Object : Schedule-induced polydipsia is considered as an animal model of obsessive-compulsive disorder inrats. The authors evaluated the chronic effects of fluoxetine and clomipramine as serotonergic antidepressants and haloperidol as dopaminergic antagonist on the schedule-induced polydipsia in rat.Methods : Spraque-Dawley rats weighing 200-250gm were individually housed, maintained and allowed free access to water for 1 week. And then the rats were placed on a restricted diet. To induce polydipsia, rats were placed in automatic cage where a pellet dispenser automatically dispensed 90mg pellets on a fixed-time 60 seconds(FT 60s) feeding schedule over 150-minute test session for a day. Water was available at all times during the feeding schedule in automatic cage. After 4 weeks of daily exposure to the FT 60s feeding schedule, experimental rats met a predetermined criterion for polydipsic behavior(greater than 3 times of water per session on average). 4 groups of rats were administered fluoxetine(5mg/kg/i.p.), clomipramine(5mg/kg/i.p.), haloperidol(0.1mg/kg/i.p.), vehicle(1cc/kg/i.p.) for 3 weeks. Rats were tested once a week to access schedule induced polydipsic behavior. The chronic effects of experimental drugs on schedule induced polydipsic behavior were analyzed with repeated analysis of variance and Scheffe test as a post-hoc comparison.In order to measure water consumption in non-polydipsic food-deprived rats, a separate group of rats(N=8) were individually housed and given a single bolus(14.5 gm) of food per day which maintained them at their average body weight.Results and Conclusion : The results were as follows ;1) After 4 weeks of daily feeding procedure with fixed time schedule for 60 seconds per day, the experimental group showed significant differences than the control in the amount of water consumption as compared with their baseline water intakes. At the same periods, there were no differences between the experimental group and the control in body weight. 2) The clomipramine treated group and the fluoxetine treated group showed significant decrease in the amount of water intake as compared with their baseline of polydipsic water intakes for 3 weeks of treatment. However, the haloperidol treated group and the vehicle control group showed no changes of amounts of water intake for 3 weeks of treatment as compared with their baseline of polydipsic water intakes. 3) At 2 weeks of drug treatment, clmipramine treated group(16.88±6.51ml) and the fluoxetine treated group(22.50±10.35ml) showed significantly lower amounts of water intake than the haloperidol treated group (41.25±7.06ml) or vehicle control group(37.50±12.54ml). And also the clomipramine treated group(13.75±5.18ml) and the fluoxetine treated group(18.75±3.54ml) showed significantly lower amounts of water intake than the haloperidol group(35.00±11.65ml) and the vehicle control(34.38±6.78ml) at 3 weeks of drug treatment. Above findings suggest that the fixed time feeding procedure for schedule-induced polydipsia as an animal model of obsessive compulsive disorder was effective to the evaluation of pharmacological challenge study. The author confirmed that schedule-induced polydipsia was successfully decreased for 3 weeks of administration of clomipramine and fluoxetine but there was no response to haloperidol.

Asbestos industry has been in operation over 60 years in Korea. However, the prevalence of asbestosis has not been yet reported. With rapid turn-over of workers, previous cross-sectional studies of current workers on the job could not find cases with exposures long enough for the development of asbestosis. This study was done to evaluate asbestosis prevalence of those worksites with operation history of more than 20 years. In total, 139 workers from 5 worksites were examined. Asbestos industries covered in the study include 2 asbestos textile, 1 brake lining, and 2 ship repairing worksites. Chest x-ray was taken from all workers and read by two experts familiar with pneumoconiosis classification according to 1980 ILO guidelines. Those with findings compatible with asbestosis were further ckecked with high resolution computerized tomography (HRCT). Pulmonary function tests were done according to ATS guidelines, and occupational and previous medical history was taken through a standardized interview. Air-borne asbestos was measured according to NIOSH method 7400. The air-borne asbestos concentrations ranged from 0.2-1.3 f/cc for asbestos textile, from 0.7-1.0 f/cc for brake lining, and from 6.3-7.8 f/cc during asbestos removal at ship repairing worksite. Of the 139 workers 25 had abnormal chest radiographic findings, and 10 of them had findings compatible with pneumoconiosis. When work history and current asbestos measurements were accounted, 9 workers who had more than 10 years of asbestos exposure history showed chest radiographic findings of pneumoconiosis with Finally, 4 workers showed finding of pulmonary fibrosis and/or pleural thickening at HRCT, and 2 of them had restrictive lung function changes. The study results showed that, among 139 subjects, there were 4(3%) definite asbestosis cases confirmed with HRCT. The prevalence of probable asbestosis was 7% for 10-14 years of exposure, 13% for 15-19 years of exposure, and 23% for 20 or more years of exposure. The prevalence of compensable asbestosis with abnormal lung function was 4-6% for those with 15 or more years of exposure.

