The novel Sinupret® dry extract exhibits anti-inflammatory effectiveness in vivo.

Sinupret® is frequently used as a herbal medicinal product to treat sinusitis, and it was assumed that anti-inflammatory effects might contribute to its overall beneficial properties. Here, we investigated the effects of a Sinupret® drug mixture (SIN) as well as of the novel Sinupret® dry extract (SIN DE) with the latter containing higher concentrations of active ingredients, in an in vivo model of acute inflammation, the carrageenan-induced pleurisy in rats. Both SIN and SIN DE were administered to rats orally at doses of 100mg/kg (low dose) and 500mg/kg (high dose) 1h prior to intrapleural injection of carrageenan.

Central and peripheral consequences of the chronic blockade of CB1 cannabinoid receptor with rimonabant or taranabant.

The endocannabinoid system plays a crucial role in the pathophysiology of obesity. However, the clinical use of cannabinoid antagonists has been recently stopped because of its central side-effects. The aim of this study was to compare the effects of a chronic treatment with the CB(1) cannabinoid antagonist rimonabant or the CB(1) inverse agonist taranabant in diet-induced obese female rats to clarify the biological consequences of CB(1) blockade at central and peripheral levels.

An animal model of compulsive food-taking behaviour.

The increase in the incidence of obesity and eating disorders has promoted research aimed at understanding the aetiology of abnormal eating behaviours. Apart from metabolic factors, obesity is caused by overeating. Clinical reports have led to the suggestion that some individuals may develop addictive-like behaviours when consuming palatable foods, and compulsive eating plays a similar dominant role in obesity as compulsive drug taking does in drug addiction.
