It has been established that ionic surfactants, whether cationic or anionic, provide crystalline molecular complexes stably with various aromatic compounds as additives. Among various additives phenolic compounds are especially favorable for both surfactant species. Other than these additives, cationic surfactants easily provide crystalline molecular complexes with basic materials and even with...

The present study demonstrates the use of mixed co solvency in the enhancement of solubility and estimation of ketoprofen, practically water insoluble dug and thus precludes the use of organic solvents. The selected solubilizers were sodium citrate (15%), PEG 400 (8%) and polyvinyl pyrolidine (7%). Beer’s law was obeyed in the concentration range of 2-20μg/ml at wavelength of 256nm. The solubil...

multiple sclerosis (ms) is an autoimmune disease of central nervous system. since different types of immune cells are involved in ms pathogenesis, in this study we aimed to evaluate serum levels of several immunological components including soluble cd4 (scd4), scd8, scd163, and immunoglobulins as markers of activity of t-cells, macrophages, and b-cells in different types of ms. serum levels of ...
