    Results, which are obtained by electrophoretical method, have too many factors to be expressed in a simple manner. At least, three factors must be considered in the explanation of electrophoretic results; they are: 1) there are four or five components to express serum protein fractions (Alb., α-Glob., β-Glob. and γ-Glob) or plasma fractions (serum components plus fibrinogen), 2) electrophoretic pattern must be disscussed from vorious points of view, nomely, an alternation in forms and mobilities from the regular plasma or serum components, or an appearances of unusual component, 3) it is difficult to comprehend the increase or decrease by sinply observing the numerical changes of protein fractions.
    Agogram and Serogram, designed by K. Honda et al and H. Kanagami et al, are new excellent graphical expressions of electrophoretical serum protein components, taking into account factors 1) and 3) mentioned above. We disscussed Hond's Agogram and revised it and designed “Agogram”.
    There are some differencess between these two expressions. a) “Agogram” uses percentage to express the electrophoretic values. Because, we can obtain only percentage of protein fraction directly from the pattern, but not each protein concentration (g/dl) as applied in Agogram. And it is one of the charactsristics of the electrophoresis that we can catch correlational ratios. of protein components. Moreover, it is liable to produce errors to convert percentage of fraction into concentration values of each components. b) Agogram express the values of increase or decrease of components. But normal protein fraction has each different level, and for example, when both φ and γ-Glob. increased 10%, Agogram will express the increase of both components in the same degree, in spite of the fact that percentagec in increase in φ-component is much larger than that in γ-Glob. Accordingly our “Agogram” expresses the ratio of increase or decrease calculated by the following formula:
    A-B/A×100=Ratio of increase or decrease
    A: value of normal subjects (%)
    B: value of the material
    We applied this “Agogram” in clinical use together with the electrophoretic pattern and the values of each components, and could make easier and clearer interpretation of the protein fluctuations of pre-and post-operative period, carcinomas and various liver diseases.

    著者は本論文に於てHarknessのplasma protein equilibrium factor K(H)について專ら理論的考察を行い,これに關して論じたことを要約すれば次の如くである。
    (1) K(H)を更に擴張して各分屑を包含せしめ,且その濃度に無關係に%組成のみによつて次の如く規定し得るKを導いた。
    K=aαngααgββgγγffn
    an+α+β+γ+fn}各分屑の正常%=a+gα+gβ+gγ+f}對象血漿の各分屑%=1假に各系が獨立であると假定すると,本川の脳波のエネルギーに用いた論法を借用して次の樣な推論が出來る。即ちyi(i=1~n)の總和が上限Snを有するものとすれば
    SnSni=1yi≧0であつて,n>10の程度では近似的にyixx+dxの間にある確率は
    f(x)dx=1/σe-xdx (7)で與えられ,SSS+dSの間にある確率は
    F(S)dS=n/SnmSn-1dS (8)である。勿論血漿蛋白ではnは小であるが,α或はγが更に幾つかに分別されつつある現在,これ等の和を唯5個に取り出しているものとすれば上のn=10程度の假定を置いても甚しい誤りではなかろう。即yiを各分屑の濃度とすれば,血漿蛋白の總量がSと考えられる。從つて(8)から期望値即正常値Sn
    Sn=∫(9)(10)は成立する。これをPで表わし,P-Pn=Zとすれば,(9)及び(10)は
    f(x)dx=1/√2πσe-Z2/2σ'2d2dZ (9')or=1/√2πe-ZdZ (10')である。從つて或る偏つた分布を取る確率の目度として
    W=Πnei=1-Zi or Πnei=1-Zi2/2σi'2と置けば
    -logWni=1ΔP/Pin or 1/Σni=11/σ'i2(ΔP/Pin)2であつて,吾々のQと同樣な形式になる。若し前者であるならばQとして
    Qa/an+Δα/α+Δβ/β+Δγ/γ+Δf/fn (11)後者ならば
    Q=1/σa2a/an)2+1/σα2(Δα/α)2+… (11')とおけばQはその偏り方の確率の對數にすることになる。

    Measurements of electrophoretic mobilities have contributed much to our understanding of the nature of proteins and other biologically important substances. The techniques usually employed, however, make use of optical methods and require a large amount os substances. so that the method cannot at present be generally used.
    In this paper an attempt is described to determine electrophoretic mobilities at low concentrations. Mobilities can be caluculated by determining average concentrations of solute in upper (ascending) and lower (descending) limbs by appropriate analytical methods after the isolation of the four sections of ordinary Tiselius-type electrophoretic cell.
    Mobilities of desoxypentose nucleic acid of herring sperm were measured in phosphate buffer at pH 7.7 and ionic strength 0.2 in concentration range 0.5-0.005% by measuring ultraviolet absorption at 258mμ and found to be about -16×10-5cm2/sec. volt, which agrees very well with those obtained by an optical method. In the case of E. coli bacteriophages T3 and T4, measurements were made at concentrations of about 107-108 phages/cc (about 10-6%) by determining the number of phages by a plaque method and found to be about -5×10-5cm2/sec. volt.
    It may be concluded that this method is very useful especially in biological studies, though the errors are still larger in these experiments than in the usual optical electrophoretic measurements.

    1) Employing Heiderberger's method, the author studied quantitative precipicin reactions in electrophoretically simple antigen systems, (yeast polysaccharide, crystalline hens egg alubumin, crystalline horse serum albumine, bovine serum and pseudoglobulin, bovin thyroglobulin and Proteus X19 Systems).
    2) The antibody/antigen ratio in equivalence zone obtained by the immunological method by means of succesive injection of a small quantity of antigen, was higher than that obtained by the normal immune method.
    3) The reaction equations were characteristic in each of the antigens, I was able to divide them into polysaccharide, albumin, globulin and bacteria systems.
    Generally, the ratio AbN/Ag N in the precipitate in equivalence zone showed a tendency to be larger the larger the molecular wight of the antigens.
    4) Calculating the molecular ratio of specific precipitate in equivalence zone, by means of antibody N/antigen N which I measured, and also using the known molecular weight of antigen and antibody, we obtained the following results,
    Crystalline hens egg albumin 2.7
    Crystalline horse serum albumin 4.6
    Bovine thyroglobulin 12.2
    5) I found that antibody quantity calculated by quantitative precipitin method agreed with antibody quantity calculated by electrophoretic method, and we measured antibody quantity in immune serum globulin by two different methods.
    The results were as follows.
    Yeast polysauharide; 18.6-30.5%, crystalline hens egg albumin: 17.5-34.9, crystalline harse serum albumin; 25.4-34.1%, γ-pseudo globulin; 21.1%, and Thyroglobulin; 19.7%.
