JOURNAL FREE ACCESSMany studies have been done on the cause and therapy of so called “Pyorrhea Alveolaris”, but its cause is not made clear yet. I studied on this problem from the point of respiration of the tissue.
For the method of measuring O2 consumption of the tissue, the Warburg's manometric technic has been usually used, but I made experiment by using the Oxigraph, by which soluble amaunt of O2 in solution is polarographically measured by means of the minute platinum electrode.
Gums of rats, dogs, and adults were used as materials of the experiment.
In the normal tissue, there was not much difference among the three species.
In the dog's tissue with acute inflammation caused experimentally, slight decrease was found comparing with the control case.
In the tissue of chronic inflammation of patients “Pyorrhea Alveolaris” the marked decrease of O2 consumption was observed.View full abstractDownload PDF (7310K) -

JOURNAL FREE ACCESSIt has been already published in my former paper that there is some relation between the administration of antibiotics and the increase of B. sutilis varietas niger in oral cavity. If it is correct that the black tongue is caused by the increase of B. subtilis var. niger, there would be one reason in supposing that there might be, in oral cavity, some microbe which, in normal time, suppresses the growth of B. subtilis var. niger and is sensitive to antibiotics, but, I have found that, as the result of my examination on various microbes in oral cavity, the microbe in question is some kinds of lactobacillus. By some kinds of lactobacillus, I mean Lactobacillus casei, Lactobacillus plantarum, Streptococcus faecalis, Lactobacillus faecalis. I examined the sensibility of the above four to antibiotics by cup method, and found that their sensibility are far bigger than that of B. subtilis var. niger, although the sensibility varies more or less according to the kind of lactobacillus and the kind of antibiotics used. Further, I measured the number of lactobacilli in saliva, using penicillin in a clinical way, and I found, after a certain time, that, 1) it decreases remarkably when penicillin cone is inserted or gargle with penicillin water, and, 2) when oil penicillin is injected intramuscularily, it decreases in some cases and does not decreas in other cases.
From the above mentioned facts, I am of an opinion that the black tongue, which occurs in case antibiotics are used, is caused by alternation of microbe between B. subtilis var. niger and lactobacillus in oral cavity.View full abstractDownload PDF (10116K) -

JOURNAL FREE ACCESSConsidering that there would be some relation between progress of pyorrhea alveolaris and vitality of parodontium, we studied on katalase, one of the necessary ferments to human body, in pyorrheal gingiva. The results were as follows.
1) Katalase activity of pyorrheal gingiva was less than 2/3 of normal gingiva.
2) Stronger the inflammation or deeper the gingival pocket, less the katalase activity.
It seemed that katalase activity of pyorrheal gingiva was inversely proportional to the progress of pyorrheal condition.View full abstractDownload PDF (912K) -

JOURNAL FREE ACCESSTo study the influence of Parotin (salivary gland hormone) upon wound healing, the same size of back skin was removed respectively from 6 groups of rabbits and the area of each wound was measured from day to day with following histological examinations, in comparison between the Parotin injected groups and the non-injected control group. Parotin was injected 0.1 mg./Kg. daily to the 1 st group, 0.2 mg./Kg. daily to the 2 nd group, 0.3 mg./Kg. every other day to the 3 rd, 2.5 mg./Kg. every other day to the 4 th, 0.5 mg./Kg. once a week to the 5 th. The 6 th group was not injected as control.The results were as follows.
1) Wound healing was most accelerated in the group given the injection of 0.2 mg./Kg. Parotin daily.
2) Histological examinations showed that in the Parotin injected group fibrougrowth of fibroblasts was more accelerated, and regeneration of capillar vessels moractive than in control.View full abstractDownload PDF (4497K) -

