Adenosine deaminase (adenosine aminohydrolase, E.C.3. 5. 4. 4; ADA), which catalyzes the deamination of adenosine to yield inosine and ammonia, was characterized in the human penile foreskin. ADA was found to be present in both layers of the skin with slightly higher activity in the epidermis(Epidermis; (7. 2+2. 3) * 10-4 unit/mg protein, Dermis;(5. 7 +1. 9) *10-4 unit/mg protein). The enzyme exhibited a broad pH optimum from 6. 5 to 8. 0 in both layers of the skin, and was heat-labile, being completely inactivated by heat treatment at 70C-75 C for 10 minutes. In contrast to the ADA of other tissue, the enzyme was inhibited by 2 mM of Cu2+, Fe2+ and Co2+ at pH7. 0 in both layers of the skin. The inhibitory effect of Cu2+ on the enzyme was stronger than other metal ions, and the enzyme was completely inactivated by 20 mM of Cu2+ in both layers. The Cu2+ inhibited enzyme activities which were recovered by adding EDTA. From the above results, it is suggested that the enzyme in both layers of the skin are consisted of same types of isozymes.

Inflammatory pseudotumors of the bronchus have been reported infrequently. Histologic diagnosis remains difficult because of their Polymorphic histologic characteristics and confusing terminology, which are also the problems in the diagnosis of intrapulmonary pseudotumors. We report a case of inflammatory pseudotumor in the left main bronchus which occurred in a 37-year-old man. Histologically, the main portion of the tumor was composed of pale eosinophilic spindle shaped cells covered by respiratory epithelium with squamous metaplasia. Mononuclear inflammatory cells, including plasma cells but acute inflammatory cells were also present in the superficial portion.

Adenomatoid tumor of the uterus is a rare benign neoplasm which has been known as mesothelial origin. Characteristically, it appears as a small nodular lesion less than 2.0cm in the myometrium of subserosal region. We describe a case of giant adenomatoid tumor of the uterus having multicystic gross appearance. A 49-year-old woman complained of vaginal bleeding. The tumor was an intramural mass with maximum diameter of 10 cm and located at posterior wall of the uterus. Histologically, the tumor was composed of multiple cystic cavities of variable size lined by flattened cells, lying among thin septa of connective tissue. Immunohistochemically, the cells are positive for low molecular weight cytokeratin(CAM 5.2) and are negative for factor VIII.

Strumal carcinoid of the ovary is a rare turkor characterized by an intimate mixture of thyroid follicles and carcinoid. Herein is reported an ovarian strumal carcinoid in a serous cystadenoma from a 27-year-old pregnant woman. The thyroid follicular epithelial cells had immunohistochemically thyroglobulin and carcinoid tumor cells contained neuron-specific enolase, chromogranin and carcinoembryonic antigen. In addition, carcinoid cells showed neuroendocrine granules ultrastructurally. Calcitonin and amyloid were not found. This tumor may be originated from pluripotent endodermal germ cells on the basis of morphologic, immunohistochemical and ultrastructural studies.

Medical records of very low birth weight infants weighing less than 1500 grams at birth were reviewed and analyzed. One hundred and forty three infants who were admitted to neonatal intensive care unit of Presbyterian Medical Center, including those who were born and transferred from other hospitals, from January 1987 to December 1991 were examined and the following results were obtained; 1) The incidence of very low birth weight infant was 1.21% 2) The most common maternal risk factor was premature labor and the next was toxemia. 3) The most common disease of very low birth weight infant was neonatal hyperbilirubinemia and the next was septicemia. 4) Twenty five infants (38.5%) of intensive care group and 67 infants (85.9%) of Not-ventilated group survived with overall survival rate of 64.6%. 5) The heavier birth weight and longer intrauterine period were factors offering better chance for survival. 6) Among 43 (30%) infants expired, 7 (16.3%) died within 24 hours after birth, 12 (27.9%) died in second or third day, 4 (9.3%) died between fourth and seventh day, and 20 (46.5%) died between eighth.and twenty eighth day.
