BACKGROUND: Smoking increases the risk of respiratory, cardiac diseases and cancer. This study is to ascertain the relationship between passive smoking, the modes of residence, its location and the immunoglobulin values as well as the eosinophil counts in relation to child patients suffering from bronchial or cardiac asthma. METHODS: The research was conducted at a general hospital with cooperation of 242 patients who had been hospitalized 1991 through 1995. We compared the average values of immunoglobulin between the groups of exposed and non-exposed to smoking by T-test. A same work for residential modes was done by T-tests, while the data regarding the residing locality were processed by ANOVA. RESULTS: Each values of TEC, IgE, IgA, and IgM in both groups has been analysed but spelling no significant differences. The group residing in apartments showed lower value of IgM than those of flats. CONCLUSIONS: The reason the IgM value of apartments is lower than that of flats is due to the difference of living quarters. This signifies the modes of residence may as well affect the IgE value.

BACKGROUND: Acromioclavicular (AC) stability is maintained through a complex combination of soft-tissue restraints that include coracoclavicular (CC), AC ligament and overlying muscles. Among these structures, the role of the CC ligament has continued to be studied because of its importance on shoulder kinematics, especially after AC injury. This study was designed to determine the geometric change of conoid and trapezoid ligaments and resulting stresses on these ligaments according to various scapular motions. METHODS: The scapuloclavicular (SC) complex was isolated from a fresh-frozen cadaver by removing all soft tissues except the AC and CC ligaments. The anatomically aligned SC complex was then scanned with a high-resolution computed tomography scanner into 0.6-mm slices. The Finite element model of the SC complex was obtained and used for calculating the stress on different parts of the CC ligaments with simulated movements of the scapula. RESULTS: Average stress on the conoid ligament during anterior tilt, internal rotation, and scapular protraction was higher, whereas the stress on the trapezoid ligament was more prominent during posterior tilt, external rotation, and retraction. CONCLUSIONS: We conclude that CC ligament plays an integral role in regulating horizontal SC motion as well as complex motions indicated by increased stress over the ligament with an incremental scapular position change. The conoid ligament is the key structure restraining scapular protraction that might occur in high-grade AC dislocation. Hence in CC ligament reconstructions involving only single bundle, every attempt must be made to reconstruct conoid part of CC ligament as anatomically as possible.

There has been numerous experimental liver transplantation models in the rodent : orthotopic versus hetrerotopic; whole liver versus partial liver; microvascular suture versus cuff method in technical aspects. Several simplified modifications were introduced for experimental liver transplantation for improving animal-survival rate. Liver transplantation without arterial reconstruction, the cuff tchnique or stent method were the examples of simplifing modification. In practice, complications related to biliary reconstruction are frequent causes of intraabdominal infection in our rat liver transplantation. Here we propose using simple liver transplantation model of partial heterotopic liver transplantation without artery and bile duct reconstruction in the studies which need only observation of immediate graft survival or very short-term follow-up. Here we examined the serial histologic changes of auxiliary liver grafts without biliary reconstruction during short period after transplantation. Until 7 days of transplantation, bile duct proliferation was confined in the portal area of grafts and did not distort the lobular structure. Early graft-survival and rapid immunologic response might be evaluated by this easy transplantation model.

To determine the difference in cephalometric measurements between centric relation and centric occlusion, 60 patient-20 patients for each malocclusion group-were examined with the cephalograms in centric relation and in centric occlusion. The results are as follows: 1. There are differences in cephalometric measurements with the mandible in the two different position, and some measurements are statistically significant. 2. No clinically useful prediction may be made from cephalometric radiographs concerning the amount of mandibular deflection from centric relation to centric occlusion. 3. If, the large differences in the cephalometric measurements with the mandible in the two different position, the analysis with the cephalogram in centric occlusion is needed to be compensated with the other clinical approach.

The purpose of this study was to investigate the cytotoxicity of orthodontic bands in vitro and in vivo.4 types of orthodontic bands were applied to cultured fibroblast and the supermatants were injected into dorsal subcutaneous tissue of mice. In vitro, the cytotoxixity was evaluated by an MTT assay after 2 and 6days.In vivo, the histopathologic observation was performed 2 days after injection. The results were: 1. The cell viability was significantly decreased in the group added phosphoric acid in comparison to control group, but there was not any significance among the experimental group after 2 days. 2. Cell viability decreased in the high Ni containing group after 6 days. 3. The histopathological finding was that the Cr-containing group showed severe infiltration of inflammatory cells and muscular destruction.
