Membranous nephropathy (MN) is a glomerular disease characterized by diffuse thickening of the glomerular basement membrane without significant mesangial proliferative change and is usually manifested by the nephrotic syndrome. To evaluate the clinical and pathologic characteristics of this disease in adults, we analyzed 65 patients with primary membranous nephropathy who were diagnosed at Department of Internal Medicine, Chungnam National University Hospital from February 1986 to February 2001. The results are as follows: 1) Of total 96 patients with membranous nephropathy, 67.7% was primary MN. Hepatitis B-associated MN and lupus MN were 22.9%, and 9.4%, respectively. Median duration of follow-up was 35.1 months(0.3∼177) in primary MN, 49.6 months(2.5∼103) in lupus MN, and 35.6 months(0.5∼108) in hepatitis B-associated MN. 2) Mean age of the patients with primary MN at the time of diagnosis(43.3 years) was significantly higher than that of lupus MN(30.4 years) and HBV-associated MN(36.2 years). Male to female ratio of primary MN was 1.03:l. 3) At the time of diagnosis, 89.2% of primary MN was presented with nephrotic syndrome. Twenty seven percent of patients showed hypertension. Hematuria was found in 58.5% of primary MN patients. Azotemia was noted in 3.1 %. 4) Global sclerosis, tubular atrophy and interstitial fibrosis were noted in 39.8, 16.1 and 11.3% of primaty MN, respectively. IgG and C3 were deposited on the glomerular capillary loop in 92.7% and 29% of primary MN patients. There was no significant correlation between the electron microscopic pathologic stage and clinical findings. 5) Of 56 patients with primary MN followed more than 6 months, 50(90.9%) patients were treated with prednisolone, cyclophosphamide or cyclosporin. Complete remission was obtained in 29 patients(51.8%), partial remission in 6 patients(10.7%), and no response in 18 patients(32.1%). Of 6 patients who were not treated with immunosuppressive drugs, 3 patients showed spontaneous complete or partial remission. Three patients who did not show clinical improvement progressed to end-stage renal failure. There were no significant clinical difference including renal pathology at the time of diagnosis between the patients who showed complete or partial remission and patients who did not. In conclusion, it was difficult to predict the long-term prognosis of primary MN at the time of diagnosis, clinically. The response to therapeutic modality would be the most important to predict long-term prognosis of primary MN.

The use of critical pathways for a variety of clinical conditions has grown rapidly in recent years, particularly pathways for patients with acute myocardial infarction. We intend to determine the impact of a clinical pathway on ST-elevation myocardial infarction (STEMI) and to evaluate the efficacy and safety of facilitated percutaneous coronary intervention (PCI) compared with primary PCI. Low risk STEMI patients (ST elevation >0.1mV in more than 2 limb leads or ST elevation >0.2mV in contiguous precordial lead, chest pain lasting more than 30 min without response to nitroglycerin) will be included. All patients will be also treated medically according to critical pathway. STEMI is one of the common diseases in emergency medicine and so it is necessary to establish realistic treatment guidelines. The use of critical pathways will improve the quality of care.

It has been suggested that probiotics could be useful for the prevention of symptomatic relapse in patients with inflammatory bowel disease (IBD). Interleukin (IL)-8 has been well recognized as one of the pro-inflammatory cytokines that could trigger inflammation and epithelial barrier dysfunction. In this study, the anti-inflammatory effects of probiotics were investigated using a human epithelial cell line (HT-29). Probiotics from infant feces and kimchi were tested for their cytotoxicity and effects on adhesion to epithelial cells. The present results show that seven strains could form 70 % adhesion on HT-29. The probiotics used in this study did not affect HT-29 cell viability. To screen anti-inflammatory lactic acid bacteria, HT-29 cells were pretreated with live and heat-killed probiotics, and lipopolysaccharide (LPS) ($1{\mu}g/mL$) was then added to stimulate the cells. The cell culture supernatant was then used to measure IL-8 secretion by ELISA, and the cell pellet was used to determine IL-8 and toll-like receptor (TLR-4) mRNA expression levels by RT-PCR. Some probiotics (KJP421, KDK411, SRK414, E4191, KY21, and KY210) exhibited anti-inflammatory effects through the repression of IL-8 secretion from HT-29 cells. In particular, Lactobacillus salivarius E4191, originating from Egyptian infant feces, not only decreased IL-8 mRNA expression, but also decreased TLR-4 expression. These results indicate that Lactobacillus salivarius E4191 may have a protective effect in intestinal epithelial cells.

During operations, neurosurgeons usually perform multiple temporary occlusions of parental artery, possibly resulting in the neuronal damage. It is generally thought that neuronal damage by cerebral ischemia is associated with extracellular concentrations of the excitatory amino acids. In this study, we measured the dynamics of extracellular glutamate release in 11 vessel occlusion (VO) model to compare between single occlusion and repeated transient occlusions within short interval. Changes in cerebral blood flow were monitored by laser-Doppler flowmetry simultaneously with cortical glutamate level measured by amperometric biosensor. From real time monitoring of glutamate release in 11 VO model, the change of extracellular glutamate level in repeated transient occlusion group was smaller than that of single occlusion group, and the onset time of glutamate release in the second ischemic episode of repeated occlusion group was delayed compared to the first ischemic episode which was similar to that of single 10 min ischemic episode. These results suggested that repeated transient occlusion induces less glutamate release from neuronal cell than single occlusion, and the delayed onset time of glutamate release is attributed to endogeneous protective mechanism of ischemic tolerance.

The small diameter piling is commonly known as the mini pile and its applications have been extensively used in recent years, due to convenience of construction with small rig in the united site, low noise and vibration shock to the near structure. Also the mini pile is applicable to axial loads in bath directions so it can be applied for compressive as well as tensile forces. Although the study about the feature of mini pile method is progressing, it isn't satisfactory yet. Therefore in this study, compared and analyzed bearing capacity and settlement characteristics of mini pile caused by ground condition and pile penetration condition through the analysis of pile static load test in situ and found out the factor that influences most to bearing capacity and settlement by using MINITAB program.
