Resumo
Using a TV unit for microcirculation studies, we studied the density of the entire microvascular network and its arterial compartment in the pia mater of the sensorimotor cortex in intact young and aged rats (2-3 and 22-24 months) and aged rats after a course of vascular peptide bioregulator Slavinorm. The experiments showed that the density of microvascular network in intact animals decreased by 1.6 times with aging. Treatment with the peptide bioregulator 2.5-fold increased the density of the microvascular network in aged rats in comparison with intact animals of the same age, the density of the arterial compartment of the microvascular network in the pia mater increased by 2.8 times.
