Purpose:We investigated the effect of menopausal duration on cognitive function using adjunctive hormone replacement therapy(HRT) in postmenopausal women with depression. Method:Twelve postmenopausal women with depressive disorder were enrolled. Six patients having menopausal duration of less than 3 years was assigned to the short duration group and six patients of more than 3 years to the long duration group. Each patient was treated with conjugated equine estrogen(1.25mg) plus medroxyprogesterone(5mg) for 8 weeks. Cognitive performance was measured by the Verbal Memory Test, Visual Memory Test, Trail Making Test, Digit Symbol Test, and Attention Shift Test. The Beck Depression Inventory was used for evaluation of depressed mood. The reproductive hormone levels were also measured. Results:The long duration group showed the lower performance only in Trail Making Test B compared with the short duration group at baseline. After 8 weeks, the long duration group performed significantly better in the Trail Making Test B compared with the short duration group. The differences in change of depressive mood and gonadal hormone level between two groups were not significant. Conclusion:Menopausal duration before HRT may influence the effect of estrogen on cognition in some cognitive domains. This might be related with estrogen receptor hypersensitivity which induced by the longer estrogen deficiency.

Objective: To evaluate the effects of bee venom acupuncture(BVA) on the rehabilitation and quality of life in rheumatoid arthritis(RA) patients Methods: Patients with RA were treated with the BVA therapy twice a week for 3 months. Tender joint counts, swollen joint counts, morning stiffness, Erythrocyte Sedimentation Rate(ESR), C-reactive protein(CRP), patient global assessment, physician global assessment, Korean health assessment questionnaire(KHAQ) were estimated and analyzed before and after BVA therapy. Results: Tender joint counts, swollen joint counts, morning stiffness showed significant decrease after BVA therapy. But, as acute inflammatory reactants, ESR showed no significant difference and CRP showed significant increase after BVA therapy. Patient global assessment, physician global assessment, and KHAQ index showed significant improvement after BVA therapy. Conclusions: BVA therapy can improve rehabilitation and health-related quality of life in RA patients as well as clinical symptoms and signs. Further study is required in more population with large scale including acute inflammatory reaction of BVA therapy.

In an effort to optimize tissue culture conditions for genetic transformation of orchardgrass (Dactylis glomerata L.), an efficient and high-frequency plant regeneration system from seed-derived calli was established. Embryogenic calli induced on MS medium containing 3mg/L 2,4-D and 0.1mg/L BA had significantly improved regeneration ability. Plant regeneration rate was 92% when embryogenic calli were cultured on N6 medium supplemented with 1mg/L 2,4-D and 3mg/L BA. Among three kinds of medium, MS and N6 medium were optimal for embryogenic callus induction and plant regeneration, respectively. Ho difference in callus induction frequency was observed among four cultivars of orchardgrass, however, "Roughrider" cultivar showed higher regenerability with the frequency of 61%. Addition of maltose to the regeneration medium as a carbon source dramatically increased regeneration frequency up to 69%. A short tissue culture period and high-frequency regeneration system would be beneficial for molecular breeding of orchardgrass through genetic transformation.

