Steroid cell tumor is a rare ovarian sex cord-stromal tumor which accounts for 0.1% of all ovarian tumors. Until now, only 4 cases have been reported in domestic literatures. Steroid cell tumor often secrets testosterone and presents virilization in adult women or precocious puberty in children. Treatment is often performed by surgical removal, adjuvant chemotherapy and radiation, but completely accepted treatment was not existed. We experienced a case of steroid cell tumor, which was manifested by typical virilization in a 43-year old patient, who was previously performed hysterectomy and unilateral oophorectomy. So, we present with a brief review of the literatures.

대구시와 경산시의 하수에서 음이온계 합성세제인 sodium dodecyl sulfate(SDS)와 sodium dodecylbenzene sulfonate(SDBS)를 유일한 탄소원으로 이용하는 균주 289종을 분리하고 이중 합성세제 분해력이 강한, 그람음성 간균으로 운동성인 8균주를 선정하여 그 선정균들의 특성을 조사하였다. 선정균은 40℃ 이상에서는 생육하지 못하였으며 생육 최적 pH는 균주간에 다소 차이가 있었으며 pH 4.0 이하에서는 선정균 모두 생육치 못하였다. 질소원으로는 SDS분해균의 생육에는 potassium nitrate가, SDBS 분해균의 생육에는 soytone이 좋았다. SDS 분해균인 DS-3, 6, 8, 24 및 SDBS 분해균인 BS-7, 8은 세제농도가 5.0% 이상에서도 생육이 가능하였다. 선정균들은 tetracycline에 감수성이 강한 것으로 나타났지만 penicillin에는 강한 내성을 띠는 것으로 나타났고, ??와 ??금속이온은 모든 선정균들의 생육을 억제하는 것으로 나타났다. On purpose to isolate the organisms, which would utilize detergents(sodium dodecyl sulfate, SDS and sodium dodecylbenzene sulfonate, SDBS) as a sole carbon source, from the waste water of Kyungsan and Taegu city 289 strains were isolated. Among them 8 strains, which are gram negative rods with motility and produce strong enzyme to biodegrade the synthetic detergents, were selected. The characteristics of them were investigated as follows, 8 strains were failed to grow above the temperature of 40℃ and below the pH 4.0 even though they have variable optimum pH. Potassium nitrate was very effective for the growth of SDS-biodegradable strains and soytone was effective for the growth of SDBS-biodegradable strains as a sole nitrogen source. Among 8 strains especially DS-3, DS-6, DS-8 and DS-24(SDS-biodegradation strains) and BS-7 and BS-8(SDBS-biodegradation strains) could grow above 5.0% of detergent concentration. All of 8 strains were very sensitive to tetracycline but resistant to penicillin. Selected 8 strains were inhibited by metal ions of ??(0.156mg/㎖) and ??(0.156mg/㎖).

Conventional CT-guided needle localization has been reported many times, but a few reports of interventional procedures by using multidetector CT scan with CT-fluoroscopy have been described. We presented 36 cases of CT-fluoroscopy guided interventional procedures focusing on the puncture technique. Two cases of small pneumothorax and one case of pulmonary hemorrhage out of 2lcases after lung biopsy, were not needed any treatments We can easily and accurately access to the lesion by using CT-fluoroscopy and unique our marker system.

Objectives : The present study investigated the brain regions that correlate with ambivalence in schizotypy, a latent personality organization that is proposed to precede and contribute to the liability of developing schizophrenia. Methods : Using ^(18)F-FDG PET scan, we investigated the brain activity of twenty one normal healthy subjects during the resting state. Questionnaires, including the Korean Version of Schizotypal Ambivalence Scale (K-SAS), were administrated after the scan in order to assess the self-rated individual differences in ambivalence. Results : The Schizotypal Ambivalence Scale (SAS) scores showed positive correlation with the metabolic rates in the left parahippocampal gyrus and the fornix. In contrast, the Ambivalence over Expression of Emotion Questionnaire (AEQ) scores showed negative correlation with the metabolic rates in the right putamen. Although scores of the two ambivalence scales Correlated positively (Pearson correlation coefficient 0.477, p<0.050), there was no substantial overlap between the neural correlates. Conclusion : This study suggests that the hippocampal complex, which dysfunction has been reported to correlate with impaired information processing in schizophrenia, may underlie schizotypal ambivalence.

