Tissue bioavailability of anthocyanins from whole tart cherry in healthy rats.

Our aim was to confirm and identify the presence of tart cherry anthocyanins in several target tissues of healthy rats. Liquid chromatography-mass spectrometry analysis was employed for detection and characterisation of anthocyanin metabolites. It was shown that four native anthocyanins, namely cyanidin 3-glucosylrutinoside, cyanidin 3-rutinoside, cyanidin 3-rutinoside 5-β-D-glucoside, and peonidin 3-rutinoside were differentially distributed among targeted tissues of rats.

Flushing induction chambers used for rodent anesthesia to reduce waste anesthetic gas.

Anesthetic induction chambers used for medical research are a substantial source of waste anesthetic gas (WAG). Ideally, any generated waste gas should be actively vented away from personnel operating the chamber by either a ventilated hood or snorkel. Unfortunately, the ideal environment for anesthetizing rodents is not always available.
