To know the amplification pattern according to relative concentration ratio in mixed samples, two STRloci, vwF locus and MBP locus and two VNTR loci, D1S80 locus and d17S5 locus were amplified in DNA with various concentration of two individuals were easily identified. But when the concentration of one person were lowered to 1/20-1/40 of the other's the intensity of product bands diminshed and hardly discernible. Also different amplification efficiency according to the template length was noted, especially in VNTR loci. Using automatic sequencer and RFLP scan program, the intensity OD of each PCR product band could be calculated, and this correlates the felative amplification efficiency of each allele. By using this we could construct quantitative PCR for the mixed samples. This could be used in practical case work for forensic purpose, and also be a valuable candidate for 'chimerism detection' in case of bone marrow transplatation.

Lichen myxedematosus (synonym, papular mucinosis) is a disorder characterized by lichenoid papules, nodules and plaques due to dermal mucin deposition, and a variable degree of fibrosis without thyroid dysfunction. Discrete lichen myxedematosus is a subtype of the localized lichen myxedematosus. Clinically, firm, smooth, waxy or flesh-colored papules measuring 2 to 5 mm in diameter, numbering just a few to hundreds, and involving limbs and trunk. The lesions progress slowly without systemic symptoms and rarely resolve spontaneously. Histologically, the upper and mid dermis shows edema and diffuse or focal mucinous deposit under normal epidermis. Fibroblast proliferation is variable, but there is neither collagen deposition nor sclerosis. On experiencing a case of discrete grouped papules on the arm and thigh of a sixty three year-old women, we present it as discrete lichen myxedematosus.

Porokeratosis*

Nontuberculous mycobacteria usually cause systemic disease and often appear as a primary pulmonary infection. However, a cutaneous lesion may be the first or only sign of infection. The most frequent human diseases caused by Mycobacterium fortuitum are cutaneous or soft tissue infections, usually preceded by injection, trauma or surgery. We report a case of a cutaneous lesion due to Mycobacterium(M.) fortuitum occuring in a 50-year-old man with a subcutaneous flat nodule on his left anterior tibia. He had received a small injury to his left shin in a swimming pool. The culture from the skin biopsy specimen on Lowenstein-Jensen medium yielded clolnies after 5 days. The microorganism was subsequently identified as M. fortuitum by selected biochemical reactions. Therapy was instituted with minocycline for 5 months.
