        골다공증 환자 혈청이 정상인 조골세포의 성장과 분화에 미치는 영향

        김진,이재훈,김경욱,이광원,한상배,김환묵 대한악안면성형재건외과학회 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.4

        Osteoporosis is a condition in which an imbalance appears between bone resorption and formation, with bone resorption exceeding formation. Recent studies have shown that bone formation abnormalities in various forms of osteopenia result mainly from defective recruitment of osteoblastic cells. These abnormalities in osteoblast function and bone formation are associated with alterations in the expression or production of several growth factors, such as TGF-β which modulate the proliferation and activity of bone-forming cells. Bone transplantation is an absoulte requirement in several patholigical conditions. The growth factors, such as TGF-β, PDGF, were the effective in promoting growth of the bone in vitro and in animal models. We have investigated the effects of PDGF and TGF-β on the proliferation and differentiation of the normal human osteoblast in vitro culture. The normal human osteoblast from iliac bone were primarily cultured. The serums obtained from the osteoporotic patients and the normal was used to quantify PDGF and TGF-β from the osteoporotic patients serum and the normal serum. To clarify the effects of the various different the culture conditions such as 1×10 exp(4) cells/㎖, 2.5×10 exp(4) cells/㎖, 5×10 exp(4) cells/㎖, 10×10 exp(4) cells/㎖ (0.2∼2×10 exp(4) cells/well) of the osteoblast at 24 hours, 48 hours, 72 hours under 10% FBS, 10% normal human serum, 10% osteoporotic human serum, 3% normal human PRP, 3% osteoporotic human PRP. The cell proliferation and differentiation was determined by [^3H]-thymidine and SRB assay, and the magnitude of differentiation to osteoblast was confirmed by von Kossa staining and alkaline phosphatase stain and measuring the alkaline phosphatase activity during 48 hours and 72 hours. Statistical differences were evaluated using the scheffe's test. The ANOVA procedure of the SAS system. The obtained results were as follows ; 1. The age distribution of normal human was 36.9±4.4 old, osteoporotic human was 72.5±0.2 old with statistical significant difference(p<0.05). 2. The quantification of TGF-β of the normal human serum was 39658.38±11630.43 pg/㎖, the osteoporotic human serum was 30459.40±1704.92 pg/㎖ with statistical significant difference. The quantification of PDGF of the normal human serum was 3064.13±709.51 pg/㎖, the osteoporotic human serum was 2514.13±140.21 pg/㎖ with no statistical significant difference(p<0.05). 3. The DNA synthesis and protein assay of human osteoblast at 24 hours, 48 hours, 72 hours was similar increased to 10% normal human seurm, 10% osteoporotic human serum. There was no statistical significant difference between the normal human and the osteoporotic patients in 3% normal human PRP and 3% osteoporotic human PRP. 4. The optimal cell concentration was 5×10 exp(4) cells/㎖ among 1×10 exp(4) cells/㎖, 2.5×10 exp(4) cells/㎖, 5×10 exp(4) cells/㎖, and 10×10 exp(4) cells/㎖. The DNA synthesis was decreased after 72 hours in the normal human serum and PRP, the osteoportic serum and PRP. 5. The alkaline phosphatase activity was as the same result 10% FBS, 10% osteoportic serum and 10% normal human serum at 48 hours with no statistical significant, but the alkaline phosphatase activity was increased in 10% osteoportic human serum and 10% normal human serum except 10% FBS at 72 hours. From above result, the amount of TGF-β of the normal human growth factor was higher than the osteoporotic patients, but the growth factors of the osteoportic patients were enough the proliferation and differentiation of normal human osteoblasts such like the same effects of normal human growth factors.

