The differences between the cells of osteocyte lines derived from bones resulting from membranous and chondral ossification were established in: 1) the magnitude of the mechanical signal, initiating the development of the process of mechanotransduction; 2) the nature of the relationship between the magnitude of the mechanical signal that initiates the reorganization of the architecture of bone structures and the resource of their strength; in membranous bones significantly lower mechanical signal caused a substantially greater increment of bone strength resource; 3) the biological activity of bone structures, bone fragments formed from membranous tissue were more optimal for transplantation; 4) the characteristics of expression of functional markers of bone cells at different stages of their differentiation; 5) the nature of the reaction of bone cells to mechanical stress; 6) the sensitivity of bone cells to one of the factors controlling the process of mechanotransduction (PGI2); 7) the functioning of osteocytes during lactation. These differences reflect the functional requirements to the bones of the skeleton--the supporting function in the bones of the limbs and the shaping and protection in the bones of the cranial vault. These data suggest that the results of research conducted on the bones of the skull, should not be transferred to the entire skeleton as a whole.","PeriodicalId":74226,"journal":{"name":"Morfologiia (Saint Petersburg, Russia)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"34339198","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The children\u0000were divided into 3 groups. The 1st group included\u0000children with decreased tone of the autonomic\u0000nervous system (ANS) and autonomic\u0000hyperreactivity, the 2nd group — children with\u0000increased ANS tone and low autonomic reactivity,\u0000the 3rd group — children with optimal autonomic\u0000tone and normal reactivity. The state of the\u0000nervous structures in the region of adenoid\u0000overgrowths was studied by histochemical\u0000methods, demonstrating adren- and cholinergic\u0000nerve fibers in the same section (incubation in\u0000glyoxylic acid and Karnovsky–Roots method).\u0000Adrenergic nerve fibers with many varicosities\u0000were found mainly in perivasal plexuses, from\u0000which the branches passed subepithelially\u0000between the nodules, and the terminals ofthin\u0000fibers penetrated the lymphoid nodules. The\u0000assessment of the functional activity of adrenergic\u0000nerve fibers demonstrated that in the 1st group the\u0000average luminescence intensity in varicose\u0000extensions and intervaricose areas was equal to\u000022.7±2.5 and 37,2±3.5 conventional units (c.u.),\u0000respectively, in the 2nd group it was equal to\u000057.3±1,4 and 15.5±4.3 c.u., while in the 3rd\u0000group — to 34,3±2,2 and 30.1±3.8 c.u. It was\u0000found that cholinergic nerve fibers were located\u0000similarly to adrenergic fibers, but appeared thicker\u0000and had larger varicosities. The activity of\u0000cholinergic nerve structures could be evaluated by\u0000the staining intensity (from light yellow to dark\u0000brown) and by the number of varicose extensions\u0000in a certain fiber. Similar to adrenergic fibers,\u0000cholinergic nerve fibers often passed from\u0000perivascular plexuses and innervated the lymphoid\u0000tissue.","PeriodicalId":74226,"journal":{"name":"Morfologiia (Saint Petersburg, Russia)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36418170","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Starting from\u0000puberty and thereafter, it was found that CBA/Lac\u0000males as compared with RT mice had lower\u0000testicular mass and epididymal spermatozoa\u0000number. However, spermatozoa functional\u0000capacity of CBA/Lac males was higher as\u0000compared to that of PT mice, since starting with\u0000the puberal period, they were characterized by a\u0000lower frequency of abnormal forms, and in the\u0000post-puberal period — by higher relative\u0000concentrations of motile spermatozoa. Thus, in the\u0000males of laboratory mice studied, the interstrain\u0000differences in the key parameters of\u0000spermatogenesis related to fertility, began to\u0000emerge in the puberal period, and their interstrain\u0000variability may have a compensatory character.","PeriodicalId":74226,"journal":{"name":"Morfologiia (Saint Petersburg, Russia)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"36418176","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SMT was found to be a constant\u0000cardiac structure consisting of the body and two\u0000branches: anterior and posterior.

Narrow and wide forms of SMT\u0000body were considered as its extreme anatomical\u0000variants. It is suggested to distinguish two\u0000anatomical types of SMT: a complete type, in\u0000which SMT was represented by a complex\u0000consisting of body in the form of muscular vallum\u0000and both branches, and an incomplete one, in\u0000which one of the branches was absent.
