ジャーナル フリーThe fine structure of the corpuscle of STANNIUS in goldfish was examined with electron microscope and the following results were obtained. The cells of this organ contain many secretory granules with a limiting membrane. These granules are osmiophilic, round in form, and about 300 to 1000 mμ in diameter. Well developed rough-surfaced endoplasmic reticulum is observed within the cells. Two types of cells can be distinguished by the distribution of secretary granules and endoplasmic reticulum within the cytoplasm. They seem to be due to the difference in functional state of the same cells. The mitochondria of this organ are of cristae type. Free ribosomes and GOLGI apparatus are recognized. From the results obtained above, discussion was made on the nature of hormone secretion from the corpuscle of STANNIUS in teleost.抄録全体を表示PDF形式でダウンロード (613K) -

ジャーナル フリー1. This study was carried out to prove a hypothesis that the coloration of pearls by irradiation with radioactive-rays may be caused by growing a colored material which was produced from the manganese compound contained in pearls.
2. To obtain marine pearls containing rich amounts of manganese, three adminis-tration methods of manganese, that is, the manganous chloride-sea water immersion method, manganous carbonate paste injection method, and manganese nucleus insertion method were comparatively investigated by measuring the changes of manganese content in the various tissues of pearl oysters.
3. It is estimated that the concentration of manganese in the mantle required to obtain pearl oyster shell having a level of manganese content similar to that of fresh-water mussels should be kept at about 135 to 610γ per g of dry mantle. Such a concen-tration of manganese was obtained by the manganous carbonate injection method (about 100 to 1, 000γ for 5 days) and the manganese nucleus-insertion method (about 30 to 40γ for 6 days).抄録全体を表示PDF形式でダウンロード (462K) -

ジャーナル フリー1. The formation of marine pearls containing rich amounts of manganese, and relationship between the degrees of coloration of pearl layers irradiated with radioactive-rays and their manganese contents were investigated.
2. By the injection of manganous carbonate paste, at a ratio of about 50mg anhydrous matter per shellfish, the manganese contents in the pearl layers of pearl oysters rose to about 300γ per g (about 3γ manganese deposited per pearl of about 4.5 mm in diameter) during 13 days. When manganous carbonate-peanut oil paste was used, the manganese contents rose to about 40 to 67γ per g (1.76γ per pearl).
3. It was recognized that the degrees of coloration of the pearl layer caused by γ-ray irradiation at a dose of 2×107 r for the marine pearl layers containing various contents of manganese are proportional to their manganese contents.抄録全体を表示PDF形式でダウンロード (304K) -

ジャーナル フリーIt is presumed that the salmon in the North Pacific Ocean come up to the surface at dusk and swim near the surface until dawn, and then submerge again to midwater. Therefore, if the hourly variation of netting by the gill-net during night is known, it will explain the phenomenon of the vertical movement of salmon.
With the above idea, the authors carried out the experiments by the hourly interval fishing method in 15 different localities in the North Pacific Ocean and the Okhotsk Sea from early June to early August in 1965. Experiments were performed on the training ship “Hokusei Maru” of the Faculty of Fisheries, Hokkaido Univ. and the research boat “No. 5 Kosho Maru” (Fig. 1).
The set of the test net consisted of 15-20 “tan” (unit) of amilan multi-F. nets which have 100, 106, 112 and 115 mm mesh sizes. These test nets were commonly used for the pink salmon and the mesh sizes were used according to the fishing season and sea area respectively. Fishing operations in each station were repeated in 4-10 series in one night as shown in table I. In this paper, they discuss the tendencies of netting as observed in the vertical movement of pink salmon and chum salmon.
The results obtained are as follows;
1) Two remarkable peaks of catch ratio of pink salmon are found in one night. They are found at 0.2 point (about 1.5 hours) time scale after sunset and before sunrise. The ascending curve after sunset and descending curve before sunrise indicate the characteristic of the vertical movement of pink salmon. The catch ratio toward midnight shows the mean value (Fig. 3).
2) The tendency of the catch ratio of chum salmon in one night resembles that of pink salmon, although the peak of the catch ratio after sunset is not remarkably similar. If the suitable mesh sizes of net had been used, the tendency of catch ratio would have shown more resemblance (Fig. 4).抄録全体を表示PDF形式でダウンロード (530K) -

ジャーナル フリーThe authors have studied the relation between annual variation of hook rate (catch per 100 hooks) and that of age composition, and obtained following results:
1) It is considered that high hook rate was caused by appearance of dominant year classes.
2) The year classes in sub-areas NW, NM and SW, born in 1952 to 1953 are more inferior, and hook rate in these sub-areas from 1957 to 1958 when those year classes is 5 or 6-years are low. The year classes in sub-areas SM and SE, born in 1952 to 1953 are more dominant, and hook rates in those sub-areas from 1957 to 1958 are high.
3) Annual variation of hook rate almost agrees with annual variation of mean body weight.抄録全体を表示PDF形式でダウンロード (410K) -

