        저칼슘식이가 백서의 하악골 골절치유에 미치는 영향에 관한 실험적 연구

        이상훈,황의환,이상래,LEE Sang-Hoon,HWANG Eui-Hwan,LEE Sang-Rae 대한영상치의학회 1997 Imaging Science in Dentistry Vol.27 No.1

        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.

        이상훈,이현종,백용현,김수영,박재경,홍승재,양형인,김건식,이재동,최도영,이두익,이윤호,Lee, Sang-hoon,Lee, Hyun-jong,Baek, Yong-hyeon,Kim, Su-young,Park, Jae-kyung,Hong, Seung-jae,Yang, Hyung-in,Kim, Keon-sik,Lee, Jae-dong,Choi, Do-young,L 대한침구의학회 2003 대한침구의학회지 Vol.20 No.2

        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.

        이상훈,최훈,김정구,문신용,이진용,장윤석,Lee, Sang-Hoon,Choi, Hoon,Kim, Jung-Gu,Moon, Shin-Yong,Lee, Jin-Yong,Chang, Yoon-Seok 대한생식의학회 1987 Clinical and Experimental Reproductive Medicine Vol.14 No.2

        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.

        단기 호르몬 병합 치료가 폐경 후 우울증 환자의 인지 기능에 미치는 영향

        이상훈,고영훈,조숙행,정인과,김승현,이문수,Lee, Sang Hoon,Ko, Young-Hoon,Joe, Sook-Haeng,Jung, In-Kwa,Kim, Seung-Hyun,Lee, Moon-Soo 대한생물정신의학회 2005 생물정신의학 Vol.12 No.2

        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.

        이상훈,이창섭,이한구,김석준,Lee, Sang-Hoon,Lee, Chang-Seop,Lee, Han-Koo,Kim, Sug-Jun 대한근골격종양학회 1995 대한골관절종양학회지 Vol.1 No.1

        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.

        β-Glucan 추출에 미치는 온도, 용매 농도 및 pH의 영향

        이상훈,장귀영,김기종,이미자,김태집,이준수,정헌상,Lee, Sang Hoon,Jang, Gwi Yeong,Kim, Kee Jong,Lee, Mi Ja,Kim, Tae Jip,Lee, Junsoo,Jeong, Heon Sang 한국식품영양학회 2012 韓國食品營養學會誌 Vol.25 No.4

        추출조건에 따른 귀리겨 ${\beta}$-glucan의 추출조건을 확립하기 위하여 추출온도($40{\sim}60^{\circ}C$), 추출용매의 에탄올 농도(0~20%) 및 pH(5~9)를 변수로 중심합성계획법으로 설계하여 ${\beta}$-glucan 추출특성을 조사하였다. 추출시간의 증가에 따라 ${\beta}$-glucan의 추출속도는 추출초기에 급격히 증가하였으나, 이후에는 완만하였다. 총괄물질전달계수는 $3.363{\sim}8.552{\times}10^{-6}cm/min$ 범위로 낮은 추출온도에서는 추출용매의 농도가 낮을수록, 높은 추출온도에서는 추출용매의 농도가 높을수록 증가하였지만 pH에 의한 영향은 적은 것으로 나타났다. 추출용매의 pH는 중성일 때보다 산성이나 알칼리성일 때 ${\beta}$-glucan의 추출량이 증가하였다. 추출조건에 따라서 ${\beta}$-glucan 수용액의 점도는 유의적인 차이를 보였으며, 총괄물질전달계수가 높을수록 crude ${\beta}$-glucan 수용액의 점도가 높게 나타났으며, 점도, 추출율 및 총괄물질전달계수의 상관관계를 분석한 결과, 각각의 요인들이 높은 양의 상관관계(p<0.01)를 나타내었다. This study investigated the effects of temperature, solvent concentration, and pH on the ${\beta}$-glucan extraction. Oat bran ${\beta}$-glucan was extracted with different extraction conditions, using various combinations of experiment factors, such as temperature (40, 45, 50, 55, and $60^{\circ}C$), ethanol concentration (0, 5, 10, 15, and 20%), and pH (5, 6, 7, 8, and 9). Under the various extraction conditions, ${\beta}$-glucan extraction rate and overall mass transfer coefficient of oat bran ${\beta}$-glucan, and viscosity of oat bran extracts were investigated. As increasing the extraction time, the extraction rate of ${\beta}$-glucan increased. The overall mass transfer coefficient of ${\beta}$-glucan ranged from $3.36{\times}10^{-6}$ to $8.55{\times}10^{-6}cm/min$, indicating the lowest at the extraction condition of $45^{\circ}C$, 15% and pH 8, and the highest at $50^{\circ}C$, 0% and pH 7. It was significantly greater with increasing extraction temperature and decreasing ethanol concentrations of extraction solvent, except for solvent pH. There were positive correlations among the overall mass transfer coefficient, the extraction rate of ${\beta}$-glucan, and the viscosity of extract.

        오차드그래스 성숙종자로부터 캘러스 유도 및 고효율 식물체 재분화

        이상훈,이동기,김진수,이병현,Lee, Sang-Hoon,Lee, Dong-Gi,Kim, Jin-Soo,Lee, Byung-Hyun 한국식물생명공학회 2003 식물생명공학회지 Vol.30 No.4

        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.
