JOURNAL FREE ACCESSEthylcellulose microcapsules were prepared by an interfacial polymer deposition technique and fractionated into three fractions of different capsule sizes by passing through a series of meshscreens. The permeability coefficient of the microcapsules towards sodium hydroxide determined electroconductometrically was found to decrease with decreasing capsule size.View full abstractDownload PDF (249K) -

JOURNAL FREE ACCESSFor studying the changes of permeabilities of the erythrocyte membranes obtained from diabetic patients, inorganic phosphate (iP) and calcium in erythrocytes and in sera obtained from the dialysing patients with diabetic nephropathy, from the dialysing patients without diabetic nephropathy and from healthy adults were measured, respectively.The ratio of iP to Ca in erythrocyte was classified into two groups, that is, normal group and diabetic group.The score of iP/Ca was given 20 over as normal group and 5-20 as diabetic group, respectively.And also, the severity of diabetic disease was correlate to this score. The ratio of iP in erythrocyte to iP in serum corresponded to the degree of hypophosphataemia for the dialysing patients with diabetic nephropathy.These evidences suggest that the permeability of erythrocyte membrane obtained from the diabetic patients is varied in some degree compared that of diabetic.View full abstractDownload PDF (751K) -

JOURNAL FREE ACCESSAmphoteric ion-exchange composite membranes were prepared by forming ultra-thin layer of partially quarternized polymer of partially chloromethylated polystyrene, on a porous polyvinylchloride support membrane, and by introducing cross-linkages and sulfonic acid groups intothe ultra-thin layer through dipping the composite membrane into concentrated sulfuric acid.The membrane thus prepared exhibited a similar permselectivity to saccharose as the cellulose acetate asymmetric membrane, but very low permselectivity to sodium chloride.View full abstractDownload PDF (927K) -
Effects of Helix-Making and -Breaking Agents-Akira Shibata, Shinsuke Yamashita, Takuya Yamashita1978 Volume 3 Issue 4 Pages 295-300

JOURNAL FREE ACCESSThe effects of helix-making solvent (DMF), helix-breaking solvents (dichloroacetic acid (DCA), trifluoroacetic acid (TFA)) and denaturantforproteins (urea) on the conformation of poly (-benzyl-Laspartate) (PBLA) monolayers at the air/water interface were investigated by themonolayer technique and the polarized infrared spectroscopy for the collapsed films.
In the presence of urea in the subsolution, the monolayers of PBLA expand and the film transition pressures increase.This may be ascribedtothe breakdown of the hydrophobic hydrated structure around the film in the interfacial region by the action of urea.
In the presence of DMF, DCA and TFA in the subsolutions, the film transition pressures decrease in accordance with the lowering of surfacetension of the subsolutions.From this fact, it seems likely that the conformation of PBLA at the surface is independent of the kinds ofsubsolution.
Polarized infrared spectra of thecollapsed monolayers showed that irrespective of the kinds of subsolution PBLA molecules at the surfaceare in the right handed a-helical conformation different from the left handed a-helical one in the solid state.View full abstractDownload PDF (886K)