국립암센터에 설치된 양성자 치료기는 양성자 가속기의 운영을 통해 많은 양의 이차방사선을 방출하게 되는데, 이는 양성자 빔이 가속 중에 주위의 물질과 반응을 하여 이차 입자를 발생하고 방사성 동위원소도 생성하기 때문이다. 생성된 방사성 동위원소에 의한 방사선량은 시간에 따라 감쇠되지만 양성자 치료기의 운영 및 유지보수를 위해 수시로 가속기 작업종사자들이 시설내부로 접근해야 하며 이로 인해 이차방사선에 의한 피폭 문제가 발생될 수 있다. 본 논문에서는 양성자 가속기(Cyclotron)를 포함한 양성자 치료기의 운영을 위해 필요한 작업종사자들의 작업환경을 평가하고, 적절한 수준의 방사선 방호대책을 수립하기 위해 양성자 치료기 운영 중 가장 높은 수준의 방사선이 발생되는 양성자 가속기(Cyclotron) 및 주변 지역에서의 가속기 가동에 따른 방사선 발생 정도를 측정하였고 그 지속시간을 분석하였다. 이를 위해 양성자 빔의 손실이 가장 큰 가속기 주변과 에너지 선택 시스템(Energy Selection System, ESS)지역의 탄소(graphite, $^{12}C$) 재질로 구성된 에너지 감쇠장치(degrader)에서의 방사선 변화를 추적하고, 가속기에서 생산된 230 MeV의 고정된 에너지 빔이 에너지 감쇠장치(degrader)를 거쳐 ESS를 통해 전송된 빔의 효율을 산출하고 빔의 전송 구간에서의 상대적인 방사화 정도를 분석하였다. 이러한 분석 자료를 토대로 작업종사자들의 작업간 피폭 수준을 계산하고 연간 피폭 정도를 측정하였다. 작업 중 가속기 시설내의 선량은 수십 ${\mu}Sv/h$로 다른 방사선 치료기에 비해 상대적으로 높은 수준이지만 작업시간을 고려한 연간 총 피폭 선량은 작업자에 따라 1~3 mSv/year 정도로, 연간 피폭 한계 선량보다 충분히 낮은 수준으로 운영이 가능하였다. Proton therapy facility, which is recently installed at National Cancer Center in Korea, generally produces a large amount of radiation near cyclotron due to the secondary particles and radioisotopes caused by collision between proton and nearby materials during the acceleration. Although the level of radiation by radioisotope decreases in length of time, radiation exposure problem still exists since workers are easily exposed by a low level of radiation for a long time due to their job assignment for maintenance or repair of the proton facility. In this paper, the working environment near cyclotron, where the highest radiation exposure is expected, was studied by measuring the degree of radiation and its duration for an appropriate level of protective action guide. To do this, we measured the radiation change in the graphite based energy degrader, the efficiency of transmitted beam and relative activation degree of the transmission beam line. The results showed that while the level of radiation exposure around cyclotron and beam line during the operation is much higher than the other radiation therapy facilities, the radiation exposure rate per year is under the limit recommended by the law showing 1~3 mSv/year.

The prognosis of parosteal osteosarcoma is better than any other malignant bone tumors, but there are many controversies in its treatment. We tried to evaluate the prognosis and the effectiveness of limb-salvage operation in the treatment of the parosteal osteosarcoma. We experienced 12 patients of conventional parosteal osteosarcoma(2 males and 10 females) from 1981 to 1991. The limb-salvage operations with wide resection margin were done in 8 patients(5 tumer prosthesis, 2 resection arthrodesis and 1 vascularized fibular transplantation), marginal en-bloc resection and amputation in 2 patients, respectively. The duration of mean follow up was 5 years and 9 months, ranging from 2 year-3 months to 11 years, except of the patient who died with metastasis 1 year 8 months after. The disease-free survival rate(DFSR) of all patients was 68% and that of the patients treated with limb-salvage operation was 88% at 7 years. The DFSR was 33% with marginal margin(3 cases) and 89% with wide margin(9 cases) at 7 years. The results were unsatisfactory in the conventional parosteal osteosarcoma treated with marginal resection. The limb-salvage operation with wide surgical margin was thought to be the treatment of choice.

Objective : In order to study the effects of bee venom(BV) on the pain, edema, and acute inflammatory reactant of rheumatoid arthritis(RA) patients. Methods : Patients with RA who met the ACR(American College of Rheumatology) 1987 revised criteria for the diagnosis of RA were treated with the BV therapy twice a week for 3 months. Tender joint counts, swollen joint counts, Visual analog scale(VAS), morning in stiffness, ESR, C-reactive protein(CRP) were analyzed before and after BV therapy. Results : The results as follows: 1. Tender joint counts in patients after BV therapy were significantly lower than those before BV therapy($9.0{\pm}7.9$ vs $15{\pm}11.4$, p=0.002). 2. Swollen joint counts of the patients after BV therapy were significantly lower than those before BV therapy ($5.0{\pm}6.1$ vs $1.5{\pm}2.3$, p=0.001). 3. VAS in patients after BV therapy was significantly lower than before BV therapy($60.8{\pm}17.6$ vs $38.0{\pm}15.9$, p=0.000). 4. Duration of morning stiffness in patients after BV therapy was significantly reduced compared with that before BV therapy($119.1{\pm}112.6min$ vs $59.0{\pm}89.7min$, p=0.009). 5. ESR and CRP were not significantly changed before and after BV therapy, suggesting BV itself could make inflammatory reaction as well as therapeutic effect. Conclusions: BV therapy improved tender joint counts, swollen joint counts and duration of morning stiffness in this study, and further study is needed in log-term effect of BV therapy.

