Dietary intervention with avocado (Persea americana Mill.) ameliorates intestinal inflammation induced by TNBS in rats.

Nutritional interventions have been shown to be an interesting approach for the treatment of chronic diseases, including inflammatory bowel disease (IBD). Persea americana Mill. (avocado), is a potential food to be used for the prevention or treatment of intestinal inflammation, due to its nutritional value and pharmacological effects.

Bidens pilosa (Black Jack) Standardized Extract Ameliorates Acute TNBS-induced Intestinal Inflammation in Rats.

is an herb popularly used to treat inflammation, hemorrhoids, fever, and gastric ulcers with reported pharmacological activities and chemical composition that sustain its selection as a potential intestinal anti-inflammatory product. Based on this, we examined the effects of a fatty acid-standardized supercritical preparation on the intestinal inflammatory process induced by trinitrobenzenesulphonic acid in rats, using either preventative or curative treatments. We also investigated the safety of plant extract by acute and sub-chronic toxicological analysis.

Nectar Replaced by Volatile Secretion: A Potential New Role for Nectarless Flowers in a Bee-Pollinated Plant Species.

The presence of nectarless flowers in nectariferous plants is a widespread phenomenon in angiosperms. However, the frequency and distribution of nectarless flowers in natural populations, and the transition from nectariferous to nectarless flowers are poorly known. Variation in nectar production may affect mutualism stability, since energetic resource availability influences pollinators' foraging behavior.

Chemical Composition and Bioactivity of Essential Oil from Blepharocalyx salicifolius.

Natural products represent a source of biologically active molecules that have an important role in drug discovery. The aromatic plant has a diverse chemical constitution but the biological activities of its essential oils have not been thoroughly investigated. The aims of this paper were to evaluate in vitro cytotoxic, antifungal and antibacterial activities of an essential oil from leaves of and to identify its main chemical constituents.

Intestinal anti-inflammatory activity of Ground Cherry ( L.) standardized CO phytopharmaceutical preparation.

Aim: To investigate the effects of Ground Cherry ( L.) standardized supercritical CO extract in trinitrobenzenesulphonic acid (TNBS) model of rat intestinal inflammation.

Methods: The animals were divided into groups that received vehicle or extract (PACO) orally at the doses 25, 50 and 100 mg/kg daily by 5 d before TNBS damage.
