生物活性

Polyvinylpyrrolidone is a compound which has been widely tested and used in human and veterinary medicine as an effective wound healing accelerator and disinfectant when combined with iodine and other compounds.

体内研究
(In Vivo)

Goldfishes which are treated with salt have significantly lower mucus weights at 25 h. Goldfishes treated with Polyvinylpyrrolidone (PVP) have significantly higher mucus weights at 25 h. Koi treated with salt and Polyvinylpyrrolidone (PVP) has significantly lower mucus weight at 1 and 25 h. Control koi has significantly higher mucus at 25 h. At the end of 2 weeks, it is determined that the three koi treated with salt and Polyvinylpyrrolidone(PVP) remain healthy and show a higher degree of healing than other treatment koi and the control group[1].

Animal Administration
[1]

Each fish within a tank serves as a replicate. Treatments are designated as Polyvinylpyrrolidone (at a dose of 10 mL/10 gallon) and saline/salt at 3g/L. A control group that does not receive any chemical is also included in the study. All fishes from each treatment group are sampled at 0 min, 15 min, 1 h, 4 h and 25 h. At each time interval, all fishes from each treatment group are anaesthetized using buffered tricaine methanesulfonate, weighed, and slime is scraped from one 1 cm2 area over the epaxial musculature using a preweighed plastic coverslip[1].
