We have usually experienced bone conduction impairment in chronic otitis media, but it is unclear that raised bone conduction threshold is due to the reflection of cochlear dam- age and / or Carhart effect ( an artificial elevation of bone conduction threshold due to conductive defect ) or both. The purpose of this study is to verify the influence of the artificial elevation of the bone conduction threshold in chronic otitis media and to estimate Carhart effect. A total of 336 cases of tympanoplasty with unilateral chronic otitis media without any other causes of sensorineural hearing loss was studied. The average threshold levels of the bone conduction in diseased ears ranged from 18.5dB at 4kHz to 12.1dB at 250Hz The longer duration of the disease, the larger perforation size, the more severe damage of the middle ear structure and the presence of the cholesteatoma made bone conduction threshold increased. The postoperative thresholds of bone conduction were Improved in 36 cases (40.4%) of the 89 cases that underwent operation with type I tympanoplasty technique without electrie drilling. The degree of the maximal improvement was 14.3dB at 2000Hz and the minimum was 8.8dB at 250Hz. but these result did differ from a statistically significant degree. The result suggest that the bone conduction threshold in chronic otitis media is elevated artificially by conductive defect and improved by successful reconstructive surgery.

This experiment was conducted during the period from September 2, 1982 to June 5, 1983 in order to examine the suitable planting time and growing condition in Cheju Island using the Sourthem garlic (Cheju jaere) and Nourthem garlic (6-clove garlic). 1. The earlier the garlic was planted, the higher the top part growth and 6-clove garlic decreased more than in early period. However, rather higher than Cheju jaere from the beginning of May. 2. The earlier the Cheju jaere was planted, the plant weight, top part weight increased remarkable more than 6-clove garlic. 3. As the bulb index was below 0.5 in the bulb formation of Cheju jaere, there was no difference between the planting time, but because the bulb formation of 6-clove garlic was over 0.5, the bulbing was slowing down. 4. Cheju jaere differentiated the clove in March. 10 and 6clove garlic April. 2 but the earlier the garlic was planted, the earlier clove differentiation and there was about 25 days difference between two varieties. 5. The later the Cheju jaere garlic was planted, the secondary growth increased. However, the earlier the 6-clove garlic was planted, the secondary growth increased.

To develop and aceclofenac soft capsule, four preparations with various solubilizers were prepared and their dissolution test was carried out. Among four preparations tested, a preparation with ethanolamine was selected a formula of aceclofenac soft capsule (Clanza S^(™), since it showed the fastest dissolution rate. Bioequivalence of aceclofenac tablet, Airtal^(™)(Dae-Woong Pharmaceutical Co., Ltd.) and aceclofenac soft capsule, Clanza S^(™)(Korea United Pharmaceutical Co., Ltd.) was evaluated according to the guideline of KFDA. Fourteen normal male volunteers (age 20-25 years old) were divided into two groups and a randomized 2×2 cross-over study was employed. After oral administration of one tablet or capsule containing 100 ㎎ of aceclofenac, blood ws taken at predetermined time intervals and the concentration of aceclofenac in plasma wa determined with an HPLC method under UV detector. The pharmacokinetic parameters (C_(max), T_(max) and AUC_(t)) were calculated and ANOVA was utilized for the statistical analysis of parameters using logarithmically transformed AUC_(t), C_(max) and T_(max) between Airtal tablet and Clanza soft capsule were 2.89%, 0.18% and 43.0%, respectively. There were no sequence effects between two formulations in these parameters. The 90% confidence intervals using logarithmically transformed data were within the acceptance range of log(0.8) to log(1.250(e.g.log(0.81) - log(1.23) and log(0.89) - log(1.14)) for AUC_(t) and C_(max), respectively. Thus, the criteria of the KDFA guidelines for the equivalence was satisfied, indicating that Clanza S^(™) soft capsule is bioequivalent to Airtal^(™) tablet.

Background: The current treatments of acute myocardial infarct(AMI) Include noninvasive method using thrombolytics and invasive methods such as primary percutaneous transluminal coronary angioplasty(PTCA) and coronary artery bypass graft(CABG)surgery. Although there are many studies comparing the effectiveness of noninvasive and invasive methods, when large clinical centers, 20% of totar hospitals, were excluded, most middle-sized hospitals lacked personnels and facilities for the invasive methods. Thus they opted for the noninvasive methods. Therefore, in this study, the clinical characteristics of AMI patients and the results of thrombolytic & conservative treatment were observed. Method: 137 patients with acute myocardial infarct, who visited KonKuk University Medical Center, ChoongJu Hospital during Sept. 1990 to Sept. 1999 were analysed retrospectively using medical records. Result: The sexual compositions of patients were 63.5% male, and 36.5% female. The mean age for male patients were 56±12.9, and for female patients 68.7±9.6 (p<0.05). The mean age for female patients was significantly older than male patients. The patients in the thrombolytic treatment group had mortality rate of 6.25% which is lower than that of the conservative treatment group at 12% (p>0.05). Conclusion: Although in our study, small number of acute myocardial infarct patients caused the statistical insignificance, rapid revascularization by thrombolytic therapy within 6 hours of onset of symptoms improved mortality rate and early ambulation. And we had good results on AMI with thrombolytic agent in ChungJu including near rural area as primary emergency hospital. Therefore a prospective research with greater number of subjects is needed to develop better treatments for AMI.
