ジャーナル フリーAttention has been drawn to the localization of the pyramidal tract within the internal capsule of the rhesus monkey. This paper is based on experimens with 8 adult rhesus monkeys. An electrode was inserted stereotactically towards the posterior limb of the internal capsule. Its location at the internal capsule was confirmed by inducing movements of the contralateral forelimb with a current of 1 V or less, and the same site was electrocoagulated. Following the operation, the right upper extremity of the experimented animal revealed a characteristic transient paresis. Histological observations indicated that the pyramidal tract which projected the upper limb occupied the anterior third of the internal capsule. However, this conclusion is only acceptable at the horizontal level of the superior limit of the thalamus, since the pyramidal tract changes anatomical location within the posterior limb as it courses through the internal capsule.抄録全体を表示PDF形式でダウンロード (2756K) -

ジャーナル フリーThe structure and variations of the circle of Willis in 55 days were studied from corrosion-cast specimens. The perivascular sympathetic innervation of the circle was also investigated in 9 dogs using the Schultz silver impregnation method. The following results were obtained.
1) The circle was entirely closed in all specimens.
2) The basic shape and variations of the circle were briefly as follows. (i)The connected shape of the bilateral anterior cerebral arteries could be classified into three types?having a common trunk (87.3%), having a single anterior communicating artery (9.1%) and having a double anterior communicating artery (3.6%). (ii) Asymmetry of the diameter of the anterior cerebral artery was found in 14.5%. (iii) Button-hole formation was observed in 1 case (1.8%) in the posterior part of the circle on each side.
3) The patterns of divergence of the main cerebral arteries which arose from the circle were as follows. (i) The divergent patterns of the internal carotid artery could be classified into five types. The most general was a pattern which first gave off the posterior communicating artery, and secondly divided into the middle and anterior cerebral arteries. Such cases were found in 85.5% on the right side and 81.8% on the left. (ii) The position of origin of the anterior choroidal artery was from any of three arteries-the middle cerebral (right: 69.1%, left: 67.3%), the posterior communicating (right: 20.0%, left: 23.6%) and the internal carotid artery (right: 10.9%, left: 9.1%). (iii) Double posterior cerebral and anterior: cerebellar arteries were found in 1.8% on the left side for the former and in 1.8% on each side for the latter.
4) The diameters of the main cerebral arteries were measured in 50 dogs and a comparison was made of the diameters of the vessels on the right side with those on the left. In the dog, the diameter of the terminal branch of the basilar artery was slightly larger than that of the posterior communicating artery in 86.0% on the riright side and 94.0% on the left.
5) A correlation existed between the diameter of the posterior cerebral artery and that of the posterior communicating artery, and between the diameter of the pasterior cerebral artery and that of the terminal branch of the basilar artery.
6) The posterior cerebral artery was found to be innervated not by the sympa-155156 K. Tanuma thetic nerve fibers from the stellate ganglion, but by those from the superior cervical ganglion. The derivation of the posterior cerebral artery is discussed from the viewpoint of the perivascular sympathetic innervation in addition to the ontogenic and phylogenetic relations.抄録全体を表示PDF形式でダウンロード (3348K) -

ジャーナル フリーThe subnuclear segregation of the motor trigeminal nucleus in the horse, cow, goat and pig was investigated using Nissl stained serial cross sections of the lower brain stems. The motor trigeminal nucleus in the horse, cow and goat was found to consist of the caudal, dorsal, ventrolateral and ventromedial subnuclei. In the pig, it consisted of the caudal, dorsolateral (corresponding to a union of the dorsal and ventrolateral subnuclei in the other species) and ventromedial subnuclei. All subnuclei were columnar in form, lengthened in the rostrocaudal direction. The caudal subnucleus was the smallest and protruded in the caudal diroction on the medial side of the descending root of the facial nerve. The dorsal subuucleus was the largest, and the nerve cells were somewhat larger and more loosely-arranged than those in the others. The ventrolateral and ventromedial subnuclei except for those of the horse sometimes lacked a gap between them and the dorsal one at irregular levels, although the nerve cells were somewhat smaller and more denselyarranged.
In view of the relation to the somatotopic representation of motoneurons, the subnucleus is considered to innervate the masticatory muscles with the same function, i. e. the jaw-openers and the jaw-closers. In other words, the subnucleus represents a morphological and functional unit.抄録全体を表示PDF形式でダウンロード (2880K) -

ジャーナル フリーUsing a peroxidase-antiperoxidase method, the intracellular lysozyme (LZM) content of human blood cells, salivary corpuscles and nasal discharge cells was estimated after blockade of myeloperoxidase activity. The endogenous myeloperoxidase activity was entirely blocked by 0.3% hydrogen peroxide-methanol treatment in the polymorphonuclear leucocytes.
In the peripheral blood of healthy subjects and various leukaemic patients, mature neutrophilic polymorphonuclear leucocytes and immature ones from promyelocytes onwards were distinctly observed with the immuno-specific reaction. Occasionally, monocytes were also found to contain LZM intracellularly. There was no discernible enzyme in the other blood cell elements.
In salivary corpuscles and nasal discharge cells, neutrophilic granulocytes only demonstrated LZM immunopositively.抄録全体を表示PDF形式でダウンロード (1642K) -

ジャーナル フリーMorphological changes in rabbit articular cartilage induced by joint contracture were studied by light and transmission electron microscopy. The knee joint was plaster-immobilized for 3-9 weeks in the flexion position. Three different age groups of rabbits were examined, i. e. at the age of 1 month (young),1 year (adult), and over 2.5 years (old).
In the non-treated groups, the surface of the articular cartilage of the old rabbit was undulated and less smooth than that of the young rabbit. In the old rabbit, cell density of the articular cartilage reduced, and the filamentous-amorphous surface layer increased in thickness.
In the plaster-immobilized groups, no significant change was noticed in the young rabbit. In the adult rabbit, on the other hand, remarkable changes in the articular surface, and the intercellular matrix occurred after 5-week-immobilization. In addition to those changes, chondrocytes were also affected in the 5-week-immobilized old rabbit. The damaged articular cartilage of the adult rabbit which had been immobilized for 3 weeks recovered, while the old rabbit did not.抄録全体を表示PDF形式でダウンロード (4192K)
