JOURNAL FREE ACCESSTo examine distribution of sensory neurons of ventral and dorsal cervical cutaneous nerves in dorsal root ganglia (DRGs), DiO and DiI tracers were applied at the proximal section of nerves (transverse superficial cervical and anterior supraclavicular nerves were selected as ventral cervical cutaneous nerves; dorsal cutaneous branches of second, third and fourth cervical nerves were selected as dorsal cervical cutaneous nerves). Located distributions were observed in DRGs of C2, C3, and C4 (25/46 DRGs). Sensory neurons of the ventral cervical cutaneous nerves were distributed in dorso-lateral or dorso-medial portions; neurons of dorsal cervical cutaneous nerves were distributed in ventro-medial or ventro-lateral portions of DRGs. Moreover, sensory neurons of transverse superficial cervical and anterior supraclavicular nerves were mainly distributed from the caudal half of C2 to whole part of C4 DRGs. Results show that there is a tendency for located distribution in two group sensory neurons; also, sensory neurons of ventral cervical cutaneous nerves have a segmental distribution, which has been verified in the brachial and lumbar plexus.View full abstractDownload PDF (3538K) -

JOURNAL FREE ACCESSThe micromorphological characteristics of hepatic sinusoidal endothelial cells and their basal laminae in five different animal species (cow, sheep, guinea pig, pig, and dog) were studied by electron microscopy. Using transmission electron microscopy, a prominent basal lamina was seen only in cow and sheep. In pig and guinea pig, no prominent basal lamina was evident. Basal lamina-like material was occasionally found in dog. Immunohistochemically, basal lamina was found in cow, sheep, and dog. Using scanning electron microscopy, the size of endothelial fenestrae differed between species. These results may suggest that variation of endothelia and their basal laminae of different species is related to differences in nourishment.View full abstractDownload PDF (1545K) -

JOURNAL FREE ACCESSIn the mouse optic nerve, the optic nerve fiber layer in the retina, the optic papilla and the lamina cribrosa sclerae (LCS) just after penetrating the eyeball failed to generate myelin, whereas the optic nerve proper in the orbit was occupied by myelinated nerve fibers. The present study investigated development of the architecture of LCS, where the axons develop from unmyelinated to myelinated type, to elucidate how the initial part of axons was unmyelinated. At the LCS of the adult optic nerve, well developed astrocytes densely formed a cytoplasmic mesh-like frame through which unmyelinated fibers passed. The astrocytes here contained numerous and densely packed intermediate glial filaments and cell organelles. This framework formed by astrocytes appeared to be completed between 7 and 14 postnatal days before oligodendrocyte progenitors, migrated from the chiasm side, reached the proximal end of LCS, and began myelin formation. Thus the failure in myelin formation at the intraocular part and LCS possibly depended upon unsuccessful migration of oligodendrocytes beyond LCS constructed by specialized astrocytes, although other inhibitory factors for myelin formation, such as adhesion molecules distributed around LCS, may be unsolved.View full abstractDownload PDF (7927K) -

JOURNAL FREE ACCESSIn a dissection performed in our department, we observed multiple variations of the greater omentum. The ununusual attachments of the greater omentum were identified. While the right upper part combined with ligamentum teres hepatis, the left upper part had connection with the anterolateral abdominal wall. In addition, the free lower margin of the greater omentum was bound to the front of the abdomen wall. These ununusual attachments contained vessels and nerves. The greater omentum is used in reconstructive surgery of the chest wall. And its ligaments are important in abdominal surgery. Therefore, it is important to keep in mind the different attachments of the greater omentum, so that caution is required during intraabdominal surgery and also in appropriately interpreting the radiographs.View full abstractDownload PDF (933K) -

JOURNAL FREE ACCESSA single coronary artery is a rare congenital anomaly of the coronary arteries where only one coronary artery arises from the aortic trunk by a single coronary ostium, supplying the entire heart. We report a case of a 70 years-old man with mitral valvular insufficiency and atherosclerotic right and left circumflex coronary arteries, in whom coronary angiography showed a single coronary artery arising from a single ostium in the right sinus of Valsalva (R-II-B subtype) and transverse trunk coursed between aorta and pulmonary artery. The clinical significance and subtype of the single coronary artery are discussed.View full abstractDownload PDF (948K)