Ninety-one patients with irreparable tubal disease underwent in Vitro Fertilization-Embryo Transfer (IVF-ET) in Seoul National University Hospital. Ovulation was stimulated in 104 cycles by human menopausal gonadotropin (HMG) or follicular stimulating hormone (FSH)/human chorionic gonadotropin (HCG). The patients were classified as high (>900 pg/ml), intermediate (400-900 pg/ml), or low (<400pg/ml) responder according to preovulatory $E_2$ response and four $E_2$ patterns were found. The overall pregnancy rate per cycle in this consecutive series was 11.5% (n=12). The number of preovulatory oocytes per cycle was higher significantly in intermediate and high responder group than in low responder group (P<0.01), While the number of immature oocytes per cycle significantly higher in low responder group than high and intermediate responder group (P<0.01). The pregnancy rate in each responder group was not signigicant. According to the $E_2$ pattern of response, there was no significant difference in number of the immature and preovulatory oocytes recovery per cycle. There was a apparently direct relationship between the preovulatory $E_2$ pattern and pre gnancy rate was noted.

위암과 관련된 급성 파종성 혈관 내 응고증의 발병 빈도는 0.68%로 보고되고 있으며 생존 기간은 $1{\sim}3$주로써 예후가 매우 불량하다. 본 증례는 47세된 여자가 호흡곤란과 질출혈을 주소로 내원하여 위암4기(골 및 골수전이)로 진단됨과 동시에 검사실 소견상 급성 파종성 혈관 내 응고증 소견을 보인 예이다. 현재 위암과 동반된 급성 파종성 혈관 내 응고증에 대한 표준 복합 항암화학요법 약제는 정립되어 있지 않다. 본 예에서는 irinotecan과 cisplatin 복합화학요법을 시행하여 환자의 증상 및 급성 파종성 혈관 내 응고증 소견이 호전되고 생존기간이 연장된 1예를 보고하는 바이다. 따라서 위암과 동반된 급성 파종성 혈관 내 응고증의 경우에는 혈액학적으로 불안정하더라도 대한 전신 항암화학요법을 시행함으로써 생존기간을 연장하고 환자의 삶의 질을 향상시킬 수 있다. Acute disseminated intravascular coagulation (DIC) associated with gastric cancer is not common and has short survival of 1 to 3 weeks. Systemic chemotherapy in spite of hematologic unstability for gastric cancer may prolong survival time. A 47-year-old woman who complained of dyspnea, vaginal bleeding and easy bruisibility was diagnosed to stage IV gastric cancer with acute disseminated intravascular coagulation based on the laboratory data. She also had multiple bone metastases and bone marrow involvement. This is the first case treated with combination chemotherapy of irinotecan and cisplatin for advanced gastric cancer complicated by disseminated intravascular coagulation at the time of diagnosis, With systemic chemotherapy, some of the bleeding symptoms and the DIC process improved, even not completely recovered. However the patient died of disease progression and survival time was 12 weeks.

The purpose of this study was to investigate effects of osteoporosis on fracture wound healing in the calcium deficient rat. To research the experiment some ten-week old Wistar strain rats with approximately 300 gms weight were selected. Then, the rats were divided into two groups: Normal diet group(rats given a normal diet before and after bone fracture) and Low calcium diet group(rats given a low calcium diet before and after bone fracture). Both groups had been provided with each diet for three weeks. When the rats became thirteen weeks old, the mandibular angle of rats in both groups was artificially fractured for test. The healing of fracture wounds was reviewed by using soft x-ray radiography and /sup 99m/Tc-MDP bone scan and also histopathologic examination. The obtained results were as follows : 1. The radiolucency of the fracture site for the Normal diet group started to decrease from the 14th day since the experiment was made, while the Low calcium diet group began decrease in the radiolucency from the 21st day of the experiment. The radiolucency for the Normal diet group disappeared at the 42nd day, but one for the Low calcium diet group disappeared at the 56th day of the experiment. 2. The highest uptake rate of /sup 99m/Tc-MDP stood at the 14th day of the experiment in the Normal diet group and the Low calcium diet group's maximum rate was recorded at the 21st day of the experiment. These both groups were gradually experiencing decrease in the uptake rate as the experiment time was going on. However, the uptake rate in the Low calcium diet group was lower than one in the Normal diet group. 3. For the Normal diet group, the newly formed trabeculae, which were similar to one of the surroundung bone, were seen at the 42nd day of the experiment. On the other hand, the Low calcium diet group showed at the 56th day of the experiment that the osteoporotic findings looked weak, irregular trabeculae, and also large bone marrow space were observed clearly. As a result of the above experiment, it is said that the healing of the fracture can be completed for both groups, the Normal diet group and the Low calcium diet group. However, the amount of the newly formed bone wound in the Low calcium diet group is rather decreased compared to one in the Normal diet group and at the same time the healing of the fracture is delayed in the Low calcium diet group. Consequently, for the successful healing of fracture in osteoporosis, it is considered that the management of the etiologic factors of osteoporosis must be preceded. The more study of calcium metabolism and functions of osteoblast and osteoclast needs to proceed on.
