ジャーナル フリーThe developmental histology of the temporomandibular joint (TMJ) was investigated in 10 fetuses of 4 to 10months of gestational age. The S-type structure of the disc is formed by the following bases: 1) the flat upper and concave lower surfaces of the disc; 2) thinner intermediate zone and thicker anterior and posterior bands; 3) the projection of the articular tuberculum and superoposterior growth of the condyle. The posterolateral part of the disc was the thickest and the corresponding part of the fossa was the deepest. The condyle was originally positioned beneath the part of disc that was considered the main force-bearing area. The distribution and arrangement of elastic and collagen fibers in the disc was proportional to disc function. Gross elastic fibers in the posterolateral part of the posterior band were connected with the upper head of the pterygoideus lateralis muscle fibers running medioanteriorly. They were indicated to be antagonistic with each other. At 4 months of gestational age, a few elastic fibers appeared in the bilaminar region and began to form bundles as the fetus grew. At full-term dense elastic fibers were found in the upper stratum of the bilaminar region.抄録全体を表示PDF形式でダウンロード (2700K) -

ジャーナル フリーAn antiserum against basic fibroblast growth factor (bFGF) was characterized by immunoblot and used to localize bFGF-immunoreactivity in the adult rat retina. Crude homogenate of the retina, when examined with immunoblotting, exhibited a main band with the same molecular weight (18kDa) as bFGF. Light microscopic immunohistochemistry demonstrated intense bFGF staining in the photoreceptor outer segments and the outer plexiform layer, and weak immunoin some cells of the outer nuclear layer, inner nuclear layer and ganglion cell layer. The most intense bFGFimmunoreactivity was noted in glial (Müller) cells with vertically oriented thin processes. There were also immunoreactive pigment epithelial cells and mesenchymal cells in the choroid. Under electron microscopy, the outer plexiform layer was found to contain immunoreactive products exclusively in the axon terminals of photoreceptor cells which formed synapses with bipolar cell processes. The more widespread and uneven localization of bFGF-immunoreactivity in the mature rat retina than previously demonstrated suggests that endogenous bFGF is involved in complex physiological events other than retinal regeneration and histogenesis.抄録全体を表示PDF形式でダウンロード (3768K) -

ジャーナル フリーLectin-gold-silver (LT-G-S) procedures using two lectins (RCA-I and Con A) were applied to appropriately prepared paraffin sections of tongues in the rat and guinea pig. In the lingual mucous membranes of the rat and guinea pig, positive RCA-I-G-S and Con A-G-S reactions were obtained in the intercellular spaces and the cytoplasm of epithelial cells of the basal and intermediate layers respectively. Likewise, the LT (RCA-I and Con A)-G-S techniques gave rise to varying intensities of positive reactions in the serous and mucous gland acini, nerve and muscle fiber bundles and connective tissue elements. The results obtained in the present study indicate that in the rat and guinea pig tongues the histologic structures mentioned contain varying amounts of β-D-galactose and α-D-mannose or α-D-glucose residues of glycoconjugates, and that such histochemical properties of some of the lingual structures can be correlated with their possible histophysiological functions.抄録全体を表示PDF形式でダウンロード (5405K) -

ジャーナル フリーA discoid-shaped ectopic kidney located in front of the right common iliac artery was observed in a 71-year-old Japanese man. The right kidney was normally positioned, but the left kidney was not observed in the normal position. The ureter of the ectopic kidney descended laterally to the left ductus deferens. The ectopic kidney received three arteries which arose from the anterior aspect of the abdominal aorta. Two of the arteries supplied the left half of the kidney. The other supplied the right half and gave off two branches to the adipose tissue around the right kidney; these branches meant that this artery belonged to the right side. Venous drainage from the kidney was handled by two veins. One collected venous radicles from the right half of the kidney and flowed into the inferior vena cava; this vein belonged to the right side. The other served the left half and joined with the left lumbar vein, which finally drained into the left common iliac vein; this vein was attributed to the left side. The present ectopic kidney had a left-side ureter, and vascular supply on both the right and left sides. This disunity or dissociation of laterality in the vessels and the ureter seemed to be strongly related to the location of this ectopic kidney in the median region.抄録全体を表示PDF形式でダウンロード (2424K) -

ジャーナル フリーThe importance of the hymenal configuration lies in the fact that it is accepted as an important sign of the virginity in many countries and also it needs a clearcut definition for the forensic evaluation of child abuse and rape. To improve understanding of configuration of the normal hymen we studied 100 prepubertal hymens. In addition to the most commonly seen types we found the fimbriated hymen at a high rate especially in adolescents. There was another configuration the appearance of which differed on each half of the vaginal orifice; one half had a labium while the other had fimbriae. The tagged type hymen was also encountered.抄録全体を表示PDF形式でダウンロード (2350K)
