    Candida albicans was selected as a object of investigation at first. Isolation of candida from oral cavity was done and 21 strains of candida were isolated from oral cavity of 100 healthy persons (male 58, female 42).
    In 21 strains, 18 were candida albicans, 1 candida tropicalis, 1 candida Krusei and candida parakrusei. Accordingly candida was found at the rate of 21 %(male 12%, female 33.3 %).
    And then biological relation between candida albicans and lactobacillus was studied with following results.
    1) Candida albicans promoted the growth of lactobacillus and its acid production.
    2) Filtrate of culture fluid of lactobacillus promoted the growth of candida albicans.
    Now it has been known that phosphate promotes the growth of candida albicans. So that the influence of dental cement which contains phosphate upon candida albicans was examined and it was found that dental cement promoted markedly the growthof candida albicans.

    Influence of Communin (culture filtrate of Bacillus coli) on the inhibitory action of saliva on Staphylococcus aures was examined with following results.
    1) Human saliva was possessed of the sightly inhibitory actionon Staphylococcus aureus.
    2) The inhibitory action of human saliva was increased by subcutaneous injection of Communin and the action was the strongest in the 24 hour's saliva after Communin injection.
    3) Rabbit's saliva was also possessed of the inhibitory action and it was increased by Communin injection. The same facts were observed in rabbit's serum and its action was stronger than that of saliva.
    4) The inhibitory action of both saliva and serum was increased parallelly by Communin injection.
    5) The inhibitory action of the both was decreased parallelly by blocking the reticuloendothelial system of rabbit.
    6) Decrease of the inhibitory action of the both by blocking was recovered parallelly by Communin injection to some extent.

    This instrument is designed to contribute to anthropological studies or various other studies related to facial development by determining the condition of development of the body outline. It is worked by sliding a slider connected to a pantograph in a given direction over a person's portion to be described, thereby giving a full-size projection. This instrument is arranged so that a section crossing any point, i e. any facial curve, either vertical or horizontal, can be obtained. Besides, this instrument can be used not only as a cephalometer but also as a craniometer.

    Into the 0.100-0.033 mol solutions of NaF, KF, and NI-14F each, I put rhinogobius similis Gill, tadpole and tubificidae, and measured the lethal time of those animals respectively. Between these measurements and the concentrations of those fluorides mentioned above I could verify the existence of Ostwald's equation of toxic action, and found the equations concerned by the method of the least squares, whose constant numbers were further pursued and investigated comparatively. Though the toxicity of fluorides (NaF, KF, NH4F) on rhinogobius similis Gill, tadpoles and tubificidae is varied according to each fluoride and to each animal, generally speaking, the toxicity of fluorides, with the exception of NH4F, was observed to act the strongest on. tubificidae

  • Report I. On the relation between root surface area and occlusion power of teeth

    Studies were made on the relation between root surface area and occlusion power of teeth. And it was found that each ratio of occlusion power of the first premolar, the first and the second molar to that of medial incisor was closely approximate to each ratio of root surface area of the first premolar, the first and the second molar to that of medial incisor. From the above mentioned facts it is conceivable that the occlusion power of tooth is closely related with its root surface area.
