In chicken Leghorn, blood flow volume speed in pectoralis and gastrocnemius muscles was measured on 15 and 19 day-old embryos and at the 1st and the 10th days alter hatching. It was revealed that in the last quarter of embryogenesis BF in muscles did not vary remaining in both muscles in identical limits. Similar BF parameters in pectoralis and(More)
In chicken Leghorn, blood flow volume speed (BF, laser-Doppler flowmetry) in the brain hemispheres and in liver was measured on days 10, 14, and 19 of embryogenesis and on day 4 after hatching (in experiments on late embryos and chickens, urethane narcosis was used). It was revealed, that initial BF in investigated organs was 2-fold lower than earlier(More)
The oxygen diffusion coefficients in isolated skeletal muscle fibres of Baikal seal and grayling, white rat, chicken were calculated on the basis of experimentally determined curve of dependence of the O2 consumption on pO2 and the radius of the fibres. In all the cases, the diffusion coefficient was smaller in the fibres than in water. The oxygen diffusion(More)
Using light and electron microscopy, more rapid morphological development of m. gastrocnemius as compared to m. pectoralis was demonstrated in chicken by the 10th day. In m. pectoralis some immature fibers with centrally located nuclei are found, its muscle fibers are generally thinner, contain smaller mitochondria which occupy lesser relative volume, and(More)
In the 4-, 13-, 30-, and 65–90-day old anestetized Wistar rats (8–15 rats in each group) the voluminous blood flow rate was measured in liver, kidney, small intestine wall, and in the predominantly white gracilis muscle of femur. A LAKK-01 laser-Doppler flowmeter and its cutaneous (for kidney) and needle (for other organs) probes were used; they provided(More)
The diameter, length, and numerical density of capillaries, diameter of muscle fibers, size and numerical density of mitochondrial profiles, and relative volume of mitochondria in them were determined in the chicken red oxidative gastrocnemius and white glycolytic pectoral muscle during development from day 10 of embryogenesis to six month of postnatal(More)
Intravital microscopy revealed that 65% of all the m. cremaster's capillary bed were perfused at rest. The capillary functional reserve may play an important part in the topographical heterogeneity of the perfusion. The heterogeneity is a passive mechanism in an increasing number of perfused capillaries, i.e. the "capillary recruitment".
A restructuring of the capillary bed—from the embryonic structure with a three-dimensional network of wide and long protocapillaries to the mature structure with high density of thin and short capillaries along the fibers—has been demonstrated in the chick skeletal muscle on embryonic days 10–19 by morphometric analysis. In this case, the specific blood(More)
