AIMS In the present study we tested the efficacy of N-acetylcysteine (NAC) to minimize nephrotoxic effects of iodine contrast agents in intact rats as well as in 5/6-nephrectomized (5/6-Nx) rats. METHODS Rats were allocated to a group of intact rats (n = 42) and a group of 5/6-Nx rats (n = 42). After 1 month of recovery from surgery, 5/6-Nx rats and intact (sham-operated) animals received eit...
Alagille syndrome (ALGS) is a multisystem autosomal dominant disorder caused by defects in the Notch signaling pathway. The classical criteria for ALGS diagnosis include bile duct paucity on liver biopsy in association with three of the following: Cholestasis, congenital heart disease, vertebral abnormalities, characteristic facial features, and posterior embryotoxon. However, the diagnosis is ...
In our previous study the inclination of nasolacrimal canal in relation to Frankfurt horizontal plane has been analysed on 71 anatomically preparated human skulls by introducing the probe through canal. The results of that study showed that the alpha angle in the frontalplane was greater than 91 degrees in 27% of cases, i.e., nasolacrimal canals descend diverging in relation to the median plane...
Erectile dysfunction is an important problem for men and their families which has an organic cause in about 50 percent of cases. When there is a vasculogenic etiology for this defect, radiologic assessment is unavoidable. Cavernosometry and Cavernosography are ultimate procedures for diagnosis of venous leakage. There is no reliable data about this defects in Iran. The objective of this study w...

زمینه و هدف : ماده حاجب به طور گسترده ای در آنژیوگرافی و مداخلات کرونری استفاده می شود. نفروپاتی ماده حاجب، سومین علت شایع نارسایی حاد کلیه در بیماران بستری در بیمارستان است که بر میزان مرگ و میر و هزینه های مراقبت بهداشتی تأثیر می گذارد. این مطالعه با هدف تعیین اثر پیشگیرانه بی کربنات سدیم بر نفروپاتی ماده حاجب در بیماران پرخطر تحت آنژیوگرافی عروق کرونر انجام شد. روش بررسی: در این مطالعه کارآز...
Abstract Background Postoperative epidural analgesia provides superior postoperative at rest and with activity, compared systemic opioids. However, the impact of on morbidity and/or mortality remains controversial, because sub-optimal reliability catheters that are placed preoperatively used for pain control. The present study technique lumbar epidurography. aims to better understand possible c...
Introduction: To date, gold nanoparticles (GNPs) have been demonstrated to have great potential as contrast agent for CT imaging and therapeutics. This study was designed to evaluate any effect on X-ray attenuation that might result from using GNPs with a variety of size, surface chemistries and shapes. Materials and Methods: Spherical GNPs and gold nanorod...
زمینه و هدف : ماده حاجب به‌طور گسترده‌ای در آنژیوگرافی و مداخلات کرونری استفاده می‌شود. نفروپاتی ماده حاجب، سومین علت شایع نارسایی حاد کلیه در بیماران بستری در بیمارستان است که بر میزان مرگ و میر و هزینه‌های مراقبت بهداشتی تأثیر می‌گذارد. این مطالعه با هدف تعیین اثر پیشگیرانه بی‌کربنات سدیم بر نفروپاتی ماده حاجب در بیماران پرخطر تحت آنژیوگرافی عروق کرونر انجام شد. روش بررسی: در این مطالعه کارآز...
BACKGROUND There is no consensus and a limited evidence base for choice of contrast agents (CA) in angiography. This study evaluated the impact of iohexol and iodixanol CA on fibrinolytic factors (tissue plasminogen activator [t-PA] and plasminogen activator inhibitor-1 [PAI-1]), as well as platelet-monocyte conjugates in cardiac patients undergoing elective angiography in a double-blind, rando...
