Venous hemangioma is a vascular tumor that has been reported by such diverse names as; "cirsoid aneurysm", "arteriovenous hemangioma", "acral arteriovenous tumor" according to the author's opinions of its origin and histopathologic classification. It is benign and rarely biopsied, and it is also rarely reported in dermatology literature. We present two cases of venous hemangioma. The first case was a 64-year-old man who was presented with an elliptical dark-red plaque with overlying several grouped papules on the left periorbital area which had been present for 7 years. The second case was a 56-year-old man who was presented with a single red papule on the right postauricular area which had been present for 4 months. Histopathologically, there were a well-circumscribed proliferation of thick-walled muscle-containing blood vessels in the dermis. Intermingled with the thick-walled blood vessels, there were also thin-walled dilated blood vessels. In both cases, the thick-walled blood vessels resembled arteries, but they lacked elastic fibers on the Verhoeff van Gieson stain.

We have expressed GFP in Sf9 and Bm5 cells or Bombyx by larvae by using Ac-Bm hybrid virus capable of replicating in both Bm5 and Sf9 cells. Genomic DNA of Ac-Bm hybrid virus expressing P-galactosidase was cotransfected with baculovirus transfer vector containing GFP gene, pBacPAK-GFP in Sf9 cells. The Ac-Bm hybrid virus harboring GFP was named as Ac-Bm hybrid virus-GFP. The Ac-Bm hybrid virus-GFP-infected insect cells were easily selected by detecting the emission of GFP from each well of cell culture dish on the UV illuminator. GFP produced by Ac-Bm hybrid virus-GFP in Sf9 and Bm5 cells or B. mori larvae was confirmed by SDS-PAGE and Western blot analysis using GFP antibody. In addition, B. mori larvae infected with Ac-Bm hybrid virus-GFP was apparently appeared fluorescence from the whole body at 5 days postinoculation. The fluorescence of GFP from the hemolymph and fat body of B. mori larvae infected with Ac-Bm hybrid virus-GFP was also observed by fluorescence microscope. In conclusion, our results demonstrated that in baculovirus expression vector system, use of Ac-Bm hybrid virus have an additional advantage of expanded host range for producing recombinant proteins.

Heorrhage and infarct-like necrosis of anterior lobe of the pituitary gland is one of the characteristic pathologic findings of the autopsied cases of Korean Hemorrhagic Fever (KHF) patients, but there has been rare reports of hypopituitarism in patients with KHF. Recently we have experienced a patient with hyponatremia who had recovered from KHF. He was admitted to our hospital due to nausea, vomiting, and epigastric discornfort. To determine the function of the anterior pituitary gland, hormonal levels of target galnds and pituitary gland were measured, and combined pituitary stimulation test was performed. ACTH, GH, and prolactin deficiency were confirmed by combined pituitary stimulation test in this patient. There was no evidence of hypothalamic or other pituitary diseases by brain MRI. Our experience shows that KHF can be a cause of hypopituitarism and these findings should alert physicians the possibility of hypopituitarisrn in patients who had recovered from KHF.

OBJECTIVES: It is necessary to examine groups carrying out sexually risky behavior because the prevalence of sexually transmitted diseases (STDs) is high among them. In this study, the prevalence of STDs among homosexuals and sex-buying men in South Korea was investigated, along with their sexual risk factors. METHODS: Men who have sex with men (MSMs, n=108) were recruited in Seoul and Busan by applying the time location sampling method, while sex-buying men (n=118) were recruited from a john school in Gyeonggi province, the suburbs of Seoul. Dependent variables included past or present infection with syphilis, Chlamydia, gonorrhea, and human immunodeficiency virus. Independent variables included health behavior, social support, sexual behavior, and safe sex. RESULTS: It was found that when the MSMs were non-drunk while having sexual intercourse (odds ratio [OR], 0.132), they showed a higher STD infection rate when they had a higher number of anal sex partners (OR, 5.872), rarely used condoms (OR, 1.980), had lower self-efficacy (OR, 0.229), and were more anxious about becoming infected with an STD (OR, 3.723). However, the men who paid for sex showed high STD infections when they had more sex partners (OR, 2.286) and lower education levels (OR, 3.028). CONCLUSIONS: STD infections among the two groups were high when they were engaged with many sex partners and not having protected sex. In other words, there was a gap in risky sex behavior within such groups, which was significantly related to the possibility of developing an STD. Therefore, the preventive intervention against STDs for these groups needs to be expanded to include management of sex behaviors.

