To investigate the effects of ethanol on the lipid metabolism in blood and liver, twenty one male Sprague Dawley rats had orally taken the 25% alcohol and 50% alcohol by 5g per Kg of weight during 3 weeks after the adjusting period. For the energy balance, 85% sucrose and 45% sucrose was added in control group and 25% alcohol group each. The weight was reduced by alcohol treatment according to the levels, otherwise the weight of liver and heart was little increased in alcohol groups rather than in control without significance. Moreover, RBC, WBC, hemoglobin and hematocrit were increased by alcohol treatment according to the levels without significance. Otherwise, adjusted bilirubin levels by 100g of weight was significantly increased by alcohol treatment dose dependently. Alcohol induced RBC degradation and increased circulated bilirubin because of liver damage. For blood lipid profiles, blood cholesterol was increased in 50% of alcohol group compared to that of 25% and control groups, otherwise, blood triglycerides (TG) was increased by 30% in 25% alcohol groups rather than in control but not significantly different. The hepatic lipid composition, cholesterol levels in alcohol treatment groups was lower than those in control. The hepatic TG was not influenced by alcohol treatment. The two reasons of decreasing hepatic lipids were suggested by 85% sucrose of control for energy balance more synthesized cholesterol and TG than those in 25 or 50% alcohol groups, and by cholesterol and TG could not be synthesized because of liver damage from alcohol.

김효명 고려대학교 의과대학 1994 고려대 의대 잡지 Vol.31 No.2

Keratomileusis-in-situ was performed on 18 eyes(15 patients) to correct high myopia. Average preoperative spherical equivalent was -19.26D with a range of -13.25 to -30.50D. The mean postoperative myopia was -4.80D(-0.00 to -9.00D), checked a t 6 month postoperatively. Preoperative corneal power was +41.11D, while it decreased to +35.41D at postoperative 6 months. Of all the cases, there was no significant complication except the one who had irregular astigmatism caused by the epithelial ingrowth in the interface. Uncorrected vision of all the patients improved markedly, compared to those preoperatively. In conclusion, Keratomileusis-in-situ is a feasible technique for correcting high degree of myopia, though the calculation program might be improved to obtain adequate prediction.

As Korean government pusued a policy of unbalanced growth since early 1960s, local economy(small and medium enterprises) has not grown so fast as the whole economy (large enterprises). Further more recent economic environment such as the appreciation of Korean won, wage hikes and the rising protectionism of industrial countries made small and medium enterprises less capable of surviving in this adverse environment than large enterprises, because of their limited capital and disadb antage in raising funds. The problems in financing small and medium enterprises that have been accumulated for the past 30 years are : limited capital of the local banks that should be been centers in financing local enterprises, continuous outflow of the local fund, disintegrated financial assistance programs, poor functioning of the credit guarantee institutions. Economic policy priority should be placed on fostering small and medium enterprises, thus boosting the effects of employment generation and improving industrial flexibility. In the implementation of monetary policy, the following aspects of financial support for small and medium enterprises should be strengthened. First, financial assistance must be increased to support the efforts of small and medium enterprises for structural adjustment to cope effectively with the adverse environment. This will include the increase of investment to enhance productivity and expansion of business activities into new and promising fields. Second, in consideration of the prevailing financial liberalization trend, it is desirable that financial support should be given through enlarging the availability of financing for small and medium enterprises rather than through preferential treatment of them in the interest rates on their bank borrowings. In particular, financing for those enterprises by non-bank financial institutions, the Industrial Bank of Korea, and the Citizens National Bank should be expanded. And also large enterprises with heavy borrowing have to be urged to increase their direct financing through the capital market and to repay their bank loans, thus making funds available for lending to small and medium enterprises. In addition to these, the government needs to be more active in increasing preferential financing for small and medium enterprises at low interest rates. Third, it is desirable to enhance the efficiency of financial support through simplification or integration of the various financial assistance schemes for small and medium enterprises according to the use of funds and the function of financial institutions. In addition, the limited loanable funds for those enterprises should be directed to productive sectors such as parts and materials industry. Fourth, the function of the Korea Credit Guarantee Fund has to be strengthened in order to increase credit guarantees to small and medium enterprises which generally suffer from a lack of adequate collateral. For this purpose, the Fund's financial resources should be enlarged through contributions from the government.

Odontomas are odontogenic harmatomas which are composed of hard dental tissue. This lesion is composed of more than one type of tissue and, for this reason, has been called a composite odontoma. Odontogenic cysts are derived from epithelium associated with the development of the dental apparatus. Dentigerous cyst originated after the crown has been completely formed by accumulation of fluid between the reduced enamel epithelium and the crown. It also associated with crown of impacted tooth. Cystic odontomas are closely similar to dentigerous cysts clinically and radiologically. Treatment of choice is total removal(enucleation) or decompression(marsupialization). We represent two cases of Cystic odontomas with literature review in 69-year old male and 55-year old female occured in anterior maxilla. The leisions were successfully treated by marsupializaion.

N,N-Dimethylaniline의 아조커플링 반응에 關한 硏究

金容仁,明孝信 弘益大學校 1982 弘大論叢 Vol.14 No.2

The coupling reaction of N, N-dimethylaniline with several monosubstituted benzenediazonium salts has been studied kinetically in aqueous buffered solution. The activation evergies measured in the coupling reaction of N, N-dimethylaniliine with diazotized p-nitroaniline, m-nitroaniline, sulfanilic acid, m-anisidine,p-anisidine, p-bromoaniline, p-chloroaniline, m-toluidine, p-toluidine are 8.46, 8.05, 9.20, 12.32, 15.91, 10.86, 11.54, 13.80, 14.35, 15.47Kcal/mole, respectively. The coupling reactionis more favorable in the presence of an electron-withdrawing group in active components than in the presence of electron-donating group. It has been observed that the coupling reaction with diazotized p-nitroaniline proceeds 1000 times more rapidly than that with the benzenediazonium salt, which is coupled 40 times faster than diazotized p-anisidine. In our experiments, the formation of triazene, the diazoamino compound has not been observed, and the experimental result that the ionic strength of the medium didn't give any influence on the coupling reaction rate leads to the confirmation of the neutral free amine being one of the reasonable reactive species in the coupling reaction. A linear free energy relationship has been essentially observed except for three para substituted active components, for which the extended Hammett plot treated by Yukawa-Tsuno permits a good log k/k??=ρ(σ+ rㆍ????) linear relationship when considering the mesomeric effect. The calculated reaction constant of these azocoupling reaction is ρ=3.92, and the reaction constant of resonance contribution is calculated as r=0.32 at 20 ℃.
