Purpose: The purpose of this study was to evaluate the utility of Gd-DTPA-enhanced dynamic MRI (DMRI) in earlydiagnosis and the assessment of disease processing in experimentally-induced crescentic glomerulonephritis (CGN)in rabbits. Materials and Methods: In six rabbits, CGN was induced by an injection of anti-glomerular basementmembrane Ab. A time-signal intensity curve (TSC) was obtained from DMRI on the day before, and at 1, 4, 7, 15, 45and 113 days after the induction of CGN. Sequential renal biopsies and blood sampling (serum creatinine) wereperformed on the same days, and the results of DMRI and TSC, were compared. Results: In normal kidneys, sequentialDMRI demonstrated the intratubular passage of Gd-DTPA as an inwardly migrating, thin, dark, band pattern. On days1 and 4, the thin dark band appeared but was poorly defined and TSC revealed a delay in peak time. On days 7 and15, movement of the band was seen to be weak and slow, and there was no centripetal migration. The maximal signalintensity of TSC was delayed, and the curves declined very slowly. On days 45 and 113, the dark band pattern wasvery weak and slow, and again there was no centripetal migration. Conclusion: GD-DTPA-enhanced DMRI may be ofvalue in the evaluation of disease processing and the severity of CGN.

발작성 야간혈색소뇨증은 매우 드문 용혈성 빈혈로 MR 소견이 보고되기전까지는 특징적인 방사선학적 소견에 대하여 별로 알려져 있지 않았다. 그러나 최근 MR과 CT의 특 징적 소견이 외국 문헌에는 보고된 바 있으나 국내 보고는 없어 MR 및 CT 소견을 보고한 다. 암적색 혈뇨와 만성 빈혈증상으로 반복 수혈후 발작성 야간혈색소뇨증으로 진단된 61세 여자 환자로 복부 MR의 T1, T2 강조영상에서 신피질은 신수질과 비교해 특징적인 저신호 강도를 보였으며 이러한 저신호강도 부위는 조영제를 사용치 않은 CT에서 신피질의 증가된 음영과 일치하였다. 다량 수혈에 의한 혈철증으로 간은 MR에서 저신호강도를 보였고 비장 은 정상이었으며 또한 조영전 CT 상 비장과 비교해 증가된 간 음영을 볼 수 있었다. Paroxysmal nocturnal hemoglobinuria(PNH) is a rare, acquired disease involving multiple hematopoietic celllines. Characteristics of PNH are intrinsic hemolytic anemia, iron deficiency anemia and venous thrombosis. Wereport a case of PNH with characterostoc MR and CT findings. The signal intensity of renal cortex was lower thanthat of medulla on both T1- and T2- weighted MR imaging. On T2 weighted MR images, the liver showed very lowsignal intensity but the signal intensity of the spleen was normal. On precontrast CT the attenuation of renalcortex was higher than that of renal medulla and the attenuation of liver was higher than that of the spleen.These findings of MR imaging and CT were the result from the deposition of hemosiderin in the cells of proximalconvoluted tubules and transfusional hemosiderosis of liver.

Background : The aim of this study was to characterize the nature and elucidate the pathogenesis of hemodialysis ascites(HA), especially with regard to the levels of Serum Ascites Albumin radient(SAAG) and the degrees of hemodialysis adequacy(Kt/Vurea). Methods : In the study group, seven cases of HA which had developed in 6 patients from Feb. 1997 through July 1998 were included. In the control group, 24 cases which had not developed HA were included. The study design was a retrospective. Analysis of ascites on WBC, total protein and albumin, cytology, ADA(Adenosine deaminase), osmolality, SAAG and routine work-up were performed in HA group. Serum total protein and albumin, C-reactive protein(CRP), osmolality, and routine liver function test were also checked. Kt/Vurea and weekly Kt/Vurea were calculated in both group. In statistical analyses, t-test and chi-square test were used.Results : Mean SAAG of HA was >1.1(1.49±0.40) gm/dL, and mean concentration of total protein of HA was >2.5(4.26±0.58) gm/dL. The mean of weekly Kt/Vurea of patients with HA(2.61±0.85) was significantly lower than that of patients without HA(3.48±0.90)(p<0.05). Positive ratio of CRP in patients with HA was higher than that of patients without HA(p<0.05). Mean concentration of serum total protein was significantly higher in patients with HA than that of patients without HA but with comparable weekly Kt/Vurea levels(p<0.05).Conclusion : It is regarded that the nature of HA is an exudate having high SAAG over 1.1 gm/dL. Low weekly Kt/Vurea is suggested as a cause of HA. Chronic inflammation was also regarded as an important factor causing HA.(Korean J Med 59:283-289, 2000)

N/A Recently, much attention has been focused on the role of calcium in mediating or propagating ischemic cell injury. Modifying alterations in cell calcium redistribution or cellular calcium influx with a variety of agents have been beneficial in ameliorating the degree of cell injury in a number of experimental settings. But studies on animal models about ischemic acute renal failure (ARF) produced either by infusion of vasoconstrictors or by interrupting renal artery blood flow have provided conflicting results. The purpose of this study was to evaluate the effect of calcium entry blockers in an ischemic ARF model by the renal artery clamp in rats. Nine cats were anesthetized with pentobarbital sodium (40mg/kg, I.M,) and a tracheostomy, an IV line and a urinary catheter were placed in position. Temperature was maintained at 37.5 degrees C. By an abdominal approach, both renal arteries were isolated. Four cats were used as controls and received saline for 2 hours before bilateral renal artery clamping. Another five cats were treated with verapamil (5㎍/kg/min.) systemically for 2 hours before bilateral renal artery clamping. All nine cats underwent 1 hour of renal artery clamp followed by 3 hours of reperfusion and hydration with saline. Before clamping and after reperfusion, blood and urine were sampled for creatinine, Na and K, and urine volume was measured. The results were as follows: In the control group, the serum creatinine level was 1.28㎍0.33㎎/dl before clamping and increased to 1.63±0.73㎎/dl after clamping; in the experimental group, the serum creatinine level was 1.20±0.33㎎/dl before clamping and increased to 1.75±0.50㎎/dl after clamping. In the control group, the Ccr value was 13.08±9.25ml/min before clamping and decreased to 0.41±0.22ml/min after clamping; in the experimental group, the Ccr value was 6.24±6.18ml/min before clamping and decreased to 0.14±0.09ml/min after clamping. But these results were not significant statistically. Our results suggested that systemic pretreatment with a calcium entry blocker (verapamil) may be ineffective in an ischemic ARF model by renal artery clamping in cats.
