Polyvinyl pyrrolidone (PVP) in cataract surgery.
Early reformation of the anterior chamber after intraocular surgery is of paramount importance, its absence or delay leading to peripheral anterior synechiae and aphakic glaucoma (Troncoso, 1933; Kronfeld and Grossman, 1941; McLean, I94I; Meyer and Sternberg, 1950). Selinger (1937) injected air after cataract operations to restore the normal curvature of the cornea. He concluded that air preven...
متن کاملNon - Isothermal Depolarization Current Studies in Polyvinyl Pyrrolidone ( PVP ) Foil Electrets
Thermally stimulated depolarization current (TSDC) characteristics of Polyvinyl Pyrrolidone (PVP) electrets are studies in the temperature range 30 to 210 C as functions of the polarizing field (5 to 100kV/cm) and polarizing temperature (40 to 80C). The TSDC spectra comprise two maxima, namely, β and α with their respective locations around 90 C and 172.5 C. These are attributed to dipoleorient...
متن کاملSolute Solvent Interactions of Polyvinyl Pyrrolidone Wrapped Single Walled Carbon Nanotubes (PVP-SWNTs) in Water by Viscometric Studies
Polymer wrapped single walled carbon nanotubes (SWNTs) have been synthesized to improve the solubility of SWNTs in water. The present study deals with experiments so as to highlight the solute solvent interactions during the solubilisation of polyvinyl pyrrolidone wrapped single walled carbon nanotubes (PVP-SWNTs) in water by viscometric methods. Viscosity values of both PVP and PVP-SWNTs have ...
متن کاملAnti-inflammatory effects of silver-polyvinyl pyrrolidone (Ag-PVP) nanoparticles in mouse macrophages infected with live Chlamydia trachomatis
Chlamydia trachomatis is a very common sexually transmissible infection in both developing and developed countries. A hallmark of C. trachomatis infection is the induction of severe inflammatory responses which play critical roles in its pathogenesis. Antibiotics are the only treatment option currently available for controlling C. trachomatis infection; however, they are efficacious only when a...
متن کاملMetoprolol tartrate Containing Glutaraldehyde Cross-linked Chitosan- Polyvinyl pyrrolidone Matrix Transdermal Patch: Preparation and Characterization
The present study was undertaken to develop a suitable transdermal matrix patch of Metoprolol tartrate with different proportions of polyvinyl pyrrolidone (PVP) and chitosan crosslinked with glutaraldehyde (GA). The prepared transdermal patches were subjected to different physicochemical evaluations such as thickness, tensile strength, folding endurance, drug content, swellability, surface pH, ...
