ジャーナル フリーIn view of the recent demonstration of the lack of intrinsic factor activity in dog gastric juice, both B_<12> absorption and the role of gastfic juice were investigated on cats, among carnivorous species. About fifty cats were used in the study, and absorption of ^<57>Co-B_<12> placed in a cleaned and ligated ileal segment was measured. It was found that 0.005-0.03μg of B_<12> was poorly absorbed while absorption of doses above 0.2μg was good. Coadministration of neutralized gastric juice invariably reduced absorption, while dog or human pancreatic juice collected from the duodenum under the influence of Pancreozymin and Secretin increased absorption of small doses of B_<12>. Similar enhancement of absorption of small doses of B_<12> was achieved by rat stomach mucosa extract. The presence of EDTA in the loop, however, did not interfere with the effect of rat intrinsic factor; different absorption mechanism of small amounts of B_<12> in cats was suggested in comparison with species known to have intrinsic factor. These findings in the cat including the B_<12> binders in gastric juice demonstrated by column chromatography and gel-filtration are very similar to those recently reported by Kitazaki in the dog.抄録全体を表示PDF形式でダウンロード (859K) -

ジャーナル フリーAlthough the speed of B_<12> turnover in man has been estimated to be slow, little is known about the route of B_<12> loss. The present study was designed to determine the speed of B_<12> turnover and the routes of B_<12> loss in rats, using a specially designed whole body counter, and the role of small intestine in B_<12> loss. It was found that the major portion of subcutaneously injected ^<57>Co-B_<12> was lost in feces and the biological half life of B_<12> after settlement in tissues was about 32 days, with a fair correlation between decrease of radioactivity from body and increase in cumulative fecal excretion. Excretion into intestinal fluid as collected from the end of duodenum was smaller than that from the ileal end, and the total radioactivity present at one time in mucosa was not large enough to account for fecal excretion. It is suggested that there is a constant uptake of B_<12> and loss of B_<12> by the intestinal mucosa. Intermittent administration of sublethal doses of x-radiation resulted in retardation of decrease in mucosal radioactivity, and preparation of large emptying intestinal loop demonstrated accelerated turnover of mucosal B_<12> in the bypassed segment.抄録全体を表示PDF形式でダウンロード (885K) -

ジャーナル フリーTo study the correlation between pyruvic acid contents and thiamine deficient cardiac lesions, the pyruvic acid contents in blood and organs of thiamine deficient, control pair fed and normal rats were determined. It was found that pyruvic acid accumulation in blood and especially in heart muscle, is the strong factor of thiamine deficient cardiac lesions.抄録全体を表示PDF形式でダウンロード (821K) -

ジャーナル フリーTPD, when incubated with Escherichia coli, was reduced to thiamine and practically all the reduced thiamine was found in the medium, not in cells. There is no difference between reduction of TPD by spheroplasts and that by intact cells. TPD was shown to be reduced equally by ghosts or cytoplasm. Uptake of TPD by E. coli was greater than that of thiamine. TPD uptaken into cells was detected as phosphorylated thamine and free thiamine but not as TPD. Free thiamine was detected more highly in the case of TPD uptake. TPD uptake was not dependent on energy source and not inhibited by pyrithiamine and deoxythiamine in contrast with thiamine uptake. TPD uptake ceased at about 30 min, but occured again when the cells were suspended into fresh medium containing TPD. Release of intracellular thiamine compounds into medium was not observed. On the other hand, TPD uptake was similar to the mode of thiamine uptake in the low concentration of TPD.抄録全体を表示PDF形式でダウンロード (653K) -

ジャーナル フリーMeasurement of specific gravity, haemoglobin content, haematcrit value and pantothenic acid content on blood samples of rural female inhabitants over 40 years of age was carried out. The level of bound pantothenic acid in blood declined with age and its decreasing tendency was remarkable between subjects in the age classes of 40-49 years and 50-59 years, although free pantothenic acid contents were found to be almost constant in each age group.抄録全体を表示PDF形式でダウンロード (391K) -

ジャーナル フリーThe level of the four types (pyridoxal, pyridoxamine and their phosphates) of vitamin B_6 in blood of rabbit had been investigated at different time after an oral administration of vitaimin B_6 derivatives, including N-(4-pyridoxyl) dehydrohomocysteine thiolactone (PAL-DHT). After an oral administration of PAL-DHT to rabbit, total vitamin B_6 level in blood was markedly greater than that of administration of other vitamin B_6 derivatives, and reached a maximum 4 hours later, and about 80% of total vitamin B_6 was recovered as pyridoxamine phosphate (PAM-P). When PAL-DHT was injected in the ligated intestine in situ, a large quantity of PAM-P in the mesentric vein blood was recovered. These findings suggested that PAL-DHT might be readily metabolized to PAM and phosphorylized to PAM-P in the transporting process through the intestinal wall. And the differential patterns were observed in the increased level of vitamin B_6 in blood after administration of PAL plus DL-Homocysteine mixture and PAL-HCySH. Also the half-life of total vitamin B_6 in blood after oral administration of vitamin B_6 derivatives were calculated respectively.抄録全体を表示PDF形式でダウンロード (468K) -

ジャーナル フリーThe kidneys of rats treated for 30 to 50 days with the experimental Vitamin B_6 deficient diet with normal or low magnesium content were examined by electron microscopy. Slight increased number of vacuoles and lysosomal bodies were observed in the proximal convoluted tubuli of vitamin B_6-deficient rats, and the cell debris was prominent in tubular lumen. On the other hand, in the proximal convoluted tubuli of the rats lacking vitamin B_6 and magnesium, the abundant large lysosomal bodies appeared in cytoplasms and the tubular lumen contained the numerous cell debris which had the similar appearance of cellular organelles seen in the proximal tubuli. These observations suggest that the primary step of urinary stone formation is the apatite which is formed in the proximal convoluted tubuli by magnesium depletion and in secondary step the oxalate which is excreted increasingly by vitamin B_6-deficiency precipitates on this apatite.抄録全体を表示PDF形式でダウンロード (1852K) -

ジャーナル フリーTreatment of retinoic acid in cyclohexane with 74%-sulfuric acid, followed by dilution with water, gave a fluorescent product which was extracted with cyclohexane, showing maxima at 333mμ in the excitation spectrum and at 425mμ in the emission spectrum. The fluorescent product was shown to be stable to heat, though very labile to light. The fluorescence intensity was completely proportional to the concentration of retinoic acid (0.2-100.0μg). Therefore, this method will be available for the determination of retinoic acid.抄録全体を表示PDF形式でダウンロード (449K) -
