ジャーナル オープンアクセスA report is made of a case of rupture of intracranial aneurysm by angiography which was done four hours after the subarachnoid hemorrhage. This is a twenty-eighth reported case of the ruptured aneurysm by angiography. The criteria of this complication are presented. The cause and mechanism of this complication (especially vasospasm, change of intraarterial pressure and peeling out of the thrombus) is discussed. Clinical factors of this complication are shown by summarizing previous reports. Cerebral angiography within a few hours after subarachnoid hemorrhage is very dangerous although it is said that angiography should be done as early as possible.抄録全体を表示PDF形式でダウンロード (1086K) -

ジャーナル オープンアクセスDuring the last decade underwater habitations have been planned and carried out in several countries. In Japan, an underwater habitation of 60 meters by 4 men for 7 days (named “Seatopia” project) was carried out by the Japan Marine Science and Technology Center (JAMSTF.C) in 1973. Before the actual project, safety check of the equipment and selection of candidates were required from the viewpoint of medical sciences. After that, 7 subjects, candidates for “aquanauts” lived in a hyperbaric chamber of 7 atmosphere absolute pressure air and helium simulating an underwater habitat of 60 m depth, for 7 clays (in total 15 days including 3 clays of control before compression, 3 clays of decompression, 2 clays after decompression). Physiological functions of all the subjects were examined for more than 2 weeks. Effects of high pre3sure and thermal conductivity on cardiorespiratory system, renal function and metabolism were evaluated with the findings of 1) decreased heart rate and forced expiratory volume; 2) increased urine volume; 3) decreased rectal and skin temperature with increased heat production and 4) the more trained the diver, the lower the skin temperature and the lower the heat production.抄録全体を表示PDF形式でダウンロード (1792K) -

ジャーナル オープンアクセスThe object of this study was to know what changes take place on the buccal segment during the period of change of dentition, and the following conclusions can be made from its result. 1) The space for the alignment of the permanent buccal teeth changes during the period of change of dentition in buccal segment. The main increase of this space occurs during the period of eruption of the permanent canine and some of the permanent first premolar. These kinds of increase make it possible for the permanent canine and the permanent first premolar to align normally. The main decrease of this space takes place through the replacement of the deciduous second molar by its predecessor. 2) As the permanent canine positions more mesially than its predecessor, the permanent first molar is able to migrate mesially more than the amount of the leeway space between the crown diameters of the deciduous buccal teeth and those of their permanent successors. 3) The leeway space is not always necessary for the permanent buccal teeth to align, and it is a part of available space for the alignment of the permanent buccal teeth.抄録全体を表示PDF形式でダウンロード (3724K)
