Background: The development of uremic symptoms in patients with chronic rena1 failure is related to the decreased blood glutathione levels and RBC antioxidant activities. So, we performed this study to observe the levels of blood glutathione and RBC antioxidant activities in patients with chronic renal failure. Method: The levels of blood glutathione, RBC antioxidants (e.g., superoxdie dismutase, catalase) were examined m twenty one patients with chronic renal failure undergoing maintenance hemodialysis on two to three days interval (CRF group) and fifteen normal person (control group). The CRF group was divided into two groups, high glutathione (HG) group (higher than mean value) and low glutathione (LG) group (lower than normal value). Result: Blood total glutathione levels were significantly lower in CRF group and the ratio of oxidized glutathione (GSSG) were significantly increased compared to control group. In CRF group, catalase activities were significantly increased in LG group compare to HG group. Conclusion: This result suggested that decreased glutathione level probably contribute to increased damage to cell in patient with chronic renal failure.

호흡기 증상과 급성신부전증이 발생된 환자에서 혈액검사, 혈청학적 검사, 방사선학적 검사, ANCA test 및 신생검을 통하여 Wegener씨 육아종증을 경험하였기에 문헌 고찰과 함께 보고하는 바이다. 본질환이 재발하는 경우는 cyclophosphamide에서 azathioprine으로 치료약을 바꾸었을때나 특히 ANCA 반응이 양성으로 지속시 발생한다. Godman과 Churg는 상기도의 괴사성 육아성 병변, 하기도의 괴사성 혈관염, 국한성 신사구체염을 진단의 지표로 삼았다. 특히 상기도 점막의 생검 소견상 괴사성 육아성 혈관염이 보이면 일단 본 증을 의심하고 폐 생검과 신 생검이 필요로 한다. Wegener's Granulomatosis is an uncommon disease which is characterized by granulomatous vasculitis of both lung and kidney. Although the cause is unknown, it's suggesting that disordered immunity with both antibody and cell-mediated tissue damage occurs. The disease affects patients of any age. Characteristic clinical manifestations are diverse but in clude saddle nose deformity, sinusitis, productive coughing, myalgia, fever etc. Characteristic laboratory abnormalities include elevated ESR, neutrophilic leukocytosis, anemia and positive test for ANCA test. Renal biopsy is important for diagnosis. The treatment of choice is a combination of corticosteroid and cytotoxic agent. A53-year-old woman was admitted to our hospital because of productive coughing, short of breathing, oliguria, nausea, and vomiting. Three months ago, she was suffered from general weakness, poor appetite, tingling sensation on extremity, and loosely stool. Twenty days ago, above symptoms were aggravated, she admitted local clinic. Six days ago, because of CBC showed anemia , she was done transfusion. During transfusion, she was developed urticaha then productive coughing, dyspnea, increased serum BUN and creatinine levels. She was transferred to our hospital under the impression of ARF. On the admission, she was chronic ill-looking appearance with pale conjunctiva, tachypnea, dyspnea, and cold sweating. We have checked the patient by CBC, serum and serologic test, X-ray, ANCA test, renal biopsy. With renal biopsy microscopic examination study revealed necrotizing vasculitis, We treated a combination therapy with methyl-PDS and cyclophosphamide. She had a good response. So we report wegener's granulomatosis with the review of relevant literature.

Paraquat (N,N'-dimethy 1-4,4'bipyrydinium : Gramoxone^(R), a widely used herbicide, is extremely toxic to all green plants and many eukaryotic organisms. In human, paraquat intoxication leads to multiple organ failure, it preferentially damages the lung, kidney and liver and may result in death. The participation of superoxide in initiating tissue damage by administration of paraquat is well known in which one electron reduction of paraquat leads to the formation of radical species which react with molecular oxygen to give superoxide. This process initiates immunological changes with the activation of neutrophilic leukocytes, which is related to further production of superoxide. In this experiment, therapeutic effects of cyclophosphamide and dexamethasone on blood cell count, malondialdehyde as a indicator of lipid peroxidation, and antioxidant enzymes levels in the lung, liver and kidney of paraquat intoxicated rats were inbestigated. The WBC count were significantly decreased by combined treatment of cyclophosphamide and dexamethasone in paraquat intoxicated rats at 3 and 5 days but RBC count were not changed. The contents of malondialdehyde were significantly decreased in the lung and Kidney by combined treatment at 10 days after paraquat intoxication. The catalase acitvities were markedly increased in the lung and liver of rats at 10 days after paraquat intoxication, and superoxide dismutase activities showed minimal changes in the lung, liver and kidney of rats by combined treatment. These results suggest that paraquat induced tissue damage in rats can be redeced by combined administration of cyclophosphamide and dexamethasone.
