Sodium diatrizoate (Diatrizoic acid sodium salt)

Animal experiment:

Female Sprague-Dawley rats (200 to 250 grams) are housed in temperature and humidity controlled rooms with free access to food and water and maintained on a 12 h light/dark cycle. Rats are anesthetized by a 67.5 mg/kg ketamine, 3.5 mg/kg xylazine and 0.66 mg/kg acepromazine subcutaneous cocktail. While under anesthesia, rats are placed on a heating pad to maintain a body temperature of 37°C. Sodium diatrizoate nanoparticle agglomerates (10 mg) is administered by intratracheal insufflation using a dry powder insufflator. At the end of the experiment, the rats are euthanized by isoflurane inhalation overdose followed by harvest of major organs[1].
