ジャーナル フリーThe afferent connections of the hippocampus in the rat were examined by means of a retrograde axonal transport method using horseradish peroxidase (HRP). The results were as follows: During injections of HRP in the dorsal or ventrolateral hippocampus, labeled areas did not show any difference, except for the medial septal nucleus. Numerous labeled cells were consistently found in the ipsilateral medial septal nucleus, the diagonal band nucleus, the entorhinal cortex, the locus coeruleus, the dorsal raphe nucleus, the medianraphe nucleus, the posterior hypothalamic nucleus, the supramammillary area, the supraoptic area and, bilaterally, the lateral hypothalamus area. When injections were made into the dorsal hippocampus, HRPlabeled cells of the medial septal nucleus were observed in medial aspect, but injections made into the ventrolateral hippocampus revealed HRP-labeled cells of the medial septal nucleus in the lateral aspect. After injections into the hippocampus, the supraoptic area was labeled, as first reported.抄録全体を表示PDF形式でダウンロード (1480K) -

ジャーナル フリーThe segmental and regional projections of the sciatic, tibial and common peroneal nerves to the substantia gelatinosa of the spinal cord in rats were studied with an acid phosphatase method. Experiments were performed on 42 rats in which, under chloral hydrate anesthesia, the sciatic, tibial and common peroneal nerves were respectively severed. After a survival time of 5-12 days, the lumbosacral segments of the spinal cord were removed and sectioned.
The frozen sections were incubated using a modified version of Gomori's method. The segments of the projections of the sciatic and tibial nerves to the substantia gelatinosa were located in the L2-S1, region, while the segments of the projections of the common peroneal nerve were from L2, to L6.
The regional projections of the sciatic nerve in the most medial, intermediate and the most lateral parts were found to be at segments L2 - L3, while those for the whole of the substantia gelatinosa were located from L4 to S1. Projections of the tibial nerve for the most medial and intermediate parts were shown to be located at segments L2-L5, while those for the medial parts were shown to be from L6-S1. The regional projections of the common peroneal nerve were fully found in the intermediate parts of all segments.
The above study has provided anatomical data for investigating the mechanisms of somaticosplanchnic interrelations and the principles governing acupuncture anesthesia.抄録全体を表示PDF形式でダウンロード (1578K) -

ジャーナル フリーLocalization of ATP-hydrolyzing enzyme activity at pH 9.0 was examined using rat tail bones which had been treated with the perfusion decalcification technique. The lead citrate methods after Ogawa and Mayahara (1969) or Ando et al. (1981) were used for demonstration of enzyme activity, which was mainly present on the plasma membrane and in the intracellular granules of osteoblasts. Osteocytes and osteoclasts did not have any significant activity. The activity was resistant to EDTA-decalcification and stimulated not only by Mg++ions but also Ca++ ions. Neither levamisole nor sodium fluoride affected it. These findings showed that there was ATP-hydrolyzing activity which was not due to alkaline phosphatase in osteoblasts. Since this activity was stimulated by Ca++ ions, it seems to be identical with so-called Ca-ATPase.抄録全体を表示PDF形式でダウンロード (2760K) -

ジャーナル フリーThe neck region of spermatozoa from the testis and the cauda epididymidis of adult cats were three dimensionally analyzed with an electron microscope. The capitulum consists of a small ventral and a large dorsal portion. The ventral portion is formed after the fusing of longitudinal striated columns 1 and 2, while the dorsal portion, formed of 4+5+6+7in its uppermost end, loses 4 and 7 immediately behind the coalescent knot. The proximal centriole protrudes between 9 and 1+2. The transverse striated columns follow along wall of the proximal centriole. The longitudinal striated columns on the ventral side tend to contact the transverse striated columns on the caudal side, while the longitudinal striated columns on the lateral sides connect with the transverse striated columns on the lateral sides. The ventral portion of the capitulum are coutinuous with the transverse striated columns on the right upper side. Triplets of the distal centriole are not seen in mature spermatozoa. The long axis of the cross section of the flattened head is not always perpendicular to the plane of the central pair of the tail axial filaments, but rotates to both sides within a range of 40°. Ascending toward the head, the two microtubules of the central pair lose the nexin bridge and separate, and their upper portions rotate to both sides within a range of 40°.抄録全体を表示PDF形式でダウンロード (3211K) -

ジャーナル フリーIn order to pursue further the possible localization of the functional centres which belong to the group of the glossopharyngeal, vagus and accessory nerves, the motoneurons of these nerves and their major branches in the rat were examined by the retrograde degeneration method and the horseradish peroxidase (HRP) method.
The results obtained are based on the examination of 62 rats which were divided into five groups. The results obtained are as follows: (A) The vagus nerve arises from 80-90% of neurons of the dorsal motor nucleus of the vagus (DMV), the total neurons of the ambiguus nucleus (AM) except for a few cells occupying the ventral part of its rostral region, the neurons of the reticular formation between the DMV and the AM, and the neurons of the lateral reticular formation ventrolateral to the AM. (B) The motoneurons of the superior laryngeal nerve innervating the laryngeal muscles comprise 20% of the total cells in the DMV and 50% of the neurons in the rostral one-third of the AM, but the motoneurons of the recurrent nerve are present only in the caudal two-thirds of the AM. (C) Fifty to 60% of the neurons of the DMV supply the abdominal organs. The cell mass forms a series of columns, which is located in the lateral part of the rostral region, the central and medial parts of the middle region and the medial part of the caudal region of the DMV. (D) The glossopharyngeal nerve does not arise from the DMV but from the neurons which are located at a more rostral level than the DMV and from the most rostral and the ventro-rostral parts of the AM. (E) The results also indicate that the vagus nerve consists of elements not only from the vagus nerve but also from the internal branch of the accessory nerve. The neurons of the internal branch of the accessory nerve are scattered in the caudal region of the DMV and the AM. The external branch of the accessory nerve does not arise from the DMV and the AM, but from neurons located in the lateral area of the anterior horns extending from the first to the fourth cervical segments of the spinal cord. These findings were consistently ipsilateral to the side operated on.抄録全体を表示PDF形式でダウンロード (3362K)
