Sulfated polysaccharide from Gracilaria caudata reduces hypernociception and inflammatory response during arthritis in rodents.

Polysaccharide from marine alga Gracilaria caudata has potential health benefits, such as anti-inflammatory, gastroprotective and antidiarrheal effects. Here, we investigated the effect of a sulfated polysaccharide from G. caudata (SP-GC) on hypernociception and inflammatory response in arthritis models.

Involvement of Endothelin Receptors in Peripheral Sensory Neuropathy Induced by Oxaliplatin in Mice.

The aim of this study was to evaluate the participation of the endothelin ET and ET receptors and the effects of bosentan in oxaliplatin-induced peripheral sensory neuropathy (OIN) in mice. Adult male Swiss mice received 1 mg/kg of oxaliplatin intravenously, twice a week for 5 weeks. Dorsal root ganglia (DRG) and spinal cords were removed for evaluation of the endothelin ET and ET receptor expression.

Neurotoxic effect of oxaliplatin: Comparison with its oxalate-free analogue cis-[PtII(1R,2R-DACH)(3-acetoxy-1,1-cyclobutanedicarboxylato)] (LLC-1402) in mice.

Studies suggest that oxalate is involved in the development oxaliplatin-induced peripheral sensory neuropathy (OPSN). This study aimed to compare the neurotoxic effects of oxaliplatin with its oxalate-free cytotoxic analogue cis-[Pt(1R,2R-DACH)(3-acetoxy-1,1-cyclobutanedicarboxylato)] (LLC-1402) in mice. Oxaliplatin and LLC-1402 were intravenously injected in male Swiss mice with a total of nine injections.

Antinociceptive and anti-inflammatory effects of Caryocar coriaceum Wittm fruit pulp fixed ethyl acetate extract on zymosan-induced arthritis in rats.

The ethyl acetate extract from the fruit pulp of Caryocar coriaceum Wittm (Caryocaraceae), popularly known as pequi, has wide applications in popular medicine. Preclinical tests have demonstrated the therapeutic properties of the oil. We investigated the antinociceptive and anti-inflammatory effects of Pequi C.
