Background: We report a rare case of CAPD peritonitis caused by Ochrobacterium anthropi. Introductions: Among the continuous ambulatory peritoneal dialysis(CAPD) patients, peritonitis is one of the most commonly taken complications, and also the general cause of dialytic modality exchange to hemodialysis. Usual pathogens of CAPD peritonitis may be bacteria, fungi, mycobacteria. Coagulase negative staphylococci, S. aureus, campylobacter, pseudomonas are common reported pathogens among the bacteria, of CAPD peritonitis cases, meanwhile candida is among fungi. Ochrobacterium anthropi is one species of Brucellaceae, which is rare pathogen of human disease. Case (Methods and results): 73 years old female, who was on CAPD due to diabetic end stage renal disease visited Kyung-Hee University hospital with intermittent abdominal pain. Body fi uid analysis showed increased white blood cell(WBC) count of 26,750/mm3 with her peritoneal fi uid. Culture study with peritoneal fi uid suggested O. anthropi, and DNA sequencing with PCR was consistent with O. anthropi. Intraperitoneal ceftazidime and cefazolin were administrated as empirical antibiotics. Ceftazidime resistance was noted with the result of antibiotics sensitivity test at 7th day of hospitalization, and antibiotics were changed into intraperitoneal gentamicin, which showed sensitivity to the pathogen. CAPD catheter removal and antibiotics re-exchange into imipenem and cefazolin, which were other sensitive antibiotics by the sensitivity test, were done since clinical manifestation and peritoneal fi uid WBC count was repeatedly improved and aggravated. The patient discharged with improved lab test results and resolving clinical symptoms afterward. Conclusions: We presentators report rare case of CAPD peritonitis with pathogen of O. anthropi. The pathogen of the case confi rmed by classical microbiologic, and molecular biologic Methods: The patient was unable to treat only with antibiotics, thus CAPD catheter, which might be act as colonizing source, was removed, and the disease resolved.

Objective: Several factors contribute to the development of hypertension in patients with IgA nephropathy (IgAN). This study was conducted to find the relationships between baseline blood pressure (BP) and clinico-pathological findings in patients with IgAN and normal renal function. Design and Method: Clinico-pathological findings were analyzed in a total of 163 patients with IgAN and serum creatinine ￡ 1.1 mg/dL from The Kyung-Hee Cohort of Glomerulonephritis. The glomerular surface area (GSA) was determined using imaging analysis software. The serum and urine angiotensinogen (AGT) concentrations were measured using human ELISA kits.?Results: Mean serum creatinine concentration was 0.86 (0.5~1.1) mg/dL. Systolic BP was ≥ 130 mmHg in 72 patients (44%) and ≥ 140 mmHg in 42 (26%). Patients with systolic BP ≥ 130 mmHg as compared with those <130 mmHg had higher GSA and tubulointerstitial fibrosis and showed worse follow-up clinical findings: higher concentrations of serum creatinine, larger amount of proteinuria and lower levels of GFR. Systolic BP was positively correlated with age, baseline and follow-up proteinuria, serum uric acid concentrations and IgM deposit and negatively with follow-up GFR and the slope of change in 1/serum creatinine for 2 years, while it has no significant relationships with serum and urine AGT and 24 hour urinary sodium excretion. Conclusions: This study showed that systolic BP was associated with renal progression and pathological findings, glomerulomegaly and tubulointerstitial fibrosis, in patients with IgAN.

