End Stage Renal Disease resulting from complications of the 4 top causes of death including diabetes and hyperpiesia becomes one of the major social problems these days in the context that this disease unaffordably increases the medical cost and decreases the quality of life. For a kidney disease, it is hard to diagnose, cure and recover as there are few subjective symptoms. Therefore, the prevention is very important. In this paper, we propose a method, which checks the abnormal state of the kidney, using the patient's face color and gloss which is employed for diagnosis in the oriental medicine. This method composes of two processes. The first is to acquire the patient's face data applying a polarizing filter and the next is to analyse relations between kidney disease and this data.

Obesity-related glomerulopathy (ORG) is a secondary form of focal and segmental glomerulosclerosis (FSGS) manifesting as proteinuria and progressive renal dysfunction that results from maladaptive glomerular response to increasing adiposity. Reports of ORG progressing to end stage renal diseases in rare in the pediatric population. We report a 9-year-old boy with obesity (body mass index $35\;kg/m^2$) who was diagnosed with ORG presenting with proteinuria. He was diagnosed with obesity-related glomerulopathy based on the laboratory, urinary, and kidney biopsy finding. In spite of treatment with angiotensin- converting enzyme (ACE) inhibitor and/or, angiotensin-receptor blocking agent, the degree or amount of proteinuria increased and renal function declined continuously. His BMI did not decrease and eventually progressed to chronic renal failure. Consequently, obese patients should be monitored for proteinuria, which may be the first manifestation of FSGS, a lesion that may be associated with serious renal sequelae.

We present the case of long-term observation of a patient with chronic kidney disease (CKD) caused by advanced focal segmental glomerulosclerosis (FSGS) resulting from underlying congenital chloride diarrhea (CLD). A 20-year-old woman was admitted for prolonged proteinuria despite conservative treatment for CLD. She was diagnosed with CLD and started taking KCl salt supplementation from the time of birth. Mild proteinuria was first found at 12 years of age, which progressed to moderate proteinuria at 16 years of age. At 16 years of age, CKD stage 2 with FSGS was diagnosed based on the initial assessment of the glomerular filtration rate (GFR) and kidney histology. On admission, we re-assessed her renal function, histology and genetic analysis. GFR had deteriorated to CKD stage 4 and renal histology revealed an advanced FSGS combined with tubulointerstitial fibrosis. A homozygous mutation in the SLC26A3 gene (c.2063-1G>T) was found by diagnostic exome sequencing and may have been inherited from both parents. CLD patients can be more vulnerable to renal injury, which may also cause progression of renal failure. Therefore, even if there is an early diagnosis and adequate salt supplementation, close monitoring of renal function and tailored treatment should be emphasized for renal protection and favorable CLD prognosis.

Purpose : Men are generally more prone to chronic renal disease and progression to end stage renal disease than women. The purpose of this study is to prove the effect of gender and sex hormone on renal fibrosis in mice with unilateral ureteral obstruction (UUO) and to elucidate the specific underlying mechanisms. Methods :We compared the expression of ${\alpha}$-smooth muscle actin (${\alpha}$-SMA) in female and male mice with complete UUO (day 7). After this, we estimated the changes of renal fibrosis in the female mice with oophorectomy and in the female mice with oophorectomy and replacement of $17{\beta}$-estradiol, respectively. Results : The level of ${\alpha}$-SMA in the female kidney with UUO was significantly lower than that in the male kidney with UUO. oophorectomy and replacement of $17{\beta}$-estradiol did not change the expression of angiotensin II type 1 (AT1) receptor in the female kidney with UUO, whereas the expression of angiotensin II type 2 (AT2) receptor was significantly more elevated in the intact female (IF) and the oophorectomized female with estrogen (OF+E) than that in the oophorectomized female (OF). The expressions of inducible nitric oxide synthase (iNOS) in the IF and OF+E mice were significantly more elevated than that in the OF mice, which was similar to the expression of AT2 receptor. Conclusion : The female gender is associated with resistance to renal fibrosis in obstructive uropathy and this gender difference may originate from the existence of $17{\beta}$-estradiol, which has an anti-fibrotic effect via upregulation of the AT2 receptor and iNOS.

Purpose : The hemolytic uremic syndrome (HUS) is characterized by microangiopathic hemolytic anemia thrombocytopenia, and acute renal failure. It is ole of tile most common cause of acute renal failure in children but few reports are available in Korea. Thus we investigated the 23 patients diagnosed as HUS during last 14 years. Method : We retrospectively investigated the etiologic factor, clinical manifestations laboratory findings, treatment modalities, and final outcomes of the patients. Then patients were divided into two groups according to outcome, md comparison was performed. Group A(8) comprised patients who progressed to end-stage renal disease or expired. Group B(15) comprised patients who completely recovered after dialysis treatment. Result The number of patients aged less than 4 years were 17; between 5 and 10 were 4 and more than 10 were 2. The gende ratio was M:F=2 : 1. The etiologic factors were as follows: acute gastroenteritis in 14 patients including 4 bloody diarrhea, upper respiratory tract infection in 7 patients, and 1 patient with herbal mediation. The overall mortality rate was 22$\%$: 2 patients died of US complications, 2 patients died of sepsis, and 1 patient died of pulmonary hemorrhage. Group A (Hb 4.8${\pm}$1.2 g/dL) showed lower value in hemoglobin than group B (Hb 6.3${\pm}$1.7 g/dL) during hospital stay (P< 0.05), And the time interval between tile disease onset and dialysis treatment was significantly longer in group A ($11.9{\pm}9.1\;days\;vs\;2.8{\pm}2.1\;days$) (P< 0.05). Conclusion : Overall mortality rate was 22$\%$. Low hemoglobin value and the prolonged time interval between the disease onset and dialysis treatment were related with poor prognosis. So early diagnosis and appropriate intensive care including dialysis treatment is essential to achieve better outcome in children.

