        하악골에 발생한 골막 골육종

        김태우,김승범,권혁찬,문선재,윤정훈,김형준,차인호,육종인,김진 대한악안면성형재건외과학회 2002 Maxillofacial Plastic Reconstructive Surgery Vol.24 No.1

        Periosteal osteosarcoma is a distinct entity of malignant bone tumor with characteristic clinical, morphological, and histological features within the group of juxtacortical osteosarcoma. Periosteal osteosarcoma is predominantly located in the tubular long bones, and extremely rarely involving the jaws. A case of periosteal osteosarcoma of the right mandible is presented. A 27-year-old woman complained of the gingival swelling and bleeding tendency of the right posterior mandible. Clinical examination revealed a reddish brown strawberry-like swelling on the affected mucosa, which measured 1.5㎝×1.5㎝. The tumor was located on the lingual cortex of the mandible and extended into the surrounding soft tissues. Microscopically, the tumor consisted exclusively of atypical chondroblastic cells with a small osteoblastic area. A minimal bone marrow involvement was noted and the adjacent cortex was free of tumor. These findings suggested that the tumor originated from the periosteal cambium layer, which lies between the periosteal fibrous layer and the cortex of mandible.

        흰쥐에서 반복적 스트레스가 GABA성 신경전달에 미치는 영향

        김창수,이종범,성형모,시현석,김진성,박형배,정성덕,하정희 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.1

        연구목적 : 일반적으로 생체는 각종 스트레스에 반응하여 적응(adaptation) 기전이 나타난다. 이러한 적응 기전과 관련하여 포유동물의 중요한 억제성 신경전달계인 GABA성 신경전달계의 스트레스성 자극에 대한 반응양상에 대한 연구가 진행되고 있다. 신경전달의 변화양상은 부하된 스트레스의 종류 및 기간에 따라 다양하게 나타나므로 더욱 상세한 연구를 필요로 한다. 방 법 : 본 연구에서는 하루 2시간의 부동화 스트레스를 반복적으로 2주간 부하한 흰쥐의 뇌조직에서 GABA성 신경전달의 변화 양상을 관찰하고자 하였다. 수용체 결합반응을 통하여 GABA 수용체의 각 component별 배위자들의 각 수용체에 대한 결합 반응의 변화 양상을 정상 대조군와 비교하여 보고, 유의한 변화가 있는 부분의 상세한 검정을 위하여 포화결합반응을 통하여 친화력(Kd) 및 최대결합력(Bmax)에서의 변화양상을 검색하였다. 뿐만 아니라 GABA성 신경전달에 관여하는 중요한 신경전달체인 내인성 GABA의 함량과 대사효소인 GABA transaminase의 활성도의 변화양상도 검색하였다. 결 과 : 연구결과 반복적인 부동화 스트레스는 GABA 수용체 효현제인 [³H]muscimol의 흰쥐 뇌조직 GABA 수용체에 대한 결합도에는 별다른 영향을 미치지 않았다. 대뇌피질조직의 GABA 대사효소인 GABA transaminase 활성도를 감소시켰으나, 피질조직외의 다른 조직의 GABA transaminase 활성도나 내인성 GABA의 농도에는 별다른 영향을 미치지 않았다. 반복적인 부동화 스트레스를 부하한 흰쥐의 대뇌피질, 해마 및 시상하부 조직에서는 [³H]flunitrazepam의 수용체 결합도가 감소하였으며, 포화결합 반응결과 수용체의 수가 감소하였음을 확인하였다. 결 론 : 이상의 결과를 요약하면, 흰쥐에게 부하한 반복적인 부동화 스트레스는 뇌조직의 benzodiazepine 수용체의 수를 감소시킴으로써 GABA성 신경전달을 감소시키며, 이러한 GABA성 신경전달계의 변환은 생체에서 스트레스로 인한 행동장애의 한 기전이 될 수 있을 것으로 생각되었다. Objectives : Changes of GABAergic neurotransmission in response to the application of different types of environmental stress have been the subject of research for over two decades. However, the nature of the changes induced by stress appear to show a dependent phenomena on the type and duration of stressor agent employed. Methods : For this reason, this study was performed to observe the effects of repeated stress on the radioligands binding to GABAA/benzodiazepine receptors of discrete brain regions. The author also examined the activity of GABA transaminase and the concentration of endogenous GABA. Male Sprague-Dawley rats, weighing 150-200g were forced to suffer an immobilization stress for 2 hours during 14 consecutive days. Results : Repeated immobilization stress decreased the binding of [3H]flunitrazepam on the benzodiazepine receptor in the cortex, hippocampus and hypothalamus. Saturation experiments followed by scatchard analyses of the results showed decreased density of benzodiazepine receptor and the affinity remained unchanged. Repeated immobilization stress did not affect the binding of [3H]muscimol on the GABAA receptor, the activity of GABA transaminase, and the concentration of endogenous GABA in the brain regions. Conclusions : From these results, it can be concluded that repeated immobilization stress modulated GABAergic neurotransmission via downregulation of the benzodiazepine receptor in the brain.

