ジャーナル フリーThe Maxillary artery is a component of the terminal branch of external carotid artery and distributes the blood flow to upper and lower jawbones and to the deep facial portions. It is thus considered to be a blood vessel which supports both hard and soft tissues in the maxillofacial region.
The maxillary artery is important for bleeding control during operation or superselective intra-arterial chemotherapy for head and neck cancers. The diagnosis and treatment for diseases appearing in the maxillary artery-dominating region are routinely performed based on image findings such as CT, MRI and angiography. However, validations of anatomical knowledge regarding the Maxillary artery to be used as a basis of image diagnosis are not yet adequate. In the present study, therefore, the running pattern of maxillary artery as well as the type of each branching pattern was observed by using 28 sides from 15 Japanese cadavers. In addition, we also took measurements of the distance between the bifurcation and the origin of the maxillary artery and the inner diameter of vessels. These findings thus obtained could contribute to knowledge of improved accuracy of image diagnosis as an index for embolization and for knowledge of an adequate super-selective intra-arterial chemotherapy.抄録全体を表示PDF形式でダウンロード (1522K) -

ジャーナル フリーExtreme replacement of skeletal muscles by adipose tissue was found in an 86-year old Japanese male cadaver during dissection practice for medical students at Oita University School of Medicine. Especially, the bilateral sartorius muscles looked overall like adipose tissue. The man had suffered from diabetes mellitus, renal failure, hypertension and hypothyroidism before his death. He was also an alcohol drinker. He had been bedridden late in life. The cause of death was renal failure. In microscopy, the adipose tissue-like sartorius muscle was shown to consist of leptin-positive adipocytes with a small number of degenerated muscle fibers. Fatty replacement, or fatty degeneration, appears to result from endocrine and metabolic disorders, and being bedridden leads to muscle atrophy and damage, although the origin of the adipocytes which emerged in the degenerated muscles is unknown.抄録全体を表示PDF形式でダウンロード (3730K) -

ジャーナル フリーFor the purpose of studying the relative position of the mylohyoid line, 156 Japanese mandibles (62 dentulous, 94 edentulous) were measured and comparisons made between specimens. Resorption of bone above the level of the mylohyoid line was recognized but no obvious changes were noted below the level of the mylohyoid line, except in rare cases. A straight pattern of the mylohyoid line was observed most frequently, with the segment of the mylohyoid line between the first and second molars being straight. The mean ratio between the total height of the mandible and the height of the mylohyoid line at the level of mesiolingual cusp of the lower first molar was 1:0.65 in males and 1:0.66 in females. These results will be useful in the fabrication of dental prostheses because the level of the occlusal plane can be estimated for edentulous patients using the proportional data for the the mylohyoid line’s position.抄録全体を表示PDF形式でダウンロード (958K) -

ジャーナル フリーThis study was designed to examine whether lymphatic vessels are present in the lobules of major salivary glands in the rat. Immunostaining with an antibody against podoplanin, a lymphatic endothelial cell marker, was performed on sections of the submandibular, sublingual and parotid glands. Light microscopy demonstrated podoplaninpositive lymphatic vessels around the interlobular ducts and the interlobular arteries and veins in the interlobular connective tissue in all of the major salivary glands. No podoplanin-positive lymphatic vessels were found in the lobules. Electron microscopy also demonstrated lymphatic endothelial cells showing podoplanin expression only in the interlobular connective tissue. These findings suggest that the lymphatic system of the rat major salivary glands originates in the interlobular connective tissue, and not in the lobules.抄録全体を表示PDF形式でダウンロード (2552K) -

ジャーナル フリーOn the basis of light and electron microscopic observations of the post natal development of the hamster submandibular gland, granules in the acinar cells showed considerably variations in size and shape, as well as electron density of the peroxidase-positive reaction. The present study shows that secretory granules of the hamster submandibular gland undergo changes of area and of intensity for peroxidase activity 6 months after birth.抄録全体を表示PDF形式でダウンロード (4586K) -

ジャーナル フリーTo better assess the efficacy of mechanical preparation of root canals, transparent specimens of 250 extracted maxillary canines were investigated for canal configuration, thickness and curvature of the root canal, condition of any accessory canals, and location of the apical foramen. Fewer than 40% of the specimens showed accessory canals that were mechanically impossible to clean. The majority of the lateral branches were small, greater than a #15 file, and none of the branches were larger than a #20 file. Although apical foramina located away from the apex were observed in 30% of the maxillary teeth, 96% of all apical foramina were within 0.5 mm of the apex. Data on the thickness of the root and main canal in the apical portion and curvature of the root canal suggest that, for adequate apical preparation, a #60 file must be able to reach the apical constriction.抄録全体を表示PDF形式でダウンロード (1386K)
