A colorimetric method for the standardization of heparin preparations.
IT is a fact well known to histologists that certain basic dyes undergo a change of tint when taken up by particular tissue elements, especially cartilage, mucus and the granules of the so-called 'mast cells'. The chemistry of this phenomenon, named 'metachromasia' by Ehrlich, has been studied in some detail by Lison [1935], This investigator concluded that the change of colour in the dye is du...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...

متن کاملStandardization of the method for estimation of ethambutol in pharmaceutical preparations and biological fluid.
A simple column chromatographic method for determination of ethambutol (EMB) in pharmaceutical preparations containing EMB in combination with other anti-TB drugs is presented. The method involved extraction of EMB into an organic solvent, followed by basification and column chromatographic separation on Amberlite CG 50 (100-200 mesh) and elution with suitable eluants and estimation at a wavele...
