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.

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.

Patterns of branches and distribution of right coronary artery in Korean adult hearts were observed at the viewpoint of newly edited Nomina Anatomica, and the results were as follows. Generally the right aortic sinus had one orifice, but sometimes had two orifices which were related to conal branch. The right coronary artery had mural coronary in 17.5% of cases. In the most of the cases, right coronary artery was dominent, and type 4 was most frequent. Descending septal artery was observed in 17.5% of cases. The atrial branches can be grouped as anterior, posterior and left atrial, and each group was composed of one or two branches when present. In 97.5% of cases, intermediate atrial branch was observed. The sinuatrial nodal artery was originated mostly from right coronary artery. The atrioventriclar branch was observed in 7.5% of cases. The ventricular branches can be grouped as right anterior, right posterior and left posterior, and composed of 3-6, 0-2, and 0-4 branches respectively. Right marginal branch showed great variation, and other branch originated from superiorto to it was found to distribute the apex of the heart. Based on the results, the authors depicts typical arrangement of the rignt coronary artery in Korean.

Human papillomavirus (HPV)infection are now generally accepted as the most important factor for development of uterine cervical cancer and its precursor lesions. With increasing evidences that the HPV E7 encodes for oncoproteins critical for viral replication, host cell immortalization and transformation. Based on the previous reports that the high risk HPV type 16 DNA is frequently detected in specimens from Korean women with cervical cancer and that there is the sequence variation and geographical dependence of HPV 16 E7 gene in preinvasive and invasive cervical lesions, it is crucial to determine the prevalence of HPV 16 variants in uterine cervical lesions of Korean women. This study was performed to identify sequence variations of HPV 16 E7 gene and an association between HPV 16 E7 variants and uterine cervical cancer. The author has determined nucleotide sequences of the E7 gene of HPV 16 isolated from uterine cervical tissues in Korean women. HPV 16 DNAs were detected by the nested PCR in 112 (24.5%) of a total of 457 samples. By direct sequencing of PCR-HPV 16 E7 positive cases, 79 samples (70.5%) showed variant sequences, while the prototype sequence was found in only 33 samples (29.5%). Twenty-three cases (57.5%) of 40 normal cervical samples showed sequence variation. Forty-eight (77.4%) of 62 cervical cancer cases showed sequence diversity from prototype HPV 16 E7 gene. There were four types of sequence variations. A single nucleotide change at position 647 (A-->G) was found in 52 cases (65.8%) of 79 HPV 16 E7 variants. Predicted amino acid change (Asn -->Ser) was found in the HPV 16 E7 oncoproteins at amino acid position at 29. And this KE7-1 variant was commonly detected in the uterine cervical cancer compared to the normal cervix. The second most common variant, detected in 16 cases (20.3%), had three silent mutations at nucleotide positions 732 (T-->C), 789 (T-->C) and 795 (T-->G). The third variant had a single nucleotide change at position 666 (G-->A), and the fourth had a change at position 796 (T-->C). Furthermore, PCR-SSCP clearly showed distinct bands compatible with HPV 16 E7 variants as with the direct-sequencing method. PCR-SSCP was also an effective and reliable tool in detecting HPV 16 E7 variants. This study showed that there were four variant types of HPV 16 E7 in uterine cervical tissues and KE7-1 with corresponding amino acid change was the most commonly detected type in E7 variants of HPV 16 isolated from uterine cervical cancer in Korean women.
