ジャーナル フリー1. Some adult fish come up to the southern sea of Kyushu and near Amami Islands in the winter.
2. 89 larvae of the length 5.2-21.2mm were caught by the larva net in the southern sea of Kyushu. The distribution of the larvae was studied. It was made clear that these larvae were distributed up to far more southern than formerly thought.
3. The period of capture of the larvae is between January and May, the temperature of surface water was 19.5-23.4°C, and the southern limit of capture was at 25°-37° N.抄録全体を表示PDF形式でダウンロード (282K) -

ジャーナル フリーHijikia fusiforme is an edible fucaceous alga, growing in tidal zone in Japan. It sheds eggs periodically at the intervals of seven to eight days (cf. Table 1), from the end of May (water temp. 19°-20°) to early July at Misaki, Kanagawa Prefecture. Shedding occurs in a flood tide of day-time. About 105 eggs are shed from a female plant in a season.
As was reported (Tahara, 1929), each egg is enclosed in a gelatinous coat, the latter of which is attached to the mother plant by a stalk. Under this condition the egg is fertilized and develops to an embryo. In the author's observation, about 24 hours after the shedding, the coat dissolves and the embryo is liberated into the sea water (cf. Fig. 1 and Table 2).
In laboratory experiment, when the sea water containing the liberated embryos is taken on a glass plate, and the water is carefully run off, so as to assure a contact between the embryos and the plate, many embryos are found fixed in one minute. If the embryos are left with an ample sea water, most of them remain unfixed after five minutes (cf. Table 3). The fixing ability is the strongest just after the liberation. Therefore it is right to suppose that, in nature, the embryos will fix themselves to rock surfaces on the following day of the shedding, and they may accomplish it within one minute, especially on the rocks which are washed by waves at flood tide.抄録全体を表示PDF形式でダウンロード (314K) -

ジャーナル フリーIn order to get Some knowledge on multiplying Hijikia fusiforme, an edible fucacious alga in Japan, growth of its bush was observed from 1946 to 1951 at the vicinity of the Misaki Marine Biological Station.
Young buds of the 1 st year become visible in late autumn. In winter they grow in size and put forth some rhizomes. In the successive spring they shed eggs and sperm and then they decay except the rhizomes.
New buds of the 2 nd year sprout from the rhizomes of the 1 st year in the spring, the latter decay in late summer. The buds grow large in winter and put forth several new rhizomes. In the next spring they shed eggs and sperm and then they decay except the rhizomes, the latter put forth buds of the 3 rd year in spring and decay in late summer. The cycle goes on more than five years.
So that the plants of Hijikia are not perennial, but new plants grow annually by asexual repreduction by rhizomes. In this way, plants from a egg make a bush, which is alive more than several years, growing in the first some years as shown in Table 1.抄録全体を表示PDF形式でダウンロード (160K) -

ジャーナル フリーIt has not been ever obtained artificially the mature and fertilizable eggs by any predecessors from the ovary of Mytilus edulis. It was successful in obtaining the numerous fertilizable eggs in my experiment, in which the mantle piece was either stimulated by alternative electric current or by bathing it in M/2 KCl solution for longer than 1 minute. At first numerous immature eggs were oozed out of the out end of genital ducts of mantle by its contraction together with the small, cytolysed eggs, follicular epithelium and many granules. The relaxation of mantle began as its contraction ceased, and thus the exudation was stopped gradually. And then the mantle piece began to ooze out numerous maturing and matured eggs after about 30 minutes of stimulation without mingling any other things. The eggs thus obtained were well fertilizable and developed to swimming larvae. Therefore, it is suggested that KCl solution or electric current act as a stimulant to ovary so as to induce eggs to mature.抄録全体を表示PDF形式でダウンロード (354K) -

ジャーナル フリーWe separated kitol from unsaponifiable matter of blue whale liver oil by chromatographing, and stuied the biological activity of kitol and its thermally decomposed products by animal examination. This preparation had a value of 603 for E (1%, 1cm) (290 mμ), and it seemed to be free from Vitamin A.
The results obtained were as follows.
(1) Kitol has little or no biological activity to the Rats.
(2) The heated products (210°, 5 or 10 minutes in capillary tubes) of Kitel show the same biolgical activity as Vitamin A and this biological potency is better than that estimated physico-chemically with Beckman spectro-photometer.
(3) So we separated these thermally decomposed products to 3 fractions by chromato graphing (Fig. 4, 5, 6) and examined the biological activity of each fraction by Rat-feeding, and we have found that the fraction II (maximum absorption at 325 mμ) show the same biological activety as Vitamin A (Table 4) and fraction I (free from Vitamin A) seems to be some biologically active substances.抄録全体を表示PDF形式でダウンロード (357K) -

ジャーナル フリーA modification of Erdös method has been made of the method and amount of administ ration of phenylhydrazine hydrochloride. A com arison between intravenous administration and intraperitoneal one showed that the latter way of administration gave a consistent time-period for the minimum red cell count (Table II). The administration of thirty mg phenylhydrazine hydrochloride per kg body weight which usually resulted in decrease of 50 to 70 per cent in red cell count, was adopted since its variation during the daily consecutive sampling of the blood over nine days was found within the range of 80 to 106 per cent (Table I).
The reliability of the present method for the estimation of the antianaemic potency in the liver has been discussed. The data obtained for the commercial liver-preparations (Table III) and some discussions on discordant data reported in the literatures led to a conclusion that the method employed could be esteemed to have the appreciabe reliability.抄録全体を表示PDF形式でダウンロード (502K) -

ジャーナル フリーThe minimun daily dose of the liver which after the administration over consecutive three days was effective in prolonging the time-period for the minimum red cell count, was found about 0.5 gr fresh bovine liver per kg body weight (Table I).
By using the above minimum daily dose of a sample liver-extract, accordingly, an approximate estimation has been made on the antianaemic potency in livers of several marine animals. Nearly no difference in the potency has been found between the liver-extracts of whale, yellow tail, shark and bovine (Table I and II). It has been observed in both whale and yellow tail that the subcutaneous administration of an extract of mixture of liver and stomach showed a greater potency than that of the liver-extract only (Table III). A comparison of the results contained in Table IV with those in Table II and III reveals that the oral administration of liver-extract showed a little higher potency than the subcutaneous administration.抄録全体を表示PDF形式でダウンロード (365K) -

ジャーナル フリーIf the shark muscle was preserved from putrefaction while it was yet fresh, no ammonia has been produced from the muscle, but, when the muscle was antisepticized after committing itself to growth of micro-organisms, the development of ammonia was observed. And the longer the period before its antisepticization, the more the amount of ammonia grew. It is obvious, therefore, that the development of ammonia may be proportional to the degree of the growth of micro-organisms. If the muscle was antisepticized when the amount of ammonia reached a certain point, no more production of ammonia has been observed, probably because the secretion of urease from micro-organisms was discontinued. In fact, in examining the action of urease preparation extracted from the muscle at intervals in the course of its storing time, we found that the action of urease from meat, in which the amount of ammonia was on the active increase, was very strong, but it was very weak in the lag period and in the later period of its storage.抄録全体を表示PDF形式でダウンロード (208K)
