A rapid microtechnic utilizing cellulose acetate membranes for the electrophoretic separation of LDH isoenzymes is described. The use of cellulose acetate for both migration and reagent application representsa relatively inexpensiveand reproducible method which avoids many of the inherent problems associatedwith agar gels. The technic can be used for the analysisof a relatively large number of ...

A short review with 49 references describes the electrospinninng (ES) process for polysaccharides, cellulose and chitosan, and their derivatives, including cellulose acetate and hydroxypropyl cellulose. A majority of applied studies adopted a two step-process, in which the cellulose acetate was used for the first ES process, followed by acetyl group removal to regenerate cellulose thin fibers. ...

The objective of this study was to formulate and evaluate the drug-polymer interaction of mefenamic acid (MA) using two polymers with different characteristics as ethylcellulose (EC) and/or cellulose acetate phthalate (CAP). Microspheres were prepared by the modified emulsion solvent evaporation (MESE). The effect of drug-polymer interaction was studied for each of microspheres. Important param...

Serum containing normal and abnormal levels of alkaline phosphatase activity were assayed for total enzyme activity, then fractionated by electrophoresis on cellulose acetate membranes for 20 mm. The new substrate, phenolphthalein monophosphate, was employed to locate the isoenzymes on the cellulose acetate membranes and to measure their activity by eluting and scanning procedures. The sensitiv...

We describe for the first time a multi-antisera applicator to be used on cellulose acetate membranes with immunoelectrophoresis on a solid support. The new procedure overcomes previous shortcomings of immunoelectrophoresis on cellulose acetate membranes and permits rapid analyses of 11 samples on single “standard”-size membranes with a substantialsaving in antisera, celluloseacetate membranes, ...

A simple, sensitive staining procedure for the localization of leucine aminopeptidase isoenzymes after electrophoretic separation on cellulose acetate membranes is described. Separation of leucine aminopeptidase isoenzymes, using cellulose acetate membranes, does not appear to be a rewarding diagnostic procedure in the investigation of hepatobiliary or pancreatic disorders.

in recent years, great efforts have been devoted to the design of drug delivery systems. many polymeric excipients have been studied in order to make drug release fit the desired profiles. the aim of this work was to design a theophylline oral suspension, as sustained release pharmaceutical preparation in order to decrease the plasma level fluctuations and adverse effects of theophylline. micro...

This study aims to the process of fabricating and characterization nanofibers based on cellulose acetate polymer filled with ceftriaxone ibuprofen using electrospinning method as a model for targeted drug delivery system. Cellulose has been successfully fabricated into ibuprofen. The resulting have an average diameter in range 412.5 – 558.5 nm under conditions process, namely 22 kV voltage, 15 ...
