Mullerian Mucinous papillary Cyatadenernas of Borderline tumor(MMBT) is lined by mucinous epithelium of endocervical type and is characterized by papillae architecturally similer to those of serous horderline tumors, It has been described rarely in the literature, Thia case was reported with a brief review of the concerened literatures. It has important clinical and pathological diBerences from mucinous birderline tumors with intestinal differentiation, but has many similatities to mixed epithelial borderline tumora of Mulierian type. Recently, a case of MMBT in a 22 years old woman was experienced at our department. We presented this case with a brief review of literature.

BACKGROUND: Oculocutaneous albinism (OCA) is a genetic disorder of the melanin pigment system in which melanin synthesis is reduced or absent in the skin, hair, and eyes. OCA is classified into two major types, and tyrosinase-related OCA can be produced by mutations of the structural gene for tyrosinase enzyme (TYR gene). OBJECTIVE: The purpose of this study was to analyze the segregation of mutant alleles of the TYR gene in tyrosinase-negative and tyrosinase-positive Korean OCA patients and families. METHODS: We amplified exon I, II, and III of the TYR gene of Korean OCA patients and their families by polymerase chain reactions (PCR), and analyzed the mutations by restriction fragment length polymorphism (RFLP) analysis in exon I and single-strand conformation polymorphism (SSCP) analyses in exon II and exon III. RESULTS: Two tyrosinase-negative cases showed mutations in exon I. Four tyrosinase-nega-tive cases and one tyrosinase-positive case showed mutations in exon II, and one tyrosinase-neg- ative case showed mutations in exon III. In summary, we found three kinds of mutation in four tyrosinase-negative OCA patients and one tyrsinase-positive OCA patient. CONCLUSIONS: RFLP and SSCP analysis can provide a basis for a rapid and sensitive screening system to detect TYR gene mutations of Korean OCA patients and their families.

BACKGROUND: Defective adhesion and migration of melanocyte may be involved in pathogenesis of vitiligo. Tenascin, a glycoprotein of the extracellular matrix, has a role in cell adhesion and migration. It has been reported that abundant expression of tenascin in vitiligo lesion may inhibit melanocyte adhesion and migration. OBJECTIVE: To investigate the tenascin expression in vitiligo skin lesions and to compare with clinical findings. METHODS: We studied 9 patients with vitiligo. The expressions of tenascin were studied by immunahistochemieal techniques.

BACKGROUND: Atopic dermatitis, characterized by dry, flasky, easily irritated skin, is the most common form of dermatitis seen during childhood. Infants with atopic dermatitis and other eczematous conditions need special dermatologic care to hydrate their skin and to minimize contact with irritants or allergens. OBJECTIVE: The purpose of our study is to evaluate the safety and efficacy of the skin products developed for children. METHODS: Twenty-eight normal children and 26 children with atopic dermatitis were evaluated clinically after using following commercal skin products : (lotion, cream, shampoo, soap, face wash wash) for 2 weeks. Water content of the skin of 14 volunteers was measured serialy over 8 haurs at 2 hour intervals after the application of each skin product. The skin pH of 16 volunteers was also measured serialy over 60 minutes at 30 minute intervals after application. We performed visual skin erythema grading, skin erythema grading by dermaspectrometer, transepidermal water loss measurement, skin water content measurement, and keratinocyte morphology observation by D-squame after the application of the skin products to 13 volunteers for 4 days.

Use of electric pulp testing elicits painful response in vital teeth. In this study, we examined the excessive time from pain feeling to stimulation disconnection in clinical situation. D626D (Parkell Inc., USA.) scan type electric pulp tester was used in total of 23 young healthy individuals. Each of the right central incisors and first premolars were used as testing teeth. Stimulation disconnection was achieved by EMG in anterior belly of digastric muscle, finger span, and voice and the excessive stimulation time over the sensory threshold was recorded. As a result, we found that the short responses before the stimulation disconnection appeared following order; EMG, finger span, and voice. The EMG disconnection is suggested to be used to reduce the excessive stimulus time in electric pulp testing.

The androgen insensitivity syndrome is a heterogeneous disorder with a wide spectrum of phenotypic abnormalities, ranging from complete female to ambiguous forms that more closely resembles males. Mutations of the androgen receptor gene are responsible for a variable degree of impaired androgen action. The complete androgen insensitivity syndrome is characterized by normal female external appearance in spite of the normal male karyotype 46XY with testes and normal testosterone production and metabolism. This is transmitted by X-linked recessive manner. Wolffian duct does not develop. However, m llerian development does not occur in presence of antim llerian hormone activity. Recently we experienced a case of complete androgen insenditirity syndrome. We reported a case with concerned literatures.
