In canine cutaneous veins cooling augments and warming depresses the responses to sympathetic nerve stimulation. In these veins the extract of Ruscus aculeatus (Ruscus) causes contractions due to alpha-adrenergic activation. To determine the effects of temperature on the response to Ruscus, rings of

We investigated the influence of alpha-adrenoceptors blockers and calcium blockers on the effects of the venotonic agent Ruscus extract on the diameter of arterioles (ID 10-70 microns) and venules (ID 20-135 microns) of hamster cheek pouch microvasculature in vivo. For microcirculatory measurements,

Extract of Ruscus aculeatus is used in treatment of venous insufficiency. In the present study, we used the hamster cheek pouch preparation and investigated in vivo the effects of an alpha 1 and alpha 2 adrenoceptor antagonists, a calcium blocker, Ruscus extract, and their combination on increased
