PURPOSE: The aim of this study was to investigate treatment results, toxicity and efficacy of hyperfractionated radiation therapy combined with paclitaxel for paraaortic node recurrence in cervix cancer. MATERIALS AND METHODS: Between September 1997 to March 1999, 12 patients with paraaortic node recurrence in cervix cancer who previously received radical or postoperative radiotherapy were treated with hyperfractionated radiation therapy combined with paclitaxel. Of these, 2 patients who irradiated less than 30 Gy were excluded, 10 patients were eligible for this study. Median age was 5 1 years. Initial FlGO stage was 1 stage IB1, 2 stage IIA, 7 stage IIB. For initial treatment, 7 patients received radical radiotherapy and 3 received postoperative radiotherapy. The paraaortic field encompassed the gross recur rent disease with superior margin at T 12, and inferior margin was between L5 and S 1 with gap for previously pelvic radiation field. The radiation field was initially anterior and posterior opposed field followed by both lateral field. The daily dose was 1.2 Gy, twice daily fractions, and total radiotherapy dose was between 50.4 and 60 Gy(median, 58.8 Gy). Concurrent chemotherapy was done with paclitaxel as a radiosensitizer. Dose range was from 20 mg/m to 30 mg/m (median, 25 mg/m'), and cycle of chemotherapy was from 3 to 6 (median, 4.5 cycle). Follow-up period ranged from 3 to 21 months. RESULTS: Interval between initial diagnosis and paraaortic node recurrence was range from 2 to 63 months (median, 8 months). The 1 year overall survival rate and median survival were 75% and 9.5 months, respectively. The 1 year disease free survival rate and median disease free survival were 30% and 3 7 months, respectively. At 1 month after treatment, 4 (40%) achieved a complete response and 6 (63%) experienced a partial response and all patients showed response above the partial response. There was distant metastasis in 6 patients and pelvic node recurrence in 2 patients after paraaortic node irradialion. There was 2 patients with grade 3 to 4 leukopenia and 8 patients with grade 1 to 2 nausea/ vom ting which was usually tolerable with antiemetic drug. There was no chronic complication in abdomen and pelvis during follow up period. CONCLUSION: Hyperfractionated radiation therapy combined with paclitaxel as a radiosensitizer showed high response rate and few complication rate in paraaortic node recurrence in cervix cancer. Therefore, present results suggest that hyperfractionated radiation therapy combined with paclitaxel chemotherapy can be used as optimal treatment modality in this patients.

PURPOSE:Ghrelin is an endogenous ligand of the growth hormone secretagogue receptor, and stomach is the major site of ghrelin secretion. The purpose of this study is to compare the serum ghrelin concentrations between patients with type 2 diabetes mellitus (DM) and normal adults. We studied also whether serum ghrelin levels in the patients with type 2 DM are correlated with body mass index (BMI), serum insulin, lipid profiles, and creatinine levels. METHODS:Forty patients with type 2 DM and forty normal adults were included in this study. We measured heights and weights of the subjects and calculated their BMIs. Blood samples were obtained to measure the ghrelin concentration and their sera were stored at -20degreeC until used. In all subjects, serum ghrelin levels were measured using the commercially available Ghrelin(human) EIA kit. RESULTS:No differences of mean values were detected between the control group and the type 2 diabetic group for age, body weight, BMI, and the levels of serum total cholesterol, triglyceride, HDL cholesterol, and creatinine. But ghrelin level of the type 2 diabetic group (71.1+/-30.5 ng/L) was significantly lower than the control group (139.7+/-36.9 ng/L). In the control group, the ghrelin level showed positive correlation with HDL cholesterol (Pearson's correlation coefficient=0.37, P<0.05). In the diabetic group, the ghrelin level showed weakly positive correlation with insulin concentration. However, there was no significant relationship between serum ghrelin and various parameters in the diabetic patients group. CONCLUSION: In this study, ghrelin concentration in type 2 diabetic patients was lower than that in the control group. In the control group, serum ghrelin concentrations were positively correlated with HDL cholesterol. In the type 2 diabetic group, there was no significant correlation between insulin and ghrelin concentrations.

The formation of cysts in the parameatal area has been reported as rare. A parameatal urethral cyst is a congenital anomaly and has been reported even more rarely in adults. In this study, we present two cases of parameatal urethral cyst and aim to investigate their causes and treatment methods. The extent of cyst spread was assessed using a urethroscope prior to cyst excision, and the excision range was determined accordingly. Complete excision of the cyst was performed as the treatment for parameatal urethral cyst. Both patients were adults who presented with urinary symptoms related to the cyst, necessitating the excision of the congenital parameatal urethral cyst.

