In order to study the morphological changes of Corti’s organ in the rat treated with cisplatin and tobramycin, thirty-three rats, weighing between 200∼250g, were used, and divided into 4 groups, i.e., 3 rats were used for control, and 30 rats were used for 3 experimental groups. Each experimental group was divided into cisplatin-treated, tobramycin-treated, and both cisplatin and tobramycin treated group with 10 rats. Rats were injected with a single dose of 7.7㎎/㎏ of cisplatin intraperitoneally and 50㎎/㎏/day of tobramycin for 2 days intramuscularly, respectively or both. Treated rats were sacrificed on the 3rd and 5th day after the first injection. Results were as follows; 1. Cisplatin-treated group: Outer hair cells of Corti’s organ were degenerated with the formation of vacuoles and appearance of lysosomes, however, inner hair cells showed mild vacuolization. 2. Tobramycin-treated group: NO pathological changes were found in Corti’s organ. 3. Combined cisplatin and tobramycin treated group: Outer and inner hair cells showed vacuolization, appearance of lysosomes, myelin figures and multivesicular body. There were also multivesicular body in the inner phalangeal cell and myelin figure in the Reissner’s membrance. 4. Degeneration of Corti’s organ in the combined treated group was more sever than those of the single cisplatin-treated or tobramycin-treated group. 5. NO pathological differences of Corti’s organ in duration of postinjection were manifested in any groups. It can be concluded that cisplatin induces toxicity to inner ear and cisplatin enhance toxicity more in continued treated with tobramycin.

김영철,차경훈,신무경,임건한,김주영,안병수,김장만,양경철,박도영,오재욱,장인엽 조선대학교 2003 The Medical Journal of Chosun University Vol.28 No.1

Background and Objectives : Interstitial cells of Cajal(ICC) are the pacemakers in gastrointestinal tract that modulates gastrointestinal motiliey and these cells also transmit neural input from enteric nerves to smooth muscles. Recent work on tissues from patients with motility disorders that suggest that loss or defect in ICC could be related to pathophysiology in human and animal models. Immunolabelling of ICC in intestinal wall is recently developed by using specific marker, anti-c-kit antibody. Immunohistochemistry was done for ICC network in attempt to provide a morphological basis for the mechanism regulating gastrointestinal motility Methods : Cryosection was done, and whole-mount preparations of mouse stomach, gastrointestinal tract were immunolabelled using the anti-c-Kit. Immunolabelled ICC networks were observed under a confocal laser scanning microscopy. Results : According to three dimensional reconstruction study, we found that the c-Kit-positive celluar networks were widely distributed in the gastrointestinal muscle (1) circular muscle layer(IC-IM), (2) myenteric plexus(IC-MY), (3) deep muscular plexus(IC-DMP) in ileum, (4) submucosal plexus(IC-SMP) and longitudinal muscle layer(IC-LM) in colon. Conclusion : The characteristic profiles of ICC celluar networks provide a morphological basis upon the mechanism regulating gastrointestinal motility. Additional studies for the enteric nerves-ICC interaction are need to evaluate the detailed roles of Icc in gastrointestinal tract.

The authors studies the effects of Nicotine on the Body weight growth of the developmental chick embryo. On the sixth day of incubation, 0.41mg, 0.82mg and 1.65mg of Nicotine were injected into the chorioallantoic sac of each egg of three groups and one group was injected physiological saline solution as a control, and the eggs were broken for weighting the body weight in every other day from the twelfth day to eighteenth day of incubation. In an attempt to analyze the growth of the body weights, growth formula of Zimmerman and relative growth formula of Huxley were applied. The following results were obtained. 1. The growth of chick embryo boby weight was affected as inhibiting by the Nicotine. The inhibiting effects were in proportion to the injected Nicotine dosage. 2. The growth quantity of the body weight injected 1.65mg was almost half weight of the control group body weight. 3. Growth rate was decreased continuously with tine until 18th day in the 1.65mg injected group but it was increased in 0.41mg and 0.82mg injected group with time lapse from 12th day to 18th day, and 0.41mg injected group was more increased than 0.82mg injected group. 4. Specific growth rate decreased in the all of 0.41mg, 0.82mg and 1.65mg injected group and in the decrease degree 1.65mg and 0.82mg injected group ware severe and 0.41mg injected group was slight. 5. Growth centers of growth gradient were 12th day in the 0.41mg injected group and 18th day in the 0.82mg and 1.65mg injected groups. 6.

김영철,신기식,박상동,최무혁 대한건축학회 2004 대한건축학회논문집 Vol.20 No.6

The atrium in a building is a popular design skill due to its aesthetic, open appearance. It is relatively inexpensive to build and maintain atrium, and also we can expect energy saving effect. But its indoor space is thermally different from typical space because of its tall and large shape with top light. The upper part of atrium has the thermal problem of overheating during summer season. As one of the measures to solve this problem, the ventilation windows near the top light can be used. In this study, the vertical temperatures in the atrium were measured and analysed to understand the thermal environment in the atrium and the effect of ventilation window to reduce the overheating at the upper part of atrium. The ventilation windows were proved to have the effect to lower the temperature of the upper part of atrium as 3.8℃ at the condition of outdoor air temperature of 28℃.

The area of the various epithelial types linging the nasal navity of each six number in 1-week-old and 10-week-old adult ducks has been made for the light microscopic research. Transverse sections of 10 microns thick in each specimen were made continuously from the anterior end of nostril to the posterior end of pharyngeal inlet and specimen samples were selected at 0.13mm(1-week-old) and 0.17mm(10-week-old) intervals from the anterior end of the nasal cavity to the posterior end of pharyngeal inlet. The results obtained from research were summarized as follows. 1. The nasal cavity is lined with stratified squamous, respiratory and olfactory epithelium. The thickness of stratified squamous, respiratory and olfactory epithelium is 10-100㎛, 8-75㎛ and 50㎛ respectively in 1-week-old ducks, and 25-175㎛, 20-125㎛ and 66㎛ respectively in 10-week-old ducks. 2. The unilateral volumes of the nasal cavity in 1-week-old and 10-week-old ducks were 21.73±2.64㎟, 1,692.44±171.57㎟ respectively. 3. The total unilateral surface areas of the nasal cavity in 1-week-old and 10-week-old ducks were 70.44±4.92㎟, 1,772.45±94.10㎟ respectively. 4. Each area of the stratified squamous epithelium, respiratory epithelium and olfactory epithelium in unilateral nasal cavity is 14.82±1.85㎟ (21.1%), 46.86±3.20㎟ (66.5%) and 8.76±0.40㎟ (12.4%) in the 1-week-old ducks, and 348.23±40.02㎟ (19.7%), 1,282.31±47.03㎟ (72.3%) and 141.90±12.43㎟ (8.0%) in the 10-week-old ducks. Ducks are assumed as a microsmatic animals by the composition of the lining epithelium of the nasal cavity in ducks.