ジャーナル フリーThe author studied the relation between appearance of dominant year-class of big-eyed tuna and surface water temperature in the tropical eastern Pacific Ocean.
From the study, the dominant year-class seemed to be spawned in the low temperature year, except for the dominant year-classes that were spawned in the year in which the age group caught in this area for the first time had been spawned.抄録全体を表示PDF形式でダウンロード (335K) -

ジャーナル フリーHydrocarbons were isolated from “Nori”, a dry product of Porphyra yezoensis. The samples were produced at Narawa, Chiba Prefecture where a severe disease of the weed has threatened cultivation farmers recent years. One of the purposes of this experiment was to know a differ-ence between hydrocarbon fractions of normal and diseased weed, because waste water of a factory was doubtfully supposed as the cause of the disease.
A major component of the hydrocarbons which was separated from carotenoids by colum chromatography on Florisil (Table 1), was concluded to be octadecene of paraffine by means of GLC, IR spectra (Table 2 and Fig. 1), and refining of urea addition compound. As far as the samples offered were concerned scarce difference was observed between the hydrocarbon frac-tions of the normal and the diseased.抄録全体を表示PDF形式でダウンロード (241K) -

ジャーナル フリーFollowing the last paper carotenoids were extracted from “Nori”, a dry product of Porphyra yezoensis, by a extracting method which yielded the best result than other procedures shown in Table 1, and was summarized in Fig. 1.
While 28.4mg% of carotenoids were found in the fresh seaweed of normal state, 15.1mg% of the pigments were obtained from the diseased which showed severe symptoms on each leaf collected. Of “Nori”, 194mg% and 162mg% of the pigments were contained respectively in the normal and the inferior (Table 2).抄録全体を表示PDF形式でダウンロード (213K) -

ジャーナル フリーThe transport of water across artificial membrane reconstructed with lipids such as cephal-in-and cholesterol-membrane was measured at different concentrations of salts and acids. The results obtained were as follows:
The transport of water across cephalin-or cholesterol-membrane increases with the increase in the valency of anion in the salt and acid solutions, and decreases inversely with the increase in the valency of cation in these solutions.
When the cephalin-membrane was used, the transport increases at first with increasing con-centrations of Na-chloride, Na-glutamate, K-chloride, K-sulfate, K-citrate, hydrochloric acid and sulfuric acid in solution, respectively, until a maximum is reached at definite concentrations, thenceforward, upon further increase of concentration, transport decreases. However, in Mg-chloride or Ca-chloride solution the transport decreases at first with increasing concentrations until a minimum is reached, and upon further increase of concentration, transport increases. In glycine and glutamic acid solutions the transport decreases with increasing concentrations. As for acetic acid solution, as well as sucrose solution, the transport increases with increasing concentrations.
In the case of cholesterol-membrane, the transport decreases with increasing concentrations of Na-chloride, K-chloride, K-sulfate, K-citrate and Mg-chloride solutions, respectively, until a minimum is reached, then, it increases with increasing concentrations.抄録全体を表示PDF形式でダウンロード (373K) -

ジャーナル フリーThe effect of EDTA was observed on the hydrolysis of IMP by an alkaline phosphatase of carp muscle. Results obtained may be summarized as follows:
1. EDTA depressed not only instantaneously the initial reaction velocity, but also time-dependantly the reaction velocity of IMP hydrolysis by the phosphatase. (Fig. 1)
2. The instantaneous effect of EDTA was apparently removed by the addition of excess Mg++. (Table 1 and Fig. 2)
3. During the preincubation of the phosphatase with EDTA, the activity, which was deter-mined after the removal of the EDTA effect by the addition of excess Mg++, was gradually de-creased. (Fig. 3) That is, the phosphatase was gradually inactivated irreversibly by EDTA.
4. The phosphatase was denatured by heat at a lower temperature in the presence of EDTA than in the absence. (Fig. 4)
5. From these results, EDTA was supposed to inhibit the phosphatase reaction by such mechanisms, that EDTA may combine instantaneously and reversibly with a metal ion which is essential to the phosphatase reaction, and the metal free phosphatase thus occurred may gradu-ally and temperature-dependantly be denatured.抄録全体を表示PDF形式でダウンロード (332K) -

ジャーナル フリーIt is a well-known fact that some of B vitamins are synthesized by intestinal bacteria in mammals. Knowledge on fish, however, is still lacking. The present study was planned to see the production of nicotinic acid, pantothenic acid and vitamin B12 by intestinal bacteria of carp, Cyprinus carpio. Bacteria in the intestinal contents were incubated in different culture media and the vitamins were estimated periodically by the microbiological methods. The results ob-tained are as follows.
1. Production of nicotinic acid is inconsistent according to the culturing conditions (Fig. 1).
2. Pantothenic acid shows the increase only after a prolonged culture period (Fig, 3).
3. Unlike the above two vitamins, vitamin B12increases rapidly and markedly, especially at a higher temperature (Fig. 5).
4. Effect of the pH value of medium on the production of nicotinic and pantothenic acids is not significant (Figs. 2 and 4).抄録全体を表示PDF形式でダウンロード (329K) -
