In Vitro |
MIC values of Povidone iodine (PVP-I) are 31.25 mg/L and 7.82 mg/L, respectively. Treatment of the cells with Povidone iodine (PVP-I) at a dilution of 1:32 causes a sharp reduction in cell viability by 90-95% on all testing cell lines[1]. |
|
In Vivo |
The Dp+Povidone iodine (PVP-I) group has the second highest average score from day 13 to the end of the experimental period. The Dp+Povidone iodine and Dp+Et-OH groups also show a significantly increase in eosinophil count compare with the control group (p<0.05 and p<0.001, respectively). However, the eosinophil count does not significantly differ among the Dp+Povidone iodine (PVP-I), Dp+CHG, and Dp+vehicle groups[2]. |
|
Cell Assay |
Each bacterial isolate is washed twice with phosphate-buffered saline (PBS, pH 7.2), centrifuged for 10 min at 1932xg at 20°C, and suspended in 3 mL of nutrient broth, adjusted to a turbidity equivalent of 0.5 McFarland standard. The bacterial suspension is diluted 1:100 with MHB to a final inoculum of 106 colony-forming units (cfu)/mL. For each bacterial strain, two rows of a 96-well microtitre plate are filled with the final bacterial inoculum (50 μL per well) and 50 μL of each serial dilution of ILαD. The procedure is repeated for the Povidone iodine (PVP-I) serial dilutions[1]. |

Animal Admin |
The mice are divided into 6 groups as follows: 1) saline+vehicle (control group), 2) Dp+vehicle, 3) Dp+BZK, 4) Dp+Povidone iodine (PVP-I), 5) Dp+Et-OH, and 6) Dp+CHG. Animals in the experimental groups are exposed to the allergen through the subcutaneous injection of 5 µg of Dp dissolving in 10 µL of saline in the ventral side of the right ear 2 to 3 days a week (a total of 8 times) under anesthesia with 4% halothane. Animals in the control group are not sensitized, receiving a subcutaneous injection of 10 µL of saline in the ventral side of the right ear. Animals receive an application of antiseptic agent are exposed to the allergen and treated with 0.2% (w/v) benzalkonium chloride (Dp+BZK), 10% (w/v) povidone-iodine (Dp+PVP-I), 80% (v/v) ethanol (Dp+Et-OH) or 0.5% (v/v) chlorhexidine gluconate (Dp+CHG). These agents are applied a total of 15 times during the experimental period. The BZK, Povidone iodine (PVP-I), Et-OH, and CHG are dissolved in 25 µL of injection water and applied gently to the dorsal side of the right ear using a micropipette with a fine plastic tip. The animals in the Dp+vehicle and control groups receive 25 µL of injection water. All animals are sacrificed on the last day of the experiment (day 18)[2]. |

25655-41-8 Description |
|
Povidone iodine is iodophor, used as topical antiseptic in surgery and for skin and mucous membrane infections, also as aerosol. A 10% povidone iodine solution contains 1% available iodine, but free-iodine is at 0.1% concentration. Skin exposure causes irritant rather than allergic contact dermatitis. In such a situation, however, iodine seems to be the true hapten. |

25655-41-8 Uses |
|
Povidone iodine has bactericidal effect like iodine. It can be used as disinfectant and bacteriostatic agent in the medicine for anti-septic purposes for eye drops, nasal drops, and cream agents. It can also be made into disinfectant. povidone iodine is mainly used for the skin disinfection and equipment disinfection in hospital surgery and injections as well as prevention of infection in the field of stomatology, gynecology, surgery, and dermatology; it can also be used for disinfection of household utensils and appliances; for food industry and aquaculture industry, it is used for disinfection and animal disease control. It is the preferred international and domestic choice of medical iodine-contained fungicides and disinfectants for epidemic prevention. povidone iodine is a kind of iodine carrier, the so-called “tamed iodine”. Because this product can gradually release iodine to exert an antibacterial effect; its mechanism of action is through causing the protein denaturation and further death of bacteria. It is effective in treating bacteria, fungi, as well as viruses with a relative small tissue irritation effect. |

25655-41-8 Preparation |
|
Povidone Iodine Solution is an antiseptic and disinfectant agent. The preparation method of povidone iodine: be that 1.17% potassium iodide is dissolved in part water in 10% water by mass percent, 2.34% iodine is added to wherein stirring and dissolving, be mixed with iodine solution standby; 0.01% stability auxiliary agent is dissolved in part water 10% water standby; In complex reaction still, add remaining water, open and stir, dropping into 10.0% polyvinylpyrrolidone k30 dissolves, then substep adds above-mentioned two kinds of solution that prepare, finally add 7.5% solvent normal propyl alcohol, after feeding intake, allow reactant mixture at 20 ℃, react 2 hours, react complete mixture is lowered the temperature and obtained betagen solution. |

25655-41-8 Biological Activity |
|
Povidone iodine is a microcide with broad-spectrum activity against bacteria, fungi, viruses, and protozoans. It reduces total anaerobic and aerobic bacterial counts in vitro in dog feces when applied topically as a 10% solution. Povidone iodine decreases bacterial counts and the occurrence of anastomotic leaks in a dog model of emergent resection and anastomosis of the sigmoid colon when applied in situ at a concentration of 10% v/v. Topical administration of povidone iodine (10% v/v) also reduces bacterial counts on the skin of cynomolgus monkeys. Formulations containing povidone iodine have been used to disinfect skin before and after surgery. |
