Extraoral maxillofacial prostheses are essential for restoring facial structures that are lost as a result of congenital missing, injuries from accidents, surgical treatments of head and neck cancer. Recently, silicone is the most useful material for this purpose and is more advantageous than other maxillofacial prosthetic materials. However, there are some problems for long-term usage of silicone prostheses due to tear and color change. These are major contributing environmental factors to those problems that are such as ultraviolet light, cleansing agents, changes in humidity and successive adhesion and removal. The aim of this study is to evaluate the physical properties and color changes of maxillofacial prosthetic silicone material by those environmental factors using A-2186 silicone material (Factor II, USA) and two pigments, cadmium yellow medium and cosmetic red. Aluminium molds were fabricated according to the ASTM No. D412 & D624 specifications and resulted specimens from molds were fabicated and treated as follows. Control group and experimental I group were fabricated with 0.1% wt. pigment mixing in silicone elastomer and II-1 group, II-2 group of experimental II group were fabricated with 0.2%, 0.3% wt. pigment mixing in silicone elastomer, respectively. Control group was kept in darkroom at room temperature, I-1 group was kept under natural sunlight during 1week, I-2 group was soaked in 20% soap water during 1wk. I-3 group was successively adhered and removed 200 times on inner region of arm using Daro adhesive-33. Experimental II groups were kept in darkroom at room temperature. Instron universal testing machine was used to measure the % elongation, tensile strength, tear strength of control, experimental I, II groups and reflectance spectrophotometer(COLOR EYE-3000, Macbeth, USA) was used to measure the color differences between control group and experimental I group. The results were as follows : 1. When compared with control group, natural weathering group and 20% soap-water soaking group had no significant differences in % elongation(p>0.05). 2. 200 times successive adhesion and removal group, 0.2% wt. pigment group and 0.3% wt. pigment group had significant decreases in % elongation(p<0.05). 3. Natural weathering group, 20% soap-water soaking group and 200 times successive adhesion and removal group had no significant differences in tensile strength (p>0.05). 4. 0.2%, 0.3% wt. pigment groups had significant decreases in tensile strength(p<0.05). 5. Values of all experimental groups were decreased in tear strength. and 200 times successive adhesion and removal group had significant decrease in tear strength(p<0.05). 6. Natural weathering group and 20% soap-water soaking group had significant color differences(${\Delta}E$) and it could be detectable to naked eye(p<0.05). 7. Color differences between control group and 200 times adhesion and removal group were not detectable to the naked eye (${\Delta}E<1.0$).

Pollution in the fresh water system in urban area has the adverse effect on the amphibians population. Restoration activity of amphibian in the urban stream has been growing in Korea as well as western country. For successful restoration water quality of urban stream should be sufficient for survival and normal development of amphibian. To monitor the biological safety of surface water in the Tancheon basin, the capital area of Korea, a 6-day exposure Bombina orientalis embryo developmental toxicity assay was examined. The toxicity of surface water of Tancheon mainstream were lower than those of tributaries of Tancheon. The survival rate of embryos negatively correlated with total dissolved solid, turbidity and electrical conductivity whereas the developmental abnormality and growth retardation of embryos was positively correlated with total dissolved solid, turbidity and electrical conductivity. An amphibian developmental toxicity assay would be helpful for the selection of point for construction of habitat and reintroduction of amphibian in interrupted urban stream.

