Context High concentrations of crude protein in ruminant diets may lead to excessive production ruminal ammonia, which stress the animal’s metabolism and impact nitrogen efficiency. This become a problem zero-concentrate feeding systems when pasture grass is rich protein. Polyphenols such as tannins protect part dietary from degradation thus inhibit ammonia formation. Aims The present study scr...

periwinkle (vinca minor l.) is an evergreen perennial herbaceous plant that belongs to the family apocynaceae. the aerial part of this plant contains certain alkaloids such as vincamine, isovincamine and vincine. the most important of these is vincamine that re-duces blood pressure and promotes memory and the ability for mental concentration. mi-cropropagation could be a good alternative for th...

Sanguisorba officinalis L. is known to have anti-inflammatory properties. However, the potential effects of S. officinalis against asthma have not been reported. In the present study, we investigated the protective effects and underlying mechanisms of S. officinalis in a murine ovalbumin (OVA)-induced asthma model. Mice were sensitized and challenged by OVA inhalation to induce airway inflammat...
