To clarify the developmental characteristics of fetal esophageal epithelium especially ciliated cell, expressions of epidermal growth factor receptor (EGFR) and cytokeratin (CK) in fetal esophageal mucosa (16-24 weeks of gestation) were studied immunohistochemically, and ultrastructure of the ciliated cells was also observed. The expressions of EGFR and CK were identified in labelled streptoavidine biotin immunohistochemical method. Primary antibodies used were EGFR (Ab-4) which is affinity-purified from hyperimmune rabbit sera (Oncogene Science) and monoclonal mouse anti-human cytokeratin (DAK0-CK, MNFl16). The esophageal lumen was lined with stratified ciliated columnar epithelium between 16 and 24 weeks of gestation. The pattern of expression Of EGFR was different with gestational age and epithelial layer. The ciliated cell exhibited variable staining intensity for EGFR at 16 weeks. Some were stained intensively, and others were stained faintly. Number of ciliated cells stained intensively were gradually increased, and most of them were strongly stained at 24 weeks. The superficial non-ciliated cells, however, showed relatively constant staining property of moderate to intense between 16 and 24 weeks. EGFR immunoreactivity was minimal in the basal and intermediate cells at 16 weeks, but became more intense at 24 weeks. CK immunoreactivity in the ciliated cells between 16 and 24 weeks was similar to that of EGFR immunoreactivity. On the other hand, superficial non-ciliated cells were intense for CK staining at 16 weeks, but were very weak to negative at 24 weeks. CK immunoreactivity was intense in basal and intermediate cells between 16 and 24 weeks, but it was almost negative in the some cells of intermediate layer, especially beneath negatively stained non-ciliated cells, at 24 weeks. In electron microscopy, ciliated cells had well organized cilia and dense granules close to Golgi apparatus between 16 and 24 weeks. The cells apparently active in ciliogenesis were also observed. These cells had short microvilli, many centrioles, and dense granules close to Golgi apparatus. The non-ciliated cells contained numerous clear vesicles adluminally clustered at 16 weeks, while they had many dense vesicles of about same size of clear vesicles at 24 weeks. These results demonstrate the expressions of EGFR and CK in esophageal epithelium of human fetus between 16 and 24 weeks of gestational ages, and suggest that the ciliated cells are still proliferative at 24 weeks.

Acquired digital fibrokeratoma is an uncommon, solitary, round, firm, more or less hyperkeratotic projection, most frequently situated on fingers or toes but occasionally on the other locations. It arises out of a collarette of slightly raised skin and may have slight or great resemblance to a rudimentary supernumerary digit or may be mistaken for some other more ordinary condition such as an odd cutareous horn. We experienced a case of acquired digital fibrokeratoma on the right second finger in a 25-year-old male. We treated it with total excision.

There have been reported cases that the Krukenberg Tumor had been primary ovarian carcinoma. But the Krukenberg Tumor is generally known as one special type of metastatic ovarian carcinoma, which histologically consists of nest of mucin filled signet-ring cells in a cellular, nonneoplastic stroma. The most common gastrointestinal tract origin for Krukenberg tumor is the stomach, and the next frequent is the large intestine. Generally the Krukenberg tumor is difficult to diagnose and treat until somewhat enlarging its size. We experienced a case of the Krukenberg tumor on the remained ovary after the previous unilateral adnexectomy, which was metastasized from adenocarcinoma of stomach. We present this case with a brief review of literature.

This study was aimed at evaluating the nutritional status of Korean lactating women, who were attending peripheral community clinics in low-income areas, by anthropometric measurement, estimating dietary intakes and analyzing the contents of breast milk components, serum lipid content and fatty acid composition. Regarding anghropometric measurements, maternal circumferences decreased significantly at the trunk but not at the limbs. The skinfold thickness on all regions had the tendency to decrease during lactation. It was found that intakes of energy, protein, lipid and carbohydrates were desirable while calcium, zinc, copper and vitamin A were low and sodium was excessive. The energy % of fat was 22.41% of the total energy which is higher than the RDA for adults but it is proper for lactating women, but energy % from each fatty acid was usually low and an intake ratio of omega6/omega3 fatty acids was desirable. Accordingly, it is thought that dietary fat intake was balanced in quality. Concentrations of the nutrients in matured human milk showed the same range as that reported form different regions with the exception of calcium and magnesium which were relatively low. Serum lipid contents were decreased with the time postpartum and the average serum lipid content of lactating women were similar to the normal range of adults. Serum polyunsaturated fatty acids. especially omega6 fatty acids have gradually increased with the time postpartum, but the composition were not greatly influenced by dietary intakes.

BACKGROUNDS: An inhibitory effect of magnesium L-ascorbyl-2-phosphate (VC-PMG, a stable derivative of ascorbic acid) on melanogenesis has been described. Furthermore, glabridin in licorice is known to have inhibitory effects on melanogenesis and widely used for raw materials for depigmenting agents. OBJECTIVE: The purposes of this study are to provide objective data by measuring the visual clinical effects of VC-PMG with the colorimeter and to promote the development of de-pigmenting agents. METHODS: 20 volunteers joined the study. With an artificial UVB irradiation, eight tanned areas were made on the inner side of the forearm. During two months, each tanned area was treated with five whitening cosmetics with 3% VC-PMG and increasing concentration of licorice from 0% to 3%. Darkness degree of each area was measured weekly by the colorimeter and the visual assessment. RESULTS: For all cosmetics, whitening effect was measured by colorimeter and visual as-sessment. The cosmetic containing VC-PMG 3% and licorice 1% had more whitening effect than any other cosmetics of different concentrations. Moreover, VC-PMG 3% alone also had whitening effect in some volunteers. CONCLUSION: VC-PMG was clinically found to have whitening effect.

To determine the impact of intake large amount whole cow's milk (WCM) on iron status during early childhood (18~36 months), selected indices of complete blood count(CBC) and iron status were compared between the WCM large amount intake group (n=20)and small amount intake group (n=20). WCM large amount intake children's mean hemoglobin and mean hematocrit were 9.6+/-1.7 g/dL and 30.8+/-4.5% respectively. These range of peripheral blood with other indices of CBC disclosed the hypochromic microcytic anemia. WCM large amount intake children's some indices of CBC-hemoglobin, hematocrit, MCV, MCH-were significantly lower than those of small amount intake children (P<0.01). WCM large amount intake children had significantly lower mean iron, transferrin saturation and ferritin (P<0.01) and greater mean total iron binding capacity (P<0.05) than did small amount intake children. It is concluded that intake large amount of WCM for long duration impacts on the iron status of 18~36 months old children disadvantageously. It should be avoided for the protection of irreversible recognitive impairment and behavioral change.

Antibiotic therapy for acne is now considered one of the most effective regimen. Thirty years ago, oral antibiotics were introduced for acne vulgaris and topical preparations have been available by prescription for more than 15 years. Recently, clindamycin, erythromycin and tetracycline were regarded as the most effective and widely used antibiotics. Many authors reported that clindamycin was a mast effective topical antibiotic for acne vulgaris but side effects, i.e., contact dermstitis or pseudomembranous colitis were reported. The author studied the clinical effectiveness and side effects of Fabrys salution, which has been used as an antiseptic and keratolytic agents, and Fabrys solution containing chloramphenicol or clindamycin. Fifty three patients who were followed for 6 weeks were studied. They were divided into three groups: group I was treated with Fabrys solution(F solution), group II was treated with Fabrys solution containing chloramphenicol(F-c solution) and group Ill was treated with Fabrys solution containing clindamycin(F-cd solution).
