The relationship between differential renal uptake of Tc-99m 2-3 dimercaptosuccinic acid (DMSA) and differential renal function was examined in normal and abnormal dogs by correlating Tc-99m DMSA localization with relative renal blood flow and creatining clearance. There was close correlation of fractional Tc-99m DMSA localization with relative renal function.

UNLABELLED 99mTc-DMSA late static planar imaging or SPECT is being used for the investigation of focal acute pyelonephritis (APN), especially in children with urinary tract infection (UTI). Diuretic 99mTc-mercaptoacetyltriglycine (MAG3) dynamic scintirenography has been applied in the evaluation of kidney function and structure, frequently to exclude obstruction. However, in children and adults...

An extract from the marine alga Ulva lactuca was highly osmoprotective in salt-stressed cultures of Sinorhizobium meliloti 102F34. This beneficial activity was due to algal 3-dimethylsulfoniopropionate (DMSP), which was accumulated as a dominant compatible solute and strongly reduced the accumulation of endogenous osmolytes in stressed cells. Synthetic DMSP also acted as a powerful osmoprotecta...

Aim: Superparamagnetic cubic iron oxide nanoparticles (IONPs) were synthesized and functionalized with meso-2,3-dimercaptosuccinic acid (DMSA) as a potential agent for cancer treatment. Methods: Monodisperse IONPs high value of saturation magnetization by thermal decomposition method DMSA via ligand exchange reaction, their cytotoxic effects on HeLa cells investigated. Results: an edge length 2...

INTRODUCTION The aim of this study was to evaluate the accuracy of Technetium Tc 99m dimercaptosuccinic acid (99mTc-DMSA) renal scintigraphy in the diagnosis of urinary tract infection (UTI) in children with suspected infection but with a negative urine culture. MATERIALS AND METHODS The records of all children with suspected or definite diagnosis of UTI presented during a 2-year period were ...

Environmental exposure to arsenic represents a serious challenge to humans and other animals. The aim of the present study was to test the protective effect of antioxidant N-acetylcysteine (NAC) either individually or in combination with a chelating agent, meso-2,3-dimercaptosuccinic acid (DMSA), against sodium arsenite oral toxicity in male rats. Five groups were used: control; arsenic group (...

Purified field bean protease inhibitor (FBPI) was labeled with 99mTcO4- to ascertain its ability to locate tumors in tumor-bearing rat models. The labeling was done with Sn2+ as a reducing agent and the yield was 95%. It was stable for 2 hr at ambient temperature. The biodistribution study of the intravenously injected radiolabeled FBPI in normal Wistar rats at various time intervals showed a r...

BACKGROUND Renal scintigraphy, generally using 99mTc-DMSA, is the accepted reference standard for detection of renal cortical changes. The timing of the test, i.e., whether an acute 99mTc-DMSA scan, a follow-up only or both scans should be performed, however, remains open to discussion. In our study, a six-month follow- up DMSA scan was performed in all the children diagnosed with a first attac...