치커리와 쑥갓에 있어 식물조직배양이나 형질전환 과정에 필요한 무균 절편체를 얻기 위한 적절한 방법을 제안하기 위해 기내 파종을 위한 소독조건과 배지조성 및 종류에 관한 실험들이 실시되었다. 치커리 'Precole'은 10% NaOCl, 15분간, 'Chiavari'는 5% NaOCl, 15분간이 기내파종 시 발아 및 자엽전개를 촉진시키고 오염발생을 억제하는 조건으로 선발되었다. 쑥갓에서는 발아 및 자엽전개율에 있어 NaOCl 처리 간에 차이는 없었지만 10% NaOCl, 30분간 처리에서 가장 낮은 오염율이 관측되었다. 치커리와 쑥갓의 발아와 자엽전개율 모두 인조토양배지의 사용으로 MS 배지에 비해 현저히 향상 되었다. 비록 육안으로는 오염여부를 관측할 수는 없었지만 이들 인조토양배지에서 자란 쑥갓 묘의 자엽을 MS배지에 치상하여 배양 시에는 오염증상이 나타났으며 이들을 NaOCl 1%로 15분간 소독 후 치상한 결과 오염율을 현저히 낮출 수 있었다. Experiments on the sterilization condition and medium composition and type for in vitro sowing were conducted to suggest a proper way to produce enough aseptic explants for tissue culture or transformation study in chicory and garland chrysanthemum. Fifteen minutes soaking treatment with 10% NaOCl for chicory 'Precole' and 15 minutes with 5% NaOCl for chicory 'Chiavari' were selected as proper sterilization conditions to promote in vitro germination and cotyledon expansion and inhibit the seedling contamination from seed itself. In garland chrysanthemum, there was no significant difference in germination and cotyledon expansion ratio among NaOCl treatments, but the lowest seedling contamination ratio was observed by 30 minutes soaking with 10% NaOCl. Both germination and cotyledon expansion ratio in chicory and garland chrysanthemum were significantly increased by using the artificial soil media in contrast to MS media. Although seedling contamination with the artificial soil media could not be observed with bare eyes, cotyledon explants harvested from the plants grown on the media showed some fungal growth when they were placed onto MS media for further culture. However the percentage of the contamination from these explants was dramatically decreased by 15 minutes sterilization with 1% NaOCl.

The use of MRI to study CSF flow in the brain was mainly by flow void signal on T2WI or hydrodynamic study with phase-contrast cine MRI. Authors pay attention to high signal intensity in CSF passway on fast FLAIR MR image of the brain, usually known as the artifact. The conclusions are as below; 1. The high signal intensity appeared in CSF passway on fast FLAIR MR image of the brain near constantly. 2. The high signal intensity was best visualized on image perpendicular to the CSF flow. 3. The high signal intensity was related to the velocity of the fluid not to the direction of the fluid.

When VCR is operated in the deck, tape navigates from S-Reel Table to T-Reel Table through the several posts and head drum. During the navigation, the position of tape is influenced by the several factors. And the variant of the position becomes the cause of unstable system. Through this study, we will find the factors which gives the big influenced in this system. And we will find the factors which should be mainly controlled in the VCR deck assembly. For the study, we will use the Multiple Linear regression analysis.

Idiopathic thrombocytopenic purpura(ITP) is an autoimmune bleeding disorder characterized by the development of antibodies to one's own platelets, which are then destroyed by phagocytosis in the spleen and liver. Its clinical manifestations are characterized by bleeding and the most serious complication is hemorrhage into the central nervous system, but which is rarely seen below 1%. In treating IPT, the therapy of first chice is administration of adrenocorticosteroid and r-globuline. If satisfactory results are not obtained, then splenectomy is recommended. If this also proves inadequate, then administration of immunosuppressants is carried out. 16-year-old male was admitted with complaints of left hemiplegia and nasal bleeding. This case may be developed spontaneous intracerebral hemorrhage causing thrombocytopenia and was treated by steroid, r-globuline and splenectomy, but satisfactory results are not obtained. After all, the paient was successfully treated with cyclophosphamide.
