ジャーナル フリーHuman, Trigeminal nerve, Motor root, Sensory root, Nerve fiber, Morphometry Summary: We evaluated the components of nerve fibers of the motor and sensory roots of the trigeminal nerve by morphometric analysis. Trigeminal nerves were obtained from 5 cadavers (males, aged 67-95) were stained by Masson-Goldner-Goto method and examined under the microscope using a morphometric image-analyzer. The area and perimeter of axons were larger in the motor root than in the sensory root. The size distribution of axons was wider in the motor root than in the sensory root and the distribution pattern was unimodal type. These findings suggested that nerve fibers of the human trigeminal nerve gave similar findings to those of other peripheral nerves, regarding axonal size distribution and relative size of motor and sensory nerve axons.抄録全体を表示PDF形式でダウンロード (1682K) -

ジャーナル フリーWe studied morphometric nerve fiber analysis and the aging process of the inferior alveolar nerve (IAN). Human IANs were resected at the mandibular foramen. The preparation of sections involved fixation, washing, dehydration, embedding, sectioning and staining as described in our previous reports. We estimated the total number of myelinated axons in the IAN being average 26,200, the transverse area of those being average 37.1 μm2, the average perimeter of those being 23,0 μm, the average circularity ratio those being 0.85, respectively. According to these results, the IAN did not demonstrate notable age-relation change in any measured item. The IAN differed from not only our previous data on the human motor peripheral nerves but also those on the human sensory peripheral nerves. With regard to the aging process, the IAN indicated morphological features compared with other peripheral nerves.抄録全体を表示PDF形式でダウンロード (1465K) -

ジャーナル フリーWe analysed numbers and sizes of the human tibial nerve branch innervating the soleus muscle. The material was taken from 13 cadavers aged from 67 to 98 years. A linear regression analysis disclosed a significant age-related decrease in the mean number per unit area and the mean transverse area of axons. Such decreases with age may indicate atrophy and loss of motoneurons. Our results could help in understanding the correlation between morphology and function during the ageing process.抄録全体を表示PDF形式でダウンロード (1365K) -

ジャーナル フリーThe relationships of both the external branch of superior laryngeal nerve with the superior thyroidal artery and the recurrent laryngeal nerve with the inferior thyroidal artery were examined on the fixed cadavers of 4 adult women and 26 adult men.
A total of 32 external branches of superior laryngeal nerve,16 on each side, were dissected. When left and right sides were assessed alltogether,71.9% were medial to the artery while 28.1% were in between the branches. No nerve was found to be lateral to the artery. Thus the type in which the nerve is exposed to surgical trauma was found to be present in 28.1% of the cases. Only 12 of the cadavers could be assessed for symmetry and three fourths were found to have bilaterally symmetric relationship.
A total of 52 Recurrent Laryngeal Nerves,27 on the left and 25 on the right side were dissected. When bilateral symmetry was assessed in 21 cadavers, one third of the Recurrent Laryngeal Nerves were found to be bilaterally symmetrical. Inferior Thyroidal Artery was missing in 4 sides; bilaterally in one cadaver and unilaterally in 2 cadavers. Thus, artery-nerve relationship was assessed on 48 sides,25 on the left and 23 on the right. On the right,39.2% were in between the branches while 30.4% were anterior to the artery and 30.4% were posterior. On the left,52% were in between the branches whereas 44% were posterior and 4% was anterior to the artery. Thus the position of the nerve in between the branches had the highest incidence while the anterior position had the lowest, the differences being statistically insignificant抄録全体を表示PDF形式でダウンロード (3743K) -

