Hydrogen peroxide is an important mild oxidant which is widely used in various applications including remediation of waste waters and drinking water resources. The safe level of H2O2 residue has to be controlled through accurate and precise measurement methods. A facile spectrophotometric method for the determination of hydrogen peroxide is based on the reaction of iodine ...

 Background: To determine the efficacy of three different antiseptic solutions (Control group (I), Antibiotic solution – Neomycin and polymyxin (II), Chlorhexidine 0.4% (III), and povidone – iodine 10% (IV)) in disinfecting contaminated bone fragments. Methods: Under sterile conditions, the femora of 12 rabbits were removed and cut into six millimeter pieces. A total of 200 bone specimens were ...

OBJECTIVES The aim of the study was to investigate the clearance of PVP-iodine applied as a gel or solution in periodontal pockets. METHODS Teeth of 12 subjects with at least eight periodontal pockets of ≥5 mm probing depth were isolated with a rubber dam to allow contamination-free access to the pockets. In each subject, three pockets were filled with PVP-iodine gel (10%) and three with PVP-...

Total serum iodine levels were measured for 24 hr in human subjects following a single, oral, therapeutic dose of organically bound iodine administered as iodinated glycerol. In one volunteer, measurements were taken during continued dosing for 6 days and for 48 hr thereafter. Peak levels were attained 1-2 hr after administration of a single dose, with a gradual fall to almost basal levels by 2...

An analytical method for the determination of total iodine at the ng level in urine, biological materials and foods was investigated. The organic substances were completely decomposed using a mixed solution of nitric, perchloric and sulfuric acids as pretreatment agents at ca. 230 degrees C. Iodine in the resulting solution was analyzed by a kinetic-photometric method based on the catalytic eff...

The interaction between povidone-iodine, phagocytic cells, and microorganisms was studied. Three preparations of povidone-iodine were investigated: commercially available povidone-iodine solution Betadine, pure high-molecular-weight povidone-iodine as used in Betadine, and a low-molecular-weight povidone-iodine. Low concentrations of povidone-iodine (approximately 0.005%) have considerable acti...
