Nutritive Value of Polymerized Sardine Oil (2)Hideo HIGASHI, Takashi KANEDA, Seinosuke ISHII1951Volume 16Issue 8 Pages 329-334

JOURNAL FREE ACCESSWe reported before our research*, the polymerized sardine oil were not poisonous to the rats and showed more calorific than original sardine oil, at the condition of basal diets including 5% yeast.
In this report we experimented the nutritive value of polymerized sardine oils under small amount of yeast in basal diets.
The results obtained were as follows.
(1) The nutritive value of polymerized sardine oil is influenced by the amount of yeast in basal diets.
(2) In case of diets iucluding 2% yeast, the nutritive value of polymerized satdine oil decreases the value than 5% yeast.
(3) But in this experimental condition, the polymerized sardine oil shows considerable nutritive value and no deficiency symptoms are noticed in each groups.

JOURNAL FREE ACCESSPoisonous pfuffer roe has been processed as food by pickling in rice-bran chiefly in Ishikawa Prefecture.
We have studied periodically the change of toxicity of roe during processing and confirmed the hygienic security of the products.
The decrease of poison in roe to an edible state is proved to be effected by following factors.
1. Exuding of poison with juice separated by salting.
2. Averaging of poison among roes one another by diffusion both during salting and pickling in rice-bran. (This means the marked decrease of poison in especially intensively poisonous roes.)
3. Decrease of poison during pickling in rice-bran perhaps by microorganisms.
Among these factors 2 and 3 seem to be most effective. Moreover, strong salty taste of roe may be another factor to prevent the intoxication, as it does not allow one to lake so much roe as to arouse poisoning.
The pickled roe, which was sold at market, showed to contain some poison though slightly.View full abstractDownload PDF (447K) -

JOURNAL FREE ACCESSIn the light of similarity of pfuffer poison to paralytic shellfish poison, we attempted to assay the former by the method adopted by H. Sommer and others in the estimation of the latter, hoping to obtain more accurate results with a smaller number of mice.
The dose-effect curve of pfuffer poison shows to be just the same as that of the paralytic shellfish poison (Fig. I), suggesting the similarity of these poisons.
The extraction of poison by methanol acidulated with hydrochloric acid, which has been recommended by the American workers in the studies of paralytic shellfish poison proves to destroy the pfuffer poison exceedingly.
Methanol, acidulated with acetic acid (ca. pH 5), is successfully employed without this defect.View full abstractDownload PDF (417K) -

JOURNAL FREE ACCESSThe construction of trawl net, of which a model was made for study, is shown in Fig. 1. The modelling was completed according to TAUTI's Principle of model-net construction. Fig. 2 shows the tention of the warps under varions pulling speeds obtained. In the figure, the upper and lower curves differ in the total numbers of floats from one another. Then, from these two curves we obtained the next formulae
RA=4.27V1.77+0.07
RB=3.80V1.57+0.135
RA and RB denote the tension of the warps and V the pulling speed. considered as the constant 0.07 or 0.135 may be the friction between net and sea bottom, therefore the hydrodynamic resistance of net is calculated as shown in Fig. 3.
The forms of net were photopaphed under the various pulling speeds (Fig. 4). The vertical area of the mouth of net varies with the speed as will be seen in Fig. 5. The hydrodynamic resistance of net (if the form of net does not vary with the pulling speed) can be expressed as (R-C)/a ?? V2. R denotes the hydrodynamic resistance, C the friction between net and sea bottom and a the area of the mouth of net. (Fig. 6).View full abstractDownload PDF (198K) -

JOURNAL FREE ACCESSI soaked the fresh fish in 10 percent of Sodium chloride solution and added a small quantity of acid or salt. I measured the weight of the salted fish, and I found an evident decrease in the weight of the salted fish, when 0.4 percent of phosphoric acid, 0.24 percent of acetic acid, and 1 percent of potassium alum were added.View full abstractDownload PDF (263K) -

JOURNAL FREE ACCESSThe relation between the number of mature ovarian eggs (N) of Salangichthys and the body length (L) or the body weight (W) can be expressed by the formula, N=aL?? or N=a'W??', where a, b, a' and b' are constants. The values of these constants were calculated from the present specimens as follows: (A) for Salangichthys microdon (Bleeker), a=0.1890, b=4.130, and a'=449.9, b'=1.129; and (B) for Salanqichthys ishikawae Wakiya et Takahashi, a=0.008275, b=6.208, and a'=654.8, b'=1.8265.View full abstractDownload PDF (199K) -
