Mutation of the p53 gene frequently results in overexpression of the p53 protein and loss of its tumor-suppressing properties. The overexpression of the p53 gene could be an indicator of rapid proliferation, poor differentiation, advanced stages, or poor prognosis. The prognostic value of the overexpression of the p53 gene in colorectal carcinoma is equivocal. The presence of DNA aneuploidy has been described as a powerful adverse prognostic indicator in relation to survival. To investigate the prognostic significance of p53 expression, and the relationship with DNA ploidy, 92 cases of colorectal carcinomas were analyzed. The overexpression of p53 gene product was present in 50(54.4%) of 92 cases. p53 expression only correlated with recurrence or metastasis during the follow-up periods (p=0.045). DNA aneuploidy was observed in 32(39.1%) of 82 cases. DNA ploidy was strongly associated with lymph node invasion(p=0.005), Dukes' stage(p=0.003), TNM classification (p=0.003), and recurrence or metastasis during the follow-up periods (p=0.045). The frequency of DNA aneuploidy was higher in the p53-positive colorectal carcinomas(58.3%) than in the p53-negative colorectal carcinomas (21.6%) (p=0.003). p53-positive colorectal carcinomas had a higher rate of cell proliferation than p53-negative cases(p<0.001). These results suggest that checking the p53 expression and DNA ploidy could be useful prognostic indicators of colorectal carcinoma.

Trachea is lined by a pseudostratified epithelium which usually expresses a complex mixture of stratified as well as simple epithelial-type cytokeratins. In the present work, the cytokeratin expressions was studied immunohistochemically in the tracheal epithelium and gland of human fetus at 14, 26 and 32 weeks of gestation. The primary antibodies used were CK7, 8, 10, 14, 18, AE8, 5D3, MNFl16 and AE3. In PAS-hematoxylin stain, the tracheal eithelium was composed of pseudostratified ciliated columnar type and consisted of surface, intermediate and basal layers regardless of gestational ages. The PAS positive cells, however, were decreased in number in proportion to gestational ages. The tracheal gland was not fully differentiated at 14 weeks of gestation, and had well differentiated secretory portions consisting mucous and serous cells at 26 and 32 weeks of gestation. The mucous cells and luminal border of the duct were positive for PAS stain. The tracheal eithelium showed different immunoreactivity between cartilageous and membranous portions. In general, CK7 and 5D3 were expressed in surface cells, AE8 in intermediate cells, and MNFl16 and AE3 in the cells of all layers. At 14 weeks of gestation, the tracheal epithelium immunoreacted for CK7, AE8, 5D3, MNFl16 and AE3. The premordium of tracheal gland was positive for 5D3, MNFl16 and AE3. The tracheal epithelium at 26 and 32 weeks of gestation showed same staining properties to those at 14 weeks of gestation. The duct cells at 26 weeks of gestation were immunoreactive for CK7, 8, 14, 18, AE8, 5D3, MNFl16 and AE3, and those at 32 weeks of gestation were immunoreactive for CK7, 14, 5D3, MNFl16 and AE3. The acinar cells at 26 and 32 weeks of gestation were positively stained for CK7, 8, 18, 5D3, MNFl16 and AE3. These results suggest that CK7 and 5D3 may serve as useful markers for mature cilated cells, AE8 (CKl3) for immature ciliated cells, and CKl4 for duct cells in tracheal epithelium and gland.

Terrys nail(TN) might be causally associated with cirrhosis or other disorders, but his criteria have been proved to be inadequate reflection of systcmic disorders. Modified criteria of Holzberg and Walker were introduced in TN examination in 1984. Using these criteria, fingernails were studied in 444 medical inpatients with chronic systemic diseases at Taegu Catholic Hospital from March 1991 to March 1992. There were 136(30.6%) patients with TN and 308(69.4%) patients without TN, respectively. Ninety-three patients with TN showed a signifiart association with cirrosis(49/86, 57%, p<0.01 by the x-test), congestive heart failure 18/35, 515, p<0.05), and diabetes mellitus(25/51, 49%, p<0.05), and otherwise not;ignificantly associated with chronic renal failure(19%), and cancer(18%). Male and female patients with TN were affected about equally. Age distribution in The patients with TN showed 35(25.8%) the age group from twenty to fortynine and 101(74.2%) in the age group from fifty and above with a mean age of 57.3+14.0, whereas the patients without TN had 178(57.8%), and 130(42.2%), with 47.4+16.9, respectively. The greater part was distributed in the older group(p<0.001 by student t-test), suggestive of an increased risk in older group. The average number of nails affected per patient was tending to be higher in frequency close to the thumb, with an equal frequency in six. Thirty-nine patients(28.7%) had all nails affected. The distal band with was 0.5 to 3.0mm averaging 1.0+0.5mm with no difference, in sex. The distal band was pink in 43(31.6%) of the 136 patients with TN, brown in 62(45.6%) and intermediate in color in 13(22,8%). The results of routine laboratory test such as hemogram, eiythrocyte sedimenation rate, liver enzyme, triglyceride, protein, albumin, blood urea nitrogen and creatinine were statistically insignificant between the patients with and without TN.

The purpose of this study was to evaluate the amount and interrelationship of the soft and hard tissue change after mandibular setback surgery in skeletal Class III malocclusion. The sample consisted of 25 adult patient (12 male and 13 female) who had severe anteropostrior skeletal discepancy. These patient had received presurgical orthodontic treatment and surgical treatment which is bilateral sagittal split ramus osteotomy. The presurgical and postsurgical lateral cephalograms were evaluated. The computerized statistical analysis was carried out with SPSS/PC program. The result were as follows: 1. After mandibular bilateral sagittal split ramus osteotomy, lower facial soft tissue horizontal posterior changes were high significance value. but vertical soft tissue changes were low significance value. 2. After mandibular bilateral sagittal split ramus osteotomy, relative upper lip protrusion increased(p<0.01) and relative lower lip protrusion decreased(p<0.01) and lower facial soft tissue thickness increased(p<0.01).

A 17-year-old woman had an extensive nevus comedonicus affecting the left sides of the breast, trunk, axilla, and upper extremity. Her condition was complicated by episodes of re-current cyst formation, secondary infection, and atrophic scars. We performed various therapeutic approaches include topical keratolytic agents, manual extraction of comedones, excision of smaller lesions, and systemic antibiotics but the response was unsatisfactory. We tried systemic isotretinoin and minocycline and the pustulation of the lesions was reduced. Herein we report a rare case of linearly arranged extensive nevus comedonicus.