        Curcumin ameliorates cadmium-induced nephrotoxicity in Sprague-Dawley rats

        Kim, Kyeong Seok,Lim, Hyun-Jung,Lim, Jong Seung,Son, Ji Yeon,Lee, Jaewon,Lee, Byung Mu,Chang, Seung-Cheol,Kim, Hyung Sik Elsevier 2018 Food and chemical toxicology Vol.114 No.-

        <P><B>Abstract</B></P> <P>Chronic exposure to cadmium (Cd) causes remarkable damage to the kidneys, a target organ of accumulated Cd after oral administration. The aim of the present study was to investigate the protective effect of curcumin against Cd-induced nephrotoxicity. Sprague–Dawley male rats were divided into the following four treatment groups: control, curcumin (50 mg/kg, oral), CdCl<SUB>2</SUB>, (25 mg/kg, oral), and pre-treatment with curcumin (50 mg/kg) 1 h prior to the administration of CdCl<SUB>2</SUB> (25 mg/kg, oral) for 7 days. At 24 h after the final treatment, the animals were killed, and the biomarkers associated with nephrotoxicity were measured. Our data indicated that blood urea nitrogen (BUN) and serum creatinine (sCr) levels were significantly reduced by curcumin pre-treatment in CdCl<SUB>2</SUB>-treated animals. Histopathological studies showed hydropic swelling and hypertrophy of the proximal tubular cells in the renal cortex after Cd treatment. Pretreatment with curcumin ameliorated the histological alterations induced by Cd. The urinary excretion of kidney injury molecule-1 (Kim-1), osteopontin (OPN), tissue inhibitor of metalloproteinases 1 (TIMP-1), neutrophil gelatinase-associated lipocalin (NGAL), and netrin-1 significantly reduced by curcumin treatment compared to that in the CdCl<SUB>2</SUB>-treated group. The administration of curcumin provided a significant protective effect against Cd-induced nephrotoxicity.</P> <P><B>Highlights</B></P> <P> <UL> <LI> Curcumin protects against cadmium-induced renal injury. </LI> <LI> Curcumin reduces urinary excretion of AKI biomarkers. </LI> <LI> Curcumin protects against cadmium-induced apoptosis in the kidney. </LI> </UL> </P>

        Ocllratoxin A는 fenicl'flrium과 rtsr☞rgiffus 속 등의 곰팡of가 생성하는 mycotoxin으로서 세포매기성 및 체액성 면역기능에 슨상을 일으키는 것으로 알려져 있다. 본 연구는 OTA가 면역계에 미치는 영향과 OTA의 면역 독성 억제 효과가 있는 물질을 검색하기 위하며 6~7 주령의 Balb/c mice 비장세핀에 T 및 B 세포의 mitogen인 Con A와 LPS로 처리하고 3일간 배양한 후 비장세포의 분화정도를 MTS를 처리하여 관찰하였으며, OTA를 투여한 마우스의 면역장기 형리조직학적 견화를 관찰하였다. 마우스의 비장세포 (2xtD6cel1/rnf)에 OTA(1~6μg/ml)를 상에서 혼합하여 Con A와 LPS로 자극시킨 결과 임파구는 Sfg/mf이상에서 거의 모든 세포가 분화되지 않았다. mice에 OTA (1,5 및 10mg/11g)를 2일 간격으로 6회 복갚 주사한 후 비장세포를 분리하여 Con A와 LPS로 처리한 결과 Smg 투여군에서는 6회 투여 혼에 분화가 억제되었고, 10mg 투여군에서는 3회 및 6회 투여군에서 분화가 억제되었단. Ochratoxin A의 면역독성 억제 효과가 있는 물질을 검색하기 위하여 in vitro 실험에서 마우스의 비장세포 (2×10" cell/mf)에 OTA (3fg/mf)와 L-phenylalanine, indole-3-carbinol, L-ascorbic acid,piroxicaTn, curcumin 및 arethylsalicylic acid를 혼합하고 동일 처리한 결과 L-ascorbic acid, L-phenylala-nine 및 Indole-3-carbinol은 OTA의 면역독성 발현을 운의성 있게 억제하였다. Balt/c mice에 OTA (10mg/kg)와 l'n pifro실험에서 억제효파가 확인된 L-ascorbic acfd, L-phenylalanine 및 indole-3-carbinol을 2일 간격으로 동시에 3회 복강주사하여 관찰한 결과 indote-3-carbine께서 엮제효과를 관찰할수 있었다. Ochratoxin A를 투여할 마우스의 비장 및 홍선에서는 임파구의 빈도가 줄었으며 특히 비장제서는 starry-sky 세포가 증가됨을 관찰할 수 있었다. 이러한 결자로 OTA는 비장세포의 T 및 B 임파구의 분열능을 억제시 키며, 면역장기의 임파구에 손상 야기시키므로서 면역기능을 저하시키고 OTA에 의한 면역독성은 indole-3-carbinol이 경감시킴을 관찰하엿다. Ochratoxin A (OTA) is a Tnyeotoxin produced by several fungal species iBcluded the genera fs4pergiffug and f☞HiciHiHuL and known as one of the major environmental contaminants. Tn thepresent study, the effects of OTA on the imraune system and the prevention of the OTA-inducedimmunosuppression by protective agents were studied in Balb/c rnicf:. Splenocytes were isolated and theproliferative responses to concanavalin A (Con A) and lipopolysaccharide (LPS) were measured in thepreseEce of 1 to 6fg/mf OTA. Sfg/mf OTA completely btocked both Con A and LPS-stimulatedmitogenic responses, causing approximately 50% inhibition at 3fe/mf OTA. This suppression of mitogen-induced proliferative resplonses observed id uifro was reproduced in mice treated with ☞rA in rioafntraperitoneal administration of 5, IDmg/kg OTA 3 to etimes every other day significantly decreasedboth Con A- aud LPS-inttuced mitegenic responses. The effects of possible protective agents on theOTA-induced suppression c)』 mitogenic responses were examined both in uifro and in viua Amoag 6 pos-sible protective agents (1,-phenylalanine, L-ascorbic acid, indole-3- carbinol, curcumin, firoxicam,acethylsaricylic acid) employed in the present study, L-phenylalanine (100ff), L-ascorbic acid (100#M) and iBdote-3-carbinel t 10Df) showed significantly protective effects on the OTA-iBduced suppres-sion of mitogenic responses id uifro. Howeuer, when the protective of·fects of these agents were examinedin rr'ua only indole-3-carbinol showed significantly protective respoases. It has been ebserved that Iyin-phatic cell population in thc spleen and thymus was decreased in raice given OTA by hematoBylin-eosinstaining. These data indicate that OTA suppresses the cell-mediated and humoral immune functioBsand this OTA-iBduced supflression of immune functions can he alleviated by indole-3-carbinol.

