title: [The diameters of the central canals of the osteons in tubular bones (based on data from scanning electron microscopy and centrifugal porosimetry)].
abstract: The centrifugal poremetry is based on preliminary filling the pores of prepared samples with the working fluid and the following removal of it from the pores at different fixed velocities of rotation. Measurement of the quantity of the remaining fluid after each rotation allows obtaining the distribution of the pore volume depending on their radius. Since the samples are not destroyed they can be used for measuring the pores diameter in electron micrograph. Comparison has been made of the distribution of the pores quantity by their diameters obtained by morphometry with the distribution of the pores volume by their diameters obtained by differentiation of poremetry curves. Besides greater detailization of the prevailing diameters of the pores, the method of poremetry allows the information to be obtained concerning the distribution of not only sizes of central canals of osteons but also smaller pores characterizing the system of lacunae of osteocytes and canals connecting them.
