A variety of malignant neoplasms have been shown to induce neovascularization, and in some cases the degree of vascularization appears to correlate with an aggressive behavior and risk of metastasis. We compared the degree of vascularization in 11 benign and 33 cancerous lesions of the cervix. The microvessels were identified by immunohistochemistry using antibody to Factor VIII-related antigen in 44 hystrectomy specimens. Three highly vascularized microscopic fields were selected and counted the number of microvessels in 400 magnification. The proportion of the endothelial cell area was also quantified by using the CAS 200 image analysis system. All 33 cases of carcinomas demonstrated a significantly higher microvessel count and an endothelial cell area than those of the benign lesions (p<0.01). There were no significant difference in microvessel count and endothelial cell area among carcinoma in situ, microinvasive carcinoma and invasive carcinoma (p>0.05). Microvessel count and an endothelial cell area in invasive cancers were not correlated with tumor size, depth of invasion, or histologic type (p>0.05).This study showed cervical cancer induces neovascularization in an early stage but it is difficult to predict prognosis and metastasis with microvessel count and an endothelial cell area.

In order to evaluate the role of cytopathologic diagnosis of sputum, bronchial washing and bronchial brushing in the diagnosis of lung cancer, we performed this study. The patients included in this study had undergone sputum, bronchial washing and brushing cytology over the 20-month period of 1985 through 1987. The total number of specimens was 5,495 of 2,242 patients, including 4,830 sputa and 665 bronchial washing and brushings. The average number of sputa and bronchial washings and brushings per case was 2.4 and 1.2 respectively. Among them, about 10% were unsatisfactory specimen, and three-fourths were negative specimens. In sputum cytology, the diagnosis of "atypical cells" was given to 3%, "suspicious for malignancy" was given to 1%, and "malignancy" was given to 13%. In bronchial washing and brushing cytology, the diagnosis of "atypical cells", "suspicious for malignancy" and malignancy" was given to 6%, 3%, and 20% respectively. The cases diagnosed as "atypical cells" in cytology were actually malignancy in 95% and 84.8% of sputum and bronchial washing and brushings respectively, and the "suspicious for malignancy" were actually malignancy in 100% in both methods. The detection rates of malignancy were 50.4% and 55.2% in sputum and bronchial washing and brushing respectively, and the specificity was 100% in both methods. The accuracy of cell typing was 92% in sputum and 89.7% in bronchial washing and brushing.

Congenital pulmonary lymphangiectasis is a rare cause of severe respiratory distress in the newborn period and most of these patient die, usually within the first 24 hours of life. The light microscopic characteristics of the lungs are a network of partly tubular, partly cystically enlarged lymph vessels within large areas of connective tissue and they have thin wall lined by endothelium. Also congenital pulmonary lymphangiectasis is closely associated with cardiovascular malformation, and most frequently occurs in the clinical setting of congenital heart disease with or without pulmonary venous obstruction(total anomalous venous return, atresia of large pulmonary veins) The authors describe three typical cases of congenital pulmonary lymphangiectasis.

BACKGROUND: There are a few methods, including primary intention, deleyed primary closure and secondary intention, to irpair several types of defects. But commonly-used primary intentional repair of a defect after surgical removal of a skin cancer by graft, flap or simple closure has several limitations such as the need of a skillful technique and various complications. OBJECTIVE: We undertook a secondary intention using occlusive dressing with a polyurethane film after skin cancer surgery instead of a primary repair and evaluated its efficacy, particularly in points of simplicity and safety, and cosmetic results. METHODS: We randomly chose 14 cases of skin cancers in 13 patients who had undergone simple surgical excision or Mohs micrographic surgery and then undertook secondary intention with polyurethane film after informed consent. Postsurgical wound care included cleansing with normal saline or boric acid, then covering the defect with antibiotic ointment, gauze and film a at regular intervals.

Standard plaque assay using agarose-overlay has long been used for titration of many infectious virus particle. Plaque assay for the titration of varicella-zoster virus and its live vaccine requires three intermittent agarose overlay to visualize plaques. Overall procedure of the assay takes at least nine days from virus inoculation and microbe contamination including fungi is frequently accompanied during incubation period. We studied whether an immunofocus assay in conjunction with peroxidase-mediated immunohistochemical reaction may replace the standard plaque assay for the virus titration by comparing the two methods. A linear relationship was observed between number of foci and virus dilution. The number of foci in a given dilution of virus appeared a little higher than counted plaques formed in standard plaque assay. Independent titration results obtained from two assay methods for a given dilution of virus demonstrated a strong correlation (r2=0.99). Foci of virus infected cells as revealed by the enzyme reaction could be counted either 4 days post-infection (p.i.) under low magnification (40X) microscopy, or 6 days p.i. by naked eye observation. Larger size of cell cuture plate, virus adsorption at 35 degrees C, and 10% FBS in diluent appeared to be better conditions for the assay. Immunofocus assay will be an effective and dependable titration method for varicella-zoster virus and its live vaccine in place of the standard plaque assay in respect to accuracy, costs, and experimental convenience.

OBJECTIVE: This study was performed to evaluate the usefulness of New cervicography by comparing cervicographic finding with Papanicolaou smear and result of colposcopically directed biopsy. METHODS: This study group consisted of 189 patients who visited the Department of Obstetrics and Gynecology, Chung-Ang University Pildong Hospital from September 1998 to August 1999. All women simultaneously underwent Papanicolaou smear and New cervicography. If either method was positive, the patient was referred for colposcopically directed biopsy. RESULTS: The New cervicography was significantly more sensitive than the Papanicolaou smear(92.2% vs 60.8%, p<0.01), whereas the Papanicolaou smear was significantly more specific than the New cervicography(99.3% vs 75.0%, p<0.05). The false positive rate of New cervicography was 75%, significantly higher than 0.7% of Papanicolaou smear. There was no significant difference between the negative predictive value of cervicography and Papanicolaou smear. When New cervicography and Papanicolaou smear were used together, the sensitivity was significantly higher than Papanicolaou smear used alone(98.1% vs 60.8%, p<0.01) and false negative rate was significantly lower than Papanicolaou smear(1.9% vs 39.2%, p<0.01). However the specificity, positive predictive value of the combined test were lower than Papanicolaou smear. CONCLUSION: Cervicography is one of the Papanicolaou smear adjunctive tests and a useful method to detect cervical cancer. Our study confirms the previously suspected low sensitivity of Papanicolaou smear and demonstrate that cervicography is more sensitive than Papanicolaou smear and less specific. From the above results, when New cervicography and Papanicolaou smear were used together, the detection rate of cervical cancer will be increased more easily since the cases missed by one method may be picked up by another.