        실리콘 겔에 활성화된 복강 대식세포의 interleukin-6 및 tumor necrosis factor-α에 의한 섬유모세포 중식 자극

        김환묵,한상배,이백권,이종원,한기택,천지훈 大韓成形外科學會 1998 Archives of Plastic Surgery Vol.25 No.5

        Silicone gel breast implants may induce local(fibrous capsular contracture) or systemic(rheumatoid arthritis, systemic sclerosis, etc) complications. The exact mechanism of fibrous capsular contracture has not been fully understood. In the present study, we tried to find out the effect of silicone gel on the fibroblast proliferation which has been known as a major contributing factor in fibrous capsular contracture formation. In vitro, activated macrophages are known to secrete monokines which affect fibroblast proliferation and collagen synthesis. And tumour necrosis factor-α(TNF-α) and interleukin-6(IL-6), which were released by macrophages, were reported as potent stimulator of fibroblast proliferation. The goal of this study is to investigate the role of macrophages and tumour necrosis factor-αor interleukin-6 in the interaction of fibroblasts and silicone gel. We designed four groups, two experimental and two control, using Institute for Cancer Research(ICR) mouse peritioneal macrophage and silicone gel. For the preparation of the conditioned medium of macrophages, peritoneal macrophages were prepared and cultured for 24 hours on the silicone gel-coated and naked (not coated) surface [silicone gel-macrophage conditioned medium(SCM; experimental group) and normal polystyrene-macrophage conditioned medium(NCM; control group) respectively]. To correct the effect of 10% fetal bovine serum which was included in Rapid Prototyping and Manufacturing Institute (RPMI) 1640 medium and draw the effect only by macrophages, the RPMI 1640 medium with 10% fetal bovine serum was cultured by the same method on the silicone gel-coated and naked surface (silicone gel-macrophage free conditioned medium; SFM and normal polystyrene-macrophage free conditioned medium; NFM respectively). Each conditioned medium was added onto NIH 3T3 fibroblasts culture at a final 25% concentration of total culture medium and followed by the cultivation for 24 hours. For antibody neutralizing experiments, each conditioned medium was preincubated with polyclonal rabbit anti-mouse TNF-α antibody or polyclonal rat anti-mouse IL-6 antibody for 1 hour and then, conditioned medium with antibody was added to the culture medium of NIH 3T3 fibroblasts by the same method. After 24 hours cultivation, total number of viable fibroblast(cell growth), DNA synthesis and collagen synthesis of fibroblasts with each medium were measured by sulforhodamine B(SRB) assay, 3H-thymidine and 3H-proline incorporation respectively. The results were as follows: 1. In the experiment about the effect of the conditioned medium on the fibroblast activity, the experimental group(SCM), compared with the control group(NCM), showed a significant increase of the cell growth (p<0.01), a significant decrease of DNA synthesis(p<0.001), but no significant difference in the collagen synthesis. 2. In the experiment about the effect of polyclonal rabbit anti-mouse TNF-α antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.01), but no significant difference in the collagen syn thesis. 3. In the experiment about the effect of polyclonal rat anti-mouse IL-6 antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.0001), but no significant difference in the collagen synthesis. In conclusion, culture supernatants (conditioned medium) of peritoneal macrophages, activated by silicone gel, stimulate the NIH 3T3 fibroblast proliferation. TNF-α and IL-6, products of macrophage, are involved in the stimulation of NIH 3T3 fibroblast proliferation in an in vitro condition.

        Proximate analysis, mineral and fatty acid composition of three conventional domestic soybean cultivars and two imported ones including glyphosate-tolerant HS2906 were evaluated by AOAC method, ICP-AES and gas chromatography. There were several differences in the proximate analysis among three conventional domestic soybean cultivars ; higher crude fat in the cultivar Hwanggumkong, higher crude protein in Pungsankong, and higher carbohydrate and crude ash in Duyukong. The ranges of contents of proximate components of domestic cultivars were similar to the data previously reported. There were no significant differences in proximate analysis between conventional soybean WS82 and glyphosate-tolerant HS2906 ; 23.55~23.90% of crudefat, 34.22~35.55% of crude protein, 6.25~6.45% of crude ash, and 25.35~26.47% of carbohydrate. The mineral and fatty acid compositions of HS2906 were similar to those of conventional soybeans previously reported.