N/A Objectives: Renal transplantation is a major therapeutic advance for patients with chronic renal failure. But recipients of renal transplantation are prone to infection with both common and unusual organisms. And infectious diseases remain a major cause of morbidity and mortality in renal transplant recipients. This study was to analyze the infections in renal transplant recipients; its occurrence according to sites and organisms; comparison among immunosuppressive agents; prognostic differences of urinary tract infections(UTI) between those developed during 1 month after transplantation and those not developed; graft outcome; and patients mortality. Mothods: 181 renal transplant recipients were examined. They received renal transplantion between january 1979 and December 1992 at the Kyung-Hee University Hospital. 158 of them received transplantation from living-related donors, 22 from living-unrelated donors, and 1 from cadaver donor. Their age at the time of transplantation ranged from 14 to 66 years(mean 35.6 years), and the male to female ratio was 2.3: 1. The observation period ranged from 1 to 144 months(41.26±31.71, mean±S. D.). Results: 1) 110 recipients(60.7% of total) had 232 episodes of infectious complications whereas 71(39.3% of total) had no infectious episodes. About half of infectious episodes(128 episodes, 55.2% ) occurred during 1 month after transplantation. 2) The most common site of infection was urinary tract(138 episodes, 59.2%) whth the next sites coming in this order, bacteremia(32 episodes, 13.8%), pulmonary(21 episodes, 9.1%), and skin(21 episodes, 9.1%). 3) The causative organisms of UTI ranked in this order E. coli 21.7%, staphylococcus spp 14.5%, and pseudomonas spp 13.0%. 4) The causative organisms of bacteremia ranked in this order E. coli 34.4% salmonella spp 18.8%, pseudomonas spp 12.5 %, and staphylococcus spp 12.5%. 5) There was no significant differences of infectious episodes among immunosuppressive regimens. 6) Early UTI group(UTI occurred during 1 month after transplantation) recorded significantly higher incidence of urinary tract infections after 1 month that followed than non-UTI group. But there was no differences between two groups on graft and patients outcome. 7) The major cause of death was life-threatening infections(63.2 %). Conclusion: Most infections due to various organisms may occur during 1 month after transplantation. And still they constitute a major cause of death in renal transplant recipients.

Peanut allergy is a major cause of food-induced anaphylaxis and subsequent fatality. Food allergies are becoming an increasingly important global health issue. This study was undertaken to verify the effects of peanut sprout extract (PNSE) on the inhibition of allergic and anaphylactic responses using a peanut (PN)-immunized food allergy mouse model. Fresh peanut sprouts were germinated for 0, 3, 5, and 7 days using mature peanuts. Mice were then sensitized to cholera toxin plus PNE or PNSE by intragastric administration on days 0 and 7, and were then challenged with PNE or PNSE on days 21 and 35. After 5 weeks, we examined the mucosal mast cell degranulation, ear swelling, and systemic anaphylaxis stimulated by PNE extract, in comparison with PNSE. Subsequently, Ara h1, a biomarker of PNE allergy; serum levels; and Th1/Th2 cytokine production in supernatants of cultured splenocytes were measured. PNSE treatment significantly attenuated the secretion of anti-Ara h1 antibody, mucosal mast cell degranulation, degree of systemic anaphylaxis, and ear swelling and increased the production of IFN-γ and IL-10, with a decrease in IL-4 secretion. The results of this study show that the allergenicity of PNE could be reduced by germination, which caused downregulation of Th2 lymphocyte activity, systemic anaphylactic response, and mast cell-mediated ear swelling in PNE-sensitized mice.