ジャーナル フリーSixty-one human livers obtained from donated Japanese adult cadavers were dissected to reveal the ramification pattern of the portal and hepatic veins, and their topographical relationship in the left anatomical lobe. The segmental portal vein supplying S2 (P2) tended to form a single stem, whereas that of S3 (P3) was usually double. An intermediate branch between P2 and P3 was observed in 23.0% of livers. In spite of variation between livers, definite P2 and P3 were identified in 47 specimens. One tributary of the left hepatic vein (LHV) was usually present for drainage of S2, and two tributaries were present for S3 (sometimes also for S2 and/or S4). The latter two tributaries of the LHV and the two subsegmental branches of S3 showed three patterns of three-dimensional interdigitations. From these results, the portal vein system did not seem to have a two segmental composition (i. e., S2 and S3) in 23.0% of specimens, whereas the hepatic vein system did not have an intersegmental course in 23.4%. Thus, there were obvious limitations in using each system to determine the liver segment. Taking the overlapping cases into consideration, the left anatomical lobe of 41.0% of specimens did not seem to fit the definition of Couinaud's liver segment. In addition, four patterns of fissure vein (or scissural vein), >5 mm in diameter at its terminal, were identified: (1) middle hepatic vein type (left median vein,9.8%); (2) LHV type (left medial vein,41.0%); (3) true fissure vein (3.3%); and (4) absent cases (45.9%). The former two types also suggested limitations of the hepatic vein system as an indicator of the segmental border.抄録全体を表示PDF形式でダウンロード (2408K) -

ジャーナル フリーA 14 year old boy with proximal focal femoral deficiency (PFFD) on left side, contralateral hip dysplasia in association with ulnar hypoplasia and cleft hand was seen our clinic one year ago. From our research, despite it is atypical presentation, this case in a broad context conforms with the femoral-fibula-ulna complex (FFU). This boy was born to healthy and nonconsanguineous parents. Pregnancy and delivery were uncomplicated, and no history of prenatal teratogen exposure, any drug ingestion, infection, diabetes mellitus or other conditions that could be associated with malformation. The patient refused any sort of surgical treatment.抄録全体を表示PDF形式でダウンロード (2948K) -

ジャーナル フリーN-ethyl-N-nitrosourea (ENU) is a potential carcinogenic agent that is commonly used in industry. Therefore the present study aimed to find out the possible effects of this agent on the rat digestive tract especially on the colon. We have studied the complementary mutation activity of the exon 2 of K-ras oncogene by ENU treatment in rat colonal tissue. While the two experimental group rats were injected once a week with 20 mg/kg and 300 mg/kg body weight-body weight with ENU (i. p.), the last experimental group was administered only with PEG and the control group animals received no treatment. Following 45 weeks, all animals were sacrificed and colonal tissues were obtained. Tissues were processed for light and electron microscopy and also for molecular biological analyses. While no colonal tumour development was observed in the control and in the PEG treated group, an extensive tumour development was seen in a wide range of tissues in the high dose ENU treated group. The light and electron microscopical examination of the rat colonal tissue revealed a lymphocyte hyperproliferation in the submucosal region, an increased number of polymorphonuclear leukocytes (PMLs) and occasional epithelial lesions. The mutation analyses of exon 2 of K-ras by HρaII demonstrated more than one recognition sites in the ENU treated group whereas there was only one enzyme cognate site in the control group.抄録全体を表示PDF形式でダウンロード (4504K) -

ジャーナル フリーIn lower vertebrates, the bone-mineralizing hormone "calcitonin" is secreted from ultimobranchial glands, which assume various shapes, e. g., follicles, cellular masses, or cell strands. Histological observations support the view that in some teleosts, the glands increase in size when females maturate. We determined the exact volume of the gland in juveniles and adult males and females of a teleost, Ryukyuayu (Plecoglossus altivelis ryukyuensis). Furthermore, we examined plasma Ca, Na and K levels. In this species, the gland was fundamentally composed of a single follicle. The gland volume was converted to numerical data under a certain condition. It thus became clear that the value of the follicle wall was significantly increased only in maturing and mature females with high plasma Ca levels and that the value of the lumen did not show any statistically significant changes during growth and maturation.抄録全体を表示PDF形式でダウンロード (1885K)
