Burn injury is occuring often in our living environment. But there has been little report on the treatment of burn on the basis of Oriental medicine. So we experienced a 53 year old female with second degree burn on the feet and reported the result of the treatment for her with Acupuncture, Herb-med, Negative therapy and Light therapy.

Objectives : Atopic dermatitis is a recurrent or chronic eczematous skin disease with severe pruritus. Although the pathogenic mechanisms of atopic dermatitis are yet unknown, recently hyperresponsive Th2 cells in the acute phase are reported as the important mechanisms. Cheonggisan(CGS) is used in oriental clinics for curing acute skin lesions of eczema, atopic dermatitis or urticaria. There have been no studies on the therapeutic mechanism of CGS for curing atopic dermatitis. We aimed to find out the therapeutic mechanism of CGS on atopic dermatitis, so we observed Th2 cell differentiation in EL 4 cells and $NF-kB$ p65 activation in RAW 264.7 cells. Materials and Methods : EL 4 cells were induced the increase of IL-4 mRNA expression by phorbol-12-myristate-13-acetate(PMA) and 4-tert-Octylphenol(OP) and treated with CGS extract. RAW 264.7 cells were induced the increase of cyclooxygenase(COX)-2 mRNA expression by lipopolysaccharide(LPS) and treated with CGS extract. Results : The PMA and OP induced IL-4 mRNA expression was dose-dependantly decreased in CGS treated EL 4 cells. The LPS-induced COX-2 mRNA expression was dose-dependantly decreased in CGS treated RAW 264.7 cells. Conclusion : The results may suggest that the CGS inhibits Th2 cell differentiation in EL 4 cells and inhibits $NF-kB$ p65 activation in RAW 264.7 cells.

Allergic conjunctivitis is frequent 90% of allergic reaction of eyes. It is difficult to know the cause, so it is impossible to keep away from the antigens. The purpose of the treatment is just subsiding the symptoms without side effects. We experienced one case of Allergic conjunctivitis treated with oriental medical treatment, acupuncture and herbal medication. 27 year-old male patient had diagnosed Allergic conjunctivitis by western medical doctor. He suffered from eye itching, so he couldn't sleep well. After treatment his itching was subsided and he could sleep well. Therefore, oriental medical treatments could be safe and effective methods.

The purpose of this study was to examine the machining of texture shapes by the contour fitting data. The hardware of the system was composed of PC and scanning system, CO₂ laser machine. There were four steps, (1) text image loading using scanning shapes or 2D image files, (2) generation of contour fitting data by the line and arc, cubic Bezier curve, (3) generation of NC code from the contouring fitting data, (4) machining by the DNC system. It was developed a software package, with which can conduct a micro CAM system of CNC laser machine in the PC without economical burden.
