[The muscular blood flow in rats in ontogenesis as measured by the needle probe laser Doppler flowmeter "LAKK-01"].

In anesthetized Wistar rats of the age of 4, 13, 30 and 90 days, blood flow in m. gracilis was measured with the aid of laser-Doppler flowmeter "LAKK-01" with a needle probe. The sharpest postnatal falling of a muscular blood flow was revealed in the first month of life. Features of measurement of the blood flow and biological background by a needle probe in skeletal muscles of rats of various age described.
