Does spasmolytic activity of Rosmarinus officinalis L. involve calcium channels in the guinea pig ileum?
The present results reinforce the use of Rosmarinus officinalis as antispasmodic in folk medicine. Moreover, it is demonstrated the involvement of calcium channels in this activity, but not the participation of nicotinic receptors, prostaglandins or nitric oxide.
The Canadian and expanded GLH ranking systems are no more than aids to establishing priorities. They cannot replace clinical judgement because the importance of individual scoring items is heavily influenced by the ranking of other items. Waiting times for surgery are now grossly excessive despite the use of criteria for entry to the waiting list which are very conservative by international standards. There is no equitable or clinically acceptable way to modify priorities to reduce waiting times, and institution of a booking system is impractical.