        Antidiabetic Activity of Angelan Isolated from Angelica gigas Nakai

        Kim, Hwan-Mook,Kang, Jong-Soon,Park, Song-Kyu,Lee, Ki-Ho,Kim, Jee-Youn,Kim, Yeon-Jin,Hong, Jin-Tae,Kim, Young-Soo,Han, Sang-Bae 대한약학회 2008 Archives of Pharmacal Research Vol.31 No.11

        Angelan isolated from Angelica gigas Nakai inhibits tumor growth and metastasis by enhancing immune functions of macrophages, dendritic cells, and B cells. Here, we report that angelan can inhibit autoimmunity in non-obese diabetic (NOD) mice. Although 80% of the NOD mice had developed diabetes by 24 weeks of age, none of the angelan-treated NOD mice developed diabetes. The mean glucose levels were 118 mg/dl in angelan-treated mice and 506 mg/dl in control NOD mice. Histological examination of the pancreatic islets revealed that most of the islets isolated from angelan-treated mice were less infiltrated with lymphocytes compared with those of control mice. Spleen cells from diabetic NOD mice could adaptively transfer diabetes into NOD.scid mice, but those from angelan-treated NOD mice did not, suggesting that angelan caused the spleen cells to lose the ability to destroy $\beta$ cells. However, angelan did not affect cytokine production of spleen cells. These results suggest that angelan has dual immunomodulatory functions, i.e., immunostimulation in tumor-bearing mice and immunosuppression in autoimmune diabetic mice.

      • Lumbar Intradural Extramedullary Non-Metastatic Carcinoid Tumor: A Case Report

        Kim Young-Mook,Lee Sangpyung,Ryou Kyoung-Soo,Kim Seong-Hwan,Park Tae-Joon 대한말초신경학회 2020 The Nerve Vol.6 No.2

        Carcinoid or neuroendocrine tumors (NETs) are slow-growing neoplasms originating from neuroendocrine cells. The central nervous system(CNS) involvement of carcinoid tumor, not only metastasis to CNS or primary originated, is reported rarely. This study presented a case of a primary spinal intradural extramedullary carcinoid tumor accompanied by urinary incontinence. CNS involvement in carcinoid tumors is rarely reported, and its intradural spinal metastasis or primary spinal NET is extremely rare. A 63-year-old woman came to hospital with urinary incontinence, and a 2.5-cm-sized intradural extramedullary mass was found at the lumbosacral level on spinal magnetic resonance imaging. The patient underwent L5-S2 laminectomy to remove the intradural extramedullary mass at the L5-S1 level. The patient recovered without complications, and there was progress in urinary incontinence. The patient did not complain of urinary incontinence after discharge, and no evidence of recurrence was observed after a 1-year follow-up

      • Efficient Fixation Procedure of Human Leukemia Cells in Sulforhodamine B Cytotoxicity Assay

        Kim, Hwan Mook,Han, Sang Bae,Kim, Moon Soon,Kang, Jong Seong,Oh, Goo Taeg,Hong, Dong Ho 충남대학교 약학대학 의약품개발연구소 1996 藥學論文集 Vol.12 No.-

        The fixation procedures in sulforhodamine B (SRB) assay for human leukemia cells were modified to produce more reliable results. It was found that the concentration of the fixative agent, trichloroacetic acid (TCA), was critical in the selective fixation of cellular protein. While a TCA solution of 80% fixed both cells and serum proteins, a 50% solution fixed only cells with a very low interference of the serum proteins. Accordingly, we selected 50% TCA as a fixative agent which made the final absorbance of the SRB assay to be exactly matched to the cell density with a small deviation and a low background. Besides the change of TCA concentration, a precentifugation of microplate just before fixation also improved the previous assay procedures in the two points of view. The 2-h standing step was simply substituted for only 1 min of centrifugation. Both the rapid and slow application of TCA solution in fixation produced the same extents of fixation. In an actual application, these two kinds of modifications in the previous SRB assay procedure were also proved to be effective in the determination of cytotoxicities of doxorubicin by using human leukemias. ⓒ 1996 Elsevier Science Inc.
