단백 methylase 억제제 5´-Isobutyl-5´-deoxyadenosine과 sinefungin에 의한 BALB/c mouse 비장세포의 증식과 분화의 억제

최의규,홍정희,한유정,백문기 大韓免疫學會 1995 大韓免疫學會誌 Vol.17 No.3

Whether or not protein methylation can be correlated with cell proliferation and differentiation in BALB/c mouse splenocyte cultures has been investigated by using methylase inhibitors, 5'-Isobutyl-5'- deoxyadenosine(SIBA) and sinefungin. 1) Protein methylase I and III activities were found to be elevated in LPS stimulated splenocytes, and the peak of protein methylase I was correlated with that of S phase fraction while changes in protein methylase III activity followed the changes in S phase fraction. 2) SIBA and sinefungin were proved to be potent competitive inhibitors of the protein methylase 'I and III in vitro with apparent Ki for sinefungin of both enzymes being lower than that for SIBA. 3) The protein methylase III were activated by 2-mercaptoethanol and dithiotreitol, and strongly inhibited by Cue+ in vitro; and the inhibition was almost completely released by dithiotreitol and diethyldithiocarbamate. 4) The extent of polyclonal antibody formation, S phase fraction and protein synthesis after induction by LPS were significantly inhibited in a dose response manner by SIBA and sinefungin with higher potency for the former. 5) Inhibition of cell cycle was also observed in the presence of cyloleucine, an inhibitor in SAM synthesis. 6) Of several enzymes investigated, namely protein methylase III, LDH, yglutamyltranspeptidase, and adenosine deaminase, the- protein methylase III was most markedly increased by LPS and decreased by SIBA and sinefungin than other enzymes. From the above results, it is suggested that SIBA and sinefungin suppress the cell proliferation and differentiation through the inhibition of protein methylation.

최평호,김범식,이정민,김철웅,구기갑,이상학 한국공업화학회 2004 공업화학 Vol.15 No.1

새로운 지지형 액막(SLM)을 용매 증발에 따른 1차, 2차 상분리법으로 3성분 고분자 용액으로부터 제조하였다. 액막재로 이온액인 BMIBF_(4) (BMI+ =1-(1-butyl)-3-methylimidazolium, BF_(4)=tetra-fluoro boratr)와 매트릭스 고분자로 polyvinylidenefluoride(PVDF)가 사용되었다. 이 고정화 액막의 O_(2), N_(2) 그리고 CO_(2) 기체 투과특성을 여러 조작 조건에서 조사하였다. SLM은 가혹한 조건에서 조작하였음에도 불구하고 오랜 시간동안 높은 CO_(2) 투과도 및 선택성을 유지하였다. 투과거동을 나타내는 인자인 투과도, 확산도, 그리고 용해도를 연속 측정 장치를 통하여 구함으로써 특성을 관찰하였다. SLM은 다른 기체에 비하여 CO_(2)에 대해서 높은 투과도와 선택도를 갖고 있었다. 특히, 막내 CO_(2)의 용해도는 다른 기체들에 비하여 매우 높은 반면 확산도는 큰 차이를 보이지 않았다. 또한 막내 이온액의 조성은 CO_(2) 용해도에 영향을 관찰할 수 있었다. 막내 이온액의 조성이 증가함에 따라서 CO_(2) 의 투과도 및 선택도가 극격히 증가하였다. 이는 SLM를 통한 기체 투과에 있어서 용해도가 주인자로 큰 영향을 끼침으로써 막내 이온액 조성 증가 SLM의 투과에 큰 영향을 미침을 확인하였다. The new supported liquid membranes (SLMs) were fabricated from ternary polymer solution contained ionic liquid in which primary and secondary phase separations were induced by the solvent by the solvent evaporaton. The used ionic liquid and polymer matrix were BMBF_(4) (BMI+=-(1-butyl)-3-methylimidazolium, BF_(4)-tetra-fluoro boratel and polyvinylidene fluoride (PVDF). Gas permeation properties of the SLM to O_(2), N_(2) and CO_(2) were studied at various operating conditions. Although the SLM were operated under severe operating condition, it maintained high CO_(2) permeability and selectivity for quite long time. The solubility coefficient of CO_(2) in the membrace was very high in comparison with those of other gases; whereas there was no big difference in the diffusivity between CO and other gases. Moreover, in the permeation of pure gases, it is observed that the ionic liquid content in the membrane affected the solubility of CO_(2) in the memhranc. With increasing ionic liquid content in the membrane, the permeability and selectivity of CO_(2) increase significantly. There fore, in the permeation of gases through SLM, the overall permeation performances weir affected mainly by solubility coefficient. This observation can be discussed in terms of the influence of solubility coefficient with ionic liquid content in the membrane.

1. Hypophosphatasia 는 골조직 및 치아조직의 비정상적인 석회화를 나타내는 대사장애로, 특징적구강내 소견 인 우치의 조기탈락 양상으로 치과에서 조기진단이 가능하다. 2. 본 증례에서 상악궁 확장을 동반한 의치 제작으로 심미적, 기능적으로 양호한 결과를 얻었으며, 영구치열기 까지 장기적 관찰 및 치료가 필요할 것으로 사료된다. hypophosphatasia is a rare metabolic disorder which manifests characteristics such as abnormal mineralization of bone and dental tissues, diminished serum and tissue alkline phosphatase, and increased urinary secretion of PEA. It ingerited as an autosomal recessive or dominant trait and occurs in all races. In general, hypophosphatasia can be classified in 4 subtypes which are the perinatal, infantile, childhood, adult type depending upon the age at presentation and severity. In young children with Hypophosphatasia the long bones show irregular defects, and the skull showes poor calcification. In older children with premature closure of the skull sutures there may ve multiple lucent area called gyral or convolutional markings, described as resimbling beaten copper, presumably resulting from increased intracranial pressure,Examination of the jaws reveals a generalized lucency of the maxilla and mandible, the cortical bone and lamina dura are thin, and the alveolar bone may be deficient. Clinical features of Hypophosphatasia imclude premature loss of deciduous teeth, especially incisors, hypoplasia of aplasia of root cementum, enamel hypoplasia, irregular calcification of dentin, large pulp chamber, and resorption of marginal alveolar bone and roots. Our report involves a patient with a chief complaint of early loss of both Mx. and Mn. deciduous ncisors. after conducting a through clinical and radiographic examination this patient was referred to pediatrics under the suspicion of hypophosphatasia, the diagnosis proved to be correct and successful results were accomplished through a denture made to improve esthetics and function.
