This study was conducted to investigate the subacute transdermal toxicity of Syndella gel, a new topical drug containing deproteinized dialysate of calf''s blood and micronomicin sulfate in Sprague-Dawley rats. Three doses (1.97, 3.94, 7.88 g/kg) of Syndella gel was daily treated transdermally to male and female rats for 30 days. No death was occurred in either control or treated rats. No significant toxic clinical signs and body weight change were not observed at any doses in the male or female rats treated. There were no significant alterations in hematologic and biochemical parameters in both sexes, however slight increase of potassium concentration was observed in 3.94g/kg and 7.88 g/kg female groups. No significant necrotic changes were not observed in examined organs. This study showed that up to 7.88g/kg Syndella gel did not induce subacute transdermal toxicity.

원형 용융탄산염 단위 연료전지의 성능 및 온도분포가 수치모사를 통해 얻어졌다. 원형 단위전지내에서는 사각형 단위전지에 비해 비교적 균일한 온도분포가 얻어졌다. 전지의 바깥쪽으로 갈수록 가스전환율이 커졌고 전류밀도도 크게 증가하였다. 운전전압이 감소할수록 각 가스들의 전환율은 커지고 전류밀도도 커졌다. 원형 전지에서의 평균전류밀도나 출력은 전압이 높을 때는 사각형 전지보다 작았고, 전압이 낮을 때는 더 컸다. 음극 및 양극 가스의 전환율도 마찬가지였다. 전압이 낮을 때 가스의 전환율이 커서 원형 전지의 효용성이 크게 나타났다.

By using Pheonics, each operating variable had effects on what kind of efficient of MCFC. The basic structure of MCFC is made up of separate plate, fuel gas channel, cathode electrode, electro-catalyst plate, anode electrode, oxidizer gas channel, and separate plate. About unit fuel cell (length 1cm, width 1.4cm), generation and consumption of CO2 were calculated by using Pheonics. In the simple form of MCFC, we supposed that consumption of CO2 was happened by the electrode reaction at cathode and generation of CO2 was happened at anode. As the counted results in Pheonics, amount of the consumption of CO2 at cathode was counted according to the processing direction of gas. Amount of the consumption of H2 and H2O were counted according to the generation of CO2. According to the processing direction of gas, amount of CO2 transition, distribution of pressure and temperature were counted at electric chemical velocity coefficient of surface K1 and 10K1.
