Many studies have recently reported on laparoscopic hepatobiliary-pancreas surgery, although its development has been slow compared to laparoscopy in others field. Laparoscopic hepatobiliary-pancreas surgery resection is one of the last areas of resistence to the offensive of the laparoscopic surgery. Diffusion of laparoscopic hepatobiliary-pancreas surgery is still limited to few center, and its result are not yet clarified. The reasons for the limited development of laparoscopic Hepatobiliary-pancreas surgery; First, technical problems are anticipated Second, hemorrhage may be more difficult to control laparoscopically, and the risk of gas embolism may be increased by the use of pneumoperitoneum. The third problem is a fear of oncological inadequacy and tumor spread. The author described here the technical considerations for performing laparoscopic Hepatobiliary-pancreas surgery including indication, operation tips and results of surgery. The conclusion, carefully selected patients, author find laparoscopic hepatobiliary-pancreas surgery to be a usefull surgical procedure.

Objectives : This study was performed to investigate effects of cadmium and zinc on IL-6 secretion using human monocyte in a culture system. Methods : We have used trypan blue dye exclusion methods to examine the effect of cytotoxicity of CdCl₂, ZnCl₂in THP-1 cells. IL-6 was measured by the ELISA method in the cell culture supernatants and the expression of IL-6 mRNA was examined by reverse transcription-polymerase chain reaction. Results : IL-6 production by THP-1 cells were decreased at 0.1 mM cadmium concentration (p<0.05) and increased as zinc concentration increased. Zinc prevented cadmium-induced suppression of IL-6, and the addition of a chelating agent, EDTA, restores IL-6 secretion. The expression of IL-6 mRNA decreased at 0.08 mM and 0.1 mM cadmium concentrations. Conclusion : This results suggest that cadmium depressed production and gene expression of IL-6 in stimulated human monocytes, and zinc prevented cadmium-induced suppression of IL-6.

Cadmium is a highly toxic element responsible for acute and chronic toxicity in man and induces pathophysiological effects by modulating components of immune system. Cytokines are being increasingly recognized as essential mediators of normal and pathologic immune response. The present study has been investigated the effect of cadmium cytotoxicity for lung fibroblast and expression of cytokine gene in unstimulated and cadmium-treated lung fibroblast using reverse transcription-polymerase chain reaction. We showed that cadmium inhibited the cell proliferation and expression of IL-6, TGF-β mRNA in both unstimulated and cadmium-treated cell. The expression of IL-6 mRNA increased at 0.1mM cadmium treated for 24 hours than for 2 hours. This results suggest that cadmium stimulates expression of IL-6 mRNA in lung fibroblast.

The study was conducted to predict the risk of chronic exposure by neurobehavioral test and to use it as a basic source of the management for workers exposed to organic solvents. The exposed group was selected from coating department of textile processing industry. The unexposed group was selected from those who visited the clinic to take an annual check-up. The author administered WHO-NCTB (neurobehavioral core test battery). Also, Scandinavian Questionnaire 16 was tested by self-administration to find the correlation between subjective symptoms and NCTB results, and to assess the availability of the Questionnaire in mass screening test concurrently. The final analysed subjects were 78(27 in exposed group and 51 in unexposed group) workers except who had a neurologic disease or systemic disease affecting the central nervous system. In Questionnaire study, there was no significant difference in total neurotoxic symptom scores between the exposed and the unexposed group. In NCTB, the exposed group had lower mean scores than the unexposed group for all tests. When the effect by age and education were considered, there was a statistically significant difference only in pursuit aming test. This study suggests the availability of NCTB and the Questionnaire for the assessment of neurobehavioral change in workers exposed to organic solvents.

신동훈 大韓齒科保存學會 2003 Restorative Dentistry & Endodontics Vol.28 No.6

Complete understanding of the exterior and interior structure of the tooth would be prerequisite to the successful clinical results, especially in the restorative and endodontic treatment. Although three dimensional reconstruction method using x ray microtomography could not be used in clinical cases, it may be the best way to reconstruct the morphologic characteristics of the tooth structure in detail without destructing the tooth itself. This study was done to three dimensionally reconstruct every teeth in the arch in order to increase the understanding about the endodontic treatment and to promote the effective restorative treatment by upgrading the knowledge of the tooth morphology. After placing tooth between the microfocus x ray tube and the image intensifier to obtain two dimensional images of each level. scanning was done under the condition of 80 keV, 100㎂, 16.8 magnification with the spot size of 8 ㎛. Cross section pixel size of 16.28 ㎛ and 48.83 cross section to cross section distance were also used. From the results of this study, precise three dimensional reconstructed images of every teeth could be obtained. Furthermore, it was possible to see image that showed interested area only, for example. enamel portion only, pulp and dentin area without enamel structure, pulp only, combination image of enamel and pulp, etc. It was also possible to see transparent image without some part of tooth structure. This image might be used as a guide when restoring and preparing the full and partial crown by showing the positional and morphological relationship between the pulp and the outer tooth structure. Another profit may be related with the fact that it would promote the understanding of the interior structure by making observation of the auto rotating image of AVI file from the various direction possible.