AHCC (Active Hexose Correlated Compounds), which was at first extracted from cultured broth of Basidiomycotina, is known to be one of the Biological Response Modifiers (BRM). We examined the protective effects of AHCC on carbon tetrachloride (CCl4) and thioacetamide (TAA)-induced liver injury in mice. The AHCC pretreatment prevented the suppression of several physiological and biochemical parameters in the mice injected with CCl4 or TAA for 5 days. The liver weights and serum ALT and AST levels were increased by CCl4 or TAA, the degree of which was significantly reduced with the AHCC pretreatment. The AHCC pretreatment induced increasing activity of GST (glutathione s-transferase) and showed an increasing tendency of P450 and EROD (ethoxyresorufin o-dealkylation). The AHCC pretreatment also showed negative effects against the suppression of drug metabolizing enzymes, such as P450, EROD, and GST induced by CCl4 or TAA. AHCC pretreatment showed protective effects with significant inhibition of fatty change, inflammation, and necrosis in CCl4 and TAA intoxicated mice liver. The present study suggests that the protective effect of AHCC pretreatment might be related to the protection of liver from the drug induced liver injury in mice model.

A persistent left superior vena cava is the most common anomaly of the superior caval system. Usually the persistent left superior vena cava is connected with the right atrium via the coronary sinus, resulting in no physiologic derangement : however in 7 to 8 percents of the patietns with a persistent left superior vena cava, the anomalous vessel communicates with the left atrim. In the absence of obstruction to the flow from the left atrium to the left ventricle. this anatomic situation usually results in right to left shunting of varying degress. We recently experienced a case of persistent left superior vena cava in a 52-year-old female who complained of chest discomfort, epigastric pain and dyspnea(NYHA functional class II). Cine-angiography showed that the contrast passed from the left SVC through the dilated coronary sinus into right atrium. And right sided SVC was not seen. The patient was treated with conservative measures and discharged with improved condition.

BACKGROUND: The p73 is a recently identified homologue of the tumor suppressor gene, p53, and it has been found to induce apoptosis and inhibit cell proliferation. However, its role in the development of tumors is unclear. This study examined the expression of p73 in patients with non-small cell lung carcinomas (NSCLCs) to determine its clinical significance and association with the expressions of p53, pRb, and mdm2. METHODS: A total of 183 NSCLCs were analyzed immunohistochemically using a tissue microarray. RESULTS: The p73 protein was expressed in the cell nuclei in 156 (85.2%) out of the 183 cases. There was no correlation between the p73 expression and the clinicopathological variables. However, there was a correlation between the p73 expression and the mdm2 and pRb expressions. Multivariate Cox survival analysis identified tumor size and lymph node metastasis to be independent prognostic factors, but the p73 expression was not found to be associated with the patients' survival. CONCLUSIONS: p73 is commonly expressed in NSCLC and it might, in conjunction with pRb and mdm2, be involved in the development of these tumors.

PURPOSE: We evaluated the rate of prostate cancer detection according to the region and number of biopsies in patients with an elevated level of serum prostate-specific antigen (PSA). MATERIALS AND METHODS: Transrectal ultrasound (TRUS) guided prostate biopsies were performed at 12 regions, using the standard sextant, with an additional 6 cores far lateral peripheral zone, in 178 men with an elevated PSA level, and with no suspicious lesions of prostate cancer on digital rectal examination (DRE) and TRUS. We analyzed the rate prostate cancer detection according to the region, number of biopsies, the PSA level, prostate volume and PSA density (PSAD). RESULTS: The rates of cancer detection were 12.9, 11.8 and 7.4% in the 12 core, lateral 6 core and medial 6 core (standard sextant) biopsies, respectively (p<0.05). There were no differences in overall cancer detection rates between 12 core and lateral 6 core plus apex medial 2 core biopsies (12.9%). In men with a PSA level greater than 20ng/ml, no difference in cancer detection was found with the 12 core or either of the 6 core biopsies (positive rate 33.3%). In men with a PSA level over 10ng/ml, a prostate volume less than 49cc or a PSAD greater than 0.15, a lateral 6 core biopsy made no difference to the diagnosis of prostate cancer compared to a 12 core biopsy. CONCLUSIONS: A lateral 6 core biopsy, combined with an apex medial 2 core biopsy, is a more efficient method for the detection of prostate cancer than the standard sextant biopsy in men with an elevated serum PSA level without a suspicious lesion on DRE and TRUS.
