ジャーナル フリーSummary: The lower motor center of the rat extraocular muscles was studied using the fluorescent double labeling techique. Double labeled neurons were observed in the oculomotor nucleus between the inferior rectus and levator palpebrae superioris, the superior rectus, the medial rectus, the inferior rectus, the inferior oblique, the lateral rectus and the superior oblique. Several combinations of several muscles showed the existence of double labeled neurons in the trochlear nucleus and the accessory abducens nucleus.抄録全体を表示PDF形式でダウンロード (4253K) -

ジャーナル フリーSummary: The subcortical afferent projections to the nucleus reticularis tegmenti pontis (RT)were identified from the retrograde transport of horseradish peroxidase (HRP). HRP was injected into the medial and lateral parts of the RT, respectively. The major afferent inputs to the RT were found to arise ipsilaterally from the nucleus of the fields of Forel, the medial division of the medial mammillary nucleus, the region lateral to the red nucleus, and the posterior commissural nucleus; contralaterally from the anterior pretectal nucleus, the deep layer of the superior colliculus, and the supragenual nucleus; and bilaterally from the lateral habenular nucleus, the retrorubral nucleus, the central and posterior nuclei of the interpeduncular complex, the gray matter along the floor of the fourth ventricle, and the prepositus hypoglossi nucleus. Regions containing fewer labeled cells included the premammillary nucleus, the zona incerta, the nucleus pontis centralis oralis and the medial vestibular nucleus. In addition, the medial division of the medial mammillary nucleus, the lateral habenular nucleus, the central and posterior nuclei of the interpeduncular complex, and the supragenual nucleus were found to project mainly to the medial part of the RT. The superior colliculus, the retrorubral nucleus and the gray matter along the floor of the fourth ventricle projected mainly to the lateral part of the RT.
These results indicate that the medial part of the RT receives fibers mainly from the diencephalic limbic areas, whereas the lateral part of the RT receives fibers mainly from nonlimbic (somatomotor, visuomotor and vestibular) areas.抄録全体を表示PDF形式でダウンロード (4858K) -

ジャーナル フリーSummary: The microvasculature in the plicae palatinae transversae of the hard palate of the cat was investigated by means of the acryl plastic injection method under a scanning electron microscope (SEM).
On the hard palate of the cat, seven or eight transverse palatine ridges arching forwards were observed. Small digitiform processes were located on the top line of each ridge, and anterior and posterior conical processes were present on both the anterior and posterior slopes of each ridge. The lateral ends of each ridge were observed as simple forms in which these processes disappeared.
The blood supply of the ridges came from the lateral and medial branches of the a. palatina dura major. These branches formed a primary arterial network in the submucosa superficial to the palatine venous plexus. Small twigs were derived from this network to form a secondary arterial network in the lamina propria. Further, arterioles from this network formed a subepithelial capillary network immediately beneath the epithelium. From this net work, capillary loops sprouted into the papillae of the lamina propria. Blood from the subepithelial capillary network drained into the primary venous network in the lamina propria, from which venules drained into the superficial layer of the palatine venous plexus in the submucosa, and then into its deeper layer.
The entire microvascular pattern of the hard palate of the cat was thus investigated and used to assess and confirm the lamina-formation of the palatine mucosa. Regions of thickening such as the transverse palatine ridges of the cat were not formed by thickening of the lamina propria, but by the submucous tissue including the vascular complex.抄録全体を表示PDF形式でダウンロード (6170K) -

ジャーナル フリーSummary: In the central zone of the ventral wall of the mouse laryngopharynx, a fairly large number of taste bud papillae were observed. The epithelial surface of the radix region of the papilla showed microridges of which outlines were not so distinct. As the surface was traced from the radix towards the top, microridges became more indistinct, and in the top region the surface showed honeycomb or relatively smooth appearance. In the interpapillary area of the central zone and in the lateral zone, the surface was covered with distinct microridges. It is suggested that the epithelium in the taste bud papilla represents more advanced keratinization than in the interpapillary area and the lateral zone, and that the keratinization is rather strong in the top region compared with the radix region in the papilla.抄録全体を表示PDF形式でダウンロード (8497K) -

ジャーナル フリーSummary: The appearance and distribution of γ-glutamyl transpetidase(γ-GTP)in the proliferative state of the liver were investigated by the methods of enzyme histochemistry and immunohistochemistry with monoclonal antibodies which specifically react with a heavy subunit of γ-GTP. In the fatal and neontal liver, a positive reaction was observed along the luminal border of the interlobular bile ducts and that of the bile canaliculi in zones 1 and 2of Rappaport. On the other hand, after partial hepatectomy, γ-GTP was localized along the luminal border of the interlobular bile ducts and that of the bile canaliculi in zone 1 of Rappaport. Both the enzyme histochemical and immunohistochemical methods yielded almost the same results for the distribution of γ-GTP.抄録全体を表示PDF形式でダウンロード (9331K) -

ジャーナル フリーSummary: The aberrant right hepatic arteries were observed in three of twenty-eight Japanese anatomical specimens. The occurrence of the aberrant right hepatic arteries were fewer in 252Japanese cadavers studied by Adachi than in 200 American specimens studied by Michels and in 165 American specimens reported by Basmajian. A case of the three aberrant cases had an arterial anastomosis between the aberrant right hepatic artery divided from the superior mesenteric artery and the proper hepatic artery divided from the celaic trunk. The anastomosed case like this has not been reported.抄録全体を表示PDF形式でダウンロード (5491K) -

ジャーナル フリーSummary: Mucous neck cells in the rat stomach which contain neutral mucin were stained with a modified Mayer's hemalum. When alcian blue staining and periodic acid-Schiff (PAS)reaction preceded hematoxylin staining, mucin-containing fundic gland cells could be distinguished in the same tissue sections: surface mucous cells were positive for PAS reaction and/or alcian blue staining, neutral mucin-containing mucous neck cells were stained with hematoxylin, and acidic mucin-containing mucous neck cells were stained with alcian blue. This alcian blue-PAS-hematoxylin staining sequence represents a useful differential staining method for mucins in the gastric mucosa.抄録全体を表示PDF形式でダウンロード (1852K)
