In this work the analysis\u0000was performed of the linear dimensions of the liver,\u0000its right and the left lobes measured during spiral\u0000computed tomography (SCT), taking into account\u0000the anatomic variability of the position of the organ,\u0000in 193 individuals of both sexes of juvenile and first\u0000period of mature age without pathology of the liver\u0000and cardiovascular system. Besides the\u0000traditionally distinguished variants of the position of\u0000the organ in the abdominal cavity, in part of the\u0000individuals examined the combined displacement\u0000of the organ relative to the sagittal and frontal\u0000planes was noted. It was demonstrated that in\u0000combined displacement of the liver in two planes,\u0000linear parameters of this organ were extremely\u0000changeable and approached the extreme variants\u0000of the anatomic variability. The dependence of\u0000traditionally measured linear parameters of the\u0000liver from the anatomic variant of organ position in\u0000the abdominal cavity was studied. The data\u0000obtained suggest that the interpretation of SCT\u0000results without consideration of the anatomic\u0000variant of organ position may lead to erroneous\u0000judgments about the size of the liver and its\u0000individual parts.","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":"36423004","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 experiments were conducted on 40 outbred albino male mice weighing 20-25 g, which were injected intraperitoneally with HPM at the dose of 100 μg/kg of body weight per day for 5 days. Relative volumes occupied by the epithelium (E), including its follicular (E(f)), interfollicular (E(i)) components, and colloid (C) were determined using stereological method on TG transverse sections. E(f)/E(i) and E/C ratios were calculated as the indices of follicular organization and TG activity, respectively. Mitotic activity of thyrocytes was also evaluated. The enzymes, characterizing the metabolic activity of thyrocytes: NADH-diaphorase, succinate- and lactate dehydrogenases were demonstrated on cryostat sections of material, frozen in liquid nitrogen and their activity was assessed cytophotometrically. The results demonstrated that HPM administration lead to a significant increase in relative volume of thyroid epithelium with a concomitant reduction of the volume of the colloid. E(f)/E(i) ratio was not significantly different from that in the control. HPM also induced a significant increase of thyrocyte proliferation rate and of the activity of enzymes studied. Collectively, the quantitative histoenzymological and morphometric data obtained indicate the stimulating effect of HPM on TG functional activity and thyrocyte proliferation.","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":"34729639","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}

Histological sections were stained with hematoxylin-eosin and Shubich's method (to demonstrate mast cells). The expression of Ki-67, CD3 and CD34 was assessed by immunohistochemistry. The ultrastructure of thymic tissues was also examined. It was found that the severity of hypoxia determined the morphological changes in the organ associated with a development of large complex of tissue reactions. A disruption of internal structure and a loss of integrity of epithelio-reticular cells and thymocytes were demonstrated in ultrathin sections. Thymocyte proliferation index (Ki-67) and thymocytopoiesis intensity (CD3+) were reduced in all the zones of the thymus. The degree of hypoxia affected the redistribution of CD3+ lymphocytes leading to their accumulation in the medulla. The processes of endogenous regeneration took place which involved the cells of fibroblastic line and progenitor cells (CD34+) together with active formation of new blood vessels. These findings suggest that the morphological changes identified in the tissues of the thymus are a manifestation of tissue adaptation to hypoxia of varying severity under conditions of endogenous regeneration, simultaneously reflecting the processes of substitution cytogenesis.","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":"34729638","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}

MI efferent fibers (4y, 6ab areas) preferentially projected to ventral posterolateral and medial (VPL, VPM), ventrolateral (VL), and reticular (R) nuclei, localized in rostral part of the thalamus (T), as opposed to SI (areas 1, 2, 3a, 3b), which projected preferentially to caudal part of T, VPL, VPM and R nuclei. Latero-medial organization of cortico-thalamic connections was demonstrated, with predominant localization of cortical representation of hindlimbs in the lateral part of VPL, of forelimbs--in the medial part of VPL, of face and head--also in VM and VPM. Quantitative analysis of the distribution of corticothalamic efferents of different somatotopical representations of MI has demonstrated the most extensive, massive connections with T nuclei (VPL, VL, R) of the motor representation of forelimb, followed by the representation of hindlimb, trunk and, finally, the minimal projection of the representation of face and head. As opposed to motor representation of the forelimb and also of the face and head, with uniform distribution of fibers in VPL, VL and R, the number of efferents of motor representation of hindlimb, passing in VL, was almost 2.5 time lower than in VPL and R, whereas the representation of trunk had the predominant projection to VL. Dominant cortico-thalamic connection suggests greater involvement of T nuclei studied in the realization of functional specialization of certain somatotopical representations of MI.","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":"34728321","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}
