMDA 수용체 아단위 mRNA 발현에 대한 연 폭로 영향을 알아보고자 하였다. 방법: 흰쥐 해마 신경세포의 발생단계별 NMDA 수용체 NR2A, NR2B 아단위 mRNA 발현에 대한 연의 영향은 정상군과 연 폭로군의 출생 후 7일, 14일, 22일 흰쥐의 해마에서 in situ hybridization으로 mRNA 발현 정도를 densitometer로 측정하여 비교하였고, 연과 NMDA 의 세포독성은 해마 신경세포 일차배양 후 도립현미경을 이용한 형태학적인 관찰과 LDH 활성도를 이용하여 측정하였다. 결과: 연 과 NMDA 에 의한 세포독성에 대한 in vitro 실험에서 형태학적 소견과 LDH 활성도에서 해마 미성숙 신경세포와 성숙 신경세포사이의 차이가 있었으므로, 연과 NMDA 독성효과는 해마 신경세포의 발달 단계에 따라 차이가 있다. 정상군의 해마에서의 NR2A mRNA 발현은 출생 후 연령이 증가함에 따라 점진적으로 증가하였으나, NR2B mRNA 발현은 출생 후 연령이 증가함에 따라 점진적으로 증가하였으나 NR2B mRNA 발현은 연령의 증가에 따른 변화가 없었다. 연 폭로에 희한 NR2A mRNA 발현은 유의하게 감소하였으나(p<0.05), NR2B mRNA 발현은 변화가 나타나지 않았다. 만성적 연 폭로는 NR2A를 포함하는 NMDA 수용체를 감소시킬 수 있음을 알 수 있다. 결론: 연은 해마신경세포의 발생단계에서 NMDA 수용체 아단위 특히 NR2A mRNA 발현의 변화를 야기하여 시냅스 신호 전달에 영향을 나타냄을 알 수 있었다.

Malignant peritoneal mesothelioma is a rare neoplasm that arises from the mesothelium of a serosal cavity and is a rapidly fatal disease with a median survival of 4 to 12 months for untreated cases. Recently, we experienced a case with malignant peritoneal mesothelioma who was suspected hepatocelluar carcioma by abdominal CT scan and was confirmed by biopsy including immunohistochemical stain(calretinin) after surgery. We performed tumor excisions and wedge resection of the liver(segment Ⅷ)and inserted Tencoff catheter in abdominal cavity at 25th day of post-operation. We treated with intraperitoneal paclitaxel(25mg/m^(2)/day for 5 days) six courses monthly. She was well tolerable and is still living without any evidence of recurrence for 14th month of post-operation.

Background: Micafungin, a potent inhibitor of 1,3-β-D-glucan synthase, is a novel antifungal agent of the echinocandin class. In vitro study showed that micafungin was effective against Aspergillus species as well as Candida species, but clinical data on the prophylactic efficacy against invasive fungal infections (IFIs) other than candidiasis are still lacking. Materials and Methods: We identified 60 consecutive adult hematopoietic stem cell transplantation (HSCT) recipients who received at least 3 doses of micafungin during neutropenic period. Micafungin was started as an alternative in patients who were intolerant or had adverse events (AEs) to primary prophylactic antifungal agents. We retrospectively reviewed the medical records and analyzed the efficacy and safety of micafungin for prophylaxis against IFIs. Results: The patients either had autologous (n=9) or allogeneic (n=51: 1 syngeneic, 24 sibling, 26 unrelated donor) HSCT. Itraconazole oral solution (n=58) was the most frequently used first line antifungal agent for prophylaxis and was administered for median 11 days. The most frequent cause of switch to micafungin was vomiting (n=42). The duration of neutropenia and micafungin administration was median 13 and 12 days, respectively. A successful outcome was achieved in 45 (75%) patients. Empirical antifungal therapy was initiated in 13 (22%) patients. There were 2 cases (3.3%) of breakthrough fungal infections which comprised a probable invasive pulmonary aspergillosis and a possible invasive fungal sinusitis. There was no case of invasive candidiasis. A total of 53 (88%) patients experienced at least one AE regardless of causality during micafungin administration. The most frequent AEs were hypokalemia, vomiting, diarrhea, and elevated serum aspartate aminotransferase or alanine aminotransferase. Among the aforementioned AEs, only 1 case of diarrhea could be classified as a probable relation with micafungin when causality was assessed. There was no AEs that caused discontinuation of micafungin. Conclusions: Micafungin seems to be a safe and effective agent for prophylaxis of IFIs including aspergillosis as well as candidiasis in HSCT recipients. However, further large, prospective, and randomized comparative studies are warranted for aspergillosis.

Although porous concrete is recently used as a pavement at a parking lot, a public square and a bicycle road, we use without enough examining. Most the maintenance of quality for porous concrete is only dealt with strength and color tone. Also, there is not yet enough fundamental data about dynamical properties for strength, rate of void and water permeability, even when it is applied to at the scene, it is been a matter. Accordingly in this study analyzed influences through the dynamical properties, combination, and time to vibration. After the analyzation, they investigated peculiar dynamics which are strength of porous concrete, rate of void, and water permeability follow the rate of increase on an admixture making pozzolan reaction. This is purpose to improve capacity of the sidewalk permeable concrete and development of the economical technique for pavement.

We evaluated the cartilage repair potential of a hyaluronic acid and fibrin mixture when transplanted into cartilage defects. Circular, articular, cartilage defects 4-mm in diameter were made in the trochlear region in 21 New Zealand white rabbits divided into three groups. The seven rabbits in the control group underwent microfracture (M group), the seven rabbits in the experimental group underwent microfracture with subsequent injection of hyaluronic acid mixed with fibrin (MH group), and seven rabbits in the other experimental group underwent microfracture followed by injection of bone marrow concentrate and hyaluronic acid mixed with fibrin (MBH group). At week 12 following surgery, the cartilage was observed and histologically compared in the three groups. The surface of the newly generated cartilage was very smooth and even, and we noticed that the entire area was completely regenerated in both experimental groups. The control group showed incomplete and irregular cartilage formation in the defect. In histologic scoring, comparison of the MBH group (M= 2.333) and the M group (M= 9.000) differed significantly (P= 0.046). Therefore, injection of a mixture of bone marrow concentrate, hyaluronic acid and fibrin to treat articular cartilage defects of the knee appears to be an effective method of cartilage regeneration.

The purpose of the present study was to examine the relationship between their problem behavioral pattern and anxious trends among Korean student adolescent. Zung's measurement of anxiety level undergone through used of the self-rating anxiety scale. the data were collected through the questionaire survey which was conducted on Dec.1, 1983. Subjects served for this atudy consisted of 1,404 syudents in Korea, randomly sampled from Korean student population by means of census method. The data were analysed by CDC-174 computer of KAIST, using SPSS pogram. Statistical methods empoyed were χ^2 test and Eta measures. the results of this study were as follows. 1. It showed that students psychological anxious trends had greatest significant correlation with adolescent student's problem brhavioral pattern, but the cardiovascular, respiratory, gastrointestional and genitourinary anxious trends has not significantly related with student's problem behavioral pattern. 2. Students group with undersocialized aggressive, undersocialized nonaggressive,undersocialized school-norm avoidant, or socialized nonaggressive behavioral patterns were less anxious, whereas those with socialized latent aggressive, socialized sexual, or socialized modellong behavioral patterns were higher anxious.
