ジャーナル フリーThe authors compared the uptake of Ca45 in the bodies of youg pearl oyster, Pinctada martensii (DUNKER), from filtered and unfiltered (ppt. volume of plankton and other floating materials was 2.6 c.c. /l.) sea water, to each of which Ca45 had been added to show the radioactivity of 4000 cpm/c.c..
After the radioactivity of the plankton reached maximum (Fig. 1), pearl oysters were put in to each group of the sea water and reared for periods from 2 to 72hours. Radioactivity in the mantle, gill, other organs and shell are shown in Table 1 and Figures 2 to 5. Larger amount of Ca45 was incorporated in the oysters reared in the plankton sea water than in those reared in the filtered one. The difference was larger in the mantle than in the gill. By those results gills are considered as the principal organ for the uptake of Ca from sea water, and Ca taken up from plankton through digestive organs seem to be transported to gills in low degree. The amount of Ca45 deposited in the shell reared in the plankton sea water was twice as those in the filtered one, despite that the activity of Ca45 in the plankton was one-hundredth of that of the sea water. That means that Ca are taken up by the oyster in much higher degree from plankton or other floating materials than from sea water.抄録全体を表示PDF形式でダウンロード (344K) -

ジャーナル フリーThe histological observations were made on the acidophil cells and the chromaffin cells in the head kidneys and on the Stannius bodies of 15 species of teleosts (see Table 1).
Surrounding the cardinal veins and its branches in the head kidneys, the acidophil cells are found as densely packed cell groups or as irregular cell cords. On the other hand, the chromaffin cells appear in the walls of cardinal veins and its branches, and sometimes scattering in the acidophil cell groups.
The acidophil cells are stained deeply with eosin and contain relatively large round or oval nucleus, in which a well defined nucleus and a small number of chromatin are found. The chromaffin cells are stained faintly with eosin. The nuclei of chromaffin cells are oval or irregular in shape and are larger than those of acidophil cells.
Concerning the arrangement of the acidophil cells and of the chromaffin cells, six types of their distribution are distinguished (Fig. 3). In Anguilla japonica, neither of them exist in the head kidney, but both cells are confined within the wall of sinous vein near the head kidney (Fig. 3-VI).
The histological structures of the Stannius bodies do not exhibit any wide variation throughout the different species of teleosts. The cells of Stannius bodies contain many siderophil granules, which are stained well with iron-hematoxylin, azocarmine, ponceau 2 R or eosin. Moreover, these granules are PAS-positive, but contain no lipids. These features indicate the condition of active secretion of these cells.抄録全体を表示PDF形式でダウンロード (1360K) -

ジャーナル フリーIn the Inland sea of Japan it has been the practice of catching Pagrosomus major (T. &S.) to use Sibariami (a type of purse seine). In this method of fishing, the fishes are first driven by means of Furinawa into a pack which is then enclosed with the fishing-net so as to be readily landed. (Fig. 1)
In the present work some model experiments were carried out so that the influence of Furinawa exerted on the behavior of fishes might be analysed.
The scheme of model Furinawa here used is given in Fig. 3. The model fishes were ordinary carps, Cyprinus carpio LINEE. The experiments were performed in a water tank as shown in Fig. 2.
Experiment 1. It was investigated the effects of rise and fall of illumination brought on the rate of fish-gathering.
Experiment 2. It was examined the relation between the towing-speed of Furinawa and the rate of fish-gathering.
Experiment 3. It was inquired into the bearing of number of Furiki attached to Furinawa upon the rate of fish-gathering.
The results are shown in table 1-11. On the basis of these data it may well be said that:
1. The rate of fish-gathering remains 0% when Furinawa used without any Furiki.
2. Treating the data statistically for the rate of fish-gathering in correlation to the strength of illumination, a value for the correlation coefficient is calculated as r=+0.5, in an illumination range of 10-150 Lux. In this range the rate attains to 91-96%. In an illumination range of 0-10 Lux, r=+1 while the gathering-rate effected by Furinawa remains only about 40%, thus, the efficiency of Furinawa depends upon the illumination, which has in turn to be of a sufficient Lux for the fishes to see Furiki.
3. The rate of fish-gathering under the influence of Furinawa varies with the towing-speed of the latter. Namely, the variation of the rate changes with the inclination of Furiki, which is in turn determined by the towing-speed.
4. As Furiki increases in number also increases the rate of fish-gathering.抄録全体を表示PDF形式でダウンロード (491K) -

