[Relative volume of functioning capillaries in the skeletal muscle in regional hypotension]

Experiments on rats demonstrated that one month after the reduction of pressure in the vessels of the hind part of the body caused by narrowing of the abdominal aorta lumen the number of functioning capillaries in the gastrocnemius and the soleus muscles was practically the same as in control animals. These results allowed the authors to assume that a decrease of the hydraulic resistance of the resistive vessels in the area of chronic local arterial hypotension was not connected with an increase in the number of parallelly functioning vessels.
