抄録 <p>A rare anomaly of the scalenus muscles is described. In this case, the right scalenus anterior muscle was absent. As a substitute for this muscle, some aberrant muscle slips arose from the lower vertebrae and descended in front of the ventral rami of the lower cervical nerves. These aberrant slips then ran between the ventral rami of the the eighth cervical and first thoracic nerves, and were fused with the right scalenus medius muscle. Thus, the subclavian artery and vein ran in front of the aberrant slips, together with the ventral ramus of the first thoracic nerve. The aberrant muscle slips issued 2 accessory bundles. One bundle ran between the ventral rami of the fourth and fifth cervical nerves and was fused with the scalenus medius muscle; the other bundle ran between the ventral rami of the fifth and sixth cervical nerves and was fused with the scalenus medius muscle.</p>

抄録 <p>The present study showed that many neurons in the adult rat brain possessed a perineuronal sulfated proteoglycan surface coat which reacted to cationic iron colloid and aldehyde fuchsin. This surface coat was stained supravitally with Ehrlich's methylene blue and doubly stained with Ehrlich's methylene blue and aldehyde fuchsin. The surface coat was also stained with Gomori's ammoniacal silver and doubly stained with Gomori's ammoniacal silver and cationic iron colloid. The surface coat was usually expressed together with a nerve cell surface glycoprotein net detectable with lectin Wisteria floribunda agglutinin. These findings indicate that the perineuronal proteoglycan surface coat is identical to Cajal's superficial reticulum and contains some collagenous elements. It was further demonstrated that collagenase digestion erased Gomori's ammoniacal silver impregnation within the perineuronal proteoglycan surface coat.</p>

抄録 <p>The accessory ascending cervical artery (Murakami et al., 1996), which arises from the subclavian artery and ascends between the scalenus anterior and medius muscles, was studied in 87 Japanese adult cadavers (174 sides), with special attention being given to its origin, distribution, and relationship to other arteries at the cervical or scalenus region. In 154 sides (88.5%), the accessory ascending cervical artery was found to originate from the subclavian artery behind the scalenus anterior muscle, and to branch out to the scalenus anterior and medius muscles as well as those entering the 5th and 6th intervertebral foramens along the 6th and 7th cervical nerves. This artery arose independently in 105 sides. The accessory ascending cervical artery issued off or formed a common trunk with the transverse cervical artery and/or costocervical trunk in 49 sides. In cases lacking the accessory ascending cervical artery, it was usually compensated for by the costocervial trunk and/or transverse cervical artery (18 sides). Common trunk formation with the vertebral, internal thoracic, or suprascapular arteries was not observed. The authors suggest that the accessory ascending cervical artery, the transverse cervical artery, and the costocervical trunk should be grouped into one arterial system, a system that may be a remnant of the precostal longitudinal anastomoses of intersegmental arteries of the dorsal aorta behind the scalenus anterior muscle.</p>

抄録 <p>To clarify the involvement of the caspase family in the pathway of NO-induced chondrocyte apoptosis, osteoarthritis (OA) cartilage obtained from 8 patients undergoing total hip arthroplasty were used for histopathological study. Cartilage samples taken from non-fibrillated areas of femoral head resected during surgery for femoral neck fracture were used for comparison. DNA fragmentation of chondrocytes was detected by the nick end-labeling (TUNEL) method. Apoptosis was further confirmed by transmission electron microscopy. The distributions of nitrotyrosine (NT), caspase-3, and -9 were examined immunohistochemically. The populations of apoptotic as well as NT-, caspase-3-, and -9-positive cells were quantified by counting the number of cells in the superficial, middle, and deep layers, respectively. The TUNEL-positive cells were observed primarily in superficial proliferating chondrocytes, clustering chondrocytes, and deep-layer chondrocytes of OA cartilage. Few positive cells were seen in the proliferating chondrocytes in the middle layer. Positive reactions for caspase-3 and -9 were observed in chondrocytes in similar areas. Histological OA grade showed significant correlations with the mean populations of apoptotic chondrocytes (% apoptosis) over the 3 areas. The populations of NT-positive cells (% NT) over the same areas also showed significant correlation with OA grade. Positivity for caspase-3 closely correlated with the OA grade, % apoptosis and %NT. It was concluded that caspase-3 and -9 could play a role in NO-induced chondrocyte apoptosis in OA cartilage.</p>

抄録 <p>The adductor pollicis muscle was studied in fifty hands of Japanese adult cadavers of both sexes. The radial portion of the oblique head of the adductor pollicis muscle has carpal and metacarpal origins and an insertion into the wing tendon of the extensor apparatus. This portion was located dorsal to the palmar metacarpophalangeal articular nerve and superficial palmar metacarpal artery. Thus, the radial portion of the oblique head of the adductor pollicis muscle (more strictly, the slips dorsal to the palmar-penetrating twig of the ulnar nerve) is similar to the palmar interosseous muscles, except that its slips cannot be clearly distinguished from each other.</p>

