The optic nerve has been divided into 3 regions: the prelaminar, lamina cribrosa, and retrolaminar regions. However, it currently remains unclear whether the chemoarchitecture of GFAP and GS is homogeneously organized, especially in the retrolaminar region. Strong-to-moderate GFAP immunoreactivity was observed in all 3 regions. The retrolaminar region was further divided into anterior (RLa) and posterior (RLp) retrolaminar regions. More GFAP immunoreactive punctations were observed in the RLa region than in the RLp region. Regarding GS immunoreactivity, moderately GS immunoreactive glial cells were observed in the prelaminar and retrolaminar regions. In the retrolaminar region, there were more of these cells in the RLa region than in the RLp region. GS immunoreactivity was markedly weaker in the prelaminar and retrolaminar regions than in the retina. Thus, the chemoarchitecture of GFAP and GS was heterogeneously organized in the retrolaminar region, and the RLa region was the main GS distribution site in the retrolaminar region. Since GS is a key enzyme of glutamate metabolism, these results may provide clues as to how glutamate is metabolized in the primate optic nerve.

The translocation of NADPH oxidase components to produce antimicrobial free radicals from the vesicles to the phagosomes may be important. Hydrogen peroxide (H2O2) derived from O2- has been observed by electron microscopy using a cerium method. However, 2'-7'-dichlorofluorescin diacetate can also detect H2O2 through fluorescence. The main objective of the present study was to measure the H2O2-dependent fluorescence of PMNs after opsonized zymosan A (OPZ) phagocytosis using a microplate reader under different fixation conditions, including 0.5, 1, and 10% glutaraldehyde (GA) individually for 1, 5, 10, or 30 min. An additional objective was to visualize, through the use of electron microscopic cytochemistry, the process of H2O2 generation in OPZ phagocytic fixed PMNs. The fixed PMNs showed that the largest fluorescent value was produced by a concentration of 0.5% GA for all fixation times. This suggested that the fixation of PMNs with a high concentration of GA inhibited phagocytosis and produced ROS. In the fixed PMNs, electron microscopic results showed that after 1 min of mixing, some PMNs attached to particles and exhibited mild deposits in their secretory vesicles. When PMNs engulfed particles, free radical-producing vesicles had enhanced reaction deposits 10 min later and fused to the phagosomal membrane, releasing numerous free radicals into the lumen. Time-dependent H2O2 production was enhanced in the secretory vesicles, some of which were fused exactly to the phagosome membranes.

Therefore, investigators must select an appropriate mammalian model. Mice and rats are indispensable in the understanding of the mechanisms of human diseases, but other non-rodent mammals are required in certain situations. The rabbit is one such species. The rabbit exhibits greater biological similarities to humans than the mouse or rat, and the rabbit VX2 allograft cancer model has been used in a broad range of oncological studies, such as stromal responses, metastatic behaviors and therapeutic effects. Cancer cells in this model proliferate in a host rabbit that maintains a natural immunity, which makes this model attractive and unique. However, these examples constitute only a small number of advantages of a rabbit model. Numerous reports suggest that the rabbit is an attractive cancer-bearing animal model for the study of cancer metastasis and the lymphatic system. I briefly review the relevant medical literature and compare the rabbit lymphatic system with mice, rats and humans.

The epididymal epithelium consists of principal cells, clear cells, and basal cells. To comprehensively understand the occurrence and morphological differentiation of basal cells, we examined the expression and localization of cytokeratins (CKs) in the epididymal epithelium during postnatal development of the mouse. Immunohistochemical staining showed that, in adult mice, CK5 and CK14 were exclusively expressed in the cytoplasm of basal cells. During postnatal development, basal cells that stained positive for CK5 and CK14 first appeared in immature columnar epithelial cells in mice aged 1 week. The immunoreactivity became progressively stronger in mice aged 2-3 weeks. In mice aged 3 weeks, the immunoreactivity was strong in regions IV and V. In mice aged ≥ 4 weeks, strong immunoreactivity was observed in all epididymal regions. CK5 and CK14 could be useful markers of differentiation in epididymal basal cells. These basal cells originate from immature columnar epithelial cells and are of two types—dome-shaped and flask-shaped—. The flask-shaped cells are mainly located in the initial segment of the mouse epididymis.","PeriodicalId":19462,"journal":{"name":"Okajimas folia anatomica Japonica","volume":"91 4","pages":"83-9"},"PeriodicalIF":0.0,"publicationDate":"2014-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2535/ofaj.91.83","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33330107","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 relationships between the bone mineral densities (BMDs) of lumbar vertebrae and mandibular cortical bone condition in the inferior border using multi-slice computed tomography (CT) were assessed in postmenopausal women. If a strong correlation between them is obtained, the mandibular cortical bone condition may be useful to evaluate the general bone condition. Twenty-two postmenopausal women were enrolled in this investigation. The maximum CT value and width of the mandibular cortical bone (MCW-MSCT) were measured, and the mandibular cortical bone index (MCI-MSCT) was classified using multi-slice CT. BMDs of lumbar vertebrae were measured using dual energy X-ray absorptiometry (DXA), and then the percentage of the young adult mean (YAM) was analyzed. The correlations were investigated between the mandibular cortical bone condition and values of lumbar vertebrae. Weak correlations were observed between MCW-MSCT and the percentage of YAM. Also, significant differences in the percentage of YAM were noted between types of MCI-MSCT. The mandibular cortical bone index (MCI-MSCT) in the inferior border using multi-slice CT may be applicable to evaluate the influence of the general bone condition.
