JOURNAL FREE ACCESSVisual sense, especially for moving objects, is important for Lateolabrax in his food-searching, but his sense for water vibration is indispensable and more significant that the former sense in case of going to snap at his food; while his senses for chemical substances are not so essential in any process of his food-seeking.View full abstractDownload PDF (289K) -
XI. On the Denaturation of Fish Muscle Protein Caused by Freezing and Salting, and the Relation between themWATARU SIMIDU, SIGEYUKI HIBIKI1952 Volume 17 Issue 10 Pages 301-304

JOURNAL FREE ACCESSIt has already been reported (2) and also pursued by us that the water-soluble protein of fish muscle get rather more denaturation at near-2°C than at near 0°C. It is thinkable that the fact is attributable to the effect of concentrated salts in muscle itself during freezing. So, we measured the soluble protein in the muscles by adding different amounts of common salt to it and storing within the range of such low temperature as not to be frozen by it. In consequence of this, we found that the higher the concentration of salt, the larger the denaturation of protein was, but there was a maximum point at a certain limit. We considered these facts in connection with denaturation of protein of fish musele owing to freezing and salting.View full abstractDownload PDF (269K) -

JOURNAL FREE ACCESSFrom the other point, the data which have been published by the author are discussed again.
(1) For measuring jellying ability of agar-substanees, it is desirable to reduce the influenee of visco-elastic property of the jelly to be tested as coule as possible.
(2) When the mol-ratio of hexose/total SO3 of each mucilages is taken on the vertical axis and that of total SO3/SO3 in ash on the horizontal axis, all the points of agar-substanees are on a curve nearly parallel to the vertical axis and those of Funori-substanees are on a curve parallel to the horizontal axis. It seems to exist a third curve between the two curves. (Funori is the Gloiopeltis goods)
(3) Jelly-strength is proportional to the mol-ratio of hexose/total SO3 and that of hexose/pentosan. It increases according to the decrease of the mol-ratio of total SO3/SO3 in ash to some extent and then without and change of the latter.View full abstractDownload PDF (282K) -
An Application of Nessler's Colorimetric MethodFUYUO OTA1952 Volume 17 Issue 10 Pages 309-312
Published: May 25, 1952
Released on J-STAGE: February 29, 2008
JOURNAL FREE ACCESSThe adaptability of Nessler's method to the estimation of ammonia in fish meat with the aid of some preliminary treatments was reported in the previous paper.
In the present paper experimental conditions in practising this method were discussed with the following results.
1) The increasing rate of ammonia determined by this method, in the decrease of freshness of fishes and in the fish meats heated under pressure, was nearly parallel with that of volatile basic nitrogen determined by distillation method usually employed.
2) This method made the determination of ammonia contents of various marine produets and other fleshes very easy and simple.View full abstractDownload PDF (194K) -

JOURNAL FREE ACCESSThis is an additional paper to the writer's recent work “The whaling and whale stocks in the adjacent waters of Japan” (Report of the Laboratory of the Nippon Suisan Co. Ltd., 4, 1950; in Japanese). The compositions of the whales caught in 1949 are shown here. The result of a statistical analysis indicates that under existing conditions any increase in the whaling effort in the coastal grounds will turn out ot be unprofitable.View full abstractDownload PDF (568K) -
I. A Method of Age EstimationTAKIO YOKOTA1952 Volume 17 Issue 10 Pages 321-325
Published: May 25, 1952
Released on J-STAGE: February 29, 2008
JOURNAL FREE ACCESSThe method usually used for age determination of teleostean fishes on the basis of the annual rings as observed in the scale, otocyst and centrum cannot be safely applied to elasmobranchs since the characters in question lack certainty in this group.
Casting about any character which may answer this purpose, the present author hit on the clasper length. While the body as a whole grows in this class of the fish almost continnonsly, the clasper lengthens step-wise once a year possibly immediately after the spawning scason. The approximate age thus estimated are shown in Figs. I-III, Tables I-II, and also in Tables III-VIII.View full abstractDownload PDF (583K) -

Released on J-STAGE: February 29, 2008
JOURNAL FREE ACCESSThe following facts have been made clear by our present investigations.
1) The aroma of broiled fish and broiled eel, both prepared with soy and sugar, is attributable to the presence of piperidine as its mother substance.
2) The aroma of fresh fish soup is produced by the reaction of vitamin B1 and glutamic acid monosodium salt.
3) The characteristic aroma of dried cuttle fish is attributable to the presence of taurine as its mother substance.View full abstractDownload PDF (157K) -
III. The Effectiveness of the Liver Extract upon the Atomic Bomb-diseaseTOMIICHI MASUYA, TETSUO TOMIYAMA, YASUO YONE1952 Volume 17 Issue 10 Pages 329-335

JOURNAL FREE ACCESSThe present paper deals with the effect of a bovine liver extract upon the recovery in blood-pictures of several serious cases and in blood and bone marrow-picture of one typically serious case. The liver extract used has been prepared by a following procedure; extract an autolyzed liver with water, add ethanol to make its concentration 70 per cent, concentrate the alecoholie solution in vacuo, and dilute a syrup obtained so as to make 1cc of the resultant solution to correspond to five grams fresh liver.
The comparison between serious cases administered with the liver extract and those without added it has been made of the changes in hemoglobin concentration, red blood cell count and white blood cell count which were observed during stay in the hospital until 30 Sept., 1945 (55 days elapsed after the bombardment). It will be seen from Table 3 that the liver extract was as much effective as the blood-transfusion in increasing the rate of increase in W. B. C. It is also of interest that a simultaneous treatment with both the liver extract and the blood-transfusion gave rise to an outstanding effect in increasing W. B. C.
The examination of blood-and bone marrow-picture of one serious case revealed that the intra-muscular administration of the liver extract was effective in curing a critical stage of a serious type in contrast to some other critical cases which did not receive the liver extract. The change in bone marrow during the treatment with the liver extract is as follows. Nearly complete destruction of bone marrow tissue was observed on 32 nd day after the bombardment; the recovery of R. B. C. system as well as W. B. C. system was under way on 53 rd day (20cc of the liver extract having been administered); mother cells of R. B. C., W. B. C. and blood platelets, and their mature forns were found on 76 th day when 40cc of the liver extract had been administered.
From the above results of the clinical examiuations it can be postulated that the liver extract most probably influcence directly on the regeneration or reactivation of bone marrow tissue. Furthermore, the work recently reported by Carter et al. of the effect of vitamin B12 upon leukopenia produced by irradiation of X-ray, seems to suggest that the active principle effective to the regeneration of W. B. C. in the atomic bomb-disease will not be vitamin B12.
