    Peculiarities of extra-intraorgan innervation of uretral pacemaker zones (upper and lower urethral narrowings) were investigated. Anatomic-histological investigation results showed that upper (the I order pacemaker) and middle (the II order pacemaker) pacemaker zones of the ureter are innervated by single nerve stems from lower aortic-renal ganglion of plexus nervosus. Presence of microganglia in their intramuscular plexus nervosus is the peculiarity of intraorgan innervations of uretral pacemaker zones. The data obtained contribute to cystoid-peristaltic theory of uretral motility organization.Π˜Π·ΡƒΡ‡Π΅Π½Ρ‹ особСнности экстра- ΠΈ ΠΈΠ½Ρ‚Ρ€Π°ΠΎΡ€Π³Π°Π½Π½ΠΎΠΉ ΠΈΠ½Π½Π΅Ρ€Π²Π°Ρ†ΠΈΠΈ пСйсмСйкСрных Π·ΠΎΠ½ ΠΌΠΎΡ‡Π΅Ρ‚ΠΎΡ‡Π½ΠΈΠΊΠ° (Π²Π΅Ρ€Ρ…Π½Π΅Π΅ ΠΈ срСднСС ΠΌΠΎΡ‡Π΅Ρ‚ΠΎΡ‡Π½ΠΈΠΊΠΎΠ²Ρ‹Π΅ суТСния).

    Reaction of the skin vessels and tissues after microsurgical replantation of the free axial groin flap (FAGF) under the influence of eplir was investigated. Studying of skins vascular bed on microanatomical preparations was spent by means of a technique of an intravascular injection of Gerots mass and histological preparations. After transplantation FAGF signs of developments of stagnation, augmentation of numerical density of vessels are observed; restoration of vascular communications begins about 14 days. After application of various forms of eplir germination of vessels in surrounding tissues is observed with 7 days, morphological changes of a vascular bed are less expressed. Application of various forms of an extract a silt sulphidic muds essentially improves processes of adaptation and integration of free axial flaps.Π’ экспСримСнтС Π½Π° крысах исслСдовали Ρ€Π°Π½Π½ΠΈΠ΅ сосудистыС ΠΈ Ρ‚ΠΊΠ°Π½Π΅Π²Ρ‹Π΅ Ρ€Π΅Π°ΠΊΡ†ΠΈΠΈ свободного ΠΏΠ°Ρ…ΠΎΠ²ΠΎΠ³ΠΎ лоскута послС Π΅Π³ΠΎ Ρ€Π΅ΠΏΠ»Π°Π½Ρ‚Π°Ρ†ΠΈΠΈ ΠΈ постопСрационного использования Π°ΠΏΠΏΠ»ΠΈΠΊΠ°Ρ†ΠΈΠΉ эплира Π² Ρ€Π°Π·Π»ΠΈΡ‡Π½Ρ‹Ρ… Ρ„ΠΎΡ€ΠΌΠ°Ρ… выпуска (гСль, 1%-ΠΉ масляный раствор).

    Metabolic Turnover of Synaptic Proteins: Kinetics, Interdependencies and Implications for Synaptic Maintenance

    Chemical synapses contain multitudes of proteins, which in common with all proteins, have finite lifetimes and therefore need to be continuously replaced. Given the huge numbers of synaptic connections typical neurons form, the demand to maintain the protein contents of these connections might be expected to place considerable metabolic demands on each neuron. Moreover, synaptic proteostasis might differ according to distance from global protein synthesis sites, the availability of distributed protein synthesis facilities, trafficking rates and synaptic protein dynamics. To date, the turnover kinetics of synaptic proteins have not been studied or analyzed systematically, and thus metabolic demands or the aforementioned relationships remain largely unknown. In the current study we used dynamic Stable Isotope Labeling with Amino acids in Cell culture (SILAC), mass spectrometry (MS), Fluorescent Non-Canonical Amino acid Tagging (FUNCAT), quantitative immunohistochemistry and bioinformatics to systematically measure the metabolic half-lives of hundreds of synaptic proteins, examine how these depend on their pre/postsynaptic affiliation or their association with particular molecular complexes, and assess the metabolic load of synaptic proteostasis. We found that nearly all synaptic proteins identified here exhibited half-lifetimes in the range of 2-5 days. Unexpectedly, metabolic turnover rates were not significantly different for presynaptic and postsynaptic proteins, or for proteins for which mRNAs are consistently found in dendrites. Some functionally or structurally related proteins exhibited very similar turnover rates, indicating that their biogenesis and degradation might be coupled, a possibility further supported by bioinformatics-based analyses. The relatively low turnover rates measured here (∼0.7% of synaptic protein content per hour) are in good agreement with imaging-based studies of synaptic protein trafficking, yet indicate that the metabolic load synaptic protein turnover places on individual neurons is very substantial
