Flavonoids in Citrus and Related Genera

Abstract: The occurence and distribution of flavonoid glycosides in young leaves and young and mature fruits of many citrus species and trifoliate orange were investigated. The occurence of neohesperidin in both young leaves and young fruits is fairly common to a number of species in subgenus Archicitrus. Ripe fruits of citrus could be classified into (a) the hesperidin group (b) the neohesperidin group (c) the naringin group and (d) the isonaringin group. A new flavanone glycoside, isonaringin, isolated from young fruits of Jagatarayu and Teng mikan is slightly bitter and has been determined by chemical and spectral evidences to have the structure of naringenin-7-rhamnoglucoside. Data showing the occurence of flavanone glycosides in some artificial citrus hybrids were also given.

Mercury content in the blood in relation to dietary habit of the women without any occupational exposure to mercury

Abstract: The dietary record for two weeks from 15 women was arranged according todefined food items. The individual's average daily intake of each food item correlated with the mercury content in the red cell and plasma. A stepwise regression analysis was carried out.By correlation and stepwise regression analyses, only the intake of fish, mainlymarine, was found to be significant in determining the mercury level in the red cell and it explained 80% of the total variance. No significant correlation and regression coefficients were found for the mercury level in the plasma.

Differentiation of the retina and retinal lactate dehydrogenase isoenzymes in the teleost, oryzias latipes

Abstract: The activity of lactate dehydrogenase in the teleost Oryzias latipes, shows a gradual increase during embryonic development, followed by an abrupt rise on hatching, which coincides with the appearance of the retinal isoenzymes. By the time of hatching, the retina has differentiated, and no significant change is observed in the retinal structure until 2 days after hatching. It was assumed that metabolic changes which occur on hatching may trigger the synthesis of retinal lactate dehydrogenase isoenzymes.

Mean circulatory pressure in carotid sinus reflex.

Abstract: Influence of the carotid sinus reflex on mean circulatory pressure was examined in anesthetized dogs with the vagus nerves intact. The carotid sinus reflex was elicited either by occlusion of the bilateral common carotid arteries (9 dogs) or by lowering intrasinus pressure of the isolated carotid sinuses (1 dog). When the reflex rise of arterial pressure was greater than 10mmHg, there also was an increase in mean circulatory pressure up to 2mmHg in 11 out of 20 instances. The increase in mean circulatory pressure tended to be greater as the reflex rise of mean arterial pressure was greater. Thus, when the pressor response was greater than 30mmHg, elevation of mean circulatory pressure was observed in 7 out of 8 cases. It is quite plausible that the control of cardiac output by the carotid sinus reflex is attributable, at least partly, to the Frank-Starling mechanism, since a reflex change in mean circulatory pressure will alter the venous return to the heart.

Application of a shift reagent in nuclear magnetic resonance spectroscopy of esters. An approach for simple identification and simultaneous determination of tocopherols

Estimation of gelatinization and retrogradation of starch by an amperometric titration and its application

Abstract: Gelatinization and retrogradation of starch were estimated by the iodine binding values (lab) which were determined by the amperometric titration with KIO3 of an acidified specimen in both solution and suspension as follows : Gelatinization degree(%)=Iab in suspension/Iab in solution×100 Retrogradation degree (%) = 100-gelatinization degree In the titration of the suspension, a specimen was homogenized with water in a glass homogenizer by hands and was added KCl, HCl and KI to the suitable conditions for the titration. The homogenization conditions did not effect on the determination of Tab when the suspension was apparently homogeneous. In the titration of the solution, the specimen was dissolved in 0, 5 N KOH, acidified with HCl and added KI to be the same composition as in the suspension. Before the determination, specimens were dehydrated well with ethanol, washed with ether and dried over CaCl2 in a vacuum desiccator. The estimation method is specific basically for amylose and, therefore, it is very useful for the analysis of gelatinization and retrogradation of starch. As applications, the retrogradation of potato amylose, amylopection and starch was characterized by the present method together with the glucoamylase digestion and x-ray diffraction procedures.

A Study of the Contents of Dietary Life According to the Health Center Models (Report 3)

Abstract: The contents of our dietary life are subject to many complex social and economic conditions. It causes the diversification of the contents of individual dietary life.This research is conducted on the domestic staple foods for three meals of 514 persons who live in Osaka, Nara and Wakayama in Japan with due regard to their occupations, season and age according to the health center models.Its summary is as follows:1) Side-work farmers (Model U2. U3), jobless persons of over 65 years over (Model UR3) and primary school pupils (Model UR3) take 100% of domestic foods irrespective of season. On the contrary, female students (Model U5) and male students (Model U4) take the smallest percentage of them in winter. Accordingly, female students take the most of their meals out in winter. Regular workers (Model U4) go without meals remarkably in summer.2) As for three meals, male students (Model U3) take the smallest percentage of breakfast in summer and so female students (Model U5) do in winter. Male students (Model U1) take the smallest percentage of lunch in summer, and so female students (Model U5) do in winter. As for supper, however, remarkable differences are not discernible irrespective of season.3) As for staple foods, side-work farmers (Model U1) and their wives, domestic workers (Model L5) and primary school pupils (Model U3) eat rice for three meals remarkably in winter, while primary school pupils (Model U4. U5), regular workers' wives, domestic workers and female students (all-Model U5) eat little or no rice for breakfast.4) Primary school pupils eat the most bread for breakfast, and younger generations eat chiefly raw noodles with bread for lunch. In both cases the tendency is strong in the urban areas. Much raw noodles, rice and bread are eaten in summer, and much raw noodles with bread are eaten in winter.5) The management eat dry noodles for summer breakfast, and rice and dry noodles for winter lunch. Side-work farmers in the small rural areas eat the most rice with raw noodles for summer lunch among assorted meals.As described above, many differences exist in the contents of dietary life.It is necessary to consider this problem in relation to dining out and economic backgrounds. This is intended to be investigated more thoroughly in future.
