Coexistence of renal replacement lipomatosis with xanthogranulomatous pyelonephritis 总被引:1,自引:0,他引:1

We report on a case of coexistence of replacement lipomatosis with xanthogranulomatous pyelonephritis (XGP) in the same kidney associated with staghorn calculi. A 63-year-old man was admitted to hospital complaining of a right abdominal mass. Computed tomography (CT) showed renal parenchymal atrophy with extremely increased perirenal fat. Right nephrectomy was performed. Postoperative diagnosis was renal replacement lipomatosis with XGP. Renal replacement lipomatosis and XGP have several similarities in terms of clinical background and CT findings. Sometimes it is difficult to differentiate them from malignant diseases. It is extremely rare that both conditions coexist in the same kidney. To our knowledge, only one such case has been reported. 相似文献

Human renal biopsy specimens (472 cases) from varied kidney diseases, especially minimal glomerular change group and other idiopathic glomerular diseases having nephrotic manifestation of mainly juvenile individuals, showed morphologic evidence of paraarterial deposits of afferent arterioles at the glomerular entrances in more than 50% of examined cases. Because these deposits were often accompanied with concomitant mesangial, intraarterial and subendothelial deposits of afferent arterioles, it was felt that retarded mesangial transport which is ordinarily associated with certain glomerular diseases might be an important factor to produce these particular paraarterial deposits. The referred deposits of minimal glomerular change group cases were thought to predispose the occurrence of focal sclerotic capillary lesions at the vascular poles of glomeruli. The experimental chronic nephrotic rats produced by daily administration of aminonucleoside of puromycin revealed mesangial dysfunction with increased uptake and retarded disposal of secondarily overloaded aggregated human gamma globulin at mesangial areas in glomeruli. Besides, the increased deposits of autologous serum proteins in mesangial areas and arteriolar walls were common findings in those rats, and these deposits were observed to be always preceded to the occurrence of segmental sclerotic changes of glomeruli, which were often associated in the later stage of this experiment.

NHCH3 (X = Gly 1 , Ala 2 , Aib 3 , Leu 4 and D-Ala 5 ), have been investigated by Raman and circular dichroism (CD) spectroscopy. Solid state Raman spectra are consistent with β-turn conformations in all five peptides. These peptides exhibit similar conformations of the disulfide segment in the solid state with a characteristic disulfide stretching frequency at 519 ± 3 cm-1, indicative of a trans-gauche-gauche arrangement about the Cα—Cβ—S—S—Cβ—Cα bonds. The results correlate well with the solid state conformations determined by X-ray diffraction for peptides 3 and 4. CD studies in chloroform and dimethylsulfoxide establish solvent dependent conformational changes for peptides 1, 3 and 5. Disulfide chirality has been derived using the quadrant rule. CD results together with previously reported nuclear magnetic resonance (n.m.r.) data suggest a conformational coupling between the peptide backbone and the disulfide segment. 相似文献

Summary The purpose of this study was to determine the effects of mechanical compression on the palatal mucosa using an experimental palatal base. The palatal base was either pressed onto (stress group) or not pressed onto (fit group) rat palatal mucosa. Blood flow was measured and the animals were sacrificed 6–72 h later for analysis. The expression of heat shock protein 70 (HSP70), vascular endothelial growth factor (VEGF) and proliferation cell nuclear antigen (PCNA) was characterized by immunohistochemical staining. For morphometric analysis, connective tissues were divided into bone side and epithelial side tissues. The ratio of PCNA‐positive cells (PCNA score) was calculated, and the expressions of mRNA encoding HSP70 and VEGF was evaluated. Whereas blood flow in the stress group showed ischaemia, none was found in the fit group. Proliferation cell nuclear antigen scores on the bone side were higher than on the epithelial side in the stress group (P < 0·05). Heat shock protein 70‐ and VEGF‐positive cells were observed under compression conditions, particularly in the periosteum. In the stress group, the expressions of mRNA encoding HSP70 and VEGF were highest at 12 h (P < 0·05). These results suggest that mechanical compression of the palatal plate induces ischaemia, and that cells in the underlying denture‐supporting tissue, which includes the periosteum, synthesize HSP70 and VEGF to maintain homeostasis under these conditions. 相似文献

Aim: Angiotensin II type 1 receptor blockers (ARB) retard the progression of hypertensive diabetic kidney disease. Clinical evidence suggests that the dose of ARB required to correct hypertension is suboptimal for renoprotection evaluated by proteinuria. No systematic, prospective study has yet evaluated separately the effect of increasing doses of ARB on blood pressure and proteinuria.
Methods: Over a period of 8 weeks, the effect of seven constant doses of an ARB, valsartan (4–160 mg/kg per day), on blood pressure and proteinuria taken as a surrogate marker of nephropathy in a hypertensive, type 2 diabetic rat model, the spontaneously hypertensive/NIH-corpulent rat (SHR/NDmcr-cp), was assessed. In this spontaneously hypertensive rat strain, a genetic mutation in the leptin receptor gene is associated with hyperphagia leading to obesity with metabolic syndrome and eventually to nephropathy.
Results: No additional blood pressure lowering was observed above 120 mg/kg per day of valsartan, suggesting that a dose of 80–120 mg/kg per day had a maximal effect. Nevertheless, higher doses of valsartan further reduced proteinuria in a dose-dependent fashion suggesting the absence of a maximal dose. Obesity, hyperglycaemia and hypercholesterolaemia were unaffected but hypertriglyceridaemia was partially corrected at various ARB doses.
Conclusion: ARB improve renoprotection at doses above those required for a maximal effect on blood pressure. The mechanism of the renoprotection obtained at high doses of ARB is yet to be elucidated. 相似文献
