ジャーナル フリーIntercalated duct cells are present in the alpha and beta islets of the moorhen pancreas. The intercalated duct cells adhere to each other via intercellular junctional complexes on the apical side, projecting many microvilli into the lumen. They also extend slender cytoplasmic processes between islet endocrine cells. These intercalated duct cells appear to have a stellate shape, and to wrap their cytoplasm around the endocrine cells. These observations suggest that intercalated ducts not only pass through the islets, but also play a role in support to islet cells.抄録全体を表示PDF形式でダウンロード (1250K) -

ジャーナル フリーFor an accurate assessment of jaw movement, it is critical to understand the comprehensive formation of the masseter. Detailed dissection was performed on fifteen head halves of eight Japanese cadavers in order to obtain precise anatomical information of the course and distribution of the masseteric nerve in the masseter, especially in the zygomaticomandibularis (ZM). Based on detailed innervation investigation, the main trunk of the masseteric nerve ran between ZM and the masseter, and the anterior region of ZM was closely related to the lateral layer of the masseter rather than the medial layer. Considering the positional relationships between the muscles and the innervating branches, it might be proposed that the muscle masses of ZM and the masseter migrate from the posterior side of the temporalis anterolateralward during development. This model is in agreement with the findings in that no nerve branch was observed between the temporalis and ZM.抄録全体を表示PDF形式でダウンロード (2068K) -

ジャーナル フリーThe effect of sinterability manufacturing conditions, such as Si/C ratio, additives, firing temperature on mechanical properties of pressureless sintered SiC having electrical resistivity and oxidation behaviour in moist were studied.
In order to evaluate the possibility of dental implamt application of SiC, the implant study using rat femurs was performed. SiC was implanted in the drilled hole of the femurs and the histologic reaction to SiC was investigated under light microscopy and CMR. SiC provoked endosteal as bone formation. At 1-3 weeks, it was observed the formation of callus around the SiC implant. Finally, the intervening fibrous tissue between the encapsulating bone and SiC was replaced by bone tissue which was outgowing from the encapsulating bone surface. The observed interface between bone and SiC was similar to the bone-HA interface as to morphology. These results indicate the clinical application of SiC as a dental implant.抄録全体を表示PDF形式でダウンロード (2450K) -

ジャーナル フリーNumerical increases in the elements of the vertebral column probably do not occur. In this case,25 presacral vertebrae (PSV) were determined in the vertebral column of a 22-years-old male skeleton. Their distribution was as follows; 7 cervical,12 thoracic,1 thoraco-lumbar,5 lumbar. Sacrum contained 5 vertebrae. In addition, sacralization or lumbarization was not seen.抄録全体を表示PDF形式でダウンロード (971K) -

ジャーナル フリーThe digastric muscles of 99 cadavers were examined bilaterally. In 5 of them, the digastric muscles showed different types of complex abnormalities. These complex anomalies should be kept in mind in functional studies involving the floor of mouth and evaluating the same structures with CT and MR imaging. Secondly, the embryological basis of the isolated anomalies of the anterior digastric muscle with respect to its occurrence together with the mylohyoid muscle stressed in this article needs further studies of their development from the first branchial arch.抄録全体を表示PDF形式でダウンロード (1686K) -

ジャーナル フリーDuring the dissection of the posterior compartment of the left leg, an unusual flexor hallucis longus muscle of a fifty two years-old male cadaver was observed. On the medial side of the flexor hallucis longus, on its lower distal half, a prominent aponeurotic structure was observed. A small unusual muscle mass was attached to this aponeurotic structure. The muscular fibres of the unusual mass were arranged in form of bipennate muscle. It originated via a broad tendon from the muscular fibres of the tibialis posterior and the deep transverse fascia covering the same muscle. It inserted on the aponeurosis of the lower medial half of the flexor hallucis longus muscle. Having in mind the very different pathology in the region of the ankle and the foot, the significance of such a musde mass could be of practical importance.抄録全体を表示PDF形式でダウンロード (654K) -