抄録 <p>The palmar metacarpal arteries in monkey hands were studied. The palmar metacarpal arteries arose from the deep palmar arch or catella palmaris proximalis and descended in the deep palm, forming the catella palmaris distalis at the distal end of the metacarpus. The palmar metacarpal arteries could be classified into four kinds in relation to the interosseous muscles and metacarpal bones: (i) the superficial palmar metacarpal (sM) arteries descending on the palmar surfaces of the interosseous muscles along the metacarpal bones, (ii) the superficial palmar intermetacarpal (sI) arteries descending on the palmar surfaces of the interosseous muscles along the intermetacarpal spaces, (iii) the deep palmar metacarpal (dM) arteries descending deep in the interosseous muscles along the metacarpal bones, and (iv) the deep palmar intermetacarpal (dI) arteries descending deep in the interosseous muscles along the intermetacarpal spaces. These findings largely coincide with those obtained from studies of the human hand by Murakami (1969).</p>

抄録 <p>In the Japanese, Formosan and crab-eating monkeys, the dorsal metatarsal arteries and their lateral distal perforating branches were well developed and supplied, directly or via the catella plantaris distalis, the plantar digital arteries. In the black ape, the plantar digital arteries arose from the medial plantar artery. The plantar metatarsal arteries of these monkeys, including the black ape, arose from the catella plantaris proximalis or deep plantar arch and were classified into the superficial plantar metatarsal (sM), superficial plantar intermetatarsal (sI), deep plantar metatarsal (dM) and deep plantar intermetatarsal (dI) arteries in relation to the interosseous muscles and metatarsal bones. This classification largely coincides with that of the human hand and foot (Murakami, 1969, 1971) and the monkey hand (Nakai et al., 1987).</p>

抄録 <p>Blood vascular beds of fetal, adult and aged human kidneys were reproduced with methyl methacrylate and observed with a scanning electron microscope. The kidney glomeruli, including those from the fetal kidneys, had anastomosing capillaries. The glomeruli in the kidneys of an aged person contained many more capillaries which were much more tortuous than those of the adult and fetal kidneys. Furthermore, it was observed that the glomeruli in the kidneys of the aged person usually received tortuous afferent vessels and frequently emitted multiple efferent arterioles. The glomeruli in the juxtamedullary layer of the kidneys of the aged person were rather small in size and contained degenerative capillary networks. This observation suggests that the medulla of the kidneys of the aged is poorly supplied with blood.</p>

抄録 <p>The celiac and mesenteric arterial system including the left gastric, splenic, common hepatic, and superior mesenteric arteries shows various types of origins, courses, ramifications and anastomoses. In order to explain the various expressions of this system, we have proposed a typological model, in which celiacomesenteric arteries develop as paired or bilaterally symmetrical primordial vessels originated from the anterior aspect of the aorta, and these vessels anastomose each other with longitudinal and horizontal pathways. Here, we report 3 unusual cases characterized by arterial rings, formed by the left gastric, left accessory hepatic, proper hepatic, anterior pancreaticoduodenal, and dorsal pancreatic arteries. The dorsal pancreatic and anterior pancreaticoduodenal arteries are located to the right and left of the embryonic pancreas developing in the dorsal mesentery, respectively. Such hepatopancreatic arterial rings simultaneously containing right and left elements can only be explained using our typological model, in which the concept of paired arteries or bilateral symmetry is introduced.</p>

抄録 <p>Erythrocytes in human blood stored for 120 days were collected by centrifugation after dispersion in buffered physiological saline. The aged erythrocytes thus collected were incubated with inosine, adenine, glucose or other media, and their shapes and ATP levels were studied by scanning electron microscopy and a luciferine-luciferase method. The aged erythrocytes incubated in a mixture of adenine and inosine markedly regained their ATP levels, and also showed a marked transformation from spiked spherocytes to normal discocytes. Incubation with inosine alone restored ATP levels of the aged erythrocytes to some extent, but did not result in morphological rejuvenation. Incubation in a mixture of citrate and glucose caused morphological rejuvenation, though it restored ATP levels less effectively than incubation in inosine alone. Incubation with adenine alone neither restored ATP levels nor resulted in morphological rejuvenation of the stored erythrocytes.</p>

抄録 <p>Some rare anomalies of the celiaco-mesenteric system were observed postmortem in a Japanese adult male: a) The left gastric, common hepatic, splenic and superior mesenteric arteries arose independently from the abdominal aorta. b) The anterior inferior pancreaticoduodenal artery of the superior mesenteric artery issued a hepatic artery which ascended along the anterior surface of the pancreas and gave off the right gastroepiploic, right gastric and cystic arteries. c) The common hepatic artery gave off an anastomosing branch to the superior mesenteric artery. d) The left gastric artery gave off the left accessory hepatic artery. e) The splenic artery issued the accessory middle colic artery. f) The left inferior phrenic artery gave off the esophageal branch. These anomalies are discussed in light of a typological system which we proposed in a previous paper for the celiaco-mesenteric system.</p>

