BACKGROUND AND OBJECTIVES: N-cadherin is known to be expressed in neuroectodermal tissue such as central nervous system and various mesodermal origin tissues such as kidney and heart. We investigated N-cadherin expression in the endocardial cushion in developing rat heart by immunohistochemical method. MATERIALS AND METHOD: Fetal rat hearts at the 11th, 13th, 15th, 17th, and 19th day of gestation and the 1st day neonatal rat heart were used. Hematoxylin and eosin stain was performed for normal cardiogenesis, and immunohistochemistry was performed for the expression of N-cadherin in interventricular septum(IVS) during cardiogenesis in rat. RESULTS: Ventricular wall and membranous part of the IVS showed positive reaction with anti-N-cadherin at the 11th day of gestation. Membranous part of IVS was begun to show tracely positive reaction at the 15th day of gestation, and thereafter the immunoreactivity was increased with maturation. At the 17th day of gestation mesenchymal cells in membranous muscular part of the IVS showed positive reaction. The similar immunoreactivity of membranous and muscular parts of IVS were shown at the 19th day of gestation. CONCLUSION: As the immunoreaction of mesenchymal cells in the membraneous part of IVS to anti-N-cadherin was increased with time, it is suggested that mesenchymal cells in membranous part of IVS were differentiated into the cardiomyocytes.

Allopurinol is a xanthine oxidase inhibitor widely used to control plasma uric acid levels. Serious and life threatening adverse effects such as the allopurinol hypersensitivity syndrome(AHS) are rare. We describe a 32-year-old female patient who was treated with allopurinol and developed fever, rash, and renal and liver dysfunction.

We are reporting a case of 25-year-old male patient with elastosis perforance serpiginosa who showed multipte serpiginous plaques on his neck. Some of the lesions showed hypopigmented, hard, scar-tissue like plaques in the central part. Histologic examination showed hyperplasia and transepidermal elimination of elastic tissue. By electron microscopy, also, we could prove that the elastic fibers were increased in the dermis.

Kimura's disease is a chronic inflammatory condition of unknown cause. It usually appears as a painless nodule in the head and neck region often associated with regional lymphadenopathy, but there have rarely been reports of penile involvement or clinical presentation as an ulcerative plaque. We present a case of Kimura's disease occurring on the penile shaft as an ulcerative plaque in a 44-year-old man. A vesicular eruption had occurred on his penile shaft followed by an ulcerative plaque for 2 months. He had suffered from recurrent regional lymphadenopathy for 15 years and he had also exhibited intermittent eosinophilia. Histopathologic findings revealed diffuse eosinophilic infiltration in the dermis of the skin and eosmophilic abscesses in the lymphoid follicles of the mguinal lymph node. After short-term systemic steroid therapy and local injection of triamcinolone acetonide, the ulcerative plaque was healed.