ジャーナル フリーThe purification of GG dipeptidase in pyloric caeca of tunny was made according to the adsorption method.
The results were as follow:
1. Poly-aluminium hydroxide A, ortho-aluminium hydroxide γ, ferric hydroxide, kaolin, fuller's earth. active carbon and celite were used as adsorbents.
When 0.06% ferric hydroxide gel (as Fe2O3) was used, GG dipeptidase was adsorbed but not proteinase, while when 2% suspension of fuller's earth was used, proteinase was adsorbed but not GG dipeptidase. The other adsorbents, they adsorbed peptidase and proteinase together though the adsorbing power differs with each other (Table 2).
2. Under the experimental conditions adopted here, peptidase and proteinase were adsorbed well at pH 4.0-4.5, and scarcely at pH higher than 6.0 (Table 3).
3. Peptidase and proteinase adsorbed were both eluted with 1% Na2HPO4 (pH 7.5-8.5) and 0.05 N NH4OH (pH 9.0-10.0), and pH was found to exert no effect on elution (Table 4). The elution percentages of the enzymes from ortho-aluminium hydroxide γ was the least showing 23.2% in GG dipeptidase and 36.7% in proteinase, and those from the others were 51.2-90.2% in GG dipeptidase and 49.5-97.3% in proteinase (Tables 4 and 5).抄録全体を表示PDF形式でダウンロード (485K) -

ジャーナル フリーThe present investigation was made in order to isolate and purify the GG dipeptidase and proteinase in pyloric caeca of tunny.
The results were as follows:
When the glycerine extract of the pyloric caeca was treated with 0.06% ferric hydroxide and the enzyme adsorbed was eluted with 1% Na2HPO4, the GG dipeptidase free from proteinase was obtained in the yield of 51.2% and in the 18.7 times specific activity of the original solution. On the other hand, in the same experiment with 2% fuller's earth, proteinase free from the dipeptidase was obtained in the yield of 44.6% and in the 36.5 times specific activity, as shown in Table 2.抄録全体を表示PDF形式でダウンロード (224K) -

ジャーナル フリーFor removing the membrane of dog salmon egg a single treatment of it with proteolytic enzymes is not sufficient. Enzymatic dissolution of the egg membrane is attained only for the eggs that have previously been treated with acid solution. The most suitable procedure for removing the egg membrane is composed of a series of treatments as follows: 15 minutes immersion in acidulated RINGER'S solution (pH 1.8) → washing with normal RINGER'S solution → immersion in 0.2% pancreatin-RINGER'S solution (pH 11.0). The egg thus denuded is still fertilizable.
Pancreatin enzymes effective for dissolving the egg membrane are likely to be tryptic enzyme and cathepsin.
The double treatment with acid and pancreatin solution induces egg activation without breakdown of cortical alveoli. About this phenomena some discussion is presented.抄録全体を表示PDF形式でダウンロード (1286K) -

ジャーナル フリーSucceeding to the previous paper, the present paper deals with the specificity of mackerel liver enzyme on the oxidation of fatty acid and Vitamin A.
This enzyme exhibits optimal activity at pH 6.8-7.0 (Fig. 1) and at 17°C. (Fig. 2). Though the optimum pH resembles to the other results, but the optimum temperature do not coincides with the other results on lipoxidase. From this study we can not certify the mackerel liver enzyme is the same with the soy-bean lipoxidase or not.抄録全体を表示PDF形式でダウンロード (194K) -

ジャーナル フリーIn the former paper the authors examined experimentally the polarography of rancid fish-oil and obtained an interesting result.
Since the decemposition products of fats and oils are known to contain some volatile substances, so we examined in this report the application of polarography to the volatile compounds in rancid fats and oils.
The aeration method was used because the volatile substances are easily expelled by the air current and catched by the solution which works at the same times as the supporting electrolyte in the polarographic technique.
A chromatography on 2.4-dinitrophenylhydrazones of the volatile components has been carried out and the results were discussed of their relation to the above polarography.抄録全体を表示PDF形式でダウンロード (311K) -

ジャーナル フリーIn the former paper the authors obtained a well defined polarographic wave which was caused by the oxidation products of fats and oils. It seems that the compound to produce the polarographic wave in oxidized fat and oil is not caused by a single substance, but several substances are related to it. Therefore in this report the authors describe a trial to separate the volatile compounds produced during the autoxidation of fats and oils by the systematic steam distillation. In this report the following results are obtained.
1) A well defined polarographic wave given by the volatile portion of the oxidized fats and oils had a half-wave potential of -1.9 V vs. S. C. E.
2) Separation by steam distillation revealed that the compound giving polarographic wave was aldehyde fraction of the volatile matter formed in the autoxidation of the fats and oils.抄録全体を表示PDF形式でダウンロード (235K) -