Purpose: This study was conducted to better understand the illness experiences and palliative care needs in community-dwelling persons with cardiometabolic diseases. Methods: This qualitative descriptive study was conducted with 11 patients (and three family members) among 28 patients contacted. Interviews were led by the principal investigator in her office or at participants' home depending on their preference. All interviews were digitally recorded and transcribed by a research assistant. The interviews were analyzed by two independent researchers using a conventional method. Results: Participants' ages ranged from 42 to 82 years (nine men and two women). Three themes were identified: (1) same disease, but different illness experiences; (2) I am in charge of my disease(s); (3) preparation for disease progression. Participants were informed of the name of their disease when they were diagnosed, but not provided with explanation of the diagnosis or meant or how to do self-care to delay the disease progression, which increased the feelings of uncertainty, hopelessness and anxiety. Taking medication was considered to be the primary treatment option and self-care a supplemental one. Advanced care plans were considered when they felt the progression of their disease(s) while refraining from sharing it with their family or health care professionals to save their concerns. All participants were willing to withhold life-sustaining treatment without making any preparation in writing. Conclusion: Education on self-care and advanced care planning should be provided to community-dwelling persons with cardiometabolic diseases. A patient-centered education program needs to be developed for this population.

Onion has been reported to contain various organosulfur compounds which have antibiotic and anticarcinogenic properties and flavonoid like quercetin which is a valuable natural source of antioxidants. Carbohydrates in onion constitute about 80% of dry matter, and the major non-structural carbohydrate of onion bulb is fructo-oligosaccharides, well known as fructan, followed by glucose, fructose, and sucrose. The sugar concentration is associated with dormancy and storage life of onion, occurring as decrease in glucose, fructose and fructan, particularly towards the end of storage. Forced air pre-drying for 15-20 days at room temperature is an essential procedure to reduce freezing injury and sprouting, then onion bulbs can be stored at $0^{\circ}C$ for 6 months to control sprouting and decay. Bacterial soft rot caused by $Erwinia$ and $Pseudomonas$ is the main postharvest disease when the bulbs are infected with the bacteria and stored at room temperature. Browning in sliced onion is due to oxidation of phenolic compounds by polyphenol oxidase and it can be inhibited by citric acid treatment, packing with nitrogen gas, and polyethylene film.

Purpose : Renal cystic diseases comprise a mixed group of heritable, developmental and acquired disorders. Recently the use of imaging modalities such as ultrasonography and radionuclide scanning has increased the detection rate of renal cystic diseases. We studied to review the clinical features and treatment of renal cystic diseases in children. Methods : This study was performed in 95 children with renal cystic diseases in the Department of Pediatrics, Asan Medical Center from October 1989 to June 2001. Results : In 95 patients, there were 55 cases(58.0%) with multicystic dysplastic kidney(MCDK), 19 cases(20.0%) with simple renal cysts, 13 cases(13.7%) with hereditary polycystic kidney diseases( 7 with autosomal recessive type, 5 with autosomal dominant type, 1 with undetermined), 6 cases(6.3%) with renal cysts in tuberous sclerosis and 1 case(1.0%) with medullary cystic disease. All MCDK patients had no renal dysfunction and hypertension during the follow-up period. Three out of 13 with polycystic kidney diseases had progressed to end-stage renal disease during the follow-up period. One case with a simple cyst underwent laparoscopic malsupialization for decompression. Conclusion : Renal cystic diseases have diverse clinicopathologic features and variable prognosis. We emphasize that routine follow-up should be performed to prevent and to detect early treatable complication in renal cystic diseases. Therefore, their natural history and treatment need further investigation and long term follow-up is required.

Membranoproliferative glomerulonephritis type II(MPGN II), also called dense deposit disease, was first described by Berger and Galle in 1963. The diagnosis of MPGN II is based on electron-microscopic finding of an intensely electron-dense substance which replaces the lamina densa of the glomerular basement membrane. Although the etiology and pathogenesis of MPGN II are unknown, it frequently progresses to end-stage renal failure. Typically in MPGN II, hypocomplementemia due to activation of the alternative complement pathway is present. In addition, the association of MPGN II with partial lipodystrophy and complement abnormalities is well documented. The relationship between these associated features and the patient's renal functional outcome is not clear. With respect to the therapy for MPGN II, an alternate-day prednisolone regimen was shown to be effective. Various treatment modalities, including immunosuppression with corticosteroids, cytotoxic drugs and cyclosporin A, anticoagulants and antiplatelet therapies are used, either alone or in combination, with varying degrees of success. The purpose of this paper is to present a case of MPGN II from a 7 years old girl with paroxysmal supraventricular tachycardia(PSVT).
