JOURNAL OPEN ACCESSSince the fact that microorganisms are found in the carious lesion was pointed by Milleru very early, numerous investigators participating with the problem of the experimental dental caries used to examine the bacteria which they applied for the experiment in a produced lesion. Invasiveness of limitted number of laboratory strains into an unerupted hamster tooth were tested in a test tube containing neutral broth by Hurst et al2) and they found that oral actinomycetes, Lactobacilli, S tr， tococci and Coηmebacteria were able to do this. They also found that the invasion became much easyer under the acidic circumstance and such approved organisms for invasiveness micht be nourished by the dental substance alone. Before this experiment, Gins3) had isolated two filamentous organisms, Leρtothrix fragmentata and actinomycetes , from carious lesion as the real causer of the lesion, depending on the hypo thesis tnat only bacteria which be able to be nourished by dental substance will be capable to commence carious infection. Unfortunately, however, his results were obtained from a very few material. Present experiment was set up to make a better picture of oral bac teria invasive into dental tissues.View full abstractDownload PDF (783K) -

JOURNAL OPEN ACCESSThough in 1907 Oberndorfer described a carcinoid as a tumor originat ing from the argentaffine cells of the digestive tract, it is as yet open to discussion as to its entity and nature. Few reports have been made on the appendiceal carcinoid in Japan. We are taking this opportunity to report a case of appendiceal carcinoid associated with acute inflammation.View full abstractDownload PDF (2073K) -
PRELIMINARY REPORT : CHANGES OF EXFOLIATED NON-MALIGNANT CELLS IN THE GASTRIC JUICETakashi YAMADA, Nobuhisa ASANO1957 Volume 4 Issue 4 Pages 349-357

JOURNAL OPEN ACCESSAlthough rapid progress has been made in the cytological detection of gastric cancer by the use of many procedures such as, the gastric brush , abrasive balloon , lavage with enzymes and "Zell-Tupfensonde" certain disadvantages are yet to be encountered . It is still difficult to collect cells without changes caused by the gastric juice. Improved cell collecting methods and correct diagnosis by exfoliated gastric cells have been investigated by many, but few reports have been published on cellular changes due to the gastric juice alone. We are therefore presenting the following preliminary basic expenments.View full abstractDownload PDF (958K) -

JOURNAL OPEN ACCESSUp to the present, the determination of parathion (diethyl p-nitrophenyl thiophosphate) in water is carried out using the following method, that is extracting parathion by benzene from water, it is reduced to amino compound , diazotized and colored by using N-(1-naphtyl)-ethylendiamin, and then eva luated the developed color, using a photocolorimeter or spectrophotometer. This method is very complicate to carry out in practice, so the authors originated a new simple method applying the ultraviolet absorption of para thion.View full abstractDownload PDF (512K)
