The oil extracted from the irradiated fried be an curd possessed the strongest i rradiation odor.The paper chromatographic tech nique employed was found not to be an efficient means of detecting the influences of irradiati on. The ultraviolet ab-sorption spectra observed with the irradiated somples were not in accord with the results of chemical analyses, but kmax at 253, 258 and 230 mμ appeared to be of some significance in relation to the effect of irradiation.
The nutritive value of “Koji rice (rice moulded by asperyillus oryzac)” was examined on rats, where nutritive effect of the protein was found to be lower than that of rice. An addition of the alcohol extract of “Koji rice” measurably improved the growth of rats fed with the basal diet consisting of polished rice 84, casein 10, soybean oil 2, salts 4 and vitamin A. When “Koji rice” was supplied in place of rice, the calcification of bones of rats was improved, which indicated the increased available phosphorus in Koji rice as a result of the hydrolysis of phytin in the rice.
The authors have found that equal fractions of the number of raw rice particles are shattered by each successive stroke of an equal count of mastication. The mathematical representation of this statement is N=N0⋅10-kt or log(N/N0×100)=2-kt where N0 is the number of raw rice particle, N is its number after the masticatory stroke (t), and the constant k is the mastication coefficient (masticatory index).
Sodium and potassium contents of fishes were determined by flame photometry. From the standpoint on alimentotherapy (low sodium diet) of edema, the authors investigated whetherthere was any difference in sodium contents of white and lean meat. According to the data obtained, both the white and lean meat contained potassium more than sodium.
Growth tests were made on rats, with the addition of sodium-phytate to the basal diet of low phosphorus, followed by metabolic tests of calcium and phosphorus, to obtain an information about the availability of phytin-phosphorus in the animal. In the growth test, phytin-phosphorus was available evidently but was inferior to K2HPO4, as a phosphorus source. In the metabolic test, the utilization (the absorption) of phytin-phosphorus was lower than that of K2HPO4. Although the absorbed phytin-phosphorus was apparently accumulated in the body, the retention of calcium was diminished by the phytin-P intake.
The blood urea level seemed to have a significance on nutritive physiology as previously reported, where the blood urea content was remarkably increased provided that the low-protein diet was fed for a certain period. Blood urea was measured in this experiment, in which blood urea contents in the case of essential hypertension, kid ney diseases, hepatom, Kimmelstill-Wilson's syndrome often reached a considerably higher level than normal. No seasonal variations in blood urea content were observe.
The rate of transport of radioactive phosphorus (P32) into blood and the effects of several compounds on it had been discussed on the previous reports by using perfusion techniques on rats. In this experiment, the author estimated the rate of transport of P32 into blood of the rats, on the peritoneum of which was sutured the “Tetoron Mesh”(2×2cm.) as a substitutional peritoneum, followed by the intraperitoneal injection of Ringer's solution containing P32. The rate of P32 transport of the rats with “Tetoron Mesh” was increased than that of normal rats. In the case of normal rats, the rate of the transport was increased by the addi-tion of glucose (10-4) M or ATP (10-4M) to the Ringer's solution containing P32, butit was decreased by the addition of iodoacetic acid (10-4 M) or 2, 4-dinitrophenol (10-4M).
1) In those taking a low protein diet, the secretion of adrenocortical hormone decreased to the minimum in the 2nd-3rd weeks, and afterwards showed a little increase without a full recovery. 2) It was made clear by diet surveyings that calorie and total protein in the diet were sufficient but the protein-score of the diet was remarkably low in priests who were in the practice of religious austerities on Zenshu (Zenshu-Sodo) as they were not in the habit of taking animal protein. These facts were c, nsidered as very significant in the daily life of such priests.