PURPOSE: Bone morphogenetic proteins (BMPs) are members of the transforming growth factor-beta family and play an important role in cellular growth. Recent reports suggest that exogenous bone morphogenetic protein-2 (BMP-2) acts as an antiproliferative agent in a variety of cell lines. We will study whether BMP-2 is altered in human colorectal cancer. METHODS: We analyzed 40 colorectal cancer cases and 6 colorectal cancer cell lines by using reverse transcription-polymerase chain reaction (RT-PCR) to determine the expression of BMP-2. RESULTS: Thirteen of 40 colorectal cancers (33%) and 3 of 6 colorectal cancer cell lines (50%) revealed decreased expression of BMP-2. The rates of decreased expression were 0% (0/7), 42.1% (8/19), 28.6% (2/7), 33.3% (2/6), and 100% (1/1) in stages I, II, III, and IV, respectively. Histologically, the rates were 33.3% (2/6), 32.2% (10/21), 50% (1/2), and 0% (0/1) in well-differentiated, moderately-differentiated, poorly-differentiated and mucinous cancers, respectively. As for location, the rates for colon and rectal cancers were 27.8% (5/18) and 36.4% (8/22), respectively. We identified methylation in the CpG island of the BMP-2 gene in 60% of colorectal cancer cells and in 50% of colorectal cancer cell lines. The 13 cases without BMP-2 gene expression showed no significant correlation with clinicopathological factors. Epigenetic silencing through DNA methylation is one of the key steps during carcinogenesis. CONCLUSION: We found, through an analysis using the methylation-specific polymerase chain reaction technique, CpG island methylation of the BMP-2 promoter region in colorectal cancer. Thus, aberrant BMP-2 methylation and the resultant loss of BMP-2 expression may be related to colorectal carcinogenesis.

In the present study, we investigated the anti-inflammatory properties of Eucommia ulmoides Oliv. Bark. (EUE) in lipopolysaccharide (LPS)-stimulated microglial BV-2 cells and found that EUE inhibited LPS-mediated up-regulation of pro-inflammatory response factors. In addition, EUE inhibited the elevated production of pro-inflammatory cytokines, mediators, and reactive oxygen species (ROS) in LPS-stimulated BV-2 microglial cells. Subsequent mechanistic studies revealed that EUE suppressed LPS-induced phosphorylation of mitogen-activated protein kinases (MAPKs), phosphoinositide-3-kinase (PI3K)/Akt, glycogen synthase kinase-3β (GSK-3β), and their downstream transcription factor, nuclear factor-kappa B (NF-κB). EUE also blocked the nuclear translocation of NF-κB and inhibited its binding to DNA. We next demonstrated that EUE induced the nuclear translocation of nuclear factor erythroid 2-related factor 2 (Nrf2) and upregulated heme oxygenase-1 (HO-1) expression. We determined that the significant up-regulation of HO-1 expression by EUE was a consequence of Nrf2 nuclear translocation; furthermore, EUE increased the DNA binding of Nrf2. In contrast, zinc protoporphyrin (ZnPP), a specific HO-1 inhibitor, blocked the ability of EUE to inhibit NO and PGE2 production, indicating the vital role of HO-1. Overall, our results indicate that EUE inhibits pro-inflammatory responses by modulating MAPKs, PI3K/Akt, and GSK-3β, consequently suppressing NF-κB activation and inducing Nrf2-dependent HO-1 activation.

We experienced a case of arteriovenous hemangioma showing Dariers sign on the forehead of a 43-year-old man. He presented with a single, 1 * 1.5cm sized, violaceous, asymptomatic nodule with a history of an intermittent wheal at the lesional site. This skin lesion showed Dariers sign clinically and proliferation of mast cells histopathologically with the punch biopsy specirnen suggesting urticaria pig- mentosa. Howerer, we could diagnose it as a arteriovenous hemangioma on complete excision, as the specimen showed arteriovenous proliferation with increased mast cells in a perivascular pattern. This case showed confusing clinical signs and showed the importance of complete excision for the diagnosis of a small skin tumor especially when a vascular proliferating tumor is suspected.

Visible light can induce damage to the susceptible retina and its injurious effect has been studied morphologically and functionally in detail. In order to evaluate the regenerative processes of the retina damaged by visible light in correlation with the degree of the cellular damage, the rat retina was exposed to blue visible light (400-500nm) for 30, 60 and 120 minutes, and examined electron microscopically, immediately and 1, 2, 3, 4, 5 weeks after the exposure. The results were as follows. The more increased time of exposure by visible light, the more damage to the photoreceptor, and the more delay in the recovery. We observed the recovery of damage was generally slow, and the pigment epithelium necessary for regeneration of discs was not destroyed in spite of long term exposure of visible light.
