JOURNAL FREE ACCESSLow-molecular-weight dextran sulfates readily interact, in aqueous solutions at room temperature, with positively charged substances such as toluidine blue, bovine albumin, and sodium chloride to form a complex. The interaction belongs to a reversible semipolar (or ionic) bond reaction. It is suggested that the dextran sulfates possess a cation-exchange behavior.View full abstractDownload PDF (401K) -

JOURNAL FREE ACCESSA Japanese family of “Bombay” (Oh) phenotype was examined, in whom it was confirmed that both red cells and saliva contained Lea antigen but lacked A, B, H and Leb antigens and that serum contained not only anti-A, anti-B and anti-H antibodies but also anti-Leb incomplete antibody. Immunological experiment with saliva of Oh phenotype revealed that the antigenic specificity related to blood group substance of Oh phenotype would be determined by a carbohydrate, having galactose at the non-reducing end. It was further shown that the amount of the antigenic substance in the saliva mentioned above was decreased considerably, though not so markedly as H substance, in the descending order of secretor, non-secretor and Oh.View full abstractDownload PDF (428K) -
Peroxidase-like Activity and Oxygen-equilibria of the Intermediate and Saturated Forms of Hemoglobin-Haptoglobin 1-1 ComplexShunjiro KAGIYAMA, Shigeru FUJITA, Akira OGAWA, Kazunori KAWAMURA, Tos ...1970 Volume 46 Issue 7Supplement Pages 808-813

JOURNAL FREE ACCESSThe peroxidase-like activity of the intermediate and saturated forms of human hemoglobin-haptoglobin 1-1 complex was markedly higher than that of free hemoglobin, but no difference was seen in the activity of these two complexes under the various experimental conditions studied. Both the intermediate and saturated forms have a high affinity for oxygen with values of n approximately 1 indicating the absence of heme-heme interaction.
From these findings and the data previously reported, it may be said that the configurational changes in the hemoglobin moiety induced by the association with haptoglobin 1-1 and thus the binding mechanism between haptoglobin 1-1 and hemoglobin closely related each other in the intermediate and saturated complexes.View full abstractDownload PDF (543K) -
Isolation and Physicochemical Characterization of the Hemoglobin-Haptoglobin 2-1 ComplexesAkira OGAWA, Shunjiro KAGIYAMA, Kazunori KAWAMURA1970 Volume 46 Issue 7Supplement Pages 814-819

JOURNAL FREE ACCESSEach of the electrophoretic components of human hemoglobin-haptoglobin 2-1 complexes designated in sequence from anode to cathode as Complex I, II, and III was isolated to elucidate the polymeric structures of human haptoglobin 2-1 proteins using preparative zone electrophoresis in acrylamide gel.
Combined with sedimentation and diffusion coefficients, the average molecular weights of Complex I, II, and III were estimated as 169, 000, 245, 000, and 342, 000, respectively. It is reasonable to conclude that Complex I will be a dimer of polymerizing unit of complex, (αβ)Hb(αβ)Hp2-1, Complex II a trimer, Complex III a tetramer, and therefore the polymer series of haptoglobin 2-1 proteins will be integral multiples of the monomeric Hp 2-1, (αβ)Hp2-1.View full abstractDownload PDF (615K) -

JOURNAL FREE ACCESSThe specific antibody to human adult hemoglobin A1 was prepared. And the immunochemical properties of haptoglobin which also binds specifically with hemoglobin were compared with Fig. 3. Complement fixation reaction between Hb Al and (a) antihemoglobin antibody or (b) human Hp. 4: 100% hemolysis, 3: 75% hemolysis, 2: 50% hemolysis, 1: 25% hemolysis, 0: non-hemolysis. those of antihemoglobin A1 antibody. Hemoglobin-haptoglobin shows neither precipitation reaction nor complement fixation reaction under conditions in which hemoglobin-antihemoglobin antibody shows these immunological reactions.View full abstractDownload PDF (676K) -

JOURNAL FREE ACCESSMembrane potential of rat mesentery mast cell was measured in relation to morphological changes of the cell under the effect of compound 48/80 and ATP in the Tyrode medium. Mean of the membrane potentials in resting state was -14.3mV ranging from -6 to -25mV. After the addition of these compounds, the degranulation of mast cell started before the occurrence of depolarization, even though degranulation continued after complete depolarization. This observation suggests that depolarization is not a causal phenomenon in the mechanism of degranulation.View full abstractDownload PDF (599K) -

JOURNAL FREE ACCESSMicroelectrophoretic application of histamine releasers was made to a single mast cell of the rat mesentery. When topically applied close to the cell membrane, compound 48/80, sinomenine, toluidine blue, ATP and a-chymotrypsin all induced a local degranulation associated with the loss of histamine fluorescence in the degranulated area. Extruded granules showed no fluorescence.
Intracellular application of these compounds, and also of Ca2+ and Na+, did not affect histamine fluorescence of the mast cell, although n-decylamine caused disappearance of the fluorescence with either intra- or extracellular application.
Metachromatic granules were revealed by re-staining with thionine in the mast cell which had lost histamine fluorescence after a diffuse extracellular application of these releasers.View full abstractDownload PDF (816K)
