Lead poisoning has been known as an important disorder that affects individuals through acute, sub-acute and chronic exposure in environmental and occupational settings. This study was conducted to compare the curative role of garlic combined with silymarin versus dimercaptosuccinic acid (DMSA) in decreasing lead induced nephrotoxicity in adult male albino rats. The period of lead intoxication ...

N-(2,3-Dimercaptopropyl) phthalamidic acid (DMPA), meso-dimercaptosuccinic acid (DMSA), and 2,3-dimercapto-1-propanesulfonic acid (DMPS) are dithiol chelating agents with antidotal activity for lead, mercury, arsenic, and other heavy metals. The biliary excretion of these compounds was studied in male Sprague-Dawley rats. After iv administration of DMPA, 72% of the injected dose was recovered i...

introduction: it has been suggested that calculation of differential renal function (drf) using 99mtc-dmsa may lead to overestimation of the function of an obstructed kidney. the aim of this study was to evaluate the effect of diuretic administration on the determination of drf using 99mtc-dmsa scintigraphy in patients with dilated pelvis. methods: thirty three patients, aged from 2 months to 6...

UNLABELLED We collected 149 hair samples at the Baba Farid Centre at Faridkot in Punjab, India to evaluate the trace and toxic metal concentration via ICP-MS. A total of 53 elements were tested. The hair of the children tested showed high values for Ba, Cd, Mn, Pb and U, signifying long-term exposure. Urine baseline testing supported hair analysis findings for all the elements listed above; a D...

Urine is universally recognized as one of the best non-invasive matrices for biomonitoring exposure to a broad range of xenobiotics, including toxic metals. Detection of metal ions in urine has been problematic due to the protein competition and electrode fouling. For direct, simple, and field-deployable monitoring of urinary Pb, electrochemical sensors employing superparamagnetic iron oxide (F...

Renal uptake of 99mTc-DMSA has been quantified by various methods. The aim of this study is to obtain a normal value for 99mTc-DMSA renal uptake calculated by the posterior view method and age variation, and to assess its clinical validity. Scintigrams of 238 children (0-12 years) with 99mTc-DMSA were reviewed. All the children had a clinical history of primary vesicoureteral reflux and/or neur...

Monoisoamyl meso-2,3-dimercaptosuccinate (Mi-ADMS) was found to be superior to meso-2,3-dimercaptosuccinic acid (DMSA) in decreasing the body burden of 203Hg in rats under conditions of early treatment. In this experiment Mi-ADMS was used as late treatment for mercury removal. Albino rats aged 6 weeks and 7-day-old sucklings received a single intraperitoneal injection of 203Hg (as nitrate). Two...

Dimethyl sulfoxide reductase is a heterotrimeric enzyme (DmsABC) localized to the cytoplasmic surface of the inner membrane. Targeting of the DmsA and DmsB catalytic subunits to the membrane requires the membrane targeting and translocation (Mtt) system. The DmsAB dimer is a member of a family of extrinsic, cytoplasmic facing membrane subunits that require Mtt in order to assemble on the membra...

Introduction: The optimal imaging time of a radionuclide scintigraphy is the time at which the organ of interest has the maximum uptake of the injected radionuclide. This study was performed to investigate the maximum uptake time of 99mTc-DMSA in rat renal scan. Methods: Renal scintigraphy was performed with 3 mCi of 99mTc-DMSA. Planar images were acquired every 20 minutes for 8 hours post-inje...

PURPOSE To examine whether (99m)Tc(V)-DMSA could be used as a non-invasive measure of cancer cell proliferation. METHODS Human breast cancer MCF-7, MDA-MB-231 and pII, and prostate cancer PC-3 cell lines were grown to 30, 50 and 100% confluency and pulsed with (99m)Tc(V)-DMSA in media for 60 min at 37°C. DNA synthesis was analysed by quantification of the S phase using flow cytometry, [methyl...
