ジャーナル フリー1) It has been evidenced in our animal experiments with matured rabbits that both autogenous and homogenous grafts are gradually absorbed whenever they are transplanted in any portion of the body if there are no physiological demands for the bone.
2) Autografts showed much better affinity with the tissue than heterografts. Albeit the less affinity of the latter, their attitude was by no means synonymous to the attitude of the sequestra, and their intolerability was gradually reduced with the lapse of the time. This phenomenon was not altered by either hemotype or salivary type.
3) In the case of homografts, the. attitude of the grafted bones was modiffed by preoperative serological preparation:
A. Previous injection of serum from the homogenous donator effected the maintenance of relatively physiological state on the grafted bone, whereas same procedure with serum from those homogenous or heterogenous species which are not the donators induced a trend toward marked absorption of the grafted bone.
B. There was a less absorption of the grafted bone in those which had previouslyundergone injection of serum of homogenous donator than in those which had not.
C. It was also noted that there was the most remarkable trend toward degenerative necrosis in those which had been previously treated by heterogenous serum injection. No relationship was found between these results and title of produced antigen or antibody.抄録全体を表示PDF形式でダウンロード (16773K) -

ジャーナル フリーI obtained a most excellent result with the periodic acid Schiff reaction for the determination of the polysaccharides in human gingiva. Better results were obtained with periodic acid sodium or kalium for oxidization than with periodic acid, Weigert's haematoxylin being perferable for nuclear staining, and Orang G for a counterstain. Carnoy and absolute alcohol is best for tissue fixation, but buffered formalin is also usable.
The periodic acid Schiff reaction shows the distribution of the polysaccharides to various degrees through out the gingiva epithelial cells, and the stainabily can be made to diminish or disappear, by the Amylase digests technic.
Also there is a close relationship between various degrees of inflammation of the gingiva, and the polysaccharides of the epitheral cells.抄録全体を表示PDF形式でダウンロード (7841K) -

ジャーナル フリーWhen the cathode ray luminescence of samples of varied types of teeth taken from alveola suffering from pyorrhea and of tartars accumulated on such teeth was examined, it was found that not only the crowns of the affected teeth, but also the roots exposed above the aveola and the root surfaces touching the inflammatory granulation tissue gave always bright red (27 na. 7) or reddish (27 ea. 7) luminescence, due to the quantity of the trace metal element Bi present. The special selective action of the epithelial cells due to the disturbed metabolism of mineral substances accompanying their retrogressive degeneration, the pathogenic factor of pyorrhea, is responsible for such results.
Inflammation induced by mastication pressure and by bacilli and tartars may be mensioned as the probable factors of such disturbances.
The presence of the trace mineral Bi seems to play an especially important part in causing precipitation of dystrophic calcium compounds.抄録全体を表示PDF形式でダウンロード (5685K) -

ジャーナル フリーDisinfection of dental instruments (such as root-files, reamers, broaches, cleansers, etc.) for the treatment of root-canal is very necessary. Brody and Nishizuka reported this in the literature many years ago. As we often find rust in various dental instruments when they have been kept under disinfected condition on account of the materials of these being made of iron, we consider that the most convenient method to keep these instruments under the complete disinfection as well as rustless condition should be considered in view of the clinical and scientific object. As regards this subject, we have undertaken bacteriological, biological and physical experiments, and found that the solution prescribed below is most likely to be appropriate.

When many dental instruments are sufficiently disinfected by immersing them in the above solution for more than five minutes, a complete disinfection can be attained without affecting them with rust, nor it makes these instruments irritant to oralmucous membrane. This disinfectant is very convenient for the daily use of dental. treatment.抄録全体を表示PDF形式でダウンロード (929K) -

ジャーナル フリーThere were descriptions given in 1927 by Bauer and by other dentists in later years regarding the relation of the fracture of the roots and cementum tears. But the reports concerning the so-called pyorrhoea cannot be found as far as I know. The traumatic occlusion is recognized as an important factor in the formation of cementum tears and is regarded as one of the causes of the so-called pyorrhoea. Consequently, I have examined the appearance of cementum tears in the lower jaws because I thought I would be able to discover them more readily at that location.
The tears hardly are found roentogenologicaliy, but they can be discussed histologically.
I have found the traumatic occlusion in all cases where cementum tears have appeared. On the other hand, I have hardly found the traumatic occlusion in cases where the cementum tears have not appeared.
In the area of the teeth examined the frequency of the appearance of the tears are found most in the molar teeth, the anterior teeth and the premolar teeth respectively.
The relation between the appearance of cementum tears and sex and age cannot be determined because of the lack of cases examined.
Briefly the appearance of cementum tears in the so-called pyorrhoea alveolaris has a close relation with traumatic occlusion.抄録全体を表示PDF形式でダウンロード (3462K) -

ジャーナル フリーThe author's original object was to photograph all shallow cavities of the body, but for the convenience sake, the oral cavity was chosen for the present study.
The routine method now in general use is to approximate a camera close to the mouth. But both the camera and light source are kept outside the mouth, and a mirror is used to reflect the hidden part of the tooth. It is impossible by this method to photograph the part which can not be seen by the naked eye, and the picture taken by this method has not so much practical value unless it is unexceptionally clear.
To remove defects which are found in all the hitherto used methods, the author devised a miniature finger-shaped camera which is very convenient for oral photography. It is 24 cm long, 13 cm and 8.8 cm in inner and outer diameters, respectively. The light source consists of the two tiny electric bulbs of A. C. 100 V and 37 V, respectively (one is supplementary). The film is 6 mm wide and 150 mm long. This eamera can directly be placed into the mouth, and pictures taken with this are highly satisfactory.
The function of this camera has its limitation due to the miniature shape, but all the possible improvements seem to have been made within this limitation.
Also the author devised another type with different construction and function. This is composed of a 35 mm Leika-type camera which is kept outside the mouth, and an endoscope-like attachment provided with a prism and flash lamp which is placed into the mouth to take the inner view. The attachment is adjusted to the site to be photographed directly by the eye_ Thanks to the completion of this method, all the teeth, various states of oral mucous membrane can be observed exactly through the photograph. Also any body cavity in which the attachment can be inserted can be photographed. Further, it is easy to take color photograph.
Consequently it has become possible to make diagnosis, to trace the course of illness and to know the effect of therapy more exactly than before.
Pictures taken with this camera can provide objective data for study and useful materials for education.抄録全体を表示PDF形式でダウンロード (66589K) -

ジャーナル フリーTo produce resin-like substance from human blood and fromaline as artificial bone, human blood was treated by fromaline, and then gelatinized blood was dried under vacuum. By heating and molding this substance under pressure in a metal mold, resin-like substance was obtained.
The properties of this substance was examined from the stand point of polymer science. As the results, it was possible to produce resin-like substance from human blood and formaline, and the authers called it “blood resin”抄録全体を表示PDF形式でダウンロード (3082K) -