Ten-staked Si$_{1-x}$Ge$_x$ quantum wells (QWs) have been grown on (100) n-Si substrates by using rapid-thermal chemical-vapor deposition (RTCVD). The Ge content and the thickness of Si$_{1-x}$Ge$_x$ quantum well were controlled using the GeH$_4$/SiH$_4$ gas ratio. To investigate the structural and the optical properties of ten-staked Si$_{1-x}$Ge$_x$ QWs, we performed transmission electron microscopy (TEM), Sccnning electron microscopy (SEM), high resolution x-ray (HR-XRD), an photoluminescence (PL) measuremennts. For the SiGe QWs, when we used a gas ratio below 5 \% in the cross-sectional TEM images we observed a uniform interface between the SiGe QWs and the Si barrier. On the other hand, for the SiGe QWs when we used gas ratios above 10 \%, the ngerface was not niform and contained island formations. The M-B and P-B models confirmed theoretically that Si$_{1-x}$Ge$_x$ QW layers with thicknessed above a critical thickness could form islands. In order to investi-gate the optical properties of the ten-staked Si$_{1-x}$Ge$_x$ QWs, we performed PL measurement at 10 K. As the GeH$_4$/SiH$_4$ gas ratio was increased, the NP and the TO signals of ten-staked Si$_{1-x}$Ge$_x$ QWs were shifted to the lower energies were in the ranges from 1.035 to 0.894 eV and from 0.980 to 0.849 eV, espect-ively. From the PL data, the Ge contents was determined and wea calculated in the found to be in the range from 17 to 35 \%. 급속열화학증착법을 이용하여 n형 Si (100)기판 위에 10주기의 Si$_{1-x}$Ge$_x$ 양자우물 구조를 성장하였다. GeH$_4$/SiH$_4$ 가스비를 통해 Ge 함유량과 SiGe 양자우물 층의 두께를 조절하였으며, 성장된 시료들의 구조적, 광학적 특성을 확인하기 위해서 TEM, HR-XRD,SEM과 PL을 이용하여 분석하였다. 구조적으로 GeH$_4$/SiH$_4$ 가스비가 5 \% 이하인 시료들은 SiGe 양자우물 층과 Si 장벽층의 계면이 일정하게 성장되는 것을 확인할 수 있었지만, 그 이상의 가스비에서는 양자우물 층이 균일하게 성장되지 않고 islands로 형성되는 것을 확인 할 수 있었다. 또한, Si$_{1-x}$Ge$_x$ 양자우물층이 임계두께이상에서 islands로 형성되는 것을 M-B와 P-B 모델을 이용하여 이론적으로 분석하였다. 또한, Si$_{1-x}$Ge$_x$ 양자우물층의 광학적 특성에서 GeH$_4$/SiH$_4$ 가스비가 증가함에 따라서 SiGe 양자우물 층에 해당하는 photoluminescence(PL) 신호가 낮은 에너지쪽으로 이동하는 것을 확인 할 수 있었으며, PL 신호중 NP 신호는 1.035에서 0.894 eV으로 TO 신호는 0.980에서 0.849 eV로 이동하는 것을 확인 할 수 있었다. 이러한 에너지 신호 이동차이로부터 GeH$_4$/SiH$_4$ 가스비에 따라서 Ge 함유량 (x)을 확인할 수 있었다.

Ascorbic Acid 가 Marcaine 에 의한 Methemoglobin 생성에 미치는 효과

박찬진,우인수,하정성 대한마취과학회 1982 Korean Journal of Anesthesiology Vol.15 No.4

The authors rarely encountered slight cyanotic changes in patients who were given continuous epidural anesthesia with marcaine. Studies for clarifying the causal factors suggested that the occurrance of cyanosis was related to the formation of methmoglobin by continuous epidural anesthesia with marcaine. In these studies, as control, the blood was drawn before injection of local anesthetics by using a heparinized syrings and later the blood sample was obtained at interval one hour during epidural anesthesia and postoperative period. Quantitative assay of methemoglobin was carried out by the Evelyn-Malloy method using a spectrophotometer. The result was that methemoglobin concentration in the peripheral blood after use of marcaine using increased compared with the controls. An animal experiment, rabbit was done and marcaine was injected in the gluteal muscle, revealed same result of human. In the studies of ascorbic acid pretreatment in the human, the authors pretreated with ascorbic acid via the intravenous route before epidural anesthesia and in the rabbit, ascorbic acid was injected into the gluteal muscle before injection of marcaine. The increase of methemoglobin content in the blood appeared to be lesser with pretreatment of ascorbic acid in the patients who were given continous epidura anesthesia with marcaine. It is a recommendable method for reducing mothemoglobin be prior use of ascorbic acid in case of the regional anesthesia with marcaine(Buplvacaine, LAC-43) is used.