While cultural industry has come out as a representative industry in the world, cultural war has been about to be raged. In this regard, Korea will also definitely need to develop its cultural industry as an outstanding expert-oriented industry along with IT industry relating to semi-conductor, computer, wireless communication, and etc., and persistently tap the door to the foreign market. The social phenomenon of Hanliu which means Korean stream has recently been widespread in China through Korean TV dramas and popular music. By taking advantage of this, the government and relevant circles of companies in Korea have begun to make serious and true efforts to enter the Chinese cultural market. Accordingly, the purpose of this study is to review the basic policy, history, overall vision, and targets towards the cultural industry of China, the socialist country which has a different political and economic system from us and consequently, to provide fundamental data to set up the marketing strategy with which Korean can maintain and utilize Hanliu longer and effectively in China.

하악과두에 발생된 골연골종

정기훈,김은경 大韓口腔顎顔面 放射線學會 1993 Imaging Science in Dentistry Vol.23 No.2

Although osteochondroma is not rare in the axial skeleton and long bones, it is very rare in the jaw. It is a benign chondroma within which partial endochondral ossification occurs. There are two types, the central one and the peripheral one. Peripheral type is more common than central one in the jaw, but it is not frequent. Especially it is rare at the mandibular condyle. When it occurred at the mandibular condyle, it is generally located at lateral portion of the condyle. In that case, facial asymmetry with occlusal change is the characteristic clinical feature. But it is similar to condylar hyperplasia so that misdiagnosis can sometimes occur. The differential point is as follows: Hyperplasia generally appears as a generalized enlargement of the condylar process with a normal cortical thickness, but osteochondroma usually appears as focal growth or mass. We report a very rare case of peripheral osteochondroma at the mandibular condyle in a 27-year-old male patient who visited DKUDH with a chief complaint of the facial asymmetry.

The results obtained from the experiments about the chemical compositions and the product quality of Lycium Chinense M?? and Chaenomels Sinensis K??? in Korea are summarized as follows: 1. The concents of proximate components of Lycium Chinense M?? were hgiher in the Jindo-products than that of the Kongju-products, except the content of crude protein of Jindo-products which was the least one(12.7%). 2. The content of Vitamine A, one of the special components of Lycium Chinense M???, was varied from 1.4mg% to 55.1mg%. It was thought because that samples were affected by the several factors during storage. 3. The Fe content of Lycium Chinense M??? of Jindo-products(11.2∼11.9mg%) was higher than that of Kong-ju-product.(6.6mg%) 4. Comparing the parched Lycium Chinense M??? with dried one, the contents of Vitamine A, volatile acid and total ester were decreased from 1.7 to 0.5mg%, 0.24 to 0.01mg% and 3.9mg% to 1.2mg%, respectively. But it was found that the contents of alkoloid and mineral were not changed. 5. In ungrafted seedling, the contents of the tested minerals except for phosphorous(18mg%) were higher than those of the other species. 6. The extracted powder tea was best according to the panel test. 7. There was no significant difference among the Lycium Chinense M??? liguors in taste, flavor and color. 8. By means of panel test on Chaenomeles Sinensis Koehne tea, the significant difference about taste and flavor of each sample was recognized and grinding fresh fruit sugared tea was the best.
