Chlorhexidine (CHX) is an over-the-counter antiseptic amply used by the population. There are reports that CHX acts in mitochondria as an uncoupler and inhibitor. The purpose of this study was to investigate the short-term effects of CHX on hepatic metabolic pathways linked to energy metabolism in the perfused rat liver.

The alkaloid boldine occurs in the Chilean boldo tree (). It acts as a free radical scavenger and controls glycemia in diabetic rats. Various mechanisms have been proposed for this effect, including inhibited glucose absorption, stimulated insulin secretion, and increased expression of genes involved in glycemic control.

Aims: to investigate the effects of resveratrol on glycogen catabolism and gluconeogenesis in perfused livers of healthy and arthritic rats. The actions of resveratrol-3-O-glucuronide (R3G) and the biotransformation of resveratrol into R3G was further evaluated in the livers.

Main Methods: arthritis was induced with Freund's adjuvant.

Background And Aim: The present study investigated the effects of orally administered α-tocopherol-loaded polycaprolactone nanoparticles on the articular inflammation and systemic oxidative status of middle-aged rats with Freund's adjuvant-induced polyarthritis, a model for rheumatoid arthritis. Intraperitoneally administered free α-tocopherol provided the reference for comparison.

Experimental Procedure: Two protocols of treatment were followed: intraperitoneal administration of free α-tocopherol (100 mg/kg i.
