JOURNAL FREE ACCESSPermeation of trypanblue through the oral mucous membrane of mouse was examined by dropping its solution on the surfase of the membrane.
1) 0.5 percent trypanblue solution dyed only the surface of epithelium of mucous membrane after 1 hour dropping
2) When 0.5 percent hydrochloric acid or half saturated sodium bicarbonate was added to the solution, it permeated through the mucous membrane and reached the submuocsal tissue after 1 hour. And when hyaluronidase was added, the solution permeated through the membrane after 30 minutes.
3) The wall of the excretory ducts of oral glands allowed the dye solution to permeate through the membrane more easily than other parts.View full abstractDownload PDF (8098K) -

JOURNAL FREE ACCESSThe distribution and concentration of glycogen in the epithelium of the oral cavity were investigated histochemically in mice from the later embryonic stage to the end of the weaning stage with special reference to diminution of glycogen in relation to histological differentiation of this area. The principal results may be summarized as follows.
The most abundant glycogen is found in the last embryonic stage in almost all areas. Among each area the hind part of the palate and the dorsal surface of the tongue contain the minimum glycogen at that time. Generally glycogen in each area diminishes remarkably during several days after birth and disappears almost completely in the age of the third week: that is, immediately after the lactation period. As to the time of outset of its diminution, a certain difference is found amog each area of the oral cavity; it begins most early in the front half of the lower lip, the palatine rugae, hind part of the palate and the dorsal surface of the palate and the dorsal surface of the tongue, but a little later in the labial epithelium, from which the dental lamina arises, the disintegrating epithelium of the labial lamina, the hind part of the floor of mouth, the greater part of the base of tongue and latest in the hind part of the lip, a certain median region of the labial lamina, that part of the gum, from which the molar dental lamina arises, the lowest of the naso-patatine canal, and some parts of the cheek surface.
These diminutions of glycogen are frequently accompanied by such differentiations of the epithelien as flattenning of the peridermal epithelium, preceding cornification, diminution of the epithelial layers in number or growing of the germinal layer to regular form (following completion of the stratified squamous epithelium), while in some parts no relation can be demonstrated between morphology of the epithelien and diminution of glycogen in them.View full abstractDownload PDF (3226K) -

JOURNAL FREE ACCESSCertain forms are clinically found in cases of actinomycosis, namely acute, Subacute and chronic forms. 29 Strains were isolated from the patients suffering from. Actinomycosis of such clinically diffsrent forms and their morphological, cultural and serological properties were examined. But the types corresponding to the clinical were not distinguished among the strains.View full abstractDownload PDF (352K) -

JOURNAL FREE ACCESSThere is so-called “Shibi-Gatchaki” spreading, one of endemic nutritional dystrophy, all over the North Tsugaru District of Aomori Prefecture. 1, 350 School children in this area were examined on oral cavity and the results were as follows.
1. Frequency of malocclusion was relatively high and particularly diastema was most remarkable (malocclusion 50.0 %, diastema 26.0 %).
2. Percentage of dental caries was remarkably high (91.3 %).
3. Frequency of dental deposit was comparatively high (68.1 %).
4. Ptyalism was found in 15.9 of children and many of them seemed to have a tendency to sympathicotonia.
5. Frequency of perleche was extremely high (75.8 %).
6. Changes of oral soft tissues were found in plenty as a whole and frequency of glossitis was the highest in them (glossitis 46.7 %, gingivitis 30.5 %, cheilitis 16.3 %, Stomatitis 3.2 %).
Generally speaking, influence of so-called “Shibi-Gatchaki” was not so remarkable on the hard tissues of oral cavity as on the soft.View full abstractDownload PDF (1085K) -

JOURNAL FREE ACCESSTeeth with various degrees of looseness were moved continuously 10 times and the difference of looseness before and after the movenment was studied comparatively. The movement was given by a dental pincette placed on the cutting edge of tooth in such a degree as caused no ache, For the measurement of looseness, a specially devised appliance for this purpose was used.
1) After trials of 10 times movement, it was noticed that the degree of looseness became greater and increase of the degree of loosenes was inversely proportional to the amount of the bone surrounding the root.
2) There are other factors such as periodontal membrane and a part of gum tissue which take part in the speed of increase of looseness than the alveolar bone.
3) The more toughness of the surrounding tissues (perioeontal membrane and gum) takes part in looseness ofittooth, the less alveolar bone exerts influence upon it.View full abstractDownload PDF (4316K) -
