EXPERIMENTAL EVALUATION OF A IOTA-CARRAGEENANIPOLYVINYLPYRROLIDON GEL AS VITREOUS SUBSTITUTE KOBUCH K. SCHLODERER M. LE-RUPPERT K. UEDA N. GABEL V.P. Deportment of Ophthalmology , Uniwrsttv clinic Regenrburg (G) Pm: A new hydrogel composed ofiota-carrageenan/polyvinylpyrrolidon (icgn/pvp) was tested in rabbit eyes to dctennine its intraocular tolerance and to evaluate its suitability as a vitre...

In this study, we investigated the effect of polyvinylpyrrolidone (PVP) concentration on in vitro and in vivo development of 2 cell stage, vitrified ICR mouse embryos using a cryoprotectant consisting of ethylene glycol (EG) and sucrose. M2 was selected as the basic medium for vitrification and thawing. After equilibration with 4% (v/v) EG at 37 C for 15 min, the embryos were vitrified with 35%...

objective(s) the purpose of the present study was to use the solid dispersion (sd) technique to improve the dissolution rates of indomethacin (imc). materials and methods imc solid dispersions in pvp k30 and isomalt (galen iq 990) were prepared using the solvent evaporation technique and a hot melt method in weight ratios of 2, 10 and 30% (imc:pvp). solid dispersions and physical mixtures were ...

Objective: The objective of the present investigation was to improve dissolution characteristics of EZE, which might offer improved bioavailability. Method: The solid dispersion of Ezetimibe was prepared by Solvent evaporation method by using 1:1, 1:2 and 1:3 ratios of drug and polymers (PVP K-30, Sodium starch glycolate). The tablets were prepared by direct compression method. The compressed t...

The objective of this investigation is to synthesize and investigate zero-valent iron (ZVI) nanoparticles (NPs) for bioremediation applications. ZVI-NPs were fabricated by chemical reduction using a ferrous salt solution with poly(N-vinylpyrrolidone) (PVP), used as stabilizer. synthesis was conducted without ultrasonic treatment. ZVI NPs characterized scanning electron microscopy (SEM), transmi...

The vibrational spectra of platinum nanoparticles (2.4-9 nm) capped with poly(N-vinylpyrrolidone) (PVP) were investigated by deep UV-Raman and FTIR spectroscopy and compared with those of pure PVP. Raman spectra of PVP/Pt show selective enhancement of C=O, C-N, and CH2 vibrational modes attributed to the pyrrolidone ring. Selective enhancement of ring vibrations is attributed both to the resona...

Background: Telmisartan (TEL) is an orally active nonpeptide angiotensin II antagonist drug. The drug acts on a subtype of AT1 receptors, which serves to cope with high blood pressure (hypertension). TEL class Biopharmaceutical Classification System (BCS), that has low solubility in water and permeability. Objectives: This study aims determine the effect formation TEL-PVP K-30 nanoparticles thr...
