JOURNAL FREE ACCESSThe lipid contents of plasma and liver and the fatty acid compositions of plasma, platelets, liver, testes and epididymal adipose tissues were measured in rats fed diets containing different combinations of fish oil and corn oil. While no significant differences were observed in plasma triglyceride levels among the experimental groups, plasma cholesterol level decreased as the proportion of dietary fish oil increased. However the levels of cholesterol and phospholipid in the liver increased with an increasing proportion of dietary fish oil. In plasma, liver and testes, the percentages of C20: 5 (n-3) and C22: 6 (n-3) were reduced as the proportion of dietary fish oil decreased and the percentages of C18: 2 (n-6) and C20: 4 (n-6) increased as the proportion of dietary corn oil increased. In platelets, the percentage of C18: 2 was high and that of C20: 4 was low in the groups receiving more than 50% fish oil, while opposite results were seen in the groups receiving more than 75% corn oil. The C20: 4/C18: 2 ratios varied in each tissue and also among the dietary groups receiving different combinations of fish oil and corn oil.View full abstractDownload PDF (1620K) -

JOURNAL FREE ACCESSA factorial experiment was conducted with multiparous rats (6 months old on average) fed one of eight diets prepared according to an L8 (27) -type orthogonal design for 13 weeks to determine the influence of dietary protein, calcium and phosphorus on kidney, femur, and utilization of calcium, phosphorus and magnesium. Factors studied were protein, calcium and phosphorus content in the diet and feeds were prepared containing both the standard amount according to AIN-76 and double the amount. The results obtained were as follows: 1) An increase in protein intake alone caused an increase in urinary calcium, but no change in calcium absorption. An increase in phosphorus intake alone caused a decrease in urinary calcium excretion. A concurrent increase in protein and phosphorusintake caused a decrease in urinary calcium excretion. 2) A high protein or a high phosphorus intake caused a significant increase in kidney weight. A high phosphorus intake increased markedly the concentrations of calcium, phosphorus and magnesium in the kidney. 3) Pathological examination revealed that calcification and degeneration had occurred in the distal parts of the renal tubule due to high phosphorus intake. 4) There were no differences in the effect on femur weight produced by dietary differences in calcium, phosphorus and magnesium concentration.View full abstractDownload PDF (3957K) -

JOURNAL FREE ACCESSThe quality of the gingko nut is known to be adversely affected by unfavorable storage conditions. To elucidate the effects on the nut of time and temperature of storage, compositional changes in carbohydrates and lipids in the nut were investigated. Gingko nuts were stored for six months at three different temperatures, 5°C, 20-35°C, and 37°C, and analyses were made of the moisture, phytic acid, tatal pectin and total lipid and fatty acid contents of the nuts. The nuts stored at 5°C retained a good quality with minirnal campositional changes evident at the end of six months. In contrast, however, almost all the nuts stored at 20-35°C and at 37°C showed mamked deterioration. This deteriorations was characterized by a considerable decrease in the moisture and total lipid contents, as well as a reduction in the amounts of phytic acid and linoleic acid in the lipids, but a constant amount of total pectin was maintained in the nuts during storage at all three temperatures.View full abstractDownload PDF (1095K) -

JOURNAL FREE ACCESSTriacylglycerols (TG) were isolated from rice bran and three types of oil-bearing seed, and their molecular species compositions were determined mainly by reverse-phase high-performance liquid chromatography. Rice bran TG was separable into at least twenty-three kinds of molecular species, among which the major types were POL (palmitoyloleoyllinolein), OOL (dioleoyllinolein), OLL (oleoyldilinolein), PLL (palmitoyldilinolein), POO (palmitoyldiolein) and OOO (triolein). With regard to the component fatty acid distribution at the C-2 position of the TG molecule, linoleic acid was usually richer than oleic acid in POL and OLL species, whereas in OOL species the ratio of the two acids was approximately 1: 1. On the other hand, the principal molecular species of corn, soybean and sunflower TG were commonly LLL (trilinolein), OLL, PLL and POL, but their relative proportions were considerably different from one another among the plant species. Analysis of the TG compositions of eight kinds of rice bran, differing in variety and growing district, and those of four varieties of soybean, harvested in the same regions, showed no significant differences in molecular species among them in either case.View full abstractDownload PDF (1491K) -

JOURNAL FREE ACCESSLactoferrin, lysozyme and immunoglobulins were measured in feces from breast-fed and bottle-fed neonates immediately after birth until 40 days of age. The average concentrations of lactoferrin in breast-fed and bottle-fed neonates were, respectively, 6.5mg/g and trace at birth to 10 days, 3.7mg/g and trace at 11-20 days, 2.1 and 0.1mg/g at 21-30 days and 1.3 and 0.2mg/g at 31-40 days. Fecal lysozyme activities in neonates nursed by breast- and bottle-feeding were, respectively, 213.9 and 95.9μg/g at birth to 10 days, 135.0 and 33.0μ9/g at 11-20 days, 114.7 and 52.5μg/g at 21-30 days, and 97.4 and 43.4μg/g at 31-40 days. In breast-fed neonates, concentrations of IgA, IgG and IgM were, respectively, 2.6, 0.3 and 0.9mg/g at birth to 10 days, 2.0, 0.4 and 0.7mg/g at 11-20 days, 1.6, 0.2 and 0.5mg/g at 21-30 days and 0.9, 0.3 and 0.5mg/g at 31-40 days. The corresponding figures in bottle-fed neonates were trace, 0.1mg/g and trace at birth to 10 days, <0.1, 0.1 and 0.1mg/g at 11-20 days, 0.2, 0.1 and 0.4mg/g at 21-30 days and 0.3, 0.1 and 0.5mg/g at 31-40 days. These results suggest that endogenous lactoferrin in neonates may be produced at approximately 20 days after birth.View full abstractDownload PDF (1255K) -

JOURNAL FREE ACCESSWe examined the effect of fasting on urinary total carnitine excretion in trained and untrained men. Twenty-four-hour urinary total carnitine excretion was markedly higher in the trained group than in the non-trained group. Urinary creatinine excretion also showed a similar tendency. In the trained group, urinary total carnitine excretion was increased with fasting, but not in the untrained group. The rate of decrease in urinary nitrogen excretion due to fasting was greater in the trained group than in the untrained group. These results suggest that carnitine may play an important role in the enhancement of aerobic ability.View full abstractDownload PDF (949K) -

JOURNAL FREE ACCESSQuantitative measurements were made of dietary fiber (DF) in four kinds of vegetable and two cereal products by different analytical procedures including two enzymatic-gravimetric (Asp and Prosky) methods and the neutral detergent fiber (NDF) method. The values obtained by both enzymatic-gravimetric procedures were generally comparable for all samples used. However, the values for vegetables by the NDF method were less than half those determined by the former methods. The influence of the use of enzymes other than those adopted by the AOAC and a reagent kit (No. TDF-100, Sigma Chemical Co.) was also examined with regard to DF values obtained by the Prosky method. The use of crude enzymes on the procedures was found to produce a marked change in the DF contents of some samples. These differences in DF values seemed to be ascribable to the constantly higher blank values obtained by the use of the reagent kit (10.1mg vs 4.2 mg in the standard), which would have resulted in the lower DF contents upon quantification.View full abstractDownload PDF (1139K)
