1.Increased expression of the c-fos and c-myc oncogenes in psoriatic lesions.
Korean Journal of Dermatology 1991;29(3):331-336
The expression of the c-fos and c-myc oncogenes was investigated by dot blot analysis of total RNA extracted from biopsies of normal skin and psoriatic lesions. Densitometric analysis revealed 6.3 fold and 8.6 fold evevation respectively of c-fos and c-myc oncogenes mRNA levels in severe psoriasis compared to normal skin, and 1.5 fold and 1.6 fold elevation respectively of c-fos and c-myc oncogenes mRNA levels in mild psoriasis compared to normal skin. The ratio of c-fos/c-myc transcripts in normal skin and mild psoriasis was constant compared to that in severe psoriasis. The maintenance of a constant ratio of c-fos/c-myc is believed to be closely related to ordered cell growth and the ratio of c-fos/c-myc transcripts in severe psoriasis suggests a disordered pattern of cellular differentiation. We be1ieve that overexpression of these oncogenes is related to the pathogenesis of psoriatic epidermal hyperplasia.

We described a giant chroioangioma of the placenta that caused premature rupture of membranes at 31 weeks of gestation in a 31-year-old primiparous woman and a subsequent neonatal death of the baby. The placental mass, weighing 820 gm and measuring 21.5x15x4.5 cm, was easily shelled out from a edematous 1280 gm-placenta. The mass had a thin fibrous capsule and a solid fibromatous appearance. The infant, weighed 2175 gm, appeared edematous oon the whole body and had Apgar scores of 4 and 5 at 1 and 5 minutes respectively. The baby expired 4 days after birth due to high output cardiac failure and respiratory failure. Postmortem examination revealed markedly dilatated umbilical vein, inferior vena cava and right atrium with patent froamen ovale, congestive hepatosplenomegaly, pulmonary hemorrhages, and meconium aspiration pneumonia. Microscopically, the mass revealed a variety of histologic patterns, reflecting entire spectrums of villous vasculogenesis from loose myxomatous connective tissue and undifferentiated hemangioblastic cell nests to well-developed capillaries with hematopoietic cells in the lumen.

Chylothorax is the most common cause of pleural effusion in the neonatal period and is defined as an effusion of lymph in the pleural cavity. We report a case of chylothorax in a 13-day-old male who was admitted due to respiratory difficulty. Chest AP showed pleural effusion of the left lung and milky yellow fluid was aspirated via thoracentesis upon which laboratory and lipoprotein electrophoresis of pleural fluid revealed findings compatible with that of chylothorax. Due to reaccumulation of chyle after daily thoracentesis, chest tube was inserted at the 4th hospital day, and MCT containing diet was given. He was discharged on the 21st hospital day in good health, and revealed no recurrence for 3 months during outpatient follow up visits.

ICAM-l(Intercellular adhesion molecule-1) is an important early marker of immune activation and response. ICAM-1 is expressed on varous cell types and observed in a variety of diseases, including patients with asthma, melanoma, prostatic cancer, ovarian and colon cancer. Some authors demonstrated the expression of ICAM-1 protein in high-grade intraepithelial squamous neoplasia of cervix by immunohistochemistry and suggested that the expression was related to human papillomavirus infection. The aim of this study was to determine the serum levels of soluble intercellular adhesion molecule-1(sICAM-1) in patients with squamous cell carcinoma of the cervix, Serum levels of sICAM-1 were measured by enzyme-linked immunosorbent assay(ELISA), We evaluate invasive squamous cell carcinoma of the cervix (40), carcinoma in situ (16) and control (15) patients. Serum levels of sICAM-1 in healthy volunteers, in parients with carcinoma in situ and invasive cervical cancer were 150.1+/-41.3, 182.7+/-105.9, 189.8+/-60.0 ng/ml, respectively. Although the serum levels of sICAM-1 in patients with carcinoma in situ did not increase, serum levels of ICAM-1 in patients with invasive cervical cancer were significantly increased (control vs invasive cervical cancer, p < 0,05). From the above results, sICAM-1 is shed from the cancerous tissue in patients with squamous cell carcinoma of the cervix.
