Thuya occidentalis is used in popular medicine in the treatment of condyloma and has antibacterial action. Red blood cells (RBC) labeled with technetium-99m (99mTc) are used for several evaluations in nuclear medicine. This labeling depends on a reducing agent, usually stannous ion. Any drug which alters the labeling of the tracer could be expected to modify the disposition of the radiopharmace...

Triple density gradients of metrizamide in plasma (MP) were used to characterize label distribution in human leukocyte preparations incubated with 99mTc tin colloids. Less than 50% of the cell-associated radioactivity was specifically bound to leukocytes when heparinized blood was rotated with stannous fluoride colloid ([Tc]SFC). Labeling efficiency in leukocyte rich plasma (LRP) averaged 44%, ...

Technetium-labelled erythrocytes provide a satisfactory agent for the measurement of red-cell volume with the advantages that there is a low radiation dose and repeated measurements can be readily carried out. A method of labelling red cells using (99)Tc(m)O(4) (-) with a small amount of stannous chloride has been evaluated in 20 patients, and compared with measurements of red-cell volume with ...

A simple deep eutectic solvent based on tin (II) chloride was used as a dual catalyst and environmentally benign reaction medium for an efficient synthesis of 3,4-dihydropyrimidin-2(1H)-one derivatives, from aromatic and aliphatic aldehydes, 1,3-dicarbonyl compounds, and urea in good-to-excellent yields and short reaction time. This simple ammonium deep eutectic solvent, easily synthesized from...

A series of methyl 6-Chloro-2-Substitued-1-[2-(1H-tetrazol-5-yl)-biphenyl-4-ylmethyl]1H-benzoimidazol-5-ylamine were successfully synthesized. Benzimidazoles were prepared by condensation of 4-chloro-o-phenylenediamine with substituted aryl, aldehyde condensation with biphenyl tetrazole group and reduction stannous chloride dihydrate. An insertion-cyclization strategy was involved during synthe...

The distribution of creatinine, one of the toxic guanidine compounds, in various tissues has not been studied in detail by using radiolabeled creatinine. Our objective was to investigate the biodistribution of creatinine labeled with 99m technetium (99mTc) by the stannous (II) chloride method in healthy male Wistar rats. Quality controls were carried out by radio thin layer chromatography, high...

An improved method for determination of Mo by thiocyanate has been standardized by employing thioglycollic acid, instead of currently employed stannous chloride, as reductant of Mo. The method ensures stability of the colored complex in aqueous acidic medium for about 3.5 hours which is otherwise unachievable and the color unstable while using stannous chloride. The method is linear over 0.5 to...

Magos, L., and Cernik, A. A. (1969). Brit. J. industr. Med., 26, 144-149. A rapid method for estimating mercury in undigested biological samples. A method has been developed for estimating mercury in biological samples using an ultraviolet mercury detector, after liberating the mercury from the urine and other biological samples by a simple chemical method. The overall time for one estimation i...
