JOURNAL FREE ACCESS1. The neocortex was markedly reduced in area and size. 2. The hippocampal cortex was fairly well preserved and the dentate fascia showed a marked degree of overgrowth in this case. 3. The globus pallidus and the putamen were relatively normal. 4. No caudate nucleus was noted in this case. 5. The thalamus was atrophic and the entire hypothalamus was dysplastic. 6. An absence of the pulvinar and the pretectal nuclei was noted in this case. 7. A poorly differentiated pars dorsalis of the lateral geniculate nucleus was noted. 8. A relatively normal medial geniculate nucleus was noted. 9. The subthalamic nucleus of Luys was present. It was larger than normal, and showed evidence of a marked degree of overgrowth. 10. The red nuclei were relatively normal, but were noticeably larger than in the normal state. The substantia nigra was present and was relatively normal. 11. In the present case of hydranencephaly relatively normal structure could be noted in the basal ganglia, cerebellum, brain st e m, tegmentum, and the medulla. 12. There was noted an absence of the pyramidal tract; this fiber tract being completely hypoplastic.View full abstractDownload PDF (5919K) -

JOURNAL FREE ACCESSMethylene blue clearance p reparations of 422 externally normal embryos were examined for study of individual difference in chondrification. These human embryos, at stages ranging from 13 to 23 of Streeter's horizon (5.1 to 30.5 mm crown-rump length), that is, at five to eight weeks postconceptional age, were obtained from healthy pregnant women subjected to induced abortion by curettage. The stage of the onset of cartilage centers w hich appear in 100% by horizon 23, will be mentioned in the sequence of the stage of the first appearance: The cartilage centers of the humerus appear between horizons 16 and 18. Those of the 1st ribs, vertebral bodies, radius, ulna, and metacarpals appear between horizons 16 and 19. Those of the presacral vertebral arches, scapula, carpals, proximal phalanges of the hand and pelvis appear between horizons 16 and 21. Those of the metatarsals appear between horizons 16 and 22. Those of the 2nd-6th ribs, femur, and tibia appear between horizons 17 and 19. Those of the 7th-9th ribs and fibula appear between horizons 17 and 20. Those of the 10th-11th ribs appear between horizons 17 and 21, and the 12th ribs between horizons 17 and 22. Those of the proximal phalanges of the foot and calcaneus appear between horizons 17 and 23. Those of the Meckel's cartilage appear between horizons 18 and 22, and of the tarsus between horizons 18 and 23. Next, the stage of the first appearance of the cartilage centers which appear only occasionally by horizon 23 will be given as follows : the occipital arch and distal phalanges of the hand, 16 ; the middle and distal phalanges of the foot, 17 ; the squamous of the occipital, 18 ; the malleus, styloid process, temporal (greater) wing of sphenoid, nasal, and cricoid, 19 ; the supraoccipital, 21. The above mentioned data differ somewhat from the findings of the previous investigators. Moreover, 37 embryos with asymmetry, regarding the appearance of some cartilage centers of bilateral pair were found. The incidence of the 7th cervical rib was 7% in horizon 19, 32% in horizon 20, 37% in horizon 21, 34% in horizon 22, and 30% in horizon 23. The 7th cervical ribs, when present, were usually bilateral. The lumbar rib (unilateral or bilateral) was observed on the incidence betweeen 4% and 7% at horizons from 19 to 23.View full abstractDownload PDF (4694K) -

JOURNAL FREE ACCESSThe fixation effects of d i methylsuberimidate (DMS) and other diimidoesters, which react with amino groups of proteins and cause the intra- and intermoleculer cross-links of proteins, were investigated, in order to develop the fixative which is expected to be suitable for the histochemical study. Before applying these reagents to histochemical study, a comparison was made with glutaraldehyde about the preservation of fine structures of various organs. The ultrastructure of liver, kidney, small intestine, lung, pancreas, striated muscle, cardiac muscle and testis was preserved very well after the fixation with DMS, and did not show much noticeable differences from that with glutaraldehyde fixation. Since DMS worked very well from the morphological standpoint, and since DMS is known to cross-link the proteins safely from the biological data, this reagent is now ready for tentative application for histochemistry as a fixative.View full abstractDownload PDF (9482K) -

JOURNAL FREE ACCESSThe purpose of this study was the determination of the normal condition of the Mm. interspinales of the Japanese by the examination of a comparatively large number of cases (30 bodies,60 sides), and the results of the examinations were processed statistically. The Mm. interspinales of man consist of the Mm. interspinales cervicales, the Mm. interspinales thoracales, the Mm. interspinales lumbales and the M. interspinalis sacralis.View full abstractDownload PDF (1981K)
