“Background: Peritubular endothelium plays a key role in the development and progression of diabetic and nondiabetic chronic kidney disease. Renal injury in disorders of glucose metabolism may appear as early as in the stage of impaired glucose tolerance (IGT) and is accelerated by hypertension. The aim of our study was to investigate renal histology in rats with hypertension and IGT, with special emphasis on the peritubular endothelium.
Methods: Hypertension and IGT (H/IGT) were provoked in adult male Wistar rats by bilateral administration of methylglyoxal into the ventromedial selleck screening library hypothalamus. Immunohistochemistry
with anti-renin and anti-imidazolone antibodies and immunoelectron microscopy with anti-renin antibody were performed.
Results: H/IGT rats showed tubulointerstitial fibrosis as well as renin and imidazolone staining in the papillary region. The patterns of immunostaining for renin and imidazolone were similar to that of endothelium. On electron microscopy, peritubular capillary endothelial cells and to a less extent, tubular epithelial NU7441 order cells showed renin positivity.
Discussion: Impaired glucose tolerance complicated with hypertension leads to tubulointerstitial fibrosis in rat kidney. Imidazolone deposition and renin production in peritubular capillary endothelial cells may play a role in the development of tubulointerstitial fibrosis.”
“Objective: To evaluate the feasibility,
efficacy and safety of ultrasound-accelerated catheter-directed thrombolysis (UACDT) in the delayed treatment of lower extremity deep venous thrombosis (DVT).
Design: Twelve patients with unilateral iliofemoral or femoropopliteal DVT (mean symptom duration 92 +/- 44 days) were prospectively investigated.
Method: UACDT was performed using recombinant human tissue plasminogen activator delivered using the EKOS EkoSonic system. Stents were deployed if indicated by post-procedure venography. Follow-up comprised weekly duplex ultrasound for 1 month and monthly thereafter.
Results: Successful thrombolysis occurred in 11/12 limbs (92%; complete 6/12, partial 5/12) after GDC-0941 supplier a mean infusion time of 26 +/- 7 hours. 2/12 patients required angioplasty and stent insertion. At a mean follow-up of 9 (6-15) months, 10/11 (91%) veins were patent whereas 1/11 re-occluded at 2 months (patient with protein-C deficiency). 2/11 limbs developed symptoms/signs of post-thrombotic syndrome and 3/11 had developed deep vein reflux (duplex ultrasound). 2/12 patients experienced pen-catheter bleeding but no major hemorrhage or symptomatic pulmonary embolism occurred.
Conclusions: This preliminary evidence suggests that UACDT may be a safe and effective option for the delayed treatment of lower limb DVT. (C) 2013 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.