JOURNAL FREE ACCESSThe most favorable operation method for cleft palate is now regarded as to be the push-back operation aiming at the stricture of cavum nasopharyngis.
However. even with this method, cicatricial contraction after the operation necessitate often subsequent pharyngeal flap operation in the patients with wide cleft and large space between uvula and pharyngeal wall.
In order to eliminate this shortcoming, it is to pick up the combined use of the push-bach and pharyngeal flap procedure (the one stage operation).
In comparison with the two stage operation, this procedure has following various merits:
1) the formation of pharyngeal flap being easy.
2) the fixation of transplanted pharyngeal flap being easy.
3) the percentage of successful case of transplantation being high.
4) cicatricial contraction being slight.
Moreover, considering from our clinical experimences, it is regarded as follows:
1) Cavum naso-pharyngis becomes narrower about one tenth than that before the operation.
2) Pronounciation is remarkably improved.
3) This operation will be indicated for children over 5 years of age.View full abstractDownload PDF (2322K) -

JOURNAL FREE ACCESS1) Aminoacids in dental calculus obtained from patients with alveolar pyorrhoea were examined by the method of partition paperchromatography.
2) These aminoacids were following ; cystine, aspartic acid, glutamic acid, serine, glycine, threonine, alanine, tyrosine, lysine, arginine, proline, valine, methionine, phenylalanine, leucine, etc.View full abstractDownload PDF (435K) -

JOURNAL FREE ACCESSA pathohistological investigation of dental pulps of non-carious teeth in various conditions was performed. The results were as follows.
1) Six dental pulps in 20 intact teeth showed nearly normal appearance and others showed certain degenerative signs.
2) In 31 pyorrheal teeth, 1 pulp was inflamed, 1 was nearly normal, and others showed degenerative changes.
3) No apparent sign of inflammation was observed in 23 dental pulps of lower -third molars accom panied by pericoronitis. Thirteen showed nearly normal appearance or slight degenerative signs, in 6 apparent degenerative changes were observed, and 4 were congested.
4) In 50 teeth in the area of jaw bone, that was once acutely inflamed, 13 dental pulps were apparently inflammatory, in 4 bleeding was observed, in 10 slight cell infiltration arround blood vessels, and 23 showed degenerative changes.
5) Many dental pulp stones were found in the pyorrheal teeth and in the teeth of the 4 th group. Some of them may have relations to infection.
In view of these results, it is conceivable that even though the teeth in the area of jaw bone, that was once acutely inflamed, are not carious, a majority of them would be infected. Therefore we have to watch them strictly, and they must be under timely treatment at a proper time.View full abstractDownload PDF (16386K) -
. Part II. Effect of GarglingTatsuya Okumura1955 Volume 4 Issue 4 Pages 338-343

JOURNAL FREE ACCESS1) To determine the effect of gargling with D. H. A.-salt as well as with other gargles, the writer examined the changes in the count of acidogenic bacilli both in the disgorged fluids obtained from gargling, and in the mouth after continuously repeated gargling, with each of those solutions.
2) As for the count of acidogenic bacilli in 40 c. c. of each disgorged fluid, the number of bacilli was less in the cases of D. H. A.-salt solution than in those of physiological salt solution or of boric acid water, so that D. H. A.-salt seems effective tosome extent.
3) The cases of D. H. A.-salt solution showed lower value than those of boric water concerning the number of bacilli in the disgorged fluids obtained from the first gargling, after which, however, the former cases attained the highest one.
4) As regards penicillin and aureomycin, the bacilli were scarcely demonstrable in the disgorged fluids obtained from the first gargling, nearly all the cases, however, showed the development of bacilli in the disgorged fluide obtained from the gargling with physiological salt solution only 5 minutes after the last gargling.
5) The increase of bacilli number after continuously repeated gargling is not al ways proportional to the course of time, showing considerable differences in fluctuation.
6) The gargling with D. H. A.-salt solution seems unpromissing to be expeeted much of its effectiveness, and penicillin seems to show a good result.
7 The effect will be due not much to the chemical work of the gargles themselves, but a great deal to their mechanical one.View full abstractDownload PDF (730K) -