본 연구에서는 고추씨 에탄올추출물이 콜레스테롤 흡착능 및 UDP-glucuronyl transferase 활성에 미치는 영향을 관찰하였다. In vitro 콜레스테롤 흡착능에서는 대조군에 비해 고추씨 에탄올추출물 모든 농도에서 유의적으로 증가하였다. In vivo에서 실험동물은 체중 100±10 g 내외의 Sprague-Dawley계 수컷 흰쥐를 사용하였으며, 실험군은 정상식이를 공급한 정상군과 고지방ㆍ고콜레스테롤 식이 실험군으로 나누고 고지방ㆍ고콜레스테롤 실험군을 다시 고추씨 에탄올추출물을 공급하지 않은 군(HF groups), 0.1% 공급한 군(HEA group), 0.2%을 공급한 군(HEB group) 및 0.5%을 공급한 군(HEC group), 5군으로 나누고 각 군당 8마리씩 3주간 사육하였다. 체중증가량은 정상군에 비해 HF 군에서 유의적으로 증가하였고 고추씨 에탄올추출물을 공급한 모든 군에서 HF 군에 감소하였으나 유의적인 차이는 없었다. 식이효율은 고추씨 에탄올추출물을 각각 0.1%, 0.2% 및 0.5% 공급한 군에서는 HF군에 비해 유의적이지는 않았지만 감소하는 경향을 보였다. 간조직의 총콜레스테롤 및 중성지질 함량은 정상군에 비해 HF 군에서 유의적으로 증가하였고 HF 군에 비해 HEA, HEB 및 HEC군에서는 유의적이지는 않았지만 다소 감소하는 경향을 나타내었다. UDP-glucuronyl transferase 활성에서는 정상군에 비해 HF 군에서 증가되었고, 고추씨 에탄올추출물 공급군인 HEC 군에서는 HF 군에 비해 유의적으로 증가되어 가장 높은 활성을 나타내었다. 혈청중의 총콜레스테롤 및 중성지방 농도는 정상군에 비해 HF 군에서 유의적으로 증가하였고, HEA, HEB 및 HEC 군에서 HF 군에 비해 감소하였다. HDL-콜레스테롤은 정상군에 비해 HF 군에서 유의적으로 감소하였으나 HEA, HEB 및 HEC 군에서는 HF 군에 비해 정상군 수준으로 증가하는 경향을 보였다. 반면, LDL-콜레스테롤은 HF 군에서 정상군에 비해 유의적으로 증가하였으나 HEA, HEB 및 HEC 군에서는 모두 유의적 감소를 나타내었다. 대변중의 총콜레스테롤 함량은 정상군에 비해 HF 군에서 유의적으로 증가하였고 HF 군에 비해 특히 고추씨 에탄올추출물 공급군 HEB 군 및 HEC 군에서 증가하는 경향을 나타내었으나 유의적인 차이는 없었다. 중성지질 함량은 정상군에 비해 HF 군에서는 유의적이지는 않았지만 증가되었고, 고추씨 에탄올추출물을 공급한 HEB군 및 HEC 군에서 HF 군에 비해 다소 증가하는 경향을 나타내었다. 따라서 고추씨 에탄올 추출물은 콜레스테롤 흡착능에서 효과적으로 작용하였으며 고지방?고콜레스테롤 식이 흰쥐의 UDP-glucuronyl transferase 활성 및 지질대사에 효과적으로 작용하였음을 규명하였다. The purpose of this study was to investigate the effects of ethanol extracts from red pepper seeds on cholesterol adsorption capacity and UDP-glucuronyl transferase activity. In vitro cholesterol adsorption capacity of 2%, 5% and 10% ethanol extracts from red pepper seed groups were significantly higher than that of the control group. Sprague-Dawley strain male rats weighing 100±10 g were randomly assigned to one normal diet N group and experimental groups fed high fat and high cholesterol diet, which were divided into HF (0.0%), HEA (0.1%), HEB (0.2%), and HEC (0.5%) groups according to the amount of ethanol extracts from red pepper seeds added to their basal diet. The body weight gain in the HF group was higher than that in the N group, and those in the HEA, HEB and HEC groups were lower than that in the HF group However, there were no statistically significant differences among the all the groups. The hepatic triglyceride and total cholesterol contents in the N group was significantly lower than that in the HF group, and those in the HEA, HEB and HEC groups were lower than that in the HF group. The hepatic UDP-glucuronyl transferase activity in the N group was lower than that of the HF group and those in the HEA, HEB and HEC groups were lower than that of the HF group. The serum total cholesterol and triglyceride contents of the HF group were significantly higher than that of the N group, and those of the HEA, HEB and HEC groups were lower than that of the HF group. The serum HDL-cholesterol contents in all groups supplemented with the ethanol extracts from red pepper seeds were significantly higher than that of the HF group. The serum LDL-cholesterol contents of the HF group were significantly higher than that of the N group, and those of the HEA, HEB and HEC groups were lower than that of the HF group. The fecal total cholesterol contents were significantly higher in the HF group compared to the N group, and those of the HEB and HEC groups were lower than that of the HF group. The fecal triglyceride contents in the N group was higher than that of the HF group, and those of the HEA, HEB and HEC groups were lower than that of the HF group. This study suggested that the ethanol extracts from red pepper seeds have powerful health benefits by the UDP-glucuronyl transferase activity and lipid metabolism.
