We studied the effectiveness with which various charcoal preparations separate free [3H]pteroylglutamate from that complexed with milk folate binder. We tested, in various concentrations, uncoated charcoals and charcoals coated with dextrans of various molecular weights, or with albumin, hemoglubin, or polyvinylpyrrolidone with an average molecular weight of 40 000. Althouth there was some dist...

The influence of montmorillonite (MMT) on the thermal properties polyvinylpyrrolidone (PVP) was studied by differential and thermogravimetric analyses. It found that samples montmorillonite-polyvinylpyrrolidone mixture are characterized higher stability than sample pure PVP. is shown degree increase in temperature beginning destruction depends ratio mixture's components. composition MMT:PVP = 1...

BACKGROUND The objective of this study was to evaluate fluid-bed coating as a new technique to prepare a pellet-based solid self-nanoemulsifying drug delivery system (SNEDDS) using cyclosporin A as a model of a poorly water-soluble drug. METHODS The rationale of this technique was to entrap a Liquid SNEDDS in the matrix of the coating material, polyvinylpyrrolidone K30, by fluid-bed coating. ...

Intravenous infusion of 500 ml of 6% polyvinylpyrrolidone (PVP, average molecular weight 40,000) in isotonic saline solution daily for 2 days induced prompt and significant reductions in serum cholesterol and triglyceride concentrations in eight hyperlipidemic patients. Mean maximal decrements in serum cholesterol and triglyceride were 29% and 28% below control values, respectively, occurring 5...

Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads, which are the main component of the solid part of the cement. In this work beads of poly(methyl methacrylate-co-styrene) were synthesized by suspension polymerization. The objective of this study was t...