抄録 <p>Liquid laboratory waste containing osmic acid and cacodylic acid was mixed with potter's clay or hydraulic cement. The clay-waste product was kneaded into blocks and baked in a klin (1,200-1,400 degrees C). The cement-waste product was allowed to harden into concrete blocks. Some of the baked clay blocks and concrete blocks were ground, and immersed in 1 N NaOH or 10% HCI solutions for 3-6 months. X-ray microanalysis of the dried samples of these solutions showed that no leakage of osmium and arsenic occurred in the baked clay embedding, and that some leakage of these agents occurred in the concrete embedding. The present study indicates that the baked clay embedding method is useful for safe storage of dangerous laboratory wastes. Additional experiments suggested that glass embedding is also useful for safe storage of laboratory wastes or harmful metals.</p>

抄録 <p>Origins and distribution of the human inferior phrenic arteries were studied by dissecting 68 Japanese adult cadavers. The inferior phrenic arteries were usually observed as paired (left and right) vessels. Their origins were summarized as follows: a) the aorta itself (85/138 cases, 61.6%), b) the ventro-visceral arteries (celiaco-mesenteric system of the aorta) including the celiac trunk (39/138 cases, 28.2%) and the left gastric artery (4/138 cases, 2.9%), and c) the latero-visceral arteries (adreno-renal system of the aorta) including the middle adrenal artery (4/138 cases, 2.9%) and the renal artery (6/138 cases, 4.3%). The left and right arteries occasionally originated in common trunk from the aorta, celiaco-mesenteric system or adreno-renal system (22/138 cases, 15.9%). A typological diagram explaining these variations is given. The inferior phrenic arteries, especially the left ones, sometimes issued visceral or esophageal branches. This fact indicates that the inferior phrenic arteries are homologous with the celiac trunk and mesenteric arteries. It is further discussed that the celiac trunk and mesenteric arteries are originally paired vessels, through introduction of our previous typological diagram of the abdominal arteries.</p>

抄録 <p>The plantar metatarsal arteries of some mammals were studied. In the dog, raccoon dog and cat, the second proximal perforating branch was fully developed and produced the plantar metatarsal arteries. These plantar metatarsal arteries ran on the plantar surfaces of the interosseous muscles along the metatarsal bones or intermetatarsal spaces, and gave rise to the digital arteries of the second to fifth toes. In the rabbit, a branch of the medial plantar artery ran transversely on the plantar surfaces of the metatarsal bones at a level distal to the bases of these bones, and produced the plantar metatarsal arteries. These plantar metatarsal arteries ran deep in the interosseous muscles along the metatarsal bones or intermetatarsal spaces, and joined with the digital arteries which were derived from the medial plantar artery. The plantar metatarsal arteries could be classified into four kinds of arteries (sM, sI, dM and dI) in relation to the interosseous muscles and metatarsal bones. This classification largely coincides with that of the human hand and foot (Murakami, 1969, 1971), the monkey hand and foot (Nakai et al., 1987; Hinenoya et al., 1987), and the forepaws of some animals, including the dog and cat (Murakami et al., 1987).</p>

抄録 <p>The interosseous and lumbrical muscles in twenty-five hands of Japanese adult cadavers were dissected. The palmar and dorsal interosseous muscles continued, with few exceptions, into the wing tendons. The dorsal interosseous muscles gave off tendons which pierced the transverse laminae or passed deep to the transverse laminae, and attached to the bases of the proximal phalanges. The palmar interosseous muscles seldom had such attachments. The palmar and dorsal interosseous muscles sometimes gave off additional tendons which passed superficial to the transverse laminae and attached to the bases of the proximal phalanges. These latter attachments were typical in the contrahentes muscles. Thus, the present findings suggest that the human dorsal interosseous muscles are composite muscles derived from the dorsal abductor, flexor brevis and contrahens muscles, and that the human palmar interosseous muscles are composite muscles derived from the flexor brevis and contrahens muscles. The lumbrical muscles rarely gave off accessory slips with atavistic attachments to the proximal phalanges.</p>

抄録 <p>The deep palmar muscles in monkey hands were studied. The contrahentes muscles mainly arose from the capitate bone, descended palmar to the deep palmar branch of the ulnar nerve and the palmar metacarpophalangeal nerves, and attached to the proximal phalanges or wing tendons of the second, fourth and fifth fingers. In relation to the deep palmar branch of the ulnar nerve and the palmar metacarpophalangeal nerves, the contrahentes muscles are homologous with the adductor pollicis and flexor indicis radialis muscles. The contrahentes muscles occasionally gave off some accessory slips which blended with the interosseous muscles. These findings suggest that the human adductor pollicis muscle is a well-developed remnant of a contrahens muscle, and that the human interosseous muscles contain some remnant of the contrahentes muscle. In fact, a well-developed remnant of a contrahens muscle was found in the fourth finger of a human hand. It is further considered that the human adductor pollicis muscle contains an element of the interosseous muscle of the thumb.</p>