ジャーナル フリーAn anatomical study was performed in order to obtain help for orientation regarding the cranial base approaches to the anterior cranial base. Cranial base approaches were studied in 8 adult cadaver heads, and morphometric measurements critical in these approaches were achieved in 76 dry skulls. Importance of the surgical anatomy of the opticochiasmatic apparatus, optic canal, sphenoid ridge, and anterior clinoid was emphasised in this study. Observations from the dissections and operative approaches, and measurements between various points were recorded in a specifically designed software, and these data helped both to understand the local anatomy and the relationship to the intimate structures better and to decide the head position, the degree and direction of safe bony removal, and the direction of the operative approach during the surgery. Considerations important in the selection of these structures, anatomical landmarks and distances were discussed.抄録全体を表示PDF形式でダウンロード (1003K) -

ジャーナル フリーThe mitral subvalvular apparatus is so important to attain the integrity of the left ventricular geometric model and sistolic pump function of the heart. We conducted a detailed dissection of the anatomic structure of mitral valve complex and left ventricle of 10 adult hearts from fixed human cadavers (eight male and two female) at Department of Anatomy, Faculty of Medicine of Istanbul University and Department of Cardiovascular Surgery, Kosuyolu Heart and Research Hospital. The distribution of chordae tendinea and classification of musculus papillaris were recorded. The distribution of chordae tendinea varied slightly both anterior and posterior groups. Musculus papillaris was not simetrical in all subjects. Four type of musculus papillaris were distinguished. The insertio angulus of musculus papillaris varied between 20° and 55°. The left ventricular distances (inflow-outflow) and axes (short-long) were determined as the criteria, together with the mitral subvalvular apparatus, to gain the architecture of the left ventricle. We believe that the goal a more precise data collection and developed model will influence our understanding of functional anatomy of left ventricular subvalvular apparatus, and concept of changes in left ventricular configuration after mitral valve surgery.抄録全体を表示PDF形式でダウンロード (1276K) -

ジャーナル フリーOccipital condyle, Foramen magnum, Morphometry, Surgical anatomy, Cranial base surgery Summary: Surgical anatomy that provides the basis for dealing with lesions arising in the lower clivus and ventral foramen magnum was reviewed in 8 adult cadaver heads and 76 dry skulls. The extreme lateral transcondylar approach was performed in cadavers; the morphometric analysis was studied in both the cadavers and the skulls. The landmarks, distances and structures were selected in order to guide the surgical operations in this area. In the paper, surgical approaches to this region are reviewed, and the results are discussed from the standpoint of surgical importance.抄録全体を表示PDF形式でダウンロード (1295K) -

ジャーナル フリーChanges in lectin binding patterns during the development of rat esophageal epithelium were examined by light- and electron-microscopy.
For the light microscopical observations,15 kinds of biotinylated lectins were used. Stainings with these lectins were weak before 17 days p. c. (post coitum). On the other hand, positive reactions were progressively observed after 18 days p. c. Among them, ConA and WGA showed a positive reaction on all layers of the epithelium; whereas DSA was positive for the middle and surface layers and UEA-1 was positive for only the middle layer. Electron microscopical observations revealed that UEA-1 showed a strongly positive reaction along the cell membranes of middle-layer cells, and on the apical cell membranes of basal cells. It also showed positive staining on Golgi membranes of the cells in the middle layer. ConA and DSA showed a positive reaction on cell, Golgi, and nuclear membranes. It was confirmed that the differentiation of the three layers (surface, middle and basal layers) of epithelial cells morphologically started to be observed after 17 days p. c.
These results suggest that the distribution of glycoproteins in the esophageal epithelium changes in accordance with mucous epithelial cell differentiation.抄録全体を表示PDF形式でダウンロード (2059K)