        Identification of a sensitive urinary biomarker, selenium-binding protein 1, for early detection of acute kidney injury

        Kim, Kyeong Seok,Yang, Hun Yong,Song, Hosup,Kang, Ye Rim,Kwon, JiHoon,An, JiHye,Son, Ji Yeon,Kwack, Seung Jun,Kim, Young-Mi,Bae, Ok-Nam,Ahn, Mee-Young,Lee, Jaewon,Yoon, Sungpil,Lee, Byung μ,Kim, Hyung TAYLOR & FRANCIS 2017 Journal of Toxicology and Environmental Health Vol.80 No.9

        <P>Acute kidney injury (AKI) is associated with increased mortality rate in patients but clinically available biomarkers for disease detection are currently not available. Recently, a new biomarker, selenium-binding protein 1 (SBP1), was identified for detection of nephrotoxicity using proteomic analysis. The aim of this study was to assess the sensitivity of urinary SBP1 levels as an early detection of AKI using animal models such as cisplatin or ischemia/reperfusion (I/R). Sprague-Dawley rats were injected with cisplatin (6 mg/kg, once i.p.) and sacrificed at 1, 3, or 5 days after treatment. Ischemia was achieved by bilaterally occluding both kidneys with a microvascular clamp for 45 min and verified visually by a change in tissue color. After post-reperfusion, urine samples were collected at 9, 24, and 48 hr intervals. Urinary excretion of protein-based biomarkers was measured by Western blot analysis. In cisplatin-treated rats, mild histopathologic alterations were noted at day 1 which became severe at day 3. Blood urea nitrogen (BUN) and serum creatinine (SCr) levels were significantly increased at day 3. Levels of urinary excretion of SBP1, neutrophil gelatinase-associated lipocalin (NGAL), and a tissue inhibitor of metalloproteinase-1 (TIMP-1) were markedly elevated at day 3 and 5 following drug treatment. In the vehicle-treated I/R group, serum levels of BUN and SCr and AST activity were significantly increased compared to sham. Urinary excretion of SBP1 and NGAL rose markedly following I/R. The urinary levels of SBP1, NGAL, TIMP-1, and KIM-1 proteins excreted by AKI patients and normal subjects were compared. Among these proteins, a marked rise in SBP1 was observed in urine of patients with AKI compared to normal subjects. Based upon receiver-operator curves (ROC), SBP1 displayed a higher area under the curve (AUC) scores than levels of SCr, BUN, total protein, and glucose. In particular, SBP1 protein was readily detected in small amounts of urine without purification. Data thus indicate that urinary excretion of SBP1 may be useful as a reliable biomarker for early diagnosis of AKI in patients.</P>
